[0024] In the embodiment, as shown in Figure 5As shown, the inside of the desiccant box 2 is slidably connected with a filling box 201, and the inside of the filling box 201 is filled with desiccant; it should be noted that after the operator completes the gas-liquid separation operation, the operator can start the air extraction pump 101 and extract the gas in the centrifugal cylinder 8 and the outer tower 4 upward through the air extraction pipe 102, during which the gas is extracted and flows upward, enters the connecting pipe 3, and then enters the inside of the desiccant box 2 connected with the connecting pipe 3, and contacts with the desiccant in the filling box 201, so as to further absorb the tiny water droplets contained in the gas, and then the dried gas continues to move upward and is finally discharged to the outside; in actual use, the sliding connection design of the filling box 201 makes the filling box 201 easily extracted and inserted from the desiccant box 2, so as to facilitate the replacement of the desiccant filled in the inside of the filling box 201, ensure the drying effect, and the desiccant in the inside of the filling box 201 can further absorb the tiny water droplets contained in the gas, so as to improve the gas-liquid separation effect, ensure that the separated gas is drier, reduce the influence of water on the subsequent process or equipment, and help to improve the performance and reliability of the entire gas-liquid separation system.

[0025] In the embodiment, as shown in Figure 5As shown, the rotating mechanism 10 comprises a driving motor 1001, a rotating shaft 1002, a driving gear 1003 and a driven gear 1004 sleeved on the outer wall of the bottom end of the connecting pipe 3, one side of the driven gear 1004 is engaged with the driving gear 1003, the inside of the driving gear 1003 is inserted with the rotating shaft 1002, and the bottom end of the rotating shaft 1002 is rotationally connected to one side of the top of the outer tower 4; it should be noted that when the operator sends the gas mixed with liquid to the inside of the gas inlet pipe 7, and then passes through the filtering mechanism 6 and the gas inlet pipe 5, and finally enters the centrifugal cylinder 8, the operator can start the driving motor 1001 to drive the rotating shaft 1002 inserted with the driving motor 1001 to rotate, and the driving gear 1003 sleeved on the outer wall of the rotating shaft 1002 rotates at the same time, and at the same time, the driven gear 1004 engaged with one side of the driving gear 1003 and the connecting pipe 3 sleeved in the driven gear 1004 are driven to rotate, so that the centrifugal cylinder 8 connected with the connecting pipe 3 rotates synchronously, so that the liquid in the centrifugal cylinder 8 is thrown out of the cylinder under the action of the rotating centrifugal force, and the gas-liquid separation is completed. In actual use, the rotating mechanism 10 can drive the connecting pipe 3 and the centrifugal cylinder 8 to rotate together, so as to generate a rotating centrifugal force, and use the centrifugal force to throw the liquid contained in the gas out of the cylinder, thereby efficiently realizing gas-liquid separation. The whole separation process does not need manual intervention, and the gas-liquid separation can be automatically completed, which improves the separation efficiency and accuracy. At the same time, the rotating mechanism 10 can also provide stable rotating speed and power to ensure that the liquid can be effectively thrown out, further making the separation effect more reliable, and the rotating speed and time of the driving motor 1001 can be adjusted according to the needs to adapt to different gas-liquid separation requirements.

[0026] In this embodiment, as shown in Figure 2 and Figure 3As shown, the top of the centrifugal cylinder 8 is inserted with the bottom end of the connecting pipe 3, and the bottom end of the connecting pipe 3 is provided with a plurality of water holes 801 on the outer wall of the centrifugal cylinder 8; it should be noted that when the operator starts the rotating mechanism 10 to drive the connecting pipe 3 to start rotating, the entire centrifugal cylinder 8 inserted with the connecting pipe 3 will also be driven to rotate synchronously, thereby generating centrifugal force, and the liquid in the centrifugal cylinder 8 will be driven by the centrifugal force to be thrown to the cylinder wall and enter the outer tower 4 outside through the water holes 801, and then be attached to the inner wall surface of the outer tower 4 and slide downward to the bottom under the action of gravity, and then be discharged outward from the liquid discharge pipe 9. In actual use, when the centrifugal cylinder 8 rotates, the centrifugal force generated thereby can make the liquid move outward along the cylinder wall, and the existence of the water holes 801 allows the liquid to pass through, and the gas is left in the centrifugal cylinder 8, so that the liquid can be quickly thrown out of the centrifugal cylinder 8, realizing efficient gas-liquid separation. Because the size and distribution of the water holes 801 are carefully designed, the liquid can smoothly pass through while preventing the liquid from flowing back into the centrifugal cylinder 8 under the action of centrifugal force, which helps to maintain the effect of gas-liquid separation and avoid the liquid from mixing into the gas again, thereby improving the purity of the separation.

[0027] In this embodiment, as shown in Figure 2 and Figure 3 , the bottom wall of the outer tower 4 is provided with a rotating groove 401 in the middle, and the bottom end of the centrifugal cylinder 8 is rotatably connected to the inside of the rotating groove 401; it should be noted that during the period when the operator starts the rotating mechanism 10 and drives the entire centrifugal cylinder 8 to start rotating through the connecting pipe 3, the bottom end of the centrifugal cylinder 8 will synchronously rotate with the inner wall of the rotating groove 401, thereby supporting the entire centrifugal cylinder 8 to realize rotational movement inside the outer tower 4, and then complete the centrifugal separation operation. In actual use, the provision of the rotating groove 401 provides stable support for the centrifugal cylinder 8, so that it can freely and stably rotate inside the outer tower 4, ensuring the smooth progress of the separation process. In addition, the shape and size of the rotating groove 401 match the bottom end of the centrifugal cylinder 8, which can guide the rotational movement of the centrifugal cylinder 8 to rotate along the predetermined trajectory, thereby helping to improve the efficiency of the centrifugal separation and making the gas-liquid separation more thorough.

In actual use, the filtering mechanism 6 can realize multi-stage filtration through the sequentially arranged filter screen plate 604, second filter plate 603 and first filter plate 602, so as to remove impurities and odors of different sizes and types, improve the filtering effect, and further improve the purity of the gas after separation when the clean gas filtered by the filtering mechanism 6 enters the centrifugal cylinder 8 for gas-liquid separation. At the same time, the first filter plate 602, the second filter plate 603 and the filter screen plate 604 are sequentially and slidably connected inside the outer box 601 from top to bottom, so that the operator can take them out at any time for replacement and maintenance, thereby ensuring the persistence of the filtering effect.

[0030] For example, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the operator can first transport the gas mixed with liquid through the gas pipe 7, so that the mixed gas enters into the outer box 601 along the gas pipe 7, and then sequentially contacts the filter screen plate 604, the second filter plate 603 and the first filter plate 602, so as to remove the large-particle impurities, suspended particles and peculiar smell in the mixed gas, and the filtered clean gas continues to be transported upward into the air inlet pipe 5, and enters into the centrifugal cylinder 8 connected with the air inlet pipe 5, at the same time, the driving motor 1001 drives the rotating shaft 1002 connected with the driving motor 1001 to start rotating, and the driving gear 1003 sleeved with the outer wall of the rotating shaft 1002 rotates at the same time, at the same time, the driven gear 1004 meshed with one side of the driving gear 1003 and the connecting pipe 3 sleeved in the driven gear 1004 are driven to rotate, so that the centrifugal cylinder 8 connected with the connecting pipe 3 rotates synchronously, and the liquid in the centrifugal cylinder 8 is driven by the centrifugal force to be thrown to the cylinder wall and enters into the outer tower 4 through the water hole 801, and the gas-liquid separation is completed, and the thrown liquid slides down along the inner wall of the outer tower 4 to the bottom of the outer tower 4 and is discharged outward through the liquid discharge pipe 9, and then the operator can start the air pump 101 and open the air valve, the air pump 101 generates suction force and sucks the gas in the centrifugal cylinder 8 and the outer tower 4 upward through the air suction pipe 102 connected with the air pump 101, during which, the gas is driven to flow upward and enters into the connecting pipe 3, and then enters into the inside of the desiccant box 2 connected with the connecting pipe 3 and contacts the desiccant in the filling box 201, so as to further absorb the micro water droplets in the gas, and then the dried gas continues to move upward and is finally discharged to the outside.
