Background technology
Present stage, in the denitration industry, the ammonia spirit that denitration is used enters spray gun guarantee denitration efficiency after need to distributing by compressed air and ammonia spirit distributor, but current used compressed air and ammonia spirit distributor volume are large, can't regulate the compressed air that enters spray gun and the amount of ammonia spirit, denitration efficiency is low.
Summary of the invention
The purpose of this invention is to provide a kind of volume little, can accurately control a kind of compressed air and the directed metering of the ammonia spirit distributor of the amount that is metered into the interior compressed air of spray gun and ammonia spirit.
For achieving the above object, the present invention has adopted following technical scheme: the directed metering of described a kind of compressed air and ammonia spirit distributor, comprise: the ammoniacal liquor storage tank, the compressed air caisson, and the denitration reaction device, at least being provided with a coupled logical spray gun of jet pipe on the denitration reaction device, spray gun comprises Liqiud-gas mixing device and jet pipe, offer ammonia spirit import and compressed air inlet on Liqiud-gas mixing device, offer the import of protection gas on jet pipe, each spray gun is connected with the compressed air caisson with the ammoniacal liquor storage tank by a directed metering distributor gear respectively simultaneously, the structure of described directed metering distributor gear is: the ammoniacal liquor storage tank is connected with the ammonia spirit import on Liqiud-gas mixing device in spray gun by the ammoniacal liquor feed tube, feed liquor direction along ammoniacal liquor on the ammoniacal liquor feed tube is disposed with pipeline feed liquor control valve, suspended body flowmeter and pipeline monitoring pressure instrument, the compressed air caisson by two air inlet pipe respectively with Liqiud-gas mixing device on compressed air inlet, and the protection gas import on jet pipe is connected, be disposed with pipeline air inlet adjustment valve along compressed-air actuated airintake direction on every air inlet pipe, compressed air regulating valve and pipeline monitoring pressure instrument.
By the enforcement of technique scheme, the beneficial effect that the present invention has is: volume is little, can accurately control and be metered into the interior compressed air of spray gun and the amount of ammonia spirit, and can improve denitration efficiency.
The accompanying drawing explanation
The operation principle schematic diagram that Fig. 1 is a kind of compressed air of the present invention and the directed metering of ammonia spirit distributor.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, the directed metering of described a kind of compressed air and ammonia spirit distributor, comprise: ammoniacal liquor storage tank 1, compressed air caisson 2, and denitration reaction device 3, at least being provided with a coupled logical spray gun of jet pipe 5 on denitration reaction device 3, spray gun comprises Liqiud-gas mixing device 4 and jet pipe 5, offer ammonia spirit import and compressed air inlet on Liqiud-gas mixing device 4, offer the import of protection gas on jet pipe 5; each spray gun is connected with compressed air caisson 2 with ammoniacal liquor storage tank 1 by a directed metering distributor gear respectively simultaneously, because the structure of each directed metering distributor gear is all identical, the structure of one of them directed metering distributor gear of below only take describes as example, the structure of described directed metering distributor gear is: ammoniacal liquor storage tank 1 is connected with the ammonia spirit import on Liqiud-gas mixing device in spray gun 4 by ammoniacal liquor feed tube 6, feed liquor direction along ammoniacal liquor on ammoniacal liquor feed tube 6 is disposed with pipeline feed liquor control valve 7, suspended body flowmeter 8 and the 3rd pipeline monitoring pressure instrument 17, compressed air caisson 2 is connected with the compressed air inlet on Liqiud-gas mixing device 4 by the first air inlet pipe 9, be disposed with the first pipeline air inlet adjustment valve 10 along compressed-air actuated airintake direction on the first air inlet pipe 9, the first compressed air regulating valve 11 and the first pipeline monitoring pressure instrument 12, and blowing plant 2 is connected with the protection gas import on jet pipe 5 by the second air inlet pipe 13, be disposed with the second pipeline air inlet adjustment valve 14 along compressed-air actuated airintake direction on the second air inlet pipe 13, the second compressed air regulating valve 15 and the second pipeline monitoring pressure instrument 16.In actual applications, accurately control the flow of exporting and enter through ammoniacal liquor feed tube 6 ammonia spirit of Liqiud-gas mixing device 4 from ammoniacal liquor storage tank 1 by pipeline feed liquor control valve 7, monitor piping flow and pressure by suspended body flowmeter 8 and the 3rd pipeline monitoring pressure instrument 17 simultaneously, thereby realize that the orientation metering of ammonia spirit distributes; Accurately control by the first compressed air regulating valve 11 the compressed-air actuated amount of exporting and entering Liqiud-gas mixing device 4 through the first air inlet pipe 9 from compressed air caisson 2, monitor loine pressure by the first pipeline monitoring pressure instrument 12 simultaneously, distribute thereby complete the compressed-air actuated directed metering entered in Liqiud-gas mixing device 4; Accurately control by the second compressed air regulating valve 15 the compressed-air actuated amount of exporting and entering jet pipe 5 through the second air inlet pipe 13 from compressed air caisson 2, monitor loine pressure by the second pipeline monitoring pressure instrument 16 simultaneously, thereby complete the compressed-air actuated amount that enters jet pipe 5.The present invention has that volume is little, and integrated level is high, can accurately control the compressed air that is metered in spray gun and the amount of ammonia spirit, and each pipeline can independently be controlled non-interfering advantage.
