Description
Technical field
The utility model relates to a kind of shower nozzle, specifically refers to a kind of chilling shower nozzle that cooling high-temperature fume is processed that is applicable to.
Background technology
Recent domestic environmental requirement is more and more higher, various furnace flue gas, petrochemical industry tail gas must be after dust-removal and desulfurizing qualified discharge.By retrieval, China Patent Publication No. is: CN1488424A discloses a kind of Turbulent_washing gas treating apparatus, its structure includes the parts such as scrubbing tower, collecting tank and washing nozzle, scrubbing tower is tubular pyramidal structure, the dynamic equilibrium exchange field of establishing flue gas and cleaning solution by washing nozzle in it, scrubbing tower is connected with collecting tank by bellows, forms an integral body.At scrubbing tower top, downflow weir is set, the overflow of downflow weir cleaning solution forms falling liquid film, and below scrubbing tower backing layer is played to liquid film protective effect.This technology has realized the desulfurization and dedusting effect of very good gas purification.
But in use still there is following problem in this equipment: the temperature of furnace flue gas, petrochemical industry tail gas is often very high; rapids rushes the scrubbing tower backing layer of cleaning solution (dynamic equilibrium exchange field) top often because downflow weir overflow liquid film protection inefficacy high temperature damages, and causes service life of equipment greatly to reduce.
In addition; although be also used for spray cooling with various shower nozzles in prior art; form is also different; but the form of the liquid of its ejection is horn-like mostly, focus on atomization; a little less than impulsive force; at rapids, rinse and to wash in the scrubbing tower with certain gas speed, be difficult to form the torrent water curtain that taper is flat, in shorter flue, cannot realize cooling and rush fully fast the scrubbing tower backing layer surface formation liquid film protective layer of cleaning solution (dynamic equilibrium exchange field) top at rapids rapidly to high-temperature flue gas.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provide a kind of, can carry out high-temperature flue gas coolingly rapidly, effectively prevents the chilling shower nozzle that high-temperature flue gas damages the high temperature of scrubbing tower inducer.
For achieving the above object, the technical solution of the utility model is: described chilling shower nozzle includes annular nozzle seat and feed tube, in described annular nozzle seat, be provided with the inlet being connected with feed tube, on the inwall of this annular nozzle seat, circumferentially offer helicla flute, the relative spiral fluted bilateral symmetry of this annular nozzle seat is provided with the liquid stream of circular cone shape and disperses guide face, this spiral fluted degree of depth extends spirally direction along it and successively decreases gradually, and spiral fluted initiating terminal is connected with inlet, the relative spiral fluted tail end of inwall of described annular nozzle seat is provided with for liquid is dispersed to a pair of wall of tiltedly leading that guide face carries out water conservancy diversion toward two liquid streams of annular nozzle seat both sides.
By this setting, liquid enters annular nozzle seat from this feed tube, then liquid is circumferentially guided by helicla flute, and finally by tiltedly leading wall shunting and dispersing guide face from the liquid stream of both sides, become the conical surface to be shot out dispersing, by this chilling shower nozzle, the liquid in feed tube can be become to the torrent water curtain of flat cone curtain shape, and the liquid in torrent water curtain itself also has helical angle speed, it is very even that this helical angle speed impels liquid dispersion to obtain, greatly increased the specific area of liquid, the torrent water curtain that high-temperature flue gas produces by this chilling shower nozzle, to make high-temperature flue gas rapidly with torrent water curtain in drop carry out fierceness and collide, fully contact and fast cooling, cooling-down effect is ideal, the torrent water curtain of simultaneously flat cone curtain shape can be resisted the flue gas stream of certain gas speed in scrubbing tower, directive tower wall, at rapids, rush fully fast the scrubbing tower backing layer surface formation liquid film protective layer of cleaning solution (dynamic equilibrium exchange field) top, thereby effectively prevent that high-temperature flue gas from damaging the high temperature of scrubbing tower inducer, service life and the stability of scrubbing tower have greatly been improved.
Further arranging is that described spiral fluted tail end projection is provided with triangle flange, and the described a pair of wall of tiltedly leading is arranged on two isometrical limits of this triangle flange.
Further arranging is the top that the back side gear of described triangle flange is located at the inlet of annular nozzle seat.By this setting, make triangle flange in upward direction, carry out regulation to the direction of the liquid spraying in inlet, liquid is guided away from helicla flute, and then make liquid in helicla flute, obtain larger helical angle speed, and then make liquid can be dispersed into more tiny drop, improve the contact gear ratio surface area of liquid, and then improved the cooling-down effect to high-temperature flue gas.
Further arranging is that the feed tube top of described chilling shower nozzle is provided with side protuberance, is provided with for being communicated with the oblique flow-guiding channel of the inlet of feed pathway in feed tube and annular nozzle seat in this side protuberance.By this setting, can carry out preliminary tiltedly water conservancy diversion to flowing to the water of inlet in the feed pathway in feed tube, make the kinergety of liquid own can convert more helical angle speed to, further improved the contact gear ratio surface area of liquid.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
