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
The present invention relates to a kind of purification treatment device for smoke dust, be specifically related to a kind of water-bath rotating the needle method dust purifier.
Background technology
Coal-fired Thermal Power boiler and industrial furnace cellar for storing things, the flue gas of discharging, although have passed through the dedusting of the dry collector such as pocket type or electrostatic, but still have the dustiness of tens milligrams/cubic metre, total amount is huge, the gypsum rain especially also having wet desulphurization to produce, the SO3 etc. of water smoke and escape, be discharged in air, the generation of haze is had a significant impact, threatens the healthy of people, therefore need to do further purified treatment.Traditional dry collector cannot overcome the above problems, although wet scrubber can except the grit of lower more than 0.1um, purification efficiency is relatively high, but traditional wet scrubber mainly contains wet cottrell and Washing dust remover, and wet cottrell has started application in indivedual apparatus of thermo-electric power boiler gas cleaning, but, complex structure, involve great expense, operation and maintenance cost is high, conventional washing formula deduster, its vapor-liquid separating structure is passive type substantially, some water smoke is separated not get off, and resistance is large, consume energy high, according to rotary filter net disk structure, during the sticking gypsum rain of separating belt, meeting control of dust in its wheel rim frame, or be adsorbed on filter screen silk, not easy to clean, and separating effect can be made to be deteriorated.
Summary of the invention
The object of the invention is for the technical problem such as cleaner complex structure, dust removing effects in prior art be not good, a kind of water-bath rotating the needle method dust purifier is provided, this clearing machine structure is simple, manufacturing cost is low, energy consumption is low, water saving, high to purification efficiencies such as dust particale, water smoke, gypsum mist and SO3, working service is convenient, long working life.
Technical scheme: a kind of water-bath rotating the needle method dust purifier, comprise support, liquid holding groove body is placed with in frame bottom, at cradle top, brace summer is installed, brace summer is placed with lamina tecti, lamina tecti is vertically provided with motor, blow-off pipe is connected with bottom described liquid holding groove body, liquid holding groove body is placed with some ventilative orifice plates side by side, liquid is loaded with in described liquid holding groove body, liquid covers ventilative orifice plate, form fluid zone, one purification chamber is all installed above each ventilative orifice plate, control of dust cannelure is connected with at purification top of chamber, described control of dust cannelure bottom surface has dirt liquid floss hole, dust discharge liquid sealing pipe is connected with at described dirt liquid floss hole place, described dust discharge liquid sealing pipe lower end is inserted in liquid holding groove body groove, rotating the needle wheel is installed in described control of dust cannelure, described rotating the needle wheel by least one deck radially, the dials of the even isometric layout of spininess is fixedly formed by fixed cover after vertically being suppressed by welding or adhesive, fixed cover is fixedly set in motor output shaft end.
Based on technique scheme, described ventilative orifice plate is provided with liquid supplementation pipe, in liquid holding groove body groove, is placed with fluid level measuring instrument, described liquid supplementation pipe is provided with magnetic valve, magnetic valve is connected with liquid level controller by wire, and described liquid level controller is connected with fluid level measuring instrument through wire.
Based on technique scheme, described control of dust cannelure cross section is in " C " font, and take turns position relative with rotating the needle, and described control of dust cannelure lower port diameter is less than rotating the needle and takes turns external diameter, back cut diameter is greater than rotating the needle wheel external diameter, and control of dust cannelure groove inner height is greater than rotating the needle wheel vertical height.
Based on technique scheme, described liquid holding groove body is designed to " well " font groove, and groove bottom is inclined-plane, and blow-off pipe is positioned at inclined-plane lowest part.
Based on technique scheme, described purification chamber is up-narrow and down-wide trapezoidal container.
Based on technique scheme, the angle of described rotating the needle wheel between the adjacent needles of same layer dials is 2-3 °.
