Technical field the present invention relates to a kind of smoke dust-removing equipment, particularly relates to a kind of mist purification tower.
Background technology is when smelting iron and steel, station boiler, cement furnace, waste incineration etc. are produced; a large amount of flue gases can be produced; because the dustiness of these flue gases is high, viscosity large, the particularity of high humidity; sack cleaner, the electrostatic precipitator of employing routine are difficult to meet emission request; also emission request is can not meet with spray desulfurization with the water dedusting of routine; therefore, the smoke dust-removing equipment of employing in conjunction with the feature of flue gas, must guarantee environmental requirement stable emissions.
Summary of the invention the object of the present invention is to provide a kind of mist purification tower, this mist purification tower body amass little, efficiency is high, operating cost is low, wear-resistant, corrosion-resistant, high temperature resistant, performance is much better than electrostatic and bag-type dust.
Concrete technical scheme of the present invention is as follows:
The present invention mainly includes tower body, inlet channel, header tank and nozzle, and the tower body top of circular in cross-section has gas approach; The bottom of tower body establishes the outlet pipe and outlet conduit that communicate with its inside respectively; The inside of described tower body is provided with along several uniform contour header tanks of its inner peripheral surface, and each header tank is welded by metallic plate and the rectangular housing in longitudinal cross-section, and the bottom metal of header tank all establishes several osculums; Above-mentioned each header tank all communicates with the water inlet pipe A one end on tower body, and the other end of water inlet pipe A stretches out the outside of tower body; The inside of described tower body and the below being positioned at header tank is provided with along several uniform contour nozzle A of tower body inner peripheral surface, the axis of each nozzle A is all vertically intersected on the axis of tower body, each nozzle A is all fixed by the water inlet pipe B on tower body, one end of water inlet pipe B connects with the water inlet end of nozzle A, and the other end stretches out tower body outside; The inside of described tower body and the below being positioned at nozzle A is provided with along several uniform contour nozzle B of tower body inner peripheral surface, the axis of each nozzle B is all towards the inner peripheral surface of tower body, the water side of these nozzle B is between every two not relative on same circle, described each nozzle B is all fixed by the water inlet pipe C on tower body, one end of water inlet pipe C connects with the water inlet end of nozzle B, and the other end stretches out tower body outside;
Preferably, the inside of described tower body and the below being positioned at nozzle B are provided with two oblique rectangle deflection plates, and the upper end of each deflection plate all connects with the inwall of tower body, and these two deflection plates are oppositely arranged, and have free air space between the lower end of two deflection plates.
The present invention operationally, dustiness is high, viscosity is large, the flue gas of high humidity enters tower body inside by the top inlet of tower body, inlet channel A, B, C all connects water, current pass through collecting box, impact type moisture film is formed on tower body top, gas-water contact area reaches 100% substantially, nozzle A can make to form high thick fog closed water smoke in the middle part of tower body, gas-water contact area is made substantially to reach 200%, nozzle B can make to form the open water waterfall of waterfall formula bottom tower body, gas-water contact area is made substantially to reach 100%, like this, air-water contact through three layers: moisture film, atomization, water waterfall and flue gas be fully collisional mixing air-water contact washing in the same way, thus reach the effect of flue gas ash removal, purify air and to be discharged by outlet pipe, water is discharged by outlet conduit, establish deflection plate that current can be made to discharge bottom tower body more rapid, strengthen the circulation of water.
The present invention can carry out knockdown design according to the size of flue gas flow, and to meet the emission request of any flue gas flow, desulfurization dust-removing efficiency reaches more than 90%.Compared with prior art, volume of the present invention is little, efficiency is high, operating cost is low, wear-resistant, corrosion-resistant, high temperature resistant, and performance is much better than electrostatic and dust settling pocket technique.Be applicable to: smelting iron and steel, station boiler, cement furnace, waste incineration etc. industry dust-removal and desulfurizing demand.Gas, water engaging surface are long-pending up to 400%, and volume reduces more than 60%, and operating cost reduces by more than 50%.Dust removing effects and efficiency aspect are all better than electrostatic precipitator and sack cleaner, and have and remove PM2.5 function; Social benefit, economic benefit are all very considerable.
