Description

Technical Field

[0001] This utility model relates to the field of deodorization technology, and in particular to a modular, high-efficiency deodorization box that is easy to replace and maintain. Background Technology

[0002] During the wastewater treatment process, the wastewater contains a large amount of organic matter, such as proteins, carbohydrates, and oils. These organic substances are decomposed by microorganisms. Under anaerobic conditions, the decomposition of organic matter produces odorous substances such as methane and hydrogen sulfide. Under aerobic conditions, although the decomposition is relatively more thorough, it may still produce some volatile organic compounds (VOCs), such as alcohols, aldehydes, and ketones. These substances have a certain odor, therefore, deodorization boxes are needed during wastewater treatment to remove odors.

[0003] Chinese Patent No. 01920417761.5 discloses a biological deodorization system for a wastewater treatment plant, mainly comprising a horizontal deodorization tank, a centrifugal fan, an exhaust stack, and a PLC control system. The deodorization tank is divided into a pre-washing tank at the front and a biological filtration tank at the rear by a first partition and a second partition. The first partition is connected to the bottom of the deodorization tank but not to the top; the second partition is connected to the top of the deodorization tank but not to the bottom. An air passage is formed between the first and second partitions, located between the pre-washing tank and the biological filtration tank. An air inlet pipe is provided at the bottom of the side wall of the pre-washing tank, a first packing layer is provided in the middle of the pre-washing tank, and a first spray head is provided above the first packing layer. A second packing layer is provided in the middle of the biological filtration tank, and a second spray head is provided above the second packing layer.

[0004] The above-mentioned technical solution firstly affects the activity of bacteria when the ambient temperature is poor, as the temperature of the solution in the pool is low. This will affect the deodorization effect. At the same time, the biological deodorization effect will be reduced when the air is flowing rapidly, and the exhaust gas will still contain odor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a modular, high-efficiency deodorizing box that is easy to replace and maintain. It utilizes a sliding lifting plate structure combined with a positioning block structure that elastically engages with the positioning slot to achieve the function of fixing the lifting plate after adjustment. This solves the problem that when the power supply box is in a low-power state, it cannot supply power to the electric push rod, causing the rollers at the bottom of the power supply box to be unable to move downwards to support it.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular, high-efficiency deodorizing box that is easy to replace and maintain, comprising a deodorizing device; the deodorizing device consists of a biological deodorizing box, a first filter box, and a second filter box, which are installed side by side. The upper ends of the biological deodorizing box, the first filter box, and the second filter box are connected by a guide mechanism. The first filter box and the second filter box have the same structure. The first filter box has evenly spaced mounting grooves inside, and an activated carbon adsorption mechanism is installed inside the mounting grooves. An air outlet pipe is installed at the bottom of the first filter box. A water tank is installed at the bottom of the biological deodorizing box, and a heating mechanism is installed inside the water tank. Grilles are installed in the middle and upper parts of the biological deodorizing box, and biological packing material is placed on the upper part of the grilles. A spraying mechanism is installed above the biological packing material inside the biological deodorizing box. A circulation mechanism is installed on one side of the bottom of the biological deodorizing box, and the circulation mechanism connects the spraying mechanism and the water tank.

[0007] Furthermore, a packing sealing plate is installed on the outer side of the biological deodorization box corresponding to the upper position of the grid, and a drain pipe is installed at the bottom of the biological deodorization box corresponding to the water tank position, with a control valve installed on the upper side of the drain pipe.

[0008] Furthermore, the activated carbon adsorption mechanism consists of a mounting frame and an activated carbon adsorption plate, with the activated carbon adsorption plate installed inside the mounting frame and the mounting frame slidably installed inside the mounting groove.

[0009] Furthermore, the guiding mechanism consists of an air guide pipe and a three-way valve. The air guide pipe is installed in three directions of the three-way valve, and the end of the air guide pipe is installed at the upper end of the biological deodorization box, the first filter box, and the second filter box.

[0010] Furthermore, the spraying mechanism consists of a pipe network and spray heads. The spray heads are evenly installed at the bottom of the pipe network. The pipe network is installed inside the biological deodorization box at the position where the biological packing material is facing upwards. One end of the pipe network is installed on the upper side of the circulation mechanism.

[0011] Furthermore, the circulation mechanism consists of a circulation pump and a circulation pipe. The circulation pump is installed on one side of the bottom of the biological deodorization box. The front end of the circulation pump is connected to the water tank through the circulation pipe, and the upper end of the circulation pump is connected to the spraying mechanism through the circulation pipe.

[0012] Furthermore, the heating mechanism consists of an inlet pipe, an outlet pipe, and a heat exchange pipe. The inlet pipe and the outlet pipe are installed at both ends of the heat exchange pipe, which is installed inside the water tank.

[0013] Furthermore, the air intake mechanism consists of an air intake pipe, a one-way air intake valve, and a branch pipe. The branch pipe is installed on one side of the air intake pipe, one end of the air intake pipe extends out of the water tank, a one-way air intake valve is installed on the upper side of the air intake pipe, and air nozzles are evenly installed on the upper end of the branch pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The water in the lower water tank inside the biological deodorization box is kept at a suitable temperature by a heating mechanism to create a good environment for microorganisms. When the activated carbon adsorption mechanism in the first filter box needs to be replaced, the three-way valve of the guide mechanism will guide the gas to the second filter box, and vice versa, to ensure that the deodorization process is uninterrupted.

[0016] 2. The inlet pipe is used to introduce external hot water into the heat exchange tube. The hot water temperature is controlled at around 25 degrees Celsius. The hot water flows inside the heat exchange tube and exchanges heat with the water in the water tank through the tube wall. The water in the water tank absorbs heat and its temperature rises. The outlet pipe discharges the cooled water after heat exchange. By adjusting the water flow rate and hot water temperature of the inlet and outlet pipes, the water temperature in the water tank can be precisely controlled, providing a suitable temperature environment for the growth and metabolism of microorganisms in the biological deodorization box. Microorganisms are more active within a suitable temperature range and have a better degradation effect on odor pollutants. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-6As shown, this embodiment provides a modular, high-efficiency deodorizing box that is easy to replace and maintain, including a deodorizing device 1. The deodorizing device 1 consists of a biological deodorizing box 2, a first filter box 3, and a second filter box 4. The biological deodorizing box 2, the first filter box 3, and the second filter box 4 are installed side by side. The upper ends of the biological deodorizing box 2, the first filter box 3, and the second filter box 4 are connected by a guide mechanism 18. The first filter box 3 and the second filter box 4 have the same structure. The first filter box 3 has evenly installed installation grooves 33 inside, and an activated carbon adsorption mechanism 32 is installed inside the installation grooves 33. An air outlet pipe 5 is installed at the bottom of the first filter box 3. A water tank 31 is installed at the bottom of the biological deodorizing box 2. A heating mechanism 6 is installed inside the water tank 31. A grid 21 is installed in the middle and at the top of the biological deodorizing box 2. A biological filler 30 is placed on the top of the grid 21. A spraying mechanism 20 is installed above the biological filler 30 inside the biological deodorizing box 2. A circulation mechanism 7 is installed on one side of the bottom of the biological deodorizing box 2. The circulation mechanism 7 connects the spraying mechanism 20 and the water tank 31.

[0029] Preferably, a packing sealing plate 15 is installed on the outside of the biological deodorization box 2, corresponding to the upper position of the grid 21. A drain pipe 10 is installed at the bottom of the biological deodorization box 2, corresponding to the position of the water tank 31. A control valve 11 is installed on the upper side of the drain pipe 10. The packing sealing plate 15 facilitates the replacement of the biological packing 30 and allows for the direct addition of solution to the water tank 31. The drain pipe 10 is used to drain the water in the water tank 31 and can periodically clean impurities and metabolic products in the water tank 31. The control valve 11 is used to control the opening and closing of the drain pipe 10.

[0030] Preferably, the activated carbon adsorption mechanism 32 consists of a mounting frame 19 and an activated carbon adsorption plate 22. The activated carbon adsorption plate 22 is installed inside the mounting frame 19, and the mounting frame 19 is slidably installed inside the mounting groove 33. The mounting frame 19 serves to support and fix the activated carbon adsorption plate 22. It adopts a specific structural design and fits tightly with the activated carbon adsorption plate 22 to ensure that the activated carbon adsorption plate 22 remains stable during operation and will not be displaced or shaken due to factors such as airflow impact. At the same time, the mounting frame 19 is provided with air vents at both the upper and lower ends to prevent airflow from obstructing the passage of the activated carbon adsorption plate 22.

[0031] Preferably, the guiding mechanism 18 consists of an air guide pipe 17 and a three-way valve 16. The air guide pipe 17 is installed in three directions of the three-way valve 16. The end of the air guide pipe 17 is installed at the upper end of the biological deodorization box 2, the first filter box 3, and the second filter box 4. When the biological deodorization box 2 completes the degradation of odors and the purified air is delivered through the air guide pipe 17, the three-way valve 16 will make a precise judgment based on the current operating requirements of the system. If the activated carbon adsorption mechanism 32 in the first filter box 3 needs to be replaced, the three-way valve 16 will cleverly guide the gas to the second filter box 4; conversely, if the activated carbon adsorption mechanism 32 in the second filter box 4 needs to be replaced, the gas will be guided to the first filter box 3. Through this intelligent and flexible guiding operation, it is ensured that the entire air filtration process will not be interrupted during the replacement of the activated carbon adsorption mechanism 32, maintaining the continuous and stable operation of the deodorization device 1 and greatly improving the efficiency and reliability of the equipment.

[0032] Preferably, the spraying mechanism 20 consists of a pipe network 28 and spray heads 29. The spray heads 29 are evenly installed at the bottom of the pipe network 28. The pipe network 28 is installed inside the biological deodorization box 2, above the biological packing material 30. One end of the pipe network 28 is installed on the upper side of the circulation mechanism 7. The circulation mechanism 7 draws water from the water tank 31 into the pipe network 28. The pipe network 28 delivers the water to each spray head 29. When the water passes through the spray head 29, it is dispersed into fine water droplets and evenly sprayed onto the biological packing material 30 inside the biological deodorization box 2. On the one hand, the sprayed water can provide a moist living environment for the microorganisms on the biological packing material 30 and maintain their activity. On the other hand, the spraying water can wash away the metabolic products and other impurities produced on the surface of the biological packing material 30 by the microorganisms degrading pollutants, and promote the degradation of new odor pollutants by the microorganisms.

[0033] Preferably, the circulation mechanism 7 consists of a circulation pump 8 and a circulation pipe 9. The circulation pump 8 is installed at one side of the bottom of the biological deodorization box 2. The front end of the circulation pump 8 is connected to the water tank 31 through the circulation pipe 9, and the upper end of the circulation pump 8 is connected to the spray mechanism 20 through the circulation pipe 9. The circulation pump 8 provides power to make water flow in the circulation system. The front end of the circulation pump 8 draws water from the water tank 31 through the circulation pipe 9, pressurizes the drawn water, and delivers it to the spray mechanism 20, realizing the circulation process of water from the water tank 31 to the spray mechanism 20 and back to the water tank 31. This can ensure that the spray mechanism 20 has enough water to spray the biological filler 30, while also saving water resources and reducing operating costs.

[0034] Preferably, the heating mechanism 6 consists of an inlet pipe 23, an outlet pipe 24, and a heat exchange pipe 25. The inlet pipe 23 and the outlet pipe 24 are installed at both ends of the heat exchange pipe 25, which is installed inside the water tank 31. The inlet pipe 23 is used to introduce external hot water into the heat exchange pipe 25, and the hot water temperature is controlled at around 25 degrees Celsius. The hot water flows inside the heat exchange pipe 25 and exchanges heat with the water in the water tank 31 through the pipe wall of the heat exchange pipe 25. The water in the water tank 31 absorbs heat and its temperature rises. The outlet pipe 24 discharges the cooled water after heat exchange. By adjusting the water flow rate of the inlet pipe 23 and the outlet pipe 24, as well as the temperature of the hot water, the temperature of the water in the water tank 31 can be precisely controlled, providing a suitable temperature environment for the growth and metabolism of microorganisms in the biological deodorization box 2. This is because microorganisms are more active within a suitable temperature range and have a better degradation effect on odor pollutants.

[0035] Preferably, the air intake mechanism 14 consists of an air intake pipe 13, a one-way air intake valve 12, and a branch pipe 27. The branch pipe 27 is installed on one side of the air intake pipe 13. One end of the air intake pipe 13 extends out of the water tank 31. The one-way air intake valve 12 is installed on the upper side of the air intake pipe 13. Air nozzles 26 are evenly installed on the upper end of the branch pipe 27. The gas containing odor enters the system through the air intake pipe 13. The one-way air intake valve 12 prevents backflow of gas and ensures that the gas can only flow into the device along the air intake pipe 13. The branch pipe 27 diverts the gas in the air intake pipe 13. The gas is sprayed out through the air nozzles 26 at a certain pressure and angle, so that the gas can be evenly distributed in the water tank 31 and fully contact the water in the water tank 31. On the one hand, it can initially remove some water-soluble odor components, and on the other hand, it can also allow the gas to better enter the biological deodorization box 2 and contact the microorganisms on the biological packing 30, thereby improving the degradation efficiency of odor by microorganisms.

[0036] Work steps

[0037] The odorous gas first enters the deodorizing device 1 through the air intake mechanism 14. The odor-containing gas flows in through the air intake pipe 13, and the one-way air intake valve 12 prevents backflow. After being diverted by the branch pipe 27, the gas is sprayed out through the nozzle 26, evenly distributed within the water tank 31. During this process, some water-soluble odor components are initially removed. Next, the gas enters the biological deodorizing box 2. The water in the lower water tank 31 inside the biological deodorizing box 2 is maintained at a suitable temperature by the heating mechanism 6, creating a favorable environment for microorganisms. After passing through the lower grille 21, the gas comes into contact with the biological packing material 30, where the microorganisms degrade the odorous pollutants. The spray mechanism 20 then sprays the water in the water tank 31... Water is drawn into the pipeline 28 through the circulation mechanism 7 and sprayed onto the biological packing material 30 by the spray head 29. This maintains the activity of microorganisms and washes away metabolic products. The degraded gas passes through the upper grille 21 and enters the first filter box 3 or the second filter box 4 through the guide mechanism 18. In the first filter box 3 or the second filter box 4, the gas is further adsorbed and purified by the activated carbon adsorption mechanism 32 in the installation groove 33. Finally, the clean gas is discharged through the gas outlet pipe 5. When it is necessary to replace the activated carbon adsorption mechanism 32 in the first filter box 3, the three-way valve 16 of the guide mechanism 18 guides the gas to the second filter box 4, and vice versa, to ensure that the deodorization process is uninterrupted.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
