Ultrasonic solution separating method and ultrasonic separating apparatus used in this method

Abstract

A method for the ultrasonic separation of a solution, wherein the solution is subjected to the ultrasonic vibration in an ultrasonic atomization chamber (4) and atomized into a mist in a conveying gas, the conveying gas containing the atomized mist is transported to a recovering section (5), and a mist component having been atomized to a mist is separated from the conveying gas and recovered in the recovering section (5), which comprises, in the recovering section (5), an adsorption step of contacting the conveying gas containing the mist component with an adsorbing agent (15) to allow the adsorbing agent (15) to adsorb the mist component and a separation step of separating the mist component having been adsorbed on the adsorbing agent (15) in the adsorption step from the adsorbing agent (15) and then recovering it, and separates the mist component from the conveying gas by the absorbing and separation steps and by setting the pressure in the separation step at a value lower than that in the adsorbing step.

Description

technical field [0001] The present invention relates to a method and an apparatus for separating a high-concentration solution with a high concentration of a target substance from a mixture containing two or more substances, or a method and an apparatus for separating a target substance contained in a solution, and in particular relates to an ethanol solution which is most suitable for extracting alcohol or wine raw materials. A method and device for further separating high-concentration ethanol, or separating a solution with a high concentration of target substances from petroleum. Background technique [0002] The present inventors have developed a device for separating high-concentration ethanol from ethanol. (refer to patent document 1) [0003] Patent Document 1: Japanese Patent Laid-Open No. 2001-314724 [0004] The separation device fills the ethanol solution into the ultrasonic atomization chamber with a closed structure, and uses the ultrasonic vibrator to cause t...

Problems solved by technology

At this time, there is a disadvantage that the lower the temperature of the transport gas, the greater the energy required for heating.

[0010] Therefore, the conventional ultrasonic separator has the disadvantage that it is difficult to efficiently and effectively recover the smoke with high ethanol concentration while generating it in the ultrasonic atomization chamber.
