Separation rotary drum in vacuum pressure swing adsorption separator

Abstract

A separation rotary drum in a vacuum pressure swing adsorption separator comprises an air inlet zone at the left end, a middle molecular sieve zone and an oxygen-rich collection zone at the right end. The separation rotary drum is characterized in that the air inlet zone comprises an air inlet pipe, a blowback air outlet pipe, an air inlet cover and an inlet air distribution disc, wherein the inlet air distribution disc is divided into an air inlet sector, an oxygen-rich air suction corresponding sector, a blowback air outlet sector and transition zones formed among the air inlet sector, the oxygen-rich air suction corresponding sector and the blowback air outlet sector. The middle molecular sieve zone comprises a molecular sieve drum, a driven wheel, a motor and a driving wheel, wherein the molecular sieve drum is divided into sectors different in shapes and identical to size with the center axis of the drum serving as the symmetrical axis, each of angles of sectors is omega, and rubber sheets with widths the same as sector separation plates of each sector are arranged at two ends of the sector and are 5mm-30mm long. The oxygen-rich collection zone comprises a nitrogen-rich exhaust pipe, a blowback air inlet pipe, an oxygen-rich air suction pipe, an air outlet cover and an outlet air distribution disc, wherein the outlet air distribution disc is divided into an oxygen-rich air suction sector, a nitrogen-rich air suction sector, a blowback air inlet sector and transition zones formed among the oxygen-rich air suction sector, the nitrogen-rich air suction sector and the blowback air inlet sector.

Description

technical field [0001] The invention relates to a separation drum in a vacuum pressure swing adsorption separator, which is suitable for all vacuum pressure swing adsorption separators and belongs to the technical field of gas separation. Background technique [0002] The vacuum pressure swing adsorption separation technology used to produce oxygen-enriched gas is very mature, but this technology has a disadvantage, that is, it requires multiple reversing valves, and the reversing frequency of the reversing valves is very high, basically Reversing once every ten seconds, for such high-frequency reversing work, no domestic manufacturer can produce high-quality reversing valves, even foreign reversing valves will inevitably have frequent problems, that is to say, the vacuum variable The weak point of the pressure adsorption separation technology is the reversing valve, but there is no vacuum pressure swing adsorption separation technology that can not use the reversing valve ...
