Description
Technical field
The utility model relates to drying, modified device, and specifically, the utility model is the device that a kind of coal by low-cost drying and waterproofing of brown improves the coal-fired thermal efficiency.
Background technology
China's lignite resource is abundant, and mining conditions is good.According to incompletely statistics, the open-air brown coal ore reserves in the whole nation reaches tens billion of tons.
Brown coal and bituminous coal this, difference in quality is very big, mainly is that the brown coal water content is big, calorific value is low.Some mining area brown coal water content have had a strong impact on the coal-fired thermal efficiency up to more than 40%.As certain mining area high quality brown coal butt caloric value is 5600 kilocalorie/kilograms, and after comprising full moisture content, uses calorific value of coal and just be reduced to 3600 kilocalories.
Because brown coal are the extremely strong material of hygroscopicity, dry back is met water and is then absorbed moisture content rapidly.The general distance of Coal Transport is far away, water content means that greatly then freight increases, and its storage, transportation very easily be subjected to influences such as sleet, and traditional technology can only solve dry problem, can't low cost allow brown coal become hydrophobicity, cause the efficient utilization of brown coal that realization is not arranged so far from water imbibition.
The utility model content
The purpose of this utility model provides the device that a kind of brown coal drying waterproof improves the coal-fired thermal efficiency, and this lapping device has low cost, speed is fast, output is big, the advantage of serialization production, wide adaptability.
The device that coal by low-cost drying and waterproofing of brown of the present invention improves the coal-fired thermal efficiency has thoroughly solved the problem that coal by low-cost drying and waterproofing of brown improves efficiency of combustion, and the present invention realizes by following method:
The screw rod that has screw channel rotates in machine barrel, brown coal and water-repelling agent are added in the screw rod drying machine, fall into the gap between screw rod and the barrel, because the rotation of screw rod, drive material rotates thereupon, simultaneously because screw channel changes the squeezing action of bringing to the promotion of material with by spiral groove depth, material is subjected to strong shearing force and pressure in whole machine barrel inside, produce violent friction with screw rod and machine barrel, generate a large amount of heat, so material just in whole machine barrel space by rapid draing simultaneously also by the upgrading fragmentation, the wet minute steam that produces discharged by the steam vent of opening on machine barrel, drying effect and raising output in order to increase material is added corresponding heating facility in whole machine barrel outside simultaneously.The material that is dried at last is discharged from complete equipment under the conveying effect of screw rod, enter subsequent handling, realizes the continuous drying hydrophobically modified to material.
, characteristics such as output big, serialization production fast by the speed that the dry modification of above screw rod has are not difficult to find out that the screw rod drying is a kind of very desirable dry modified method.
In order to realize above-mentioned utility model purpose, the utility model by the following technical solutions:
One, device is made up of parts such as the machine barrel of barrel, screw rod, band heater, discharging adjusting device, discharging openings;
Two, brown coal and water-repelling agent add complete equipment by hopper, travel forward along screw rod, are transformed into the product after the dry modification, discharge from discharging opening at last;
Two, by violent friction between material, screw rod, the machine barrel three and the heater on the machine barrel material is heated, remove its wet branch and modification;
Three, isolated wet minute steam is discharged by the steam vent of opening on barrel wall from material.
It is characterized in that:
A, the strong shearing that utilizes screw rod and conveying effect are carried out dry modification institutional operation to material;
B, utilize frictional heat and external heater to carry out the heating of material simultaneously;
C, material are driven the motion that realizes machine intimate by screw rod;
D, parametrization design, complete equipment, especially screw rod can adopt different parameters with the production needs according to the difference of actual material properties;
E, simple in equipment, applied widely, can serialization production, invest low, production efficiency is high.
A kind of coal by low-cost drying and waterproofing of brown improves the device of the coal-fired thermal efficiency, is made up of machine barrel, discharging adjusting device, the discharging opening of barrel, screw rod, band heater; Screw rod is built in the machine barrel of concentric band heater, and the discharging adjusting device is connected with the machine barrel level of band heater successively with discharging opening, and barrel is arranged on the machine barrel of band heater, is positioned at screw front end portion.
Described screw rod can be single screw rod, twin-screw or the multiscrew that has interior or outer heater.
Described screw rod can be to move in the same way or perikinetic single screw rod, twin-screw or multiscrew.
Heater in the machine barrel of described band heater can be, but be not limited to: resistance heated, infrared heating, electromagnetism heating, hot oil heater.
The utlity model has following advantage:
Owing to adopted technique scheme, the present invention compared with existing device, technical matters have following advantage and effect:
A, screw rod drying, volume is little, and simple in equipment, low cost of manufacture realize drying, modification, broken integrated simultaneously, need the occasion effect of broken material huge again in the dry modification of needs;
B, dual-heated mode have guaranteed the rapid draing of material and the comprehensive utilization of the energy;
C, realize the dry of material and carry dual-use function, the very big simplification that brings equipment by screw rod;
D, screw rod adopt the parametrization design, can adopt different parameters flexibly at material of different nature, improve the flexibility and the applicability of complete equipment greatly;
E, this equipment adopt the motion mode of material and screw rod follow-up can serialization production; Simultaneously simple structure, number of devices less, can realize that whole a large amount of industrialization duplicates, market prospects are very wide.
