Countercurrent pass-through ultrasonic processing equipment

Abstract

The invention relates to counterflow passing type ultrasonic processing equipment and relates to a separation extraction and accelerated reaction device. The equipment provided by the invention comprises a charging stock tank, a charge pump, a flowmeter, an ultrasonic processing unit, a liquid storage tank and a circulating pump which are connected and installed through pipelines in the above order, wherein the ultrasonic processing unit contains a buffer, a plurality of ultrasonic processors positioned on the top of the buffer and a collecting pipe for collecting discharged liquids together from each ultrasonic processor. Each of the ultrasonic processors contains an energy-gathered ultrasonic energy transducer, a tube for placing the energy-gathered ultrasonic energy transducer, a tube cover, a process chamber positioned at the lower end of the tube, an overflow mouth which is positioned at the side surface of the tube and is higher than the bottom of the energy-gathered ultrasonic energy transducer, etc. The equipment provided by the invention can be used for extraction and reaction process strengthening treatment such as extraction of effective components in biological resources, enzymatic hydrolysis of biomacromolecules like protein, degradation of harmful substances in sewage and the like.

Description

technical field [0001] The invention relates to a separation, extraction and accelerated reaction device, which belongs to the fields of food, medicine and chemical industry, in particular to a countercurrent passing ultrasonic treatment device. technical background [0002] With the development of science and technology and the acceleration of industrialization, ultrasound, as a physical method, is increasingly used in the extraction of active ingredients of various biological resources, degradation and structural modification of biological macromolecules, and various Strengthening of chemical reactions and biological reactions in the fields of energy and chemical industry, etc. Ultrasound mainly produces local and instantaneous high temperature and high pressure through cavitation, exerts a strong force on the liquid to be treated, accelerates the rupture of cells, and is beneficial to the dissolution of intracellular components; strengthens the breaking of chemical bonds,...

Problems solved by technology

[0004] In order to overcome the deficiencies of the above-mentioned ultrasonic treatment method, the patent ZL200510021970.0 has been improved and proposed to use the tubular circulation method to improve the utilization efficiency of ultrasonic waves, but the present invention The disadvantage is that the treatment liquid enters from the upper part of the tubular reactor and flows out from the lower part. On the one hand, this structure is not suitable for the treatment system with a lot of solids, because it is easy to cause the outlet to be blocked. On the other hand, the liquid flows in the same direction as the ultrasonic wave. , the stirring effect is not good

This invention solves the problem of downstream flow and easy blockage of the patent ZL200510021970.0, but the circulation pipe for ultrasonic treatment and the extraction tank are integrated, and the existing problems are (1) the structure is relatively complicated, which requires high ultrasonic intensity treatment It is difficult to achieve industrialization; (2) The liquid is directly discharged into the extraction tank. When the extraction time is short, it cannot be guaranteed that all liquids have the opportunity to pass through the ultrasonic treatment area
