Descrition of dust control for asphalt hot mix plant

Ⅰ General design plan

1, at present, the most popular pollutions caused by discharging of asphalt mixing plant could be divided into 3 sources, which are ,dust pollution from aggregate, smoke pollution from volatilization of high-temperature treated bitumen,noxious gas pollution caused by unqualified fuel.

Third, fuel pollution

Currently, asphalt mixing plant mainly used heavy oil, coal, natural gas as fuel. The heavy oil is usually blended, impurity content far beyond the standard, and many mixing plants even use fuel oil the composition of which is not clear, pungent smells make people dizzy. With improvements of burner technology, the increasingly wide range of fuel is available, but the fuel pollution caused by lack of standardization has become even more serious.

Coal dust pollution generated in the combustion process is also very serious, there is pulverized coal particle escaping in the crushing process, around the coal asphalt mixing equipment is covered with a layer of pulverized coal.

Therefore, only when the asphalt mixing plant uses green energy natural gas as the fuel the pollution problems of fuel can be solved fundamentally. September 30, 2015, Shanghai has completed the statistical fuel burner, and in terms of tons of steam, all replaced to gas burner with the subsidies of the government.
