Problems solved by technology

Due to the negative pressure in the water curtain cavity, the mixed gas of dust and water is discharged into the atmosphere instantly under the action of the fan, the dust does not fall, the dust removal effect is poor, and the dust content in the discharged gas is relatively high; this type The water consumption of the dust collector reaches 3.6 cubic meters per hour, resulting in water waste and secondary sewage treatment, and the material of the water curtain dust collector shell is easy to corrode, not strong enough, easy to crack and deform, and requires a lot of maintenance

Embodiment Construction

[0018] Attached below figure 2 , the specific implementation of the dust removal device provided by the embodiment of the present invention will be described in detail.

[0019] The embodiment of the present invention provides a dust removal device, the dust removal device is composed of a closed pool 25, a closed air passage, an air inlet pipe 21, an air outlet pipe 27, a sewage outlet 23 and a fan 22, and the two ends of the closed air passage are respectively connected to the closed Type pool 25 is connected with fan 22, air inlet pipe 21 is connected with fan 22, the upper part of the closed pool is connected with air outlet pipe 27, and the lower part of the closed pool is connected with sewage outlet 23; On the water surface of the closed pool 25, the water body forms a surge in the closed pool 25, so that the dust contacts with the surge and is absorbed by the water. The gas after dust removal is discharged through the air outlet pipe 27, and the fallen dust forms mudd...

Abstract

The invention discloses a dust removal device. The dust removal device is used for solving problems in dust removal of dust-containing gas of a dressing plant. The dust removal device provided by an embodiment of the invention consists of a closed water tank, a closed air channel, an air inlet pipe, an air outlet pipe, a sewage discharge outlet and a fan. According to the invention, dust-containing gas is sucked in through the fan and is blown over the water surface of the closed water tank in a positive pressure mode; water forms surges in the closed water tank, and dust makes contact with the surges and is adsorbed by water; and the gas obtained after dust removal is discharged through the air outlet pipe, and falling dust forms muddy water which is to be discharged from the sewage discharge outlet. The dust removal device is good in dust falling effect, and discharged gas only has water mist without dust.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust removal device suitable for mineral processing plants. Background technique [0002] The dust removal equipment in mine concentrators generally adopts heavy-duty anti-corrosion dust collectors. The working principle of this type of dust collector is to use the centrifugal fan installed on the outlet side of the water curtain dust collector 15 to generate a negative pressure of 12, so that the dusty air flows from the inlet The tuyere 14 enters the cavity of the water curtain dust collector 15, and a sprinkler 16 is installed on the upper part of the cavity, and a plurality of inclined plates 17 are installed oppositely from top to bottom to form multiple water curtains, thereby increasing the mixing area of ​​water and dust; The air after the dedusting enters the air duct 18, and is extracted by the centrifugal fan 12, and is discharged from the exhaust duct 11, and t...
