DEVICE FOR FLUID DEGASSING Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: device has cylindric housing, tangential inlet branch pipe, guiding baffle secured to the branch pipe and defining screw surface, shell with branch pipe for evacuation mounted at the top part of the device and having chamfered bottom face and outlet branch pipe mounted at its bottom part, shell mounted at the bottom part of the device and whose top face is projected into the top shell, deflector mounted above the top part of the bottom shell, pipe coil with cooler interposed between the housing and bottom shell, branch pipe for supplying vapor, and non-reverse through valve mounted at the top part of the housing. When the pump feds the gas- liquid flow through the inlet branch pipe to the housing the screw guide baffle directs the flow from the top to the bottom. The vacuum pump creates a pressure difference between the top part of the shell and bottom part of the housing. When vapor is supplied into the housing through the branch pipe, which is mounted at its top part, the vapor bubbles through the gas-liquid mixture bed. In so doing, the coolant in the pipe coil cools the liquid. EFFECT: enhanced efficiency. 3 cl, 1 dwg
