Description
Technical field
The present invention relates to rotary reaction furnace field, especially a kind of double-layer furnace body rotary reaction furnace.
Background technique
Rotary reaction furnace, also known as rotary kiln are widely used in the industries such as chemical industry, cement, ceramics and lime, for calcine or
It is pyrolyzed the apparatus for rotating of corresponding goods and materials.Currently, such domestic rotary kiln or rotary reaction furnace are single layer cylinder revolving structure, but
In recent years as the development of shale oil Refining Technologies, China have introduced ATP furnace from Krupp, be a kind of pair of oil shale preheated,
Destructive distillation and the rotation container for therefrom separating hydrocarbon, are made of preheating section, retort section and burning zone.
ATP furnace structure and technique: oil shale enters ATP processor preheating section, which is located in external furnace body, by multiple pre-
Heat pipe composition, one end are connect with external furnace body end, and the other end is connect with retort section inner furnace body, and is rotated together with furnace body, to oil
Shale is preheated.Oil shale after the preheating of preheated section of economizer bank enters retort section and carries out destructive distillation, and directly with carry out spontaneous combustion
The thermal cycle solid mixing of section, provides and oil shale is further heated to pyrolysis temperature, and generate two kinds of products: (1) by the hydrocarbon gas
The steam stream that body and liquid distillate are constituted；(2) it is remaining to deposit to coke on shale particle, steam stream is from the retort section under flue
Oil recovery system is extracted and is delivered to, the solid of coking enters burning zone from retort section.Burning zone is located in external furnace body, into combustion
Source of the coke of the coking solid of section as process heat is burnt, is burnt in burning zone, the waste heat needed is by being deposited on combustion
The auxiliary fuel burnt in section end-rack is provided through auxiliary burner burning, will be sent into destructive distillation after the hot solids continuous heating in burning zone
Section provides the heat that destructive distillation needs.
From the foregoing, it will be observed that ATP furnace external furnace body overall length is whole furnace body, inside according to functional requirement be divided into three sections, preheating section
Positioned at external furnace body front end, You Duogen economizer bank composition is preceding to connect with external furnace body, connect afterwards with destructive distillation furnace body；Retort section is located at outer
Furnace body middle front part is made of the support connection device between inner furnace body and interior external furnace body, support connection device be located at inner furnace body into
Expect end, the entire inner furnace body of cantilever support and dry rectificating oil shale weight；Burning zone is located at external furnace body rear end, burning zone by combustion chamber,
The composition such as auxiliary burner, auxiliary fuel end-rack.It can be seen that it is inside and outside furnace structure that it is a bit of, which to only have middle front part, for ATP furnace, it is single
Section cantilever support, is only applicable to this typical process of oil shale retorting, and purposes is limited.
The patent application of Publication No. CN105419819A discloses a kind of simultaneous sealing of the integrated feedstock for rotary furnace
Device and its technique, disclosed in rotary furnace include revolution furnace body, flue gas chamber, exhanst gas outlet and smoke inlet, described time
Rotary furnace body is cylindrical shape, and the periphery for turning round the interlude of furnace body is equipped with flue gas chamber, and the flue gas chamber is equipped with exhanst gas outlet, should
One end of exhanst gas outlet is connected to flue gas chamber, and the other end is directly connected to the waste heat boiler of subsequent technique；The flue gas chamber
Body is additionally provided with smoke inlet, which is connected to flue gas chamber, and the high-temperature flue gas imported is equably to revolution furnace body
Interlude is heated, and realizes that heat absorption achievees the purpose that turn round furnace interior material.With such a configuration, it is normally transporting
Turn under state, utilizes heel row through waste heat boiler again after exchanging heat with revolution furnace body into the high-temperature flue gas inside flue gas chamber
Out, the generated heat in sludge handling process can be effectively utilized, the energy is saved greatly.High-temperature flue gas with wanted
The material of heating is isolated, and avoids the various harm that heat medium and material directly contact may cause, such as: heat medium
It is contaminated, cannot recycle, heat medium reacts with material and impacts to product quality, and heat medium and material are sent out
Raw reaction sets off an explosion.
The rotary furnace has revolution furnace body and flue gas chamber double-layer structure because should guarantee high-temperature flue gas smoothly connect into
Enter flue gas chamber, guarantees power and the support of revolution furnace body rotation again, maintain static dynamic flue gas chamber and only cover revolution
The middle section of furnace body can connect the pipeline of high-temperature flue gas, for being passed through the intracorporal material of high-temperature flue gas heating rotary furnace, return
The part that flue gas chamber is extended at the both ends of rotary furnace body can be used for connecting the support and power device of revolution.But the rotary furnace
There are still some problems:
First, flue gas chamber is only capable of the middle section of covering revolution furnace body, that is to say, that only turn round the middle section of furnace body
Good heating can be obtained, the middle section that only material reaches revolution furnace body could obtain enough heating temperatures；
Second, since bracket, the transmission device of revolution furnace body can only be arranged in the part that flue gas chamber is extended at its both ends,
Certain length must be limited by flue gas chamber, otherwise not can guarantee the stability of support and the revolution of revolution furnace body, thus is returned
The length limited of effective bringing-up section of converter is unable to satisfy the technique requirement of some productions and realization；
Third, revolution furnace body both ends have longer part to extend flue gas chamber, which is directly exposed to outside air
In, it will lead to heat and largely scatter and disappear.
