Gas-liquid or liquid-liquid mixed ultramicro bubble generation device

Abstract

The invention relates to the field of bubble generation, and concretely relates to a gas-liquid or liquid-liquid mixed ultramicro bubble generation device. The device comprises: a cavity comprising an inner flow cavity for accelerating, mixing and cutting liquid I and gas or liquid II and forming a gas-liquid mixture; a flow guide opening used for inputting the liquid I into the cavity; a gas-liquid inlet used for inputting the gas or the liquid II into the cavity; a spiral track arranged in the cavity, namely the inner flow cavity, and used for accelerating the liquid I and the gas or the liquid II in a rotating manner; and a nozzle positioned in the center of the cavity and used for spraying the gas and liquid. Gas-liquid or liquid-liquid mixing can be realized, namely, two fluids with different densities are mixed, the contact time and the contact area of gas-liquid mixing can be increased through the spiral track, gas and liquid can be subjected to repeated rotating and full contact, the gas-liquid mixing efficiency is improved, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of bubble generation, in particular to a gas-liquid or liquid-liquid mixed ultrafine bubble generating device. Background technique [0002] In recent years, there have been several major social problems such as serious pollution of the water environment and serious shortage of water resources in various regions of our country. The country and the government have also attached great importance to water issues. The thirst for water is at an all-time high. [0003] Ultrafine bubbles or vacuoles are widely used in actual production and life. Ultrafine bubbles can be used in various fields of life, such as fruit and vegetable cleaning, aquaculture, crop production increase, sewage purification, health drinks, medical treatment, etc. Ultrafine vacuoles can be used Allow solutions of different densities to fully mix, used in industrial, medical, and new energy fields. However, the concentration of ultrafine bubb...

AI Technical Summary

Problems solved by technology

However, the concentration of ultrafine bubbles produced by the existing ultrafine bubble generating device is too low, the number of ultrafine bubbles is too small, and it is not easy to preserve for a long time. Moreover, the existing ultrafine bubble generating device has high power, high energy consumption, and huge equipment It is bulky, has a small scope of application, is difficult to be widely used in the field of daily life, and cannot meet the actual needs of multi-purpose

[0004] In response to the above shortcomings, the applicant proposed a technical solution (hereinafter referred to as "the solution") of a convoluted ultra-fine bubble generating device (application publication number CN109316990A) on November 23, 2018. Micro-bubbles solve the problems of large volume, high power, high energy consumption and low efficiency of traditional bubble generators, and greatly expand the application range of ultra-micro bubble generators

However, there are still shortcomings in this solution: the inner flow chamber is placed outside, which cannot further compress the volume of the entire device, and its diameter is larger than the negative pressure chamber, resulting in a large energy loss from the negative pressure chamber into the inner flow chamber; liquid (or gas) in the During the process from the negative pressure chamber to the inner flow chamber and being stirred into a mixed liquid, the overall number of turns of the spiral acceleration is still not high, so the gas-liquid mixing efficiency and cutting and stirring efficiency will need to be improved
