Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically providing a dual-fan wet dust removal device. Background Technology

[0002] Dust is generated during mining operations, tunnel excavation, and coal transportation, posing a threat to workers' health and safety and impacting the lifespan of production equipment. To address dust pollution, appropriate dust removal equipment is needed to meet the needs of mine production. Wet scrubbers for mining are widely used environmental protection devices in industries such as mining, metallurgy, and chemicals. The main principle of wet scrubbers is the formation of a water film, which causes dust particles in the gas to be deposited and adsorbed, thereby achieving dust removal.

[0003] Currently available wet dust collectors can be used for dust removal in mine production, but they have the following problems: 1) Existing wet dust collectors usually have fixed spray volume and fixed exhaust volume, which reduces their flexibility and easily leads to water waste; 2) The shells of existing wet dust collectors are mostly integral structures, which makes the shells heavy and inconvenient to handle manually; 3) The connection stability of the components in traditional wet dust collectors is limited, resulting in high maintenance costs.

[0004] In conclusion, designing a wet dust collection device that offers excellent dust removal performance, saves water resources, reduces energy consumption and improves reliability, and is easy to transport is an urgent problem that needs to be solved. Utility Model Content
