Problems solved by technology
[0002] At present, the membrane modules for gas separation at home and abroad are all single-core and single-shell. In the process of use, it is always necessary to connect the process gas to the membrane modules one by one with a busbar. Due to the differences in the recovery rate and pressure difference of each membrane module, Therefore, the connection method of the busbar can easily cause uneven gas distribution, which reduces the efficiency of the membrane group and increases the manufacturing cost of the product; at the same time, in the field of biogas purification technology, multi-stage membrane groups are required to separate the process gas. The method of connecting the membrane modules at all levels will cause heat loss of the process gas, resulting in a decrease in separation efficiency
