Turbulence inferior high-speed wet efficient electrostatic precipitator used for removing powdered coal and dust pollution

Abstract

The invention discloses a turbulence inferior high-speed wet efficient electrostatic precipitator used for removing powdered coal and dust pollution. The turbulence inferior high-speed wet efficient electrostatic precipitator comprises an inferior high-speed wet electrostatic precipitator body (2). A dusty gas inlet of the inferior high-speed wet electrostatic precipitator body (2) communicates with an outlet of a turbulence efficient washer (1) through a pipeline. A turbulent high-energy nozzle (7) communicating with a turbulent circulating pump (13) is arranged on the lower portion of the turbulence efficient washer (1) and is arranged vertically upwards, so that dusty gas entering the turbulence efficient washer (1) through a gas inlet (8) fiercely impact upon a reverse sprayed liquid column which is fed by the turbulent circulating pump (13) and sprayed out of the turbulent high-energy nozzle (7). Remaining dusty gas enters an anode dust collecting mechanism (4) of the inferior high-speed wet electrostatic precipitator (2) to be subjected to secondary dedusting, and the overall efficiency of the two times of dedusting is not lower than 99.86%. By adoption of the electrostatic precipitator provided by the invention, the dust content of a gas exhaust outlet can decline to below 5mg / Nm<3>.

Description

technical field [0001] The present invention relates to the field of environmental protection technology, in particular to a turbulent sub-high-speed wet electrostatic precipitator that can be applied in the field of dusty gas treatment technology, specifically a kind of dust collector that can effectively remove pollution factors such as pulverized coal, dust and aerosols. The turbulent sub-high-speed wet high-efficiency electrostatic precipitator. Background technique [0002] Since 2009, the state has gradually increased the emission standards for sulfur dioxide, acid mist and fine particulate matter in industries such as electric power, steel, non-ferrous metals, petrochemicals, and building materials. The discharge standards of various pollutants are more stringent. [0003] The original coal-fired system generally uses cloth bags or dry electrostatic precipitators to collect coal dust and other dust. The earlier pulverized coal and coal ash dust collection adopts bag...

AI Technical Summary

Problems solved by technology

A large amount of coal dust was not treated during the operation of the coal transportation system, and the depth of dust on site seriously exceeded the standard, which did not comply with environmental protection regulations and occupational health and environment regulations, and the equipment also had serious safety hazards

If the coal dust in the environment is not treated or treated adequately, it will cause great harm to the environmental sanitation and safety and the physical and mental health of the operators.
