Technical field
The present invention relates to a kind of sludge drying treatment equipment, more particularly to a kind of sludge high-drying integrating device.
Background technology
As the requirement to environment improves in China, China increasingly payes attention to the treatment to sewage, increases rapidly in recent years
Sewage disposal requirement will produce substantial amounts of biological sludge, and how can deal carefully with these sludge, as in sewage disposal
Environmental problem urgently to be resolved hurrily.
Sludge is condensed through various modes are cementing by the suspended solid in water, loosely organized, in irregular shape, its
Specific surface area is high with porosity, and water content is high, and dehydration property is poor.There is branch and the network structure of similar appearance in appearance.It is dirty
The moisture percentage in sewage sludge that water treatment plant produces may be up to 99%, quality and bulky, be unfavorable for transporting and process disposing, it is necessary to drop
Low its moisture content.
Moisture percentage in sewage sludge is down to 80% from 95%, and sludge volume reduces 75%, and 50% is down to from 80%, and volume will again reduce 60%.
When the moisture content of sludge is higher, his calorific value is lower, and when moisture content is less than 50%, sludge is just adapted to burn.And contain in sludge
There are a large amount of microbial cells and organic colloidal matter, mechanical dehydration is difficult.The moisture content of sludge is restriction sludge treatment and utilization
Key issue, and the desiccation link of sludge be specific resistance to filtration system power consumption key link.
The heat and mass of sludge heat drying is mainly manifested in following two process：
One is evaporation process：The moisture vaporization of surface of material, water vapor pressure of the steam partial pressure higher than surface of material in medium,
Therefore moisture moves into medium from surface of material；
Two is diffusion process：Diffusion process is and vaporizes closely related mass transport process.When surface of material moisture is evaporated, thing
Expect surface humidity be less than material interior humidity, at this time, it may be necessary to the motive force of heat by moisture from interior shifting to surface.
Above-mentioned two process continuously alternately, substantially reflects dry mechanism.It can thus be seen that dry
Dry is that, by surface water vapor, moisture enters medium and internal water spreads, and the two are mutually auxiliary from material interior shifting to outside for moisture
The process coordinated is completed.
