Abstract

The invention discloses a design and parameter regulation method for a pulse corona discharge water mist H2O2 synthesizing apparatus which includes: a gas and liquid inlet control unit, a gas and liquid mixing and generation unit, a high voltage excitation unit, a gas and liquid separation unit, an oxygen / ozone separation unit, an oxygen circulating unit, a H2O2 separation unit, an absorbance detection unit, a data collection and control unit, and a pressure sensor which is used for measuring gas and liquid pressures and a flow sensor which is used for measuring gas and liquid flow rates. IN the apparatus, by means of line-line array-type high voltage pulse corona discharge, an optimal discharge environment is adjusted by means of regulation on electrical parameters, so that a non-balanceplasma processing system is established in a water mist spray; water mist jet flow is sprayed by a nozzle, so that diffusion area is large and processing flow rate is high. Because the linear array-type reactor is easy to produce, self-capacitance is reduced and energy consumption and loss is reduced. The method is suitable for large-scale production of the H2O2.

Description

technical field [0001] The invention relates to the technical field of plasma synthesis chemicals, in particular to a device and a method for synthesizing hydrogen peroxide with pulsed corona discharge water mist. 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, discharge plasma APPs have good application prospects in the fields of air purification, water treatment, ozone synthesis, surface treatment, biomedicine, and materia...
