1.Intercept and dust removal.
Interception and dust removal is to use the interception effect of the multi-layer plastic sintered plate filter element of the plastic sintered plate dust collector to intercept the large particles in the air flow, so as to achieve the purpose of dust removal. This method is mainly suitable for removing large particles in the gas stream, such as dust, soot, etc. In the interception process, the special structure of the plastic sintered plate filter element can effectively increase the contact area between the airflow and the filter element and improve the interception effect.
2.Inertial collision dust removal.
Inertial collision dust removal is to use the inertia of the air flow to make the particles in the air flow collide with the plastic sintered plate filter element, so as to achieve the purpose of dust removal. This method is mainly suitable for removing moderate particulate matter such as oil mist, aerosols, etc. from the gas stream. In the process of inertial collision, the velocity and direction of the airflow will affect the trajectory of the particles, so it is necessary to adjust the speed and direction of the airflow according to the actual situation to improve the dust removal effect.
3.Diffusion, adhesion and dust removal.
Diffusion adhesion dust removal is the use of the diffusion of particles in the air flow to make the particles adhere to the surface of the sintered plate filter element, so as to achieve the purpose of dust removal. This method is mainly suitable for removing fine particles such as aerosols, bacteria, etc. from the gas stream. In the process of diffusion adhesion, factors such as particle size, density and adhesion of particles will affect its adhesion effect, so it is necessary to select the appropriate filter material and structure according to the actual situation to improve the dust removal effect.
4.Charge adsorption and dust removal.
Charge adsorption dust removal is to use the charged nature of particulate matter, so that the charged particulate matter is adsorbed on the surface of the filter element of the plastic sintered plate, so as to achieve the purpose of dust removal. This method is mainly suitable for removing charged particulate matter from the gas stream, such as soot, metal dust, etc. In the charge adsorption process, factors such as the electric field strength and the charge amount of the particles will affect the adsorption effect, so it is necessary to adjust the electric field strength and the charge of the particles according to the actual situation to improve the dust removal effect.
In short, there are many dust removal methods for plastic sintered plate dust collectors, and it is necessary to choose the appropriate dust removal method according to the actual situation. In practical applications, a combination of dust collection methods can be used to improve the dust removal effect. For example, interception and inertial collision dust can be used in combination to remove large and medium particulate matter from the gas stream; Alternatively, diffusion adhesion dust removal and charge adsorption dust removal can be used in combination to remove fine and charged particles from the gas stream. At the same time, it is also necessary to pay attention to the replacement cycle and maintenance of the plastic sintered plate filter element to ensure the long-term stable operation of the dust collector.
