Technical field
The invention belongs to sludge drying processing technology fields, and in particular to a kind of sludge drying machine.
Background technique
With the continuous quickening and the development of modernization industry of urbanization process.The annual whole world can generate enormous amount
All kinds of municipal sludges and industrial sludge.Sludge is the high solid organic castoff of a kind of moisture content, even by
Its moisture content of the pretreated sludge such as concentration, centrifugation is also 80% or so.For this purpose, people are sought for certain suitable technique side
Formula is to be effectively treated above-mentioned sludge.Sludge drying technique is a kind of common to can effectively reduce moisture percentage in sewage sludge in order to its continuation
The technology of subsequent processing is carried out, specific is to heat in the equipment specially designed to sludge, evaporates the mistake of wherein moisture
Journey.It can not only effectively realize the removal effect for " Free water " in sludge, at the same also to " Interstitial Water " therein,
" surface-bonded water " or even " internal junction Heshui " can all play rapid evaporation purpose.Since the technology can be according to subsequent processing process
Requirement, by sludge drying to specified moisture content, therefore it is widely used in the processing of existing sludge drying.
The processing of sludge generally comprises the drying and other treatment and terminal disposition of front end, such as Sludge landfill requirement of terminal disposal technology
Moisture content 60% is hereinafter, sludge incineration requires moisture content 40% or so.Therefore no matter which kind of terminal disposal technology, technology are used
Key point be all the moisture in how simple, efficient, the energy-efficient removing sludge in front end so that raw material adapt to it is final
Disposition requires.
Sludge drying mainly uses heat drying technology at present, i.e., carries out the processing method of deep dehydration to sludge with heat source,
It can make the significant volume reduction of sludge, and volume can reduce 4-5 times, and product is stable, odorless, without causal organism, after drying and other treatment dirt
Mud product purpose is more, may be used as fertilizer, soil conditioner, alternative energy source etc..Conventional sludge drying machine needs to consume a large amount of
The energy, in mud drying process, the damp-heat air temperature of generation is higher, and the energy of contained recoverable is more.But because
The moisture that damp-heat air contains is more, and the effect for being used directly to dry sludge is poor, and temperature is also not achieved and is used directly to do
The standard of dry sludge, so the reusable thermal energy in this part is not recycled.
