Abstract
The application discloses a water-sand separator, a separation system and a method for evaluating the efficiency of the water-sand separator. The method comprises the following steps: obtaining the path length required for fluid to flow from the inlet to the outlet of the separator, the particle settling velocity, the height difference between the water surface of the inlet pipeline and the downstream pipeline inversion, and the inlet water flow velocity; calculating the first time required for water to flow from the inlet to the outlet of the separator according to the path length and the inlet water flow velocity; calculating the second time required for particles to settle from the water surface of the inlet to the downstream pipeline inversion according to the height difference and the particle settling velocity; and calculating the non-dimensional value of the water-sand separator according to the first time and the second time, wherein the non-dimensional value is the ratio of the first time to the second time. Based on the non-dimensional value, the sediment removal efficiency of the water-sand separator can be determined, and the calculation process is simple and the operation steps are few.
