Abstract

The invention discloses a device and method for synthesizing hydrogen peroxide from water mist by DC corona discharge. The device includes a gas-liquid inlet control unit, a gas-liquid mixing generation unit, a high-voltage excitation unit, a gas-liquid separation unit, 2 and O 3 Separation unit, O 2 cycle unit, H 2 o 2 A separation unit, a control unit, a pressure sensor for measuring the gas-liquid pressure, and a flow sensor for measuring the gas-liquid flow rate; the present invention adopts a line-array type high-voltage DC corona discharge to establish a non-equilibrium plasma in the water mist spray The treatment system uses nozzles to spray water mist jets, which has a wide diffusion area and a large treatment flow rate; due to the simple fabrication of the line array reactor, it can reduce its own capacitance and reduce energy loss, and its large discharge area can be applied to large flow production , and adopts corona discharge, low current and low power consumption. The raw materials for producing hydrogen peroxide in the present invention are easy to obtain and the yield is high. Therefore, the present invention is suitable for large-scale production of hydrogen peroxide.

Description

Technical field [0001] The present invention relates to the field of plasma synthetic chemicals, and more particularly to devices and methods for synthesizing hydrogen-flowing water mist synthesis of DC. Background technique [0002] In recent years, the environmental application of discharge plasma has become the forefront of scientific research, and it has become an increasingly hot topic. As a high-grade oxidation process (AOPS), discharge plasma has a more significant feature, which has the advantage of high efficiency and fast speed compared to the process of biodegradation absorption. In addition, discharge plasma (APP) can be generated under atmospheric pressure or higher, and there is no need to use expensive vacuum equipment, there are more economic and application value. Therefore, discharge plasma APPs has good application prospects in air purification, water treatment, ozone synthesis, surface treatment, biomedicine, material modification and other fields. The dischar...
