Description

Technical Field

[0001] This utility model relates to the field of gas treatment technology for biochemical tanks, and in particular to an odor treatment device for biochemical tanks. Background Technology

[0002] Biochemical technology has become the mainstream technology in wastewater treatment. Currently, wastewater discharge standards are becoming increasingly stringent. To ensure more thorough wastewater treatment, many companies are adopting combined biochemical processes, such as anaerobic-anoxic-aerobic and anaerobic-aerobic processes. However, the anaerobic treatment process generates a large amount of waste gas (volatile organic compounds such as H2S, CH4, and CH3SH). These gases not only cause foul odors at the biochemical system site but also increase the cost of waste gas treatment.

[0003] The existing technology can be referenced from Chinese Patent Publication No. CN215086091U, which discloses a biological waste gas collection and treatment device, including a waste gas pool, a hemispherical cover, a first spray tower, a second spray tower, and a catalytic oxidation device. A first detection device is installed on the side wall of the waste gas pool, and a hemispherical cover (glass cover) is installed at the top of the waste gas pool. An activated carbon bed is installed inside the hemispherical cover. However, this treatment device has a complex overall structure, high load requirements, high power consumption, high operating costs, and is inconvenient for operators and managers. Some treatment devices simply combine multiple treatment units, resulting in bulky equipment and complex piping connections, which not only increases equipment investment costs but also makes operation and maintenance more difficult.

[0004] Therefore, an odor treatment device for biological treatment tanks is provided. Utility Model Content

It uses ultraviolet lamps to initially disinfect microorganisms, activated carbon granules to adsorb odors, spray components to deodorize through chemical reactions, gas guiding components to facilitate subsequent treatment, and a liquid level sensor and solenoid valve to achieve automatic liquid drainage. The device has a simple overall structure, reduces load and energy consumption, reduces investment costs, facilitates operation and maintenance, improves management efficiency, and overcomes the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-4 A biochemical tank odor treatment device includes a tank body 1, a top cover 2 at the top of the tank body 1, a first connecting pipe 11 connected to the middle of the top of the top of the top cover 2, a purification box 3 connected to one end of the first connecting pipe 11, a purification component inside the purification box 3, a first solenoid valve 4 installed on the top of one side of the purification component, a spray box 8 connected to one end of the first solenoid valve 4, a spray component at the top of the spray box 8, a support leg at the bottom of the purification box 3, a connecting rod welded between the purification box 3 and the spray box 8, and an air guiding component at the top of the spray box 8.

[0025] Ultraviolet lamps 10 are fixed on both sides of the inner wall of the top of the top cover 2, and a controller is fixed on one side of the upper surface of the top cover 2.

[0026] The top cover 2 has a protrusion in the middle, and the first connecting pipe 11 is connected to the middle of the protrusion, which facilitates the gas to gather in the inner side of the protrusion and facilitates the gas to be discharged from the first connecting pipe 11.

[0027] The purification component includes a support net 13 fixed to the inner wall of the purification box 3, and an activated carbon granule layer 14 is laid on the top of the support net 13.

[0028] The connection between the first solenoid valve 4 and the purification box 3 is located above the activated carbon granule layer 14, and the connection between the first connecting pipe 11 and the purification box 3 is located below the support net 13. A sealing cover 5 is provided at the top of the purification box 3.

[0029] The spray assembly includes a spray pipe 16 fixed to the top of the spray box 8, and spray heads 17 fixed at equal intervals on the spray pipe 16. One end of the spray head 17 extends to the outside of the spray box 8 and is connected to a second solenoid valve 15. One end of the second solenoid valve 15 is externally connected to the liquid outlet of the pump body.

[0030] A third solenoid valve 9 is installed at the bottom of the spray box 8, and a liquid level sensor 12 is fixed on the top of the inner wall of one side of the spray box 8. Both the third solenoid valve 9 and the liquid level sensor 12 are electrically connected to the controller.

[0031] Gas generated in pool 1 accumulates above pool 1. Irradiation by ultraviolet lamp 10 can disinfect some microorganisms. The gas enters purification box 3 along the first connecting pipe 11. The gas comes into contact with activated carbon granular layer 14, which adsorbs odors in the gas. Then the gas enters spray box 8. By opening the second solenoid valve 15 and the external pump, the pump delivers chemical detergent. The chemical detergent is sprayed out from spray head 17. The odor gas reacts with the chemical detergent. The chemical substances in the detergent neutralize, oxidize, and reduce the odor components, converting them into harmless or less harmful substances, thereby achieving the deodorization effect.

[0032] The liquid level sensor 12 detects the liquid level of the washing liquid collected in the spray box 8 and transmits the liquid level information to the controller. When the liquid level is too high, the controller controls the third solenoid valve 9 to open, so that the washing liquid can be discharged and collected by the external collection box.

[0033] Example 2 is an optimization based on Example 1, specifically:

[0034] The air guiding assembly includes an air collecting hood 6 that is rotatably mounted on the upper end of the spray box 8 via a hinge. The air collecting hood 6 can be fixedly connected to the spray box 8 using a lock. An air guiding pipe 7 is connected to the upper end of the air collecting hood 6.

[0035] Connecting the gas duct 7 to an external gas collection device allows for the collection of purified and deodorized gas, facilitating further purification.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
