Dust removal series

Dust removal equipment refers to devices that separate dust from flue gas, also known as dust collectors or dust removal devices.Automatic vacuum feeding machineIt is to use the underground dedusting water pipe and air pressure pipe to add certain additives in the water, introduce air pressure, complete a series of process flows through special equipment, generate foam, and spray it to the dust source through the distributor and sprinkler support components.

Our country's electrostatic precipitator technology has developed maturely, and the main technical level has entered the international advanced level.

1. Industry technical level and characteristics

The technical level and characteristics of this industry mainly lie in the following aspects:

(1) Biological nanofilm dust suppression is included in the "Compilation of Advanced Technologies for Air Pollution Prevention and Control" released by the Ministry of Science and Technology and the Ministry of Environmental Protection

Biological nanofilm dust suppression technology, which is a double ionospheric membrane with a layer spacing of nanometer level, can maximize the extensibility of water molecules and has strong charge adsorption properties; Spraying biological nanofilm onto the surface of materials can attract and agglomerate small particles of dust, causing them to aggregate into large particulate dust particles that increase in weight and settle.

(2) Cloud and fog dust suppression is included in the "Compilation of Advanced Technologies for Air Pollution Prevention and Control" released by the Ministry of Science and Technology and the Ministry of Environmental Protection

Cloud and mist dust suppression technology is achieved through high-pressure ion atomization and ultrasonic atomization, which can generate ultrafine dry mist ranging from 1 μ m to 100 μ m; The ultra-fine dry mist particles are fine and dense, fully increasing the contact area with dust particles. The water mist particles collide and condense with the dust particles, forming agglomerates. The agglomerates continue to grow larger and heavier until they naturally settle, achieving the goal of eliminating dust.

(3) Wet dust collection is included in the "Compilation of Advanced Technologies for Air Pollution Prevention and Control" released by the Ministry of Science and Technology and the Ministry of Environmental Protection

Wet dust collection technology absorbs air with attached dust through pressure drop, and removes dust under the dual effects of centrifugal force and the mixture of water and dust gas; The unique impeller and other key designs can provide higher dust removal efficiency.

(4) The electrostatic precipitator technology is in the mature application stage, but the emission concentration is difficult to meet the new control standard requirements
