Embodiment 1

[0049] This embodiment is a preferred solution. This embodiment adopts the pressure swing adsorption purifier of the multi-tank parallel connection and simultaneous air intake mode of the above invention. Taking double tank parallel connection and three sets of purification tanks as an example, and the electromagnetic valve, pressure Sensors and other components use image 3 The way it belongs is placed upside down on the lower side of the second connecting body. Using a single layer of 13X molecular sieve as the adsorbent, the total volume of the designed pressure swing adsorption purifier is 50L, the gas component introduced is a hydrogen-rich gas with a hydrogen volume content of about 75%, and the amount of hydrogen-rich gas introduced is 150SLP. When the hydrogen purity is 99.999%, the pure hydrogen output is 84SLP, the accumulated time is not less than 4000 hours, and the hydrogen purification efficiency is greater than 80%. After calculation, to produce 1 cubic meter o...

Abstract

The invention provides an efficient multi-tank intake type pressure swing adsorption purifier, which comprises a plurality of purification tank groups, wherein each purification tank group consists of two or more purification tanks which are connected in parallel or in series, first connecting bodies for connecting the lower ends of the purification tanks and second connecting bodies for connecting the upper ends of the purification tanks. The multi-tank intake type pressure swing adsorption purifier further comprises a product gas buffer tank and an exhaust gas treatment end. An intake passage, an intake valve, a cleaning passage, a cleaning valve, an exhaust gas discharging passage, an exhaust gas discharging valve and a purified gas leading-out passage are shared by the purification tanks in each purification tank group, and each purification tank in each purification tank group is provided with a purified gas outlet check valve. According to the multi-tank intake type pressure swing adsorption purifier, the purification efficiency of the pressure swing adsorption purifier is effectively improved, and the raw material cost is reduced, and manual maintenance and transportation cost is also reduced; electromagnetic valves and pressure sensors on the connecting bodies on the purification tanks of the pressure swing adsorption purifier are arranged upside down at the lower sides, so that convenience is brought for the packaging and transportation of equipment.

Description

technical field [0001] The invention relates to a gas purification device utilizing the principle of pressure swing adsorption, in particular to an efficient multi-tank intake type pressure swing adsorption purifier. Background technique [0002] PSA gas purification technology is a technology that uses adsorbents to absorb impurity components at high pressure and desorb impurity components at low pressure to purify the gas. [0003] Since the example of the PSA system was disclosed in the patent US3430418, the patents US3564816 and US3986849 successively carried out optimization research on the basis of the former, and then more units conducted research and improvement on the PSA purification process, equalization steps, and use of valve control. , but there are still complexities in the structure and PSA cycle, and the purifiers are all biased towards large-scale. In view of the above problems, a small and portable pressure swing adsorption purifier was designed, which wa...
