Li Wenjun patted his shoulder: "If you are interested in the specific situation, you can check the information. As far as I know, there have been three or four major accidents in domestic air separation equipment in the past ten years. If you are interested,
You can also check it out. I asked you to check it out not only to remind you that safety is very important. The most important thing is to ask you to understand the cause of the accident so as to avoid it happening again."
Tao Guangming was still confused: "Does this have anything to do with the wind direction?"
Li Wenjun said: "If the suction port of the air separation unit is in the downwind direction, hydrocarbons and nitrous oxides are sucked in. These flammable and combustion-supporting substances will enter the air separation system and mix with oxygen. Acetylene, in particular, is the most dangerous.
The solubility in liquid oxygen is very low, and it is easy to precipitate in the solid state and cause an explosion. Once inhaled..."
Dong Qingjun cooperatively shouted "bang" in Tao Guangming's ear, which made Tao Guangming tremble with fright.
Li Wenjun said: "So you need to go to the weather station to check the dominant wind direction of 'Wenjun New Town', especially in summer. Anyway, judging from the wind direction I just measured, the air inlet of your equipment is basically downwind of the entire factory area.
It can be judged to be unqualified. Imagine that the methane discharged from the anaerobic tank of the sewage plant is a flammable and explosive gas. If it is blown by the wind to the gas plant, it is then sucked in by the suction port."
Tao Guangming wiped his cold sweat and wrote it down in his notebook, and drew two big five-pointed stars to express importance.
Li Wenjun took a few more steps and said: "The location of the office is not up to standard, the ventilation measures are insufficient, and there is no emergency exit. If liquid nitrogen leaks, it will be very dangerous."
Tao Guangming said: "Don't coax me. Nitrogen is separated from the air. It does not burn, does not support combustion, and is not toxic. I also plan to use it to make popsicles."
Li Wenjun laughed angrily: "You must be crazy. The boiling point of liquid nitrogen under normal pressure is minus 196 degrees Celsius. Do you know what that means? The maximum temperature that liquid nitrogen can maintain in its liquid state is minus 196 degrees. You can use it to make popsicles without worrying about yourself.
Are your hands frozen off?"
Tao Guangming felt terrified when he heard this, but he still said stubbornly: "It's okay if you don't make popsicles. Just tell me why liquid nitrogen leakage is dangerous."
Li Wenjun: "Pure nitrogen is denser than air. A leak of liquid nitrogen will form a hypoxic gas layer on the ground in a short period of time. People will become comatose and suffocate to death without even a chance to escape."
Tao Guangming looked at the office building with only one exit.
Li Wenjun added: "Pure oxygen systems require more stringent requirements, otherwise they are prone to explosion. All pipelines must be tested for leaks and pressure."
Tao Guangming kept wiping his sweat, but still said harshly: "Really or not, I always feel that you are talking nonsense to scare me."
Li Wenjun: "You will know after you check it out."
After leaving the air separation plant, we went to see the military factory.
Dong Qingjun stopped following Li Wenjun and the others because he knew that even if he followed, he would be stopped outside, so he went to the library to look up information on his bicycle.
The military factory now produces communication equipment, armored vehicles, helicopters, bulletproof off-road vehicles, and recently added the research and development of military drones.
Because after the last air show, Jiang Qiangjun and Yang Shouzhuo suddenly realized that loading light weapons or cameras on drones would be a perfect offensive or reconnaissance equipment, and then allocated funds to Li Wenjun to start developing this.
The amount of R&D funds they approved is quite large. It can not only make up for Li Wenjun’s previous investment in UAV research, but also ensure the development of better models.
These research results can also be applied to civilian applications in the future.
For example, drone positioning and navigation can be used in cars in the future.
In other words, Li Wenjun once again successfully achieved "using other people's pots to cook his own food."
Tao Guangming always said that Li Wenjun engaged in military industry just to "spend money and make a noise", but now he gradually understands Li Wenjun's purpose.
This is an industry where there is a steady stream of big customers coming in and you don’t have to worry about selling anything.
This expansion is also to divide the production of large machinery and small equipment into two areas.
After all, some equipment requires dust-free workshops and temperature and humidity control.
The institute will also move in in the future.
In the future, this area will become the "heart" of manufacturing and R&D in "Wenjun New City".
Everyone is carefully vetted before being allowed to work.
And there is a cliff behind it, and the wall in front is three meters high, with a power grid and monitors. Unless you can fly out, there is only one exit.
People are searched every time they go out and in, no one is exempted.
Security guards from "Civil Military Industry" and soldiers with guns stood guard at the door.
But Li Wenjun knew that even if this was the case, spies would inevitably sneak in.
So he requested that in some core areas, except for him and Yang Shouzhuo, only designated personnel could enter.
Moreover, you need to swipe your work card at the door, and there are also the latest iris and fingerprint recognition locks.
Tang Zhaonian once lamented that the security level at Li Wenjun's place had long surpassed that of a prison, and was stricter and more high-tech than anything seen in movies.
Dong Qingjun had no problem entering the general area, but he was lazy and often didn't bring his card, so he couldn't get in.
Jiang Qiangjun and Yang Shouzhuo assigned the construction department of the General Logistics Department to be responsible for the expansion of the military factory, and did not ask Tan Dailei to do it.
Tan Dailei is now too busy to build various high-rise buildings and residences, so he has to take on this tricky and sensitive project.
All workers and technicians will live and eat inside the wall until it is completed.
Now the civil engineering work has basically been completed, mainly equipment installation, so most of the workers will leave today.
Most of the technical staff knew Li Wenjun, but no one made any special remarks and just nodded to say hello to Li Wenjun.
Li Wenjun never liked others in the factory to engage in personality cults and brag about flattery.
If someone is busy and interrupts work to greet him for no special reason, it may make him unhappy and feel that this person is not professional enough.
Li Wenjun walked around silently, watching everyone install precision machine tools and photolithography machines. Looking at the progress, the trial operation should be completed within a week.
Tao Guangming is no longer nervous now. The construction here actually has little to do with him. The reason why he came to inspect it today was purely to torment Li Wenjun.
Thinking about it now, it seems that he was the one who suffered in the end.
When it was time for lunch, the canteen of the military factory was ready and delivered.
This is also to avoid the trouble of having to check IDs again when everyone comes in and out at noon.
Yang Shouzhuo happened to be there today. When he came down from the confidential area, he saw Li Wenjun slightly raising his eyebrows at him.
Li Wenjun smiled: "I'll help you."
Yang Shouzhuo sneered.
How funny.
The factory was his, and he wanted to come and make a living.
Come for inspection, come for inspection, why are you saying so politely?
Li Wenjun caught a glimpse of a dark, thin worker wearing a safety helmet and a T-shirt coming from the confidential area, and stared at the man.
Yang Shouzhuo was very familiar with him, and when he sensed danger, he would show such a cold look.
