Description

Combined sand removal and separation device

Technical Field

The utility model belongs to the technical field of sand removal, and particularly provides a combined sand removal and separation device.

Background

A desanding separator is a device for separating solid particles (e.g. sand, mud, etc.) from a liquid. The method separates solid particles from liquid by high-speed rotation (such as a cyclone filter sand remover) or gravity slow sedimentation (such as a advection sand remover), thereby achieving the purpose of sand removal. The cyclone filtering desander has relatively short time consumption and high energy consumption during desanding; the horizontal flow sand remover has relatively long sand removing time and low energy consumption.

The inventors have attempted to combine both a advection desander and a swirl desander to avoid the problems of either high energy consumption or long time consumption when either a swirl filter desander or a advection desander is employed alone.

However, when the two sand removers are combined, especially, two sand removers are purchased externally, and the structural size of the sand removers is not changed: sufficient distance needs to be reserved between the cyclone filtering sand remover and the main structure of the cyclone sand remover so as to avoid interference between the positions of the two sand removers. Specifically, a longer vertical pipeline is arranged between the outlet at the lower end of the cyclone filtering sand remover and the inlet of the advection sand remover, the inner diameter of the pipeline is relatively smaller, the ratio of the length of the pipeline to the inner diameter is small, and the pipeline is very easy to be blocked.
