Title:
DEVICE, SYSTEM, AND METHOD FOR DELIVERING AND SEPARATING TURBID LIQUID
Document Type and Number:
WIPO Patent Application WO/2017/216864
Kind Code:
A1
Abstract:
Provided is a technology for separating suspended matter in a turbid liquid by means of ultrasonic waves, which enables achieving of high separation performance and efficient separation of suspended matter in a turbid liquid. A turbid liquid delivering/separating device 10 has a liquid delivering/separating part 9 including a liquid delivering/separating unit 3. The liquid delivering/separating unit 3 has: a hollow structural body serving as a flow channel through which a turbid liquid 6 is delivered; lateral surface parts which extend in the x-direction of the hollow structural body; a supply port which is provided in one of the lateral surfaces; a discharge port which is provided in the other lateral surface; two flat surface parts that extend in the y-direction of the hollow structural body so as to face each other; and an ultrasonic vibration part which is provided on at least one of the two flat surface parts so as to generate ultrasonic waves in the flow channel. While the turbid liquid 6 is being delivered through the flow channel of the liquid delivering/separating part 9, suspended matter in the turbid liquid 6 is captured by ultrasonic waves and is separated in the z-direction, which is the vertical direction. A first angle formed between the x-direction or the y-direction and a liquid delivery direction corresponding to a straight line connecting between the center point of the supply port and the center point of the discharge port, is an acute angle.
