Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon adsorption cabinets, in particular to an activated carbon adsorption cabinet. Background Art

[0002] Activated carbon adsorption cabinets play a crucial role in the exhaust gas treatment process. Activated carbon removes pollutants from exhaust gases passing through the cabinet, ensuring that exhaust gas emissions meet emission standards. Controlling the operating temperature of the activated carbon is crucial to ensuring adsorption efficiency and exhaust gas treatment quality. The exhaust gas temperature entering the activated carbon adsorption cabinet should be kept below 40°C. However, activated carbon exhibits a slight chemical adsorption property when adsorbing gas molecules. When adsorbing volatile organic compounds (VOCs), this releases a certain amount of heat, which increases the temperature of the adsorption bed. This, in turn, reduces the activated carbon's adsorption capacity. Furthermore, inlet air temperatures exceeding safety limits can affect the activated carbon's adsorption efficiency and even cause the volatilization of adsorbed impurities and gases, impacting the efficiency and quality of exhaust gas treatment. Existing measures to cool the activated carbon cabinet often involve spraying water into the cabinet to fully cool the activated carbon within.

[0003] However, activated carbon adsorption efficiency is often affected by humidity, particularly in high humidity conditions, where its adsorption rate for volatile organic compounds (VOCs) decreases significantly. When the activated carbon is sprayed throughout the cabinet to cool it, the adsorption efficiency of the activated carbon inside the cabinet decreases significantly, significantly impacting the efficiency of exhaust gas treatment. This solution addresses this technical issue. Utility Model Content

The temperature control of the activated carbon is efficient and fast, avoiding a serious decrease in the activated carbon adsorption efficiency caused by spray cooling. The adsorption efficiency of the activated carbon recovers quickly, and has little impact on the exhaust gas treatment efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0026] See also Figures 1-6An activated carbon adsorption cabinet includes a cabinet body 1, a supporting frame 2 arranged in the cabinet body 1, and a plurality of activated carbon drawers 3 inserted into the supporting frame 2 from the front side of the cabinet body 1.

A plurality of return springs 62 are connected between the other side of the porous plate 6 and the activated carbon drawer 3. A plurality of electromagnet modules 7 corresponding to the activated carbon drawers 3 are provided on the outer side of the back of the cabinet body 1. An electromagnet 71 is provided on the electromagnet module 7 and can be detachably attracted to the magnet 61.

[0029] A spray pipe 10 is provided above the support frame 2 in the cabinet 1 , and is connected to a plurality of spray heads 101 arranged toward the activated carbon in the activated carbon drawer 3 . A drain pipe 11 is provided at the bottom of the cabinet 1 .

[0030] Baffles 21 are vertically arranged on the carrier 2 between the two activated carbon drawers 3 , and top edges of several baffles 21 are higher than the bottom of the spray head 101 .

[0031] Two magnets 34 are respectively provided at both ends of the rear side plate of the activated carbon drawer 3 , and two electromagnets 72 are respectively provided at corresponding positions on the electromagnet module 7 . The electromagnets 72 and the magnets 34 are separably attracted.

[0032] Two slide grooves 32 are provided opposite to each other on the bottom side of the activated carbon drawer 3 , and the porous plate 6 is slidably provided in the slide grooves 32 .

[0033] A sealing strip 33 is provided between the activated carbon drawer 3 and the carrier frame 2 , and the sealing strip 33 is provided on the inner side of the front side panel of the activated carbon drawer 3 .

[0034] A plurality of manhole doors 12 are provided on the top side of the cabinet 1 .

[0035] The specific working process and principle of this utility model:

[0036] Installation of the activated carbon drawer 3: Load the activated carbon into the activated carbon drawer 3, and then insert the activated carbon drawer 3 into the carrier frame 2, so that the sealing strip 33 of the activated carbon drawer 3 is in close contact with the carrier frame 2, and start the electromagnet module 7 through the controller 9, so that the electromagnet 2 72 of the electromagnet module 7 generates magnetic force, and the electromagnet 2 72 generates suction force on the magnet 2 34 on the activated carbon drawer 3, so that the activated carbon drawer 3 presses the sealing strip 33, and the magnetic attraction between the electromagnet 2 72 on the electromagnet module 7 and the magnet 2 34 on the activated carbon drawer is used to make the sealing effect of the activated carbon drawer 3 better, and the installation of the activated carbon drawer 3 is simple and quick.

[0037] After the activated carbon drawer 3 is installed, exhaust gas is introduced into the cabinet 1 through the air inlet pipe 4. The exhaust gas from the air inlet pipe 4 passes through the porous plates 6 of multiple activated carbon drawers 3 and the air vents 31 on the bottom side of the activated carbon drawer 3 in turn, is adsorbed by the activated carbon, and is then discharged through the exhaust pipe 5. When the working temperature of the activated carbon in an individual activated carbon drawer 3 increases due to adsorption heat or the increase in the temperature of the exhaust gas in the intake pipe 4, the temperature of the thermometer 8 of the corresponding activated carbon adsorption cabinet increases, and the thermometer 8 measures and transmits the temperature signal to the controller 9. The controller 9 sends a signal to the corresponding electromagnet module 7, and the electromagnet module 7 starts the electromagnet 71. The electromagnet 71 produces an attraction effect on the magnet 61 on the porous plate 6 on the bottom side of the corresponding activated carbon drawer 3. At this time, the perforated plate overcomes the elastic force of the return spring 62 and slides along the slide groove 32. The holes on the porous plate 6 and the air vents 31 on the activated carbon drawer 3 produce relative displacement, so that the amount of exhaust gas passing through the activated carbon drawer 3 is reduced, thereby reducing the adsorption load of the activated carbon inside it, and the temperature of the activated carbon gradually decreases. At the same time, the activated carbon in the remaining activated carbon drawers 3 bears the above-mentioned exhaust gas volume of the activated carbon with too high a temperature, and the temperature of the corresponding activated carbon is monitored by the thermometer 8 above the remaining activated carbon drawers 3. Until the overheated activated carbon returns to normal temperature, the electromagnet 71 in the electromagnet module 7 is gradually separated from the magnet 61 on the porous plate 6, and the porous plate 6 is reset under the elastic force of the reset spring 62, so that the activated carbon drawer 3 returns to a normal ventilation state.

[0038] By controlling the position of the porous plate 6 relative to the bottom of the activated carbon drawer through an electromagnet 71, the amount of exhaust gas passing through the activated carbon is controlled, the load of the activated carbon is adjusted, and the temperature of the activated carbon is lowered. The temperature control of the activated carbon is efficient and fast, avoiding a serious decrease in the adsorption efficiency of the activated carbon caused by spray cooling. There is no need to spend much time drying the activated carbon, and the adsorption efficiency of the activated carbon recovers quickly, with less impact on the exhaust gas treatment efficiency.

[0039] When the temperature of the activated carbon in the activated carbon drawer 3 continues to rise, the solenoid valve above the corresponding activated carbon drawer 3 is opened by the controller 9, and the corresponding activated carbon is sprayed to cool down through the spray head 101. Since the top edge of the baffle 21 is higher than the bottom of the spray head 101, the water sprayed from the spray head 101 is isolated by the baffle 21, so the spray head 101 has little effect on the activated carbon in the adjacent activated carbon drawer 3, thereby reducing the impact of the spray water on the remaining normally working activated carbon, and has little effect on the adsorption efficiency of the activated carbon adsorption cabinet.

[0040] The water after spraying is discharged through the drain pipe 11, and the activated carbon adsorption cabinet is conveniently inspected and maintained through the manhole door 12.
