Recently, the oily sludge treatment system manufactured by GN Solids Control has been installed and debugged at a domestic customer and officially put into production, which has been highly praised by customers.


At present, due to various conditions such as different properties and working conditions of the oily sludge treatment system in China, few equipment manufacturers have consistent equipment. GN Solids Control has successfully developed a set of low-cost, high-quality system equipment through market exploration and technology research and development in recent years. The oily sludge is separated into multiple stages through this oily sludge treatment system, and finally the oily sludge is separated. Separated into oil, water, solid and other products. The separated oil can be directly sold to the refinery, and the water is repeatedly hot washed, and the oil content of the solid phase is controlled at about 1%-3%. The oily sludge reduction process is well completed.


This oily sludge treatment system is GNOST-05A, which processes 5 cubic meters of modulated sludge per hour. The overall system includes a feed module and a sludge vacuum pump for sludge transportation; pre-mixing module-2 sets of heating pre-mixing tanks; dosing module- The three-compartment automatic dosing system and separation module-a decanter centrifuge and a disc separator, can well complete the continuous and automated work from the feed end to the discharge end. The complete system can be operated by only 3 people. The energy consumption is low, which greatly saves the cost per ton of oil sludge treatment.

Recently, a set of sludge solidification equipment produced by our company GN Solids Control has been assembled and debugged, and will soon be sent to the geothermal well drilling construction site in a China important city to help the construction of the new area of ​​the motherland.

This set of curing equipment is mainly used for the curing of drilling cuttings, and its processing capacity can reach 15m³/h. This system is divided into two skid-mounted parts, namely the drill cuttings storage skid and the curing mixing skid. Drill cuttings storage hopper and solidification mixer are respectively installed on two skids, and the two devices are independent into skids, which is flexible in layout and convenient for shipment.

The system workflow of the sludge curing equipment produced by GN Solids Control is:

1. First, the drill cuttings storage funnel is used to store and receive drilling mud or waste, and then the material is transported to the solidification mixer at a certain flow rate through the screw conveyor at the bottom.

2. The chemical agent in the chemical additive storage box is sent to the curing mixer through a screw conveyor. In this system, the platform of the storage box is designed with a floating platform extending to both sides, which is conducive to the construction personnel to stack chemicals here. Additives for easy construction and efficient work.

3. The materials and chemical additives are fully mixed in the curing mixer, and the materials continue to move toward the outlet of the curing mixer. When the materials are delivered to the outlet, the curing process has been completed. The system also reserves a liquid phase addition port at the inlet of the curing mixer, which can add water, acid, alkali and other chemicals required for curing.

GN Solids Control sludge curing system is to fully mix the curing agent and the material in the curing mixer to complete the curing. During the operation of this system, the adding ratio of materials and curing agent can be set in advance. After the setting is completed, the system can be operated automatically, which greatly reduces labor costs.
