An Optimum Design Method for Tubular Separator

Abstract

The invention puts forward an optimal design method for a tube-type separator by aiming at the design of a tube-type separator in the field of sewage processing. According to the Reynolds number of the main separation tube of the separator, a tube diameter and a horizontal flow velocity are calculated; according to the grain diameter of the separation particles, a settling velocity is determined so as to determine the tube length of the separator; and then, a CFD (Computational Fluid Dynamics) technology is adopted to simulate a hydraulic power flow state in the separator, a separation rule ismade clear, and an optimal size and operation parameter can be determined. The tube-type separator is separation equipment which is newly invited and does not have a design standard and an empiricalparameter for tracing. A traditional displacement separation and pipeline design method is not suitable for the separator. The invention puts forward the optimal design method for the tube-type separator, and the optimal design method has the advantages of being convenient in design, accurate, short in period, low in cost and the like.

Description

technical field [0001] The invention relates to an oil cement separator in the field of sewage treatment, in particular to an optimal design method for a tubular separator. Background technique [0002] Most oilfields in China have entered a period of high water content (more than 80% water content), and sewage treatment has become one of the important restrictive factors for surface engineering in various oilfields. The traditional sewage treatment process often uses the large tank settlement method, which mainly has sewage residence time Shortcomings such as length, large floor area, and difficulty in mud discharge. In response to these shortcomings, in recent years, some people have researched and invented tubular separators, such as T-shaped tubes, I-shaped tubes, and grid-shaped tubular separators. The tubular separator has the advantages of short separation residence time, high separation efficiency, and easy sludge discharge. Since the tubular separator is a new typ...

Problems solved by technology

[0006] The purpose of traditional pipeline design is to calculate the head loss of the pipeline according to the empirical formula such as Sheverev, so as to determine the diameter of the pipeline and the selection of the pump, and rarely consider the separation of the liquid in the pipeline

Although the tubular separator has the characteristics of the pipeline, its design concept is completely different from the pipeline design. Its main concern is the separation effect of the liquid in the tube, so the pipeline design method is not suitable for the design of the tubular separator.
