A kind of catalytic dry distillation equipment and dry distillation process of oil shale organic waste

Abstract

The invention relates to the field of dry distillation of oil shale, in particular to a catalytic dry distillation equipment for oil shale organic waste and a dry distillation process, including a dry distillation furnace body, a feeding component, a filtering component, a recovery component and a rock ash collection component. The cooperation of the feeding component and the supporting component is convenient to install the feeding component on the upper end of the retort furnace body, and the feeding component has a grinding function, which can regrind the oil shale entering the feeding component, which is convenient for oil shale The large particles in the raw material are pulverized; through the cooperation of the filter assembly and the feed assembly, it is convenient to filter the oil shale after the grinding of the feed assembly, so that the smaller particles of oil shale enter the interior of the retort furnace body, shorten the oil shale Combustion time to ensure complete combustion of oil shale, and the filter assembly is detachable, which is convenient to replace filters with different mesh sizes according to actual use requirements.

Description

technical field [0001] The invention belongs to the technical field of dry distillation of oil shale, and particularly relates to a catalytic dry distillation equipment and a dry distillation process of oil shale organic waste. Background technique [0002] Oil shale can be retorted at low temperature to obtain shale oil similar to crude oil, which can be made into gasoline, diesel oil or used as fuel oil. There are many types of shale retorting furnaces. According to the phase state of the heating carrier used, they can be divided into two categories: gas heat carrier retorting furnaces and solid heat carrier retorting furnaces. In the catalytic retorting of oil shale organic wastes, the oil shale powder needs to be retorted. Full combustion is carried out through dry distillation equipment, and the oil and gas produced by the combustion are collected and then processed. However, the existing dry distillation equipment suitable for catalysis of oil shale organic waste usual...

Problems solved by technology

[0002] After low temperature dry distillation of oil shale, shale oil similar to crude oil can be obtained, which can be made into gasoline, diesel oil or used as fuel oil. It is used for low temperature (about 500°C) dry distillation of oil shale to produce shale oil. The main equipment, oil There are many types of shale retort furnaces, which can be divided into gas heat carrier retort furnaces and solid heat retort retort furnaces according to the phase state of the heating carrier used. Oil shale powder is required for catalytic carbonization of oil shale organic waste Complete combustion is carried out through the retort equipment, and the oil and gas produced by the combustion are collected to process the oil and gas. However, the existing retort equipment suitable for the catalysis of oil shale organic waste usually does not have the function of crushing and screening oil shale rocks, so that the The size of the oil shale particles in the retort equipment is uneven, the burning time of the large particles of oil shale is long, while the burning time of small particles of oil shale is short, so that the oil shale is incompletely burned, so we need to propose a Catalytic carbonization equipment and carbonization process of oil shale organic waste
