Title:
SYSTEM AND METHOD FOR MONITORING AIR LEAKAGE OF NEGATIVE PRESSURE SYSTEM BY MEANS OF HYDROPHOBIC PIPELINE
Document Type and Number:
WIPO Patent Application WO/2023/201892
Kind Code:
A1
Abstract:
A system for monitoring air leakage of a negative pressure system by means of a hydrophobic pipeline. The system comprises a sampling tube (1), a dissolved oxygen detection tank (2), a vacuumizing main pipe (3) and a gas analyzer (4), wherein one end of the sampling tube (1) is connected to the hydrophobic pipeline of the negative pressure system, and the other end of the sampling tube is connected to a condensation separation tank (5), so that a sample entering from the negative pressure system is condensed and separated by means of the condensation separation tank (5); a condensate level meter (6) is provided in the condensation separation tank (5); the dissolved oxygen detection tank (2) is connected to a dissolved oxygen detector (7) and the condensation separation tank (5), so that the oxygen content in water separated in the condensation separation tank (5) is detected by means of the dissolved oxygen detector (7); and the dissolved oxygen detection tank (2) is connected to the vacuumizing main pipe (3), the vacuumizing main pipe (3) is connected to a vacuum pump, the gas analyzer (4) is connected to the condensation separation tank (5) and the vacuumizing main pipe (3), and a dryer (8) is provided between the gas analyzer (4) and the condensation separation tank (5).
