Coating waste gas "bath" can be re used

A mention of coating factory, it seems to be able to smell the smell of a chemical substance. As the coating plant, the concentration of Dongyang Weishan Town Bai Tan Cun, above the village is often filled with a shares similar paint smell, the smell is part from more than 10 vacuum coating factory. Thankfully, it doesn't take a long time, so the situation will be changed.

Yesterday morning 9 when running in Dongyang City Bai Tan vacuum coating factory workshop of two large machines are high speed under the scorching sun. "Don't underestimate them, but this two Taiwan environmental protection energy conversion equipment. Can not only purify the exhaust gas produced by coating, but also can be converted into energy, recycling." Coating factory responsible person Wu Shaoliang explained.

According to the coating production process, the waste gas mainly from the drying process, the discharge of pollutants mainly for drying volatile organic matter, smell a bit like paint smell, but also mixed with alcohol.

"Organic matter is heated in the process of drying, it turns into gas, and the odor is very smelly. The environment protection energy conversion equipment is to purify harmful gases through air cooling, low temperature combustion and so on." Wu Shaoliang said, purification is on the one hand, more importantly, after the treatment of gas can be converted into energy, through the pipeline recycling, and can be used for the operation of the machine. Simply said, that is to achieve the recycling of energy."

Wu Shaoliang coating plant has been operating for 22 years, in order to process the golden onion powder, gold and silver wire raw materials. "Environmental protection is the trend of the town have been in the lead, the rectification be eliminated sooner or later." Wu Shaoliang said that five years ago he began to study how to deal with the coating waste gas.

Again with the Institute of environmental protection research and contact, and learn, improve, from non professionals to the present half of experts, Wu Shaoliang has invested about 2000000 yuan for the development of environmentally friendly energy conversion equipment.

October 2014, Wu Shaoliang's coating plant installed the first environmentally friendly energy conversion equipment, the value of 450 thousand yuan. "Prior to the equipment or a large investment, or high cost of operation, are not practical." Wu Shaoliang said, this equipment is only required upfront investment, because the energy can be recycled, the operating cost is almost zero. This is not in other parts of the country."

In the first device running 8 months later, the effect is satisfactory. In March this year, Wu Shaoliang installed second units, and now the entire plant 8 sets of coating equipment has 5 units have been to achieve the purification of waste gas, conversion.

"Before working in the workshop, the taste is particularly heavy, and sometimes eyes can not open." Yang Dejiang, who spent four years at the factory, said, "it's not the same now. Since it's a green machine, everyone is in a state of work."

Wu Shaoliang said, according to the present situation, technology and equipment have been mature, the next step is to please to demonstrate the feasibility of the environmental protection department and Zhejiang University, Zhejiang University of technology, Professor, once adopted, will the local promotion, "the whole Dongyang now has about 40 coating factory, more than 100 coating machine, I hope can achieve the exhaust gas purification and reuse."
