Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide recovery, in particular to a desiccant quick replacement device for drying equipment used for carbon dioxide recovery. Background Art

[0002] In the carbon dioxide recovery production process, the hydrocarbon substances in the carbon dioxide exhaust gas must first be adsorbed. The gas coming out of the adsorption tower contains a small amount of water vapor, so it must be dried in a drying tower filled with alumina and molecular sieve fillers to prevent water from forming ice in the subsequent system and clogging the pipeline. The drying principle is adsorption drying, and there are many micropores on the surface of the adsorbent that can absorb water vapor.

[0003] After the water vapor adsorbed by the desiccant reaches saturation, the adsorption filter pad on which the desiccant is placed needs to be replaced in time. The existing adsorption filter pad takes a long time to replace, which causes too much undried carbon dioxide to enter the subsequent equipment, causing ice to form inside the equipment and block the channel. Therefore, the equipment needs to be replaced quickly to save the replacement time of the adsorption drying device. Utility Model Content

[0004] The utility model aims at the defects in the prior art and provides a desiccant quick replacement device for drying equipment for carbon dioxide recovery.

[0007] In a preferred embodiment of the utility model, an adsorption filter pad is provided inside the adsorption box, and the adsorption filter pad is filled with a desiccant;

[0008] The desiccant absorbs and dries the moisture in the gas transmitted by the delivery pipe, thereby preventing the water content from being too high. During the subsequent cooling and liquefaction process, the gas will freeze inside the equipment and cause pipeline blockage.

[0009] In a preferred embodiment of the utility model, the clamping claws are arranged at the ends of both sides of the conveying pipe, and the distance between the upper and lower clamping claws matches the height of the frame;

[0010] The main function of the claw is to limit the storage of the spare box and save the volume of the equipment.

[0011] In a preferred embodiment of the utility model, one end of the screw rod penetrates and extends to the outside of one side of the filter bin, and a waist-shaped hole matching with the screw rod is opened on the surface of the filter bin;

[0012] The screw fixes the clamping ring to ensure that the clamping ring clamps and fixes the adsorption box inside the filter bin, and ensures the sealing to prevent the leakage of carbon dioxide.

[0013] In a preferred embodiment of the utility model, guide strips are provided on the top and bottom of the frame, clamping holes matching with the frame are provided on both sides of the filter bin, and one side of the clamping ring contacts one side of the frame.

[0014] The beneficial effects of the utility model are:

[0015] The desiccant quick replacement device of the drying equipment for carbon dioxide recovery is in the internal adsorption box.

The limiting ring 53 is installed on the outside of one side of the frame 51, the limiting plate 54 is fixed on one side of the frame 51, the handle 55 is installed on the outside of the limiting plate 54, the connecting block 56 is fixed on the other side of the frame 51, and the spare box 6 is movably connected to the connecting block 56 on one side of the adsorption box 5 through the clamping shaft 57.

[0022] Specifically, an adsorption filter pad 52 is clamped inside the adsorption box 5, and the adsorption filter pad 52 is filled with desiccant. The claws 7 are arranged at the ends of both sides of the conveying pipe 2, and the distance between the upper and lower claws 7 matches the height of the frame 51. One end of the screw 4 passes through and extends to the outside of one side of the filter bin 1. A waist-shaped hole matching the screw 4 is opened on the surface of the filter bin 1. Guide strips are arranged on the top and bottom of the frame 51. Clamping holes matching the frame 51 are opened on both sides of the filter bin 1, and one side of the clamping ring 3 contacts one side of the frame 51.

[0023] In this embodiment, the delivery pipe 2 is used to transport the carbon dioxide that needs to be dried, the filter chamber 1 adsorbs and dries the water vapor in the carbon dioxide transmitted by the delivery pipe 2, and the moisture inside the carbon dioxide gas passing through the filter chamber 1 is adsorbed by the adsorption box 5, and the adsorption filter pad 52 is placed in the frame 51.

At this time, the spare box 6 is bent out from the claw 7, and after the adsorption filter pad 52 is installed in the spare box 6, the limit ring 53 is installed to fix the adsorption filter pad 52, and then the spare box 6 is rotated around the clamping shaft 57 to make it in the same straight line as the adsorption box 5, the nut on the surface of the screw 4 is loosened, the clamping ring 3 is moved backward, the pressure on the adsorption box 5 is released, the handle 55 on the outside of the adsorption box 5 is pulled, the adsorption box 5 is pulled out of the filter bin 1, and the spare box 6 is drawn into the filter bin 1, thereby realizing the rapid conversion of the adsorption box 5 and the spare box 6, thereby realizing the effect of rapid replacement of the adsorption filter pad 52, and then the internal adsorption component is fixed again by the clamping ring 3 to achieve the purpose of replacement, thereby ensuring the moisture adsorption effect inside the gas.
