AI Technical Summary

Technical Problem

Existing bubble generating mechanisms struggle to achieve adequate mixing of air and liquid, and the resulting micro- and nano-bubbles are unstable and prone to rupture inside the bubble generator.

Method used

Design a bubble generating mechanism. The liquid flow channel of the inner shell consists of a first flow channel, a throat, and a second flow channel. The inner diameter of the first flow channel gradually decreases, the inner diameter of the throat is the smallest, and the inner diameter of the second flow channel gradually increases. It is equipped with a spiral flow channel and a smooth wall surface. The air inlet channel is circumferentially connected to the throat. Combined with the guide groove and sealing assembly, it ensures that air enters the liquid flow channel evenly.

Benefits of technology

This technology enables efficient mixing of air and liquid to form stable micro- and nano-bubbles, improving bubble stability and uniformity, reducing the amount of chemical reagents used, and lowering processing and wastewater treatment costs.

Abstract

The invention discloses a bubble generating mechanism, a micro-nano bubble host comprising the bubble generating mechanism and application of the bubble generating mechanism in the processing technology of photovoltaic cells. The bubble generating mechanism comprises an outer shell and an inner shell which are sleeved with each other, a liquid flow channel allowing liquid to flow through is formed in the middle of the inner shell and comprises a first flow channel, a throat part and a second flow channel, and the end, close to the second end, of the first flow channel is connected with the throat part; the inner diameter of the throat portion does not exceed the inner diameter of the end, close to the second end, of the first flow channel, the inner diameter of the second flow channel is gradually increased in the direction close to the second end, the inner surface of the second flow channel is a smooth wall face, the air inlet flow channel communicates with the liquid flow channel in the circumferential direction, and the air inlet flow channel communicates with the throat portion in the circumferential direction. And the inner surface of at least partial area of the first flow channel is a spiral flow channel. The bubble generating mechanism can ensure that the generated micro-nano bubbles are smaller in particle size and more stable.
