Description

Technical Field

[0001] This utility model relates to the field of welded wire mesh technology, and in particular to a highly safe activated carbon adsorption vapor desorption condensation and recovery device. Background Technology

[0002] Activated carbon adsorption is a common technology for treating organic waste gas. It utilizes the adsorption properties of activated carbon to adsorb and retain harmful substances in the waste gas, then uses vapor desorption to release the adsorbed organic components, which are then condensed and recovered for resource reuse. However, traditional activated carbon adsorption-vapor desorption-condensation-recovery devices have several safety hazards during operation:

[0003] First, it is difficult to precisely control the steam pressure and temperature during the desorption process. Excessive pressure may cause the equipment to break, and excessive temperature may cause the activated carbon to spontaneously combust.

[0004] Secondly, the lack of an effective emergency response mechanism means that when equipment malfunctions, there is no timely response, which can easily escalate safety accidents.

[0005] Third, the equipment's overall explosion-proof and heat insulation design is insufficient, further increasing operational risks. Utility Model Content

[0023] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0024] like Figures 1 to 3 As shown, this utility model includes an activated carbon box 1, which has five sets of components. Several sets of mounting frames 8 are installed inside the activated carbon box 1, and activated carbon layers 9 are placed on the mounting frames 8. An air inlet pipe 10 is fixedly connected to the upper end of the activated carbon box 1. A first valve 15 is installed on the outer side of the air inlet pipe 10. A conveying pipe 19 is connected to the outer side of the air inlet pipe 10. A pretreatment device 20 is connected to the left side of the conveying pipe 19, and a VOC waste gas inlet pipe 21 is connected to the left side of the pretreatment device 20. An outlet pipe 12 is fixedly connected to the lower end of the activated carbon box 1, and a third valve 15 is installed on the outer side of the outlet pipe 12. Valve 17, the lower end of the outlet pipe 12 is fixedly connected to the output pipe 28, the upper right side of the output pipe 28 is fixedly connected to the chimney pipe 29, the VOC waste gas enters the pretreatment equipment 20 through the VOC waste gas inlet pipe 21 and then enters the inlet pipe 10 through the conveying pipe 19. Four of the five activated carbon boxes 1 are always performing adsorption, and then one group is performing desorption. Open the corresponding first valve 15 so that the VOC waste gas enters the activated carbon box 1 and is adsorbed by the activated carbon layer 9. Then open the third valve 17 so that the treated gas is discharged from the device through the outlet pipe 12, the output pipe 28 and the chimney pipe 29.

[0025] like Figures 1 to 3As shown, the upper right part of the activated carbon box 1 is connected to an exhaust gas pipe 11. A second valve 16 is installed on the outside of the exhaust gas pipe 11. The upper end of the exhaust gas pipe 11 is connected to a high-concentration exhaust gas pipe 22. The lower end of the high-concentration exhaust gas pipe 22 is connected to a catalytic combustion furnace 23. The right side of the catalytic combustion furnace 23 is connected to a fresh air heat exchange device 25 through a heat exchange pipe 24. The fresh air heat exchange device 25 is externally connected to a fan 26. The upper end of the fresh air heat exchange device 25 is fixedly connected to a hot gas transmission pipe 27. The lower left part of the activated carbon box 1 is connected to a set of hot gas pipes 13. A fourth valve 18 is provided on the outside of the hot air pipe 13, and a hot air transmission pipe 27 is connected to the outside of the hot air pipe 13. By opening the corresponding fourth valve 18 on the activated carbon box 1 that needs to be desorbed, the fresh air heat exchanger 25 delivers hot air into the corresponding activated carbon box 1 to desorb the internal activated carbon layer 9. At this time, the first valve 15 and the third valve 17 are closed, and the second valve 16 is opened, so that the high-concentration VOC waste gas generated by desorption enters the catalytic combustion furnace 23 through the waste gas pipe 11 and the high-concentration waste gas pipe 22 for catalytic combustion to generate heat energy, which is then circulated to the fresh air heat exchanger 25 for desorption treatment.

[0026] like Figure 3 As shown, an outer shell 2 is provided on the outside of the activated carbon box 1. The gap between the outer shell 2 and the activated carbon box 1 is filled with an explosion-proof layer 3 to prevent damage from an explosion. A pressure sensor 6 and a temperature sensor 7 are provided in the upper left of the interior of the activated carbon box 1 to detect the pressure and temperature inside the activated carbon box 1. A hollow groove 4 is provided on the inner wall of the activated carbon box 1. A cooling pipe 5 is provided in the hollow groove 4. The cooling pipe 5 is connected to a cooling medium circulation pump. A nitrogen pipe 14 is connected to the lower right of the activated carbon box 1.

Nitrogen gas is introduced to prevent fire and explosion.

[0027] like Figure 1 and Figure 4 As shown, a sealing and protective pipe 30 is sealed and installed on the outside of the high-concentration exhaust gas pipe 22. A middle space gap 31 is formed between the sealing and protective pipe 30 and the high-concentration exhaust gas pipe 22. Several sets of VOC exhaust gas detection sensors 32 are arranged in the middle space gap 31. The VOC exhaust gas detection sensors 32 are fixedly installed on the inner wall of the sealing and protective pipe 30. A set of connecting pipes 33 are fixedly connected to the upper end of the sealing and protective pipe 30. An air pump 34 is connected to the outside of the connecting pipes 33. The air pump 34 is used to draw air outward. The VOC exhaust gas detection sensors 32 detect whether the high-concentration exhaust gas pipe 22 is leaking. When a leak occurs, the sealing and protective pipe 30 prevents the exhaust gas from spreading outward. Then, the air pump 34 is started to draw out the exhaust gas for treatment.

[0028] In use, this utility model uses pressure sensor 6 and temperature sensor 7 to detect the pressure and temperature inside the activated carbon box 1. When the pressure and temperature are too high, the inside of the activated carbon box 1 is cooled by cooling pipe 5. Nitrogen gas is introduced to prevent fire and explosion. The explosion-proof layer 3 is set to prevent damage caused by explosion. The sealing and protective pipe 30 set on the outside of the high-concentration waste gas pipe 22 prevents the waste gas from spreading outward, thus playing a protective role.
