Foam cooling device

The utility model relates to the technical field of gasoline production, in particular to a foam cooling device which comprises a container, a support fixedly installed at the bottom of the container, an air inlet pipe communicated and fixedly installed at the bottom of the container, an annular seat fixedly installed in the container, an inner groove body arranged in the container, and foam filled in the inner groove body. A plurality of evenly-distributed air holes are formed in the bottom of the inner tank body, a driving mechanism is installed on the container, high-temperature gas is introduced into the container through the air inlet pipe, the gas is dispersed in the container in the rising process and evenly distributed, meanwhile, the gas enters the inner tank body through the multiple air holes, and therefore the gas makes contact with foam more evenly, and the foam can be more evenly formed. And the driving mechanism drives the annular connecting seat to rotate slowly, so that the position of the fo
