The device has the characteristics of wide application range, good cooling effect, high purification efficiency, simple structure and easy manufacture.
Description
Technical field
A kind of shower nozzle relates to a kind of shower nozzle that is used for the spray liquid that flue gas cool-down, purification of metallurgy chemical process.
Background technology
In smelting process, flue gas during smelting discharges or relieving haperacidity after will carrying out purified treatment usually again.In sulfur-bearing metallurgical off-gas acid-making process, when flue gas during smelting purifies, usually flue gas is contacted with spray liquid, purify, spray liquid utilizes the shower nozzle ejection to produce.
At present, the shower nozzle in usefulness has centrifugal sprinkler, porous nozzle etc.Centrifugal sprinkler is usually used in void tower equipment, and this shower nozzle applicability is strong, air resistance is little, but because the complete equipment volume is big, efficient is low, investment is many.
Porous nozzle is usually used in packed tower, foaming tower etc., and this shower nozzle atomizing effect is good, sprinkle density is even.But because the shower nozzle difficulty of processing is big, need higher relatively atomizing pressure, strict to the circulation fluid concentration requirement, need a large amount of moisturizings.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned prior art, provides a kind of ability will lower the temperature and the disposable completion of purification process, and is applicable to the shower nozzle of the circulation fluid concentration range of broad.
The purpose of the utility model realizes through following technical scheme.
A kind of shower nozzle is characterized in that its structure comprises:
Shower nozzle core body-this core body is one by being the hydrojet fluid pipeline section of straight tube for the spray liquid feed liquor pipeline section of straight tube, the undergauge pipeline section that combines as a whole with undergauge pipeline section upper end combines as a whole; On feed liquor pipeline section sidewall, be uniformly distributed with and have branch dosing hole;
Nozzle boss--this nozzle boss backs down on being with shower nozzle core body feed tube section upper end outer wall thread and cooperates connection and spacer sleeve to be contained in the straight tube calyptra of the feed liquor pipeline section of shower nozzle core body;
Inner thread affixed circular discs in bottom under the straight tube calyptra straight tube that separatory dish-this separatory dish is an outer and nozzle boss; This circular discs has the center fluid hole between two parties, and limit portion circumferentially is uniformly distributed with and has the limit fluid hole, and the position, annular gap that forms between separatory web fluid hole and shower nozzle core body and nozzle boss is corresponding; Separatory dish upper disk surface roof pressure is in shower nozzle core body lower end.
A kind of shower nozzle of the utility model, it is characterized in that being uniformly distributed with on the said shower nozzle core body feed tube section sidewall branch dosing hole that has is that 3 120 degree five equilibriums are hole arranged.
A kind of shower nozzle of the utility model is characterized in that outer wall is connected with external flange in the nozzle boss lower end.
A kind of shower nozzle of the utility model is used for adiabatic evaporation cleaning system and tail gas desulphurization system, will lower the temperature and the disposable efficient completion of purification work, and be applicable to the circulation fluid concentration range of broad.Have applied widely, good cooling effect, characteristics that purification efficiency is high, and simple in structure, be easy to make.

The specific embodiment
A kind of shower nozzle, its structure comprises: shower nozzle core body 1-this core body is one by being the hydrojet fluid pipeline section of straight tube for the spray liquid feed liquor pipeline section of straight tube, the undergauge pipeline section that combines as a whole with undergauge pipeline section upper end combines as a whole; On feed liquor pipeline section sidewall, be uniformly distributed with and have branch dosing hole 2; This nozzle boss of nozzle boss 3--backs down on being with shower nozzle core body feed tube section upper end outer wall thread and cooperates connection and spacer sleeve to be contained in the straight tube calyptra of the feed liquor pipeline section of shower nozzle core body; Inner thread affixed circular discs in bottom under the straight tube calyptra straight tube that separatory dish 4-this separatory dish is an outer and nozzle boss; This circular discs has center fluid hole 5 between two parties, and limit portion circumferentially is uniformly distributed with and has limit fluid hole 6, and the position, annular gap that forms between separatory web fluid hole and shower nozzle core body and nozzle boss is corresponding; Separatory dish upper disk surface roof pressure is in shower nozzle core body lower end.
During use,, be connected with external flange 7 through nozzle boss lower end outer wall and link with external feeding device with a kind of shower nozzle of the utility model.Liquid is shunted through the separatory dish earlier after feed tube gets into, and 70% left and right sides liquid is that the main channel gets into sprayer body with the center fluid hole of separatory dish; All the other liquid get into nozzle boss and the external wall of sprinkler core forms the annular gap; Annulus between nozzle boss and shower nozzle core body, the whirl hole of arranging through 3 120 branches such as degree of shower nozzle core body bottom again, this whirl hole can have certain inclination angle adding man-hour; Get into sprayer body; Cause the liquid in the sprayer body to produce rotation, fluid pressure is more evenly distributed, and reduce the sprayer body internal resistance.
Embodiment
The purification section of metallurgical off-gas acid-making enterprise, according to corresponding technology cooling dedusting requirement, intake air temperature is between 200-400 ℃, and air outlet temperature is between 50-60 ℃, and gas flow rate should be controlled between the 10-15m/s, and flow rate of liquid is controlled between the 10-20m/s; Decontaminating liquid forms the fluid that one rotates up through the shower nozzle effect, is covered with whole exhaust gases passes; Contact with flue gas is reverse, on contact-making surface, because the interaction of the two; Form the froth bed of certain altitude, dust in flue gas is captured bigger gas-liquid contact area; Guaranteed the abundant absorption of liquid, and gas-liquid heat exchange is abundant, has strengthened the flue gas cooling effect to some soluble gas in the flue gas; After this device came into operation, the flue-gas temperature that can guarantee to get into subsequent processing was below 60 ℃, and efficiency of dust collection reaches more than 98%, and solid content is lower than 30% liquid and can normally uses.
