Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, specifically relating to a deodorization system. Background Technology

[0002] In feed production, materials undergo complex chemical reactions such as the Maillard reaction during maturation under high temperature (80-120°C) and high pressure. While this produces aroma, it also generates malodorous substances containing sulfur and nitrogen. Herbal deodorizers are natural active ingredients (such as terpenes and phenolic compounds) extracted from plants like tea trees, eucalyptus trees, mint, and citrus fruits. These deodorizers can break down the molecular structure of malodorous substances, oxidizing and decomposing them into harmless substances, or reacting chemically with specific odor molecules to generate odorless substances.

[0003] The deodorizing method involves spraying a diluted herbal deodorizing solution onto the odor-causing agent to react with it. However, current technologies typically use a one-time spraying method to react with the odor-causing agent and then expel the odor, resulting in poor deodorizing effectiveness. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a deodorization system that aims to solve the problem in the prior art where the odor is reacted with by a one-time spray and then discharged, resulting in poor deodorization effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1 This utility model provides a deodorization system, including a spray tower 1, a spray pool 2, and an exhaust pipe 3. The air inlet of the spray tower 1 is connected to a first fan 11, which is used to input odor into the spray tower 1. The spray tower 1 is provided with a first spray pipe 12. The air outlet of the spray tower 1 is connected to the air inlet of the spray pool 2 through a second fan 21. The spray pool 2 is provided with a second spray pipe 22. The air outlet of the spray pool 2 is connected to the exhaust pipe 3 through a third fan 31. The exhaust pipe 3 is provided with a third spray pipe 32. The first spray pipe 12, the second spray pipe 22, and the third spray pipe 32 are used to spray diluents of different concentrations, and the concentration of the diluents increases sequentially.

[0019] In this application, spray tower 1 receives exhaust gas collected from the production workshop, at which point the odor concentration is at its highest, but the majority of it consists of "free" odor molecules that readily react with the deodorizing agent. Even with a low concentration of deodorizing agent dilution, the large contact area and concentration difference allow for efficient capture and neutralization of most odor molecules under high odor concentration conditions. The reaction rate is fast, resulting in high removal efficiency. In spray tower 1, the high-load odor is reduced to a lower level, thus protecting the subsequent spray tank 2 and exhaust pipe 3 from rapid contamination or saturation. Furthermore, using a low-concentration deodorizing agent dilution reduces raw material costs.

[0020] The remaining odor molecules in the exhaust gas after treatment by spray tower 1 may be components with slightly lower reactivity or those that require a longer time to remove. Using a medium concentration of deodorizer can provide stronger chemical power for deep purification, ensuring further improvement in exhaust gas quality.

[0021] The exhaust gas reaching the spray pipe already has a low total odor level, but what remains are often the most difficult-to-treat substances (such as some thiols and volatile organic compounds), which may be encapsulated by aerosols or adsorbed onto particles. For these substances, a higher concentration of deodorizing agent dilution is needed to ensure thorough contact and reaction, guaranteeing complete reaction and ensuring the final exhaust gas indicators at the outlet.

[0022] According to some embodiments of this utility model, the inlet end of the first spray pipe 12 is connected to a first circulating water pump 13, and the inlet end of the first circulating water pump 13 is connected to the bottom of the spray tower 1. In this embodiment, the first circulating water pump 13 can extract the deodorant dilution accumulated at the bottom of the spray tower 1 and transport it to the first spray pipe 12 for re-spraying, thereby realizing the recycling of the deodorant dilution and improving resource utilization.

[0023] According to some embodiments of this utility model, the spray tower 1 is provided with a first packing material 14. In this embodiment, the first packing material 14 has a complex porous structure, which allows the sprayed deodorant dilution liquid to spread into an extremely thin liquid film on its surface, thereby providing a huge contact area for the gas and liquid phases and enabling the reaction to proceed efficiently. In addition, when the exhaust gas passes through the tortuous path of the first pile, its speed will slow down, forcing it to repeatedly collide and contact with the surface of the packing material covered with the deodorant dilution liquid, greatly prolonging the reaction time between the odor molecules and the deodorant. Specifically, the first packing material 14 can be made of ceramic packing material, which can handle the high-temperature gas just discharged from the workshop.

[0024] According to some embodiments of this utility model, the inlet end of the second spray pipe 22 is connected to a second circulating water pump 23, and the inlet end of the second circulating water pump 23 is connected to the bottom of the spray tower 1. Similarly, in this embodiment, the second circulating water pump 23 can extract the deodorant dilution accumulated at the bottom of the spray tank 2 and transport it to the second spray pipe 22 for re-spraying, thereby realizing the recycling of the deodorant dilution and improving resource utilization.

[0025] According to some embodiments of this utility model, the spray tank 2 is provided with a second packing material 24. In this embodiment, the second packing material 24 can be PP (polypropylene) packing material to reduce costs.

[0026] According to some embodiments of the present invention, the inlet end of the third spray pipe 32 is connected to a filter assembly.

[0027] Specifically, the filtration assembly includes a third water pump 41, a first filter tank 42, a second filter tank 43, and a dilution tank 44. The dilution tank 44 is connected between the first filter tank 42 and the third water pump 41. A first valve 51 is provided between the inlet of the first filter tank 42 and the dilution tank 44. A second valve 52 is provided between one outlet of the first filter tank 42 and the inlet of the second filter tank 43. A third valve 53 is connected to the other outlet of the first filter tank 42. A fourth valve 54 is provided between one outlet of the second filter tank 43 and the inlet of the third spray pipe 32. A fifth valve 55 is provided to the other outlet of the second filter tank 43. The third water pump 41 is also connected to a sixth valve 56, which controls whether the water from the third water pump 41 flows to the outlets of the first filter tank 42 and the second filter tank 43. Since the third spray pipe 32 needs to atomize the high-concentration deodorant dilution, the liquid entering the third spray pipe 32 needs to be filtered to avoid clogging. When the third spray pipe 32 is needed to treat odors, the third water pump 41 is started. During this process, the first valve 51, the second valve 52, and the fourth valve 54 are opened, while the third valve 53, the fifth valve 55, and the sixth valve 56 are closed. The diluted solution flows sequentially through the first filter tank 42 and the second filter tank 43 for filtration. When the third spray pipe 32 is needed to treat odors, the third water pump 41 is started. During this process, the first valve 51, the second valve 52, and the fourth valve 54 are closed, while the third valve 53, the fifth valve 55, and the sixth valve 56 are opened. The water from the third water pump 41 backwashes the first filter tank 42 and the second filter tank 43, cleaning them.

[0028] According to some embodiments of this utility model, the liquid outlet end of the third spray pipe 32 is connected to an atomizing nozzle 45. In this embodiment, the atomizing nozzle 45 can atomize the high-concentration deodorant dilution delivered from the third spray pipe 32, causing the deodorant dilution to form tiny droplets. These tiny droplets can more fully contact and react with the remaining odor molecules in the exhaust gas, further improving the deodorization effect. Moreover, the atomizing nozzle 45 makes the spraying range of the deodorant dilution wider and more uniform, ensuring that all areas within the exhaust pipe 3 receive effective deodorization treatment.
