Flue gas dust removal equipment for atmospheric pollution control

Abstract

The invention relates to the technical field of flue gas dust removal, especially to flue gas dust removal equipment for atmospheric pollution prevention and control. The flue gas dust removal equipment comprises a treatment box, wherein one end of a first reciprocating screw is connected with a third rotating shaft; a fourth bevel gear is connected to the end, located on the outer side of the treatment box, of the third rotating shaft; a first moving block is connected to the first reciprocating screw; a first limiting frame is arranged in and connected with the treatment box; a scraping plate is connected to the upper end of the supporting rod; a filler is arranged in and fixedly connected with the treatment box; the bottom end of the filler makes contact with the upper end of the scraping plate; and through holes are formed in the two sides of the treatment box. According to the invention, an external controller controls a power mechanism to start and then drives the second rotatingshaft to rotate; the first moving block reciprocates in a horizontal direction under limiting of a first limiting frame; the first moving block drives the scraping plate to reciprocate in the horizontal direction through the supporting rod; the reciprocating scraping plate scrapes foam bonded to the lower surface of the filler, so an air inlet gap in the bottom of the filler is not blocked, and asmoke discharging speed is increased.

Description

technical field [0001] The invention relates to the technical field of flue gas dedusting, in particular to a flue gas dedusting device for air pollution prevention and control. Background technique [0002] With the rapid development of industry, the high-temperature flue gas generated in the industrial production process needs to be dedusted before it can be discharged into the atmosphere. When the high-temperature flue gas generated in the industrial production process is treated, the high-temperature flue gas is first discharged into the heat exchanger Perform heat exchange, use the waste heat of high-temperature flue gas to add water to recycle the heat of high-temperature flue gas, and finally pass the heat-exchanged flue gas into the dust collection equipment for dust removal, and discharge it into the atmosphere after dust removal treatment. [0003] When the flue gas after heat exchange is processed, the method of foam spraying is usually used for dust removal. The ...

Problems solved by technology

[0003] When the flue gas after heat exchange is processed, the method of foam spraying is usually used for dust removal. The liquid is sprayed onto the dispersion plate. When the gas passes through the dispersion plate, foam is generated between the liquid on the dispersion plate and the gas passes through the foam. , so as to remove the dust in the gas. Due to the continuous introduction of the gas, the gas has a certain flow velocity, and it will rise with the foam during the rising process. Finally, the dust-stained foam will be separated from the gas through the filler and the gas will be separated. Release, because the foam has a certain viscosity, the separated foam sticks to the bottom of the filler, and with the progress of dust removal, the foam at the bottom of the filler gradually increases, covering the air intake gap at the bottom of the filler, so that the smoke cannot pass through quickly Packing, which reduces the speed of flue gas emission
