2.GN High Speed Tubular Centrifuge features and Advantages

2.1GN High Speed Tubular Centrifuge is a kind of fine separation equipment, which is especially suitable for the solid-liquid separation of suspensions with thin concentration, fine particles and small solid-liquid weight difference, or liquid-liquid-solid separation. It is necessary equipment for Industries of pharmaceutical, food, chemical, and biological products, fermentation broth, beverages, blood products, etc. Its working principle is based on the centrifugal force to make the materials of different specific gravity receive different forces, so as to achieve the purpose of separation.

2.2 High Speed Tubular Centrifuges is artificial slag removal equipment, and the processing capacity is limited, so it is generally used for working conditions with low solid content and relatively small processing capacity.

GN 3 phase decanter centrifuge is mainly designed for Solid-liquid-liquid three-phase separation of materials. With our over 10 years of experience in the separation industry, it is the advanced type machine for 3 phase separation. It is designed for 24 hours continuous and smooth operation throughout the day. It is mainly composed of driving system, decanter bowl, screw conveyor inside the bowl, cover box, skid and VFD control panel. To ensure that the separation process can take place, the solid phase must be the specifically heaviest phase and the two liquid phases must have different densities. GN 3 phase decanter is widely used for oil , water, solids separation industry.

1.Indonesia emulsion and resin projectbackground and introduction

The dryer would be dewatering mixed raw wastewater from 2 sources: emulsion and resin production which has a sticky character. The TS is high (around 10%) but it is still flowable.VTS is 98% and 82%, which means the wastewater does not have much inorganic content. Overload and sludge blocking did not happen at the pilot test. Flocs were formed and sludge cake was produced. The filtrate of the emulsion waste was pinky (dirty) We assume that this could be improved by polymer dosing adjustment.

Treatment capacity requirements by this project: 30 kg-DS/h for Waste activated sludge /Raw wastewater at TS 1%

2. GN sludge dewatering screw press model GNDL-301 features

2.1 Introduction of GN screw press sludge dewatering machine

This is a kind of economic and environmental friendly sludge dewatering equipment. It is a new type of sludge extrusion dewatering equipment by using the principle of screw extrusion, through the strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between the floating ring and the fixed ring, to realize solid-liquid separation.

GN dewatering screw press is composed of fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering device, and liquid collecting tank. GN dewatering screw press is with automatic control technology, which can realize the flocculation fully automatic operation, and continuously complete the sludge thickening and squeezing, finally return or discharge the collected filtrate liquid.

GN screw press dewatering machine is widely used in sewage treatment projects of municipal, aquaculture, food, starch, oil, pharmaceutical, chemical, paper, leather and other industries

2.1Brief introduction

Sludge vacuum pump, also named as solids transfer pump. It is a type of pneumatic pump that sucks the material with vacuum produced by air operation, and then converts to positive pressure for discharging.Most of the solids, sludge and liquid could be transferred by using this pump. With special structure design of no rotating parts in the cavity, it can be used at tough environmental with high working performance and less maintenance. The pump can transfer material with high gravity and high density, solids content max.up to 80%. It has following features: the high efficiency venturi device can produce vacuum up to 25 inch HG(Mercury Column). This is equivalent to vacuum of 85Kpa to suck the material. The pump structure is simple and compact, almost none of wear parts. The transfer distance is up to 500-1000 meters.

2. Main separation treatment process of GN oil sludge treatment system

Main separation treatment equipment of the oil sludge treatment system is the three-phase decanter centrifuge GNLWS364-VFD. Its operation is based on the principle of sedimentation, that is, solid particles with specificliquid weight precipitate in a predetermined time. This principle can also be applied to two immiscible liquids with different specific gravity. When the material enters the high-speed rotating drum, the material rotates synchronously with the drum. Because of the different specific gravity, the centrifugal force is different. The solid particles with the larger specific gravity are subjected to the greatest centrifugal force, followed by the heavy phase liquid (such as water) and the light phase liquid (such as oil). So the centrifugal force is becoming less from outside to inside according to the magnitude of centrifugal force. A concentric solid layer and two liquid layers are formed. Solids are pushed out by the screw conveyor, and liquids are removed from theirrespective nozzles. Therefore, the application of three-phase decanter centrifuge can not only separate the solid in the material, but also separate the two-phase liquid with different specific gravity in the material, that is, Solid-liquid-liquid separation can be achieved.
