Principle of industrial dust removal equipment

Industrial dust removal equipment, also known as industrial dust collector, can separate industrial dust from flue gas produced by industrial production. The performance of different industrial dust removal equipment is definitely different. According to the amount of gas that can be handled, the resistance loss of gas passing through industrial dust removal equipment and the dust removal efficiency, the sales volume of dust removal can be calculated. As for the price, operation and maintenance cost, service life and operation and management difficulty of industrial dust removal equipment, it also has a great relationship with performance, and the principle of industrial dust removal equipment is the foundation. Next, I will introduce the principle of industrial dust removal equipment to you.

Principle of industrial dust removal equipment;

1. Bio-nano-membrane dust suppression: Bio-nano-membrane dust suppression technology, which is a double ionospheric membrane with nano-scale spacing, can maximize the ductility of water molecules and has strong charge adsorption; Spraying biological nano-film on the surface of materials can attract and gather small particles of dust, and make it aggregate into large particles of dust, thus increasing its own weight and settling; The highest dust removal rate of this technology can reach above 99%, and the average operating cost is 0.05~0.5 yuan/ton.

2. Cloud dust suppression: Cloud dust suppression technology produces 1μm~ 100μm ultrafine dry fog through high-pressure ion atomization and ultrasonic atomization; Ultra-fine dry mist particles are fine, which fully increases the contact area with dust particles, and the water mist particles collide with dust particles to form agglomerates, which become larger and heavier until they finally settle naturally, thus achieving the purpose of eliminating dust; 30%~40% of the generated dry fog particles are below 2.5μm, which has obvious prevention and control effect on atmospheric fine particle pollution.

3. Wet dust collection: Wet dust collection technology absorbs the air attached with dust through pressure drop, and removes dust under the dual effects of centrifugal force and mixing of water and dust gas; Unique impeller and other key designs can provide higher dust removal efficiency. Suitable for the production, processing, transportation, loading and unloading of bulk materials, such as mines, buildings, quarries, yards, ports, thermal power plants, steel plants, garbage recycling and other places.

4. Bag dust removal: The dust collector is mainly composed of ash hopper, filter chamber, clean air chamber, bracket, poppet valve, injection dust removal device, etc. When working, dusty gas enters the ash hopper from the air duct. Large particles of dust directly fall into the bottom of the ash hopper, and smaller dust enters the filter chamber with the turn of airflow, blocking the outer surface of the filter bag. The purified flue gas enters the cloth bag, enters the air outlet through the cloth bag mouth and the clean room, and is discharged from the air outlet. With the continuous filtration, the dust on the outer surface of the filter bag increases, and the resistance of the equipment increases accordingly. When the equipment resistance rises to a certain value, dust removal operation should be carried out to remove the dust on the surface of the filter bag.

5. Electrostatic dust removal: a gas dust removal method. Dust-containing gas is electrically separated when passing through a high-voltage electrostatic field, and dust particles are negatively charged after combining with negative ions, and then tend to discharge and deposit on the anode surface. It is used to purify gas or recover useful dust particles in metallurgy, chemistry and other industries. A dust collection method uses electrostatic field to ionize gas, so that dust particles are charged and adsorbed on electrodes. In the strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are adsorbed by the negative electrode to the positive electrode and collected. It is usually used in coal-fired factories and power stations to collect coal ash and dust in flue gas. Used in metallurgy to collect oxides such as tin, zinc, lead and aluminum.

The above is the content of the principle of industrial dust collector equipment. Industrial dust collector equipment is used in many industrial places and is an essential equipment in industrial production. However, the operating pressure of industrial dust collector equipment is not fixed, which is generally related to the static pressure value of devices and fans before and after industrial dust collector equipment. In addition, it also has a great relationship with the installation location. The design withstand voltage of industrial dust collector equipment has a great influence on its performance, which can also be understood in the Principle of Industrial Dust Collector Equipment.
