Selection Decanter Centrifuge Model According Process

In the production process, there are different process requirements such as dehydration, clarification, concentration, classification and separation. The essence of dehydration and clarification is to separate the solid and liquid in the suspension from each other. Dehydration is to remove the liquid phase in the solid phase, and clarification is to remove the solid phase in the liquid phase.(Decanter Centrifuge)

Decanter Centrifuge-kosun — Decanter Centrifuge

A large amount of liquid phase, a small amount of solid phase, and the particle size of solid phase is very small (1o μ M) or amorphous mycelium, horizontal screw disc or tubular centrifuge can be selected. If the solid content is less than 1% and the particle size is less than 5rm, the tube type or zigzag type manual slag discharge can be used to separate vanadium. If solid content ≤ 3%, particle size < 5 μ m. Disc piston slag separator can be selected. The separation factor of tubular separator is high (f ≥ 1000, the separable particle size is about 0.5m. The finer particles have higher clarity, but the single processing capacity is small.

KOSUN is a professional manufacturer of Decanter Centrifuge for about 30 years, and we can supply capability of manufacturing decanter with bowl size from 220mm to 760mm.

KOSUN Construction Mud Solid-liquid Separation Equipment

Linear Dewatering Shale Shaker– Construction Mud Solid-liquid Separation Equipment
Linear Dewatering Shale Shaker is specially designed to separate larger and coarser solid particles. The construction mud enters the shale shaker through the feeding funnel, and separates large-diameter solids such as large stones. The screen on this shale shaker has a longer lifespan than traditional woven screens.
Double-layer mud Shale Shaker
After being screened by the Linear Dewatering Shale Shaker, the liquid phase enters the Double-layer mud Shale Shaker again. The Double-layer mud Shale Shaker is a two-stage separation. It first enters the bottom layer of the Double-layer mud Shale Shaker. The mesh number of the bottom layer is smaller, and the coarse particles are further screened. The mesh number of the upper screen is higher, and the liquid phase passing through the bottom screen enters the upper screen again, and the effect is better.
Mud cleaner
The liquid phase screened by the Double-layer mud Shale Shaker is pumped to the mud cleaner. The mud cleaner consists of two 10-inch desander cyclones and 12 4-inch desander cyclones plus a shale shaker. The liquid phase first passes through the desander cyclone, and then enters the desliming cyclone. After separation by the mud cleaner, the material conditions for entering the centrifuge are reached.
Decanter centrifuge
The separation capacity of the decanter centrifuge is more refined. In order to ensure a good use effect, the requirements for the materials entering the centrifuge are relatively strict, so the front coarse screen, fine screen and cleaner are processed. The centrifuge can separate solid particles above 2-5um. After the centrifuge treatment, it meets the customer’s requirements.
Flocculation dosing system
The flocculation dosing system is the icing on the cake. When the level required by the customer is higher, the flocculation dosing system can make the centrifuge more effective.

Centrifuges in the drilling solids control system and mud zero discharge system

The centrifuge is a common equipment in the drilling solids control system and the mud zero discharge system, so what is the difference between the centrifuges in the drilling solids control system and the mud zero discharge system?

Centrifuges in Drilling Solids Control Systems

The centrifuge in the drilling solids control system generally adopts medium and low speed centrifuges. Since the drilling solids control system adopts multi-stage solids control equipment, when the drilling fluid is filtered and separated from the mud shaker to the true remover to the sand and mud integrated machine after three-stage filtration and separation, the particle size of the mud particles has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuges have been able to meet the needs of slurry pulping.

Centrifuge in Mud Zero Discharge System

The centrifuge in Mud Zero Discharge System generally adopts a high-speed centrifuge or a frequency conversion centrifuge, which is a high-end centrifuge. The Mud Zero Discharge System is composed of a drill cuttings dryer and a high-speed variable frequency centrifuge. The Mud Zero Discharge System is located at the end of the solids control system and is used to process the drilling cuttings tailings processed by the solids control system, so the proportion of drilling cuttings tailings is very large, the solid particle size is large; because the centrifuge is to undertake the mud processed by the drilling cuttings dryer, the particle size in the mud screened by the drilling cuttings dryer is very large, and the requirements for the centrifuge are very high. Therefore, it is more appropriate to use a high-speed variable frequency centrifuge.

Waterway and river sludge dredging and dewatering treatment equipment

1) Excavator dredging equipment: first use the pump to drain the water in the river to the other side, and after it is drained, the excavator enters the river or waterway for dredging construction. Excavator dredging equipment is a relatively common dredging construction machinery and equipment. The advantages of using excavators for river channel dredging are that the operation is convenient and simple, the construction cost is low, and it is suitable for operations with dry and hard mud and shallow river depth construction.

2) Desilting equipment of vertical mud pump mud conveying system: the main components of vertical mud pump mud conveying system are: mud pump, floating body, mud conveying hard pipe, rubber hose, etc. Its working principle process: the pressure generated by the water flow through the centrifugal pump, through the water pipe and the water gun, spews a dense high-pressure water column for cutting and crushing, forming the flow state of the mixed liquid of mud and mud blocks. Pumps and mud pipes are sucked to the sludge dump. The mud pump dredging is not only easy to operate, but also conducive to improving water quality and protecting the ecological environment. Its main operating range is suitable for operation in mountainous and hilly areas, and also suitable for dredging of river channels with small water surface.

3) Cutter suction vessel dredging equipment: the main components of cutter suction vessel are mud pump and suction device structure. The pump sucks the sludge from the suction pipe, and the sludge discharge pipe discharges the sludge to the river bank or directly into the mud barge for transportation to a certain place for temporary storage and then for sludge dewatering treatment. The cutter suction boat is mainly aimed at the bottom of the river where the sludge is soft in the river channel.

4) Screw stacker sludge dewatering equipment: The working principle of this equipment is that after the sludge is first concentrated by gravity, the screw stacker is transported to the dewatering section, and gradually becomes smaller with the filter seam and screw pitch during the working process. , and the great internal pressure generated by the resistance of the pressing plate, the capacity is continuously reduced, thus truly realizing the purpose of dehydration. The screw stacker has a wide range of applications and is suitable for the advantages of high and low concentration sludge dewatering.

5) Decanter centrifuge sludge dewatering equipment: The process flow of the dewatering equipment can be roughly divided into: the pump lifts the sludge and then performs a screening pretreatment system, and then adds an appropriate amount of flocculant to the sludge to fully stir, and finally uses Centrifuges perform deep dehydration procedures. The dry and solid mud cake after sludge dewatering can be transported to other places where it needs to be reused, which truly achieves the double harvest of environmental protection, energy saving and economic value. The advantages of this equipment are convenient and simple operation, large processing energy, small processing site occupation, high degree of automation, and low noise due to low vibration.

6) Diaphragm filter press sludge dewatering equipment: The sludge dewatering process of this equipment can be roughly divided into: the sludge lifted by the pump enters the primary sedimentation tank and the secondary sedimentation tank, and then continues to enter the grid and concentration tank Then, a certain amount of flocculant is added for complete stirring and mixing, and then it enters the homogenization tank. Finally, it is highly dehydrated by the filter press, and the treated filter cake realizes the resource utilization of external transportation. The advantages of diaphragm filter press are high compression pressure, large processing capacity, low moisture content of filter cake, stable equipment performance, low failure rate and high degree of automation.

7).Geotechnical pipe belt sludge dewatering equipment: The process flow is roughly as follows: first, the sludge is filled into the geotechnical pipe belt for many times through a mud pump, and an appropriate amount of flocculant is added to promote the solid-liquid dewatering effect of the sludge. The combination of the filter part of the pipe bag and the two power factors of the liquid pressure will quickly and efficiently dehydrate the added dewatering agent sludge, and the solid part of the dewatered sludge will be trapped in the geotechnical pipe belt, and the percolating water will be discharged to the river after treatment. in the waterway or directly into the municipal sewage pipe. The solid portion trapped in the pipe can be reused in other industries for efficient resource utilization. Its advantages are good anti-wear performance, good UV resistance and water permeability. The geotechnical tube bag has a strong accommodation capacity for sludge, a large volume adjustment range, and a civilized and hygienic working environment. It is suitable for projects with large amount of sludge dewatering, large construction site and relatively loose construction period.

The key to the production of aviation kerosene storage tanks

How to improve the reliability of aviation kerosene storage tanks? Aviation kerosene storage tanks are important fuel supply equipment for aviation oil companies. The importance of the manufacturing and production of aviation kerosene storage tanks directly determines the reliability of the transportation of aviation kerosene and the high-end quality of aviation kerosene.

The reliability of the use of aviation kerosene storage tanks requires strict control over the entire process of drawing design and manufacturing of aviation kerosene storage tanks. In view of the difficulties in the production and production of kerosene tanks, it is necessary to optimize the treatment plan and the specific operations of on-site production.

To improve the reliability of aviation kerosene storage tanks, attention should be paid to the following three difficult issues:

1) Difficulties in the production of the conical bottom of aviation kerosene storage tanks: There are certain difficulties in the production of the conical bottom of aviation kerosene storage tanks. The design and production of the slope of the tank bottom is a difficult point. To achieve a satisfactory degree of coordination, detailed analysis needs to be done in advance, the designed slope must be adapted to meet the specific use standards, and the bottom of the kerosene storage tank must have good integrity and the bottom plate can be coordinated with the tank body. Unite. The welding treatment of the conical bottom of the aviation kerosene storage tank is also very important. The number of welds should be reduced to a minimum, and the problem of welding deformation should be controlled.

2) Difficulties in installing the upper and lower end walls of aviation kerosene storage tanks: The difficulty in installing the upper and lower end walls of aviation kerosene storage tanks lies in the corresponding stress control, which requires strict control from the error aspect to avoid tank deformation caused by corresponding stress concentration. . The verticality, perimeter, and levelness of the upper and lower end wall panels of aviation kerosene storage tanks also need to be strictly controlled and corrected to ensure better forming integrity of the kerosene storage tank.

3) Difficulties in welding requirements for aviation kerosene storage tanks: In the manufacturing process of aviation kerosene storage tanks, the welding requirements for kerosene storage tanks are very high. The welding operation of kerosene storage tanks is actually closely related and mutually influencing with the shape requirements of aviation kerosene storage tanks. During the welding process, it is necessary to control weld defects caused by stress concentration. For the problem of welding seam defects, it is necessary to operate from the main aspect of welding scientific and reasonable design.

The above has explained the key points of the production and production of aviation kerosene tanks through three difficult aspects. To provide high-quality aviation kerosene receiving and dispatching operations, we must first handle the reasonable layout during the design stage of the aviation kerosene storage tank, and rationally arrange the steel plates and welds. At the location point, during the production process, the operation must be strictly abided by the regulations. After such a serious and strict production process, the reliability of the aviation kerosene storage tank can be improved.
