500 HDD Mud Circulation System: High - Capacity Solution for Construction Projects
HDD Mud Recycling Systems( is short for horizontal directional drilling) is applied to urban municipal construction and electrified pipe network transformation. Communication cable laying and the big and small rivers, lake and the horizontal directional crossing construction when the building cannot be demolished, especially in the environmental protection and municipal pipe network expansion project and the horizontal directional crossing construction of large pipeline crossing river project.
In the second and third stages, the desander and desilter respectively play pivotal roles. The desander is designed to eliminate medium - sized sand particles, while the desilter targets even finer solids. What distinguishes this system is that both the desander and desilter are outfitted with underflow shakers. These underflow shakers conduct a secondary treatment on the solids discharged from the upper equipment, ensuring that only the cleanest possible mud remains for further processing. Once the purification process is complete, the mud preparation devices spring into action. Essential mud materials are added to the purified mud, and through thorough agitation, mud with optimal and compliant properties is readied for recycling. This recycling mechanism not only results in significant savings in construction costs by reducing the need for fresh mud procurement but also makes a substantial contribution to environmental protection by minimizing waste.
Solids removal equipment including five stage purification equipment: shale shaker, vacuum degasser, desander, desilter decanter centrifuge. mud degasser and mud desilter can be combined with shaker as mud cleaner.
Auxiliary equipment mainly mean centrifugal pumps and other accessories parts like electrial pannal and so on. According function, centrifugal pump can be used as desander pump, desilter pump, mixing pump,trip pump, and metering pump.
500 HDD Mud Circulation System is applied to construction projects with higher mud capacities. Its purification process is divided into three stages: shale shaker for the first stage, desander and desilter respectively for the second and third stages. Both desander and desilter are equipped with underflow shakers that can carry out a further treatment to solids discharged by the upper equipment. By mud preparation devices, add necessary mud materials into purified mud and stir them evenly to prepare mud with qualified properties for recycling, which can greatly reduce construction costs and effectively protect the environment.
