Ancient building black brick firing kiln tail gas waste heat recycling system

The invention discloses an ancient building black brick firing kiln tail gas waste heat recycling system which comprises a kiln body, a brick placing frame and a coal frame. The coal frame is located at the bottom of an inner cavity of the kiln body, the brick placing frame is located in the kiln body, an air pump is fixedly connected to the right side of the top of the kiln body, an air suction opening of the air pump communicates with a desulfurizer, the bottom of the desulfurizer is fixedly connected with the top of the kiln body, the back of the desulfurizer communicates with a first pipeline, and the bottom of the first pipeline penetrates through the kiln body and extends into the kiln body. The invention relates to the technical field of gas waste heat utilization. According to the ancient building black brick firing kiln tail gas waste heat recycling system, tail gas generated by a brick kiln is circulated through the mechanisms, after the tail gas returns into the kiln, coal can be combusted and drie
