Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial dust removal, in particular to a wet dust removal device. Background Art
[0002] Since humans entered the industrial society, people's demand for energy materials in mines has been increasing. While mineral mining brings rich mineral resources, it is also a direct factor that induces geological disasters and pollutes the environment. The most prominent geological disaster is surface subsidence. Mine filling is the main means of controlling mining subsidence. During the mine filling process, the preparation of the filling paste plays a key role in the engineering quality of mine filling. During the mixing and preparation of the paste, the cement dust rises with a large amount of water vapor. The use of bag-type dust collectors can easily cause the dust bags to be solidified and compacted by cement, resulting in poor dust removal effect. In actual filling projects, wet dust removal devices are usually used for treatment and recycling.
[0003] However, the wet dust removal device in the prior art absorbs external impurities into the dust removal chamber through a fan, and then the sprayer inside the dust removal chamber generates water vapor to condense the impurities, and the condensed water droplets slide from the dust removal chamber to the bottom, thereby achieving the technical effect of dust removal. When this technology is used in the working environment of preparing filling paste, the fan will cause a small amount of water vapor condensed impurities to escape through the gaps inside the dust removal chamber, thereby forming secondary environmental pollution. In more serious cases, these impurities form a hardened structure inside the device, reducing the service life of the wet dust removal device. Utility Model Content

Specifically, the secondary spray structure arranged above the dust cover starts to start, and the external dust and impurities located in the dust cover condense with the water vapor sprayed by the secondary spray structure, and then fall to the bottom of the wet dust removal device under the action of gravity. At the same time, a large amount of air flowing into the fan duct is discharged through the exhaust hole, and a large amount of water vapor generated by the first spray structure and the second spray structure is finally collected at the bottom of this device through the first through hole for discharge.

[0014] 1. The fan duct passes through the secondary dust removal structure and enters the dust removal chamber. When the fan is turned on, the external impurities and dust can enter the dust removal cover through the fan duct.
