Full-temperature-range pressure-swing adsorption method for removing hydrogen sulfide from hydrogen rich gas source

The invention discloses a full-temperature-range pressure-swing adsorption method for removing hydrogen sulfide from a hydrogen rich gas source and relates to the technical field of gas desulfurization and purification. According to the technical scheme of the invention, after the full-temperature-range pressure-swing adsorption and concentration process, most of H2S in hydrogen rich gas are removed, and then remaining H2S in hydrogen rich gas can be continuously and deeply removed through selecting the pressure-swing adsorption method or the one-time adsorption method. After that, the H2S-enriched desorbed gas is directly fed into a desulfurization and sulfur-production device, and the gas amount of the above gas is reduced by 80% compared with the gas amount of raw materials. Meanwhile, the circulation volume of the desulfurizing liquid is reduced, and the energy consumption of a machine pump is reduced at the same time. The desulfurization and sulfur-production device can adopt the sodium carbonate desulfurizing and sulfur-producing process or the Claus process, and H2S in the H2S-enriched desorbed gas is removed to be about 100 ppm. Elemental sulfur foams produced during the desulfurizing process are made into sulphur by means of a sulfur retrieving device.
