The purpose of the utility model Venturi tube moisture film cyclone dust collectors, be to overcome above-mentioned shortcoming and a kind of Venturi tube moisture film cyclone dust collectors of designing, take the tangential air intake of top Venturi tube, reduce the body volume of deduster, again, under the inner core effect, force flue gas to be rotated down, big dust particle and cohesion dust directly are collected, interior rotation pure qi (oxygen) is directly discharged alkali lye by inner core and is flowed down by the downflow weir outside, on moisture film cyclone dust removal wall, form and evenly continue dirty moisture film, good for fine dusts and big dust particle collecting effect, avoid flowing down and form moisture film by the inboard, the deduster water phenomenon, the Venturi tube spray, go into the water ripples of moisture film cyclone dust collectors, moisture film absorbs sulfur dioxide three step desulfurization, voltage-stablizer control stable level, overflow launder is provided with the sawtooth weir, in establish dividing plate and avoid water to form turbulent flow and the moving inhomogeneous and flue gas with water of moisture film that causes of string back and forth.
The utility model Venturi tube moisture film cyclone dust collectors take following technical scheme to realize, it is to be provided with water level control voltage-stablizer and supporting leg by moisture film cyclone dust collectors lower end, overflow launder is provided with that the inboard high outside, sawtooth weir is low to be connected by bolting with flange, flue gas tangentially enters from the top Venturi tube, inner core is that exhanst gas outlet is connected with flange, ring pipe is connected with flange, Venturi tube and moisture film cyclone dust collectors are connected in flange, nozzle is by being bolted to throat on the Venturi tube, the ring pipe arm inserts in the overflow launder, moisture film cyclone dust collectors bottom is provided with bullet, the top is provided with cylinder, rectangular box is to establish dividing plate in the water level control voltage-stablizer, two Room are communicated with by steel pipe, form a sealing liquid level, and the chamber connects a steel pipe that leads to moisture film cyclone dust collectors bullet on the rectangular box, be provided with a steel pipe on the top of rectangular box and be communicated with moisture film cyclone dust collectors cylindrical shell, outlet pipe is located at down the top side of chamber.
The effect of the utility model Venturi tube moisture film cyclone dust collectors is simple in structure, easy to operate, the efficiency of dust collection height, three step desulfurized effects are good, cost is low, adopts the control of water level control voltage-stablizer, avoids the deduster water-filling too much, cause the boiler irregular operating, the formation of the even moisture film of overflow launder absorbs the collection of sulfur dioxide gas and dust again.Be widely used in civilian and dust-removal and desulfurizing Industrial Boiler.
The utility model Venturi tube moisture film cyclone dust collectors will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the utility model Venturi tube moisture film cyclone dust collectors.
