Description
Technical field
The utility model belongs to the equipment of paper industry, relates to a kind of environment friendly and pollution-free drying section of paper machine that utilizes solar energy to make the energy specifically.
Background technology
Drying section of paper machine generally is meant part between paper machine squeezing unit and the coater unit and the part between coater unit and the press polish unit.According to its relative position difference in the whole piece production line of paper machine, it is dry to be divided into preceding drying, middle drying and back.For vat paper paper machine, the major diameter drying cylinder also belongs to Dryer Section of Paper Machine.The major function of Dryer Section of Paper Machine is to the wet web dehydration, guarantees that page reaches the mass dryness fraction of finished paper, and it is quantitatively consistent to adjust page vertical and horizontal moisture content simultaneously, guarantees page characteristic.
The wet web that comes out from the squeezing unit, because paper product and squeezing form is different, its mass dryness fraction is between 30%-47%.After wet web enters drying section,, evaporate big portion moisture, reach the mass dryness fraction requirement of finished paper about 96% through a series of heated drying cylinders.Evaporation process needs a large amount of heat energy, and these heat energy are supplied with vapor form usually.Drying section generally is that power consumption is maximum in the paper machine.Heat energy is delivered to paper web from steam, need sizable heat transfer area, so drying section is the hugest unit in the paper machine.
As Fig. 1, Fig. 2 and conventional paper machines drying section shown in Figure 3, this scheme is the version that present paper machine generally adopts.Mainly comprise Equipment Foundations 1, carrier rope transmission and tensioning apparatus 2, the thin steel band tensioning of annular and deviation correcting device 3, frame 4, vapour cover 5, the thin steel band 6 of annular, drying cylinder device 7; Also have transmission device shown in Figure 28, lubricating system 9 etc.For low speed paper machine, the true footpath of drying cylinder is generally 1.2m or 1.5m, and drying cylinder quantity is about 40.45 meters-60 meters of the entire length of drying section account for the 45%-48% of paper machine principal length.Article one, the gross weight of routine 3150 Dryer Section of Paper Machine is about 600 tons.Transmission power is 750KW, accounts for 1/4 of paper machine main body general power.13.5 meters of the device height of drying section generally are the highest in the paper machine main body, and corresponding factory building height is 20 meters.
Drying cylinder for high-speed paper machine 1.8m commonly used.Drying cylinder quantity is about 45, about 35 of vacuum reservoirs.Usually the entire length of drying section is 90 meters, accounts for 60% of paper machine principal length., a fabric width 5900mm, the gross weight of the high-speed paper machine drying section that the speed of a motor vehicle is 1600 meters/minute is about 2000 tons.Transmission power is 2650KW, accounts for 1/4 of paper machine main body general power.15 meters of the device height of drying section generally are the highest in the paper machine main body, and corresponding factory building height is 27 meters.
For vat paper machine, 3 meters-7 meters of drying cylinder diameters, 50 tons-120 tons of whole vat units, transmission power, 110kW-250kW, 10 meters of device height, corresponding factory building height is 17 meters.
