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.
