Drilling mud desander and desilter

Drilling mud Desander and desilter are solids control equipment with a set of hydrocyclones that separate sand and silt from the drilling mud used on drilling rigs. KOSUN Desander is used as the 2nd stage of solids control for drilling fluids, which makes separations between 45 and 75 μm. KOSUN Desilter is used as the 3rd stage of solids control for drilling mud, which makes separations between 15 and 45 μm.

There are some main difference between Drilling mud desander and desilter as following:

1.They are in the different solids control stage. Desander is the second stage solids control equipment, desilter is in the thrid stage;

2.They have different separation size. Desander make separations between 45 and 74 μm, desilter separate solids between 15 and 45 μm;

3.They have different capacity. Desander is 113 m³/h, desilter is 11 m³/h;

4.They have different hydrocyclone size. Desander uses 10″ and 12″ hydrocyclones, desilter uses 4″ hydrocyclone.

Desander is installed on top of the mud tank following shale shaker and vacuum degasser, but before the desilter. Desilter is installed on top of the mud tank following Desander. They also can be installed completely: in this case, they are installed on one deck shaker and called mud cleaner or mud conditioner. Desander removes the abrasive solids from drilling mud which cannot be removed by shale shakers.

The working principle of KOSUN linear motion shale shaker

KOSUN liner shale shaker is driven by a double vibration motor. When two vibration motors are synchronous and counter-rotating, the exciting force generated by the eccentric block cancels each other in the direction parallel to the motor axis and overlapped as a resultant force in the direction perpendicular to the motor axis. Therefore, the motion trajectory of the screen machine is a straight line.Its two motor shafts have an inclination relative to the screen surface. Under the combined force of excitation force and the material’s gravity force, the material will be thrown up and jump forward to make a straight movement on the screen surface, so as to achieve the purpose of screening and classifying the material.Can be used in the pipeline to achieve automation.It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance and completely closed structure without dust overflow.The highest mesh number is 325 mesh, which can screen out 7 materials with different particle size.

Kosun linear motion shale shaker uses the vibration motor to excite the vibration type, causes the material to be tossed on the screen net, at the same time makes the straight line movement in front, the material enters the material inlet of the screening machine evenly from the feeding machine.The upper and lower sieves of various specifications are produced through a multilayer screen,from respective outlet eduction.With low energy consumption, high output, simple structure, easy maintenance, closed structure, no dust overflow, automatic discharge, more suitable for assembly line operation.

Sludge dewatering and capacity reduction is not only an important part of sludge treatment.

Sludge dewatering and capacity reduction is not only an important part of sludge treatment, but also the most difficult part to realize. Domestic sewage treatment plants can only reduce the sludge moisture content to about 80% by mechanical dehydration, and a large amount of water brings great difficulties to the follow-up treatment of sludge. If the water is removed by means of heat evaporation, the huge energy consumption makes the sludge treatment cost high.

The reason why sludge dewatering and capacity reduction is difficult is that the sludge obtained in the sewage treatment process has high hydrophilicity, which makes it difficult for the water in the sludge to be liquid to achieve low-cost and efficient separation, resulting in the dewatering sludge difficult to achieve the economic and environmental unity of the treatment goal.

The sludge produced by sewage treatment has a high water content. Due to the combination of water and sludge particles, mechanical method to remove the sludge has a certain limit. The content of organic matter in the sludge, the proportion of ash, especially the addition of flocculant, has an important impact on the final solid content.Mud cake is still high in moisture content and fluid property, so it is difficult to dispose of it and the cost is still high, so it is necessary to further reduce the amount.At this point, in addition to natural air drying, only through the input of heat to form evaporation, can achieve a large reduction.The process of using heat to dry is called heat drying.

Trenchless construction is a horizontal drilling project used in construction or infrastructure projects.

Trenchless construction is a horizontal drilling project used in construction or infrastructure projects. In the process of trenchless construction, drilling mud is needed to ensure the performance of trenchless drill. To make drilling mud reusable and to reduce drilling costs, contractors often use mud recovery systems to recover drilling mud.

KOSUN has decades of experience in the design and manufacture of mud recovery systems, especially in trenchless projects with a variety of compact mud systems available to customers. According to users’ different requirements and site area limits, KOSUN can provide mud recovery devices with different configurations to meet the requirements of different working conditions. There are usually two types of mud purification systems for trenchless construction: one is the desander swirl purification system and the other is the self-supporting mud recovery system.

Sand removal swirling purification system covers a small area and is economical. The system is a combination of a cyclone and a shaker, which are mounted on a small collection tank. The desander swirl system is a two-stage separation device, whose function is to remove coarse particles in drilling mud. The desander swirl system is mainly used in engineering that can accept large diameter solid drilling mud, such as piling.

The mud recovery system independently developed by KOSUN can be divided into four separation systems: coarse cuttings separation, sand separation, mud separation and ultrafine solid separation. The higher mud recovery system has a larger mud tank with more room to store purified drilling mud and more crown space for more separation and purification equipment. When the tank surface space is enough, the customer can also choose a centrifuge to reduce the ultra-fine solid phase in the drilling mud, to avoid the enrichment of ultra-fine solid phase in the drilling mud.

The elevated diesel tank is installed with explosion-proof floating-ball level switch.

The elevated diesel tank is installed with explosion-proof floating-ball level switch; KOSUN 40+5m³ elevated diesel tank is the special-purpose oil tank to provide and store diesel for power machines (diesel engine, generator, etc.) of drilling crew. therefore the centrifugal oil pump can deliver the oil in oil storage tank to elevated oil tank automatically. In case of low oil level, the explosion-proof level switch opens, the oil pump starts automatically and oil transportation begins; in case of high oil level, the explosion-proof level switch closes, the oil pump closes automatically, and oil transportation ends. In order to prevent failure of explosion-proof level switch, the equipment is especially installed with oil return pipe. In such a way, the oil will not overflow from the tank even under failure of level switch.

When elevated oil tank is lifted up, the oil pressure rises. The oil in tank will be transported to equipment requiring diesel at drilling site from three channels through filter and flowmeter, and it can also flow back to the oil storage tank. The oil consumed by equipment can be read out from pointer of flowmeter.

After the elevated diesel tank is installed, check to ensure that all valves are in corresponding states. Park the refueling truck beside the oil tank, connect the outlet opening with oil feeding buffer tank or inlet opening before opening it and choose to start the 50CYZ-20 centrifugal oil pump; pay attention to the rotation direction of the oil pump. After opening or closing corresponding ball valves, and starting the oil pump, the oil flows into oil storage tank through filter, flowmeter, pipeline, ball valve and centrifugal oil pump. With liquid surface rising, the column of magnetic reversible level meter display changes from white to red. The junction of white and red colors indicates the liquid level of oil storage tank.
