Products description
The following is about the working principle of Anti-static powder coating dust cartridge filter element (anti-static powder coating dust cartridge filter element) :
1. ** Electrostatic adsorption principle **
- ** Charge generation and effect ** : In industrial production, especially in the powder coating, chemical, cement and other industries, dust particles will carry static electricity in the process of generation and transmission. When the dust airflow with static electricity passes through the filter element, the charged dust is more easily adsorbed to the surface of the filter element due to the attractive effect of static electricity. This is because the filter element is usually made of special conductive materials or treated to make it conductive, which can release the static electricity of the dust, so that the dust is firmly adsorbed on the filter element [^1^].
- ** Enhanced filtration effect ** : This electrostatic adsorption effect enhances the ability of the filter element to capture dust. Compared with the ordinary filter element, it can more effectively filter small particles of dust and improve the filtration efficiency, especially for dust particles with small particle size.
2. ** Physical filtering principle **
- ** Screening effect ** : The filter material of the filter element has a certain pore structure. When the dust-containing air flow passes through the filter element, the dust particles that are larger than the pore size of the filter element will be intercepted on the surface of the filter element and cannot pass through the filter element, so as to achieve gas-solid separation. This is the most basic filtration principle, similar to a sieve sieving particles of different sizes [^1^].
- ** Inertial collision and interception ** : When the air flow passes through the fiber layer of the filter element, the dust particles may collide with the fiber due to their own inertial effect and be intercepted down. At the same time, some smaller dust particles may follow the airflow to bypass the fiber under the action of the air flow, but in the process of bypassing the fiber, due to the close distance from the fiber, they will be affected by the van der Waals force on the fiber surface and be adsorbed on the fiber, so as to achieve filtration.
3. ** Cleaning principle of regeneration **
- ** Pulse blowing dust cleaning ** : with the process of filtration, the dust adsorbed on the surface of the filter element gradually increases, which will lead to the rise of filtration resistance and affect the filtration effect. Therefore, the filter element needs to be cleaned regularly. The common way to clean dust is pulse blowing, which releases the high-pressure air flow instantly, so that the filter element expands and contracts rapidly, and the dust attached to the surface of the filter element shakes down and falls into the ash bucket. In this way, the filter element can maintain good filtration performance and prolong the service life of the filter element [^1^].
- ** Reverse blowing dust ** : Another way of dust cleaning is reverse blowing dust, that is, blowing air from the back of the filter element to the front, so that the dust on the surface of the filter element falls off. This method is relatively mild and suitable for some occasions with less damage to the filter element.
In summary, Anti-static powder coating dust cartridge filter element (anti-static powder coating dust cartridge filter element) can effectively remove dust particles in industrial production and keep the air clean through the synergism of the above working principles. Ensure the safety and stability of the production environment.
