Automatic energy adaptive type water-mist H2O2 synthesis method based on absorbance monitoring and rod-like array

Abstract

The invention discloses an automatic energy adaptive type water-mist H2O2 synthesis method based on absorbance monitoring and a rod-like array. The device comprises a gas-liquid inlet control unit, anO2 circulation unit, a H2O2 generation unit, a data acquisition and control unit, an O2-O3 separation unit, a high-voltage excitation unit, a gas-liquid separation unit, an absorbance detection unit,an H2O2 separation unit, an O3 storage, an H2O2 storage and a solution storage; a non-equilibrium plasma processing system is established in water mist spray by regulating electric parameters and regulating the optimal discharge environment, a spray nozzle is adopted to spray water mist jet flow, the diffusion zone is large, processing flow is high, and due to simple manufacture of a rod-like array reactor, self-capacitance can be reduced, energy loss can be reduced, and a large-area discharge zone is applicable to high-flow production. Raw materials for preparing H2O2 by the device comprisea NaCl solution and O2 and are easy to obtain, and yield is high.

Description

technical field [0001] The invention relates to the field of environmental application of discharge plasma, in particular to an absorbance monitoring rod-shaped array automatic energy adaptation water mist synthesis hydrogen peroxide device. 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, ...
