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 an external heating coal decomposing equipment with fold pipes, comprising a sealed kiln body, wherein the kiln body is 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 and are arranged in the form of multi-layer fold line pipes; each layer of pipe is provided with a screw propeller; the screw propellers are connected with rotary power linkage mechanism by gears extending out of the kiln body; heat exchange bins are formed between the coal propelling and decomposing pipes and the inner wall of the kiln body; and the heat exchange bins are provided with a heated gas outlet. As the high temperature kiln body is 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 the coal dust in the coal propelling and decomposing pipes, and the coal dust fully absorbs the hot air and is heated and decomposed and is 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 specifically relates to a folded tube external heating type coal material decomposition equipment. Background technique [0002] Among the known technologies, some use coal to make gas, some use coal to make natural gas, and some use coal for high-temperature, medium-temperature, and low-temperature coking and gas production. However, the above-mentioned process methods are not enough to form coal powder into agglomerates. When selecting blocks, the cost of raw materials increases, 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 mixed internal heating and external heating. The heating medium of the external heating furnace is no...
