Recently, GN Solids Control have finish 1 set waste treatment centrifuge

Centrifuge for separating finer solid particles and oil water, using a patented technologies and top-level materials and processes, imported bearings and components of internationally renowned brands to improve the stability of the equipment and prolong its service life.

For the GN solid control decanter centrifuges, the main drive motor is converted to stock through a differential drive centrifuge. back motors directly drive the auger and differential with its operating speed is fixed.

GN Solids Control is the first manufacturer of mud solid-control equipment in the country to pass the certification export standard qualification.,the centrifuge can work with other equipment together like shale shaker

Centrifuge use for different job like oil sludge treatment

1. Barite recovery centrifuge: The rotation speed is about 1800 RPM, the “G” value is about 700, the low-density separation point: 6-10 μm; the high-density separation point: 4-10 μm.

2. Large-capacity centrifuge: rotating speed is about 1900 ～ 2200RPM, “G” value is about 800, low-density separation point: 5 ～ 7μm (without weighting drilling fluid), used to exclude low-density solid phase;

3. High-speed centrifuge: The rotation speed is about 2500 ~ 3300RPM, the “G” value is about 1200 ~ 2100, and the low-density separation point: 2 ~ 5μm is mainly used to remove the low-density content of unweighted drilling fluid.

The suspension to be separated and the accelerating sedimentation agent are continuously transported into the centrifuge through the feed pipe, after being accelerated by the acceleration cone of the screw pusher, they enter the high-speed rotating centrifuge drum, and the suspension is An annular liquid flow is formed in the drum, and the solid particles rapidly settle to the inner wall of the drum under the action of centrifugal force. The differential speed of the centrifuge drum and the spiral produced by the differential drives the sediment to the drum cone by the spiral At the end of the dry discharge area, through the two-way squeezing of the screw thrust and the centrifugal component force, so that the sediment is further extruded and dehydrated, it is discharged from the slag discharge port of the small end of the drum. The depth of the liquid layer of the annular liquid flow can be adjusted by the overflow baffle at the big end of the drum to obtain different separation effects of sediment and clear liquid. The separated clear liquid is discharged through the overflow port of the centrifuge, the sediment and the separated liquid are collected into the respective collection bins in the casing, and finally discharged out of the machine under the action of gravity.

As a leading brand in the domestic solid-liquid separation equipment industry, GN Solids Control is constantly committed to providing customers with solid quality products with stable quality, superior performance and high economic efficiency. As far as decanter centrifuges are concerned, GN Solids Control has serialized the production models of centrifuges. From GNLW76 series decanter centrifuge with a 30-inch drum diameter, GNLW55 series decanter centrifuge with a 22-inch drum diameter, GNLW36 series decanter centrifuge with a 14-inch drum diameter to GNLW22 series decanter with a 9-inch drum diameter Centrifuges. The decanter centrifuge models in each series are divided into centrifuges with an aspect ratio of 3 and an aspect ratio of 4.2 according to the construction conditions. These various types of centrifuge models cover various solid-liquid separation conditions.

Decanter centrifuge and shale shaker is main equipment for drilling mud treatment

This month, GN Solids Control completed the delivery of two decanter centrifuges for an old customer in South America. The customer just ordered a batch of GN Solids Control products 9 months ago. After using the GN Solids Control products for a period of time, the customer was very satisfied and he immediately placed an order for the above centrifuge. South America is a very important region in GN Solids Control’s international market. At present, GN Solids Control has a very large number of GNLW22 series centrifuges serving various slurry processing sites in South America.

Generally speaking, the decanter centrifuge is mainly composed of several parts such as rotating drum, screw pusher, collection box, equipment base, main and auxiliary motors and electric control box. GN Solids Control can provide customers with two options of fixed speed centrifuge and variable frequency centrifuge, and can also choose the appropriate explosion-proof electric control box and explosion-proof motor according to different working conditions on the customer’s site.

The drum of GN Solids Control centrifuge is made of two-phase alloy stainless steel by centrifugal casting. The solid phase slag discharge port, drum scraper and side scraper are all made of cemented carbide material by precision metallurgy casting. Inside the drum, the blades of the screw propeller are made of carbide inserts, which are more wear-resistant and easier to replace. Not only do we strive for excellence in the materials of centrifuges, we also pay more attention to quality in terms of supporting brands. GN Solids Control centrifuge bearings use the international top brand-SKF bearings, electrical components are used Siemens, ABB and Schneider brands.

In view of the current huge demand for sludge treatment market, but the equipment manufacturers are mixed, and many customers have paid for the equipment with high prices and failed to achieve the expected treatment effect, our company has launched a set of sludge treatment equipment. Based on laboratory data, customers with sludge treatment needs can rent this set of pilot equipment to complete the calculation of various indicators, optimization of bottleneck process routes, implementation of various cost estimates, selection of chemicals, energy consumption estimates data collection. Based on these data, if you order the sludge treatment system, the customer can be targeted and purchase a system that meets their own on-site treatment.

The set of oil sludge treatment equipment includes the following parts:

1. Pretreatment screening module

The pretreatment screening module is a key module for removing large particles and debris from the mixed sludge. This module uses a high-frequency shale shaker to remove out large particles and debris larger than 100 mm. The mixed sludge from which large particles and debris have been removed will enter the mixing and stirring heating device for further medicinal heating and homogeneous stirring.

2. Solid-liquid separation module

After the heated and homogeneously stirred oil sludge mixture enters a special sludge centrifuge for settling separation, solids with a particle size greater than 2-5 microns can be separated.

3. Three separation modules for water, oil and slag

After separation by two solid-liquid separation modules, the mixed liquid phase contains a small amount of solid residue and an oil-water mixture. The three-phase disc centrifuge produced by GN Solids Control can separate this part of the mixture into three phases of oil, water and slag. After treatment, the solid phase oil content is 1-2%, the treated water can reach 500-1000PPM, and the treated oil water content is 2-3%.

If you are troubled now that you cannot find a reliable sludge treatment solution, please contact us. We will provide you with professional technical service support and perfect pre-sale and after-sales service support.
