AIR INLET PIPE ANTI-DEFLATION SLEEVING DEVICE OF CONDENSER FOR PRODUCTION OF ELECTRONIC GRADE CHLORINE TRIFLUORIDE

WIPO Patent Application WO/2024/000824

A1

Provided is an air inlet pipe anti-deflation sleeving device of a condenser for production of electronic grade chlorine trifluoride. The device comprises a condenser main body (1), wherein a left end of the condenser main body (1) is provided with a water outlet pipe (11), a water inlet pipe (12) is arranged below the water outlet pipe (11), an air guide butt-joint pipe (13) is arranged above the middle of the condenser main body (1), a fixed air inlet pipe (14) is arranged below the air guide butt-joint pipe (13) and located at an upper end of the condenser main body (1) in a penetrating manner, a butt-joint portion is provided on an attached surface of the fixed air inlet pipe (14) and the air guide butt-joint pipe (13), a deflation protection mechanism (2) is arranged above the fixed air inlet pipe (14), a second-stage sealing mechanism (3) is arranged below the deflation protection mechanism (2), and an auxiliary cooling mechanism (4) is provided at an end of the water inlet pipe (12). After each group of sealing cavities (25) are overturned, a relatively sealed space is formed at the butt-joint portion of the fixed air inlet pipe (14) and the air guide butt-joint pipe (13), so that air leakage in a leading-in process can be reduced, thereby reducing the injury to surrounding workers, and improving the safety in use of the device.
