Technical Field

[0001] The utility model belongs to the technical field of air filtration, and in particular relates to a novel water curtain type liquid tank type air filter. Background Art

[0002] Water curtain dust collector is commonly known as "water dust collector". It is a device that brings dust-laden gas into close contact with liquid, and uses the inertial collision of water droplets and particles or the full mixing of water and dust and other effects to capture particles or enlarge particles or retain them in a fixed container to achieve the effect of separating water and dust.

[0003] Existing water curtain dust collectors are widely used in dust-polluted workshops such as cement plant manufacturing workshops. However, the filter chips of the air filter will cause dust to accumulate on the filter net after use, making it inconvenient to clean the filter net. If not cleaned in time, it will cause secondary pollution and affect the subsequent filtration effect.

[0004] To this end, we proposed a new type of water curtain liquid tank air filter to solve the above problems. Utility Model Content
