Sliding plate brick carbonization kiln flue gas cooling device and cooling method

The invention discloses a sliding plate brick carbonization kiln flue gas cooling device and a cooling method, relates to the field of cooling equipment, and aims to solve the problems that a coolingpipeline of a medium-temperature kiln is easy to block to cause dark combustion deformation and bring potential safety hazards, and meanwhile, charge trapping is difficult, the damage rate of a clothbag is increased and the production cost is increased. The cooling device comprises a cooling tower body, and the cooling tower body comprises a box body, a hopper fixedly installed at the lower end of the box body in a sealed mode and a support for supporting the box body and the hopper; the upper portion of the box body is an air distribution layer, a heat exchange layer is arranged below the air distribution layer, a plurality of vertically-arranged heat exchange pipelines are fixedly installed in the heat exchange layer, and a plurality of layers of drainage plates are further arranged inthe heat exchange layer; an
