Description
Technical field
The present invention relates to preheaters, and in particular to a kind of revolution kiln tail vertical preheater.
Background technique
Rotary kiln refers to rotary calcining kiln, is commonly called as rotary kiln, by processing material difference can be divided into cement kiln, chemical metallurgy kiln and
Limekiln.It is implemented recently as national environmental protection policy, resource Distursement, rotary kiln is gradually backward instead of facility, dirty
Contaminate earth kiln big, that energy consumption is high, shaft furnace.
Wherein chemical metallurgy rotary kiln can generate big amount temperature and be up to 300 DEG C ~ 400 DEG C during calcining metallurgy pelletizing
High-temperature gas, and existing high-temperature dust removal cloth bag, can long-term 260 DEG C of heatproof, 300 DEG C of instantaneous heatproof, not processed High Temperature Gas
Body is easy to the effect for making deduster lose dedusting.In addition, the metallurgical briquetting under normal temperature state is directly entered calcined by rotary kiln, meeting
Calcination temperature in rotary kiln is had a huge impact, power consumption is increased, increases production cost.
In order to solve the above problems existing in the present technology, the present invention has developed a kind of preheater, is forged using rotary kiln
The high-temperature gas generated is burnt, drying, heating metallurgical briquetting reduce rotary kiln energy consumption, while effectively reducing calcined by rotary kiln row
The gas temperature released enables deduster is permanently effective to play a role, plays the role of energy saving.
Summary of the invention
The object of the present invention is to provide a kind of revolution kiln tail vertical preheaters.
The present invention is achieved by the following technical solutions:

It communicates, the air-cooled bracket is fixed on the bottom of shell.
Further, the inner surface masonry of the shell has wearing-proof refractory material, for reinforcing the mechanical strength of shell,
And play heat-insulated effect.
The inner surface of the double-deck pyramid builds high-strength wearable refractory material, and outer surface builds light thermal insulation fire-resistant
Material.
There are gaps between orifice plate inside and outside the double-deck pyramid, after connecting with air-cooled bracket, form cooling air channel, are used for
It cools to the double-deck pyramid.
The discharging bin is the discharging bin of incline structure, and discharge end is connect with rotary kiln.
The discharging bin inner surface builds high-strength wearable refractory material.
The flue is ring smoke pipeline, is circumferentially positioned at hull outside, offers on the shell more
A gas outlet, multiple gas outlets are connected to flue respectively.
The blanking device is plough material scraper, is connect by transmission device with motor and speed reducer, when operation, by electricity
Machine makes rotating motion with speed reducer drive, and material is scraped.
The top of the pre-heating cabin is provided with maintenance door, is convenient to clean and overhauls.
The high-temperature gas that calcined by rotary kiln generates is entered enclosure interior by discharging bin by the present invention, by tracheae from bilayer
Pyramid enters pre-heating cabin, and the preheating zone formed to metallurgical briquetting preheats, and material is acted on from feeding warehouse via separated material cone, edge
After blanking channel enters pre-heating cabin preheating, rotary kiln is entered from discharging bin by blanking device；And high-temperature flue gas is by metallurgical briquetting
Preheating enters the flue of annular from gas outlet, into smoke duster after itself cooling；The double-deck rib of pre-heating cabin lower part
There are gaps between orifice plate inside and outside boring, and after connecting with air-cooled bracket, cooling air channel are formed, for cooling to the double-deck pyramid.
In conclusion the present invention preheats metallurgical briquetting using the high-temperature flue gas that rotary kiln generates, recycled to waste heat
While utilization, reach and extend flue gas dust collecting system service life, reduces energy consumption, reduce the purpose of pollution.
