Description

Technical Field

[0001] This utility model relates to the field of air source distribution box technology, and in particular to a compressed air distribution device for an SNCR denitrification system. Background Technology

[0002] Gas distribution boxes are key equipment in gas supply systems, mainly used to rationally distribute a single gas source to multiple gas consumption points. They typically consist of a robust housing, precision valves, pressure regulating devices, and connecting pipes, effectively integrating gas sources and ensuring stable and uniform gas delivery. In industrial production, they can meet the gas requirements of different equipment and improve production efficiency. In laboratories and other locations, they can provide reliable gas source support for various instruments. In SNCR denitrification systems, gas distribution boxes are used to distribute compressed air.

[0003] When using a gas distribution box, a pipe needs to be connected at the input end to receive gas. However, the current input end has a significant defect: the lack of a filter structure. This allows air containing particulate matter and oil mist to enter the gas distribution box without hindrance. These impurities can cause serious damage. Particulate matter acts like sandpaper, constantly abrading the precision equipment inside the box; oil mist gradually adheres and accumulates, eventually causing blockages. Once blockages occur, the gas distribution box cannot operate normally and cannot stably supply gas to the points of use, thus greatly reducing its original performance and affecting the operation of the entire gas supply system.

[0004] Therefore, in response to the above problems, a new compressed air distribution device for SNCR denitrification systems is proposed. Utility Model Content

[0007] Furthermore, the filter assembly includes a rubber sleeve, an assembly housing, a particulate filter, and an activated carbon filter block; The gas source distributor has rubber sleeves installed at equal intervals inside the support frame at the input end. Assembly shells are symmetrically installed inside the rubber sleeves. A particulate filter is installed inside the assembly shell. An activated carbon filter block is located inside the assembly shell on one side of the particulate filter.

[0008] Furthermore, symmetrical positioning holes are provided on the assembly shell, and positioning blocks are symmetrically fixedly connected to both the particulate filter and the activated carbon filter block, with the positioning blocks slidably connected to the positioning holes.

[0009] Furthermore, the width of the support frame entrance is greater than the diameter of the rubber sleeve.

[0010] Furthermore, a lifting seat is installed inside the support frame, the upper surface of the lifting seat is in contact with a rubber sleeve, a lifting rod is slidably connected to the inner wall of the support frame and fixedly connected to the lower surface of the lifting seat, and a spiral rod is rotatably connected to the inner wall of the support frame and meshes with the inside of the lifting rod.

[0011] Furthermore, a transmission rod is rotatably connected to one side of the support frame, and one end of the transmission rod is connected to the bottom end of the screw rod through a bevel gear meshing.
