Description

Technical Field

[0001] This utility model relates to the field of adsorbent regeneration technology, and in particular to an adsorbent regeneration device for a methanol benzene removal system. Background Technology

[0002] An adsorbent is a solid substance that can effectively adsorb certain components from a gas or liquid. It is a solid substance with a large specific surface area, suitable pore structure and surface structure. It has a strong adsorption capacity for adsorbates and generally does not react chemically with the adsorbate or the medium. When the adsorbent is saturated, it needs to be desorbed and regenerated.

[0003] Existing adsorbent regeneration technologies, such as the prior art with application number CN200810226410.2, include a housing, loading and unloading port, upper chamber, lower chamber, bottom plate, thermocouple, and temperature controller. By regenerating the adsorbent through a desorption regeneration device, not only can the adsorption capacity of the adsorbent be fully utilized in each adsorption operation, but the service life of the adsorbent can also be extended to the maximum extent.

[0004] However, existing technologies make it difficult to cool the adsorbent after thermal regeneration, which greatly prolongs the total regeneration time and reduces the regeneration efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an adsorbent regeneration device for a methanol benzene removal system that improves the efficiency and quality of adsorbent regeneration and reduces energy consumption.

[0006] This utility model discloses an adsorbent regeneration device for a methanol-to-benzene desorption system, comprising a heat preservation mechanism; it also includes a loading and unloading mechanism, a draining mechanism, a heating mechanism, a cooling mechanism, and an air-cooled drying mechanism. The loading and unloading mechanism is installed on the heat preservation mechanism, the draining mechanism is installed on the loading and unloading mechanism, the heating mechanism is installed inside the heat preservation mechanism, the cooling mechanism is installed inside the heat preservation mechanism, and the air-cooled drying mechanism is installed on the heat preservation mechanism. The heat preservation mechanism facilitates overall heat preservation, the loading and unloading mechanism facilitates the loading and unloading of the adsorbent, the draining mechanism facilitates the draining and drying of the adsorbent, and the heating mechanism heats the adsorbent. The system includes a cooling mechanism for water cooling of the adsorbent and an air-cooled drying mechanism for air cooling. An insulation mechanism facilitates overall insulation, providing space for adsorbent regeneration. A loading and unloading mechanism facilitates the loading and unloading of the adsorbent, improving convenience. A draining mechanism facilitates the draining and drying of the adsorbent. A heating mechanism heats the adsorbent for desorption. The cooling mechanism uses water cooling to improve the efficiency of adsorbent cooling. The air-cooled drying mechanism can perform both air cooling and water cooling followed by drying, improving practicality and adsorbent regeneration efficiency.

[0007] Preferably, the insulation mechanism includes a regeneration box, an insulation door, multiple fixed frames, a rotating seat, a threaded rod, a rotating handle, and a limiting plate. The insulation door is hinged and rotatably mounted on the regeneration box. The fixed frames are mounted on the regeneration box and the insulation door. The rotating seat is rotatably mounted on the fixed frames of the insulation door. The threaded rod is threadedly mounted on the rotating seat. The rotating handle is mounted on the threaded rod. The limiting plate is rotatably mounted on the other end of the threaded rod. When the regeneration box needs to be closed for insulation, the insulation door is rotated. When the fixed frames on the regeneration box and the insulation door are aligned, the rotating seat is rotated so that the threaded rod passes through the two fixed frames. Then, the rotating handle is rotated so that the threaded rod rotates. Through the threaded connection, the limiting plate approaches the rotating seat. The limiting plate and the threaded rod then fix the two fixed frames, thereby completing the closure of the insulation door.

[0008] Preferably, the loading and unloading mechanism includes a guide block and a loading and unloading sliding plate. The guide block is installed on the inner wall of the regeneration box, and the loading and unloading sliding plate is slidably installed on the guide block. The loading and unloading sliding plate slides on the guide block, which facilitates the loading and unloading of the adsorbent.

[0009] Preferably, the draining mechanism includes a draining box, a drainage trough, a water guide trough, and a draining plate. The draining box is installed on the loading and unloading sliding plate. The draining box is equipped with a drainage trough and a water guide trough, which are connected. The draining plate is installed on the inner wall of the draining box, and a drain outlet is provided on the regeneration box. By placing the adsorbent on the draining plate, after the cooling mechanism cools the adsorbent with water, the adsorbent is drained through the draining plate. The water enters the drainage trough through the water guide trough, exits the draining box through the drainage trough, enters the regeneration box, and is discharged through the drain outlet of the regeneration box.

[0010] Preferably, the heating mechanism includes a heat exchange box, a flow channel, a heating oil tank, a first pump body, a second pump body, an oil guide pipe, a first regulating valve, and a second regulating valve. The heat exchange box is installed on the inner wall of the regeneration tank and slides relative to the loading and unloading sliding plates. A flow channel is provided inside the heat exchange box. The heating oil tank is installed on the outer wall of the regeneration tank and is equipped with a partition and a heating plate. The partition divides the heating oil tank into a first oil tank and a second oil tank. The first pump body and the second pump body are respectively installed on the outer walls of the first oil tank and the second oil tank. One end of the oil guide pipe is installed on the second pump body. The first pump body is connected to the first regulating valve through a pipe, and the other end of the oil guide pipe is connected to the first regulating valve. The first regulating valve is connected to one end of the flow channel through a second pipe, and the second regulating valve is connected to the other end of the flow channel through a second pipe. The second regulating valve is provided with two branch oil pipes connected to the first oil tank and the second oil tank. The system is interconnected. First, oil is added to the first oil tank, which is then heated by turning on the heating plate. Next, the second pump is turned on, allowing the oil to flow through the guide pipe and the first regulating valve into the flow channel. The oil then flows back to the first oil tank via the second regulating valve. When the adsorbent regeneration is complete and cooling is required, the second regulating valve is adjusted to allow the oil flowing out of the flow channel to enter the second oil tank for storage until the oil in the first oil tank is drained. At this point, cooling the adsorbent does not require cooling the oil, and the oil remains hot when heating the next batch of adsorbent, improving cooling efficiency and reducing energy consumption. When heating and desorbing the next batch of adsorbent, the first regulating valve allows the oil in the second oil tank to enter the flow channel and return to the second oil tank. When cooling the adsorbent is required, the second regulating valve is adjusted to allow the returned oil to enter the first oil tank.

[0011] Preferably, the cooling mechanism includes a water distribution tank, a nozzle, and a water pump. The water distribution tank is installed on the inner wall of the regeneration tank and is located above the draining tank. The nozzle is installed on the water distribution tank, and the water pump is installed on the outer wall of the regeneration tank. The water pump is connected to the water distribution tank and is also connected to a water pipe from an external water source. Water is added to the nozzle by turning on the water pump, and then sprayed onto the adsorbent by the water pump, thereby rapidly cooling the adsorbent.

[0012] Preferably, the air-cooled drying mechanism includes an air duct and an exhaust fan. The air duct is equipped with a ventilation valve, and the exhaust fan is installed on the air duct. By opening the ventilation valve and the exhaust fan, outside air is introduced into the regeneration box to air-cool and dry the adsorbent.

The loading and unloading sliding plate 22 slides on the guide block 21 to facilitate the loading and unloading of the adsorbent and improve convenience. By placing the adsorbent on the drain plate 34, after the cooling mechanism 05 cools the adsorbent with water, the adsorbent is drained through the drain plate 34.

When the adsorbent regeneration is complete and cooling is required, the oil exiting the flow channel 42 is adjusted by the second regulating valve 48 to enter the second oil tank for storage until the oil in the first oil tank is drained. At this point, cooling the adsorbent does not require cooling the oil, and the oil remains hot when heating the next batch of adsorbent, improving cooling efficiency and reducing energy consumption. When the adsorbent is heated for desorption, the oil in the second oil tank enters the flow channel 42 through the first regulating valve 47 and returns to the second oil tank. When it is necessary to cool the adsorbent, the second regulating valve 48 is adjusted so that the returned oil enters the first oil tank. Water is added to the nozzle 52 by turning on the water pump 53, and then sprayed onto the adsorbent by the water pump 53 to quickly cool the adsorbent.
