GN Desanding Plant Working Principle

The slurry with a large amount of sediment from the No. 1 slurry pit is pumped into the No. 2 mud feeding box by an external pump. It is then led from the No. 2 tank to the lower screen of the No. 3 shale shaker for screening. Large sediment particles are discharged out of the system, and the slurry with small solid particles passes through the lower screen and falls into the No. 4 slurry tank. The slurry in the No. 4 tank is powered by the No. 5 slurry pump and sent from the inlet of the No. 6 hydrocyclone into it. After the vortex centrifugal separation in the No. 6 hydrocyclone, the sediment is discharged from its bottom outlet, falls onto the upper screen of the No. 3 shaker for drying and discharging. The clean slurry after separation overflows from the top outlet of the No. 6 hydrocyclone into the No. 4 tank. When the liquid level in the No. 4 tank is below the designed closing height of the No. 8 float ball control device, the device is open and the clean slurry enters the No. 4 tank, forming an internal self-circulation. When the liquid level reaches the designed height, the device closes and the clean slurry overflows from the upper outlet of the No. 4 tank into the onsite slurry storage tank.
When sedimentation occurs at the bottom of the No. 4 slurry tank, the valve can be switched to open the No. 7 spray pipe. The slurry is sprayed through the flushing nozzles to circulate and stir, realizing the cleaning of the sediment in the tank.
