Medical Elders, But Biography Wen Develops Shoes Factory Benzene Pollution Control Equipment

In recent years, chronic benzene poisoning has caused more and more cases of leukemia.

This makes Chengdu retired from the medical school, but the biography does not hold water.

He spent more than 40 thousand yuan at his own expense, and spent 5 years to develop a set of shoe factory benzene pollution control equipment.

But Chuan Wen intends to authorize his patent to Sichuan shoe factory for free, as long as the shoe factory is willing to use this equipment to prevent benzene poisoning.

Benzene compounds have been identified as strong carcinogens by the WHO.

It is understood that at present, tens of thousands of shoe factories in China use cold sticky technology to make shoes, and each year uses about 100000 tons of adhesive, including three benzene, ethyl acetate, butyl acetate, cyclohexane and cyclohexanone, and millions of workers sit in front of the crude workbench or on both sides of the waterline. They use hand to smear the adhesive on their shoes. At this time, benzene organic chemical poison is volatilized from the adhesive, diffused in the air of the workshop, and enters the human body through the respiratory tract, endangering the health of the workers, resulting in some workers suffering from aplastic anemia or leukemia.

Some shoe factories had to shut down because they were poisoned by benzene and unable to afford huge medical expenses.

There are many shoe factories in Chengdu.

Once I was in charge of occupational disease prevention, I saw an idea once I saw the news of benzene poisoning among shoemaker workers: we must find a feasible way to prevent benzene poisoning.

"Environmental protection is relatively weak in China.

I used to be the state's money to read books. Now that I retired, I hope my knowledge will still play a role.

This idea made the persistent old man spend 5 years and spent more than 40 thousand yuan in his family. Finally, he successfully developed a shoe factory benzene pollution control equipment this year.

Yesterday, the reporter saw the design of the device.

Under the ventilation and gluing worktable, under the hood and ventilation pipe, 6~8 people can work at the same time. Ventilation, glue spreading and air drying are all carried out here.

But the text opened the machine and the smoke on the platform actually floated to the ventilation pipe.

Then, toxic gas is pmitted to the spiral spray pressurized absorber.

Through the pressurization and multistage spray washing, the mist flow is formed in the tower, which increases the dispersion and contact time of the gas and liquid, and the waste containing benzene is absorbed into the absorption liquid.

However, the compound three benzene absorption solution prepared by biography is composed of water and chemical raw materials, and the absorption efficiency is 99.07% after being tested by Chengdu CDC.

In this way, the gas discharged from the factory is clean.

The research of the elderly has also been supported by the Wuhou District science and Technology Bureau, which encourages the elderly to apply for research funding within 20 thousand yuan.

But Chuan Wen said he intends to authorize his patents to Sichuan shoe factories for free. As long as the shoe factories are willing to use their own equipment to prevent benzene poisoning, the environment is better.
