Technical field
The present invention relates to a kind of novel spray gun for using in desulphurization denitration operation.
Background technology
Desulphurization denitration tower is mainly by gas fume conveying system, absorption tower, and sprinkling system, the slurries recycle system, slurries recovery system form.
The waste gas having a large amount of sulfurous gas, carbonic acid gas etc. is transported to absorption tower by gas fume conveying system by industrial gaseous waste, sweetening agents a large amount of in absorption tower is transported to tower body by sprinkling system, fully contact with industrial gaseous waste with the sweetening agent of certain pressure with the ability of disengaging, produce chemical reaction, generating throw out to make the sulfurous gas in waste gas flows at the bottom of tower, being discharged to tower outer circulation by the slurries recycle system to utilize, the industrial gasses after desulfurizing and purifying are discharged in air through thionizer chimney again.
At present, in the technique such as desulphurization denitration, flue gas conditioning, in sprinkling system, it is all generally adopt spray gun, it is achieved spray a fluid in the scope region determined, to reach desirable mixed effect, it is to increase the efficiency of desulphurization denitration and quality; But Shortcomings on existing spray gun structure, one carrys out complex structure, and pipe fitting is many, pipe middle sleeve, installs trouble, very loaded down with trivial details; Two cannot solve short problem in work-ing life, owing to spray gun is in the Working environment of high temperature for a long time, cause spray gun surface temperature height and easily corrode, so the problems referred to above have been the difficult problems in technology for many years, are badly in need of solving.
Summary of the invention
It is an object of the invention to provide a kind of novel spray gun for desulphurization denitration, easy for installation, it is to increase desulphurization denitration operation efficiency, extends work-ing life simultaneously.
For the novel spray gun of desulphurization denitration, it is characterised in that: comprise pipe in spray gun, one end welding joint of pipe in described spray gun, the other end welding spray gun rifle head; In described spray gun, the outer wall of pipe is provided with bayonet socket and rapid-acting coupling, it is provided with little metal o-ring between bayonet socket and described spray gun inner pipe wall, it is provided with big metal o-ring between described rapid-acting coupling and described spray gun inner pipe wall, described rapid-acting coupling also connects a spray gun sleeve pipe, described spray gun sleeve pipe is provided with inlet pipe, described inlet pipe is provided with cooling tube; The outer wall of described spray gun sleeve pipe is provided with flange, and port is provided with in circular platform type shower nozzle enlarging; It is provided with position of splitter between the inwall and described spray gun rifle head of described spray gun sleeve pipe.
Further preferably, described spray gun rifle head comprises inboardend, is provided with nozzle in the port of described inboardend, forms multiple spray orifice on described nozzle, and the aperture of described spray orifice is at 0.5-2mm.
Further preferably, described spray orifice circular array is at nozzle-end.
Further preferably, the outer wall of described inboardend fixes position of splitter.
Further preferably, described little metal o-ring is buckled on described big metal o-ring.
Compared with prior art, the present invention has following useful effect in the present invention:
1, the present invention is in order to solve cooling problem, in actual use, adapter on spray gun sleeve pipe connects pressurized air, and the setting of cooling tube can reduce the temperature of pressurized air, that is, before pressurized air is come in, just carry out cooling process, enter temperature in spray gun sleeve pipe so low, temperature convection transmission is carried out with the high temperature of outside, the effect of protection spray gun can be played, also can improve certain air pressure simultaneously, it is beneficial to and mixes with urea, pipe connects in spray gun urea, when urea from nozzle out, pressurized gas surrounds nozzle, form mixing, under the drive of gas, it is ejected into outside, carry out desulphurization denitration operation. it can thus be seen that the present invention not only protects whole spray gun, extend work-ing life, and improve the mixing of material, expand the scope of whole injection.
2, the present invention is in order to improve jeting effect, strengthens effect and the efficiency of desulphurization denitration, the spray gun rifle head in the present invention, it comprises inboardend, being provided with nozzle in the port of described inboardend, form multiple spray orifice on described nozzle, the aperture of described spray orifice is at 0.5-2mm; In this structure, the spray orifice on nozzle, whole spray regime expands, and is beneficial to external compression air and mixes, is beneficial to the operation of follow-up desulphurization denitration.
3, in the present invention, in order to succinctly easy for installation, in described spray gun, the outer wall of pipe is provided with bayonet socket and rapid-acting coupling, is provided with little metal o-ring between bayonet socket and described spray gun inner pipe wall, is provided with big metal o-ring between described rapid-acting coupling and described spray gun inner pipe wall, such setting, not only while playing sealing, and can well fixedly mount, it is to increase the installation of rapid-acting coupling, and the installation between spray gun sleeve pipe with pipe in spray gun is connected, operation is very easy.
As from the foregoing, the present invention is easy for installation, it is to increase desulphurization denitration operation efficiency, extends work-ing life simultaneously.
In order to explain the technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
