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
The invention belongs to the comprehensive utilization of coal material, energy-conserving and emission-cutting technology field, be specifically related to a kind of coal decomposition device.
Background technology
In known technology, have and utilize coal coal gas processed, have and utilize the coal preparing natural gas, utilize in addition coal to carry out high temperature, middle temperature, semi-coking, gas processed, but above-mentioned processing method is not rolled into a ball into piece by coal dust, will screen the piece material exactly, raw materials cost increases, or institute's aerogenesis calorific value is not high, and added value is little, and economic benefit and social benefit are not remarkable.It is hybrid that the type of heating of stove can be divided into the outer heat of external-heat, internal heat type and interior heat.The heating medium of external-heat stove does not directly contact with raw material, and heat is imported into by furnace wall; The heating medium of internal heat type stove directly contacts with raw material, because the difference of heating medium has two kinds of solid heat carrier method and air heat support methods.
Current, coal resolving device commonly used is mainly to have two kinds, and having a kind of is the shaft furnace structure, and the inflammable gas that this structure combustion product gases and coal produce, make the purity of combustible gas low, and added value is low, also has part to discharge, and causes a large amount of wastes of resource and the pollution of environment.Another kind of shaft kiln is that coal cinder is placed on dividing plate with holes, coal cinder top having heaters, because the coal cinder on dividing plate has certain ulking thickness, can not be by homogeneous heating, decomposition, need to heat with the gas circulation that is decomposed, decompose, what is more important, because a large amount of existence of coal dividing plate cocycle ventilating pit, coal dust can leak down from ventilating pit, so when coal dust need to enter shaft kiln, first need coal dust is processed to coal-forming group, so coal dust can not be directly used in the kiln body, separate, this has just correspondingly increased the cost that coal dust decomposes, and has reduced economic benefit.
A kind of coal decomposition device is arranged, comprise an airtight kiln body with opening for feed and discharge port, flame feed channel heating arrangements is set in described kiln body, the coal material that forms between described flame feed channel heating arrangements and kiln body inwall advances decomposition channels, and the coal decomposed gas collecting pipe that advances decomposition channels to be communicated with the coal material is set on described kiln body.Although also realized the purer decomposition and separation of coal material, its rotating kiln body has limited the quantum of output of product, and inner water back comes the effect of the outer coal dust of water back not ideal enough, can not meet the need of production that fast decoupled separates.
Summary of the invention
The present invention is for solving the problem that exists in above-mentioned technique and method, proposed a kind of more rapidly by coal dust separating substances, the coal decomposing equipment that safer, rate of heat exchange is higher.
A kind of coal decomposing equipment, comprise a sealing rotary kiln body, the coal material is set in described kiln body and advances the decomposition pipeline, described coal material advances and decomposes install pipeline coal inlet, coal outlet and decomposed gas collecting pipe, described coal material advances to decompose between pipeline and kiln body inwall and forms the heat exchange storehouse, it is helical pipe that described coal material advances the decomposition pipeline, described helical pipe one end arranges the charging cabinet, described charging cabinet is communicated with described coal inlet, the other end arranges the discharging cabinet, and described discharging cabinet is communicated with coal outlet.
Described heat exchange storehouse is connected with gas heating mechanism, and described heat exchange storehouse arranges the heat air export mouth.
Described gas heating mechanism comprises fuel supply pipe, air supply pipe and combustion chamber.
Described gas heating mechanism is electric heating mechanism.
The cross section of described helical pipe is circle, trilateral, tetragon or hexagon.
Described helical pipe is many densely arranged pipes.
Because arranging the coal material in high temperature kiln body, the present invention advances the decomposition pipeline, in high temperature kiln body, a large amount of warm airs surrounds coal material propelling decomposition pipeline and conducts, is radiated the coal material and advances on the coal dust that decomposes in pipeline, coal dust absorbs fully, coal dust heats up and decomposes, and resolves into the coal that combustion gas, tar gas and calorific value are higher in the coal material advances separating pipe.Kiln body of the present invention, by rotating, drives the coal material that is arranged in helical pipe and pushes ahead, and has improved charging capacity and discharging speed.By the mode of helical pipe, improved the active path of coal material in the heat atmosphere, improved the efficiency of thermal absorption, brought and decomposed more fully effect.Gas to the coal material heats, heat the coal in the kiln body with the form circulation of gas, and heat energy further takes full advantage of on the one hand, has improved the utilization ratio of heat, has reduced thermal losses, has also reduced in addition the quantity discharged of waste gas.The energy is fully saved and utilized to device disclosed by the invention, by fine coal decomposition and separation quickly and efficiently,, improved widely the utilization ratio of coal resource and utilized level, will bring a large amount of economic benefits and social benefit for entire society.
