JPS6127397A - Gasifying device for liquidized gas - Google Patents

Abstract

PURPOSE:To gasify stably through the heat at the outside of container by extending a portion of member having high heat conductivity for holding a gas flow limiting member provided at the opening of liquidized gas container to the outside of the container. CONSTITUTION:A holding member 12 having high heat conductivity where a gas flow limiting member or a porous film 11 is extending to the outside of the container 8 and a compression member 13 made of synthetic resin are held at the opening 10 of a liquidized gas container 8. A liquid lead pipe 14 composed of a bundle of fibers or thin tubes is fixed to said film 11, and extending to the interior of the container 8. Since the heat necessary for gasification is fed through said member 12 by the air at the outside of the container 8, stable gasification is achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to equipment that uses liquefied gas as fuel, particularly to a device for vaporizing liquefied gas for borrowed equipment.

Conventional Structure and Problems In general, a liquefied gas vaporization device, as shown in FIG. 2, is a gas flow rate restricting member formed by a holder 4 and a compression cylinder 6 in an opening 3 of a container 2 storing a liquefied gas 1. A porous membrane 6 is provided,
The other end of the liquid guide 7 provided in contact with the porous membrane 6 was immersed in the liquefied gas 1.

The mechanism of vaporization is that the liquefied gas is applied to the porous membrane 6 from the liquid guide 7, and the pressure is reduced from the high pressure inside the container 2 to the outside atmospheric pressure, and that the liquefied gas is applied to the porous membrane 6 from the holder 4 and compression cylinder 6 provided around it. It vaporizes due to the heat applied.

In this way, when gas vaporizes, it is greatly influenced by the amount of heat given by surrounding materials, and the balance of heat exchange is determined by the amount of vaporization and the heat transfer coefficient of surrounding materials. Particularly when the container 2 is made of a molded article of synthetic resin or the like, there is a problem in that the heat transfer of the container 2 is poor and the temperature around the porous membrane 6 drops extremely, causing poor vaporization.

OBJECTS OF THE INVENTION The present invention takes into account the above-mentioned conventional problems and aims to provide a vaporizer with a stable vaporization amount.

Structure of the Invention In order to achieve the above-mentioned object, the liquefied gas vaporization device of the present invention extends a part of the holding cylinder holding the gas flow rate limiting member for vaporizing the liquefied gas so as to be in direct contact with the outside air. The heat required for vaporization is obtained from the outside air.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the figure, reference numeral 8 denotes a container for storing liquefied gas 9, and a porous membrane 11 serving as a gas flow rate restricting member extends to the outside of the container 8 at an opening 10 of the container 8, and a holder 12 with a high heat transfer coefficient. , is held by a compressed weight 3 made of synthetic resin.

A liquid guide pipe 14 made of bundles of fibers and thin tubes is still attached to the porous membrane 11, and this waveguide 14 extends to the inside of the container 8.

According to the above configuration, the liquefied gas 9 is supplied to the porous membrane 11 using the liquid guide pipe 14 as a flow path, and is depressurized here.

vaporized.

The heat required for vaporization is efficiently supplied to the air outside the container 8 through this holder 12. Furthermore, if heat absorbing fins 16 or the like are attached to the holder 12, the heat necessary for vaporization can be supplied sufficiently even if the outside temperature is low to a certain extent, so that the heat can be transferred extremely efficiently as a whole. This allows for stable vaporization at all times.

Effects of the Invention As is clear from the description of the above embodiments, according to the liquefied gas vaporization apparatus of the present invention, heat from outside the container is supplied to the vicinity of the gas flow rate restricting member, so that vaporization is always carried out in a stable state. become.
