Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, and relates to an integrated deodorization device, particularly an integrated deodorization device applied to drainage pumping stations. Background Technology

[0002] With the acceleration of urbanization, drainage pumping stations are playing an increasingly important role in treating urban sewage. However, the presence of odors such as hydrogen sulfide and ammonia in sewage during the operation of these pumping stations has long caused distress and inconvenience to the pumping station environment and the surrounding residents, becoming a problem that cannot be ignored. While drainage pumping stations are actively installing purification equipment, the limited applicability of existing deodorization and purification technologies due to the diverse types of odors produced by sewage means that some pumping stations still lack adequate deodorization facilities, resulting in odor emissions still exceeding standards. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an integrated deodorization device for drainage pumping stations. It solves the technical problem of poor odor purification performance in existing pumping stations.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An integrated deodorization device for drainage pumping stations includes a tower shell. The tower shell has a first chamber and a second chamber in a horizontal direction, and a connecting channel connects the first chamber and the second chamber. The first chamber has an odor inlet for odor input and is equipped with an odor scrubbing and purification device for spraying liquid to purify the odor. The second chamber is equipped with an ion generator for generating ions to react with the odor and deodorize it. The second chamber has a first gas outlet and a second gas outlet. A gas detection device is located near the first gas outlet in the second chamber. A chemical filter is connected to the second gas outlet for adsorbing residual odor.

[0006] This integrated deodorization equipment comprises three main odor removal devices: an odor scrubbing and purification unit, an ion generator, and a chemical filter media unit. The odor scrubbing and purification unit primarily uses sprayed liquid to adsorb odors or react with components in the odor to decompose them, thereby achieving a deodorizing effect. The ion generator mainly produces a large number of positive and negative ions by ionizing the air; these ions react with odor molecules to achieve a deodorizing effect. Finally, the chemical filter media unit mainly uses chemical materials to adsorb or catalyze components in the odor to achieve a deodorizing effect. This triple deodorization design works in concert to adsorb or catalyze multiple odors, thereby significantly improving the efficiency and effectiveness of odor purification.

[0007] The integrated deodorization device of this application is designed with an odor inlet in the first chamber. Odor is drawn from the pump station and enters the first chamber through the odor inlet for odor washing and purification. Then, it is connected to the second chamber for ion purification through a connecting channel. The second chamber is designed with two outlets, namely the first gas outlet and the second gas outlet. When the odor after ion purification meets the emission standards, the chemical filter device does not start, and the qualified gas is directly discharged from the first gas outlet. If the odor after ion purification still does not meet the standards, the chemical filter device starts to draw gas from the second chamber for further purification until the standards are met. The actual purification effect is used as feedback to determine whether chemical filter purification is to be carried out. This design ensures the purification effect while reducing the purification cost.

[0008] In the aforementioned integrated deodorization equipment for drainage pumping stations, the odor scrubbing and purification device includes a pipe, a high-pressure water pump, and a spray head. The bottom of the first chamber has an open liquid storage space at the top, where spray liquid is stored. One end of the pipe is connected to the liquid storage space, and the other end of the pipe is located near the top of the first chamber, where a spray head is installed. The high-pressure water pump is configured to be connected to the pipe to provide suction.

[0009] The first chamber of this application is designed with a liquid storage space at the bottom and an open top. Liquid is drawn from the liquid storage space and sprayed into the first chamber. When the odor components pass through the first chamber, the odor can be adsorbed. The sprayed liquid falls back into the liquid storage space under the action of gravity. This repeated cycle results in high purification efficiency and low purification cost.

[0010] In the above-mentioned integrated deodorization equipment for drainage pumping stations, the spray head is arranged opposite to the liquid storage space and facing the direction of the liquid storage space, and the spray head has a spray range of at least 90°.

[0011] The spray head of this application sprays directly towards the liquid storage space, which can accelerate the speed of liquid spraying and improve purification efficiency and effect by accelerating liquid circulation.

[0012] The spray head of this application has a spray range of more than 90°, which can cover the entire first chamber, thus enabling better contact and purification of odorous gases and further improving purification efficiency.

[0013] In the above-mentioned integrated deodorization equipment for drainage pumping stations, the connecting channel is located near the top wall of the first chamber and the second chamber, and a dehumidification device is provided at the top wall of the first chamber.

[0014] The channel connecting the first and second chambers in this application is located near the top. This design allows the odorous gas to come into more thorough contact with the sprayed liquid from bottom to top, resulting in better deodorization. Furthermore, the sprayed liquid is less likely to enter the channel and contaminate the second chamber. Additionally, a dehumidifier is installed at the connection point to effectively remove water mist from the airflow, preventing it from affecting the operation of the ion deodorization device in the second chamber.

[0015] In one of the above-mentioned integrated deodorization devices for drainage pumping stations, the dehumidification device includes a pull-out drawer, the bottom plate and side plate of the drawer are perforated, and disposable honeycomb dehumidification paper is placed inside the drawer.

[0016] The dehumidification device of this application achieves dehumidification by using disposable honeycomb dehumidification paper. This dehumidification method is low in cost, and the disposable honeycomb dehumidification paper can be replaced simply by pulling out the drawer, which is very convenient.

[0017] In the above-mentioned integrated deodorization equipment for drainage pumping stations, the odor inlet is located near the top of the liquid storage space, and a partition is fixed on the inner side of the first chamber above the odor inlet, with several small holes on the partition.

[0018] The odor inlet of this application is located near the liquid storage space, and the odor inlet is positioned low, so that the liquid sprayed down from above can come into more full contact with the odor for purification, resulting in a better purification effect.

[0019] A baffle is designed above the odor inlet. The sprayed liquid can contact the baffle to buffer and prolong the falling time. The liquid can overflow and drip down from the small holes in the baffle, while the odor needs to flow upward from the small holes in the baffle. This can greatly improve the contact efficiency and contact time between the liquid and the odor, allowing the two to react fully and thus improve the deodorization effect.

[0020] In the above-mentioned integrated deodorization equipment for drainage pumping stations, the partition is placed horizontally and has multiple layers, with adjacent partitions spaced apart.

[0021] The partitions in this application are placed horizontally and have a multi-layered structure, which further improves the deodorization efficiency.

[0022] In one of the above-mentioned integrated deodorization devices for drainage pumping stations, the second gas discharge port is connected to the chemical filter media device via an exhaust fan.

[0023] The second gas outlet of this application is connected to the chemical filter device via an exhaust fan. When the gas detected at the first gas outlet fails to meet the requirements, the exhaust fan is turned on to directly draw the second chamber into a negative pressure. The first gas outlet does not need to be closed. All the gas entering the second chamber is directly introduced into the chemical filter device for further deodorization and purification. This design is convenient to operate and has high purification efficiency.

[0024] In the above-mentioned integrated deodorization equipment for drainage pumping stations, the tower shell has a third chamber and a fourth chamber. The exhaust fan is located in the third chamber. The inlet of the exhaust fan is connected to a second gas discharge port through a duct. The outlet of the exhaust fan is connected to the fourth chamber through a duct. The chemical filter media device is located in the fourth chamber, and the fourth chamber has a third discharge port.

[0025] In one of the above-mentioned integrated deodorization devices for drainage pumping stations, the filter media in the chemical filter media device includes activated carbon particles.

[0026] The beneficial effects of this utility model are as follows: This integrated deodorization equipment includes an odor washing and purification device, an ion generating device, and a chemical filter media device. The odor washing and purification device sprays liquid to adsorb odors, the ion generating device ionizes air to generate a large number of positive and negative ions to decompose gases, and the chemical filter media device adsorbs or catalyzes odors through chemical materials. This triple deodorization device design is interconnected and can adsorb or catalyze multiple odors, thereby greatly improving the odor purification efficiency and effect.

Detailed Implementation

[0029] like Figure 1The illustrated integrated deodorization device for drainage pumping stations includes a tower shell 1. The tower shell 1 has a first chamber 11 and a second chamber 12 in the horizontal direction, and a connecting channel 15 connecting the first chamber 11 and the second chamber 12. The first chamber 11 has an odor inlet 16 for odor input, and an odor washing and purification device is installed in the first chamber 11. The odor washing and purification device is used to spray liquid to purify the odor in the first chamber 11. An ion generator 2 is installed in the second chamber 12. The ion generator 2 is a mature existing technology and will not be described in detail here. The ion generator 2 is used to generate ions to react with the odor to deodorize. The second chamber 12 has a first gas outlet 17 and a second gas outlet 18. A gas detection device, which is a toxic gas detector, is installed in the second chamber 12 near the first gas outlet 17. This is a mature existing technology and is usually purchased externally and will not be described in detail here. A chemical filter device 3 is connected to the second gas outlet 18 to adsorb residual odor. This integrated deodorization equipment comprises three main odor removal devices: an odor scrubbing and purification device, an ion generator 2, and a chemical filter media device 3. The odor scrubbing and purification device primarily uses sprayed liquid to adsorb odors or react with components in the odor to decompose them, thereby achieving a deodorizing effect. The ion generator 2 mainly generates a large number of positive and negative ions by ionizing the air. These ions react with odor molecules, thus achieving a deodorizing effect. Finally, the chemical filter media device 3 mainly uses chemical materials to adsorb or catalyze components in the odor to achieve a deodorizing effect. This triple deodorization device design works in concert to adsorb or catalyze multiple odors, thereby significantly improving the odor purification efficiency and effect. The integrated deodorization device of this application is designed with an odor inlet 16 in the first chamber 11. The odor is drawn from the pump station and enters the first chamber 11 through the odor inlet 16 for odor washing and purification. Then, it is connected to the second chamber 12 through the connecting channel 15 for ion purification. The second chamber 12 is designed with two outlets, namely the first gas outlet 17 and the second gas outlet 18. When the odor after ion purification meets the emission standard, the chemical filter device 3 does not start, and the qualified gas is directly discharged from the first gas outlet 17. When the odor after ion purification is still not qualified, the chemical filter device 3 starts to draw gas from the second chamber 12 for further purification until the standard is met. The actual purification effect is used as feedback to determine whether to carry out chemical filter purification. This design ensures the purification effect while reducing the purification cost.

[0030] Furthermore, the odor scrubbing and purification device includes a pipe 4, a high-pressure water pump 5, and a spray head 6. The bottom of the first chamber 11 has an open-topped liquid storage space 111, which stores spray liquid. One end of the pipe 4 leads into the liquid storage space 111, while the other end extends upwards to the outside and then laterally back into the upper part of the first chamber 11, with a spray head 6 installed at the end. The high-pressure water pump 5 is installed in the middle section of the external pipe 4. The high-pressure water pump is equipped with switch valves near the inlet and outlet, and flow and pressure gauges are also installed on the pipe 4. In this application, the bottom of the first chamber 11 is directly designed with a liquid storage space 111, which is open-topped. Liquid is drawn from the liquid storage space 111 and sprayed into the first chamber 11. When odor components pass through the first chamber 11, the odor is adsorbed. The sprayed liquid falls back into the liquid storage space 111 under gravity. This reciprocating cycle results in high purification efficiency and low purification cost.

[0031] Furthermore, the spray head 6 is positioned opposite to and facing the liquid storage space 111, and has a spray range of over 90°. The spray head 6 is a purchased component and will not be discussed further here. The spray head 6 of this application sprays directly towards the liquid storage space 111, which accelerates the liquid spraying speed and improves purification efficiency and effect by accelerating liquid circulation. The spray range of the spray head 6 of this application is greater than 90°, covering the entire first chamber 11, allowing for better contact and purification of odorous gases, further enhancing purification efficiency.

[0032] Furthermore, the connecting channel 15 is located near the top wall of the first chamber 11 and the second chamber 12, and a dehumidifying device 7 is installed on the top wall of the first chamber 11. Preferably, the dehumidifying device 7 includes a pull-out drawer with holes in the bottom and side panels, and disposable honeycomb dehumidifying paper is placed inside the drawer. The channel connecting the first chamber 11 and the second chamber 12 is located near the top, allowing for more thorough contact between the odorous gas and the sprayed liquid, resulting in better deodorization. Moreover, the sprayed liquid is less likely to enter the channel and contaminate the second chamber 12. The dehumidifying device 7 at the connecting channel 15 effectively removes water mist from the airflow, preventing interference with the operation of the ion deodorizing device in the second chamber 12. The dehumidifying device 7 uses disposable honeycomb dehumidifying paper for dehumidification, which is low-cost and conveniently replaceable by simply pulling out the drawer.

[0033] Furthermore, the odor inlet 16 is located near the top of the liquid storage space 111, and a baffle 8 is fixed inside the first chamber 11 above the odor inlet 16, with several small holes on the baffle 8. In this application, the odor inlet is located near the liquid storage space 111, and the odor inlet 16 is positioned relatively low. This allows the liquid sprayed from above to more fully contact and purify the odor, resulting in a better purification effect. The baffle 8 is designed above the odor inlet 16, allowing the sprayed liquid to contact the baffle 8, thus buffering and extending the descent time. The liquid can overflow and drip from the small holes on the baffle 8, while the odor needs to flow upwards through the small holes on the baffle 8. This effectively improves the contact efficiency and duration between the liquid and the odor, allowing them to fully react and thus enhancing the deodorization effect. The baffle 8 is horizontally placed and has multiple layers, with adjacent layers of baffle 8 spaced apart. The horizontally placed and multi-layered structure of the baffle 8 in this application further improves the deodorization efficiency.

[0034] Furthermore, the second gas discharge port 18 is connected to the chemical filter media device 3 via an exhaust fan 9. In this application, the second gas discharge port 18 and the chemical filter media device 3 are connected via an exhaust fan 9. When the gas detected at the first gas discharge port 17 fails to meet the requirements, the exhaust fan 9 is activated to directly create a negative pressure in the second chamber 12. The first gas discharge port 17 does not need to be closed, and all gas entering the second chamber 12 is directly introduced into the chemical filter media device 3 for further deodorization and purification. This design is convenient to operate and has high purification efficiency. The tower shell 1 has a third chamber 13 and a fourth chamber 14. The exhaust fan 9 is located in the third chamber 13. The inlet of the exhaust fan 9 is connected to the second gas discharge port 18 via a duct, and the outlet of the exhaust fan 9 is connected to the fourth chamber 14 via a duct. The chemical filter media device 3 is located in the fourth chamber 14, and the fourth chamber 14 has a third discharge port. The third discharge port is on the side of the tower shell and is not shown in the figure. The chemical filter media device 3 includes a frame located within the fourth chamber 14. The frame is ventilated and its surface is surrounded by a grid. Granular activated carbon is filled inside the frame. There are multiple such frames installed at intervals. Odors are introduced, adsorbed, filtered, and then discharged.
