Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1 to 4, the pressure-stabilizing injection-type automatic powder spraying device for waste gas treatment provided by the utility model comprises a main injection pipe 1, an injection sleeve pipe 2, a powder sprayer discharge pipe 3, a powder sprayer 4, an air blower air outlet pipe 5 and an air blower 7, wherein the air blower 7, the air blower air outlet pipe 5, the injection sleeve pipe 2 and the main injection pipe 1 are supported by a support 6.
