Vacuum excavation dewatering system used in North America site
2021-08-31 15:02:40

In July 2021, the vacuum excavation dewatering system produced by GN Solids Control was sold to North America and started to be used.

 

The specific configuration of the vacuum excavation dewatering system is as follows

 

1. GN Solids Control shale shaker (coarse screen))

The mud contains a large number of solid particles, and the particle size distribution of the solid particles is uneven. Some of the particles are larger in diameter. If they enter the fine sieve directly, they will cause greater abrasion. Therefore, the large particles are separated through the vibrating coarse sieve.

 

2. GN Solids Control shale shaker (fine screen)

The mud processed by the GN coarse screen is transported to the GN fine screen by a centrifugal sand pump. The GNZS706 double-layer sieve is used this time, and the solid particles larger than 100un in the mud after the treatment of the GN fine sieve will all be separated. Ensure that the subsequent desilter has a better effect.

 

3. Desilter

The sludge treated by the vibrating fine screen is transported to the desilter by a centrifugal sand pump. The desilter is mainly composed of 12 4-inch desilter cyclones, and solid particles above 25um can be separated by the desilter.

4. Centrifuge

The mud processed by the desilter is transported by the screw pump to the GN Solids Control centrifuge. The centrifuge model is GNLW553C-VFD. The large 22-inch drum diameter has a higher separation factor to ensure the recovery of the mud and the specific gravity of the mud.

 

5. Chemical dosing device

Before the centrifuge is processed, the chemical dosing device needs to be used for dosing and mixing, and the mixed slurry is better treated by the centrifuge.

 

6. GN Solids Control mud tank

The mud processed by the vibrating screen, desilter, and centrifuge needs to be stored in a mud tank. The GN mud tank has a certain inclination angle to facilitate sand removal.
