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 the circulating coal material of a kind of heat air specific 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.In order to obtain more purified coal material decomposition gas, we will heat the thermal source part and stretch out the coal material decomposition with the form of flame feed channel and advance passage, reach the coal branch comparatively purified purpose of venting one's spleen.But in the process of actual production, the water back manufacture craft of each solid matter is very complicated on the one hand, may there be gas leakage in seal form, scurries phenomenon mutually, and then there is certain potential safety hazard, particularly the flame gas of flame gas water back converges vent one's spleen dual rotation elevated-temperature seal problem between the collection tube of pipe and coal branch, also perplexs the fast development of resolving device always.The burner that problem takes place in addition easily partly is arranged on kiln body inside, is unfavorable for detecting, overhauls and in time grasp burning dynamically, has improved safe blind spot quantity.
The utility model content
The utility model is for solving the problem that exists in above-mentioned technology and the method, proposed a kind ofly not introduce impurity, guarantee to divide vent one's spleen pure, substantially must external heat source, the circulating coal material decomposition of self-centered heat air equipment.
The circulating coal material of a kind of heat air specific equipment, the sealing kiln body that comprises a band opening for feed, discharge port, the coal material is set in the described kiln body advances decomposition mechanism, one end of described sealing kiln body is provided with the coal branch collection tube of venting one's spleen, the other end is provided with the high-temperature gas input tube, the described coal branch collection tube of venting one's spleen is connected with gas aftertreatment mechanism, and is communicated with the high-temperature gas input tube by the winding pipe, and described winding pipe is or/and be provided with heating arrangements on the high-temperature gas input tube.
Described heating arrangements comprises fuel supply pipe, air supply pipe and combustion heating chamber.
Described fuel supply pipe is communicated with by gas aftertreatment mechanism and the coal branch collection tube of venting one's spleen.
Described heating arrangements is an electrically heated mechanism.
Because the utility model branch is vented one's spleen as the medium of heat transmission, the coal branch that will produce in high temperature kiln body is vented one's spleen or inertia enters the kiln body after by water back once more, high-temperature gas directly fully contacts with the coal dust that stirs, coal dust can absorb heat fully, and the decomposition that is rapidly heated, and resolve into more coal branch at the kiln body and vent one's spleen and the higher coal of calorific value, during the coal branch is vented one's spleen most collected by gas aftertreatment mechanism, dedusting, separate, pressurized liquefied, the higher coal of calorific value flows out from coal outlet, sub-fraction coal branch is vented one's spleen or is passed through isolating rare gas element by after heating, enter the kiln body once more, carry out new reaction with undecomposed or initiate coal material, finish the vent one's spleen circulation of heating coal material of branch.Of paramount importance is that utilization divides vent one's spleen this kind gaseous media and coal contact reacts, does not introduce new any gas, has fundamentally guaranteed the pure of the finished product.And use rare gas element as heat-conduction medium, although many one rare gas element separable programmings, security improves greatly.The fuel that branch is vented one's spleen in the fuel supply pipe that heats also can use the coal branch after sub-fraction is handled to vent one's spleen, and this just no longer for the new thermal source of this system's interpolation, guarantees that it is self-sufficient.The energy is fully saved and utilized to 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.
