Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater deodorization device. Background Technology

[0002] During wastewater treatment, the decomposition of organic matter produces large amounts of malodorous gases such as hydrogen sulfide, ammonia, and mercaptans. Direct emission of these gases can severely pollute the surrounding atmosphere and harm human health. Therefore, odor collection and purification of wastewater treatment facilities are crucial.

[0003] According to the search, Chinese utility model patent CN217297335U discloses a typical sewage deodorization device, which adopts a separate mixing tank and deodorization tank. The odor is drawn into the deodorization tank by an air pump and purified by a rotating deodorization plate.

[0004] However, this device suffers from a core flaw that leads to its unsatisfactory deodorization effect: the internal flow field design of its deodorization chamber is unreasonable, resulting in significant gas "short-circuit" paths. Specifically, after the odorous gas is delivered into the deodorization chamber through the pipes, the combined effect of the suction force of the air pump and the wind force generated by the rotation of the deodorization plates causes the gas to easily flow to the exhaust port via the shortest path, failing to make sufficient and effective contact with the rotating deodorization plates. This results in some of the odorous gas being discharged directly from the system untreated or incompletely treated, causing secondary pollution. Furthermore, the device requires three independent power sources to achieve stirring, gas delivery, and deodorization plate rotation, making its structure complex and energy-intensive.

[0005] Therefore, there is an urgent need in this field for a new deodorization device structure that can fundamentally eliminate gas "short circuits" and ensure that all odorous gases must be fully purified. Utility Model Content

[0006] The purpose of this invention is to overcome the aforementioned technical difficulties and provide a wastewater deodorization device with a more effective deodorization effect.

[0007] To achieve the above objectives, the technical solution adopted is as follows: a sewage deodorization device, including a mixing tank, wherein the top of the mixing tank is provided with an air intake and is connected to a deodorization tower body via a connecting pipe and an air pump, wherein the deodorization tower body includes a filtration chamber and a fine filtration chamber connected sequentially from top to bottom; The filter chamber includes an openable housing and two cyclone turbines connected in series within the housing, with the outlet of the upper cyclone turbine facing the inlet of the lower cyclone turbine. Both of the aforementioned cyclone turbines have removable filter plates installed on the inner walls of their turbine housings; A modular deodorizing cylinder is vertically installed inside the fine filtration chamber. Its top is connected to the air outlet of the lowest layer of the cyclone turbine, and its bottom or lower side has an exhaust port.

[0008] Furthermore, the housing includes an openable front cover, which is sealed to the housing via a quick-lock flange.

[0009] Furthermore, a rotating shaft is connected between the two cyclone turbines, and the rotating shaft between the cyclone turbines is connected to the drive mechanism via a quick-release coupling.

[0010] Furthermore, the detachable filter plate has a fan-shaped plate structure, and the inner wall of the turbine housing is provided with a sliding rail that cooperates with it, so that the filter plate can be pulled out along the vertical direction of the turbine.

[0011] Furthermore, the modular deodorizing cylinder includes an outer cylinder and at least one hollow inner cylinder coaxially disposed therein.

[0012] Furthermore, the hollow inner cylinder is detachably disposed on the inner wall of the outer cylinder, and the surface of the hollow inner cylinder is provided with filter material.

[0013] Furthermore, a detection gate is provided on the outer wall of the fine filtration chamber.

[0014] Furthermore, a water collection tank is provided at the bottom of the fine filtration chamber, and the water collection tank is connected to a drain pipe.

[0015] The beneficial effects of adopting the above solution are as follows: This sewage deodorization device eliminates gas bypass, ensuring thorough and reliable purification. This invention connects two cyclone turbines in series, directly linking them to a vertically arranged modular deodorization cylinder, forming a top-to-bottom vertical purification path. This structure ensures that after leaving the bottom cyclone turbine, the gas must completely penetrate the entire deodorization cylinder from top to bottom before being discharged from the exhaust port. This design physically forces all gas to fully contact the deodorizing medium, completely solving the problem of some gas being discharged directly without treatment due to airflow "short-circuiting" in traditional deodorization boxes, thus ensuring thorough and reliable purification.

[0016] Achieving two-stage synergistic purification to improve treatment efficiency: The device constitutes a highly efficient two-stage synergistic purification system of "cyclone filtration + penetrating fine filtration". In the first stage, odorous gas collides and is intercepted by detachable filter plates inside the turbine housing in the complex flow field formed by the cyclone turbines connected in series, completing preliminary purification. In the second stage, the gas penetrates the entire modular deodorization cylinder in the fine filtration chamber for deep and slow fine filtration. The two stages are seamlessly connected and work synergistically to significantly improve the overall deodorization efficiency.

[0017] Easy maintenance and continuous operation: Key components of this invention have been optimized for maintainability. The filter chamber features an openable shell, fully exposing the internal structure; the filter plates inside the cyclone turbine shell are removable via sliding rails, enabling quick replacement and cleaning. Simultaneously, an inspection door is provided on the outer wall of the fine filtration chamber, facilitating inspection and replacement of the internal modular deodorization cartridge. This design greatly simplifies the maintenance process, reduces maintenance costs, and ensures long-term, continuous, and stable operation of the equipment. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Example 1 See Figures 1 to 4 The wastewater deodorization device provided by this utility model mainly consists of three parts: a mixing tank 1, a conveying unit, and a vertical deodorization tower.

[0025] The mixing tank 1 is the initial site for wastewater treatment, and it has an air intake at the top. A conventional stirring impeller driven by a motor can be installed inside the mixing tank 1 to agitate the wastewater and promote the full escape of odors. The escaped odors concentrate in the space at the top of the tank.

[0026] The conveying unit is responsible for transporting the odorous gas from the mixing tank 1 to the deodorization tower. This unit includes a connecting pipe 2 and an air pump 3. One end of the connecting pipe 2 is connected to the air intake at the top of the mixing tank 1, and the other end is connected to the air inlet of the air pump 3. The air outlet of the air pump 3 is connected to the air inlet at the top of the deodorization tower.

[0027] The deodorization tower is the core component for gas purification. It adopts a vertical layout, with a filter chamber 5 and a fine filter chamber 6 arranged from top to bottom. The two are fixedly connected and internally interconnected.

[0028] The filter chamber 5 performs the primary purification function. Its housing is an openable, sealed chamber, specifically composed of a fixed main body and an openable front cover. The front cover is quickly locked and sealed to the main body via a quick-lock flange 7. Inside the chamber, two cyclone turbines 9 are arranged in series, one above the other. The two cyclone turbines 9 are connected by a through-type rotating shaft that extends to the outside of the tower body and is connected to the drive mechanism 12 (commonly a motor) via a quick-release coupling. Each cyclone turbine 9 has a removable filter plate 15 on its inner wall. For easy disassembly, the inner wall of the turbine housing is provided with a slide rail 4, and the filter plate 15 is a fan-shaped plate structure that can be pushed in or pulled out along the slide rail 4. Multiple fan-shaped filter plates 15 are combined to form a complete annular filter surface surrounding the turbine.

[0029] The fine filtration chamber 6 performs secondary deep purification. One or more inspection doors 8 are provided on its outer wall for easy observation and maintenance. A modular deodorizing cylinder is vertically installed inside the fine filtration chamber 6. This deodorizing cylinder consists of an outer cylinder 13 and one or more perforated inner cylinders 10 coaxially fitted inside it. The perforated inner cylinder 10 is detachably installed inside the outer cylinder 13, its wall is covered with mesh or slits, and its surface is loaded or its interior is filled with filter materials such as activated carbon or zeolite. Multiple annular chambers filled with deodorizing media are formed between the outer cylinder 13 and the perforated inner cylinders 10, as well as between adjacent perforated inner cylinders 10.

[0030] In practice, an air outlet pipe 11 is provided between the lower cyclone turbine 9 and the fine filter chamber 6.

[0031] The specific implementation method is as follows: Wastewater is stirred in the mixing tank 1, and the escaping odorous gas collects at the top and is transported by the air pump 3 through the connecting pipe 2 to the filter chamber 5 at the top of the deodorization tower. The gas first passes through two cyclone turbines 9 connected in series, which are accelerated and form violent turbulence. During this process, the gas undergoes forced and full collision and contact with the filter plates 15 on the inner wall of the cyclone turbine 9 housing, completing the first stage of dust removal, demisting, and preliminary deodorization. Subsequently, the gas is discharged from the bottom cyclone turbine 9 through the exhaust pipe 11 and directly enters the top of the fine filtration chamber 6, penetrating the entire vertically arranged modular deodorization cylinder from top to bottom. During this process, the gas undergoes deep reaction and adsorption with the filter media in the deodorization cylinder, achieving thorough purification. Finally, the clean gas collects at the bottom of the fine filtration chamber 6 and is discharged through the exhaust port 14 in compliance with standards.

[0032] Example 2 Based on Embodiment 1, the applicant considered that liquid accumulation might occur inside the filtration chamber 5 and the fine filtration chamber 6 during prolonged operation. Therefore, a water collection tank is provided at the bottom of the fine filtration chamber, and the water collection tank is connected to a drain pipe. This is used to promptly remove any condensate that may be generated and prevent liquid accumulation inside the chamber.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
