Flue gas traversing type high-pressure spraying dust remover

Abstract

The invention discloses a flue gas traversing type high-pressure spraying dust remover, which comprises a high-pressure spraying chamber, a water storage tank, a circulating water flowing tank, an inlet smoke passing chamber and an outlet smoke passing chamber, the high-pressure spraying chamber is of a funnel-shaped cavity structure composed of a porous side plate and a shell outer plate, an L-shaped water receiving plate is arranged on the inner side surface of the porous side plate, and smoke passing holes are formed in a vertical plate section; the multiple stages of L-shaped water receiving plates form a step structure, and a spraying pipe is arranged at the top of the high-pressure spraying chamber; activated carbon filler and a top plate water outlet are arranged at the bottom of the reservoir; the inlet smoke passing chamber is provided with a first porous partition plate, a smoke inlet pipe connector and a first baffle plate. The outlet smoke passing chamber is provided with asecond porous partition plate, a smoke outlet pipe connector and a second baffle plate. By means of the perforated plate smoke guide structure and reasonable structural design and space layout, smokeis sequentially subjected to the water-gas fusion process of high-pressure spraying, water curtain traversing and water mist, the fusion process is reasonable and orderly, the contact area and fusiondegree of water fluid and the smoke are increased, and the desulfurization and dust removal effects are improved.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal treatment, in particular to a flue gas crossing type high-pressure spray dust collector. Background technique [0002] The high-pressure spray desulfurization and dust removal for flue gas treatment in small-scale waste incineration treatment equipment has become an indispensable link, but most of them show that the treatment medium receives high-pressure spray in a mixed flow state to complete the whole process of desulfurization and dust removal. [0003] An existing supporting technical scheme is: set an upright cylinder, the top cover is set in a cut spherical shape, the outlet of the treatment medium is set in the middle, and the spray pipe insertion openings equipped with high-pressure nozzles are distributed around the outlet, which are sealed after insertion to prevent Air leakage; one side of the middle and lower part of the cylinder is provided with a treatment medium inlet...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the above-mentioned prior art is that the processing medium enters the high-pressure spray chamber from the inlet pipe joint on the lower side and flows upward toward the smoke outlet pipe joint set in the middle of the top cover, and it is basically in a state of beam fluid

In this way, the shape of the treatment medium in contact with the high-pressure spray water is limited, and it is difficult to form the boundary position of the medium mixed flow between the medium beam fluid and the treatment chamber, which in turn affects the fusion degree of the high-pressure spray water and the treatment medium, making it difficult to achieve the desired effect of desulfurization and dust removal. target
