Problems solved by technology

[0002] The current dry distillation method uses a regenerative heating furnace device. When the gas is passed into the dry distillation furnace, the temperature generated goes from high to low, and then from low to high, forming an uneven temperature field, which causes the instability of the system pressure. And the instability of the carbonization temperature makes the carbonization efficiency very low and safety accidents occur frequently

Abstract

The invention provides a novel dry distillation method of an oil shale. The existing dry distillation method is of heat accumulation type heating, the temperature and the pressure in a furnace are not stable, resulting in safety accidents easily and low oil yield. In the method, cold gas is introduced into a combustion fire layer in a dry distillation furnace in a circulating way to exchange heat, thereby enabling the temperature in the furnace to be stable, lowering the incidence of the safety accidents and enhancing the oil yield.

Description

technical field [0001] The invention relates to a new oil shale dry distillation method. Background technique [0002] The current dry distillation method uses a regenerative heating furnace device. When the gas is passed into the dry distillation furnace, the temperature generated goes from high to low, and then from low to high, forming an uneven temperature field, which causes the instability of the system pressure. And the instability of the carbonization temperature makes the carbonization efficiency very low, and safety accidents occur frequently. Contents of the invention [0003] Book The purpose of the invention is to provide a new oil shale dry distillation method with stable cold gas temperature. [0004] Realize the technical scheme of the present invention as: [0005] The new oil shale carbonization method is characterized in that the cold gas is circulated and passed into the carbonization furnace for combustion and heat exchange. [0006] The beneficial...
