<p>PURPOSE:To make it possible to clean the inside of a pipe and the surroundings of the pipe by providing a pipe for use in sea water with ventilating/deodorizing facilities. CONSTITUTION:Putrefied gas inside a pipe 2 is introduced into a deodorizing tower 12 through a deodorizing tower inlet valve 11 by the operation of a suction blower 10. The gas discharged from the deodorizing tower 12 is returned to inside of a sea water pipe 21 through a gas circulating line 18 but then the concentration of putrefied gas has been measured by a gas analyzer 17 and the constitution is so arranged that valves 11, 13, 14, 15 and a manhole 8 may be opened to discharge the gas inside the pipe into the air when the concentration is lowered. Consequently, the putrefied gas is not directly discharged to the air and further the putrefied gas inside the pipe is deodorized, therefore the surroundings inside and outside the pipe can be cleaned.</p> |
