Paper mill sludge contains fiber, about 55%, by fermentation, filter press water into plastic, adhesion, moisture after drying 13% -15% "natural moisture>" use as fuels.
The type of sludge dryer .
1 A municipal wastewater treatment plant, treated water pressure filtration 45-55%, after a deep working organic fertilizer.
2, the paper mill sludge, treated water at around 60% after drying, can be used as fuel.
, Tanneries sludge treated water at around 60%, after drying, can be used as fuel.
4, West Pharmaceuticals sludge treated water in about 50% after drying, can be used as fuel, the calorific value of 7000 kcal.
5, sugar mill sludge is treated, the water is about 45%, after drying, deep plus organic fertilizer.
6, the food plant sludge treated, the water is about 45%, made after drying feed.
Second, the paper mill sludge drying process
1, the sludge into the drying site, the first accumulation of natural fermentation is 7 days, the moisture is evaporated naturally from 50% to 35% . 2, about 35% of the water sludge having beaten feeder, to become the 0-20 water mud pie evenly into the dryer.
3, 35% moisture, 0 to 20 cm of sludge into the dryer, at first into the 700 degree heat of the dryer area, instantaneous heating of the high
temperature zone so that the material surface curing, not sticking to the wall. Dryer speed 5 rev / min, to repeated collisions broken 100 times
the material in the drying cylinder, thus becomes the 0 to 5 cm of small groups into the medium temperature zone. Zone temperature to 500 to
400 degrees of moisture in the material in this large number of volatile repeated Yang scattering material, particle size of from 0 to 2.5 cm into t
he low temperature zone. The temperature of the low temperature region of 400 to 300 degrees, the material to the feed inlet with a speed of
0.6 m / min, and after 30 minutes of drying Yang Caesar. Carom material size 0 to 1.5mm. About 16% of the water, the discharge end of a row in
the air volume 25000m ³ powerful exhaust fan under cloud. Material outlet temperature of about 100 degrees. Granularity as to 8mm, about 16%
moisture, conveyor material from the spout, the material was cooled after 30 minutes, the moisture of 12-13%,
Third, the cost
55% of the initial water in the fiber feed, end after discharging cooling water 12-13%, in the drying process to be 5000 kcal per ton of coal 17kg 5000 kcal coal as fuel, 1 kg of coal can be reduced to 1 tonne of material. percent of the water. That is, 1 kg
5000 calories of coal to make 1 ton of material to reduce the moisture, plus the wind can also reduce the water content of the sludge. Raw materials 35% moisture down
to 16% moisture in the combustion start working properly after just 17kg coal. (Theory 18kg).
