Description

Technical Field

[0001] The present invention relates to the technical field of waste gas adsorption, and in particular to a vehicle-mounted waste gas recovery device with an adsorption function. Background Art

[0002] An adsorption-based exhaust gas recovery device is a device specifically designed to recover and treat exhaust gas during the loading process. Its core feature lies in its adsorption function. It utilizes adsorbents (such as activated carbon and molecular sieves) to adsorb, separate, and recover exhaust gas generated during the loading process. This device efficiently removes harmful substances from the exhaust gas, such as volatile organic compounds (VOCs), sulfur dioxide, and nitrogen oxides, converting them into harmless substances or recycling them. It also recovers energy, such as heat and chemical energy, from the exhaust gas, enabling resource recycling. The operating principle of an adsorption-based exhaust gas recovery device is primarily based on the physical and chemical adsorption of the adsorbent. As exhaust gas passes through the device, harmful substances are adsorbed by the active sites on the adsorbent's surface, thereby purifying the exhaust gas. When adsorption reaches saturation, regeneration is required. Thermal desorption is typically used to remove the harmful substances adsorbed on the adsorbent and restore its adsorption properties.

[0003] However, when the existing loading exhaust gas recovery device with adsorption function is in use, the activated carbon is not uniform and sufficient when adsorbing the exhaust gas, which affects the efficiency and effect of the adsorption. At the same time, when the activated carbon is desorbed, the activated carbon piles up, which is not convenient for heating the internal activated carbon. It is not only not convenient and fast enough, but also has a poor effect, which will also affect the efficiency and effect of subsequent adsorption. In addition, during transportation and use, due to friction and vibration, some fine particles on the surface of the carbon block may fall off, thereby generating dust and debris, which is not convenient for removing the debris and also affects the efficiency and effect of adsorption.

At the same time, the air outlet is aligned with the exhaust pipe, and the air inlet is aligned with the air inlet pipe. Then, the two second electromagnets are powered off. At this time, the second iron block is no longer attracted, so that the two sealing sleeves can move toward the direction of the moving cylinder under the action of the third spring, and the sealing sleeves cover the air inlet and the air outlet to seal. Then, the exhaust gas enters the filter through the intake pipe for filtration, removes large particles and moisture in the exhaust gas, prevents clogging of the activated carbon and improves its adsorption efficiency. Then, the exhaust gas is filtered. The air enters between the moving cylinder and the rotating cylinder through the air intake pipe. At the same time, the motor is started. The rotation of the motor drives the rotation of the gear, thereby driving the ring gear and the rotating shaft to rotate, and then driving the rotating cylinder and the first baffle to rotate, which can flip the activated carbon between the rotating cylinder and the moving cylinder back and forth, making the adsorption more uniform, and making the adsorption efficiency higher and the effect better. In addition, the second circulation pump is started, so that the coolant in the cold liquid tank can enter the cooling pipe after passing through the second circulation pump and the second liquid supply pipe, and circulate back to the cold liquid tank through the second return liquid pipe, thereby facilitating the cooling of the activated carbon between the rotating cylinder and the moving cylinder, and making the cooling efficiency higher and the effect better, thereby improving the efficiency and effect of adsorption.

At this time, the debris in the collecting trough can fall into the collecting box for collection, and the weight of the debris is detected by the weighing module, so as to facilitate the removal and collection of the debris. Moreover, when there is a lot of debris, the activated carbon is replaced to ensure the efficiency and effect of adsorption.

[0019] (3) This loading waste gas recovery device with adsorption function is equipped with a first liquid supply mechanism, etc. When the moving cylinder moves into the heating tube, the sealing block can seal the air inlet and the air outlet. Then, the first circulation pump is started.

[0047] During adsorption, the moving cylinder 21 moves into the cooling tube 26. At the same time, the end of the push rod 301 abuts against the inner wall of the box body 1, so that the moving cylinder 21 can be pushed to move through the connecting plate 302, so that the second through hole 32 is staggered with the first through hole 29. At this time, the rotating cylinder 28 and the moving cylinder 21 are kept in a sealed state. At the same time, the first spring 403 is compressed. After the adsorption is completed, the moving cylinder 21 is driven by the moving module 20 to move into the heating tube 25. The sealing block 24 can block and seal the air inlet 22 and the air outlet 23. At this time, the annular cover 31 can be moved and reset under the action of the first spring 403, so that the second through hole 32 is aligned with the first through hole 29, so that the debris in the activated carbon can pass through the first through hole 2 9 and the second through hole 32 and then fall into the annular cover 31, and when the rotating cylinder 28 rotates, it can drive the annular cover 31 and the second baffle 203 to rotate, so that the debris can be pushed and fall into the collecting tank 202 for collection. Then, the first electromagnet 705 is energized. After the first electromagnet 705 is energized, it can attract the first iron block 704, so that the connecting block 602 and the sealing plate 601 move upward. At the same time, the second spring 703 is compressed. At this time, the debris in the collecting tank 202 can fall into the collecting box 205 for collection, and the weight of the debris is detected by the weighing module 206, so as to facilitate the removal and collection of the debris. Moreover, when there is a lot of debris, the activated carbon is replaced to ensure the efficiency and effect of adsorption.

[0048] Moreover, when the movable cylinder 21 moves into the heating tube 25, the sealing block 24 can seal the air inlet 22 and the air outlet 23, and then, the first circulation pump 803 is started. At this time, the high-temperature liquid in the hot liquid tank 801 can be transported to the heating tube 25 through the first liquid supply pipe 804, and then circulated to the hot liquid tank 801 through the first return liquid pipe 802. In this way, the activated carbon between the movable cylinder 21 and the rotating cylinder 28 can be heated at high temperature, and the efficiency and effect of heating are guaranteed, thereby facilitating the desorption of the activated carbon. At the same time, the fan 33 is started to perform the exhaust operation, so that a negative pressure is generated in the annular cover 31, which is not only convenient for the collection of debris, but also convenient for the desorption of the waste gas in the activated carbon. The desorbed waste gas can be filtered by the filter 34 and then discharged and collected through the collection pipe 35, thereby facilitating the desorption of the activated carbon and ensuring the desorption effect, thereby ensuring the efficiency and effect of subsequent adsorption.

[0049] When the exhaust gas is adsorbed, the adsorbed gas is discharged through the exhaust pipe 14 and the first solenoid valve 15. At the same time, the exhaust gas is detected by the detection sensor 18. When the detection fails, the first solenoid valve 15 is closed and the second solenoid valve 16 is opened, so that the gas can enter the intake pipe 11 through the return pipe 17 for re-adsorption, and determine whether the activated carbon needs to be replaced. When the activated carbon needs to be replaced, the mobile cylinder 21 can be removed from the mobile module 20, and the activated carbon can be poured out through the air inlet 22 and the air outlet 23 and new activated carbon can be added.
