Description

Technical Field

[0001] The utility model relates to the technical field of denitration spray guns, in particular to a rapid vaporization and high-efficiency denitration spray gun. Background Technique

[0002] A denitration spray gun is a device that sprays denitration liquid into flue gas, enabling the denitration liquid to react with nitrogen oxides in the flue gas to achieve the denitration effect.

[0003] In order to improve the denitration effect, compressed gas is injected into the spray gun, so that the compressed gas is mixed with the denitration liquid, enabling the denitration liquid to be in the form of liquid droplets and evenly sprayed into the flue gas.

[0004] Most of the liquid inlet heads of the denitration liquid in the spray gun are fixed to the spray gun by means of threads. Currently, most of the inlet heads are divided into two types. One is that the liquid exits from the top opening, and the other is that the liquid exits from the outer wall of the circumferential side. After the first type of connector is screwed into the spray gun, the liquid outlet direction of the denitration liquid is perpendicular to the axial direction of the spray gun. After the second type of connector is screwed into the spray gun, the liquid outlet angle cannot be determined, resulting in the phenomenon that the compressed gas entering the spray gun enters the liquid flow channel, causing the denitration liquid to be unable to stably enter the spray gun, thereby reducing the working stability of the spray gun.

[0021] The present utility model provides a fast-vaporizing and highly efficient denitration spray gun as shown in Figure 1-2 Figure.

One end of the mixing tube 101 is provided with a spraying mechanism, and the other end is provided with an air inlet mechanism.

Among them, through the cooperation of the compressed gas, the denitration liquid can be turned into fine droplets, increasing its surface area, thereby increasing the contact area with the nitrogen oxides in the flue gas. At the same time, the uniformity of the denitration liquid sprayed into the flue gas is improved, making the denitration efficiency of the flue gas higher.
