Description

Technical Field

[0001] The utility model relates to the technical field of gas separation, in particular to a mixed gas multi-stage separation mechanism. Background Art

[0002] Mixed gas usually refers to a mixture of several gases containing two or more effective components, or a gas that is a non-effective component but whose content exceeds the specified limit. The existing mixed gas separation generally uses the method of condensing gases at different temperatures into water droplets for separation.

[0003] In the prior art, a Chinese patent document with patent number CN215463088U proposes a gas separation device, including an air inlet box, a cooler, a compressor, a distillation tower, an air outlet box and a collector, wherein the air inlet box has an air inlet and an air outlet, the air inlet box is connected to the inlet end of the cooler through a pipeline, the outlet end of the cooler is connected to the inlet end of the compressor through a pipeline, the outlet end of the compressor is connected to the inlet end of the distillation tower through a pipeline, the outlet end of the distillation tower is connected to the inlet end of the air outlet box through a pipeline, a first outlet end is provided at the top of the air outlet box, a second outlet end is provided at the bottom, and the first outlet end is connected to the collector through a pipeline. The utility model can pre-treat the gas through the air inlet box, the compressor The compressor compresses the gas into liquid and enters the distillation tower. The different boiling points of the gases are used to evaporate them and discharge them into the air outlet box in sequence. The gas is screened again in the air outlet box by a screening component, and the obtained high-purity gas is discharged into a collector for storage, which is convenient for use. However, there are still problems in actual use. After the liquid condenses, the water droplets of the gas separation device fall and collect slowly, and will accumulate on the inner wall with a lower temperature, making it difficult for the gas to contact the inner wall surface for cooling, thereby affecting the temperature of more gases and reducing the condensation rate, resulting in a lower separation efficiency of the mixed gas. Therefore, the utility model proposes a multi-stage separation mechanism for mixed gases to meet the needs of accelerating the gas condensation rate and improving the gas separation efficiency. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a mixed gas multi-stage separation mechanism to improve the purity and quality of the mixed gas during separation.

[0005] Based on the above-mentioned purpose, the utility model provides a mixed gas multi-stage separation mechanism, including a support frame, a separation tank body is fixedly connected to the top of the support frame, an air inlet is fixedly connected to the top of the separation tank body, an air outlet is fixedly connected to one side of the separation tank body, a plurality of connecting plates are fixedly connected to the inner wall of the separation tank body, a plurality of separation components are fixedly connected to the bottom of the connecting plate, and the separation component is used to separate different components of the mixed gas; the separation component includes a plurality of support rods fixedly connected to the bottom of the connecting plate, a connecting arm is fixedly connected to one end of the support rod, a supporting ring is fixedly connected to one side of the connecting arm, a fixed plate is fixedly connected inside the support ring, a threaded rod is fixedly connected to the bottom of the fixed plate, a rotating ring is threadedly sleeved on the threaded rod, a guide rod is fixedly connected to one end of the guide rod, a cleaning plate is fixedly connected to the guide rod, a telescopic spring is fixedly sleeved on the guide rod, one end of the telescopic spring is fixedly connected to the rotating ring, and the other end of the telescopic spring is fixedly connected to one side of the cleaning plate.

[0006] Preferably, a connecting rod is fixedly connected to the top of the inner wall of the separation tank body, and a rotating fan is rotatably sleeved on the connecting rod.

[0007] Preferably, a guide cylinder is fixedly connected to the bottom of the connecting plate, the guide cylinder is located at the central axis of the separation tank body, and the guide cylinder is a trumpet-shaped structure with an opening facing upward.

[0008] Preferably, a guide tube is fixedly connected to the top of the support ring, the guide tube is in a cone shape expanding outward, and the guide tube is matched with the bottom of the guide tube.

[0009] Preferably, a thread groove is provided on the surface of the threaded rod, the thread groove is a repeated double thread structure, and the bottom of the thread groove is fixedly connected to a limit plate.

[0013] Preferably, the flow groove is in contact with the surface of the adsorption block.

[0014] Beneficial effects of the utility model:

[0015] 1. When the mixed gas enters the separation tank body, the mixed gas drives the driving blades to rotate around the axis of the threaded rod. When the rotating ring rotates, the guide rod can rotate synchronously, thereby driving the cleaning plate to rotate in a state of being in contact with the inner wall of the separation tank body, so that when the mixed gas contacts different adsorption blocks, the mixed gas can be separated, thereby improving the separation effect. At the same time, because the impurities contained in the mixed gas contact and adhere to the surface of the adsorption block, the adsorption effect of the adsorption block is reduced. The surface of the adsorption block is cleaned by the cleaning plate, thereby ensuring the cleanliness of the surface of the adsorption block, thereby improving the separation effect of the mixed gas.

[0016] 2. When the mixed gas enters through the air inlet on the top of the separation tank body, the mixed gas contacts the rotating fan, which can slow down the speed at which the mixed gas enters the separation tank body. At the same time, the rotating fan rotates to allow the mixed gas to evenly enter the connecting disk. The upward trumpet-shaped structure of the opening of the guide cylinder allows the gas passing through the connecting disk to evenly enter the guide cylinder, thereby increasing the retention time of the mixed gas in the separation tank body, thereby further improving the separation effect of the mixed gas.

Finally, the separated different components are discharged respectively through the air outlet 4, completing the separation of the mixed gas. The different components in the mixed gas can be effectively separated, and the purity and quality of the gas can be improved.
