Electrolytic accident chlorine negative pressure water seal device

Abstract

The invention discloses an electrolytic accident chlorine negative pressure water seal device. The electrolytic accident chlorine negative pressure water seal device comprises a chlorine liquid seal tank (1) and a chlorine negative pressure water seal tank (2), wherein an air outlet (3) and a wind breaking opening (4) are formed in the upper part of the chlorine negative pressure water seal tank (2), the air outlet (3) communicates with the inside of the chlorine negative pressure water seal tank (2), and a water seal pipeline (6) is arranged in a water seal gap (5) arranged between the wind breaking opening (4) and the liquid surface of the chlorine negative pressure water seal tank (2); and the wind breaking opening (4) communicates with the inside of the chlorine negative pressure waterseal tank (2) through the water seal pipeline (6), an overflow opening (7) is formed in the side surface of the chlorine negative pressure water seal tank (2), the overflow opening (7) is divided into a branch I (8) and a branch II (10), wherein the branch I (8) communicates with the air outlet (3) through a water outlet pipe I (9), the branch II (10) communicates with the chlorine liquid seal tank (1) through a water outlet pipe II (11), and an outlet (12) is formed in the side surface of the chlorine liquid seal tank (1) and communicates with a chlorine water collecting tank (13).

Description

technical field [0001] The invention relates to a negative pressure water sealing device for chlorine gas in an electrolysis accident. Background technique [0002] The wet chlorine gas from the electrolytic cell enters the chlorine gas scrubber for washing and cooling in the ionic membrane caustic soda plant. The chlorine gas main pipe before entering the tower is equipped with an emergency positive pressure water seal and an emergency negative pressure water seal. If the pressure of the electrolysis system is too high, the chlorine gas sent to the washing tower will break through the positive pressure water seal, and the chlorine gas will be directly discharged into the accidental chlorine device; since the chlorine gas treatment uses a chlorine gas turbine compressor to transport the chlorine gas, the chlorine gas main pipe is set with an accidental negative pressure The water seal can automatically inhale air in an abnormal state to prevent a large negative pressure.

Problems solved by technology

During normal production, abnormal conditions may also be encountered, resulting in excessive negative pressure extracted by the chlorine gas turbine compressor and damage to pipelines and equipment. Therefore, the height of the chlorine gas negative pressure water seal is set at 500 mmH 2 o
