ActiveCN101942313AGuaranteed to be heatedGuaranteed temperature requirementsDirect heating destructive distillationCombustible gas purificationHeat carrierCooling tower
The invention provides a process and device for carrying out stage dry distillation on oil shale under the state of full recycle, with the gas as the heat carrier. The oil shale is divided into three different sizes (such as 0-6mm, 6-20mm and 20-50mm) through crushing and screening, and the oil shale is firstly dried and heated to the temperature between 50 DEG C and 150 DEG C by the waste smoke exhausted from gas heating furnaces and then enters into the different sizes of furnaces for dry distillation to undergo dry distillation. After being treated by water spraying and an indirect cooling tower, a rotary trapper and an electric trapper for oil collection, the dry distillation oil and gas undergo oil-gas-water separation, and after separation, the oil enters into a storage tank, the water enters into a circulating water tank and the first part of gases serves as the heat carrier and is recycled, the second part of gases is used as the fuels for the heating furnaces and the third part of gases is used as the fuel gases for power generation.
