Desander Unit

GN Desander Unit is a mud recovery and clarify system with compact structure, easy to move and cost-effective. Additional mud storage tank and slurry mixing system can be provided to get the same function with GN Self-Contained Mud Recycling System.

System Description:

Compared with GN Mud Recycling System, GN Desander Unit are designed in more compact structure. It’s easy to move and relocate. GN Desander Unit is largely used in mud cleaning and recycling without mud storage and mixing function, an extra storage tank and a mixing unit can be provided by GN if needed.

Technical Parameters:

GN Desander Unit Working Principle

The slurry pump sucks the mud from the mud pit, than enter into bottom layer screen of shale shaker (3) through buffer box(2), the coarse particles will be separated out and the mud flow to mud storage tank (4) through the bottom layer screen of shale shaker(3). The centrifugal pump (5) takes mud from the recycling tank(4), and feed to desander cone (6) with pressure for centrifugal separation, the solids/sand was discharged to upper shaker(3) from the outlet nipple of the desander cone. After dewatering process of the upper shaker(3), the fine solids was separated out. The mud passed the upper shaker screen returns back to recycling tank(4),the clean mud entered into intermediary tank(7) through desander cone overflow pipe. The mud in the intermediary tank (7) will go out through outlet pipe (9) or go back to recycling tank (4) depends on the fluid level in the recycling tank. In the mud circulation process, there is a fluid level float switch (8) between intermediary tank (7) and recycling tank (4), it can balance the fluids level in the recycling tank(4). When mud level is low in the recycling tank (4) the overflow from the desander will enter recycling tank (4) through the intermediary tank (7). When the mud level is too high in the recycling tank (4), the mud will overflow to the intermediary tank (7) and go out from the outlet pipe (9). If operators want to get high quality clean fluids, the feeding capacity to the system can be reduced, and the repeat cleaning process to get the result.
