Grinding-disc pyrolysis reactor

Abstract

The invention provides a grinding-disc pyrolysis reactor. A main body of the grinding-disc pyrolysis reactor consists of an upper furnace plate, a distributing plate, dust boards and scraping plates which are rotatable around a feeding pipe, and a lower furnace plate and a furnace wall which are fixed, wherein a the feeding pipe is arranged in the center of the furnace plate, and the distributing plate is arranged at the bottom of the furnace plate; a circle of dust boards and a pair or a plurality of pairs of scraping plates are arranged at the periphery of the distributing plate; a water seal or a sand seal is arranged between the upper furnace plate and the feeding pipe as well as the upper furnace plate and the furnace wall; the distributing plate is a mosaic grinded surface with a plurality of radial tooth grooves formed in the mosaic grinded surface, and through the rotation of the distributing plate, material distributing, turning and discharging functions can be achieved simultaneously; and the lower furnace plate is a flat thermal storage heating stove. The reactor is simple in structure, reliable in operation, convenient to maintain, large in productive capacity, wide in raw material adaptability, and especially suitable for pyrolysis of low metamorphic coal, oil shales, oil sand, biomasses, junked tires, plastic, garbage and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a disc-type pyrolysis reactor for polymeric organic matter. Background technique [0002] Low-metamorphic coal (lignite, long-flame coal), oil shale, oil sand, biomass, waste tires, garbage and other materials are characterized by high volatile content and high oil content. Such resources are very abundant in China. In today's situation where the supply of oil and natural gas is becoming increasingly tense and the oil shortage is reappearing, how to extract and utilize the precious oil and gas components in such resources will alleviate the situation that my country's oil and natural gas resources are overly dependent on imports and seriously threaten my country's energy security. Significant. [0003] Pyrolysis is a technology that causes the material to undergo a cracking reaction under high temperature conditions by heating, and then generates tar and gas. It has t...

AI Technical Summary

Problems solved by technology

The system has a simple structure and a large amount of raw coal to be processed. However, due to the internal heating of the gas carrier, the pyrolysis gas is mixed with the flue gas, so the obtained coal gas contains more useless components and has a lower calorific value.

Moreover, the grate holes will gradually be blocked due to tar coking, resulting in poor flue gas circulation.
