Description
Technical field
The utility model relates to a kind of spray gun using for desulphurization denitration operation.
Background technology
Desulphurization denitration tower is mainly by gas fume conveying system, absorption tower, spray system, the slurries circulatory system, slurries recovery system composition.
Industrial waste gas is transported to absorption tower by gas fume conveying system by the waste gas that has a large amount of sulfur dioxide, carbon dioxide etc., desulfurizing agents a large amount of in absorption tower are transported to tower body by spray system, fully contact with industrial waste gas with the desulfurizing agent of the ability of disengaging with certain pressure, produce chemical reaction, for at the bottom of making sulfur dioxide in waste gas generate sediment to flow to tower, be discharged to tower outer circulation by the slurries circulatory system and utilize, the industrial gasses after desulfurizing and purifying are discharged in air through desulfurizing tower chimney again.
At present, in the technique such as desulphurization denitration, flue gas conditioning, in spray system, be all generally to adopt spray gun, realize and spraying a fluid in definite scope region, to reach desirable mixed effect, improve efficiency and the quality of desulphurization denitration; But Shortcomings on existing spray gun structure, cannot solve short problem in service life, because spray gun is for a long time in the working environment in high temperature, cause the high and easily corrosion of spray gun surface temperature, in addition, spray gun swept area is little, need a large amount of desulfurizing agent output, cost has just improved greatly like this, is unfavorable for long-term development of enterprise, so the problems referred to above have been technical difficult problems for many years, be badly in need of solving.
Summary of the invention
The purpose of this utility model is to provide a kind of spray gun of modified desulphurization denitration, improves desulphurization denitration operating efficiency, increases the service life simultaneously.
The spray gun of modified desulphurization denitration, is characterized in that: comprise spray gun inner tube, one end welding point of described spray gun inner tube, other end welding gun rifle head; The outer wall of described spray gun inner tube forms threaded area, is provided with stop ring in a side of threaded area, also comprises the spray gun sleeve pipe being threaded with threaded area, on described spray gun sleeve pipe, is provided with inlet tube, on described inlet tube, is provided with cooling tube; Between one end of described spray gun sleeve pipe and described stop ring, be provided with end socket, the other end is provided with and is trumpet-shaped enlarging; On the inwall of described spray gun sleeve pipe, be provided with the 2-3 bar conducting element that uniformly-spaced spiral arranges.
Further preferably, described spray gun rifle head comprises stiff end, is provided with nozzle in the port of described stiff end by bearing, forms multiple spray orifices on described nozzle, and the cross section of described spray orifice is oval.
Further preferably, described spray orifice circular array is at nozzle-end.
Further preferably, described conducting element is the setting of inclination 30-45 degree spiral.
Further preferably, the height of described conducting element is at 3-5mm.
Further preferably, the cross section of described inlet tube is conical.
The utility model compared with prior art, the utlity model has following beneficial effect:
1, the utility model is in order to solve cooling problem; in actual use; adapter on spray gun sleeve pipe connects cooling water, and the setting of cooling tube can reduce the temperature of cooling water, that is to say; before cooling water is come in; the processing that just cools, enters in spray gun sleeve pipe temperature low like this, carries out temperature convection transmission with outside high temperature; can play the effect of protection spray gun, increase the service life.
2, in order to improve the mixing of material, improve desulphurization denitration operating efficiency, in the utility model, on the inwall of spray gun sleeve pipe, form and be provided with the 2-3 bar conducting element that uniformly-spaced spiral arranges, like this cooling water is rotated to output, not only can improves and the contact-making surface of described spray gun internal surface of sleeve pipe, the middle air column that forms, and in the time of output, nozzle is rotated to impact, nozzle is rotated, and from nozzle, urea out effectively contacts with cooling water like this, mixes.Nozzle is rotated injection like this, and radiating surface expands greatly, large with dusty gas contact-making surface, and the output quantity of urea and cooling water reduces, and cost is minimized.
3, the utility model, in order to improve jeting effect, is strengthened effect and the efficiency of desulphurization denitration, the spray gun rifle head in the utility model, comprise stiff end, port at described stiff end is provided with nozzle by bearing, forms multiple spray orifices on described nozzle, and the cross section of described spray orifice is oval; In this structure, the material spraying in nozzle penetrates from spray orifice, because the cross section of spray orifice is oval, forms so certain oblique shear force, and nozzle will form rotation, and spray on rotation limit, limit, and whole spray regime expands greatly, is beneficial to the operation of follow-up desulphurization denitration.
As from the foregoing, the utility model improves desulphurization denitration operating efficiency, increases the service life simultaneously.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
