Smoke dust purification machine adopting water-bath needle rotating method

Abstract

The invention discloses a smoke dust purification machine adopting a water-bath needle rotating method. The smoke dust purification machine comprises a bracket, wherein a liquid storage tank body is arranged at the bottom of the bracket; a blow-off pipe is connected to the bottom of the liquid storage tank body; a plurality of vent hole plates are arranged in parallel on the liquid storage tank body; a purification cavity is formed above each vent hole plate; an annular dust collection groove is connected to the top of each purification cavity; a dust liquid discharge hole is formed in the bottom surface of the annular dust collection groove; a dust discharge liquid seal pipe is connected to the dust liquid discharge hole; the lower end of the dust discharge liquid seal pipe is inserted in the liquid storage tank body; a needle rotating wheel is mounted in the annular dust collection groove and fixedly mounted at the end part of an output shaft of a motor in a sleeving manner. Dusty gas penetrates through small holes of the vent hole plates from bottom to top at a certain flow speed and passes through a liquid region, a bubbling region and a splash region in sequence; ascending splash is intercepted, cut and collided by a plurality of needles arranged in a radial shape and rotating at a high speed, so that accumulated dust of droplets is adsorbed; the needle rotating wheel forms a vortex field with a unified angular speed in a rotary process, so that a separation effect is further enhanced; the accumulated dust of droplets is very easily thrown into the annular dust collection groove along the needles under the action of centrifugal force and separated in time; the purified gas is discharged from the upper end of the needle rotating wheel.

Description

technical field [0001] The invention relates to a smoke dust purification treatment device, in particular to a water bath needle turning smoke dust purification machine. Background technique [0002] Coal-fired thermal power boilers and industrial furnaces, although the exhausted flue gas has been dedusted by bag type or electrostatic dry dust collectors, it still has a dust content of tens of milligrams per cubic meter, and the total amount is huge. The gypsum rain, water mist and escaped SO3 produced by wet desulfurization are discharged into the atmosphere, which has a great impact on the generation of smog and threatens human health, so further purification treatment is required. Traditional dry dust collectors cannot solve the above problems. Although wet dust collectors can remove dust particles above 0.1um and have relatively high purification efficiency, traditional wet dust collectors mainly include wet electrostatic precipitators and scrubber dust collectors.
