Technical Field

The invention relates to the technical field of dust collectors, in particular to a high-efficiency energy-saving vortex spraying type electric bag composite dust collector for high-pollution industry.

Background

A dust collector or dust removing equipment, which is equipment for separating dust from flue gas. The performance is expressed in terms of the amount of gas that can be handled, the drag loss of the gas as it passes through the precipitator, and the efficiency of dust removal. Meanwhile, the price, the operation and maintenance cost, the service life and the difficulty of operation management of the dust remover are also important factors considering the performance of the dust remover. Dust collectors are common facilities in boilers and industrial production. Especially for the treatment of highly polluting industrial boilers or furnaces, from the point of view of dust removal by ventilation, the dusts are also called small solid particles, in particular dusts harmful to the human body, which, when present in the air in a floating state for a long time, present a dispersed system, also called aerosol, in which the air is the dispersion medium and the solid particles are the dispersed phase. A dust separator is a device that separates such small solid particles from an aerosol. According to the principle of action, the dust collector can be divided into a dry mechanical dust collector, a wet dust collector, a particle layer dust collector, a bag type dust collector, an electric dust collector and the like.

In modern industrial development, flue gas discharged by kilns in the industries of thermal power, metallurgy, building materials, sugar manufacturing, chemical engineering and the like has a large amount of dust, and can be discharged into the atmosphere after being purified, so that industrial civilization and urban development can create huge wealth for human beings, and simultaneously, billions of tons of waste gas and waste are discharged into the atmosphere, and the atmospheric space on which the human beings rely for survival becomes an aerial garbage storehouse and a toxic gas storehouse. Therefore, when harmful gases and pollutants reach a certain concentration in the atmosphere, great disasters are brought to human beings and the environment. In recent years, the wide attention of the public is caused in the wide range of haze weather in China, and the haze weather becomes a current environmental hotspot problem. China is in the stage of rapid development of urban chemical industrialization, and the type of atmospheric pollution is deeply changed. The pollution problems of the traditional sulfur dioxide (SO 2), suspended matters (TSP)/inhalable particles (PM 10) and the like are not solved, the emission of fine particles (PM 2.5), nitrogen oxides (NOx), volatile Organic Compounds (VOCs), ammonia nitrogen (NH 3) and the like is obviously increased, and the air pollution is caused

The situation is becoming more severe. As a new industry, the dust collector industry in China faces a golden period of economic high-speed development and a golden period of urgent need of pollution control. Over decades of development, the precipitator industry has developed a range of scales and capabilities. Therefore, how to effectively treat the dust discharged by industrial and mining enterprises, reduce air pollutants as much as possible, and the high-efficiency and energy-saving composite dust remover is a difficult problem to be solved urgently.
