How to choose dust removal equipment

Industrial manufacturing industry has accelerated the process of urbanization in China and made people's life more convenient. However, with the rapid development of economy, the air pollutants emitted by industrial manufacturing industry have caused great harm to the surrounding environment and seriously affected the health of factory workers,In order to reduce air pollution, some factories are equipped with dust removal equipment, and the performance and efficiency of dust removal equipment is the key to the degree of harm to the environment and operators of air pollutants. Then, let's introduce how to choose dust removal equipment!

Selection of dust removal equipment

How to choose the dust removal equipment with a wide variety of prices on the market? Now the data on dust removal are collected and sorted out, which can be divided into the following four categories:

1. mechanical dust removal equipment

Depending on whether the force is gravity, inertial force or centrifugal force, the dust collector can be divided:

(1) gravity dust removal device, namely gravity settling chamber.

(2) inertial medium dust collector, that is, inertial dust collector.

(3) centrifugal dust removal device, namely cyclone dust collector.

It is suitable for airflow with high dust concentration and large particle strength. It can be widely used in occasions where the level of dust removal technology is not high or as a pre-filter for a dust removal device.

2. filter type dust removal equipment

Dust-containing gas and filter media achieve gas-solid separation through inertial collision, diffusion, interception, shielding, etc. This dust removal device is called filter dust removal equipment. According to the different filter media and structural forms used, this kind of dust collector can be divided:

(1) bag filter, commonly known as bag filter.

(2) particle layer dust removal device.

Suitable for flour, coal powder, sand powder, aluminum powder and other dry powder industry, not suitable for strong adhesion, wet dust.

3. electrostatic dust removal equipment

According to the principle of positive and negative attraction of different charges, the exhaust gas with particulate matter is ionized under high-voltage electric field to charge the particulate matter. When the particulate matter with a charge can enter the electrostatic dust collection area of the system, the particulate matter is adsorbed on the electrostatic plate to complete the purification process of electrostatic action.

It is suitable for metal processing, aviation, transportation, automobile manufacturing, textile printing and dyeing, mechanical processing, die casting and other industries. Its advantage is that there are no consumables in the later stage, and it can be cleaned and used repeatedly. It is currently widely used.

4. wet dust removal equipment

Water or other liquids can be used as dust trapping medium dust removal technology equipment management called wet dust removal system equipment. According to the energy consumption of teaching equipment, it can be divided:

(1) Low energy consumption wet scrubbers, such as hollow spray towers, water film scrubbers, etc.

(2) High-energy wet dust collector, such as Venturi humidifier.

The above is how to choose the dust removal equipment, if you need to know more, you can contact us at any time! Our company has many years of experience and looks forward to your joining at any time!
