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 material decomposition device.
Background technology
In known technology, the coal system of utilization coal gas is arranged, have and utilize the coal preparing natural gas, utilize coal to carry out high temperature, middle temperature, semi-coking, system gas in addition, but above-mentioned processing method is not coal dust to be rolled into a ball caked, 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 external-heat, internal heat type and the outer heat of interior heat.The heating medium of external-heat stove does not directly contact with raw material, and heat is imported into by the furnace wall; The heating medium of internal heat type stove directly contacts with raw material, because of the difference of heating medium has two kinds of the gentle body heat support methods of solid heat carrier method.
Current, coal resolving device commonly used mainly is 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 makes that the purity of combustible gas is 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 the dividing plate with holes, coal cinder top having heaters, because of the coal cinder on the dividing plate has certain ulking thickness, can not be by even heating, decomposition, need heat, decompose with the gas circulation that is decomposed, 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 coal dust need be processed coal-forming group earlier when coal dust need enter shaft kiln, separate so coal dust can not be directly used in the kiln body, this has just correspondingly increased the cost that coal dust decomposes, and has reduced economic benefit.
A kind of coal material decomposition device is arranged, comprise an airtight kiln body that has opening for feed and discharge port, flame feed channel heating arrangements is set in the described kiln body, the coal material that forms between described flame feed channel heating arrangements and the kiln body inwall advances decomposition channels, and the coal branch that is communicated with the coal material propelling decomposition channels collection tube of venting one's spleen is set on the 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 satisfy the production needs of quick decomposition and separation.
Summary of the invention
The present invention is for solving the problem that exists in above-mentioned technology and the method, proposed a kind of more apace with coal dust separating substances, safer, coal material decomposition equipment that rate of heat exchange is higher.
A kind of coal material decomposition equipment, comprise a sealing rotary kiln body, the coal material is set in the described kiln body advances the decomposition pipeline, described coal material advances and decomposes pipeline coal inlet, coal outlet and the branch collection tube of venting one's spleen is set, described coal material advances to decompose and forms the heat exchange storehouse between pipeline and the kiln body inwall, it is helical pipe that described coal material advances the decomposition pipeline, described helical pipe one end is provided with the charging cabinet, described charging cabinet is communicated with described coal inlet, the other end is provided with 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 is provided with the heat air export mouth.
Described gas heating mechanism comprises fuel supply pipe, air supply pipe and combustion chamber.
Described gas heating mechanism is an electrically heated mechanism.
The cross section of described helical pipe is circle, trilateral, tetragon or hexagon.
Described helical pipe is many solid matter pipelines.
Because the present invention will be provided with the coal material and advance 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 the pipeline in the high temperature kiln body, coal dust absorbs fully, coal dust heats up and decomposes, and resolves into the higher coal of combustion gas, tar gas and calorific value in the coal material advances separating pipe.Kiln body of the present invention drives the coal material that is arranged in the helical pipe and pushes ahead by rotating, 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 efficient of thermal absorption, brought and decomposed effect more fully.Gas to the coal material heats heats the intravital coal of kiln with the form circulation of gas, and heat energy further makes full use of on the one hand, has improved the utilization ratio of heat, has reduced thermal losses, has also reduced the exhaust gas discharging amount in addition.The energy is fully saved and utilized to device disclosed by the invention with fine coal decomposition and separation quickly and efficiently, improved the utilization ratio of coal resource widely and utilized level, will bring a large amount of economic benefits and social benefit for entire society.
