Tower absorption membrane contactor for CO2 capture

The invention relates to the technical field of membrane contactors, in particular to a tower absorption membrane contactor for CO2 capture, which comprises a box body, the top of the box body is communicated with a filter ring, the inner bottom wall of the filter ring is fixedly provided with a buffer spring, the top of the buffer spring is fixedly provided with a filter sheet, and the top of the filter sheet is fixedly provided with a vertical pipe. A breather pipe is connected into a port needing to be connected, then gas enters a box body, then the gas passes through the lower portion of a partition plate, passes through a first sealing plate and is filtered through a filter to enter a second connecting pipe, and then a reciprocating spring conducts reset operation on a second sealing plate. According to the contactor provided by the utility model, the air is filtered by the filter ring, and in the filtering process, the air impacts the filter ring, so that subsequent cleaning and absorption operations on
