Problems solved by technology

The existing hydrogen treatment and purification process has low working efficiency and poor purification effect
When hydrogen is filtered, a filter or filter holder is usually used to achieve hydrogen filtration. The filter or filter holder is prone to clogging after a long period of use. The existing filter or filter holder is usually fixed. Therefore, it is very inconvenient to disassemble and clean up, increase the labor burden, and increase the cost of cleaning
When water-absorbing materials (such as: sponge layer, etc.) are used to realize hydrogen water filtration treatment, the water-absorbing materials contain a large amount of water after long-term use, and if the water is not removed in time, the water-absorbing properties and air permeability of the water-absorbing materials will be greatly reduced, thereby Make hydrogen water filtration treatment affected

Abstract

The invention discloses a hydrogen treatment and purification process and its device. The purification process comprises the following steps: step 1: import into a condensation tank and treat at low temperature; step 2: import into a hydrogen storage alloy tank, first perform low-temperature and high-pressure treatment, and then perform high-temperature and low-pressure treatment Processing; step 3: introducing into the adsorption equipment, and adjusting the air pressure; step 4: purifying hydrogen. The purifying device includes a purifying box, in which a filtering assembly, a water filtering assembly and an activated carbon adsorption layer are arranged in the said purifying box, and the said filtering assembly includes a first positioning frame, a screw mandrel, a cylindrical transmission frame, a lifting seat, a filter frame and A driving motor, the water filtering assembly includes a second positioning frame, a rotating shaft, a belt, a water-absorbing layer and an extruding shaft. This purification process improves the efficiency and effect of hydrogen purification. The filter frame in the hydrogen purification device realizes convenient installation, disassembly and cleaning, reduces labor burden, reduces cleaning costs, realizes timely removal of water in water-absorbing materials, and ensures the water-absorbing properties of water-absorbing materials. breathability.

Description

technical field [0001] The invention relates to the field of hydrogen purification, in particular to a purification device for a hydrogen treatment and purification process. Background technique [0002] Hydrogen is an environmentally friendly and clean energy source. The produced hydrogen usually contains moisture, tiny particles, etc., and the hydrogen needs to be purified. The existing hydrogen treatment and purification process has low work efficiency and poor purification effect. When hydrogen is filtered, a filter or filter holder is usually used to achieve hydrogen filtration. The filter or filter holder is prone to clogging after a long period of use. The existing filter or filter holder is usually fixed. Thereby it is very inconvenient to disassemble and clean up, increase the labor burden and increase the cleaning cost. When water-absorbing materials (such as: sponge layer, etc.) are used to realize hydrogen water filtration treatment, the water-absorbing materia...
