Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption and desorption, specifically to an activated carbon adsorption and desorption waste gas treatment device. Background Technology

[0002] Activated carbon is an adsorption material widely used in water treatment, air purification, desulfurization, and denitrification. Its adsorption principle is mainly due to the well-developed pore structure and high specific surface area of ​​activated carbon, which can effectively adsorb and remove various organic and inorganic substances. When activated carbon is saturated, it needs to be desorbed to restore its adsorption performance. Activated carbon adsorption and desorption can also be applied to waste gas treatment devices. Common methods for treating waste gas in waste gas treatment devices include adsorption, absorption, catalytic combustion, and thermal combustion. When selecting a purification method, priority should be given to methods that are low in cost, low in energy consumption, and do not cause secondary pollution, so as to turn harm into benefit and fully recover and utilize components and waste heat.

[0003] A search revealed a waste gas treatment device based on activated carbon adsorption-desorption, disclosed in publication number CN215085957U. This device includes a housing and a cover, which are fixedly connected by screws. A partition is fixedly connected to the inner wall of the housing. An inlet pipe and an outlet pipe, communicating with each other, are fixedly connected to the left and right sides of the housing, corresponding to the top of the partition. Two fixed sleeves are symmetrically arranged at the bottom of the inner wall of the housing, and a rotating block is movably connected within each fixed sleeve. This waste gas treatment device based on activated carbon adsorption-desorption has a reasonable structural design and is easy to use. It employs a rotating first activated carbon adsorption pad, ensuring that all contact surfaces of the pad can contact the waste gas, thereby improving purification efficiency and service life. The second activated carbon adsorption pad further enhances the purification effect. Furthermore, after long-term use, the expired activated carbon adsorption pad can be quickly replaced, meeting various needs.

[0004] In existing waste gas treatment devices, once the internal activated carbon filter becomes saturated with harmful substances in the waste gas, simply replacing the activated carbon filter to maintain the device's adsorption capacity is not only time-consuming and labor-intensive, but also increases the cost of waste gas treatment. Furthermore, the waste gas treatment devices in the aforementioned comparative cases lack the self-cleaning capability of activated carbon adsorption and desorption. Consequently, long-term use of such devices not only delays their effectiveness but also reduces their overall applicability.

[0005] Therefore, it is necessary to invent an activated carbon adsorption-desorption waste gas treatment device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an activated carbon adsorption-desorption waste gas treatment device. Through a housing cover, pressurized water pump, cleaning tank, cleaning nozzle, exhaust pipe, and steam generator, the waste gas treatment device achieves self-cleaning capability, avoiding the time-consuming and laborious process of disassembling and replacing the activated carbon filter, thus saving on waste gas treatment operating costs. Furthermore, self-cleaning does not delay the device's lifespan, expanding its overall application range. This addresses the problem in existing waste gas treatment devices where, after the internal activated carbon filter becomes saturated with harmful substances in the waste gas, simply replacing the filter to maintain the device's adsorption capacity is time-consuming, labor-intensive, and increases treatment costs. Moreover, the waste gas treatment devices in the aforementioned comparative cases lack the activated carbon adsorption-desorption self-cleaning capability, which, over time, not only delays the device's lifespan but also limits its overall application range.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon adsorption-desorption waste gas treatment device, including a frame for supporting the main body for installing the components of the waste gas treatment device;

[0008] A sludge collection box is located at the bottom of the frame and is used to store impurities after activated carbon desorption. A pretreatment box is fixedly installed on the top of the frame. An exhaust gas inlet pipe is fixedly installed on the outside of the pretreatment box. A box cover is provided on the top of the pretreatment box. A pressurized water pump is fixedly installed on the top of the box cover. One end of the pressurized water pump is fixedly connected to a water inlet pipe, and the other end of the water inlet pipe is fixedly connected to a cleaning box.

[0009] A diversion pipe is located inside the tank cover and is used to deliver cleaning fluid to the nozzle. A cleaning nozzle is fixedly installed on the outside of the diversion pipe. An air supply pipe is fixedly installed on one side of the pretreatment tank. A mounting frame is provided on one side of the pretreatment tank. An activated carbon adsorption chamber is fixedly installed inside the mounting frame.

[0010] A chamber cover is located above the activated carbon adsorption chamber to assist in the discharge of waste gas. An exhaust pipe is located above the chamber cover. A steam generator is located on one side of the activated carbon adsorption chamber, and a steam diversion pipe is fixedly installed at one end of the steam generator.

[0011] Preferably, the number of cleaning nozzles is set to multiple, and the multiple cleaning nozzles are distributed at equal intervals on the cover.

[0012] Preferably, the pretreatment box is provided with a fixing frame inside, and a dust removal filter bag is fixedly installed inside the fixing frame.

[0013] Preferably, the fixing frame is fixedly connected to the pretreatment box, and the dust removal filter bags are distributed at equal intervals on the pretreatment box.

[0014] Preferably, a fixing bolt passes through the exterior of the activated carbon adsorption chamber, and an activated carbon filter screen is movably connected to one end of the fixing bolt.

[0015] Preferably, an electromagnetic control valve is fixedly installed at one end of the exhaust pipe, and an exhaust port is fixedly installed at the other end of the electromagnetic control valve.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model is equipped with a cover, a pressurized water pump, a cleaning tank, a cleaning nozzle, an exhaust pipe, and a steam generator. After the activated carbon filter inside the activated carbon adsorption chamber is full of harmful substances in the waste gas, the exhaust pipe above can be closed. A certain amount of steam is injected from the top of the cover through the steam generator and steam diversion pipe. The steam passes through the activated carbon filter from top to bottom, allowing the activated carbon filter to complete the desorption and cleaning work inside the activated carbon adsorption chamber. The cleaned impurities will flow into the collection box through the bottom pipe. At the same time, the pressurized water pump can draw the cleaning liquid in the cleaning tank and spray it out from the cleaning nozzle to treat the pretreatment tank. With this combination, the waste gas treatment device has the ability to desorb and self-clean, avoiding the tedious operation of disassembling and replacing the activated carbon filter, saving the cost of waste gas treatment. Moreover, self-cleaning does not delay the use of the waste gas treatment device, thus expanding the overall application range of the device.

[0018] 2. This utility model is equipped with a frame, a pretreatment box, a fixing frame, dust removal filter bags, an activated carbon adsorption chamber, fixing bolts, and an activated carbon filter screen. When using this device for waste gas treatment, the pretreatment box, with multiple sets of dust removal filter bags inside, performs preliminary treatment on the waste gas entering from the waste gas inlet pipe, improving the filtration capacity of the pretreatment box and reducing the adsorption pressure of the subsequent activated carbon adsorption chamber. At the same time, if the activated carbon filter screen malfunctions after long-term use, the fixing bolts can be used to facilitate maintenance personnel to freely disassemble the activated carbon filter screen for repair or replacement, thereby ensuring the normal use of the device.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The activated carbon adsorption-desorption waste gas treatment device shown includes a frame 1, which is used to support the main body for installing the components of the waste gas treatment device.

[0029] The sludge collection box 2 is located at the bottom of the frame 1 and is used to store the impurities after activated carbon desorption. A pretreatment box 3 is fixedly installed on the top of the frame 1. An exhaust gas inlet pipe 4 is fixedly installed on the outside of the pretreatment box 3. A box cover 5 is provided on the top of the pretreatment box 3. A pressurized water pump 6 is fixedly installed on the top of the box cover 5. One end of the pressurized water pump 6 is fixedly connected to a water inlet pipe 7, and the other end of the water inlet pipe 7 is fixedly connected to a cleaning box 8.

[0030] The diversion pipe 9 is located inside the cover 5 and is used to deliver cleaning liquid to the nozzle. The cleaning nozzle 10 is fixedly installed on the outside of the diversion pipe 9. An air supply pipe 13 is fixedly installed on one side of the pretreatment box 3. A mounting bracket 14 is provided on one side of the pretreatment box 3. An activated carbon adsorption chamber 15 is fixedly installed inside the mounting bracket 14.

[0031] A chamber cover 18 is positioned above the activated carbon adsorption chamber 15 to assist in the discharge of waste gas. An exhaust pipe 19 is located above the chamber cover 18. A steam generator 22 is located on one side of the activated carbon adsorption chamber 15. A steam diversion pipe 23 is fixedly installed at one end of the steam generator 22, which can close the exhaust pipe 19 above. A certain amount of steam is injected from above the chamber cover 18 through the steam generator 22 and the steam diversion pipe 23. The steam passes through the activated carbon filter 17 from top to bottom, allowing the activated carbon filter 17 to complete the desorption and cleaning work inside the activated carbon adsorption chamber 15.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, multiple cleaning nozzles 10 are arranged at equal intervals on the cover 5. A pressurized water pump 6 draws cleaning fluid from the cleaning tank 8 and sprays it from the cleaning nozzles 10 to treat the pretreatment tank 3. The pretreatment tank 3 has a fixed frame 11 inside, with dust filter bags 12 fixedly installed inside. The pretreatment tank 3 uses multiple sets of dust filter bags 12 to perform preliminary treatment on the exhaust gas entering from the exhaust gas inlet pipe 4, improving the filtration capacity of the pretreatment tank 3. The fixed frame 11 is fixedly connected to the pretreatment tank 3. The dust filter bags 12 are evenly distributed on the pretreatment tank 3, with a corresponding cleaning nozzle 10 above each set of dust filter bags 12, facilitating the spraying of cleaning fluid to complete the self-cleaning of the dust filter bags 12 and improving the cleaning effect.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a fixing bolt 16 passes through the outside of the activated carbon adsorption chamber 15. One end of the fixing bolt 16 is movably connected to the activated carbon filter screen 17. The fixing bolt 16 allows maintenance personnel to easily disassemble the activated carbon filter screen 17 for maintenance or replacement, thereby ensuring the normal use of the device. An electromagnetic control valve 20 is fixedly installed at one end of the exhaust pipe 19, and an exhaust port 21 is fixedly installed at the other end of the electromagnetic control valve 20. The electromagnetic control valve 20 has a simple structure, making it convenient for operators to control and close the exhaust pipe 19 from the outside.

[0034] The working principle of this device is as follows: First, connect the external power supply. Then, connect the device to the external exhaust gas pipe through the exhaust gas inlet pipe 4. The exhaust gas then enters the pretreatment box 3 through the exhaust gas inlet pipe 4. It first passes through multiple sets of dust removal filter bags 12 for pretreatment, adsorbing impurities in the exhaust gas and thus reducing the treatment pressure of the activated carbon adsorption chamber 15. Next, the pretreated exhaust gas enters the two activated carbon adsorption chambers 15 through the gas supply pipe 13. After being adsorbed by the activated carbon filter screen 17, the exhaust gas that meets the qualified emission standards will pass through the chamber. Cover 18 discharges from exhaust port 21, thus completing the waste gas treatment process. After the activated carbon filter 17 inside the activated carbon adsorption chamber 15 is saturated with harmful substances from the waste gas, the operator can use electromagnetic control valve 20 to externally close exhaust pipe 19, then turn on the steam generator 22 to produce steam. A certain amount of steam is injected from above cover 18 through steam diversion pipe 23, passing through the activated carbon filter 17 from top to bottom, allowing the activated carbon filter 17 to... The internal desorption and cleaning process is completed. The cleaned impurities then flow into the collection box 2 through the bottom pipe. The pressure pump 6 is then turned on, drawing cleaning fluid from the cleaning tank 8 through the inlet pipe 7 and spraying it from the cleaning nozzles 10. Each set of dust filter bags 12 has a corresponding cleaning nozzle 10, facilitating the spraying of cleaning fluid to perform self-cleaning on the dust filter bags 12 and improving the cleaning effect. After the pretreatment tank 3 is processed, the cleaning fluid flows into the collection box 2 through the bottom pipe. This gives the waste gas treatment device the ability to desorb and self-clean, avoiding the time-consuming and laborious process of disassembling and replacing the activated carbon filter 17, thus saving on waste gas treatment operating costs. After these operations are completed, the device can continue to absorb waste gas and begin waste gas treatment. Finally, after completing the installation and use of the entire waste gas treatment device according to the above operations, turn off the pressure pump 6 and the steam generator 22. If not used for a long period, simply disconnect the external power supply. This completes the operation of the activated carbon adsorption-desorption waste gas treatment device.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
