Technical Field
[0001] The utility model relates to the field of dust removal devices, in particular to a wet dust removal device. Background Art
[0002] A wet dust removal device is a dust removal equipment that uses water as a medium and is mainly used for purifying dust-containing gases. There are many production and processing methods in industry that generate dust or waste gas, such as: grinding, polishing or other operations that generate splashing and high-temperature dust; die-casting machines that generate coolant steam or aerosol; casting that generates wet or sticky dust, and ceramic or glass production and processing. Dust and waste gas will pollute the surrounding environment. Therefore, it is often necessary to be treated by a dust collector before being discharged. The wet dust removal device has a high dust removal efficiency, especially has a good trapping effect on fine dust and toxic and harmful dust.
[0003] The dust removal process of the wet dust removal device: The smoke and dust generated by welding are transported into the wet dust collector under the action of the negative pressure of the fan for filtration, and the dust-containing air flow enters the dust removal cylinder through an air pump. The washing liquid is injected into the dust removal cylinder through a nozzle group by a water pump. By using the centrifugal force inside the scrubber, the washing liquid containing pollutants is separated from the air flow. The muddy precipitate captured by water settles into the circulation water tank together with water; the purified waste gas is discharged into the atmosphere through the chimney via the fan.
[0004] The existing wet dust removal device has a low purification rate of smoke and dust, poor dust removal effect, and it is not easy to remove relatively fine smoke and dust, resulting in incomplete dust removal and requiring secondary purification before discharge. Summary of the Utility Model
