Abstract
Description
Technical Field
[0001] The utility model relates to the field of spray scrubbers, in particular to a novel packed bed spray scrubber. Background Art
[0002] Generally, spray scrubbing can be used successfully to solve odor pollution and large solid particles, but the effect on smoke treatment is not ideal. Odor elimination can be achieved by adding acidic substances or oxidants (such as sodium hypochlorite and chlorine dioxide) to the spray liquid. By oxidizing large molecular organic matter, the odor can be eliminated. The packed bed scrubber allows the spray liquid and exhaust gas to be in full contact, which can reduce the amount of spray liquid used and ensure a high removal efficiency. Ordinary fillers are mostly made of highly breathable plastics and ceramics with special shapes. For the exhaust gas from dyeing and finishing machines, the packed bed scrubber can effectively cool it and has a certain removal efficiency. However, when there are many oil smoke particles in the exhaust gas, the oil smoke particles condense and adhere to the filler. After a long period of operation, it is bound to become blocked.
[0003] Therefore, it is necessary to design a new type of packed bed spray scrubber. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a novel packed bed spray scrubber.
[0005] The utility model provides a new type of packed bed spray scrubber adopts the following technical solutions:
[0006] A new type of packed bed spray scrubber includes a tower body, a packing assembly, a spray assembly, an air inlet and an air outlet. The packing assembly and the spray assembly are arranged in the tower body, the air inlet is arranged on the side of the tower body close to the bottom, the air outlet is arranged at the top of the tower body, the packing assembly is arranged below the spray assembly, and the packing assembly includes a fixing frame and packing rods. The fixing frame is provided with two groups, and the two ends of the packing rods are respectively connected to the fixing frame, and there are gaps between the packing rods.
[0007] Optionally, the filler assembly includes a fixing frame, an elastic rope and filler balls, two ends of the elastic rope are respectively connected to the fixing frame, and a plurality of filler balls are provided on the elastic rope.
[0008] Optionally, the filler balls are glass beads or ceramic balls.
[0009] Optionally, two groups of the spraying components and two groups of the filling components are provided.
[0010] Optionally, the spray assembly includes a circulating water inlet, a spray pipe, and a mist nozzle. The circulating water inlet is arranged on the side wall of the tower body, the spray pipe is connected to the circulating water inlet, and the spray pipe is provided with a plurality of mist nozzles.
[0011] Optionally, a circulating liquid outlet is provided at the bottom of the tower body.
[0012] In summary, the present invention has at least one of the following beneficial technical effects:
[0013] 1. Replace the packing with a multi-rod type, so that the gas and spray liquid compete for space in the solid tubular structure, causing intense mixing. In this way, the condensed oil mist is not easy to adhere to it, thus avoiding the occurrence of clogging;
[0014] 2. The packing is spherical. The interaction between the gas, the spray liquid, and the stacked solid glass or ceramic balls creates a continuous channel, effectively treating the exhaust gas. The continuous rotation of the glass or ceramic balls removes any grease adhered to them, keeping the surface clean for a longer period of time. Furthermore, when treating odorous exhaust from dyeing and finishing machines, a biological packing tower can be used. This achieves excellent deodorization at a lower cost while also effectively preventing secondary pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
