Abstract

The invention discloses a coal substance decomposing device, which comprises a sealed rotary kiln, wherein a coal substance propelling decomposition pipeline is arranged in the kiln, and is provided with a coal inlet, a coal outlet and a decomposition gas collecting pipe; and a heat exchange bin is formed between the coal substance propelling decomposition pipeline and the inner wall of the kiln, is connected with a gas heating mechanism and is provided with a heated gas outlet. The coal substance propelling decomposition pipeline is arranged in the high temperature kiln, a large amount of hot air in the high temperature kiln surrounds the coal substance propelling decomposition pipeline, heat transfers to and radiates coal dust in the coal substance propelling decomposition pipeline, and the coal dust fully absorbs the heat and is heated and decomposed into fuel gas, tar gas and coal with a higher heat value in the coal substance propelling decomposition pipeline.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of coal substances, energy saving and emission reduction, and in particular relates to a coal substance decomposition device. Background technique [0002] Among the known technologies, there are those that use coal to produce gas, some that use coal to produce natural gas, and those that use coal for high-temperature, medium-temperature, and low-temperature coking and gas production. Screening block materials will increase the cost of raw materials, or the calorific value of the produced gas is not high, the added value is not large, and the economic and social benefits are not significant. The heating method of the furnace can be divided into external heating type, internal heating type and internal heating and external heating mixed type. The heating medium of the external heating furnace is not in direct contact with the raw materials, and the heat is introduced from the fur...
