This invention discloses a high-efficiency carbon dioxide capture device and method for the petrochemical industry, relating to the field of flue gas treatment technology in the petrochemical industry. It includes a spray tower and a spray stage adjustment component. The spray tower has a built-in spray stage adjustment component, which includes a primary spray sleeve embedded inside. A corrugated pipe is connected to the top input port of the primary spray sleeve, and the corrugated pipe is connected to the outlet end of a spray pump. The spray pump is fixedly installed on the outer top of the spray tower. This application employs a nested primary and secondary spray sleeve structure, achieving flow channel communication through the insertion of sockets and spigots. Combined with the rigid fixation of the core tube to the primary spray sleeve, synchronous linkage switching of the spray stages is achieved. This eliminates the need for complex valve control mechanisms, resulting in a simple structure, reliable linkage, reduced manufacturing and maintenance costs, and suitability for the continuous operation requirements of the petrochemical industry.
