Ultrasonic detection-based separation system for media with different specific gravity

Abstract

The invention relates to an ultrasonic detection-based separation system for media with different specific gravity, and belongs to the technical field of liquid separation. The system is characterizedby comprising a liquid storage tank (5), wherein a medium input pipeline (1) for conveying a medium into the liquid storage tank (5) is arranged at the side part of the tank top of the liquid storagetank (5), a heavy medium output unit is arranged at the tank bottom of the liquid storage tank (5), three sets of ultrasonic detection units are arranged on the side part of the liquid storage tank (5) in order from top to bottom, each ultrasonic detection unit comprises an ultrasonic transmitting end and an ultrasonic receiving end, and each ultrasonic transmitting end and the corresponding ultrasonic receiving end are arranged symmetrically along the radial direction of the liquid storage tank (5). In the ultrasonic detection-based separation system for media with different specific gravity, multiple sets of the ultrasonic detection units are arranged, the detection of a light medium and a heavy medium is realized by monitoring the ultrasonic sound velocity, and thereby the separation of media with different specific gravity is realized.

Description

technical field [0001] The invention relates to a separation system of media with different specific gravity based on ultrasonic detection, which belongs to the technical field of liquid separation. Background technique [0002] The current liquid interface detection and control technology mainly adopts the technology of conductivity detection method or bellows interface controller. The conductometric detection method is to judge the different conductivities of different media, but this method will be difficult to obtain correct results when the conductivities of the two liquids are very close; the bellows controller uses bellows for differential pressure detection Parts are distinguished according to the pressure of the bellows in different liquids, but this method can only detect the pressure of the surrounding medium in the medium where the end of the outlet pipe extends, and cannot detect the pressure on the horizontal plane where the end of the outlet pipe is located. ...

The conductometric detection method is to judge the different conductivities of different media, but this method will be difficult to obtain correct results when the conductivities of the two liquids are very close; the bellows controller uses bellows for differential pressure detection Parts are distinguished according to the pressure of the bellows in different liquids, but this method can only detect the pressure of the surrounding medium in the medium where the end of the outlet pipe extends, and cannot detect the pressure on the horizontal plane where the end of the outlet pipe is located. Therefore, the boundaries of the liquid levels of different media cannot be determined
