Embodiment 1

[0052] The oil shale dry distillation system includes a dry distillation reaction unit 1 and a condensation recovery system 3. The condensation recovery system 3 mainly includes a three-stage condensation system composed of an air cooler 310, a water cooler 320, and a deep cooler 330 arranged in sequence according to the condensation recovery route. In the recovery system, the bottom of each cooler is equipped with a shale oil discharge pipeline; the dry distillation product release end A of the dry distillation reaction device 1 and the dry distillation product receiving end B of the condensation recovery system 3 pass through the gas dust removal system 2 Connected, the gas dedusting system 2 includes a first gas purification unit 210 and a second gas purification unit 220 arranged at the front end of the first gas purification unit 210 according to the dust removal and purification direction. The second gas purification unit 220 adopts a gravity dust collector, and the first ...

Abstract

The invention discloses a system for making oil by retorting oil shale. By the system, the yield of oil sludge can be reduced. The system comprises a retorting reaction device, a condensation recovery system, wherein the retorting product releasing end of the retorting reaction device is connected with the retorting product receiving end of the condensation recovery system through a gas dedusting system; the gas dedusting system at least comprises a first gas purification unit; and the first gas purification unit takes a porous filtering material of which the filtering precision is 0.01 to 80 micrometers as a filtering element. The retorting product is purified by the porous filtering material of which the filtering precision is 0.01 to 80 micrometers before condensation, so that the dust content of the retorting product can be greatly reduced, and the yield of the subsequent oil sludge is reduced. The system is particularly suitable to serve as a system for making the oil by using a retorting gas heat carrier in an internal heating mode.

Description

technical field [0001] The invention relates to an oil shale upground retorting technology, in particular to an oil shale retorting oil production system. Background technique [0002] There are two types of oil shale retorting: underground retorting and upground retorting. Among them, although the underground dry distillation technology has been patented by Shell, it is still in the research and development stage and has no industrial application. Aboveground dry distillation is still the main way to develop and utilize oil shale. Oil shale aboveground dry distillation is divided into two types: external heat dry distillation and internal heat dry distillation. External heat dry distillation means that the heat carrier heats the oil shale in the furnace for dry distillation through the furnace wall. This technology has been eliminated; internal heat dry distillation means that the heat carrier directly contacts with oil shale in the furnace for dry distillation. Mainstre...
