Problems solved by technology

Commonly used analyzer probes have certain requirements on pressure and flow rate. Excessive pressure and flow rate can easily damage the analyzer probe, so it is necessary to limit the analysis pressure.
Commonly used analytical instruments have relatively high precision. Most probes use alka

Abstract

The invention provides a multi-functional pretreatment device for water-electrolysis hydrogen production analyzer. The device comprises water-electrolysis hydrogen production equipment, the water-electrolysis hydrogen production equipment is connected with a pressure reducer, the pressure reducer is connected with a drier, the drier is connected with an entrance end of a two-position three-way valve, an exit end of the two-position three-way valve is externally connected to a manual sampling analysis pipeline and the other exit end of the two-position three-way valve is connected to a micrometering valve, the micrometering valve is connected to a first entrance end of a two-position four-way valve, a first exit end of the two-position four-way valve is connected with an analysis meter, the analysis meter is connected to a second entrance end of the two-position four-way valve, a second exit end of the two-position four-way valve is connected with a gas flow meter, the entrance end of the drier and the exit end of the gas flow meter are provided with pressure releasing pipelines, and the pressure releasing pipelines are provided with miniature safety valves. By the switching of a valve gate of the two-position four-way valve, damage to a probe of the analysis meter due to long term operation in the air and disqualified gas can be avoided, so that the analysis meter is prevented from damage, and the maintenance cost is saved.

Description

technical field [0001] The invention relates to a water electrolysis hydrogen production treatment device, in particular to a water electrolysis hydrogen production analyzer multifunctional pretreatment device. Background technique [0002] The scope of application of hydrogen production by water electrolysis is relatively wide, and the gases produced are hydrogen and oxygen. The purity of hydrogen is generally 99.3%-99.8%, and the purity of oxygen is generally 99.2%-99.5%. In order to determine the quality of the gas, it is necessary to analyze the generated gas through an online analysis instrument in real time. At the same time, the purity of the gas is also an important indicator for judging the quality of the core component of water electrolysis hydrogen production - the electrolyzer. Since water electrolysis is carried out in lye, the gas produced contains a small amount of lye and water. These two impurities will cause great damage to the analyzer probe and must be r...
