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 gas purification system capable of utilizing slag heat. The gas purification system comprises a reactor used for producing dust-containing gas and a gas dust collector connected with a dust-containing gas release end of the reactor. The gas dust collector is provided with a slag removal unit; a heat exchange system is arranged between the reactor and the gas dust collector and comprises a first flow path and a second flow path in heat exchange connection through a heat exchanger, the first flow path is a raw material feeding channel of the reactor, the second flow path is a slag removal channel of the gas dust collector, and the slag removal channel is connected with the slag removal unit. The gas purification system provided by the invention can preheat a raw material entering into the reactor by using slag in the gas dust collector, which enables energy to be saved.

Description

technical field [0001] The invention relates to a gas purification system capable of realizing slag heat utilization. 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. Mainstream technologies for shale development...
