Waste Oil Decanter Centrifuge

GN 3 phase decanter centrifuge named oil Decanter centrifuge, it is mainly designed for Solid-liquid-liquid three-phase separation of materials. With our over 16 years of experience in the separation industry, it is the most advanced type equipment for 3 phase separation.

The smallest model of decanter centrifuge is 224FT, it come with 2 motors, one 11KW Main Motor and one 5.5KW back drive motors,  the bowl diameter of 224 models is 220mm, the bowl length is 924mm, Bowl L/D Ration is 4.2, Max G Force is 3080G, The typical bowl speed is 4800PRM, and the typical G force is 2838G.

Three-phase Oil Decanter Centrifuge show great superiority in the treatment of triple mud, as they not only separate out the solids in the mud, but also the dirty oil in the mud, which is incomparable to other separation methods. At the same time, the water and oil content of the dry sludge after treatment by the three-phase decanter centrifuge is reduced to varying degrees.

In the three-phase Oil Decanter Centrifuge, the main motor drives the drum to rotate at full speed and the material is continuously introduced into the spiral by the feed tube and evenly distributed to the spiral discharge port.

GN sludge vacuum pump

GN sludge vacuum pump named solids vacuum pump, it can do some dry and transfer job, it’s 100% air driving, need to connect to a air compressor for work.

There are 3 model due to the handling capacity, GNSP-10B, GNSP-20B and GNSP-40B, the max handling capacity is respective 10M3/h, 20M3/H and 40M3/h. The request of vacuum degree of all of them is 85Kpa/25 inch HG(Mercury Column), and the max sunction distance is 50M. The max solid size is 75mm for GNSP-40B, and max particle size is 50MM for both of GNSP-10B and GNSP-20B. There are some discrepancy regarding to air demand, 17M3/min(600CFM) for GNSP-40B, 8M3/min(280CFM) for GNSP-20B, 4.3M3/min(150CFM) for GNSP-10B.

The vacuum pump equip with the quick connector at inlet/outlet pipe, which is equipped with barb to connect with suction and discharge hose.

GN vacuum pump is 100% pneumatic pump with no electric component, it can used in the explosive environments and also pass ATEX certification. A typical application of vacuum pump is to transfer the oil sludge to the oil sludge system as a conveying equipment.

8 Sets Inclined Plate Clarifier and 6 Sets Decanter Centrifuge for mud treatment6 Sets Decanter Centrifuge for mud treatment

Recently GN separation completed 8 sets inclined plate clarifier and 6 sets decanter centrifuge, 8 sets inclined plate clarifier will be sent to overseas customers for industrical sludge treatment, 6 sets decanter centrifuge will be sent to the domestic major drilling company for driiling mud treatment.

In this order, the overseas customer choose the model of GNIPC-25A for inclined plate clarifier, GN IPC design incorporates inclined plate settling surfaces pitched at a 55° angle from the horizontal with uniform plate spacing. Due to plate angle the solids slide down the plates into the sludge hopper below the plate pack. Herewith pls find the following photo

Chemical like polymer pretreatment often improve solids removal effeciencies. The use of chemical flocculants with GNPIC inclined plate clarifier is depend on the efficiency of the system and so on.

GN decanter centrifuge

GN dewatering decanter centrifuge is T series decanter centrifuge with beach angle of 8.5 degrees. T series decanter centrifuge is generally used dewatering and thickening purpose.

Sludge Decanter Centrifuge are used for sludge dewatering without chemical conditioning, but when the sludge is conditioned with polymeric electrolytes, the solids retention rate and the quality of the liquid after centrifugation are significantly improved. The centrifuged liquid slopes back to the sludge thickener or initial settling tank. The water content of the sludge cake is approximately 70-80%. The sludge centrifugal dewatering centrifuge requires a smaller site area than a vacuum filter with the same production capacity and has lower capital costs.

The advance of the decanter centrifuge

1、Continuous automatic operation

Decanter centrifugal dewatering from pumping out sludge, injecting medicine, discharging sludge cake are automatically controlled, through the electronic control cabinet, and into the sludge pumps, dosing pumps, etc., linkage, do not need personnel to operate the equipment, the operation will not be clogging, filtering away from the bias or other phenomena affecting the safety of the process, the daily maintenance of maintenance simple, 24 hours can be continuous unmanned operation. The sludge dewatering continuous full-automatic operation is realised in the real sense.

2、Saving project investment

The decanter centrifugal dewatering machine itself has the function of sludge thickening, and it can directly deal with aerobic sludge in the aeration tank without thickening and storage unit, which reduces the overall space occupied by the sewage treatment facility and the construction cost.

3、Machine body is light and durable

Decanter centrifuge due to the direct use of mechanical centrifugal separation dewatering, without the need for large-scale body, so the machine is designed to be quite lightweight; almost all the body is made of carbon steel or stainless steel, with a long service life and durability.
