Problems solved by technology

Although the relatively pure decomposition and separation of coal substances has been realized, the output of the product is limited by the rotating kiln body, and the effect of internal heating pipes to heat the pulverized coal outside the pipes is not ideal, which cannot meet the production needs of rapid decomposition and separation.
In addition, regardless of whether the heating system is at the periphery or the coal decomposition space is at the periphery, the rotary sealing problem will easily affect the isolation of the decomposition gas and the heating gas, thereby affecting the purity of the coal decomposition products

Abstract

The invention discloses a gravity-pushed coal-material decomposing device which comprises a sealing kiln body, wherein the kiln body is internally provided with a coal-material pushed decomposing pipeline which is provided with a coal inlet, a coal outlet and a decomposed gas collecting pipe; a material speed-controlling pusher is arranged in the coal-material pushed decomposing pipeline; a heat exchange bin is formed between the coal-material pushed decomposing pipeline and the inner wall of the kiln body; the heat exchange bin is connected with a high-temperature gas heating mechanism; and the heat exchange bin is provided with a heating air conduction outlet. In the invention, because the coal-material pushed decomposing pipeline is arranged in the high-temperature kiln body, a large amount of hot air in the high-temperature kiln body surrounds the coal-material pushed decomposing pipeline and is conducted and radiated on coal dusts in the coal-material pushed decomposing pipeline, thus completely absorbing the coal dusts and heating and decomposing the coal dust at the time of temperature rise.

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 gravity-propelled coal substance decomposition equipment. 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 in...
