Problems solved by technology

[0005] At present, there are mainly two types of commonly used coal decomposition equipment. One is the vertical kiln structure, which burns flue gas and combustible gas produced by coal, which makes the combustible gas have low purity and low added value, and some of it is discharged. Cause a lot of waste of resources and pollution of the environment
Another type of vertical kiln is that the coal blocks are placed on a partition with holes, and the heater is run above the coal block. Because the coal blocks on the partition have a certain thickness,

Abstract

The invention discloses external heating internal coal decomposing equipment, comprising a sealed kiln body, wherein the kiln body is internally provided with coal propelling and decomposing pipes; the coal propelling and decomposing pipes are provided with a coal inlet, a coal outlet and a decomposed gas collecting pipe; heat exchange bins are arranged between the coal propelling and decomposing pipes and the inner wall of the kiln body; the heat exchange bins are connected with a high temperature gas heating mechanism by a gas inlet pipe; and the heat exchange bins are provided with a heated gas delivery pipe at the side far away from the high temperature gas heating mechanism. As the high temperature kiln body is internally provided with the coal propelling and decomposing pipes, plenty of hot air in the high temperature kiln body surrounds the coal propelling and decomposing pipes and conducts and radiates heat to the coal dust in the coal propelling and decomposing pipes, and the coal dust fully absorbs the heat and is heated and decomposed into gases, tar gases and coal with higher heat value in the coal propelling and decomposing pipes.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of coal materials, energy saving and emission reduction, and in particular relates to an internal coal external heating type coal material decomposition equipment. Background technique [0002] Among the known technologies, there are those that utilize coal to produce gas, those that utilize coal to produce natural gas, and those that utilize 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 high, 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 ...
