Sealed rotating type low-moisture coke quenching and discharging device

Abstract

The invention provides a sealed rotating type low-moisture coke quenching and discharging device, which is assembled on a coke discharging bin in an internal combustion vertical carbonization furnace unit, and is provided with a spray head for spraying coke quenching water and a valve core with a rotating function, wherein when the valve core rotates, the coke quenching water can be effectively sprayed to semi-quenched and stirred semi-coke, so that the semi-coke can fully absorb moisture to reduce the temperature and can uniformly absorb moisture. According to the invention, the sealing performance of the system in the coke discharging process is ensured through sealed rotating coke discharging; and the coke quenching water can be uniformly sprayed on semi-coke through the rotating valve core, so that the problems of non-uniform coke quenching, false quenching due to heat clamping, non-uniform water content and the like in the prior art are effectively solved.

Description

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