Description

technical field [0001] The invention belongs to the technical field of pulverized coal pyrolysis, and in particular relates to a rotary heat exchange device with arc-shaped cavity for hot semi-coke and pulverized coal and its use method. Background technique [0002] The residual temperature of semi-coke produced by medium and low-temperature pyrolysis of pulverized coal is generally 400-600°C. In order to facilitate the safe storage of semi-coke and recover the sensible heat contained in semi-coke, a variety of technical solutions have emerged and been applied over the years, such as the recovery of hot air using a fluidized bed, and the water cooling method using a vertical gravity bed structure. However, the above semi-coke cooling and waste heat recovery methods are all indirect conversion methods, and there is still the problem of reusing the recovered heat energy, and the efficiency is generally not high. Therefore, the most efficient and reasonable method for hot sem...
