Dust removal device for diffusion membrane processing

Abstract

This utility model discloses a dust removal device for diffusion membrane processing, including a dust collection box. An electrostatic eliminator is installed at the initial end of the dust collection box, and a diffusion membrane adsorption dust removal device is installed at the end of the dust collection box. This utility model uses a U-shaped adsorption tube to position the suction port on the upper and lower sides of the diffusion membrane, achieving comprehensive dust collection. The sucked-in exhaust gas is pre-filtered through a filter screen, filtering out large particulate impurities, which either adhere to the filter screen or fall into the collection tank. The user can flip the L-shaped limiting plate to release its restriction, allowing for removal and cleaning. By installing a water collection ring plate and atomizing nozzles inside the spray cylinder, the exhaust gas can be further dusted, ensuring that the gas is discharged indoors without affecting the surrounding environment or human health. Wastewater is collected in a collection box and can be easily poured out.
