Abstract
The utility model discloses a multiple-pipe external-heating type decomposing device for coal material, comprising a sealed kiln body, wherein the kiln body is internally provided with a coal material propelling-decomposing pipeline; the coal material propelling-decomposing pipeline is provided with a coal inlet, a coal outlet and a decomposed gas collecting pipe; a heat exchange bin is arranged between the coal material propelling-decomposing pipeline and the inner wall of the kiln body; the heat exchange bin is connected with a high temperature gas heating mechanism by an air inlet pipe; and the heat exchange bin is provided with a heated gas out-guide pipe. As the coal material propelling-decomposing pipeline is arranged in the high temperature kiln body, a large quantity of hot air in the high temperature kiln body encircles the coal material propelling-decomposing pipeline and is conducted and radiated to coal powder inside the coal material propelling-decomposing pipeline, and the coal powder sufficiently absorbs the hot air, so that the coal powder is heated and decomposed to form fuel gas, tar gas and coal with high heat value.
Description
Technical field
The utility model belongs to the comprehensive utilization of coal material, energy-conserving and emission-cutting technology field, is specifically related to a kind of multi-pipe external-heating coal material decomposition equipment.
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.
The utility model content
The utility model is for solving the problem that exists in above-mentioned technology and the method, proposed a kind of more apace with the coal dust separating substances, improve its comprehensive utilization value, energy-saving and emission-reduction, thereby the multi-pipe external-heating coal material decomposition equipment that improves the economic and social benefits.
A kind of multi-pipe external-heating coal material decomposition equipment, 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, and the support rotating 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, and described heat exchange storehouse is connected with the high-temperature gas heating arrangements, and described heat exchange is provided with the heat air export mouth on the storehouse.
Described high-temperature gas heating arrangements comprises fuel supply pipe, air supply pipe and combustion chamber.
Described high-temperature gas heating arrangements is an electrically heated mechanism.
Described high-temperature gas heating arrangements is arranged on the kiln external body.
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 heat air export mouth carries out preheating by pipeline to material.
Because the utility model 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.The utility model kiln body 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.The flame gas that produces carries out preheating by heat air outlet and pipeline to material, has improved the utilization ratio of heat, has reduced thermal losses.The energy is fully saved and utilized to the disclosed device of the utility model 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.
