Title:
APPARATUS FOR RAPIDLY REPLACING GAS IN HYDROGEN STORAGE TANK
Document Type and Number:
WIPO Patent Application WO/2024/016770
Kind Code:
A1
Abstract:
An apparatus for rapidly replacing gas in a hydrogen storage tank, comprising a hydrogen storage tank (10), a motor (21), a replacement gas input pipe (30), and two measurement pipes (40). An inner magnetic ring (11) is slidably connected in the hydrogen storage tank (10); a diaphragm (111) is fixedly connected to the inner ring of the inner magnetic ring (11); an outer magnetic ring (12) is slidably connected to the outer ring of the hydrogen storage tank (10); a rack (23) is fixedly connected to the outer wall of the outer magnetic ring (12); a driving gear (22) is fixedly mounted at the output end of the motor (21) and engaged with the rack (23); the upper end and the lower end of the hydrogen storage tank (10) are both communicated with output pipes (13); discharge valves (134) are provided on pipe sections of the output pipes (13); the pipe sections of the output pipes (13) located between the discharge valves (134) and the hydrogen storage tank (10) are communicated with pressure sensors (133); the output end of the replacement gas input pipe (30) is communicated with two input branch pipes (31); replacement gas inlet valves (32) are provided on pipe sections of the input branch pipes (31); and the input branch pipe (31) located on an upper portion is communicated with a hydrogen input pipe (33). The apparatus solves the problems in the prior art of low internal gas replacement speed and the like of the hydrogen storage tank.
