Embodiment Construction

[0029] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0030] The present invention provides a method and system for compounding hydrogen multi-element inhibitor compound gas, and its specific implementation method is as attached figure 1 As shown, a specific introduction is given below.

[0031] For the method of suppressing the explosion of hydrogen by a single inert gas, the inert gases are selected as helium, nitrogen and carbon dioxide, and they are prepared with hydrogen to form a mixed gas, and then the explosion limit test plan is carried out to determine the suppression effect. In the specific implementation,...

Abstract

The invention relates to a compounding method and system for hydrogen multi-component inhibitor composite gas. The method comprises the following steps of: carrying out cleaning and vacuumizing, checking the connection state, weighing the mass of an empty gas cylinder to be filled, analyzing raw materials in a plurality of raw material gas cylinders, heating and pressurizing the raw material gas cylinders through a first transmission channel and a second transmission channel respectively, filling the gas cylinder to be filled to a required first pressure value and weighing the gas cylinder tobe filled again, repeatedly flushing a pipeline by diluent gas, filling the filled gas cylinder with the diluent gas to a required second pressure value to ensure a stable environment, calculating thecontent of the prepared standard gas based on the total mass of the filled gas cylinder and the mixed gas and the mass of the empty gas cylinder to be filled, uniformly shaking, and the like. Unexpected hydrogen combustion explosion can be effectively prevented, and the safety is improved.

Description

technical field [0001] The invention relates to the field of measurement and detection, in particular to a method and system for compounding hydrogen multiple inhibitor compound gas. Background technique [0002] An aerostat is an aircraft that mainly uses a gas lighter than air to generate static lift to overcome its own gravity. Theoretically, as long as the density of the gas is less than that of the surrounding atmosphere, it can be used as the buoyant gas of the aerostat. Therefore, light gases such as hydrogen, helium, methane, ammonia, natural gas and coal gas can be used as the buoyant gas of the aerostat. Among these buoyant gases, hydrogen has the highest buoyancy efficiency, is cheap and easy to obtain, and has unlimited supply. Due to its high buoyancy efficiency, the volume of airbags required for the same structure and the same loading requirements is the smallest. However, hydrogen is flammable and explosive. Therefore, accidents must be prevented in all aspe...
