II.Product Introduction：

Drilling fluid desilters produced by HONDIN are tertiary solids control devices used in drilling fluid solids control systems. The main working principle of the cyclone is centrifugal sedimentation. When the two-phase (or three-phase) mixed liquid to be separated enters the cyclone at a certain pressure from the feed port of the cyclone, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the different density of particles, the centrifugal force, centripetal buoyancy, fluid drag force and other sizes are different. Under the effect of centrifugal sedimentation, most of the coarse particles (or heavy phase) are discharged through the bottom flow of the cyclone, while most of the fine particles (or light phase) are discharged by the overflow pipe, so as to achieve the purpose of separation and classification. For efficient, high-volume processing of drilling fluids, multiple sets of cyclones can be installed to form a single, in-line desilter. The vertical desilter of Hongding Energy connects 4 'hydrocyclones together through a common inlet and outlet pipeline, and the number of desilter hydrocyclones is 4-20. The mud remover separates particles in the 10-74 micron range from the mud. When the mud contains large particles (40 microns and larger), the mud should first be treated by a desander or similar equipment, and the larger particles should be separated and treated.

The body of the cyclone is the main component of the 4 'cyclone, with the tip of the cone spiraling to the bottom of the vertebral body. The drip nozzle position is installed in the cone hole inside the compression cap. Press cap screw to cone tip. Turning the clamping cap clockwise compresses the drip nozzle, thereby reducing the opening of the drip nozzle. Turn the clamping cap counterclockwise to increase the opening, reduce the pressure on the drip nozzle, and the drip nozzle can be restored to the original size. The injection mode can be adjusted by the opening size of the drip nozzle during operation.

III.Working principle:

A cyclone requires a steady feed pressure (head) and a steady feed speed (GPM). The feed pressure may be determined by the gravity feed system or the centrifugal pump installed in the drilling fluid recovery system. At a lift of 75', each 4 'cyclone has a rated operating flow of 80GPM. When the head (feed pressure), feed speed (GPM) and drip nozzle opening are matched, the cyclone can achieve the best use effect. An imbalance in any of these three variables will have a bad effect on the work of the cyclone. The pressure gauge mounted on the mud desilter is used to monitor the feed pressure. The mud enters the lower end line of the cyclone and then uniformly enters the inlet of the cyclone. The liquid discharged from the cyclone flows directly into the upper line of the desilter, and the separated solid flows directly into the funnel installed at the lower end of the cyclone. The material removed from the funnel usually falls to the bottom flow screen of the drilling fluid desilter.
