Dust removal device for trash combustion

Abstract

The invention relates to the technical field of dust removal auxiliary devices, in particular to a dust removal device for trash combustion. The effective coverage of water spray on smoke dust is improved, and therefore the dust removal effect is improved, and practicability is improved; the flowing speed of the smoke dust can be evenly distributed, the smoke dust and water spray are prevented from being discharged out of an air outlet pipe under the unstable wind speed, and environmental friendliness is improved; meanwhile, generated sewage can be processed, water resources are saved, and usereliability is improved. The dust removal device comprises a dust removal tower, a water tank, a spraying pump, an air inlet pipe, an induced draft fan, an air outlet pipe, an axial flow fan, a supporting plate, two spraying pipes, a communication pipe, a rotary motor, a ball bearing, a driven gear, a plurality of spraying nozzles, a rotating shaft, a driving gear, two sealing covers, two insertion pipes, a plurality of flow guide plates and a grating plate. The flow guide plates are each of a rhombic structure. The grating plate is evenly provided with multiple groups of wind uniformizing holes. The dust removal device further comprises a sewage pipe, a partition plate, a filter tank, a filtering device and a backflow pipe.

Description

technical field [0001] The invention relates to the technical field of dust removal attachments, in particular to a dust removal device for garbage incineration. Background technique [0002] As we all know, the dust removal device for garbage incineration is an auxiliary device used in garbage treatment plants to process the smoke generated when incinerating non-recyclable garbage and improve environmental protection. It has been widely used in the fields of garbage treatment and environmental protection. The existing dedusting device used for garbage incineration comprises a dedusting tower, a water tank and a spray pump, the inside of the dedusting tower is provided with a working chamber, the top of the working chamber is provided with a spraying pipe, and the bottom of the spraying pipe is connected with multiple The left end of the dust removal tower is provided with an air inlet pipe, and an induced draft fan is arranged at the air inlet pipe. The top of the dust remo...

[0002] As we all know, the dust removal device for garbage incineration is an auxiliary device used in garbage treatment plants to process the smoke generated when incinerating non-recyclable garbage and improve environmental protection. It has been widely used in the fields of garbage treatment and environmental protection. The existing dedusting device used for garbage incineration comprises a dedusting tower, a water tank and a spray pump, the inside of the dedusting tower is provided with a working chamber, the top of the working chamber is provided with a spraying pipe, and the bottom of the spraying pipe is connected with multiple The left end of the dust removal tower is provided with an air inlet pipe, and an induced draft fan is arranged at the air inlet pipe. The top of the dust removal tower is provided with an air outlet pipe, and an axial flow fan is arranged at the outlet pipe. The input end of the pump communicates with the water tank, and the output end of the spray pump extends from the right end of the dust removal tower into the working chamber and communicates with the spray pipe; when the existing dust removal device for garbage incineration is used, the incineration The smoke and dust generated are introduced into the working chamber from the air inlet pipe, and the water in the water tank is pumped into the spray pipe by the spray pump and sprayed out from the output end of the sprinkler head, and the smoke and dust are reversely sprayed to remove impurities in the smoke and dust , the treated gas is discharged from the air outlet pipe under the action of the axial flow fan; in the use of the existing dust removal device for waste incineration, it is found that the effective coverage rate of the water mist on the smoke and dust is low, and the dust removal is not sufficient, resulting in practicality. Low; and the flow rate of smoke and dust is unstable, some smoke and water mist are easy to blow out from the air outlet pipe under the action of air flow, causing pollution to the atmospheric environment and low environmental protection; at the same time, its water consumption is large, resulting in waste of water resources , and produce a large amount of sewage, resulting in low reliability
