Abstract

The invention provides a sealed rotary low-moisture coke quenching and coke discharge device. The coke discharge chamber in the internal combustion vertical carbonization furnace unit is equipped with a sealed rotary low-moisture coke quenching and coke discharge device, and the sealed rotary low-moisture coke quenching and coke discharge device The device is equipped with a spray head for spraying coke quenching water and a valve core with a rotating function. When the valve core is rotating, it can effectively spray the quenching water onto the half-extinguished and stirred semi-coke, which is beneficial to fully extinguishing the semi-coke. Absorb moisture to lower the temperature, and help the semi-coke to absorb moisture evenly. The invention guarantees the sealing performance of the system during the coke discharge process by sealing and rotating the coke; through the rotating valve core, the coke quenching water can be evenly sprayed on the semi-coke On the one hand, it effectively solves the problems of uneven coke quenching, false extinguishing caused by heat, and uneven water content in the prior art.

Description

technical field [0001] The invention relates to the technical field of medium and low temperature pyrolysis in coal chemical industry, in particular to a sealed rotary low-moisture coke quenching and discharging device. Background technique [0002] Using Jurassic non-caking coal and weakly caking coal as raw materials to produce high-quality blue carbon, and at the same time obtaining more coal tar as the target product, the basic process is: medium and low temperature - internal heat type - gas heat carrier - air isolation pyrolysis process. The pyrolysis temperature is controlled at 650-750°C, and the hot blue carbon is cooled to below 260°C through a water jacket. At present, the subsequent sealing cooling and coke removal basically adopts water sealing for cooling, that is, water for coke removal, and the moisture content is generally 18-20%. If the water content of blue charcoal is too large, it needs to be dried by direct combustion of gas, which consumes energy and...
