Embodiment Construction

[0020] The gas supply device shown in this embodiment is provided with two pressure regulators 21, 31 in series as a decompression unit for reducing the pressure of the gas supplied from the high-pressure gas container 11. The high-pressure gas container 11 is a compressed gas supply source filled with compressed gas at a predetermined high pressure; and it is formed so that the high-pressure gas is decompressed at a predetermined decompression degree by the first pressure regulator 21 that uses the gas flow to the upstream side. As the medium-pressure gas, the medium-pressure gas is decompressed at a predetermined decompression degree by the second pressure regulator 31 on the downstream side, and the low-pressure gas at the pressure required by the supply destination is supplied. For example, in the case of depressurizing and supplying compressed gas having a filling pressure of 9 MPa (absolute pressure, hereinafter the same) to near atmospheric pressure, after depressurizing...

Abstract

Provided is a gas supply system in which the pressure of a compressed gas can be reduced in a stable state and the resulting gas can be supplied, as well as the system has an excellent economy and safety, wherein the pressure of a gas supplied from a source of a compressed gas (high-pressure gas container 11) is reduced by a pressure reducing means (pressure regulator 21, 31) and the resulting gas is supplied, wherein, on the upstream side, in the gas flow direction, of the pressure reducing means, a heat exchanger 22, 32 which heats the gas by heat exchange of a gas introduced to the pressure reducing means and warm water supplied from a warm water source (warm water circulation unit 15) is provided, as well as, in the pressure reducing means, a warm water flow channel 53 for heating the pressure reducing means by a part of the warm water is provided.

Description

technical field [0001] The present invention relates to a gas supply device. Specifically, it relates to a gas supply device that decompresses and supplies compressed gas. Background technique [0002] When supplying compressed gas from a 47-liter container or a large container, the compressed gas is decompressed to a specified pressure by a decompression unit such as a pressure regulator, a pressure reducing valve, or a control valve. At this time, since the temperature of the gas decompressed by the decompression unit is lowered due to adiabatic expansion and the Joule-Thomson effect, dew condensation and frost may occur on the outer surface of the decompression unit, making it difficult to monitor the pressure of the gas. adjustment. Therefore, there is a process of suppressing a decrease in the temperature of the decompressed gas by heating the upstream side piping (primary side piping) of the decompression unit or the heating and decompression unit (for example, refer ...
