A dry kiln tail gas waste heat recovery and material preheating system

Abstract

The utility model discloses a kind of drying kiln tail gas waste heat recovery and material preheating system, including material storage tank, the inner chamber of the material storage tank is fixedly connected with multiple equidistant distribution heat exchange plate, and the periphery of material storage tank bottom is fixedly connected with spring. The utility model preheats the material to be preheated from feed inlet to material storage tank, when tail gas enters heat exchange plate from air inlet pipe, heat exchange treatment with material can be carried out, so that material preheating treatment can be carried out, and in this process, third motor can be controlled to rotate, under the cooperation of first gear, second gear can be driven to rotate, and under the cooperation of spring, sleeve and slide bar, oscillating plate can be made to knock material storage tank, so that material vibration treatment can be carried out, control hydraulic rod telescoping, under the cooperation of adjusting rod, the position of material storage tank can be adjusted, so that material shaking treatment can be carried out, further improve the heat exchange efficiency of material and tail gas.
