Dry distillation device for oil shale processing

Abstract

The invention belongs to the technical field of oil shale processing. The invention particularly relates to a dry distillation device for oil shale processing. The problem that in the prior art, the dry distillation effect on oil shale is poor is solved. The following scheme is proposed: the device comprises a dry distillation kettle, wherein a feeding pipe is arranged at the top of the dry distillation kettle; filter screen plates are arranged at the bottom in the dry distillation kettle; air inlet pipes and an air outlet pipe are respectively arranged at parts, below and above the filter screen plate, of the dry distillation kettle; a water bath shell wraps a part, located at the tops of the filter screen plates, of the outer wall of the dry distillation kettle, the inner wall of the drydistillation kettle is of a square structure, the inclined filter screen plates are fixed to the bottoms of the inner walls of the two sides of the dry distillation kettle, the filter screen plates incline downwards towards the side away from the inner wall of the dry distillation kettle, and a vibrating screen is connected to the bottom end between the two filter screen plates through torsionalsprings. The air inlet pipes are arranged on the two sides of a bearing surface, crushed solid components on the bearing surface are screened out from the middle position through a vibrating screen, and the situation that air circulation is affected due to the fact that meshes of the whole bearing surface are blocked is avoided.

Description

technical field [0001] The invention relates to the technical field of oil shale processing, in particular to a dry distillation device for oil shale processing. Background technique [0002] Oil shale belongs to unconventional oil and gas resources. It is listed as a very important alternative energy source in the 21st century due to its rich resources and feasibility of development and utilization. It is a non-renewable fossil energy like oil, natural gas and coal. Oil shale is subjected to carbonization processing to obtain oil. The technology used in the prior art for oil shale carbonization is mainly a gas heat carrier carbonization method. [0003] For the dry distillation of oil shale gas heat carrier, the oil shale fragments are generally put into the dry distillation kettle and carried by the mesh plate, and the hot air flow is passed upward from the bottom of the mesh plate for dry distillation, and the oil is discharged from the top with the air flow Sieve out th...
