The composition of trenchless mud recovery system

The standard trenchless mud recovery system consists of mud recovery equipment, mud mixing equipment and mud collection tanks. Unlike the mud recovery device in the oil and gas drilling industry, trenchless drilling first discharges the mud back to the mud pit on the ground, and then uses a vertically installed submerged mud pump to transport the mud to the mud recovery system. Most drilling rigs will use a three-stage Purification system, shale shaker, sand removal, mud removal, and gradual removal of rock debris and solid waste. If there is a higher separation requirement, we will add a centrifuge to the system as a fourth-level processing equipment that can control the solid particle diameter of the slurry to 5-10 microns.

KOSUN has extensive field experience and a strong R&D and production team in the field of solids control systems such as trenchless mud recovery system. According to our country’s current municipal non-excavation technology and mud application status, combined with foreign advanced technology, the mud treatment equipment is optimized to ensure the completion of mud purification and recovery treatment while maximizing the protection of the original mud performance, saving construction costs, improving construction progress, and reducing Construction resistance and risk to achieve the best treatment effect.

Shale shaker, Rotary separator and Centrifuge in shield slurry separation system

In the construction process of the shield machine, the separation of slurry is an indispensable process. The separation efficiency also affects the tunneling efficiency of the shield machine. General slurry separation equipment includes shale shaker, rotary separators, centrifuges, filter presses, etc.

Centrifuge: The commonly used centrifuge is composed of two coaxial parts rotating around a static chamber. It is very effective for purifying bentonite mud, only keeping 6μm particles in the mud. Centrifuge is one of the very important solids control equipment.

Shale shaker: For the separation of materials of different particle sizes and gradations, the mud Shale shaker is the most basic solids control equipment. The Shale shaker is composed of one or more sieve plates, and the sieve hole of each sieve plate is gradually reduced. Shale shaker are generally used for sieving coarse materials, with holes as small as 60μm.

Rotary separator: The rotary separator is composed of a fixed cone. Its feed inlet is close to its shell. There is an upper overflow outlet at the top of the cone and a lower overflow outlet at the bottom. Larger speed is pumped into the rotating cone, causing it to produce a vortex, and the slurry enters the spiral in the cone. Large-sized and heavy-weight particles are separated by centrifugation at a certain speed, concentrated on the inner wall of the cone, and finally discharged through the bottom outlet; fine particles, retained in the muddy water, are discharged from the upper overflow through the spiral body. Rotary separators are widely used in surface separation stations. They can separate sand and sludge from waste mud water, and can even effectively separate 10μm particles.

Purpose and Classification of mud agitator

Mud agitator is one of the solid control equipment of drilling fluid tank, which is mainly used for mixing drilling fluid, preventing solid phase particles of drilling fluid from deposition in the tank circulation system, and making the circulating drilling fluid have stable performance and even mixing. The most commonly used forms of mud agitator in solid control equipment are as follows:

mud agitator
mud agitator

Mud agitator with gear transmission structure: the advantages are high transmission efficiency, but the disadvantages are large volume and inconvenient maintenance. Gear drive is also divided into direct drive and belt drive. The reducer adopts single-stage worm reducer with small structure size, light weight, stable transmission, low noise and large transmission power.

Worm gear transmission structure mud agitator: the current is still worm gear worm transmission. Worm gear and worm drive. Worm gear and worm drive is widely used in mud agitator because of its simple structure, high speed ratio and high reliability. The mud agitators imported from the United States are almost all worm gear direct drive. Worm gear and worm belt transmission structure, although its large volume, but has the characteristics of soft transmission, to protect the motor overload is very good.

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.

KOSUN is professional manufacturer for complete sets of drilling mud recycle system. The conventional equipment like shale shaker, mud cleaner, desander and desilter, vacuum degasser, decanter centrifuge, mud agitator, mud gun, centrifugal pump, screw pump, etc.

The treatment of sludge from industrial wastewater is still a difficult problem. The sludge composition of industrial wastewater is very complex, such as the sludge of dyeing wastewater, coking waste sludge, sludge containing various heavy, metal ions, have a considerable environmental hazard. At present, sludge treatment methods mainly include: medium temperature digestion, high temperature digestion, micro-additive method, chemical method, etc., but most of them cannot eradicate the pollutants in the sludge, especially the heavy metals, such as chromium, lead, and even gold. Sludge harmless treatment technology: through the harmless treatment process, decomposition of harmful substances.

In each processing link, it can be applied to the sludge harmless treatment technology, through the real harmless treatment, the sludge separation of metal, caused by bacteria, particulate matter, etc., effectively reduce the bacteria pollution index, and can quicken the pace of the degradation of toxic substances, within the rules, rapid processing of the pathogenic bacteria of sludge, thus achieve the goal of decomposition of sludge harmless, fully learn that in the process of sewage sludge to eliminate bacteria, not harmful to play advantage and function, so as to avoid secondary pollution in the process.

Slurry or Subway Muck treatment is a technology to separate solid particles from liquid in the mud, improve the porosity of pile foundation, reduce the amount of bentonite and reduce the cost of slurry production. It can control the quality of slurry water used for construction, realize the environmental protection transportation of slurry waste residue and discharge of slurry water, and meet the requirements of environmental protection construction site.
