[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0017] The embodiment of the utility model comprises a cooling tower 1 and a gas-liquid separation device.

[0018] The gas-liquid separation device is arranged at the top of the cooling tower 1, and includes a gas-liquid polymerization bottom plate 2, a cyclone separation tube 3, a baffle 4, a wire mesh defoaming layer 5, a perforated cover plate 6, a liquid accumulation tank 7 and a liquid discharge pipe 8.

[0019] The gas-liquid polymerization bottom plate 2 is fixed on the cooling tower 1, and the center of the gas-liquid polymerization bottom plate 2 is slightly arched upward to form a cone, which is beneficial to the collection of liquid after gas-liquid separation; an inverted cone-shaped guide cone 10 is fixedly arranged at the lower center of the gas-liquid polymerization bottom plate 2, which is beneficial to the gathering of the lower gas and reduces the gas resistance.

[0020] The gas-liquid polymerization bottom plate 2 is provided with air holes, and the cyclone separation tube 3 is located above the gas-liquid polymerization bottom plate 2. The inlet of the cyclone separation tube 3 is welded and fixed to the gas-liquid polymerization bottom plate 2, and the inlet of the cyclone separation tube 3 is connected to the air hole. A spiral guide plate 9 is fixed inside the cyclone separation tube 3, which can increase the fluid speed, so that the airflow rotates after entering the cyclone separation tube 3, and generates a strong centrifugal force during the rotation process, so as to achieve efficient separation of gas and liquid. There are multiple cyclone separation tubes 3, which are evenly distributed.

[0021] The baffle 4 is located above the gas-liquid polymerization bottom plate 2. The bottom of the baffle 4 is welded and fixed to the upper part of the gas-liquid polymerization bottom plate 2. The outlet of the cyclone separation tube 3 faces the baffle 4. After the liquid-carrying gas is discharged from the cyclone separation tube 3, it is sprayed on the baffle 4 at high speed. Under high-speed impact, the liquid flows downward due to gravity and is enriched at the bottom. The number of cyclone separation tubes 3 corresponds to the number of baffles 4, so as to achieve uniform distribution of airflow and prevent the occurrence of gas deviation. The baffle 4 is arranged vertically, which is conducive to the separation of gas and liquid under different gravitational forces. A certain gap is left between the outer side of the baffle 4 and the inner wall of the cooling tower 1 to facilitate liquid convergence and collection.

[0022] The wire mesh defoaming layer 5 is made of high-quality materials, has good filtering effect and long service life, and is fixed on the top of the baffle 4 by threaded connection, which is convenient for disassembly and replacement.

[0023] The liquid sump 7 is installed at the bottom of the gas-liquid polymerization bottom plate 2 and is located at the connection between the gas-liquid polymerization bottom plate 2 and the cooling tower 1, and is used to collect the separated liquid. The liquid drain pipe 8 is connected to the liquid sump 7, and the liquid drain pipe 8 discharges the liquid in the liquid sump 7 out of the tower body or re-introduces it into the lower part of the tower body.

[0024] The gas-liquid polymerization bottom plate 2 above the liquid accumulation tank 7 is provided with an installation slot, in which a perforated cover plate 6 is detachably installed. The perforated cover plate 6 is provided with a liquid inlet hole, which can effectively prevent foam entrainment and facilitate cleaning.

[0025] The working principle of the utility model is as follows: a mixture containing gas and liquid is introduced into the cooling tower 1. After the gas with liquid is fully cooled and heat-exchanged in the middle and lower part of the cooling tower 1, most of the liquid will fall to the bottom of the tower under the action of gravity, while the upward gas will only carry a small amount of free liquid droplets through the air holes of the gas-liquid polymerization bottom plate 2 into the cyclone separation tube 3, and the centrifugal force generated by the high-speed cyclone rotation in the cyclone separation tube 3 is used to achieve gas-liquid separation. The liquid is thrown to the tube wall of the cyclone separation tube 3 under the action of centrifugal force, and the separated liquid will be brought to the outlet along the tube wall of the cyclone separation tube 3 by the gas, and impact the wall surface of the baffle 4 at high speed. Under the action of gravity, the liquid converges downward along the wall surface of the baffle 4 and falls to the gas-liquid polymerization bottom plate 2, and due to the slope of the gas-liquid polymerization bottom plate 2, it converges to the connection between the gas-liquid polymerization bottom plate 2 and the cooling tower 1, and then enters the liquid accumulation tank 7 through the liquid inlet hole on the perforated cover plate 6 for collection. The liquid in the liquid accumulation tank 7 is discharged from the cooling tower 1 through the drain pipe 8. The gas is almost unaffected by gravity, and after hitting the wall of the baffle 4, it gathers upward and passes through the wire mesh defoaming layer 5.

[0026] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
