A GAS-LIQUID SEPARATING METHOD AND A GAS-LIQUID SEPARATING TYPE EVAPORATOR

摘要

A gas-liquid separating method and a gas-liquid separating type evaporator, the method includes the following steps: (i) provide a partition device (3) in the upper portion of the evaporated liquid pipe, the partition device (3) divides the evaporated liquid pipe into a superheating section (12) and an evaporating section (13); (ii) a gas-liquid separating pipe (4) is connected to the superheating section (12) near the partition device (3), an evaporated liquid feeding pipe (6) is connected to the evaporating section (13) near the partition device (3), several vapor guiding pipes (5) are respectively provided in the pipe of the evaporating section (13), the vapor guiding pipes (5) are respectively connected with the gas-liquid separating pipe (4); vapor inside the pipe can flow out, and is separated into gas and liquid in the gas-liquid separating pipe (4), then the vapor enters the superheating section (12) and is superheated; the superheated vapor is discharged from a vapor outlet (11); (iii) the residual liquid separated from the gas-liquid separating pipe (4) and the residual liquid in evaporating section (13) are together sent to the evaporated liquid feeding pipe (6) through a return pipe (14), and back to the evaporating and heat-exchanging process of evaporated liquid.
