Product Description

Dewatering and thickening of municipal sewage sludge - Water and Wastewater - Sludge Management

Dewatering and Thickening of Municipal Sewage Sludge using the Decanter. Shenzhou has more than 50 years of experience in dewatering and thickening sewage slurry. We know the special requirements of sewage treatment plants and the water industry. As a result, we have developed a special decanter series especially for sewage treatment plants: the Shenzhou LW series.

Technology

SHENZHOU - Your Partner for Dewatering and Thickening of Sewage Sludge
The most important objective of dewatering is maximum volume reduction of the sewage slurry. This is because each tenth of a percent additional dry matter in the sludge delivers significant savings in sludge disposal.

For thickening, it is extraordinarily important to have a high separation degree and low polymer requirement. Both of these reduce the strain on the subsequent process, and thus improve the overall performance of the sewage treatment plant.

SHENZHOU has succeeded in building a particularly high-performance and efficient decanter in the LW series, at the same time as reducing energy consumption by up to 30%. The C series has a 10 to 20% greater throughflow rate with maximum dewatering result although it is no bigger in size, because of the larger sedimentation volume. This means sewage treatment plants reduce their investment costs by installing a smaller decanter, without losing any performance.

Worldwide, numerous decanters in the C series are in service in an extremely wide range of wastewater applications. Renowned reference customers - sewage treatment plants all over the world - are highly satisfied and have been able to reduce their operating costs significantly. You can benefit from our decades of experience in dewatering and thickening sewage slurry.

Advantages and features

Advantages of the LW Series in Dewatering and Thickening of Sewage Sludge
* Reducing the energy consumption by 30% compared to other decanters
* Saving fresh water - this water is now only required in processing the polymer solution
* Optimum price/performance ratio
* The acoustically insulated housing means that no further acoustic protection measures are required
* The machine is compact and easily accessible for maintenance work
* Minimum downtimes due to straightforward exchange of wearing parts on site

Scope of application:

Applications Overview
For dewatering and thickening sewage slurry, it is necessary for special properties of the bowl, gear unit and control system to be guaranteed. This is the only way to achieve maximum dewatering and thickening of the sewage slurry. The Shenzhou LW series is the new generation of environmental centrifuges which is characterised by familiar quality and reliability as well as an optimum price/performance ratio.

Main technical features

1. Industrial design

Whole machine set design follows concept of advanced industrial design,ensures stability,functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.


2. Effectively ease resonance during rotating of bi-rotor

When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.

3. Thoroughly eliminate phenomenon of liquid ring stalling

Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.
4. Unique technique adopt in main component work-blanks

The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.

5. Main bearing selection

We use origin bearings of international first-line brands such as SKF,FAG and so on.

6. Constant temperature detection

All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.

7. Inter-change ability

Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.

8. Simplyand safely in bearing disassemblement

One layer of oil film is injected into contact surfaces between bearing and work-piece by high-
pressure,during disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.
9.Main bearing lubrication system
There are two kinds of lubrication system for specific product models :
A thin oil lubrication
* Oil pump offers an uninterruptedly power to ensure oil works circularly;
* Jet oil lubrication constantly clean and lubricate bearings and reduce temperature;
* Oil filter system ensure lubricant’s cleanliness;
* Oil pressure energy storage system ensure lubrication pump offers an extra oil supply(the pressure is no less than 0.4Mpa) for 5-6 minutes,when power fails accidentally;
* Constant temperature system is available.


B grease lubrication
* Adopt a grease with properties of extreme pressure resistance ,oxidation resistance ,abrasion resistance,water scour
resistance,corrosion-proof and high temperature resistance.
* Optional automatic grease system fills grease on main bearing at designed hours and quantity.

10. Main bearing BH device (patent design)

There are two spare safe bearings at either end of main bearing.When machine works well,they keep certain clearance from bearing inside track to chief axis.When unexpected condition occurs,main bearing got damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance,safe bearings begin to work as main bearing Meanwhile,computer automatic control system would get a feedback of abnormal vibration value on bearing position immediately then activates emergency shutdown and goes a smooth shut down.This system protects machine free from damaging and ensure production safety.

11. GSRL feeding device (potent design)

New design of internal spiral core tube has got following achieves.Without reducing centrifugal acceleration,shorten triangle belt's traction time,reduce disorder of swirling flow and extend separation time.Meanwhile increases inner working pressure of centrifuge,and restrains liquid foaming.
