Drilling fluid decanter centrifuge delivery to Thailand

⋅ Leave a Comment

DC Mud equipment company got an new order of decanter centrifuge from Thailand. Now the drilling fluid centrifuge wil delivering to the port.

Drilling mud decanter centrifuge is the fourth stage equipments for a drilling mud system.Drilling mud cleaning first stage uses drilling fluids shale shaker ,then second stage uses desander,third desilter,(now drilling mud cleaner is widely used to replace desander,desilter).

The high-speed, solids control decanter centrifuge removes ultra-fi ne drill solids of greater than 2 to 5 microns at an average process rate of approximately 20 percent of the mud pump flow rate, Anderson continued.

A centrifuge also can be used as a barite recovery system or dewatering system, a practice widely used in the oil and gas industry. The dewatering process, said Anderson, allows up to 100 percent removal of all suspended solids from the drilling fluid. The reclaimed water can be used to make up new mud for another job or as rig wash-down water.

Full hydraulic drive decanter centrifuge from DC Solid control

⋅ Leave a Comment

DC Machinery is a professional manufacturer of all kinds of decanter centrifuges. We can provide many different fields used centrifuges, such as oil and gas, food, chemical and mine well industry. Below is a introductuion of the full hydraulic drive decanter centrifuge.

A centrifuge with hydraulic drive is an interesting object from the fluid dynamics point of view. To achieve high efficiency, the hydraulic resistance of the inner, quickly rotating with the rotor, passages should be minimised.

At the same time the fluid should pass through an area far away from the axis of rotation, where the centrifugal force is greater. Nozzle efficiency is crucial. The air in the gap between the rotor and the centrifuge cover also moves, and the air friction makes a
significant contribution. Jets from the nozzles might break down into a fine spray and hit the rotor, slowing it down. Optimizing such a device is quite a challenging task, but this can, indeed, be done.

The hydraulic bowl and scroll drive system drives both the conveyor and bowl of a decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits.

The advantage of the full hydraulic drive centrifuge is for use in high temperature ambient for heavy mud with flexible bowl and differential speed. The compact one skid design makes it easier for rig up.

DCLW450-1000N Decante centrifuge got the the port to Azerbaijan

⋅ Leave a Comment

DC Solid control got a new order of DCLW450-1000N decanter centrifuge used in Azerbaijan drill site. Now the centrifuges have already got to the port and loading onto the trian to ship to the destination port.

DCLW series decanter centrifuge is horizontal spiral type which all model of decanting centrifuge that DC Solids manufactured. Decanter centrifuge is the fifth stage equipment in drilling mud system for solids control and mud cleaning.

centrifuges

The superiority of Decanting Centrifuge is embodied in the solids processing size. Decanter Centrifuge could remove the solid particles with size 2-7 microns by using the principle of centrifugal action in high RPM and it is an ideal choice for separating fine particles in drilling mud.

Application areas and features of DC Machinery decanter centrifuge

⋅ Leave a Comment

DC Machinery have been developed for many which support many domestic and foreign customer to process and separate the waste water and other plant liquid treatment and got good feedback as well .

Decanters are horizontal, solids-oriented, solid-wall scroll centrifuges. They are primarily used for the clarification of suspensions and sludge with relatively high solids concentrations,but also for the separation of liquids with simultaneous removal of solids.

DCGLW250-980N Decanter Centrifuge 01

Application areas include below fields:

the cleaning of wash water and the treatment of fruit and vegetables in the food industry
the recovery of animal and plant oils and fats
the production of herbal medicines, copper extraction
chemical extraction in the paper industry
the treatment of waste oil for power generation
waste water treatment in sewage treatment plants
use on oil platforms for the extraction of crude oil and so on

Features of DC Machinery

All parts coming into contact with the product are made of stainless steel.
3-phase AC motor for controlled torque starting via frequency converter
Approximately 80 to 90 % of the oil is recovered.
Low personnel costs due to continuous and automatic operation.
Highest g-force for higher solids output
Adjustable bowl speed via VFD
Automatic adjustment of differential speed via VFD
Two motor drive
Belts for both primary motor and secondary motor】

The Decanter centrifuge can be used for the pre-treatment for the algae biomass for the disk separator or tubular separator thus it effective higher the disk centrifuge or tubular separator capacity performance .

The decanter centrifuge is a horizontal centrifuge with continuous feeding and continuous discharging. The settling speed is determined by particle size, particle shape, difference in density between solids and liquids as well as their viscosity.

The drum of horizontal spiral decanter centrifuges

⋅ Leave a Comment

We all know, decanter centrifuge works principle is centrifugal force precipitate. And the main part to realize the separation is the drum. But do how much do you know the drum. Following is the description of the decanter centrifuges drum.

Drum diameter-D

In the condition of other ceteris paribus, the production capacity of centrifuge is directly proportional to D3. According the size of diameter, foreign centrifuge have already serialization. The diameter is stated by our country is 200, 450, 600, 800, 1000mm. The diameter of foreign centrifuge is 6, 8, 10, 16, 20, 25, 30, 40 in.

We know that when centrifugal force is equal, the drum diameter is bigger, the rotary speed is lower. The retention time of solid phase particles in drum is longer, it can make fine solid phase particles have full times to settle to the wall of drum in the function of centrifugal force and discharged through screw pusher.

drum

Drum length -L

Usually the drum length according to the diameter ratio to confirm, to the difficult separation material, the major axis ratio is 3-4. The length of drum is big, the volume of centrifuge setting pond is big, the retention time of solid phase is longer, so the separation effect is good. But the major axis ratio is limited by manufacturing technique and dynamic balance, so it can evaluate at well. To the difficult separation suspension liquid, the most reasonable method is improving the long diameter ratio in the condition of small diameter.

centrifuge

Drum shape

The drum shape has cone and tapered column the two basic structures. When drum length and diameter is fixed, the tapered column can provide bigger internal precipitation space to make the retention time of solid phase particles is longer in drum, the separation ability is stronger. Compared with cone drum, one is in the condition of treating is unchanged can keep the lower separation sizes; two is the throughput is bigger but the solid phase separation size is not changed. Because these reasons, drilling fluid treatment used centrifuge all use tapered column drum.
