Abstract

The invention relates to a cross-flow whorl solid-liquid separator, which is characterized in a cylinder cyclone room. Wherein, said cyclone room is separated by cylinder catch net into coaxial inner chamber and outer chamber; the bottom of inner chamber is supported by a soil collecting chamber; the water inlet tube is tangentially arranged along cylinder cyclone room; the water inlet is above the inner chamber and through to it; the inlet water-flow is tangentially filled into inner chamber; a tangential overflow water outlet tube is arranged which is through to the outer chamber; the bottom of soil collecting room is through to the soil discharge tube. The invention has high efficiency, lower cost, lower energy consumption, simple operation, and the application for water and waste water pretreatment, to complete filtration and sand deposition in one step.

Description

Technical field: [0001] The invention relates to a solid-liquid separation device, more specifically, a device used in water or waste water pretreatment process to realize the purpose of intercepting suspended matter in water and removing sand. Background technique: [0002] my country is a water-scarce country, and the per capita water resources are less than 1 / 4 of the world's average level. For sewage treatment, the current national sewage treatment rate is less than 40%, and the sewage reuse rate is less than 5%. Sewage discharge will inevitably Cause water environment pollution, make drinking water source quality worse. However, water and sewage treatment not only requires a huge investment in the construction of water treatment plants, but also high daily operating costs. Therefore, seeking and developing high-efficiency, low-consumption, and low-investment water treatment processes and devices is an inevitable way to promote the coordinated development of economic dev...
