Method for generating power and producing cement clinker from oil shale slag and combustible gas

Abstract

The invention discloses a method for power generation and for making cement clinker with oil shale residue and flue gas, wherein, oil shale is fed into the an oil shale separator for heating and dry distillation to produce shale oil-gas, then shale oil, flue gas and oil shale residue can be obtained through treatment in a shale oil condenser. The oil shale residue and cement addictive can be crushed and mixed with flue gas prior to injecting into the combustion chamber of furnace, and then thermal energy can be generated through combustion to drive the generating unit for generating purpose. The shale slag following the combustion can be used as cement clinker directly. The invention employs directly the flue gas and shale oil residue generated in the process of dry distillation as the solid and gas flue to achieve thermal generation and cement clinker, thereby allowing comprehensive utilization of oil shale, avoiding environmental pollution and land consumption, which is suitable for shale oil extracting, cement clinker making and power generating application.

Description

technical field [0001] The invention proposes a method for generating electricity and producing cement clinker by using oil shale slag and combustible gas in the field of energy and building materials. Background technique [0002] Before the patent of the present invention was proposed, the shale slag after extracting shale oil from oil shale was piled up in the open air, which not only occupied land but also affected the surrounding environment. Utilizing it to manufacture cement clinker still needs to carry out transportation, raw material batching and calcination, and economy is not good, causes high cost, affects its use. [0003] In the process of oil extraction, a large amount of combustible gas is produced, which cannot be directly used or discharged, resulting in waste of energy and pollution of the environment. Contents of the invention [0004] In order to use shale slag to generate electricity and calcinate cement clinker at the same time, the present inventio...
