Abstract
The utility model discloses composite spiral bin type coal material decomposing equipment, which comprises a sealed rotary kiln body where a coal inlet and a coal outlet are arranged, wherein a coal decomposition gas collecting pipe is arranged in the kiln body; two parallel spirals are arranged on the coal decomposition gas collecting pipe and divide the inner space of the kiln body into a gas heating bin and a coal material decomposing bin; and the coal decomposition gas collecting pipe is communicated with the coal material decomposing bin through a gas guiding hole arranged in the coal material decomposing bin. As the inner part of the kiln body is divided into the gas heating bin and the coal material decomposing bin which are separated from each other in the composite spiral bin type coal material decomposing equipment, a lot of high-heat gas in the heating gas guides and radiates heat energy onto coal powder in the coal material decomposing bin, so that the coal powder can sufficiently absorb the heat energy, and are decomposed as the temperature of the coal powder rises, and is decomposed into fuel gas, tar gas and coal with higher heat value in the coal material decomposing bin.
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 composite screw storehouse formula 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, 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, and in actual process, this solid matter pipeline is very complicated in technology, and because be that thermal radiation is main form, heat passage effect is not good enough.Another kind of situation is provided with solid matter coal material decomposition pipeline in kiln body inside, pipeline outer setting heat storehouse, and the pipeline technology of this mode propelling coal at first is also very complicated, and push structure is not easy to seal with pipeline and is connected in addition, and heat exchange also is difficult to fully.
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 coal dust separating substances, safer, technology is simpler, rate of heat exchange is higher composite screw storehouse formula coal material decomposition equipment.
A kind of composite screw storehouse formula coal material decomposition equipment, comprise that is provided with a coal inlet, the sealing rotary kiln body of coal outlet, the coal branch collection tube of venting one's spleen is set in the described kiln body, described coal branch is vented one's spleen the parallel spiral of twice is set on the collection tube, the interior edge of described spiral and the coal branch collection tube of venting one's spleen closely is connected, the outer closely is connected with kiln body inwall, the parallel spiral of described twice is divided into heat air storehouse and coal material decomposition storehouse with the kiln intracorporeal space, described heat air storehouse is connected with heating arrangements, and the heat air export mouth is set, described coal material decomposition storehouse is connected with coal inlet, the other end is provided with coal outlet, and the described coal branch collection tube of venting one's spleen is communicated with coal material decomposition storehouse by the gas port that is arranged in the coal material decomposition storehouse.
Described heating arrangements comprises fuel supply pipe, air supply pipe and combustion chamber.
Described gas heating mechanism is an electrically heated mechanism.
On the described spiral conducting strip is set.
Because the utility model is provided with the coal branch collection tube of venting one's spleen in the kiln body, described coal branch is vented one's spleen the parallel spiral of twice is set on the collection tube, heat air storehouse and the coal material decomposition storehouse that is isolated from each other will be divided in the kiln body, the interior a large amount of hot gas of heat air interlocks compound with coal material decomposition storehouse and contacts by helicoidal surface, heat is conducted, be radiated on the coal dust in the coal material decomposition storehouse, coal dust absorbs fully, coal dust heats up and decomposes, and in coal material decomposition storehouse, resolve into combustion gas, the coal that tar gas and calorific value are higher, the coal branch is vented one's spleen and is effectively fast collected by the coal branch with holes collection tube of venting one's spleen, and after deriving the kiln body, enter finishing sequence.The utility model kiln body drives the twice spiral, and the coal material in the coal material decomposition storehouse is pushed ahead by rotating, and the kiln internal screw distribution mode of high utilization rate has improved charging capacity and discharging speed.By the compound mode of cutting apart kiln space of duplex, improved the active path of coal material in the heat atmosphere, improved heat air storehouse and the contact area in coal material decomposition storehouse and 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 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.
