Description
Technical field
The invention belongs to sludge treatment device technical field, be specifically related to a kind of movable high-efficiency energy Treatment of Sludge
All-in-one.
Background technology
4 kinds of sludge dewatering equipments are mainly had: belt filter press, plate and frame filter press, centrifugal on prior art market
Dewaterer and spiral sludge dewatering machine, these 4 kinds of each have their own merits and demerits of sludge dewatering equipment, centrifugal dehydration
Machine utilizes centrifugal sedimentation principle, makes separation of solid and liquid, owing to not having filter screen, will not cause blocking, and belt pressure
Filter utilizes strainer to make separation of solid and liquid, for preventing strainer from blocking, needs water under high pressure constantly to wash away；Centrifuge is suitable for
The concentration of all kinds of mud and dehydration, band machine is also suitable multiple mud, but to residual active sludge and waterworks sludge
A large amount of medicament and dehydration difficulty need to be thrown；Centrifuge in dehydration when input concentration changes, rotary drum and spiral shell
The slip of rotation and moment of torsion can automatic tracking adjustment, operate so special messenger can not be set, and band filter is in dehydration
In when input concentration changes, belt speed, the rate of tension of band, chemical feeding quantity, flushing water pressure be both needed to adjust, behaviour
It is required higher；In centrifuge, tiny mud also can be separated from water, so the dosage of flocculant is relatively
Few, chemical feeding quantity when generally mixing with sludge dewatering is: 2～4kg/t [dry mud], the mud rate of recovery be 95% with
On, after dehydration, the moisture content of mud cake is about 65%-75%；And band filter can not knit get Tai Mi due to strainer,
For preventing tiny mud from slipping through the net, more flocculant need to be added so that mud forms bigger floc sedimentation, the most mixed
Chemical feeding quantity when closing sludge dewatering is more than 4kg/t [dry mud], and the mud rate of recovery is about 90%, mud cake after dehydration
Moisture content about 80%.The sludge dewatering power consumption of every cubic metre of centrifuge is 1.2kW/m3, during operation, noise is
76-80db, whole day 24h is run continuously, in addition to shutting down, is not required to rinse water in operation；And every cubic metre of band machine
Sludge dewatering power consumption is 0.8kW/m3, and during operation, noise is 70～75db, and filter cloth need to relax maintenance, typically
Only arrange two classes of operations every day, running needs constantly use high pressure water washing filter cloth；Centrifuge takes up room
Little, installation and debugging are simple, and corollary equipment only has dosing and input and output material conveyer, the hermetically sealed operation of complete machine, car
Between environment good；And band machine floor space is big, corollary equipment, in addition to dosing and input and output material conveyer, also needs to rinse
Pump, air compressor machine, sludge conditioner etc., complete machine sealing is poor, and high-pressure wash water smoke and stink pollute environment,
As bad in managed. mud can be caused to overflow.
