Description

Technical Field

[0001] The utility model relates to the technical field of gas recovery in liquor production, in particular to a fan diversion device for treating malodorous gas. Background Technique

[0002] The malodorous gas generated during liquor production mainly comes from the fermentation and distillation stages. During the fermentation process, yeast and other microorganisms decompose organic matter, releasing malodorous gases such as ammonia, hydrogen sulfide, and volatile organic compounds. During the distillation process, high-temperature heating volatilizes compounds such as alcohols, aldehydes, and esters, which emit pungent odors in the air. The fan diversion device for treating malodorous gas is a device used to collect and treat malodorous gas, mainly guiding the malodorous gas from the source to the treatment device through a fan, thereby effectively controlling and eliminating the emission of malodorous gas.

[0003] In the prior art, in order to avoid damage to the blades of the air extraction fan caused by large particle impurities carried in the malodorous gas, a filter screen is often fixedly arranged at the air inlet end of the air extraction fan to intercept large particle impurities. After the filter screen is used for a period of time, it needs to be disassembled for cleaning. However, when the filter screen is installed on the pipeline, it is mostly fixed in the internal pipeline through multiple groups of bolts, resulting in a long overall time-consuming for the disassembly, cleaning, and reinstallation of the entire filter screen, delaying the normal use of the entire diversion device.

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-4 , a fan diversion device for treating malodorous gases includes a loading platform 2. A receiving groove 1 is opened at the top of the loading platform 2. A vertical cylinder 11 is fixedly arranged at the middle position of the top of the loading platform 2. An end cover 110 is fixedly arranged on the side of the vertical cylinder 11 by bolts. A driving motor 6 is fixedly arranged at the central position of the side of the vertical cylinder 11. A common plate 12 is fixedly arranged at the output end of the driving motor 6. The diameter of the common plate 12 is the same as the inner diameter of the cavity of the vertical cylinder 11. The end cover 110 and the vertical cylinder 11 cooperate to wrap and install the common plate 12.

[0021] A circular cavity 9 is opened at the edge position of the side of the common plate 12. A filter wire mesh 8 is fixedly arranged inside the circular cavity 9. An aggregation component for aggregating and guiding malodorous gases is fixedly arranged at the top of the side of the vertical cylinder 11. An end cover 110 is fixedly arranged on the side of the vertical cylinder 11. A backwashing component for facilitating the cleaning of the filter wire mesh 8 is arranged at the bottom of the sides of the vertical cylinder 11 and the end cover 110. The aggregation component includes a collecting hopper 4, a lifting handle 5, and a corrugated pipe 3. A corrugated pipe 3 is fixedly communicated with the top of the side of the vertical cylinder 11. The bottom of the corrugated pipe 3 is fixedly communicated with the collecting hopper 4. The corrugated pipe 3 has elasticity. Workers can take out the collecting hopper 4 from the receiving groove 1 through the lifting handle 5 and move the collecting hopper 4 to the position where malodorous gases are generated.

[0022] The backwashing component includes a sewage outlet pipe 10 and a backwashing pipe 7. The sewage outlet pipe 10 is fixedly connected to the bottom of the side of the vertical cylinder 11. The end cover 110 is fixedly communicated with the backwashing pipe 7 on the opposite side of the sewage outlet pipe 10. The top view cross-sectional shape of the backwashing pipe 7 is zigzag. The top of the backwashing pipe 7 is set in an inverted funnel shape, which is convenient for workers to introduce cleaning water into the backwashing pipe 7. The zigzag setting of the backwashing pipe 7 avoids the blockage of one end of the backwashing pipe 7 by the air outlet pipe 13.

[0023] A handle 5 is vertically and fixedly arranged at the top of the side of the collecting hopper 4. The collecting hopper 4 is movably inserted into the inner part of the receiving groove 1. An air outlet pipe 13 is fixedly communicated with the opposite side of the corrugated pipe 3 on the end cover 110. A horizontal rod 15 is fixedly arranged in the inner cavity of the air outlet pipe 13. An air extraction fan 14 is fixedly arranged on the side of the horizontal rod 15 by bolts. A fan blade is arranged at the vertical end of the air extraction fan 14, which is a common device in the prior art, so it is not disclosed in this application document.

[0024] The specific implementation steps and principles of the present utility model are as follows:

[0025] In the initial state, the worker pulls out the collecting hopper 4 from the inner part of the receiving groove 1 and places it at the position where the malodorous gas source is generated. The air outlet pipe 13 is externally connected to the malodorous gas treatment device. The air extraction fan 14 sucks the malodorous gas into the malodorous gas treatment device through the corrugated pipe 3, the circular cavity 9, and the filter mesh disk 8. When it is necessary to clean the filter mesh disk 8, the driving motor 6 is started. The driving motor 6 drives the filter mesh disk 8 in the circular cavity 9 to move to the side of the sewage discharge pipe 10. The worker introduces a sufficient amount of cleaning water through the reverse cleaning pipe 7, and the cleaning water flushes the dirt intercepted by the filter mesh disk 8 out through the sewage discharge pipe 10.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
