Abstract
The invention discloses a dedusting device for exhaust gas. The dedusting device comprises a dedusting box which is fixed on a frame. An exhaust gas inlet is reserved on one side of the dedusting box; and an ash collecting hopper is reserved at the bottom of the dedusting box. A flying dust trapping device is reserved at a position close to the exhaust gas inlet in the dedusting box. The flying dust trapping device comprises a wind screen, waste gas absorption trough and a spark trapping grid. The wind screen is vertically arranged in the dedusting box; the center of the waste gas absorption trough is connected with the bottom of the wind screen; the spark trapping grid is arranged on one side of the wind screen close to the exhaust gas inlet; a spraying device is arranged on the other side of the wind screen in the dedusting box; and the spraying device is connected with a water pipe. A wastewater purification pool is arranged at the bottom of the ash collecting hopper; and the bottom of the wastewater purification pool is connected with the water pipe through a return pipeline. With the flying dust trapping device arranged at the position close to the exhaust gas inlet in the dedusting box, flying dust can be trapped effectively; residual acid gas in the exhaust gas can be effectively absorbed by reagent in the waste gas absorption trough; and water after treated in the wastewater purification pool can be recycled by the spraying device.
Description
Technical field
The present invention relates to a kind of dust arrester, relate in particular to a kind of fume dust remover.
Background technology
General blast furnace gas dry dusting adopts bag-type dust collector, and filter bag is fixed on the dust-removing box mostly, and filter bag is easy to damage under conditions such as high temperature, high strength, the maintenance of filter bag, change very inconvenient; In addition, also adopt the filter cylinder dedusting, dust removing effects is not obvious, residual acid gas easy-clear not in the flue gas.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide a kind of efficiency of dust collection height, the fume dust remover that expense is low.
