[0019] The present application has the following advantages:

[0020] 1. The application integrates carbon dioxide recovery dehydration, secondary drying, recovery storage, and dehydration storage cooling into one, and contributes to carbon dioxide recovery work. The carbon dioxide is dehydrated by a cyclone separator, and then the dehydrated carbon dioxide contacts the adsorbent between the movable cover and the material receiving hopper in the storage tank for secondary dehydration. The secondary dehydrated carbon dioxide is pumped into the gas storage chamber for subsequent use. The water removed from the carbon dioxide is collected in the water storage tank, and the water pump is automatically started when the water level in the water storage tank rises to pump the collected water into the heat absorption pipe to absorb the heat of the carbon dioxide in the gas storage chamber, thereby cooling the stored carbon dioxide, reducing the storage pressure, improving safety, inhibiting chemical activity, and reducing corrosion and reaction.

[0021] 2. In the dehydration process, the rotating shaft drives the reciprocating wire rod two and the support shaft to rotate, thereby driving the three material turning plates to rotate and turning the adsorbent in the material receiving hopper, so that the adsorbent fully absorbs the remaining water attached to the carbon dioxide. The U-shaped rake opening is provided at the lower end of the material turning plate to reduce the resistance of the material turning plate during rotation and turning of the adsorbent, thereby improving the turning effect of the adsorbent. In addition, during the turning of the adsorbent by the material turning plate, the rotation of the rotating shaft drives the reciprocating wire rod two to rotate, thereby driving the screw rod sleeve and the movable cover to move up and down at a small amplitude. During the downward movement of the movable cover, the carbon dioxide is pushed to the adsorbent in the turning process, thereby further allowing the carbon dioxide adsorbent to fully contact and absorb the water, thereby drying and dehydrating the carbon dioxide and improving the carbon dioxide recovery drying and dehydration effect.

[0022] 3. While the material turning plate is rotating and turning the adsorbent in the material receiving hopper, the reciprocating wire rod two drives the screw rod sleeve and the movable cover to move up and down to stir the carbon dioxide. When the movable cover moves downward, the fixed rod and the movable block move downward until they contact the rotating rod, thereby pushing the rotating rod to rotate around the rotating shaft as the pivot point to lift up, causing the torsional spring to be compressed to generate elastic force, thereby driving the knocking ball to move away from the support shaft. When the movable cover moves upward, the movable block moves upward to move away from the rotating rod. Under the action of the elastic force of the torsional spring, the rotating rod is driven to rotate and reset, thereby driving the knocking ball to move and collide with the support shaft. The support shaft is knocked, and the knocking is transmitted to the support block and the material turning plate, so that the adsorbent stuck in the rake opening falls off to avoid the rake opening being blocked. The adsorbent in the material receiving hopper is turned and raked by the material turning plate to fully dry the carbon dioxide for the second time.

[0023] 4. The water level inside the water tank gradually rises. Under the action of buoyancy, the float and the sliding frame are driven upward, which drives the movable rod upward, moves the connecting rod, drives the insulating block and the conductive sheet to rotate clockwise, makes the conductive sheet contact with the conductive plate, and energizes the water pump to send the water inside the water tank into the heat absorption pipe. When the water level inside the water tank rises to a certain position, the water pump starts automatically, and sends the cooled water inside the water tank into the heat absorption pipe to absorb the heat inside the gas storage chamber, cools the carbon dioxide stored inside the gas storage chamber, and prevents water from overflowing from the water tank.
