Background technology
Desulphurization denitration tower is mainly by gas fume conveying system, absorption tower, and spray system, the slurries circulatory system, slurries recovery system form.
Industrial waste gas will have the waste gas of a large amount of sulfur dioxide, carbon dioxide etc. to be transported to absorption tower by gas fume conveying system, desulfurizing agents a large amount of in absorption tower are transported to tower body by spray system, with certain pressure, fully contact with industrial waste gas with the desulfurizing agent of the ability of disengaging, produce chemical reaction, for at the bottom of making sulfur dioxide in waste gas generate sediment to flow to tower, by the slurries circulatory system, be discharged to tower outer circulation and utilize, the industrial gasses after desulfurizing and purifying are discharged in air through desulfurizing tower chimney again.
At present, in the techniques such as desulphurization denitration, flue gas conditioning, need to spray a fluid into definite position with spray gun, reach desirable mixed effect; During use, spray gun is in high-temperature flue gas, and the time one is long, high-temperature flue gas will make spray gun and the fluid superheat in gun barrel, and fluid tends to vaporize in gun barrel, causes spray gun internal pressure to rise, due to the variation of gun barrel internal pressure, do not reach desirable mixed effect.
In addition, the rising of the strong overpressure that fluid gasification causes, can cause spray gun explosion when serious, and service life is short, affects equipment and operating personnel's safety; The problems referred to above have been technical difficult problems for many years, are badly in need of solving.
Summary of the invention
The object of the present invention is to provide a kind of modified spray gun, improve desulphurization denitration operating efficiency, increase the service life simultaneously, reduce enterprise's use cost.
Modified spray gun, it is characterized in that: comprise spray gun inner tube, one end welding point of described spray gun inner tube, other end welding direct current shower nozzle, in the outside of described spray gun inner tube, be provided with spray gun outer tube, on described spray gun outer tube, welding is taken over, one end of described spray gun outer tube is sealedly and fixedly connected by the outer wall of end socket and described spray gun inner tube, other end welding tip cover, the other end of described nozzle cage forms necking end, the port of export of described direct current shower nozzle is arranged in described necking end, the port welding tip sleeve pipe of described necking end, the end welding tip head of described nozzle casing.
Further preferably, described nozzle head comprises nozzle carrier, on described nozzle carrier, is provided with nozzle, and the end of described nozzle forms a plurality of spray orifices, and the diameter of described spray orifice is between 0.5-1mm.The setting of this structure, is conducive to improve and expand the dispersion face of desulfurizing agent, improves the area of desulphurization denitration.
