Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but is not limiting as protection domain of the present utility model.
nullThis utility model solves its technical problem and be the technical scheme is that a kind of winnofil produces flue residue heat pre-drying device，It includes cylinder 14 and bottom bracket 9 thereof、Central shaft 4 and installation claw bar 6 on center shaft、Basin 5、Actuating device 8、Flue gas introducing cylinder 2、Flue gas discharges cylinder 3 and steam discharges cylinder 10，It is provided with central shaft 4 in described cylinder 14 and claw bar 6 on center shaft is installed，If claw bar 6 is provided with dry harrowing leaf，In cylinder 14, central shaft 4 suit is provided with six basins 5，Including three shallow bids and the deep bid of three band centre bores 12，Shallow bid and deep bid uniform intervals the most successively is installed，Each basin 5 each correspondence above is provided with claw bar 6，Flue cavity 11 and gas approach 17 and exhanst gas outlet 18 is set in each basin 5，Some spoilers 19 arranged in a crossed manner in flue cavity 11，Gas approach 17 is disposed adjacent with exhanst gas outlet 18，And it is welded with flue gas division board 16 in flue cavity 11 between the two；Described actuating device 8 is made up of motor and reductor, is arranged on below cylinder 14, is connected with the central shaft 4 in cylinder 14；Described cylinder 14 top center is provided with bucket-shaped material inlet 1, bottom is provided with discharge port 7, and flue cavity 11 outer rim of each basin 5 is provided with service hatch 15；Described cylinder 14 side is provided with the steam through with it and discharges cylinder 10；Described flue gas introducing cylinder 2 and flue gas are discharged cylinder 3 and are arranged on cylinder 14 side, and they are connected with the flue cavity 11 of exhanst gas outlet 18 with each basin 5 by gas approach 17 respectively.
nullThe winnofil that this utility model embodiment is provided produces flue residue heat pre-drying device in use，This device is arranged on the front end of main drying machine，Actuating device 8 drives central shaft 4 and installation claw bar 6 to be on center shaft rotated in a clockwise direction，Calcium carbonate wet feed is fallen the basin 5 of the superiors from the bucket-shaped material inlet in the top of this device 1，Calcium carbonate wet feed is along with the rotation of basin 5 upper fabric target bar 6，From top to bottom fall into deep bid from shallow bid outer rim，Deep bid falls into shallow bid from centre bore 12，In the process，The flue gas produced by heat conducting oil boiler flue is by air-introduced machine active force，Removing dust device enters the flue cavity 11 of each basin 5 from flue gas introducing cylinder 2 by gas approach 17，Spoiler 19 arranged in a crossed manner in flue cavity 11 makes the S-shaped flowing of flue gas，After and after material absorbs heat，Flue gas is discharged cylinder 3 top by exhanst gas outlet 18 from flue gas and is expelled to device with air-introduced machine air-flow，Each basin 5 calcium carbonate wet feed above is by the heat of the flue gas in flue cavity 11，Moisture is made to evaporate under the rotation of material target bar 6，Steam is discharged cylinder 10 by the steam through with cylinder 14 and is discharged，Calcium carbonate wet feed is finally released in bottom discharge openings 7，Then pre-dried wet feed is sent directly into main drying machine.
When calcium carbonate wet feed enters from this device top, being dropped to 28%-30% to water content during discharge port by original 30%-35%, wet feed temperature increases to 90 DEG C.Pre-heating dryer heat balance: calcium carbonate wet feed ordinary temperature 40 DEG C, the material of discharge port is heated to 90 DEG C, gas phase drop temperature 145 DEG C, day predrying calcium carbonate wet feed 300 tons.Calculate:
Heat Q1=300 × 10 brought into by material3× 2.01 × 40=24.12 × 106kJ
Dried material takes heat Q2=280 × 10 out of3× 0.84 × 90=21.16 × 106kJ；
Steam takes heat Q3=300 × 10 out of3× [2675.5+2.01 (150-100)]=83.28 × 106kJ；
Heat gain from appliance and equipment Q4 is calculated as roughly the 20% of total amount of heat；
UTILIZATION OF VESIDUAL HEAT IN amount Q5=1.2 (Q2+Q3-Q1)=1.2 (21.16+83.28-24.12) × 106=96.3 × 106kJ。
Raw coal calorific value be 25100 Kilojoule/kilogram, then weight G=96.3 × 10 of economizing on coal6÷ 25100=3836kg.Calculating by moisture of filter cake content 30%, 300 tons of filter cakes produce calcium carbonate finished products 210 tons, calculate with this, and ton product is economized on coal 18kg, signature coal 13kg.
