LNG VAPORIZER SEAWATER FLOWMETER WASHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an LNG vaporizer seawater flowmeter washing device capable of decreasing the possibility of adhesion of marine organisms and the like onto a connecting path of a seawater flowmeter, ensuring the performance of a removal work flowmeter, and lessening manual washing work.;SOLUTION: Wash water injection pipes (22a, 22b) are connected to one end of a connecting header pipe (13a) and that of a connecting header pipe (13b) of a seawater flowmeter (10), which measures a flow volume of seawater flowing through a seawater pipe (2) connected to a vaporizer (1), via injection nozzles (21a, 21b), respectively, and wash water discharge pipes (25a, 25b) are connected to the other ends of the connecting header pipes (13a, 13b), respectively. When the vaporizer (1) stops, header pipe source valves (12, 12b) are closed and wash water is injected into the connecting header pipes (13, 13b) from the respective injection nozzles (21, 2b), thereby removing deposits on the connecting header pipes (13a, 13b) as well as connecting pipes (14a, 14b).;COPYRIGHT: (C)2015,JPO&INPIT
