Abstract
The utility model discloses a denitration spray gun, which comprises a gun body with a through hole, a connecting part arranged at one end of the gun body, and a nozzle arranged at the other end of the gun body, wherein an air joint into which compressed air is introduced and an ammonia joint into which ammonia is introduced are arranged on the connecting part, and the air joint is internally provided with an air through hole for compressed air to flow and has an aperture of 1.2-5mm; the end part of the air joint is provided with a tapered part, and the connecting part is internally provided with a tapered hole; a venturi structure is formed between the tapered part and the tapered hole, and an ammonia channel is arranged between the air joint and the connecting part; the ammonia through hole of the ammonia joint is communicated with the ammonia channel. By reducing the aperture of the air through hole, the flow speed of the compressed air is further increased; through the venturi structure between the air joint and the connecting part, the situation that the ammonia can not be sprayed out due to too high pressure of the compressed air can be effectively prevented; the structure is simple, and the test shows that the spray gun has a range of up to 5.5m and a width of 2m.
Description
Technical field
The utility model relates to a kind of denitration spray gun.
Background technology
In prior art for the spray gun of denitration, and structure generally comprises the rifle body with through hole, be arranged at the connecting portion of described Qiang Ti one end, be arranged at the nozzle of the described rifle body other end, on described connecting portion, be provided with the ammoniacal liquor joint that passes into compressed-air actuated pneumatic fitting and pass into ammoniacal liquor, conventionally the air hole aperture on pneumatic fitting is larger, therefore cause compressed air pressure less, make the range of spray gun shorter, can not reach use standard, while increasing compressed air pressure in addition, easily cause spray not go out the situation of ammoniacal liquor, affect whole denitrating technique.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of denitration spray gun is provided, and improves jet length, and can obtain suitable jet angle.
For achieving the above object, the technical solution of the utility model has been to provide a kind of denitration spray gun, comprise the rifle body with through hole, be arranged at the connecting portion of described Qiang Ti one end, be arranged at the nozzle of the described rifle body other end, on described connecting portion, be provided with the ammoniacal liquor joint that passes into compressed-air actuated pneumatic fitting and pass into ammoniacal liquor, in described pneumatic fitting, there is the air hole of passing through for compressed air, the aperture of described air hole is 1.2-5mm, the end of described pneumatic fitting has tapered portion, in described connecting portion, offer bellmouth, between described tapered portion and described bellmouth, form Venturi tube structure, between described pneumatic fitting and described connecting portion, there is ammoniacal liquor passage, the ammoniacal liquor through hole of described ammoniacal liquor joint is connected with described ammoniacal liquor passage.
As preferably, described air hole parallels with described through hole, and described ammoniacal liquor through hole and described through hole are perpendicular.
As preferably, described air hole is mutually concentric with described through hole.
As preferably, on described rifle body, be provided with reinforcement gusset.
As preferably, described nozzle is atomizer.
As preferably, on described pneumatic fitting, be provided with the first screwed hole being connected with described air hole, on described ammoniacal liquor joint, be provided with the second screwed hole being connected with described ammoniacal liquor through hole.
As preferably, between described air hole and described the first screwed hole, be provided with conical bore.
As preferably, described rifle body is telescoping tube.
Advantage of the present utility model and beneficial effect are: by the aperture of air hole is changed little, further improve compressed-air actuated flow velocity, and by the Venturi tube structure arranging between pneumatic fitting and connecting portion, can effectively prevent that compressed air pressure is excessive and cause spray to misfire the situation of ammoniacal liquor, simple in structure, range through test spray gun reaches 5.5m, and widely can reach 2m.
