What is the principle of the work of dust removal equipment in industry

The working principle of industrial dust removal equipment, is to "force" as its principle, such as suction, wind, pressure and so on, according to the size of the force, classification, industrial dust precipitator equipment manufacturers designed size is not the same, but the design of the dedusting design work is the preparation principle dust separation and decomposition of gas, clean air is exhausted.
The classification of industrial dust removal equipment can be roughly divided into: bag filter, wet dust collector, single unit dust collector, cyclone dust collector, electrostatic precipitator, polishing and dust removal bench, pulse filter cartridge filter, exhaust gas treatment, welding smoke treatment equipment and so on.
The principle of dust removal equipment work can be divided into four categories
1: mechanical dedusting equipment
The mechanical dedusting equipment is divided into three kinds, which are gravity dust remover, cyclone dust collector and inertial duster.
The principle of gravity dust collector is to remove dust by gravity. Gravity is the earth's gravity, and the dust is separated from the dust when it is settling.
The cyclone relies on centrifugal force, and the centripetal separation force is applied to the circular moving object, which is based on the principle of mass gain and fast rotation in the rotation process.
Inertial dust collector is to use the inertia and inertia of dust, which is the force reflecting the state of motion, and is changed by the force of the outside state, so that the inertial object will change its motion state than the object with large inertia.
Two: the working principle of the electrostatic precipitator
The working process of the electrostatic precipitator is divided into four stages: gas ionization, dust charge, dust settlement, and ash cleaning.
Let the gas ionization electrode corona discharge, gas ionization, positive ions generated a large number of free electrons, electric dust charge local field space, free electrons and negative ions to dust collide together, let the dust settling in charged dust after a certain period of time to reach the surface dust, released charge deposition to the above, the dust accumulation to a certain thickness, loaded with dust cleaning device cleaning down, covered with ash to the following.
Three: the working principle of the bag dust removal equipment
When the gas with dust is sucked into the bag, the bag than large particles of dust due to the large volume than the bag, by the effect of gravity sedimentation was or is because the role of inertia is the live fiber bag, the collision of small particles and dust bag than the bag, the bag is attached to the surface of the fiber on the surface of the filter bag, bag dust removal equipment of the injection system was blowing, dust fall into the hopper.
Four: the working principle of the wet dust collector
In the wet dust collector, the water in the box is contacted with the dust and gas, and the water will collide, diffuse and coagulate with the dust. Then, the large particles will be formed due to the condensation of water, and eventually they will be carried away by the water. The smaller the water droplets in the wet dust catcher, the more water droplets, the more opportunities to contact dust, and the higher the efficiency of collision, diffusion and condensation.
More dust treatment: a workshop dust control scheme
The main performance indicators of the dust removal equipment in the industry also include the design load, dust removal efficiency, pressure loss and gas volume of the dust removal plant. The principle of dust removal equipment in the industry is very similar. Just like the beginning of the article, all of them are "force" as the starting point, so the measurement and calculation of the size of the wind power by the duster manufacturer has a very important influence.
