After the steam condenses, a layer of condensation liquid film will be formed on the inner wall of the condenser tube, which hinders the subsequent contact between the steam and the cold wall surface, reduces the contact area between the steam and the cold wall surface, and the condensation effect is poor.

The inlet end of the first gas collecting pipe 4 is connected to the main tube 2, and the outlet end of the first gas collecting pipe 4 is connected to the sub-tube 7, and the end of the sub-tube 7 is connected to the drain pipe 5. In order to facilitate the gas to enter the first gas collecting pipe 4, the inlet end of the first gas collecting pipe 4 faces the exhaust end of the first cyclone device 3, that is, the opening of the inlet end of the first gas collecting pipe 4 faces the flow direction of the fluid in the main tube 2.

Due to the large density of the liquid, the centrifugal force it is subjected to is large, and the required centrifugal radius is also large, so that the liquid is mainly collected on the inner wall of the main pipe 2 to form a liquid layer 11, and the liquid is discharged through the drain pipe 5, and most of the gas flow 10 enters the auxiliary pipe 7 through the first gas collecting pipe 4. The gas-liquid separation condensation device of the utility model, by setting the first cyclone device 3 to perform gas-liquid separation on the mixture of gas and liquid droplets, improves the condensation efficiency, and discharges the obtained condensed liquid as soon as possible, greatly improves the dryness of the mixture of gas and liquid droplets, and improves the condensation efficiency of the gas.

The first cyclone device 3 and the second cyclone device 8 can be the same or different, and can be arranged by those skilled in the art according to actual needs.

[0055] The gas-liquid separation condensing device of the utility model has a cyclone device in the condensing tube, and is provided with a gas collecting pipe and a liquid discharge pipe 5.
