The demand for wet electrostatic precipitators in key polluting industries will continue to increase

The filter wind speed of the wet electrostatic precipitator is too high, which is the main reason for the damage of the dust filter bag. In recent years, some units have blindly reduced equipment costs and increased profits. When designing bag filters, they have increased the filtration wind speed. There is no obvious response from users in a short period of time, but the service life of filter bags has been greatly shortened. In this way, instead of saving money to customers, it brings a very large economic burden and wastes time.

In addition, with the continuous increase of SCR denitrification devices in power plants, SCR catalysts greatly increase the concentration of SO3 in flue gas, while the removal efficiency of SO3 by wet desulfurization is low, resulting in the secondary formation of SO3 escaped from wet desulfurization. PM2.5 particles, mixed in wet desulfurization flue gas, make "white smoke" into "yellow smoke".

From the perspective of the application of electrostatic precipitators, according to the "2013-2017 China Dust Removal Equipment Manufacturing Industry Production and Sales Demand and Investment Forecast Analysis Report" released by Qianzhan Industry Research Institute, in the United States, bag type dust collectors are currently the most important in the field of power plant boiler flue gas treatment. It occupies more than 40% of the share, and more than 90% of the large dry-process cement kiln tails use bag filters; in Europe, bag filters account for nearly 50% of power plant boilers; in Australia, more than 80% of thermal power plants are currently All adopt bag type dust removal. In my country, the market share of bag filter in the steel and non-ferrous industries has reached more than 90%, and the market share in the cement industry has reached more than 80%.

From the perspective of the sources of air pollution in my country, according to relevant research conducted by the Ministry of Environmental Protection, the main sources of air pollution in my country can be divided into productive pollution, living pollution and transportation pollution, among which productive pollution is the most important. Among the productive pollution, thermal power plants, iron and steel plants, petrochemical plants, and cement plants are the most serious air pollution.

Therefore, as the country's emphasis on environmental protection continues to increase and the intensity of air pollution control continues to increase, we believe that the demand for dust removal equipment in key air pollution industries will continue to increase, and bag dust removal equipment will fully benefit from market demand. growth of!
