Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an enhanced deodorization device that combines activated carbon with ions. Background Technology

[0002] Activated carbon and ion deodorization devices are widely used in municipal applications such as wastewater pumping stations, regulating tanks, and wastewater treatment plants for treating exhaust gases. These gases often contain harmful substances like hydrogen sulfide, ammonia, and volatile organic compounds (VOCs), which not only have strong, pungent odors and seriously impact the surrounding environment and residents' lives, causing air pollution and unpleasant odors, but also pose threats to human health, such as respiratory irritation and poisoning. Furthermore, direct discharge of untreated exhaust gases can corrode facilities in wastewater pumping stations, regulating tanks, and wastewater treatment plants, shortening their lifespan and increasing maintenance costs. Therefore, effectively treating these exhaust gases using professional waste gas treatment technologies and equipment is a necessary measure to protect the environment, safeguard public health, and maintain the normal operation of facilities.

[0003] In existing technologies, activated carbon adsorption equipment or ion purification equipment is generally used to treat medium- and low-concentration waste gases generated by sewage pumping stations, regulating tanks, and sewage treatment plants. Conventional activated carbon adsorption equipment is suitable for low-concentration waste gas conditions, but its ability to cope with fluctuations in air volume and odor concentration is weak. To improve the treatment effect, it is generally used in series with other processes. Furthermore, in actual use, activated carbon adsorption equipment lacks measures to dehumidify the waste gas, causing moisture in the waste gas to compete with pollutant molecules for adsorption on the surface of activated carbon. When the humidity of the waste gas is too high, the adsorption capacity of activated carbon for pollutants such as hydrogen sulfide and VOCs will decrease significantly. At the same time, high humidity may also cause activated carbon particles to expand and clump, shortening their service life and increasing equipment maintenance costs.

[0004] While traditional ion purification equipment can be used immediately, has a certain ability to treat various pollutants, and is relatively good at coping with fluctuations in air volume and odor concentration, it needs to be powered on continuously. Long-term use will significantly increase operating costs. At the same time, the ion tubes work continuously under a high-voltage electric field, which can easily shorten their service life due to oxidation, dust accumulation, and other problems. Utility Model Content

[0005] The main objective of this invention is to provide an enhanced deodorization device that combines activated carbon with ions, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An enhanced deodorization device combining activated carbon and ions includes an activated carbon adsorption box and an ion deodorization device. The activated carbon adsorption box and the ion deodorization device are fixedly connected together by a detection duct. A dehumidification mechanism is also provided on the left side of the activated carbon adsorption box. The dehumidification mechanism includes a dehumidification pipe, an electric heating fan, a three-way pipe, a heating regeneration box, an electric actuator, and a silica gel dehumidification screen. The dehumidification pipe is fixedly connected to the left side of the activated carbon adsorption box, and heating regeneration boxes are fixedly connected to both sides of the dehumidification pipe. The three-way pipe is fixedly connected to the front end of the electric heating fan, and a conveying pipe is connected between the three-way pipe and the air inlet hood at the front end of the heating regeneration box. An electric actuator is also fixedly connected to the side wall of the heating regeneration box, and a silica gel dehumidification screen is fixedly connected to the output end of the electric actuator.

[0008] As a preferred embodiment of this utility model, the activated carbon adsorption box is filled with activated carbon filler, the ion deodorization device is fixedly installed with an ion generator, a gas detector is fixedly installed on the front wall of the detection duct, and the sensing end of the gas detector is located in the detection duct. The two ends of the detection duct are fixedly installed together with the exhaust end on the right side of the activated carbon adsorption box and the air inlet end on the left side of the ion deodorization device, respectively.

[0009] As a preferred embodiment of this utility model, the dehumidification pipe is fixedly installed on the air inlet end on the left side of the activated carbon adsorption box, and heating regeneration boxes are fixedly installed on the left and right side walls of the dehumidification pipe respectively. An air inlet hood is fixedly installed on the front wall of the heating regeneration box, and vertical openings communicating with the heating regeneration box are respectively opened on the left and right side walls of the dehumidification pipe. Guide strips extending into the heating regeneration box are also fixedly installed on the bottom and top surfaces of the dehumidification pipe respectively.

[0010] As a preferred embodiment of this utility model, a set of symmetrical moisture sensors are fixedly installed on the top surface of the dehumidification tube, and the output ends of the moisture sensors are respectively fixedly installed inside the silicone dehumidification mesh.

[0011] As a preferred technical solution of this utility model, an electric push rod is fixedly installed on the outer wall of the heating regeneration box, and a silicone dehumidifying screen is fixedly installed on the output end of the electric push rod. The top and bottom surfaces of the silicone dehumidifying screen are respectively provided with guide grooves corresponding to the guide strips.

[0012] As a preferred embodiment of this utility model, a three-way pipe is fixedly installed on the output end of the electric heating fan, and valves are fixedly installed on the two output ends of the three-way pipe respectively. The valves and the air inlet hood are fixedly connected to a conveying pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, on the one hand, activated carbon adsorption equipment is combined with ion equipment. When the gas detector detects that the gas treated by the activated carbon adsorption box reaches the limit concentration value, the ion generator can be turned off to save electricity. When the gas detector detects that the concentration of the emitted gas exceeds the standard, the ion generator is turned on. The two devices run simultaneously to enhance the removal rate and ensure that the treated gas meets the emission standards. On the other hand, a dehumidification mechanism is set up to remove moisture from the waste gas using a silica gel dehumidification screen. This avoids moisture and pollutants competing for adsorption on the activated carbon surface, ensuring the adsorption capacity of the activated carbon, extending its service life, and reducing maintenance costs. At the same time, the silica gel dehumidification screen is regenerated through an electric heating fan and a heated regeneration box. The ion generator and activated carbon adsorption work together to reduce the continuous high-pressure operation time of the ion tube, reduce operating costs, and extend the service life of the ion tube. This effectively solves the problems of weak ability of activated carbon adsorption equipment to cope with air volume and odor concentration fluctuations, lack of dehumidification measures, high operating costs of ion purification equipment, and easy shortening of the life of ion tubes in the existing technology. It provides an efficient and economical solution for the treatment of gases collected in sewage pumping stations, regulating tanks, and sewage treatment plants, effectively protecting the environment, ensuring the health of residents, and maintaining the normal operation of facilities.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] like Figure 1 - Figure 5 As shown, an enhanced deodorization device combining activated carbon and ions includes an activated carbon adsorption box 1 and an ion deodorization device 2. The activated carbon adsorption box 1 and the ion deodorization device 2 are fixedly connected together by a detection air duct 3. A dehumidification mechanism 7 is also provided on the left side of the activated carbon adsorption box 1. The dehumidification mechanism 7 includes a dehumidification pipe 8, an electric heating fan 9, a three-way pipe 10, a heating regeneration box 13, an electric push rod 18, and a silica gel dehumidification screen 19. The dehumidification pipe 8 is fixedly connected to the left side of the activated carbon adsorption box 1, and the heating regeneration box 13 is fixedly connected to both sides of the dehumidification pipe 8. The three-way pipe 10 is fixedly connected to the front end of the electric heating fan 9, and a conveying pipe 12 is connected between the three-way pipe 10 and the air inlet hood 14 at the front end of the heating regeneration box 13. An electric push rod 18 is also fixedly connected to the side wall of the heating regeneration box 13, and a silica gel dehumidification screen 19 is fixedly connected to the output end of the electric push rod 18.

[0023] like Figure 1 and Figure 2 As shown, the activated carbon adsorption box 1 is filled with activated carbon packing 4. Activated carbon is a type of very fine carbon particle with a large surface area. The carbon particles also contain even finer capillaries, which have a strong adsorption capacity. Activated carbon adsorption is a treatment method that introduces gas into an adsorption tower filled with activated carbon to adsorb harmful components in the gas. The ion deodorization device 2 has an ion generator 5 fixedly installed inside. Under the action of a high-voltage electric field, the ion generator 5 produces a large number of positive and negative oxygen ions, which have strong oxidizing properties. It can oxidize and decompose pollutants such as methanethiol, ammonia, hydrogen sulfide, ethers, and amines in a very short time, ultimately producing stable and non-toxic substances such as carbon dioxide and water. The gas detector 6 is fixedly installed on the front wall of the detection duct 3, and the sensing end of the gas detector 6 is located in the detection duct 3. The gas detector 6 detects whether the gas after being filtered by the activated carbon adsorption box 1 meets the emission standards. If it meets the standards, there is no need to turn on the ion generator 5, saving electricity. If it does not meet the standards, the ion generator 5 is turned on for further treatment to ensure that the exhaust gas can be effectively treated. The two ends of the detection duct 3 are fixedly installed together with the exhaust end on the right side of the activated carbon adsorption box 1 and the air inlet end on the left side of the ion deodorization device 2, respectively. The detection duct 3 is used to connect the activated carbon adsorption box 1 and the ion deodorization device 2.

[0024] like Figures 3-5As shown, the dehumidification pipe 8 is fixedly installed on the air inlet end on the left side of the activated carbon adsorption box 1, and heating regeneration boxes 13 are fixedly installed on the left and right side walls of the dehumidification pipe 8, respectively. An air inlet hood 14 is fixedly installed on the front wall of the heating regeneration box 13, and hot air can enter the heating regeneration box 13 through the air inlet hood 14. Vertical openings 15 communicating with the heating regeneration box 13 are opened on the left and right side walls of the dehumidification pipe 8, respectively. Guide strips 16 extending into the heating regeneration box 13 are also fixedly installed on the bottom and top surfaces of the dehumidification pipe 8, respectively, to ensure that the silica gel dehumidification mesh 19 that needs to be regenerated can enter the corresponding heating regeneration box 13 for processing through the vertical openings 15 along the guide strips 16.

[0025] like Figures 3-5 As shown, a set of symmetrical moisture sensors 17 are fixedly installed on the top surface of the dehumidification pipe 8, and the output ends of the moisture sensors 17 are respectively fixedly installed inside the silicone dehumidification mesh 19. The moisture sensors 17 are used to detect whether the silicone dehumidification mesh 19 has reached saturation after dehumidification.

[0026] like Figures 3-5 As shown, an electric push rod 18 is fixedly installed on the outer wall of the heating regeneration box 13, and a silica gel dehumidifying screen 19 is fixedly installed on the output end of the electric push rod 18. The top and bottom surfaces of the silica gel dehumidifying screen 19 are respectively provided with guide grooves 20 corresponding to the guide bars 16. If the silica gel dehumidifying screen 19 currently located in the dehumidification pipe 8 reaches saturation after dehumidifying the exhaust gas and being detected by the moisture sensor 17, the electric push rod 18 can be activated to pull the silica gel dehumidifying screen 19 so that the silica gel dehumidifying screen 19 passes through the guide grooves 20 and enters the corresponding heating regeneration box 13 along the guide bars 16 for heating regeneration treatment. At the same time, the electric push rod 18 on the opposite side will push the silica gel dehumidifying screen 19 in the heating regeneration box 13 into the dehumidification pipe 8 to ensure the continuous dehumidification treatment of the exhaust gas, so as to ensure the adsorption effect and service life of the activated carbon filler 4 on the exhaust gas.

[0027] like Figures 3-5 As shown, a three-way pipe 10 is fixedly installed on the output end of the electric heating fan 9, and valves 11 are fixedly installed on the two output ends of the three-way pipe 10 respectively. A conveying pipe 12 is fixedly installed between the valves 11 and the air inlet hood 14. When the valve 11 at the corresponding end of the three-way pipe 10 is opened, the electric heating fan 9 will convey hot air from the air inlet hood 14 to the heating regeneration box 13 through the conveying pipe 12 to purge the saturated silica gel desiccant mesh 19. The heated gas flows through the adsorbent bed of the silica gel desiccant mesh 19, transfers heat and dries and removes moisture.

[0028] The activated carbon and ion-binding enhanced deodorization device and dehumidification mechanism 7 work on the following principle:

[0029] The exhaust gas first enters the dehumidification pipe 8 of the dehumidification unit 7. A silica gel dehumidification mesh 19 is pre-arranged inside the dehumidification pipe 8. The silica gel dehumidification mesh 19 uses its high adsorption capacity to adsorb and remove moisture from the exhaust gas, avoiding competition between moisture and pollutants on the surface of the activated carbon packing 4 in the subsequent activated carbon adsorption box 1, ensuring the adsorption capacity of the activated carbon and extending its service life. During the dehumidification process, the moisture sensor 17 installed on the top surface of the dehumidification pipe 8 monitors the moisture absorption status of the silica gel dehumidification mesh 19 in real time. When the silica gel dehumidification mesh 19 in the dehumidification pipe 8 is detected to be saturated, the electric push rod 18 installed on the outer wall of the heating regeneration box 13 on the corresponding side is activated, pulling the silica gel dehumidification mesh 19 through the guide groove 20 and along the guide bar 16 from the vertical opening 15 on the corresponding side wall of the dehumidification pipe 8 into the heating regeneration box 13. At the same time, the electric push rod 18 on the opposite side pushes the silica gel dehumidification mesh 19 that has been regenerated in the heating regeneration box 13 into the dehumidification pipe 8 to continue the dehumidification operation, ensuring that the dehumidification process is continuous and uninterrupted.

[0030] The silica gel desiccant mesh 19 enters the heating and regeneration chamber 13 and begins the regeneration process. At this time, the electric heating fan 9 and the valve 11 on the corresponding three-way pipe 10 on one side of the heating and regeneration chamber 13 are turned on. The hot air generated by the electric heating fan 9 enters the heating and regeneration chamber 13 from the air inlet hood 14 through the three-way pipe 10 and the delivery pipe 12. The hot air flows through the adsorbent bed of the silica gel desiccant mesh 19, transfers heat and dries and removes moisture, so that the silica gel desiccant mesh 19 restores its moisture absorption capacity for the next use. After the moisture sensor 17 detects that the moisture content is lower than the preset value, the electric heating fan 9 and the valve 11 are turned off.

[0031] After dehumidification, the waste gas enters the activated carbon adsorption box 1. The activated carbon packing 4 inside the box uses its huge surface area and capillary structure to adsorb harmful substances such as hydrogen sulfide, ammonia, and volatile organic compounds (VOCs) in the waste gas, further purifying the waste gas.

[0032] The purified exhaust gas then enters the detection duct 3. The gas detector 6 installed at the front end of the detection duct 3 monitors the exhaust gas in real time. If the gas detector 6 detects that the exhaust gas concentration meets the emission standards, the exhaust gas can be discharged directly without the need to turn on the ion generator 5 for purification. If the exhaust gas concentration exceeds the standard, the ion generator 5 in the ion deodorization device 2 is activated. Under the action of a high-voltage electric field, a large number of positive and negative oxygen ions are generated. These ions have strong oxidizing properties and can oxidize and decompose the remaining polluting odor factors in the exhaust gas, such as methanethiol, ethers, and amines, in a very short time, ultimately generating stable and harmless small molecules such as carbon dioxide and water. The simultaneous operation of the two devices enhances the removal rate and ensures that the treated gas meets the emission standards.

[0033] This achieves an organic combination of activated carbon adsorption and ion purification, which not only improves the waste gas treatment effect but also reduces operating costs and extends the service life of the equipment, providing an efficient and economical solution for the treatment of gases collected in sewage pumping stations, regulating tanks, and sewage treatment plants.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
