Abstract

The invention provides an internal circulation pressure swing adsorption hydrogen purifier. The internal circulation pressure swing adsorption hydrogen purifier mainly consists of a first adsorption purifying cylinder, a second adsorption purifying cylinder, a gas-water separator, a piston cylinder, a connecting rod driver, a push and pull connecting rod, a throttle valve, an electromagnetic intercepting valve, a ventilation one-way valve, a back pressure valve, a back-fire relief valve and the like, wherein the first adsorption purifying cylinder and the second adsorption purifying cylinder are arranged internally side by side and are filled with an adsorbent. A large-flow internal circulation process accompanied by micro discharge is adopted, and gas purification is realized by changinga gas purification process. Compared with an existing purifier, the purity of purified gas is constant, and the consumption of high purity gas for regeneration is only 4 percent of the existing products. The energy consumption is 3.6 percent of the existing products. The defects of the existing traditional equipment are changed: the consumption of high purity hydrogen gas is high, the production amount of waste hydrogen gas is large and the like. By adopting the internal circulation pressure swing adsorption hydrogen purifier, the production amount of the waste hydrogen gas is reduced, and internal circular use of the high purity hydrogen gas is realized.

Description

technical field [0001] The invention belongs to the technical field of gas purification, in particular to an internal circulation pressure swing adsorption hydrogen purifier used for pure water electrolysis to produce hydrogen. Background technique [0002] With the increasingly serious air pollution problem and the continuous improvement of gas purity requirements, as a gas purifier that can absorb, decompose or transform gas pollutants, and effectively improve the cleanliness of the gas, it has become a "hot appliance" at present. It has become a popular electrical appliance, which shows that the gas purification equipment has developed rapidly and has a good prospect in recent years. [0003] As a clean and efficient energy carrier, hydrogen energy has high hopes. Hydrogen is widely used in chemical industry, electronics, scientific research, energy, special sintering, inspection and quarantine, generator cooling and other fields; electrolysis of pure water hydrogen prod...
