Recently, the GN Solids Control R & D team has successfully upgraded the original mud recovery system-upgraded shield mud separation system for several months in response to the market demand for shields, pipe jacking and piling, and first received orders for the domestic market. The system has been successfully introduced to the international market and will be issued to foreign customers in the near future. Orders for this batch of shield mud separation systems have come from several engineering construction units in Saudi Arabia, Singapore, Myanmar and India. In addition to bored pile engineering, this system with a small footprint, low cost, and significant processing effect can also be widely used in tunnel shield and pipe jacking projects and non-excavation directional crossing projects.

This set of mud separation system is mainly composed of three solid-liquid separation equipments such as vibrating screen, sand removing cyclone and mud removing cyclone. Its working principle is as follows:

1. A slurry supply pump pumps engineering slurry from a mud pit to a Shale shaker for preliminary solid phase separation to remove large particles of sand and gravel. It should be noted that the slurry supply pump can be purchased separately by the customer or selected by our company for the customer. Match.

2. After the slurry has undergone preliminary solid-liquid separation through a shale shaker, the slurry supply pump in the system is pressurized to supply the sand removal cyclone. After the high-speed cyclone separation, the grit component with a particle diameter greater than 40 microns is removed, the fine sediment is separated into the transfer tank, and then fed to the desilting cyclone by a slurry pump. The desilter cyclone will be more than 20 microns The particles are separated, and the slurry below 20 microns is returned to the storage tank, and re-proportioned and pumped to the construction machinery for recycling.

3. This system can also be equipped with a high-speed centrifugal dewatering centrifuge, which can separate 5-20 micron fine particles in the mud to ensure the performance of the mud.

The upgraded GN Solids Control shield mud separation system can be divided into three types according to different processing capacity: GNTBM-240M, GNTBM-360M and GNTBM-500M. The corresponding processing capacity is 240 m3 / h, 360 m3 / h, and 500 m3 / h. hour.

Considering the transportation costs of foreign customers and customers in remote areas in China, the above piling mud purification system does not have a standard storage mud tank.

The sewage treatment plant will reuse or discharge the sewage sent through the necessary treatment means to meet the national water quality control standards. From the perspective of sewage treatment, pollutants can be divided into suspended solid particles, organic pollutants, toxic substances, polluted organisms and polluted nutrients.

Treatment methods can be divided into physical treatment methods, biological treatment methods, sludge disposal and chemical treatment methods generated from sewage treatment according to the type of water quality. The physical treatment method is a method for separating and removing pollutants in sewage by using physical action. Common methods are sieve retention, gravity separation, centrifugation and so on. The decanter centrifuge plays an important role in the processing equipment of centrifugal separation.

Sludge dewatering is the main obstacle to river dredging projects. Equipped with a Shale Shaker, a sand remover, and a desilting dredging system, which can remove sludge above 25 microns, but fine particles below 25 microns cannot be processed. At this time, a centrifuge is needed. The GN Solids Control centrifuge can separate fine particles above 5 microns without adding polymers and relying only on mechanical separation. Through the addition of drug flocculation technology, the centrifuge and Dewatering unit can be used together to achieve zero emissions.

Sewage is pretreated by processing equipment such as grids, sand settling tanks, sedimentation tanks, etc. At this time, fine solid particles still exist in the sewage. The decanter centrifuge can use the quality difference between the fine particles (minimum 2-5 microns can be separated) and the liquid to mechanically complete the problems that the previous processing equipment cannot handle. GN Solids Control decanter centrifuge adopts centrifugal cast two-way stainless steel 2304 or 2205. The internal pusher adopts tungsten carbide alloy sheet inlaid protection for more durable and durable, these features provide protection to improve the life of the centrifuge.

What difference speed (pushing speed) can be used for sewage treatment?

1) First, the high differential speed (pushing speed) completely mixes liquid and solids; the entire mud centrifuge will work like a mixing mixer instead of an effective solid-liquid separation device.

2) Secondly, chemicals are usually added to the separated wastewater. High differential speed (pushing speed) will cause some medicine to be lost in the liquid outlet.

3) In addition, if chemicals are added to the wastewater before entering the centrifuge, it will generate foam in the centrifuge.

Therefore, if your centrifuge has experienced the above problems, you may need to consider reducing the differential speed (feed speed).

After the decanter centrifuge processes the sewage, it will then pass through activated sludge treatment system and tertiary treatment of biological denitrification and phosphorus removal, coagulation sedimentation filtration, activated carbon adsorption, etc., and finally become reclaimed water, which is usually called water.

 With the increasing improvement of horizontal directional crossing technology and the increasingly strict requirements of the state on environmental protection policies, the horizontal directional crossing solid control system also has higher requirements. Horizontal directional crossing of solid control equipment is mainly reflected in the obstacles such as oil and gas pipelines crossing rivers, lakes, transportation trunks, and railway junctions. There are also a variety of separation techniques for the principle and technical method of horizontally directional crossing solid control to control the solid particles in the mud.

Environmental protection is a sensitive topic for us for a long time. Because the horizontal directional drilling mud contains many harmful substances and is of high value, the recovery of mud in the horizontal directional crossing system is the primary requirement of the owner for the construction. Construction units of horizontal directional crossing have purchased mud solid phase control equipment one after another to separate the waste solid phase and reuse it, turning waste into treasure, and have achieved considerable economic benefits. At the same time, it has also promoted the development of domestic horizontal directional through mud solid control system.

Horizontal directional crossing has not been developed in China or even the world for a long time. It does not have its own perfect system in drilling and mud. At present, it is largely absorbed and applied after the improvement of the oilfield process system. At the domestic level, the solid-phase separation method of directional through mud is somewhat similar to that of oil fields. There are mainly three methods of dilution, sedimentation and mechanical removal. GN Solids Control analyzes the difference between horizontal directional crossing mud and petroleum drilling mud, conducts detailed analysis and conducts a lot of field research and experiments. The successful R & D is in addition to the horizontal directional crossing solid control system specially designed for horizontal directional through mud. The main equipment includes shale shaker, centrifuge, and supporting pump system

At present, the horizontal directional through mud solid control and recovery system used in China is divided into domestic and imported, and the imports are mainly small, and they are matched with the rig when imported. The domestic ones are mainly large-scale and are prepared according to user needs.

According to different construction environments, the types and sizes of particles that need to be removed or suppressed, and the quality requirements of muds that need to be maintained are different. GN Solids Control can configure a reasonable and reliable solid control system for customers according to the actual working environment needs and combined with the company’s previous successful cases.

The GN Solids Control mud purification system is widely used in solid-liquid separation conditions for various mud-water wastes. The waste mixture is separated to form useful materials. GN Solids Control recently received a customer from North America whose main business is the use of vacuum trucks to collect various waste mud and solid waste at drilling or construction sites. This customer asked GN Solids Control to design and manufacture a mud-water separation system that meets his site conditions.

The picture above shows the core equipment in the mud cleaning system designed and manufactured after we inspected and combined with the actual production environment of the customer. This system fully considers the site area, the feeding method and the convenience of the processing procedure.

In this mud-water separation system, fine particle solids are separated by a shale shaker device with a fine screen. For solids smaller than 100 microns, use a hydrocyclone to separate them. At the beginning of the design, this system was fully integrated with human factors engineering. The drilling fluid shaker and cyclone part were covered by enclosures. Not only protect working parts and prevent mud from spraying to pollute equipment, but also fully consider and ensure the safety and convenience of operators.

For ultra-fine particulate solids in mud, the system will use a decanter centrifuge system and a chemical dosing system for separation.

The purpose of the mud cleaning system is to separate solid waste from the mud as much as possible. Aiming at the mud produced by the hydraulic excavation project, the mud cleaning system can recycle the beneficial liquid-phase mud, and the separated gravel and sand can be used to make building materials.

We also have a large number of related cases and products for customers to choose from. If you have related requirements, please feel free to contact GN Solids Control.
