Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Any process or method descriptions in flow charts or otherwise described herein may be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps of the process, and the scope of the preferred embodiments of the present invention includes other implementations in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the embodiments of the present invention.

As shown in figure 1, the utility model provides an anti-icing stifled carbon dioxide condensing system, including carbon dioxide storage tank 1, filter 2, condenser 3 and the liquid carbon dioxide storage tank 4 that connect gradually, filter 2 with be provided with vapour and liquid separator 5 between the condenser 3 for separate out the vapor that thoughtlessly has in the carbon dioxide.

The working process of the existing carbon dioxide condensing system is as follows: heating carbon dioxide storage tank 1 earlier, inside pressure risees, and the carbon dioxide gas gets into the pipeline and outwards diffuses, and pipe connection filter 2 separates some impurity through filter 2, then carries out condensation liquefaction carbon dioxide gas in rethread pipeline gets into condenser 3, and liquid carbon dioxide gets into in liquid carbon dioxide storage tank 4 at last. However, the carbon dioxide gas is mixed with water vapor, and in the process of condensing the carbon dioxide gas in the condensing pipe of the condenser 3, the mixed water vapor is directly desublimated in the condensing pipe to generate ice attached to the condensing pipe, and the ice blocking phenomenon occurs in the condensing pipe along with the long-time accumulation, so that the carbon dioxide gas which needs to be condensed later cannot pass through, and the condensing work cannot be carried out. This scheme is through setting up a vapour and liquid separator 5 between condenser 3 and separator, and vapour and liquid separator 5 can regard as a precooling apparatus, separates out the vapor that mixes in the carbon dioxide through the liquefaction in advance, and then avoids the condenser pipe in the condenser 3 to take place the stifled phenomenon of ice.

As shown in fig. 2, the gas-liquid separator 5 includes a tank body, a plurality of metal balls 7 arranged in the tank body and a heat exchange pipe 6 arranged on the periphery of the tank body, a drain valve is arranged at the bottom of the tank body, the gas-liquid separator 5 is provided with an air inlet pipe 8 and an air outlet pipe 9, a port of the air inlet pipe 8 is arranged at the lower end inside the gas-liquid separator 5, and a port of the air outlet pipe 9 is arranged at the upper end inside the gas-liquid separator 5.

Carbon dioxide gas enters the lower end of the shell of the gas-liquid separator 5 through the gas inlet pipeline 8, the carbon dioxide gas moves upwards, heat in the shell is absorbed through the heat exchange pipe 6, the internal temperature of the gas-liquid separator 5 is lower, water vapor can be atomized, when the carbon dioxide gas contacts the metal ball 7, the atomized water vapor is adsorbed on the surface of the metal ball 7 and is arranged into a sphere shape because the surface area of the ball is larger than that of other shapes, the contacted surface is also large, more atomized water vapor can be adsorbed, and finally the atomized water vapor is gathered into water drops to be discharged through the drain valve, so that the water vapor is separated from the carbon dioxide gas, and the separated carbon dioxide gas enters the condenser 3 through the exhaust pipeline 9.

The heat exchange tube 6 is provided with an upper connector and a lower connector, the upper connector and the lower connector are communicated with the shell side of the condenser 3, so that the heat exchange tube 6 is communicated with a storage chamber of cooling liquid in the condenser 3, namely, the cooling liquid in the heat exchange tube 6 can flow into the storage chamber of the cooling liquid in the condenser 3, the cooling liquid in the condenser 3 can also flow into the heat exchange tube 6, when the cooling liquid is replaced, the cooling liquid in the gas-liquid separator 5 can flow out after flowing into the condenser 3 only by opening a cooling liquid outlet at the bottom end of the condenser 3, and the replacement of the cooling liquid in the gas-liquid separator 5 is facilitated.
