Document Type and Number:
WIPO Patent Application WO/2021/208504
Kind Code:
A1
Abstract:
Disclosed is a fuel gas double-wall pipe (1) drainage system, comprising a fuel gas double-wall pipe (1), discharge pipes (2) and a discharge tank (3). The fuel gas double-wall pipe (1) comprises an outer pipe (11) and an inner pipe (12); a discharge pipe (2) is connected at the lowest point of each pipe body bent part of the outer pipe (11); combustible gas detection devices (4) are arranged on the connecting pipe sections between the outer pipe (11) and the discharge pipes (2); water outlets of the discharge pipes (2) are connected to a water inlet (31) of the discharge tank (3); a first stop valve (32) for controlling the opening or closing of the water inlet (31) of the discharge tank (3) is arranged at the water inlet (31) of the discharge tank (3) in a cooperative manner; a discharge port (33) is provided in the bottom of the discharge tank (3); and a second stop valve (34) for controlling the discharge port (33) to be opened or closed is arranged at the discharge port (33) in a cooperative manner. The fuel gas double-wall pipe (1) drainage system can solve the technical problems that condensed water is directly discharged to a cabin, and that when the space between the inner pipe and the outer pipe of the double-wall pipe (1) is damaged, fuel gas may possibly be discharged into the cabin, such that a fire hazard is caused.
