How to choose dust removal equipment?

Industrial manufacturing has accelerated the process of urbanization in China, making people's lives more convenient. However, while the economy is developing rapidly, the atmospheric pollutants emitted by industrial manufacturing cause great harm to the surrounding environment and seriously affect the physical health of factory workers. In order to reduce air pollution, some factories have equipped dust removal equipment, and the performance and efficiency of dust removal equipment are key factors in determining the degree of harm of atmospheric pollutants to the environment and workers. So, how should we make a choice when facing a wide variety of dust removal equipment in the market with significant price differences?

The editor of Qingdao dust removal equipment has collected and organized relevant knowledge about dust removal, which is divided into four categories according to the mechanism of capturing and separating dust particles. Below, we will introduce in detail the differences between the four types of dust removal methods,

1、 Mechanical dust removal equipment

According to whether the force acting on the dust gas inside the dust removal equipment is gravity, inertial force, or centrifugal force, these types of dust collectors can be further divided into:

(1) Gravity dust removal device, also known as gravity settling chamber.

(2) Inertial dust removal device, also known as inertial dust collector.

(3) Centrifugal dust removal device, also known as cyclone dust collector.

Suitable for airflow with high dust concentration and high particle strength. Widely used in situations with low dust removal requirements or as a pre dust collector for high-efficiency dust removal devices.

2、 Filter type dust removal equipment

The dust containing gas and the filtering medium achieve gas-solid separation through inertial collision, diffusion, interception, screening, and other actions. This dust removal device is called a filtering dust removal equipment. According to the different filtering media and structural forms used, this type of dust collector can be further divided into:

(1) Bag filter dust removal device, commonly referred to as bag filter.

(2) Particle layer dust removal device.

Suitable for dry powder industries such as flour, coal powder, sand powder, and aluminum powder, but not suitable for dust with strong adhesion and moisture content.

3、 Electrostatic dust removal equipment

According to the principle of positive and negative charge attraction, the exhaust gas containing particles is ionized under a high-voltage electric field, causing the particles to carry charges. When the charged particles enter the electrostatic dust collection area, they are adsorbed on the electrostatic plate, completing the electrostatic purification process.

Suitable for industries such as metal processing, aviation, shipbuilding, automobile manufacturing, textile printing and dyeing, mechanical processing, die-casting, etc. Its advantage is that it has no consumables in the later stage and can be repeatedly cleaned and used. Currently, it has a wide range of applications.

4、 Wet dust removal equipment

Dust removal equipment that uses water or other liquids as dust collection media is called wet dust removal equipment. According to the level of energy consumption of the equipment, it can be further divided into:

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

(2) High energy wet dust collectors, such as Venturi humidifiers.
