Description

Technical Field

[0001] This utility model relates to the field of odor gas treatment technology, and in particular to a multi-stage biological deodorization integrated device for odor gases. Background Technology

[0002] With the rapid development of industrial production, wastewater treatment, and waste disposal, the emission of odorous gases is increasing, seriously impacting the environment and people's lives. Odorous gases not only harm the human respiratory and nervous systems but also affect the surrounding ecological environment. Traditional methods for treating odorous gases, such as physical methods (adsorption, absorption, etc.) and chemical methods (combustion, oxidation, etc.), can remove odorous gases to some extent, but they suffer from high treatment costs and secondary pollution. Biological deodorization, as a green and environmentally friendly treatment method, is gradually gaining widespread attention due to its advantages such as good treatment effect, low operating cost, and no secondary pollution.

[0003] However, biological deodorization devices in related technologies often suffer from low processing efficiency, making it inconvenient to control the amount and flow rate of odorous gases according to deodorization needs. They are prone to problems such as excessively fast flow rates reducing deodorization effects and excessively slow flow rates reducing deodorization efficiency, making it difficult to meet the needs of actual production and daily life. Therefore, we propose a multi-stage biological deodorization integrated device for odorous gases to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing a multi-stage biological deodorization integrated device for malodorous gases.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-stage biological deodorization integrated device for malodorous gases includes a deodorization box containing three deodorization chambers. A passage is provided between two adjacent deodorization chambers. From left to right, the three deodorization chambers are arranged with a pretreatment unit, a multi-stage biological treatment unit, and a post-treatment unit. An air inlet pipe is fixedly connected to one side of the deodorization box, and a flow regulating mechanism is provided on the air inlet pipe. An air outlet pipe is fixedly connected to the other side of the deodorization box, and a controller is fixedly connected to one side of the deodorization box.

[0007] As a preferred embodiment of this utility model, the pretreatment unit includes a left perforated plate fixedly disposed in the deodorization chamber on the left side. The top of the left perforated plate is filled with filler, and three left spray pipes are fixedly connected to the inner walls of the front and rear sides of the deodorization chamber on the left side. Multiple left spray nozzles are fixedly connected to the bottom of the left spray pipes.

[0008] As a preferred embodiment of this utility model, the multi-stage biological treatment unit includes three right-side perforated plates fixedly connected to the middle deodorization chamber. Different biological fillers are placed on the top of each of the three right-side perforated plates. Three right-side spray pipes are fixedly connected to the front and rear inner walls of the middle deodorization chamber, and multiple right-side nozzles are fixedly connected to the bottom of each right-side spray pipe.

[0009] As a preferred embodiment of this utility model, the post-treatment unit includes an activated carbon mesh and a demister fixedly connected to the deodorization chamber on the right side. The demister is located above the activated carbon mesh, and a water outlet pipe is fixedly connected to one side of the bottom of the demister.

[0010] As a preferred embodiment of this invention, a placement seat is fixedly connected to the other side of the deodorizing box, and a water tank is movably placed inside the placement seat, with the water tank located directly below the water outlet pipe.

[0011] As a preferred embodiment of this invention, drain pipes are fixedly connected to the front inner walls of the three deodorization chambers.

[0012] In a preferred embodiment of this utility model, the flow regulating mechanism includes a flow meter mounted on the intake pipe, a gate plate rotatably connected to the inner walls of the front and rear sides of the intake pipe, and a slide rail fixedly connected to the top of the intake pipe. A drive motor is fixedly connected to the top of the slide rail, and a lifting screw is fixedly connected to the output shaft of the drive motor. A slider is threaded onto the outer side of the lifting screw, and a support plate is fixedly connected to the bottom of the slider. A moving rod is fixedly connected to the bottom of the support plate, and a mounting plate is fixedly connected to the bottom of the moving rod. A cylinder is fixedly mounted inside the mounting plate, and two frames are slidably mounted on the outer side of the cylinder. Both frames are fixedly connected to one side of the gate plate, and limit plates are fixedly connected to the front and rear ends of the cylinder. The two limit plates movably abut against the outer side of the corresponding frames.

[0013] As a preferred embodiment of this utility model, an upper sealing gasket is fixedly connected to the top of the gate, the upper sealing gasket is movably abutting against the top inner wall of the air intake pipe, and a lower sealing gasket is fixedly connected to the bottom of the gate.

[0014] In this invention, a multi-stage biological deodorization integrated device for malodorous gases is described. The malodorous gas first enters the pre-left deodorization chamber under the control of the flow regulation mechanism in the inlet pipe. The left nozzle and left spray nozzle spray absorbent liquid. Under the action of the packing, the malodorous gas comes into full contact with the sprayed absorbent liquid, and the particulate matter and water-soluble pollutants are captured by the absorbent liquid. At the same time, the temperature and humidity of the gas are regulated. The pretreated gas enters the middle deodorization chamber through the left channel. It passes through three different biological packing materials in the multi-stage biological treatment unit, such as activated carbon, volcanic rock, and ceramsite. A large number of microorganisms are attached to the surface of the biological packing materials. The microorganisms use the organic pollutants in the malodorous gas as carbon source and energy source to grow and reproduce. Through biodegradation, they are converted into harmless substances. The treated gas enters the right deodorization chamber. After passing through the activated carbon mesh in the post-treatment unit, it can again adsorb residual pollutants and odors. The demister removes water mist, and the water is discharged into the water tank through the outlet pipe for collection and treatment. The treated gas that meets the standards is discharged from the outlet pipe.

[0015] In this invention, a multi-stage biological deodorization integrated device for malodorous gases is described. When the air intake flow needs to be adjusted, the controller starts the drive motor, which drives the rotation of the lifting screw. The lifting screw drives the slider, support plate, moving rod, mounting plate, and cylinder to rise and fall. The cylinder slides within the two frames, causing the gate to deflect upward or downward, thereby adjusting the effective cross-sectional area of ​​the air intake and thus the flow rate. The flow rate can be measured by a flow meter. When the requirement is met, the flow meter sends a signal to the controller, which shuts off the drive motor. This allows for precise control of the air intake flow rate of malodorous gases, avoiding excessively fast flow rates that reduce the deodorization effect and excessively slow flow rates that reduce deodorization efficiency, thus ensuring both the deodorization effect and efficiency.

[0016] This utility model has a reasonable structural design. Through the synergistic effect of the pretreatment unit, multi-stage biological treatment unit and post-treatment unit, it can comprehensively and deeply treat odorous gases, improve the removal efficiency of odorous gases, and has a good treatment effect on various types of odorous gases. Moreover, the air inlet flow rate can be adjusted to avoid the deodorization effect being reduced due to excessively fast flow rate, and the deodorization efficiency being reduced due to excessively slow flow rate, thereby ensuring the deodorization effect and efficiency.

[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] Reference Figures 1-5 A multi-stage biological deodorization integrated device for malodorous gases includes a deodorization box 1, which contains three deodorization chambers 10. A passage 11 is provided between two adjacent deodorization chambers 10. From left to right, the three deodorization chambers 10 are arranged with a pretreatment unit 3, a multi-stage biological treatment unit 4, and a post-treatment unit 5. An air inlet pipe 9 is fixedly connected to one side of the deodorization box 1, and a flow regulating mechanism 6 is provided on the air inlet pipe 9. An air outlet pipe 8 is fixedly connected to the other side of the deodorization box 1. A controller 7 is fixedly connected to one side of the deodorization box 1.

[0025] Furthermore, refer to Figures 1-3The pretreatment unit 3 includes a left perforated plate 34 fixedly installed in the deodorization chamber 10 on the left side. The top of the left perforated plate 34 is filled with filler 33. Three left spray pipes 31 are fixedly connected to the inner walls of the front and rear sides of the deodorization chamber 10 on the left side. Multiple left nozzles 32 are fixedly connected to the bottom of the left spray pipes 31. The multi-stage biological treatment unit 4 includes three right perforated plates 43 fixedly connected in the deodorization chamber 10 in the middle. Different biological filler 44 is placed on the top of each of the three right perforated plates 43. Three right spray pipes 41 are fixedly connected to the inner walls of the front and rear sides of the deodorization chamber 10 in the middle. Multiple right nozzles 42 are fixedly connected to the bottom of the right spray pipes 41. The posttreatment unit 5 includes an activated carbon mesh 54 and a demister 55 fixedly connected in the deodorization chamber 10 on the right side. The demister 55 is located above the activated carbon mesh 54. A water outlet pipe 51 is fixedly connected to the bottom of one side of the demister 55.

[0026] Using the above scheme: The malodorous gas first enters the pre-left deodorization chamber 10 under the control of the flow regulation mechanism in the inlet pipe 9. The left nozzle 31 and left spray head 32 spray absorbent liquid. Under the action of the packing material 33, the malodorous gas comes into full contact with the sprayed absorbent liquid, and particulate matter and water-soluble pollutants are captured by the absorbent liquid. Simultaneously, the temperature and humidity of the gas are regulated. The pretreated gas enters the middle deodorization chamber 10 through the left channel 11, passing through three different biological packing materials 44 in the multi-stage biological treatment unit 4, such as activated carbon, volcanic rock, and ceramsite. The surface of the biological packing material 44 is covered with a large number of microorganisms. These microorganisms use the organic pollutants in the malodorous gas as a carbon source and energy source for growth and reproduction, converting them into harmless substances through biodegradation. The treated gas enters the right deodorization chamber 10, passing through the activated carbon mesh 54 in the post-treatment unit 5, where residual pollutants and odors are adsorbed again. The demister 55 removes water mist, and the water is discharged through the outlet pipe 51 into the water tank 52 for collection and treatment. The treated gas that meets the standards is discharged through the outlet pipe 8.

[0027] Furthermore, a placement seat 53 is fixedly connected to the other side of the deodorizing box 1, and a water tank 52 is movably placed inside the placement seat 53. The water tank 52 is located directly below the water outlet pipe 51, which facilitates the collection and treatment of the discharged water.

[0028] Furthermore, drain pipes 2 are fixedly connected to the front inner walls of the three deodorization chambers 10 to facilitate the discharge of wastewater.

[0029] Furthermore, refer to Figures 2-5The flow regulating mechanism 6 includes a flow meter 601 mounted on the intake pipe 9, a gate 602 rotatably connected to the inner walls of the front and rear sides of the intake pipe 9, and a slide rail 605 fixedly connected to the top of the intake pipe 9. A drive motor 606 is fixedly connected to the top of the slide rail 605. A lifting screw 607 is fixedly connected to the output shaft of the drive motor 606. A slider 608 is threaded on the outer side of the lifting screw 607. A support plate 609 is fixedly connected to the bottom of the slider 608. A moving rod 610 is fixedly connected to the bottom of the support plate 609. A mounting plate 611 is fixedly connected to the bottom of the moving rod 610. A cylinder 612 is fixedly mounted inside the mounting plate 611. Two frames 613 are slidably mounted on the outer side of the cylinder 612. Both frames 613 are fixedly connected to one side of the gate 602. Limiting discs 614 are fixedly connected to the front and rear ends of the cylinder 612. The two limiting discs 614 are respectively movably abutting against the outer side of the corresponding frame 613.

[0030] The above scheme works as follows: When the intake airflow needs to be adjusted, the controller 7 starts the drive motor 606, which drives the rotation of the lifting screw 607. The lifting screw 607 drives the slider 608, support plate 609, moving rod 610, mounting plate 611, and cylinder 612 to rise and fall. The cylinder 612 slides within the two frames 613, causing the gate 602 to deflect upwards or downwards, thereby adjusting the effective intake cross-sectional area and thus the flow rate. The flow rate can be measured by the flow meter 601. When the requirement is met, the flow meter 601 sends a signal to the controller 7, and the controller 7 shuts off the drive motor 606. This allows for precise control of the intake airflow of odorous gases, avoiding excessively fast flow rates that reduce the deodorization effect, and excessively slow flow rates that reduce deodorization efficiency, thus ensuring both the deodorization effect and efficiency.

[0031] Furthermore, an upper sealing gasket 603 is fixedly connected to the top of the gate 602, and the upper sealing gasket 603 movably abuts against the top inner wall of the air intake pipe 9. A lower sealing gasket 604 is fixedly connected to the bottom of the gate 602 to facilitate the sealing of the connection.

[0032] In this invention, the malodorous gas first enters the pre-left deodorization chamber 10 under the control of the flow regulation mechanism in the inlet pipe 9. The left nozzle 31 and left spray head 32 spray absorbent liquid. Under the action of the packing material 33, the malodorous gas comes into full contact with the sprayed absorbent liquid, and particulate matter and water-soluble pollutants are captured by the absorbent liquid. Simultaneously, the temperature and humidity of the gas are regulated. The pretreated gas then enters the middle deodorization chamber 10 through the left channel 11, passing through three different biological packing materials 44 in the multi-stage biological treatment unit 4, such as activated carbon... The surface of the biological filler 44, which contains materials such as charcoal, volcanic rock, and ceramsite, is covered with a large number of microorganisms. These microorganisms use organic pollutants in the malodorous gas as a carbon source and energy source to grow and reproduce, and transform them into harmless substances through biodegradation. The treated gas enters the deodorization chamber 10 on the right and passes through the activated carbon mesh 54 in the post-treatment unit 5, where it can adsorb residual pollutants and odors again. The demister 55 removes water mist, and the water is discharged into the water tank 52 through the water outlet pipe 51 for collection and treatment. The treated gas that meets the standards is discharged through the gas outlet pipe 8.

[0033] When the intake airflow needs to be adjusted, the controller 7 starts the drive motor 606, which drives the rotation of the lifting screw 607. The lifting screw 607 drives the slider 608, support plate 609, moving rod 610, mounting plate 611 and cylinder 612 to rise and fall. The cylinder 612 slides within the two frames 613 and drives the gate 602 to deflect upward or downward, thereby adjusting the effective intake cross-sectional area and thus the flow rate. The flow rate can be measured by the flow meter 601. When the requirement is met, the flow meter 601 sends a signal to the controller 7, and the controller 7 shuts off the drive motor 606. This allows for precise control of the intake airflow of odorous gases, avoiding excessively fast flow rates that reduce the deodorization effect and excessively slow flow rates that reduce deodorization efficiency, thus ensuring both the deodorization effect and efficiency.
