Background technique
Recently as urbanization and industrialized development, municipal wastewater treating capacity is sharply increased, and causing to generate largely has
Sludge to further dispose.Since moisture percentage in sewage sludge is 80% or so, such high-moisture percentage is to the transport of sludge or other
Terminal processes are all unfavorable, aqueous when sludge is as cement filler material if its moisture content of sludge incineration processing requirement is not higher than 40%
Rate is not higher than 20% etc., so carrying out pretreatment to sludge, dry to reach acceptable moisture content necessary.
The drying process of current sludge mainstream is direct drying technique and indirectly drying technology.And main drying means
Have: tunnel drying and box-type drying, rotary drying, belt drying, horizontal Paddle Drying, fluidized bed drying, solar energy drying
Deng.The shortcomings that carriage-type drying, to be that corresponding operation complicated for operation is costly and its structure is complicated corresponding fake it is also more expensive.Tunnel
Road is dry to be disadvantageous in that material cannot disperse, drying time is long, energy consumption is serious.For traditional belt drying skill
Art, the direct contacting material progress heat and mass of dried medium, and material are moved together with conveyer belt, opposite between material particles
Position is relatively fixed, and internal moisture is not easy to be discharged for the sludge for having stickiness, can only increase belt length and improve dried medium
Temperature.Although and having lifting blade for traditional drum-type drying but consuming energy seriously, and inside rotating cylinder because volume is excessive
Space utilization rate is low.There are many structure and form of horizontal Paddle dryer, feature also it is many such as: compact-sized, land occupation face
Product is small, heat utilization ratio is high etc..The partial size of desiccation particle and size distribution are affected to result in fluidized bed drying, partial size mistake
Small perhaps size distribution is wide can generate viscous motion area and particle temperature it is higher when agglomeration or reunion easy to form.The sun
Although still its dispersibility is greatly, calorific value is low, equipment investment is big and temperature rise is small, has indirect for the dry clean hygiene cleaning of energy
And unstability.
