Technological complex for drying coal with a high yield of volatile substances, mainly brown coal

摘要

The utility model is aimed at the possibility of thermal drying of coal with a high yield of volatile substances, mainly brown, with minimal cost and energy costs. The technological complex for drying coal with a high yield of volatile substances, mainly brown, includes a drying unit with supply paths of raw coal and unloading the finished product, systems for supplying an inert drying agent and venting the exhaust gas stream with smoke exhausters, a heater for producing a hot inert gas agent. A heat generator with a source fuel bin, a blower fan and a mixer of hot inert and spent gas flows is used as a heater for producing an inert drying agent, and the complex is additionally equipped with a facility for classifying the initial coal, the unloading line of the top product of which is technologically connected to the coal supply system to the drying unit, and the unloading line of the bottom product to the source fuel bunker of the heat generator, besides the drying unit is equipped with an aspiration system, the exhaust pipe of which is hydraulically connected to the intake of the blower fan, and the exhaust gas exhaust system The flow is equipped with an additional gas duct with a flow regulator installed on it and a chimney. The utility model should provide explosion and fire safety during the drying process. preservation of volatile substances in the dried coal, economical operation. 1 il. In addition, the drying unit is equipped with an aspiration system, the exhaust pipe of which is hydraulically connected to the suction of the blower fan, and the exhaust gas exhaust system is equipped with an additional gas duct with a flow regulator and a chimney installed on it. The utility model should provide explosion and fire safety during the drying process. preservation of volatile substances in the dried coal, economical operation. 1 il.
