Description
Technical field
The present invention relates to spray gun spray nozzle technical fields, more particularly to a kind of three Fluid sprayer spray head of exterior mixing.
Background technique
With the quickening of process of industrialization, environmental pollution is got worse, especially atmosphere polluting problem, is even more seriously endangered
The health of human body.The major pollutants of atmosphere pollution have pulp mill, paper mill, garbage burning factory etc. to carry out industrial production engineering
In generated exhaust gas, pulmonary emphysema contain a large amount of sulfur dioxide, the pernicious gases such as nitrogen oxides, in order to discharge enterprise
Gas meets the environmental requirement of country, just must carry out desulphurization denitration processing to exhaust gas.
In desulphurization and denitration and cooling system now, neutralisation is mostly used, i.e., by debita spissitudo ammoniacal liquor or lye etc.
Liquid medium is injected to required position and waste gas reaction with spray gun, and spray gun used is in the majority with double-current spray gun body, and hybrid mode is also big
All being mixed using internal-mixing, the fluid media (medium) of double-current spray gun body is generally air and a kind of liquid, when work, the pressure of certain pressure
The liquid medium of contracting air and certain pressure is supplied to spray gun, and liquid-to-air multiple impacts, mixing, atomization generate little particle,
Little particle is contacted with high-temperature flue gas, is reacted, what is reduced the content of pernicious gas from.
But in actual production engineering, the concentration of pernicious gas is time to time change in flue gas, so liquid is situated between
The concentration of matter is just also wanted to change with the concentration of pernicious gas and change, moreover, can require two kinds simultaneously in some special industries
Or sprayed after the mixing of plurality of liquid medium, currently, spray gun used in China's industry is double-current spray gun body, that is to say, that remove
Outside compressed air, a kind of atomized spray of liquid can only be realized, although the method for being again passed through spray gun after mixing can also be taken,
But this needs external storage device again, expends space and increases cost, and if being passed through spray gun again after mixing, in time
Have it is certain delay, can not in real time for detection concentration of harmful substance, influence eliminate pernicious gas effect, this is current work
Urgent problem in industry.
The spray gun of internal-mixing is to apply most burner nozzle constructeds now, but there are distinct disadvantages for this spray gun: when more
When kind fluid is passed through spray gun simultaneously, when the pressure of one of fluid is excessive, biggish change can also occur for remaining fluid
Change, because internal-mixing spray gun nozzle multiple fluid is mixed in spray tip, when a kind of Fluid pressure is excessive, will stop very
To the ejection for being remaining fluid of blocking, such case can largely effect on the effect of injection, mixing, atomization, cause damages.
Summary of the invention
It is an object of the invention to provide a kind of three Fluid sprayer spray heads of novel exterior mixing for overcoming drawbacks described above.
To achieve the above object, the present invention takes following scheme: a kind of three Fluid sprayer spray head of exterior mixing, including spray head sheet
Body, air cap, the first tapered sleeve, the second tapered sleeve, washer, guard ring, swirl vane (1), swirl vane (2), swirl vane (3), institute
It states and is respectively equipped with first fluid channel, second fluid channel and third fluid channel in head body.
Preferably, the spray head sets up first runner centered on central axis, the outer nesting first of the first runner is bored
Set, sets up second flow channel outside first tapered sleeve, outer nested second tapered sleeve of the second flow channel, and the is set up outside second tapered sleeve
Three runners, the outer nested air cap of the third flow channel.
Preferably, the first fluid channel is vertical core, number is one, and second fluid channel is inclined hole, and number is
Six, and be uniformly distributed circumferentially relative to central axes, third fluid channel is inclined hole, and number is six, and relative to axis
Line is uniformly distributed circumferentially.
As preferred: the first fluid channel, second fluid be logical, is provided with eddy flow leaf in third fluid channel
Piece.
Also, the rotation direction of first fluid channel inward eddy blade is oppositely oriented with second fluid channel inward eddy blade,
The rotation direction of first fluid channel inward eddy blade is identical as the rotation direction of third fluid channel inward eddy blade.
Three Fluid sprayer head body of exterior mixing provided by the invention is set there are three independent runner, can be passed through three simultaneously
Kind fluid, can according to need the flow by adjusting liquid medium in use to change the proportion of mixing liquid, or change
Become the concentration of liquid medium.
Swirl vane is increased in fluid course of the invention, fluid can generate high speed rotation when passing through swirl vane,
When fluid is sprayed from runner mouth, fluid forms wide-angle conical hollow, and fluid has just been atomized at this time, and wherein first fluid is logical
Road is identical as the rotation direction of swirl vane in third fluid channel, and first fluid channel and second fluid channel inward eddy blade revolve
To on the contrary, high-speed rotating fluid collides when spraying from runner, generation secondary-atomizing is simultaneously mixed, and generates more small mist
The problem of changing particle, overcoming internal-mixing atomizing spray gun sprayer.
The beneficial effects of the present invention are: three Fluid sprayer pipette tips of exterior mixing can make three kinds due to the change of internal structure
Fluid is passed through spray gun simultaneously, and three kinds of fluids are sprayed from into spray gun spray nozzle to from spray gun spray nozzle, are in independent stream always
In road, atomization and mixed process are carried out outside spray head, and the pressure flow variation of any fluid does not interfere with it
He two kinds pressure flow variation, to ensure that atomizing effect.
