Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a water curtain dust removal device. Background Technology

[0002] Dust is generated during the loading and unloading of powder materials, requiring dust removal equipment for treatment. Currently, dust removal equipment includes bag filters, cartridge filters, cyclone collectors, electrostatic precipitators, pulse jet collectors, and water curtain dust collectors. Compared to other dust removal devices, water curtain dust collectors have advantages such as simple structure, small footprint, convenient operation and maintenance, and high purification efficiency. They can handle high-temperature and high-humidity airflows and have a low probability of fire or explosion.

[0003] Water curtain dust collectors utilize the properties of a water curtain to capture and settle airborne particulate matter and dust through the inertial collision of water droplets and particles, or through the thorough mixing of water droplets and dust, thereby purifying the air. Water curtain dust collectors can effectively remove liquid or solid particles with diameters of 0.1-20 micrometers from the airflow, and can also remove some gaseous pollutants. However, existing water curtain dust collectors do not mix water droplets and dust sufficiently, resulting in poor dust removal efficiency. Utility Model Content
