Problems solved by technology

[0003] In the traditional coal pyrolysis system, by putting coal into the retort furnace, the traditional retort furnace usually heats the coal through flame external heating and hot air, so that the coal is pyrolyzed in the retort furnace, and the gas generated after pyrolysis fills the whole In the carbonization furnace, and the traditional carbonization furnace is difficult to quickly dry the coal properly and fully pyrolyze, and the pyrolysis time of the traditional carbonization furnace is relatively long

Abstract

The invention discloses a coal pyrolysis system. The coal pyrolysis system comprises a bin (1), a moving bed and a microwave device (4), wherein the moving bed comprises a microwave dry distillation furnace section (3), the microwave device (4) feeds microwaves into the microwave dry distillation furnace section (3), and coal materials fed from the bin (1) can be pyrolyzed in the microwave dry distillation furnace section (3). Coal is taken as a pyrolysis raw material and subjected to dry distillation with a microwave radiation heating means, so that the coal pyrolysis system can speed up coal pyrolysis, the coal is pyrolyzed sufficiently, and the yield of a coal pyrolysis product is increased.

Description

technical field [0001] The invention relates to coal pyrolysis, in particular to a coal pyrolysis system. Background technique [0002] Because coal can produce combustible gas (coal gas), tar and semi-coke through pyrolysis, three types of chemical products and fuels with high utilization value. Therefore, the purpose of coal dry distillation is to make full use of the organic matter contained in coal to obtain coke and various valuable chemical products in addition to gas. Dry distillation gas is the earliest traditional gas source used as city gas. It is still the main source of city gas in areas where natural gas and oil-based gas are not widely developed. [0003] In the traditional coal pyrolysis system, by putting coal into the retort furnace, the traditional retort furnace usually heats the coal through flame external heating and hot air, so that the coal is pyrolyzed in the retort furnace, and the gas generated after pyrolysis fills the whole In the carbonization...
