How much do you know about the classification of dust collectors

According to the principle of function, the dust collector can be divided into the following types:
 
Dry mechanical dust collector mainly refers to the dust removal equipment designed for the application of dust inertia and gravity, such as high-concentration dust collectors such as settling chambers, inert dust collectors, and cyclone dust collectors, etc., mainly for the separation of high-concentration coarse-grained dust Or concentrated and used.

Wet dust collectors rely on hydraulic affinity to separate and capture dust particles, such as spray towers, scrubbers, impact dust collectors, venturi tubes, etc. Dust and gas occasions are often used. For coarser, hydrophilic dust, the separation efficiency is higher than that of dry mechanical dust collectors.

The granular layer dust collector uses the accumulation layer of granular materials of different particle sizes as the filter material to block and filter the dust contained in the gas solution. It is mainly used in the dust exhaust point in the production process of building materials, metallurgy, etc., and it is often used to filter dusty flue gas with high concentration, coarse particles and high temperature.

Bag type dust collector, the filter is a dust removal device with fiber woven fabric or filling layer as the filter medium. It has a wide range of uses, forms, dust removal air volume scale and efficiency, and is mainly used to capture fine dust. In some places, it is applied on the exhaust dust removal system and on the air intake system. In recent years, due to the continuous development of new filter materials, the development of fiber filtration technology has also accelerated, new products continue to appear, and the application field is also increasingly broadened.

Electrostatic precipitator The dust collector introduces the dust-laden airflow into the electrostatic field. Under the action of the high-voltage electric field, the gas is ionized to generate electrons and positive ions. They move to the positive and negative poles respectively. When the dust particles flow through the working electric field, the negative Charges are moved at a certain speed to the settling plate with the opposite sign of their negative charge, and settle down there, so as to escape from the air flow and be collected in the electrostatic precipitator. This kind of dust collector has high dust removal efficiency, low resistance, and convenient maintenance and management. It has the same effect as the bag filter in capturing fine dust particles.
