Abstract

The invention discloses a miniature hydrogen peroxide synthesis apparatus through corona discharge and water mist. The synthesis apparatus comprises a liquid-phase conveying unit, a gas-liquid mixed water mist generation unit, a corona discharge unit, and a H2O2 collection unit. The corona discharge unit comprises several module groups, the module group comprises a negative electrode layer and a positive electrode layer, the negative electrode layer and the positive electrode layer are stacked in a crossed mode, and the negative electrode layer and the positive electrode layer are mutually parallel. The negative electrode layer can be uniformly filled with a negative electrode, the positive electrode layer can be uniformly filled with a positive electrode, and the negative electrode numberon the negative electrode layer is one more than the positive electrode number on the positive electrode layer. The negative electrode is subjected to ground connection, and the positive electrode isconnected with high-voltage supply. The invention also discloses a design method of the miniature hydrogen peroxide synthesis apparatus, a line-line array reactor is employed, and the production is simple.

Description

technical field [0001] The invention belongs to the field of hydrogen peroxide production, and in particular relates to a small-sized corona discharge water mist synthesis hydrogen peroxide device and a design method thereof. Background technique [0002] In recent years, the environmental application of discharge plasma has become the frontier of scientific research and has become an increasingly popular topic. As a kind of advanced oxidation process (AOPs), discharge plasma has more remarkable characteristics, and it has the advantages of high efficiency and fast speed compared with the process of biodegradation and absorption. In addition, discharge plasma (APP) can be generated at atmospheric pressure or higher pressure without using expensive vacuum equipment, which has more economic and application value. Therefore, APPs have good application prospects in the fields of air purification, water treatment, ozone synthesis, surface treatment, biomedicine, and material mod...
