Super filter press

How to dewater the sludge like this?

 image003.jpg      image004 拷贝.jpg

GS series Super-pressure sludge filter press arrives. Sludge with more than 90% moisture after this series product handled can become to mud cake with 30%-50% moisture. It can solve the problem that organic sludge is difficult to be effectively used.

Working Principle

Super-pressure sludge  filter press adopts the technology of high pressure feeding by hydraulic piston pump and super high pressure squeeze. When feeding finished, hydraulic piston pump presses directly filter plate for squeezing. Owing to sludge feeding and squeezing capacity high, it can be efficiently and deeply dewatered. Super-pressure filter press clamp system and high pressure squeeze system use same one hydraulic system, compared to filter press, it saves high pressure water squeezing system. 

Advantage :

1. High filter plate strength, long use life 

Super-pressure sludge filter press frame adopts high strength low alloy steel, it can bear thousands tons work pressure. Its key parts filter plate adopt high strength anticorrosive alloy steel, can meet more than 100kg/cm2 high pressure requirement. Filter plate using life can reach 10 years. It reduce the operation and maintenance costs of equipment.
 

2. High filtration pressure , the production efficiency is greatly improved

 Super-pressure sludge filter press feeding material pressure is high to 2MPa ,press pressure high to 60-110kg/cm2 . This pressure is 6-10 times of common diaphragm filter press. Cause of super high pressure, moisture in sludge will be detachment rapidly. Working cycle time will be 2-4 times shorter than diaphragm filter press.
 

3. Low moisture content of Caky sludge

Same working condition, sludge after high pressure press, caky sludge moisture content can be controlled at 15%-50%, its average moisture content is 15%-40% lower than common filter press. This result comes from the good Cell Wall Broken Technology. And Super-pressure sludge  filter press adopts a pressure which is higher than a critical value of water broken cell wall pressure.
 

4. High automation

Super-pressure sludge filter press use high automation. Electronic control system adopt PLC programmable controller and touch panel operation panel. Material will be fed, pressed, unloaded automatically. And press also will be clean itself by press air not water during working process. It saves the common filter press manual unloading and artificial cloth washing procedure, saving time and labor. One person can operate 2 sets of equipment at the same time. 

5. Low operation cost 

Because of above characteristics, this equipment operation costs is very low. And cause if adopt critical high pressure makes space water detachment and cell wall rupture more easier. After test, its operation cost is only equal to 50% of  cost of common filter press
 

6.Multi design style 

We supply Super-pressure sludge filter press both in fixed and mobile condition to meet customer’s different demand.
