Simple hydrogen single-stage pressurized purifying filling system and using method thereof

Abstract

The invention relates to the field of hydrogen recovery and filling, in particular to a simple hydrogen single-stage pressurized purifying filling system and a using method thereof. The simple hydrogen single-stage pressurized purifying filling system comprises sold low-pressure hydrogen cylinders, a first ball valve, a first pressure sensor, a first check valve, a high-pressure container, a safety valve, a first temperature measuring sensor, a second temperature measuring sensor, spherical composite hydrogen storage materials, an electric heating bar, a filter, a second pressure sensor, a second check valve, a second ball valve, sold low-pressure hydrogen cylinders, a circulating cold water system, an electromagnetic valve, a spraying device, a tray, a controlling system, a running-watertap and the like. The working procedure is mainly divided into the two processes of temperature reducing hydrogen-sucking and temperature rising hydrogen-releasing. The simple hydrogen single-stage pressurized purifying filling system has the advantages that the universality is high, safety and high efficiency are achieved, operation is simple and convenient, area occupied is small, adjusting is convenient, hydrogen can be purified while pressurizing, no operating parts are required, no abrasion are achieved, and noise is low.

Description

technical field [0001] The invention relates to the field of hydrogen recovery and filling, in particular to a simple hydrogen single-stage pressurized and purified filling system and its use method. Background technique [0002] Hydrogen is widely used in industrial and agricultural production processes. At present, the pure hydrogen (99.99% volume concentration) and high-purity hydrogen (99.999% volume concentration) widely used in the market are supplied by steel cylinders with a full bottle pressure of about 13MPa and a volume of 40L. In the process of using these cylinders of hydrogen, in order to ensure the safety of refilling, the national standard (GB 4962-2008, hydrogen use safety technical regulations) stipulates that the gas in the hydrogen cylinder must not be exhausted, and at least 0.15MPa should be kept in the cylinder. (absolute pressure) above the pressure to prevent air from entering the cylinder. However, in practice, because the pressure does not reach t...
