[0004] (1) There are moving parts, and its sealing parts need regular maintenance;
[0005] (2) There is greater noise and vibration;
[0006] (3) Pollution discharge exists;
[0007] (4) The purity of hydrogen will be reduced under the action of oil vapor;
[0008] (5) High energy consumption and high operating costs;
[0009] (6) Large footprint
[0010] In addition, sometimes the concentrated hydrogen supply of pipelines may have some impurity components in hydrogen that are higher than the standard content, which will affect the test results of the back-end hydrogen analysis instrument, and there is a need for hydrogen purification

Abstract
The invention relates to a hydrogen supply device for analytical instruments, belonging to the field of hydrogen supply. The device includes air intake coil, cabinet, filter, check valve, pressure gauge, ball valve, safety valve, hydrogen booster tank, thermocouple, thermostat, silicone heating jacket, insulation jacket, aluminum silicate insulation cotton balls , hydrogen storage tank, gas outlet coil and other components. It can purify hydrogen and provide hydrogen at any output pressure between 1‑20MPa. The hydrogen supply device has no vibration and noise, simple structure, easy to implement, simple, convenient and safe to operate, and occupies a small space. It can use the existing low-pressure pipeline hydrogen in the laboratory as the gas source without any liquid for heating or cooling. medium, there is no risk of leakage, and the intermediate gas path can be vacuumed during use, which will not cause a lot of gas waste.
Description
technical field [0001] The invention relates to the field of hydrogen supply, in particular to a hydrogen supply device for analytical instruments. Background technique [0002] For laboratories, the decentralized cylinder gas supply method in the past is not conducive to safe and efficient management. The centralized gas supply system, also known as the central gas supply system, is a gas supply method that is more and more widely used by people. However, the pressure of the centralized gas supply system is generally not too high, because the gas pressure required by most instruments is not too high, and in many cases the pressure <1MPa is enough for use. In addition, for centralized gas supply, due to the longer gas pipeline, low-pressure gas supply is beneficial to reduce leakage and is conducive to safety management. [0003] However, some laboratories occasionally need to purchase some instruments and equipment that use high-pressure hydrogen for experiments, such ...
