At present, China's annual coal consumption of thermal power generation is about 1 billion tons, and the smoke emission of power plants is about 4 million tons, accounting for 35% of the national industrial smoke emission. Among them, the emission of fine particles (less than 10 μ m) is more than 3 million tons, which seriously endangers human health.
Cement
China's cement industry discharges more than 10 million tons of dust into the atmosphere every year. If it is not recycled, the total dust emission in the process of cement production will exceed 5% of the output (calculated by cement clinker). The development trend of environmental protection standards of cement industry is increasing year by year
Iron and Steel
With the improvement of environmental protection standards, the application of sintering machine bag, blast furnace gas dry dedusting and blast furnace gas residual pressure power generation (TNT) is more and more widely. The following is a brief working condition and filter material selection of common sections
Waste Incineration
According to the national regulations, bag filter must be used for waste incineration tail gas treatment, but its working condition is complex and changeable, which is prone to various damages and even failure in practical application. We suggest that customers give priority to 100% PTFE to adapt to the following harsh working conditions
Asphalt Industry
Flue gas characteristics of the system: 1. The main flue gas is the flue gas after burning heavy oil or diesel oil, and the dust, moisture and asphalt flue gas during the drying process of sand and stone. 2. Due to the large dust particles at the air outlet, one-stage inertial dust removal must be added, which not only protects the filter bag from the impact of Mars, but also recycles the recovered fine powder.
