Bubbling reaction cleaning device and method

Abstract

The bubbling reaction cleaning set and method is based on bubble interface diffusion layer compressing technology. The pneumatically generated bubble wall is utilized as the reaction interface of the hetero gas-liquid-solid system. During the climbing and dragging course of the bubble along the surface of the material to be cleaned, the liquid-solid interface layer is compressed to optimize the interface mass transfer efficiency and to eliminate the organic pollutant in the material surface effectively.

Description

technical field [0001] The invention relates to a cleaning device, which is applied to remove organic matter on a specific material, in particular to a bubble reaction cleaning device and method using ozone. Background technique [0002] Heterogeneous reaction systems exist in various industries, such as catalytic reaction systems and long-film processes for high-end electronic components. How to improve the heterogeneous mass transfer efficiency of heterogeneous reaction systems in multiphase) is the focus of research and development of related process technologies. In the heterogeneous reaction system where gas-liquid-solid coexistence, since the reaction must be carried out through the interface layer of gas-liquid and liquid-solid phase, the thickness of the interface diffusion layer and The update frequency of the reaction interface has become a key bottleneck affecting the reaction rate. [0003] Generally, traditional technologies use operations such as mechanical st...

Problems solved by technology

[0012] In the current known technology, the most commonly used method is still to use sulfuric acid to clean, but this method has the following disadvantages: high temperature process (120 ° C), large water consumption, large waste acid discharge, and inability to treat materials with metal layers, which is very difficult. Consumes resources and is not environmentally friendly
