Description
Technical field
The invention belongs to the comprehensive utilization of coal material, energy-conserving and emission-cutting technology field, be specifically related to pusher coal material decomposition equipment in a kind of pipe.
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 equipment 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.In addition, heating arrangements is arranged on the inside of kiln body, increases the difficulty that it installs maintenance, also is unfavorable for safety in production simultaneously.
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, energy-saving and emission-reduction, thereby pusher coal material decomposition equipment in the pipe that improves the economic and social benefits.
Pusher coal material decomposition equipment in a kind of pipe, comprise a sealing 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, the revolving power mechanism external with being arranged on kiln is connected, described coal material advances to decompose and forms the heat exchange storehouse between pipeline and the kiln body inwall, described heat exchange storehouse is connected with the high-temperature gas heating arrangements by inlet pipe, and described heat exchange storehouse is provided with the heat air export mouth away from high-temperature gas heating arrangements one side.
Described high-temperature gas heating arrangements comprises fuel supply pipe, air supply pipe and combustion chamber.
Described coal material advances the decomposition pipeline to be made up of many parallel solid matter pipelines, and described many parallel solid matter pipeline one ends are provided with the charging cabinet, and described charging cabinet is communicated with described coal inlet, and the other end is provided with the discharging cabinet, and described discharging cabinet is communicated with coal outlet.
Described coal material advances and decomposes the spiral propeller that pipeline comprises that pipeline is interior with being arranged on pipeline, and spiral propeller is connected with revolving power mechanism by stretching out the external gear of kiln.
Described heat air export mouth is communicated with by return line with inlet pipe, and described return line is arranged in the described combustion chamber.
The gas circulation blower fan is set in the described return line.
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 no longer rotates, the restriction that no longer is subjected to kiln body diameter and is difficult to rotate, advance the propelling of realization coal material in pipeline that slowly run of decomposing pipeline with the coal material, charging capacity and discharging speed have been improved, bottom heating and top go out heat structure and make the generation of heat conduct more to meet the fuel combustion rule that heats is better in addition.Warm air beating mechanism is arranged on the outside of kiln body, reach the operation of controlledization of dangerous position, improved device ', easy access and maintenance, it is produced in addition and packaging technology is the simplification state than prior art, and reliability and stability further strengthens.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.
