AI Technical Summary

Technical Problem

When existing residual liquid discharge devices introduce air through a blower to exchange heat with the liquid via vertical convection, the air blown onto the liquid surface is prone to dissipation, resulting in insufficient contact and affecting the gasification efficiency.

Method used

The air guiding structure and air distribution mechanism driven by a high-pressure fan introduce air into the cryogenic liquid through evenly distributed air distribution holes in the annular pipe and connecting pipe. The shearing force and turbulence generated by the swirl blades cut through the large air bubbles, increasing the gas-liquid contact area.

Benefits of technology

It improves vaporization efficiency, ensures full contact between air and liquid, forms more bubbles, and enhances the vaporization effect.
