Title:
APPARATUS AND METHOD FOR CARRYING ARTICLE BY GASES FORMED MAINLY OF STEAM
Document Type and Number:
WIPO Patent Application WO/2005/012148
Kind Code:
A1
Abstract:
An apparatus for carrying articles by gases formed mainly of steam, wherein when mixed fluid flows down inside a carrying tube (20), a forced open/close valve (24) is quickly closed to cause a water hammering in the carrying tube (20) so as to open a pressure relief valve (22) to relieve a pressure on the upstream side of the forced open/close valve (24) into a compression /decompression tank (18) and to cause a plug flow in the carrying tube (20) on the downstream side of the forced open/close valve (24), a first open/close valve (27) is opened and steam and pressurized gas are fed into the compression/decompression tank (18) through a first feed pipe (30) and a second feed pipe (32) to send the mixed fluid in the compression/decompression tank (18) into the carrying tube (20) through a first communication pipe (26) so as to lower the level of water in the compression/decompression tank (18), the first open/close valve (27) is closed and a second open/close valve (29) is opened to introduce steam into the carrying tube (20) through a second communication pipe (28), and the second open/close valve (29) is closed and the forced open/close valve (24) is quickly opened to flow the mixed fluid to the downstream side so as to condense the steam in the carrying tube (20) to bring the pressure inside the carrying tube (20) into a negative pressure, whereby since the water level of the mixed flow in the carrying tube (20) can be recovered, the articles can be carried to a far distance.
