Purging and purifying system inside hydrogen generator

Abstract

The invention discloses a purging and purifying system inside a hydrogen generator. The purging and purifying system comprises the hydrogen generator, a gas-water separator, a liquid seal and a hydrogen purifier which are connected through pipelines. The hydrogen generator is connected with the gas-water separator through a first one-way valve, and the gas-water separator is connected with the liquid seal through a multi-way connector. The hydrogen purifier comprises at least two sets of purifier cylinders, and the lower portions of all the purifier cylinders are connected through pipelines toform a first loop. Two sets of solenoid valves are arranged on the positions, between every two adjacent sets of purifier cylinders, of the first loop, and the lower portions of all the purifier cylinders are further connected with the first loop in parallel to be provided with a second loop. Solenoid valves with the same number as those of the first loop are arranged on the second loop, and theupper portions of every two adjacent sets of purifier cylinders are further connected with pressure adjusting valves. The upper portions of all the purifier cylinders are connected with outlet pipelines correspondingly, and the multi-way connector is further connected between every two adjacent sets of solenoid valves of the first loop through pipelines. The liquid seal is connected between everytwo adjacent sets of solenoid valves of the second loop through pipelines.

Description

technical field [0001] The invention relates to a hydrogen generator, in particular to a purging and purification system inside the hydrogen generator. Background technique [0002] Traditional large-scale hydrogen generators usually use external inert gas to discharge internal residual gas, and then separate the inert gas into hydrogen, which not only increases the tedious process of external gas source, but also increases the separation device of inert gas, making the whole process complicated and unnecessary. It is beneficial to safe production and increases risk factors. This new technology does not need an external gas source, and the internal gas is evacuated through the self-generated gas source, which greatly simplifies the process and operation steps, improves the safety of operation, and reduces the production input cost. [0003] As the most efficient and clean energy source, hydrogen has become a research hotspot in various countries. Hydrogen production by elec...

AI Technical Summary

Problems solved by technology

After the external gas source is connected, nitrogen removal process steps need to be added, which makes the process pipeline in the hydrogen production device complex and cannot realize automatic control

It takes a long time for the traditional hydrogen production device to turn on the hydrogen production, and it takes several hours. It cannot achieve the effect of rapid hydrogen production when the hydrogen production is turned on. Therefore, an external gas source must be connected to realize the purging and replacement of the internal air.
