Description

Technical Field

[0001] The utility model relates to the technical field of VOCs treatment, in particular to an activated carbon regeneration device for VOCs treatment. Background Art

[0002] VOCs refers to volatile organic compounds, which can be divided into alkanes, aromatic hydrocarbons, esters, aldehydes and others. VOCs control refers to the control of volatile organic compounds. VOCs control is a comprehensive environmental protection measure aimed at reducing or eliminating the impact of volatile organic compounds on the environment and human health.

[0003] However, when the existing activated carbon regeneration device for VOCs treatment is used, the activated carbon for VOCs treatment is usually placed in an operating box and high-temperature steam is used to release the substances adsorbed in the activated carbon. However, the activated carbon is prone to accumulation in the operating box, and the high-temperature steam cannot fully contact the activated carbon in the middle position. Moreover, all the activated carbon in the operating box needs to be regenerated before it can be taken out, which has a certain impact on the regeneration efficiency of the activated carbon. At the same time, wastewater is generated during the high-temperature steam regeneration of the activated carbon. The wastewater has a high temperature. Direct discharge will not only pollute the environment, but also dissipate the heat in the wastewater, resulting in a waste of resources. Therefore, an activated carbon regeneration device for VOCs treatment is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide an activated carbon regeneration device for VOCs treatment. The utility model solves the problem that the activated carbon regeneration efficiency of the existing activated carbon regeneration device for VOCs treatment is low during use and the wastewater generated by the activated carbon regeneration cannot be utilized through the arrangement of a frame, a servo motor, a drive plate, a support rod, a fixing plate, a screw rod, a nozzle, a cavity frame A, a cavity frame B, a water tank and a box body.

[0005] The technical solution adopted by the present invention to solve its technical problems is an activated carbon regeneration device for VOCs treatment, comprising a transmission frame and a bottom plate, a cavity frame A for storing steam is fixed by screws at the bottom of the transmission frame, and a fixed pipe A for conveying high-temperature steam is plugged into the bottom of the cavity frame A, a water tank for placing water is fixed by screws at one end of the fixed pipe A away from the cavity frame A, and a heating pipe for heating water is fixed by screws inside the water tank, a conveyor belt for conveying activated carbon for VOCs treatment is provided on the inside of the transmission frame, the top of the transmission frame is bolted to the frame, and the inside of the frame is bolted to a servo motor for providing power, the power output end of the servo motor is connected to a key with a coupling, and the inside of the coupling is fixed with a key. A screw rod is connected with a key, and a threaded sleeve is connected to the outside of the screw rod, and a longitudinally movable driving plate is welded to the outside of the threaded sleeve, a cavity frame B is fixed with screws on one side of the driving plate, and a nozzle for spraying steam on the activated carbon is fixed with screws on the outside of cavity frame A and cavity frame B, a fixed pipe B connected to the water tank is fixed with screws on the outside of cavity frame B, a support rod is welded to the outside of the driving plate, and a fixed plate for flattening the activated carbon on the conveyor belt is fixed with screws on the end of the support rod away from the driving plate, a box for collecting wastewater generated by steam activation of activated carbon is fixed with screws on one side of the bottom plate, and the box surrounds the outside of the water tank, and a heating plate for heating the wastewater entering the box is fixed with screws on the inside of the box.

[0006] By adopting the above technical solution, when the activated carbon used for VOCs treatment is to be regenerated, the activated carbon is first placed on the conveyor belt in the transmission frame, and then the external controller causes the servo motor in the frame to convert the received electrical energy into mechanical energy, the coupling on the servo motor drives the screw to rotate, the threaded sleeve outside the screw drives the drive plate to move, and the support rod outside the drive plate drives the fixed plate to move, so that the fixed plate moves to the top of the conveyor belt, and then the water in the water tank is heated at high temperature through the heating pipe, and then the high-temperature steam generated by the heating is transported to the cavity frame A and the cavity frame B respectively through the fixed pipe A and the fixed pipe B, and at the same time, the external controller controls the conveyor belt to move, so that the activated carbon is transported into the frame, and the fixed plate flattens the activated carbon on the conveyor belt to avoid accumulation of the activated carbon, and then the nozzles on the cavity frame A and the cavity frame B spray high-temperature steam on the surface of the activated carbon to release the substances adsorbed in the activated carbon, thereby achieving the regeneration effect and improving the regeneration efficiency of the activated carbon;

[0007] When activated carbon is regenerated with high-temperature steam, wastewater is generated around the activated carbon, and then the wastewater flows into the box on the bottom plate. The box is located outside the water tank. The heat in the wastewater is then transferred to the inside of the water tank. At the same time, the heating plate in the box heats the wastewater, making the wastewater at a higher temperature, thereby facilitating the full utilization of the heat in the wastewater, improving resource utilization, and avoiding wastewater pollution to the environment.

[0026] During use, when the activated carbon for VOCs treatment is to be regenerated, the activated carbon is first placed on the conveyor belt 1 in the transmission frame 3, and then the external controller causes the servo motor 24 in the frame 12 to convert the received electrical energy into mechanical energy. The coupling 22 on the servo motor 24 drives the screw rod 18 to rotate, and the threaded sleeve 19 outside the screw rod 18 drives the drive plate 15 to move. The support rod 16 outside the drive plate 15 drives the fixed plate 17 to move, so that the fixed plate 17 moves to the top of the conveyor belt 1, and then the water in the water tank 9 enters through the heating pipe 23. High-temperature heating is performed, and then the high-temperature steam generated by the heating is transported to the chamber frame A5 and the chamber frame B20 respectively through the fixed pipe A8 and the fixed pipe B11.

[0035] During use, when the drive plate 15 outside the threaded sleeve 19 moves in the frame 12, the external fixing sleeve 14 of the drive plate 15 slides outside the slide rod 13 in the frame 12, thereby improving the stability of the drive plate 15 moving in the frame 12.

[0036] In order to use the electrical equipment to work properly, for example, Figure 1 、 Figure 2 and Figure 3As shown, the present invention further includes that the input ends of the heating tube 23, the servo motor 24 and the heating plate 7 are all electrically connected to the power supply end of the external power supply.

[0037] When in use, connect the external power supply to make the electrical equipment work normally.

[0038] When the utility model is in use, when the activated carbon for VOCs treatment is to be regenerated, the activated carbon is first placed on the conveyor belt 1 in the transmission frame 3, and then the external controller causes the servo motor 24 in the frame 12 to convert the received electrical energy into mechanical energy, the coupling 22 on the servo motor 24 drives the screw rod 18 to rotate, the threaded sleeve 19 outside the screw rod 18 drives the drive plate 15 to move, the support rod 16 outside the drive plate 15 drives the fixed plate 17 to move, so that the fixed plate 17 moves to the top of the conveyor belt 1, and then the water in the water tank 9 passes through the heating pipe 23 is heated at high temperature, and the high-temperature steam generated by the heating is transported to chamber frame A5 and chamber frame B20 respectively through fixed pipe A8 and fixed pipe B11.
