Heart fire

Half an hour ago, when the intervention team started to act, Xi Yang's team had just passed through the substation from the other direction and arrived at the refrigeration room.They also encountered a partial collapse on the way. The accompanying engineer was hit on the head by a colored steel plate because he could not escape in time. Another internal attacker had a problem with the gas cylinder valve. He could only survive by sharing the air of Xi Yang and other teammates. He walked to the hallway with support, and then stayed in place with the injured engineer to wait for rescue.

Xi Yang untied his anti-virus clothing and left his spare flashlight to them. It was at this time that the recording bear was taken out together and fell to the ground accidentally.

Functional equipment such as compressors, coolers, and regulating stations are installed in the refrigeration room, and ammonia pumps, liquid storage tanks, and condensers are equipped in the connected equipment room.In order to achieve better refrigeration effect, large-scale cold storage like Peiyuanyou usually uses cascade refrigeration, that is, two or more refrigerants are used together for refrigeration. This process is compared with a single direct evaporation and secondary refrigerant. Refrigeration is much more complicated and dangerous. Without technical personnel, it is difficult for firefighters to identify and deal with it by themselves.

Before entering the refrigeration room, the two groups of internal attackers were divided into echelons in the same way, and the batches used direct current and blooming water to spray water inside to cool the ammonia-related pipelines while reducing the temperature.Without the assistance of an engineer, Xi Yang, who had seen the pipe color chart before coming in, could only use his memory to distinguish which color and which line were low-pressure gas pipes and high-low pressure liquid pipes. In more than a dozen storage tanks all painted yellow , which one is a high-pressure liquid storage tank made of pressure-resistant steel without refrigeration, and which one is a low-pressure liquid storage tank that is directly vaporized and refrigerated inside with insulation material on the surface.

Many of the criss-crossing pipes showed signs of damage after being heated.At this time, the fire was temporarily suppressed within the scope of the computer room, and it had not yet spread to this point.After a quick and brief discussion, Zheng Jiang and Xi Yang decided to use the vacuum pump and ammonia generator that come with the cold storage to reduce the pressure and oxygen in the equipment room, which can not only prevent the occurrence of smoldering, but also keep the internal attackers in the refrigeration room Continue to spray water outside, buying more time for them to shut off the valve and cut off the source and repair the loopholes in the equipment room.

This is the first time that Xi Yang has cooperated with Zheng Jiang since he was transferred to the provincial special service.

Although I don't know the specific situation, the disagreement between them is already well known. Therefore, when deciding on the candidates, several leaders raised objections, but no matter in terms of physical strength, technology, experience, or ability to act, adapt and command , Among the several teams, no one more suitable than them could be found.Fortunately, the elites who are both on the front line have a very high degree of obedience and professionalism. They did not show any dissatisfaction when accepting tasks and communicating combat plans. Instead, they agreed with each other on some strategies and reached an agreement. It really surprised everyone present.

Xi Yang didn't care and didn't want to know Zheng Jiang's opinion on this arrangement. He only knew that if he had a choice, he would rather carry out the task with someone else, who might be less capable in all aspects.But from the moment he received the order until now, he has never questioned this teammate who has continuously made achievements since he was 20 years old, and he has never thought about whether the opponent will take this opportunity to get rid of him if he is in danger. His threats are almost everywhere. Those malicious people who censor him over and over again, as well as the few cars wandering around the camp from morning to night, can all show that even if he is in danger, Zheng Jiang will not It was so easy to let him go.

At the clubhouse that day, Zheng Jiang believed with absolute confidence that Xi Yang would be subject to his threats and would be tempted by the conditions he offered.He never believes that there is anything pure or absolute in this world, and what he challenges is never Xi Yang, but the common weakness of human nature, the dark side full of greed, selfishness, arrogance, and jealousy.

Rather than saying that he does not believe that Xi Yang is a person without weaknesses, it is better to say that he himself is too eager to become a person without weaknesses, or that he is afraid that what he pursues will be overthrown by the appearance of a perfect person.

Many times, Zheng Jiang didn't even know why he wanted to target Xi Yang.He didn't bother to help the narrow-minded Tao Weinan vent his personal anger, and he didn't think Xi Yang would be a big threat. Not only that, but he could often feel the long-lost bravery, integrity and innocence from this taciturn young man. However, when he heard and saw many people's loyal followers and unconditional trust in him, jealousy occupied his mind, which also made him hate the injustice of fate even more, and almost paranoidly wanted to destroy everything that he originally hoped for. Precious things that should belong to him.

Those who exchange power will disperse when the power is exhausted.There are very few people who can be trusted. He guessed that he may have been walking alone on this cross road for too long and was too lonely, so he was so eager to pull an innocent person to walk with him and sink together.

For example, at this moment, with Xi Yang by his side, this unknown journey to death seems not so lonely and desolate.

It's a pity that he doesn't know that he will be the only one who will fall into the abyss in the end.No matter Xi Yang is going forward or looking back, there are always people following closely and waiting patiently on this road.

I don’t know what’s going on with the intervention team, but Xi Yang firmly believes that Zhou Tong will definitely surprise everyone, just like every time there is a problem between them, Zhou Tong can understand and communicate with each other from a special angle and in a special way. Faced with the same, it always brings him many, many surprises and touches.

In fact, there are still many problems between them who seem to have reconciled, but time does not allow, and there is no need to worry and entangle. At this time, there is nothing more important than getting out alive. Only by living can we see each other again. Only he can start again, and all problems will be solved, as long as they can still hold hands, they will never let go of each other, and they will never be separated.

The trauma and guilt left to Xi Yang in the past were too deep, and the shadow and fear of the fire scene never disappeared, but he learned to hide it perfectly little by little after countless experiences.No one knows how terrified he is when he faces a fire every time he is calm on the surface, and no one can understand the process of him becoming stronger and stronger in adversity. Nirvana in the fire is just people's imagination of him, and the real feeling is only the wound The pain of being repeatedly torn and roasted, lingering, and never recovering.

But now, facing parting and death again, he felt more secure than ever.

It was Zhou Tong who made him believe that neither the past nor the future existed, and no matter what happened in the next moment, the current lover would be waiting to meet him again in another quantum time and space.

...

According to the plan, Zheng Jiang returned to the computer room and started the vacuum pump. After a few minutes, the air in the equipment room was gradually pumped out, and the outside air was decompressed and humidified before filling in, which quickly turned the small space into a hypoxic environment. , suppress and reduce the chance of smoldering occurrence.

There was not much room left for empty calls. After getting ready, Xi Yang and Zheng Jiang crossed the water gun position and entered the equipment room with their tools. Every ammonia pipeline.

The refrigeration compressor in the machine room has been turned off, and the smoke concentration and visibility in the equipment room are much better than those outside. Xi Yang lights up the bright flashlight, starting with the most dangerous horizontal high-pressure liquid ammonia tank, and shutting it down first, which has already leaked The red valve at the upstream of the tank, after the pressure in the tank is properly released from the vent valve, then signal Zheng Jiang, who is guarding the other end, to close the downstream valve.

The condition of the first two horizontal liquid ammonia tanks is relatively stable, and the last ammonia tank itself has no problem, but ammonia gas is leaking from the lower end of the liquid ammonia evaporator connected to it, and the head of the air collecting pipe.Xi Yang thought for a few seconds, and decided to close the fire protection first, that is, the valve closest to the head and not directly threatened in case of fire, but Zheng Jiang advocated that the operation should be carried out according to the principle of "upstream first, then downstream". There was disagreement on this issue.

Through the respirator, Xi Yang tried to keep his words simple and clear: "The pressure relief here has exceeded a certain level. If the upstream valve is closed first, the downstream pipeline may not be able to withstand it."

Zheng Jiang pondered for a moment, but still insisted on his own opinion: "The engineer is not here, and no one's judgment is accurate. It is safer to operate as usual."

What he said was the fact that Xi Yang was not [-]% sure which valve should be closed first, and it is beyond doubt that it would be relatively safe to choose a conservative operation under such circumstances.

So Xi Yang acquiesced to Zheng Jiang's proposal, and closed the pressure relief valve farthest from the head and the most upstream of the ammonia tank according to his request.

The cast steel valves are large and heavy, and require great effort to turn.After operating three liquid ammonia tanks in a row, Xi Yang's hair was completely wet with sweat, and the air pressure alarm began to sound. He didn't delay for a moment, and continued to check the other nine vertical liquid ammonia tanks with his toolbox. , Suddenly, when passing the door of the control room, I heard a small noise coming from inside.

Realizing that there might be someone inside, Xi Yang quickly reacted and knocked open the door of the control room, and joined forces with Zheng Jiang to drag a man in overalls out of the gap on the side of the console.

Close the door, keep the smoke and leaked ammonia out, and you can still breathe in the control room less than five square meters.The trapped worker coughed and told Xi Yang that he was working when the fire broke out and had not received an evacuation notice. When the ammonia gas was leaked, it was too late to escape, so he had to hide in the control room and use the only thing left in the thermos to escape. Wet a pair of gloves with a little water, covered his mouth and nose and waited for search and rescue.

Xi Yang’s breathing apparatus was running out of air, so Zheng Jiang took off his respirator and put it on for the workers, and made a decisive decision: “I’ll take him out to join the internal attack team, hurry up and close the valve, 5 After a few minutes, regardless of whether it is closed or not, it will be withdrawn! Is it okay?"

When liquid ammonia vaporizes, its volume will expand more than 800 times, and after absorbing a large amount of heat, it will form a low-temperature gas at minus [-] degrees, causing frostbite to the skin.At the same time, liquid ammonia is also highly alkaline and highly toxic. Once it enters the human body through the respiratory tract, skin or eyes, it will slow down breathing, damage nerves and cause the dissolution of cells, tissues and organs, which can cause death within a few minutes.

Xi Yang grabbed Zheng Jiang, trying to stop his crazy behavior: "You are looking for death if you go out like this!"

In fact, there is no need for Xi Yang to remind, Zheng Jiang knows better than anyone else the consequences of going out without wearing a respirator, but he does not expect others to understand, if he does not have this overly arrogant self-confidence, how can he make those orders again and again What an amazing feat.

"The current ammonia concentration is at most sixty to seventy milligrams per cubic meter, and the nasopharynx is just a bit irritating." After Zheng Jiang said that, he shook off Xi Yang's hand. "Don't waste time, if you can't complete the task by yourself, just say so!"

Xi Yang didn't understand why he was competing at this time, but before he had time to persuade, Zheng Jiang had already held his breath and rushed out with his people.

At his speed, even if he still needs to bring another person, it won't take too long to pass through the [-]-square-meter equipment room.Xi Yang followed closely behind, separated from them when passing the third horizontal liquid ammonia tank that had been processed before, turned around and walked towards the nine vertical liquid ammonia tanks on the other side.

But at the moment he turned around, the liquid ammonia evaporator suddenly made a loud noise, and the head of the air collecting pipe at the lower end finally fell off because it could not bear the huge pressure, and instantly burst out with a large amount of leaked ammonia vapor, frantically Spray on Zheng Jiang's exposed head and face!

At the juncture of life and death, Zheng Jiang subconsciously pushed the worker next to him to the ground and protected him under his body. At this time, Xi Yang, who had a very quick reaction, also turned around and rushed over, using all his strength to push him to the ground. The two were dragged out of the strong ammonia gas, dragging them to quickly evacuate outward without stopping.

Ammonia is soluble in water and can be extinguished with water.The internal attack team was still guarding the outside position and continued to shoot water into the computer room. Suddenly, everyone saw a stumbling figure appearing in the billowing smoke, and shouted loudly to them while advancing hard: "Water! Save people! Save people quickly!"

It was too fast, everything happened too fast, it took only 3 minutes before and after, when Xi Yang took over his teammate's respirator, he was finally able to take a big breath, after he calmed down, he looked at Zheng Jiang who was lying aside, he was already having difficulty breathing, Almost unconscious.

Inhalational ammonia poisoning can cause edema in the throat and lungs, and the mucous membrane of the respiratory tract will also fall off, blocking the trachea.Xi Yang knelt down to perform cardiopulmonary resuscitation and artificial respiration for Zheng Jiang. He kept trying to wake him up, keep his consciousness, and ordered him not to speak with sobs, but his pupils still became dilated little by little. The voice from the throat was chaotic and dilapidated, not like a human being.

Hate him, hate him, but Xi Yang can't give up on him, can't give up on the rescue mission: "Stop talking...I can't hear you clearly, stop talking...I'll take you out right away... ...Zheng Jiang...Zheng Jiang! Don't die!"

"You fucking bastard! After doing so many unconscionable things, do you want to die like this? You bastard!"

Zheng Jiang smiled, the smile was ugly and distorted, his frostbitten face no longer had the confidence that was inevitable.

Xi Yang put his ear close to his mouth, trying hard to distinguish every intermittent and incoherent utterance of his words.

"Oil line...brown...salt...brine line...green...color...valve handle.... ..crimson..."

"Block...block..."

"Remember..." Xi Yang clenched Zheng Jiang's anti-virus clothing and responded loudly in his ear: "The oil pipe is brown, the brine pipe is green, the handle of the expansion valve is dark red, and the handle of the shut-off valve is yellow! I Remember, I will block...don't say any more!"

The lack of oxygen gradually paralyzes the nerves.Hearing his words, Zheng Jiang closed his eyes in satisfaction, almost suffocating but refused to stop to rest.

"It's not... only you... OK... It's a pity... In the next life... don't be an enemy..."

"Xi...Xi team...well...well...live...well...no shame..... .No regrets..."

The ammonia gas was diluted, and newly assigned engineers and rescue teams were on their way.Zheng Jiang's voice became weaker and more desperate, and was soon swallowed up by the sound of water, collisions, and cracking of the board, and disappeared into the chest that had no heaving ups and downs.

At the same moment, another voice full of vitality and touching came from behind, and as the steady and firm footsteps got closer

"Instructor! Xi Yang!"

Xi Yang looked back in the corner, through the mask, through the bitter tears, through the obstacles and difficulties, he saw a pair of bright eyes in the chaos and darkness, and there was burning hope in those eyes.
