Description
Technical field
The present invention relates to drying unit field, specially a kind of novel natural gas multi-drum drier.
Background technology
Multi-drum drier is widely used in building materials, metallurgy, chemical industry, cement industry, for drying slag lime stone, coal dust, ore deposit
The materials such as slag, clay.
The primary structure of existing multi-drum drier is：Mainly include the more cylinders of combined type, transmission device, heating plant,
The more cylinders of combined type include the outer barrel of different-diameter, middle cylinder, inner cylinder from big to small, and suit forms with one heart；Transmission device mainly includes
Motor and wheel holding mechanism；Heating plant includes hot-blast stove, blower fan.Operation principle is：Wet stock enters revolution by feeding device and rolled
The internal layer of cylinder, realize that following current is dried, material is constantly taken up under the flight of internal layer, the helically travelling that is scattered realizes heat exchange,
The other end that material is moved to internal layer enters middle level, carries out adverse current drying, and material is constantly raised into being in into two repeatedly in middle level
The traveling mode of backward is walked, material had both fully absorbed the heat that internal layer roller distributes in middle level, absorbed the heat of middle level roller again
Amount, while drying time is extended again, material reaches optimum drying state herein.Material row is fallen into outer to the middle level other end
Layer, material rectangular multiloop mode in outer layer roller advances, and reaches the material of the drying effect quick row under hot blast effect
Enter to discharge roller, the wet stock for being not reaching to drying effect is unable to Fast marching because of deadweight, and material enters in this rectangle flight
Row is fully dried, and thus completes drying purpose.The heating plant wherein used is mainly that hot-blast stove produces hot blast, and heat is mainly warm
It is delivered in dryer, material is dried by heat transfer, thermal convection current, heat radiation.
But there is problems with three-cylinder drier of the prior art when in use：1st, drying plant at this stage is mostly
Electric oven is dry or is dried by hot-blast stove, and hot-blast stove provides hot blast using burning coal, and the structure of drying oven is mostly
It is made up of combustion chamber and blower fan, this hot blast mode energy loss is big, seriously pollutes environment, and in all parts of the country at present because environment is dirty
Dye problem, the use of various coal-burning boilers is limited comprehensively；With electrical heating, cost is higher, and is mostly by burning generation ability
Hair point is carried out, then produces heat energy by electric power and is dried, the step of adding energy conversion, is easily made in transfer process
Into energy loss, therefore requirement when prior art can not meet drying well, therefore there is an urgent need to dryer is carried out
Improvement；2nd, existing drying unit uses hot-air seasoning, and the more tube structures of combined type of dryer are set, and easily cause gas not
Circulation, drying effect weaken；The heat exchange of material and high-temperature hot-air is uneven, influences drying effect.Therefore, it is badly in need of a kind of new day
Right gas multi-drum drier.
The content of the invention
To solve the above problems, the invention discloses a kind of novel natural gas multi-drum drier.Existing more are dried
The equipment of machine is improved, and using origin of heat of the natural gas as burning, reduces sulfur dioxide, an oxygen caused by coal burning
Change the discharge of the toxic and harmful gas such as carbon, reduce the cost of exhaust-gas treatment, environmental protection；Increase the heat transfer area in drying,
Improve rate of drying；Heat caused by effective recycling combustion of natural gas, avoids the waste of heat.
In order to reach object above, the present invention provides following technical scheme：
A kind of novel natural gas multi-drum drier, including compound cylinder, transmission device, natural gas combustion device, guiding device, it is multiple

Discharge end communicated with the feed end of outer barrel, the discharge end of outer barrel connection discharge barrel, the other end connection of the radiating tube
Feeding cylinder, the hot gas of the interior discharge of radiating tube are dried from feeding cylinder into inner cylinder to material；The inner cylinder center is provided with
Guiding device, the guiding device include antipriming pipe, the piece of breaing up being arranged on the outside of antipriming pipe, the other end position of the radiating tube
In in antipriming pipe.
Further, it is provided with temperature detector on the inside of the outer barrel.Temperature detector can monitor the temperature in dryer at any time
Degree, avoids temperature is too high from being impacted to material, while when temperature is relatively low, raises temperature.
Further, it is provided with heat-insulation layer on the outside of the radiating tube.Heat-insulation layer is made using insulation material, effectively avoids heat
Amount is scattered and disappeared.
Further, the piece of breaing up includes breaing up piece so that antipriming pipe die center is symmetrically arranged, and the piece of breaing up is consolidated
Surely it is welded on the outside of antipriming pipe.
Further, the novel natural gas multi-drum drier is additionally provided with moistureproof window, and the moistureproof window installs blast pipe, institute
State blast pipe connection exhaust blower.Hydrofuge machine can effectively discharge the moisture in dryer.
The combustor connection natural gas of natural gas combustion device, hot gas caused by combustion of natural gas are connected by combustion chamber
Radiating tube be transported in the inner cylinder of compound cylinder, realize the drying to wet stock, natural gas combustion device is used to provide hot gas,
Compared with prior art, environmental protection, economize on resources, rationally make use of hot gas, avoid the waste of hot gas.Transmission device is used for multiple
The rotation of formula cylinder, wet stock are entered in inner cylinder from feeding cylinder, realize that following current is dried, the lifting blade through inner cylinder is kicked up, constantly
Take up, the helically travelling that is scattered realizes heat exchange, material is moved to the discharge end of inner cylinder, enters middle cylinder, then proceed into
Row adverse current is dried, and material is constantly raised into, material repeatedly in middle cylinder had both fully absorbed the heat that inner cylinder distributes in middle cylinder, inhaled again
The heat of cylinder in receipts, while heat exchange is carried out with hot gas, while drying time is extended again, material reaches optimum drying shape herein
State, then therefrom the discharge end of cylinder enters outer barrel, continues to carry out heat transfer with hot gas, and fully absorb the heat of middle cylinder.Heat
Gas is uniformly dispersed to the inside of compound cylinder, and hot gas carries out thermal convection current with the air in compound cylinder so that whole compound
Temperature rise in cylinder, material heating surface area is uniform, not only increases the contact area of material and hot-air, improves drying
Speed, while contact of the material with hot-air is uniform so that drying materials are uniform, will not cause to dry irregular.Moisture is by air draft
Outside machine discharge machine, reach drying effect.Material after the completion of drying is discharged from discharge barrel.Piece of breaing up on guiding device can be favourable
In breaing up wet stock, avoid wet stock into sticking together, into the material to stick together inside be difficult to touch hot gas, drying effect is reduced, therefore is beaten
Discrete piece can effectively solve this problem.More pores protection radiating tube of guiding device simultaneously, avoids wet stock from blocking radiating tube
Gas outlet.Whole device is rational in infrastructure, efficiency high, noise are low, safe and reliable.
In summary, it is an advantage of the invention that：The equipment of existing multi-drum drier is improved, made using natural gas
For the origin of heat of burning, the discharge of the toxic and harmful gas such as sulfur dioxide, carbon monoxide caused by coal burning is reduced, is reduced
The cost of exhaust-gas treatment, environmental protection；Increase the heat transfer area in drying, improve rate of drying；It is effective to recycle day
Heat caused by right gas burning, avoids the waste of heat.
