Object contains the venomous injurants such as the nutriments such as a large amount of nitrogen, phosphorus and organic matter, viral micro-organisms, parasitic ovum, heavy metal
Matter, if serious harm will be generated to environment without disposition is effectively treated.How sludge is dealt carefully with, makes its minimizing, steady
Fixedization, innoxious, recycling, become problem anxious to be resolved in environmental pollution improvement.
Traditional sludge treating method mainly includes landfill, burning and land use, since moisture percentage in sewage sludge is higher, volume
It is huge, all there are problems in practical applications.Moisture percentage in sewage sludge is reduced, sludge drying is realized, improves its calorific value, becomes solution
The certainly key of these problems.
Practice have shown that the moisture content of mechanical dehydration sludge is still up to 80% or so, to reach the deep dehydration to sludge, than
More economical method is to carry out heat drying to sludge, that is, utilizes most of wet part in thermal energy removal sludge.In heat drying equipment, circle
Heat transfer area is big, mixing effect is good, efficient promotion moisture evaporates and removes, device structure is compact, sludge because having for disk desiccation machine
The advantages that moisture content wide adaptability, becomes the sludge drying stand-alone device being most widely used.Disk desiccation machine by changing indirectly
Heat realizes the evaporation of moisture in sludge, and the exhaust steam after desiccation still contains gasification latent heat, but the residual steam one in practical application
As directly outlet or be condensed, secondary recovery and utilization are not carried out to the energy, bring the loss and waste of the energy.
In addition, certain " stagnant zone " can be generated in mud drying process, i.e., when moisture percentage in sewage sludge is down to the area of 45%-65%
Between when, since sludge is adhered to heat exchange contact surface, lead to the reduction of desiccation machine heat transfer coefficient, drying efficiency decline is viscous across this
Dead zone needs greater energy consumption.
