Motor regulation and control underwater dense bubble dielectric barrier discharge reactor

Abstract

The invention discloses a motor regulation and control underwater dense bubble dielectric barrier discharge reactor. The motor comprises a base, a shell installed on the base, a water storage tank, a pump assembly, a valve assembly, a high-voltage pulse power supply, a data collection and control unit, a mechanical agitation device used for generating underwater dense bubble two-phase flow, a spectrum detector and a liquid level sensor. A dielectric barrier discharge electrode array, a punched net board and an aeration device are arranged in the shell. The dielectric barrier discharge electrode array is connected with the high-voltage pulse power supply. The liquid level sensor and the spectrum detector are connected with the input end of the data collection and control unit. The output end of the data collection and control unit is connected with the pump assembly, the valve assembly, the high-voltage pulse power supply and a speed regulation driver. Water treatment channel selection and gas circulation are achieved by the pump assembly and the valve assembly under control of the data collection and control unit. High-flow wastewater can be treated by the reactor, discharge is easy, a discharge area is large, treatment efficiency is high, and cost is low.

Description

technical field [0001] The invention relates to a reactor, in particular to an underwater dense bubble dielectric barrier discharge reactor regulated by a motor, and belongs to the technical field of reactors. Background technique [0002] Ultrasound-assisted underwater dense bubble DBD discharge effectively reduces the difficulty of discharge, can recycle the ozone generated by discharge, and fully utilizes the synergistic catalytic reaction of discharge ultraviolet rays and titanium dioxide to enhance the treatment effect, which has a good application prospect. [0003] Underwater dielectric barrier discharge needs to generate uniform and dense bubbles. The main reasons are as follows: (1) underwater discharge (especially dielectric barrier discharge) is very difficult; s efficiency. [0004] There are two ways to generate uniform and dense underwater bubble groups: [0005] (1) The physical control method to reduce the difficulty of discharge: reduce the dielectric cons...
