Description
Technical Field
This scheme belongs to denitration technical field, concretely relates to ammonia water spray gun safety structure for denitration.
Background
The combustible materials in the workshop are burnt, excessive NOx is generated to pollute the environment, and denitration treatment is required. In the prior art, an ammonia water spray gun is often used for denitration treatment.
For example, the patent with application number CN201521042263.5 discloses an ammonia water spray gun with an additional protective sleeve, which comprises a spray gun rod, a compressed air injection device and a wear-resistant spray gun head, wherein one end of the spray gun rod is connected with the compressed air injection device, the other end of the spray gun rod is provided with the wear-resistant spray gun head, and the compressed air injection device is provided with a compressed air inlet and an ammonia water inlet; and a material layer which is resistant to scouring, high temperature, abrasion and acid and alkali is sprayed on the wear-resistant spray gun head.
Above-mentioned scheme reduces the easy wearing and tearing of aqueous ammonia spray gun atomizer, the poor problem of high temperature resistant effect through the mode that sets up wear-resisting spray gun head, however, atomizer becomes the scattering mode blowout for perpendicular to flue gas flow direction, easily spouts castable and pipe on the opposite wall body, corrodes the pipe wall.
SUMMERY OF THE UTILITY MODEL
This scheme provides an aqueous ammonia spray gun safety structure for denitration to alleviate denitration equipment's the corruption phenomenon that receives the aqueous ammonia.
In order to achieve the aim, the scheme provides a safety structure of an ammonia water spray gun for denitration, which comprises a spray gun; one end of the spray gun is provided with an air inlet; the other end is provided with a spray head; an ammonia water inlet is arranged on the spray gun, and the spray head is an atomizing spray head; the atomizing nozzle is in a shower shape; the atomizer is 45 direction slopes down, be equipped with the baffle directly over the atomizer, the baffle is fixed to be established on the spray gun, the baffle slope is established on the spray gun.
The principle of the scheme is as follows: the ammonia water is discharged through the ammonia water air inlet, and the compressed air is discharged through the air inlet, so that the atomized ammonia water is sprayed out of the atomizing spray heads, and the denitration effect is achieved.
The beneficial effect of this scheme: the atomizer is the direction slope of 45 degrees down to guarantee that the atomizer is not straight the inner wall that is facing to the denitration equipment of treating, alleviate denitration equipment's corrosion phenomenon. The baffle is arranged right above the atomizing spray head, the baffle is fixedly arranged on the spray gun, the baffle is obliquely arranged on the spray gun, ammonia water sprayed by the atomizing spray head cannot be directly sprayed to a high place, and then the ammonia water returns to the spray gun due to gravity, so that the service life of the spray gun is prolonged.
Furthermore, an anti-corrosion coating is arranged on the baffle to reduce the corrosivity of ammonia water on the baffle.
Furthermore, a heat insulation layer for preventing ammonia water from evaporating is arranged in the spray gun. The effect of heat preservation can prevent the aqueous ammonia evaporation in the spray gun.
Furthermore, an anti-corrosion coating is arranged on the atomizing nozzle to ensure the corrosion resistance of the atomizing nozzle.

Detailed Description
The following is further detailed by way of specific embodiments:
the reference numbers in the drawings attached hereto include: spray gun 1, atomizer 2, air inlet 3, aqueous ammonia air inlet 4, installation department 5, screw hole 6, bolt 7, recess 8, baffle 9.
The embodiment is substantially as shown in figures 1 and 2 and 3:
the left side of spray gun 1 is equipped with air inlet 3, compressed air is discharged into through air inlet 3, the below of spray gun 1 is equipped with aqueous ammonia air inlet 4, discharge into the aqueous ammonia through aqueous ammonia air inlet 4, the right side of aqueous ammonia air inlet 4 is equipped with installation department 5, the upper end of installation department 5 is fixed to be established on spray gun 1, the lower extreme of installation department 5 is equipped with recess 8, recess 8 becomes the door type, be equipped with screw hole 6 on the left surface of installation department 5, screw hole 6 runs through the right flank of installation department 5 from the left surface of installation department 5, bolt 7 can pass from this point, during the use, hang recess 8 on the equipment of treating the denitration, then pass screw hole 6 through bolt 7, fix spray gun 1 with the equipment of treating the denitration.
The right side of spray gun 1 is equipped with atomizer 2, and atomizer 2 is the gondola water faucet form to guarantee that atomizer 2 can spray the aqueous ammonia after the atomizing diversified, the full aspect, the dispersion of many spray in the place that needs the denitration, with the effect of guaranteeing the denitration better, atomizer 2 is downward 45 orientation slope, with guarantee that atomizer 2 is not straight inner wall facing to the denitration equipment of treating, alleviate denitration equipment's corrosion phenomenon. Be equipped with baffle 9 directly over atomizer, baffle 9 is fixed to be established on spray gun 1, and baffle 9 inclines 45 from right side to left and establishes on spray gun 1 to guarantee that the aqueous ammonia that atomizer 2 erupts will not be straight and jet towards the eminence, and then the aqueous ammonia is because gravity gets back to the phenomenon on spray gun 1, increases spray gun 1's life. The baffle 9 is provided with an anticorrosive coating to reduce the corrosiveness of ammonia water to the baffle 9. The inside of the tube body of the spray gun 1 is provided with a heat preservation layer for preventing ammonia water from evaporating. The effect of heat preservation can prevent the evaporation of the aqueous ammonia in 1 body of spray gun.
