Title: Gas separating laminated membrane
Inventor: SAWADA TASUKE
IPC: B32B27/00
Filed: 1989-06-30
Abstract: PURPOSE:To obtain a membrane stable even at a high temp. and a humidity and having superior oxygen selectivity and oxygen permeability by laminating a membrane of polymethylpentene mixed with polysiloxane on a porous support membrane and further laminating a polysiloxane membrane. CONSTITUTION:When polysiloxane is added to polymethylpentene by 5-50wt.%, a membrane having about >=3.0 oxygen selection factor and superior oxygen permeability is obtd. In the case of >=50wt.% polysiloxane, a homogeneous membrane is not formed by spreading on the surface of water and the oxygen selection factor of a formed membrane is reduced. In the case of <5wt.% polysiloxane, laminating cannot be carried out only by contact with a porous support. Since the flow rate of gas permeating a gas separating membrane rich in siloxane structure lowers hardly, the lowering of the flow rate of gas can be inhibited by laminating a polysiloxane membrane as a protective coat. A membrane having a high oxygen selection factor and high oxygen permeability and maintaining superior characteristics when allowed to stand at high temp. and humidity is obtd.

SOLUTION: When an evaporator 22 is heated by a burner 25, a working liquid 12 is heated, evaporated and introduced into a condenser 1 via a pipe 7 to push the working liquid 12 within a cylinder 2 downward. Volume of a heating space 6 increases to exceed a heat insulation part 24, and, when introduced to a condensation space 5, the working liquid in gas phase is condensed. By this liquefaction, high temperature of the working liquid 12 in gas phase raises temperature of the liquid 12 in a liquid tank 4 and a condensation space 15. And, the working liquid 12 in the cylinder 2 and a coil device 4 is heated. That is, high temperature of the liquid 12 is dissipated to the working liquid 12 and temperature of the working liquid 12 is raised and the working liquid 12 flows into the coil device 4.  Thus, temperature around each heat radiating part 18 heated by the working liquid 12 is diffused into a room by rotation of a motor driven fan 21 for heating.
