Desanding or desilter plant is design for bored pile on construction with economy option and very compact design for small footprint. The desanding plant is design for flexible working and installation to suit bored pile, TBM or HDD mud recycling system.

Desander

The main components of all desanding plants are: Coarse screen for intercepting stones larger than 5 mm; Storage tank of the coarse screen; Cyclone with cyclone feeder pump for removing fine particles from the suspension; Dewatering screens for abstracting further water from the solids dis-charged by the cyclone.

desilter plant

Desanding plants are employed to remove soil particles in drilling mud and support slurry used in foundation engineering. They can be either water-bentonite, water- polymere, or water-cement and bentonite suspensions.

Deanter centrifuge is a very efficiency equipment for wasterwater process working progress. The centrifuge consists of a solid bowl, which rotates and contains the process. A screw conveyor, contained within the bowl, turns at a slightly different speed from the bowl.

DC Decanter centrifuge is an effective separation equipment which use centrifugal acceleration generated by high-speed rotation into the acceleration of gravity to shorten thousands of times of the settlement time of solid particles than in the gravity field. The solid particles are discharged from the drum through the screw conveyor continuously and without interruption.
decanter centrifuge

The material is conveyed to the screw discharge port through the feeding pipe and uniformly distributed in the drum through the spiral discharge port which is rotated at a high speed, and the main motor drives the drum to rotate at high speed through the belt to generate thousands of times of gravitational acceleration.

Rapidly settlement and accumulation of the solids particles in the inner wall of the drum, there is a relative movement of the screw conveyor to the drum, which will continuously push the sediment towards to outlet. The sediment is mostly dewatered under the combined action of the screw conveyor squeeze and drum dehydration. After the separation, the liquid is discharged freely through the liquid outlet point.

Features
1. Smaller Area Occupation: Centrifuge occupies only 1/5 of the other types of filter equipment with same process capacity.

2. High Automatic Degree: All process including startup, feeding, separation, discharge, washing, etc. are controlled by PLC with touch screen.

3. Safety Operation: Rotation parts equipped with safety cover. All processes are monitored by temperature, vibration, speed, electricity measurement. Ex-proof control panel and motor are applied.

4. Clean Operation Site: Well sealed operation, enable a clean and safe working site.

5. High Adaptability: Adjustable differential and speed to meet variable material and process request.

In order to fully understand how a decanter centrifuge operates, we must first define what a centrifuge does. In many industrial jobs, solid material often mixes with liquids, contaminating water supplies or turning mud into sludge.

centrifuges

A decanter centrifuge is useful in that it separates solids and liquids, and has become an essential component of water waste facilities and the chemical, oil, and food processing industries. Moreover, without a centrifuge, many of these companies would become so inefficient they could not function.

 

1) Inlet zone

The inlet zone accelerates the feed slurry up to the speed of the bowl. A properly engineered inlet zone keeps any degradation of the feed solids to a minimum as well as avoiding disturbance of the sediment in the bowl. A number of feed zone specifications are available for decanter centrifuges, each designed to ensure maximum performance in conjunction with a specific process.

2) Screw conveyor

The key to good decanter performance lies in the efficient, effective scrolling of the sedimented solids. The design of the screw conveyor is therefore crucial. You must have the expertise needed to match the demands involved in specific industrial processes with specific configurations of flight pitch, lead angle and differential speed, in order to secure the best possible results.

3) Solids Discharge Section

Depending on the application, the consistency of the separated solids can vary from a dry powder to a paste. The configuration of the discharge zone is therefore chosen to enable such “cakes” to exit as effectively as possible. Innovative designs enables erosion-prone components used in the solids discharge zone to be replaced on site at low cost and with a minimum of disturbance to production.

4) Liquid Discharge Section

In a two-phase decanter, the liquid level is regulated by dam plates. In a three-phase centrifuge when operating in a three-phase mode, each phase discharges over a set of dam plates into separate baffled compartments in the casing.

Horizontal decanter centrifuge has the advantages of good separation performance, well-adapted, can be automatic continuous operated, exercise intensively is small, small footprint and lower maintenance cost. So the decanter centrifuge had a rapidly development recent years, which can be widely used in industrial wastewater and municipal wastewater process field.

Mud gas separator is designed primarily for the removal of entrained gas, from the drilling fluid. The mud gas separator is designed in multiple capacities, to meet specific mud gas needs. But what should we pay attention to when use the mud gas separator.

SONY DSC

Two situations can cause mud gas separator blow-through.

1. Friction pressure of the gas venting through the vent line exceeds the mud-leg hydrostatic pressure, resulting in evacuation of fluid from the separator. Friction pressure of the mud through the mud return line is considered negligible because of its short length.

2. Vessel ID is too small, causing insufficient retention time for the gas to separate efficiently from the mud. This situation is commonly called insufficient separator cut.

To estimate a peak gas flow rate properly, we must consider a “typical” kick. The typical kick will depend on the well location, depth, type size, and component ratios of influx. Kick data should be based on previous offset well data and should be a realistic worst-case gas kick.

Usually, mud cleaner is the second stage equipment of whole solid control system. With the combination of a desander and desilter mounted over a powerful multi-functional shale shaker, DC Solid control’s line of mud cleaners offer both high performance and versatility for the operator.

The underflow screen is like having another shale shaker which receives the waste from the cyclone nozzle for additional processing. This is positioned so that the mud cleaner can recover more of the drilling mud. Our mud cleaner is the perfect piece of equipment in the second and third stage of the drilling mud treatment.

This integration of advanced equipment puts forth a unit that can handle large volumes of circulating fluids and is able to retain fluid integrity. Features such as our wedge-lock fastening system, mud bypass gate, and explosion proof enclosures all allow for ease of use.

Our pride is truly expressed in our work through our craftsmanship, research, design, and the overall practicality of our equipment.The mud cleaner is effective in processing both weighted and unweighted drilling mud during mud systems in removing and drying solids whilst retaining the expensive drilling liquid. Used correctly the drilling mud cleaner would lower both drilling-fluid and disposal costs.
