The specific embodiment

As shown in Figure 1 and Figure 2, smoke-eliminating refrigeratory dust collector of the present utility model comprises the flue gas distributor 2 that links to each other with flue 1, sidewall at flue gas distributor 2 offers multiple tracks flue gas air outlet, and this each flue gas air outlet links to each other with the housing 4 of each air blast respectively by air inlet pipe 3.General air blast is provided with the 3-4 road and is advisable, and see that the discharge capacity of flue gas suitably increases and decreases.The front end of each air blast fan blade 6 and the motor output shaft of high-speed rotary motor 5 ends are fixed.The rotating shaft front axle sidewall through hole of the output shaft 5 of high-speed rotary motor, the one end docks with water inlet pipe by mechanical sealing member 19, its terminal mouth of pipe sealing.The other end of the output shaft 5 of high-speed rotary motor stretches in the air inlet pipe 3, the alternate multiple tracks screen frame 11 that is fixed with of its dip section, and as shown in Figure 3, the screen frame among the figure is 3 roads, also four roads, five roads or multiple tracks can be set according to circumstances.The screen frame perisporium is to the alternate rotating vane 7 that is fixed with between the sleeve at center, composite steel silk screen 8 in alternate stretch-draw between the axial perisporium of screen frame 11, and output shaft between composite steel silk screen 8 and the output shaft perisporium in air blast all are evenly equipped with intensive water spray aperture 9.Sidewall at air blast has wind pipe 10, and this wind pipe upwards enters gather qi together tube 14 after the bending downwards, and gather qi together tube 14 upper ends have blast pipe 21, and its bottom has condensed water to enter the water circulating water chennel by pipeline, can use continuously.Water is delivered to water dispenser 12 backs do the water inlet use for multiple tracks high-speed rotary motor, water inlet pipe.Having the ostium excurrens 15 that leads to outfall sewer 13 near wind pipe 10 downward bending places, the condensate water of flue gas after atomizing, air blast fan blade stir is after outfall sewer 13 feeds the water circulating water chennel, for recycling.

As shown in Figure 4, if run into more relatively large flue gas, for example: discharged flue gas such as power plant, smeltery and Foundry Works, be preferably near wind pipe 10 downward bending places and have the water inlet pipe 16 that leads to inwall, and stretch in the wind pipe, the output shaft 17 that is driven by common electric machine axially stretches among the air-out house steward 10, at alternate above-mentioned described screen frame and the many group composite steel silk screens of being provided with of dip section, have intensive a plurality of water spray aperture 18 stretching into wind pipe on the sidewall between many groups composite steel silk screen, effect is better after three atomizings are handled like this.

During use, open water pump 22, open each high-speed rotary motor simultaneously, water dispenser 12 supplies water to the output shaft that each high-speed rotary motor drives simultaneously, motor output shaft rotates at a high speed, from the water of output shaft aperture ejection because centrifugal action, with the powerful collision of the blade on the rotating vane, be ground into a large amount of vaporific smog, collide and stir with the flue gas that heads on into, contact, exchange, they can fully be dissolved in the water, further enter again in the air blast, further exchange with the water smoke of the aperture of air blast fan blade and rotating output shaft ejection, stir, after a large amount of flue gases and hot gas are further dissolved, little gas enters gather qi together tube 14 through wind pipe 10, and high-temperature flue gas is after above-mentioned processing, and heat significantly reduces.Water enters outfall sewer 13 from bending place, wind pipe 10 bottom through ostium excurrens 15, enters behind the circulating water chennel recirculation and uses.Axially having water-intake small pipe again near the downward bending place of wind pipe, output shaft by driven by motor axially stretches in the air-out house steward 10, handle through atomizings for the third time such as water spray and aperture 18 water sprays, the heat and the waste gas of being discharged by blast pipe 21 have reached discharging standards fully.
