Description

Technical Field

[0001] This utility model relates to the field of biological deodorization towers, and in particular to a multi-stage biological deodorization tower. Background Technology

[0002] Biological deodorization towers are environmentally friendly equipment that utilizes the metabolic activity of microorganisms to degrade malodorous gases. They are widely used in sewage treatment plants, garbage disposal sites, farms, and other places. Their core principle is that the biofilm formed by microorganisms on the surface of the packing material decomposes pollutants such as hydrogen sulfide, ammonia, and volatile organic compounds into harmless substances such as carbon dioxide and water.

[0003] Currently, there are some multi-stage biological deodorization towers on the market, mainly composed of a pre-washing section, a biological treatment section, and a demisting section. Among them, the biological treatment section is the core treatment area inside the tower, occupying most of the area inside the tower. The biological treatment section mainly consists of a liquid spraying structure, biological packing material, and a grid plate supporting the packing material. However, the nozzles in the liquid spraying structure are mostly fixed structures. In actual use, users may sometimes encounter certain dead zones during spraying due to adjustments in the height of the packing material or other reasons, resulting in the biological treatment effect failing to meet the standards. Traditional spraying structures of this type are not convenient for users to flexibly and quickly adjust the number and position of the nozzles, and the design is not reasonable enough.

[0004] Therefore, it is necessary to provide a new multi-stage biological deodorization tower to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a multi-stage biological deodorization tower that allows users to flexibly adjust the number and position of the nozzles in the biological treatment zone, thereby achieving more uniform and reasonable coverage of the liquid.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-stage biological deodorization tower, comprising: a deodorization tower body, a treatment zone spraying structure, and a pre-humidification zone spraying structure. The deodorization tower body includes a tower body, and a first grid plate, a second grid plate, and a third grid plate are distributed sequentially from left to right inside the tower body. The pre-humidification zone spraying structure is installed on the inner wall of the tower body above the first grid plate, and the treatment zone spraying structure is installed on the inner wall of the tower body above the second grid plate.

[0007] The spraying structure of the treatment area includes two guide rails, each fixedly connected to the inner walls of the front and rear side walls of the tower body on the upper side of the second grid plate. A communicating vessel is fixedly connected to the inner wall surface of the tower body located on the upper side of the guide rails. Several output pipes evenly distributed laterally are fixedly connected to the surface of the communicating vessel. The output pipes communicate with the interior of the communicating vessel, and valve bodies are fixedly connected to the ends of the output pipes. Several support rods are arranged inside the tower body located between the two guide rails. Slider blocks are fixedly connected to both ends of each support rod. The sliders are slidably connected to the guide rail on the adjacent side. Several movable sleeves are slidably connected to the surface of the support rods. Fixed pipes are fixedly connected to the outer circumference of each movable sleeve. Spray head two is fixedly connected to the bottom of each fixed pipe. The top of each fixed pipe is fixedly connected to the end of the valve body on the adjacent side through a flexible hose. Several positioning holes evenly distributed laterally are opened on the surface of the guide rails. A set screw one is threadedly connected to the surface of the slider. One end of the set screw one is inserted into the positioning hole on the adjacent side. A set screw two is threadedly connected to the surface of the movable sleeve. The end of the set screw two located inside the movable sleeve abuts against the outer circumference of the support rod.

[0008] As a further embodiment of this utility model, the bottoms of the first grating plate, the second grating plate, and the third grating plate are all fixedly connected to the inner wall of the bottom of the tower body by support columns. A discharge pipe one is fixedly connected to the rear wall surface of the tower body located below the first grating plate, and a discharge pipe two is fixedly connected to the rear wall surface of the tower body located below the second grating plate and the third grating plate. Both the discharge pipe one and the discharge pipe two are connected to the interior of the tower body.

[0009] Through the above technical solution, the first and second grid plates are used to place the packing materials corresponding to the pre-wetting zone and the biological treatment zone, while the third grid plate is used to place the demister. In addition, the discharge pipe one is used to connect to the external valve or pipeline to discharge the sewage from the pre-wetting zone, and the end of the discharge pipe two also needs to be connected to the external pipeline or valve, which is used to discharge the liquid sprayed by the spraying structure in the treatment zone.

[0010] As a further embodiment of this utility model, a partition plate one is fixedly connected to the inner wall of the top of the tower body located between the first grid plate and the second grid plate, a partition plate two is fixedly connected to the inner wall of the bottom of the tower body located on the side of the partition plate one near the second grid plate, and a partition plate three is fixedly connected to the inner wall of the top of the tower body located between the second grid plate and the third grid plate. The partition plate three is fixedly connected to both the second grid plate and the third grid plate, the partition plate two is fixedly connected to the second grid plate, and the partition plate one is fixedly connected to the first grid plate.

[0011] With the above technical solution, when the inlet pipe is connected to the external odor gas pipeline and the outlet pipe is connected to the external fan, the gas enters from the inlet pipe, passes through the channel composed of partition one and partition two, enters the area between partition two and partition three, and finally passes through the lower side of partition three and is discharged from the outlet pipe.

[0012] As a further embodiment of this utility model, inspection pipes are fixedly connected to the front wall surfaces of the tower body located on the upper and lower sides of the first grating plate, the second grating plate, and the third grating plate, as well as to the top of the tower body located above the second grating plate. The inspection pipes are connected to the interior of the tower body, and a viewing window is fixedly connected to the surface of the inspection pipes.

[0013] Through the above technical solution, the function of the inspection pipe is to facilitate the maintenance of the tower's interior by the staff, and the function of setting the viewing window is to seal the inspection pipe under normal circumstances, while also facilitating the staff's observation.

[0014] As a further embodiment of this utility model, the pre-wetting zone spraying structure includes two side connecting pipes distributed front to back, both of which are fixedly connected to the inner wall of the tower body on the upper side of the first grid plate, and a plurality of nozzles are fixedly connected to the surface of the side connecting pipes.

[0015] With the above technical solution, the ends of both sets of side connecting pipes extend to the outside of the tower body to connect with external water pipes and pumps and other equipment. One nozzle will spray water to pre-wet the odorous gas in the area. In addition, since this structure is used for biological treatment of odorous gas, each component must be manufactured to ensure good corrosion resistance.

[0016] As a further embodiment of this utility model, an air inlet pipe is fixedly connected to the top surface of the tower body located above the first grating plate, and an air outlet pipe is fixedly connected to the top surface of the tower body located above the third grating plate. Both the air inlet pipe and the air outlet pipe are connected to the interior of the tower body.

[0017] With the above technical solution, the intake pipe is used to connect to the external odor gas pipeline, while the exhaust pipe is used to connect to external equipment such as fans.

[0018] Compared with related technologies, the multi-stage biological deodorization tower provided by this utility model has the following beneficial effects:

[0019] To improve the spray coverage and treatment effect of the biological treatment area during actual use, a spray structure is specially designed on the upper side of the second grid plate. Sprayer head two is fixed to one side of a movable sleeve, which can slide back and forth on the support rod. After adjusting the spacing between the movable sleeves on the support rod, the user can tighten the set screw two for fixation. To adjust the spacing between adjacent support rods, the slider can be slid laterally to the appropriate position, and then the slider position can be finely adjusted so that the end of set screw one aligns with the positioning hole on the adjacent side. Finally, set screw one is tightened in. This design allows users to quickly adjust the spacing and position of each sprayer head two, ensuring more even coverage of the area. It is also convenient and easy to use. Attached Figure Description
