Description
Technical field
Sludge of sewage treatment plant deep dehydrator is the utility model is related to, sludge is dehydrated again by depth, further drop
The moisture content of low sludge.By sludge by soft status modifying into hard solid shape state.And also can be applicable to other needs to be dehydrated
The field of product.
Background technology
Existing city domestic sewage treatment plant mixing sludge（Residual active sludge+Sludge from primary sedimentation tank）Dehydration technique field
Development, originate in nature desiccation dehydration develop into the major class of mechanical dehydration two.Natural desiccation system puts at sludge stand by graded sand
On the drying bed of stone place mat, by evaporating, permeating and the mode such as clear liquid overflow, dehydration is realized.Municipal sewage plant of China is equal
Sludge dewatering is carried out using plant equipment, thus is taken up an area less, compared with natural desiccation, stench influences also smaller.Mechanical dehydration
Species is a lot, can be divided into vacuum filtering and dewatering, filter-press dehydration and centrifugal dehydration three major types by dewatering Principle.
Sludge is placed on porous filter medium by vacuum filtering and dewatering system, vacuum is caused in medium opposite side, by sludge
In moisture " suck " by force, be allowed to separate with sludge so as to realize dehydration.
Sludge is placed on filter medium by filter-press dehydration system, is conveyed by screw rod pump liquid, and sludge is applied in sludge side
Plus-pressure, discharge pressure 10Kg/cm2Moisture is set to be allowed to separate with sludge, so as to realize dehydration by medium by force.
The official post that centrifugal dehydration system passes through moisture and the centrifugal force of mud granule is separated from each other so as to realize dehydration.More than
Several dehydration equipments all have the usage history of decades, but particular condition in use has very big difference.Twentieth century six or seven ten
The treatment plant that age builds, use vacuum filtering and dewatering machine mostly, but due to its moisture content of the cake compared with it is high, noise is big, occupation of land
Greatly, and its construction and performance in itself without larger improvement, since twentieth century eighties, seldom use.Plate compression takes off
Water dispenser moisture content of the cake is minimum, thus is using always.But this dewaterer is intermitten service, and efficiency is low, and troublesome in poeration, dimension
Shield amount is very big, so using not universal, is only used in the case where requiring that mud extraction moisture content is very low.Domestic newly-built place at present
Factory is managed, the overwhelming majority all uses band press filter dewatering machine, because this kind of dewaterer has mud extraction stabilization, continuity run, efficiency
The features such as height, less energy consumption, uncomplicated management control.Centrifugal dehydrator noise is big, high energy consumption, disposal ability are low, therefore makes in the past
With less.But since the mid-80, centrifugal dehydration technology has the general of significant progress, especially organic polymer coargulator
All over application, greatly improve centrifugal dehydrator disposal ability.
The dehydration of 2, city domestic sewages treatment plant mixing sludges is taken off after dosing is quenched by sludge dewatering equipment
Water.
1. plate compression sludge dewatering equipment：The intermittent operation of category, solid recovery rate is high, and pharmaceutical quantities are less, but unit sludge
Long operational time, sludge cake moisture content 75% are handled, fluid state sludge is conveyed by screw pump, discharge pressure 10Kg/cm2
2. belt press filtration sludge dewatering equipment：Belonging to continuity run, pharmaceutical quantities are higher, and unit sludge processing run time is short,
Sludge cake moisture content 85%.
3. Centrifugal sludge dehydration machine：Belong to continuity run, pharmaceutical quantities are few, and unit sludge processing run time is short, sludge
Cake moisture content 85%.
4. sieve bar sludge dewatering equipment：Belong to continuity run, pharmaceutical quantities are high, and unit sludge processing run time is short, sludge cake
Moisture content 85%, it is only applicable to crude fibre sludge dewatering.
In summary there is a general character, dehydrated sludge moisture content in the moisture percentage in sewage sludge of current sludge dewatering equipment processing
Exist in 75-85%, 4 liquid phases of these sludge water contents point in sludge, 1. intergranular free water, account for sludge water content 70% is left
It is right；2. some the small capillaries formed between mud granule, the water being filled with claim capillary water, account for 20% or so；3. particle
Absorption water be attracted to particle surface, account for 7% or so；4. in being present in inside mud granule or being referred to as in microbial cell
Portion's water, account for the 3% of sludge.
The content of the invention
This invention is by super high pressure hydraulic squeezing system, for also existing intergranular free liquid phase in dehydrated sludge
Moisture carries out deep dehydration, and 75-85% moisture is further dropped into 30-50% or so again.Remaining 20% or so capillary water, 7% left side
Right absorption water, 3%.Internal water, have to be by high cost drying technology processing could further reduce.
