Problems solved by technology

[0003] At present, there are mainly two types of commonly used coal decomposition equipment. One is a vertical kiln structure, which burns flue gas and combustible gas produced by coal, making the combustible gas low in purity and low in added value, and some of it is discharged, causing 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 there is a heater above the coal block. Because the coal blocks on the partition have a certain accumulation thickness, they cannot be heated and decomposed evenly, and the decomposed gas needs to be used to Circular heating, decomposition, and more importantly, because of the existence of a large number of circulation vent holes on the coal separator, coal powder will leak from the vent holes, so when coal powder needs to enter the shaft kiln, it needs to be processed into coal lumps first, Therefore, pulverized coal cannot be directly used for kiln body separation, which correspondingly increases the cost of pulverized coal decomposition and reduces economic benefits

Abstract

The invention discloses a bent pipe heating type coal substance decomposer comprising a sealed rotary kiln body with a feed hole and a discharge hole, wherein a flame pipeline heating mechanism is arranged in the kiln body; a coal substance propelling and decomposing channel is formed between the flame pipeline heating mechanism and the inner wall of the kiln body; the kiln body is provided with a coal decomposed gas collection tube communicated with the coal substance propelling and decomposing channel; and a flame radiating pipe is a helical pipeline the external circumstance of which is arranged on the inner wall of the kiln body. Because the coal substance propelling and decomposing channel is arranged in the high-temperature kiln body, a great quantity of hot air in the high-temperature kiln body surrounds the coal substance propelling and decomposing channel and are conducted and radiated to coal dust in the coal substance propelling and decomposing channel; and the coal dust fully adsorbs the hot air, so the coal dust is heated and decomposed, and the coal substance is decomposed into gas, tar gas and coal with high calorific value in the coal substance propelling and decomposing channel.

Description

Technical field [0001] The present invention is a comprehensive utilization of coal material and energy conservation and emission reduction technology, which involves a variety of heating coal decomposition devices. Background technique [0002] In public technology, there are those who use coal to make gas, some use coal to make natural gas, as well as the use of coal for high temperature, medium temperature, low temperature refining, and gas making, but the above process methods are either made of coal pourgea, or they must be or need to be made of pieces, or they must be or need to be made of pieces.Screening block, increased raw material costs, or the heat value for gas, the added value is not large, and the economic benefits and social benefits are not significant.The heating method of the furnace can be divided into external thermal, internal heat, and internal heat hybrid hybrid.The heating medium of the outer heating furnace does not contact the raw material directly, and...
