A hydroacoustic cavitation loop reactor

Abstract

The invention relates to a hydraulic acoustic cavitation circulation flow reactor which comprises an outer shell and a guide shell arranged in the inner cavity of the outer shell, wherein the upper part of the outer shell is provided with a water outlet; a cavitation sprayer communicated with a water inlet pipeline is arranged between the two walls of the lower part or bottom end of the guide shell; and the cavitation sprayer is composed of a first fixed plate, a first nozzle, a second nozzle, a vibrating bar, a second fixed plate and a connecting rod. The synergic effect is generated under the actions of ultrasonic vibration and slit jet so as to generate abundant free radicals, so that the hydraulic cavitation energy consumption of equipment is lowered, the ultrasonic cavitation intensity is greatly enhanced, the sewage treatment capacity is enhanced, the capacity of hydraulic cavitation for degrading organic pollutants is effectively enhanced, the gas-liquid mixing can be enhanced, and the mass transfer and heat transfer effects between gas and liquid are enhanced. The hydraulic acoustic cavitation circulation flow reactor is convenient to operate and easy for management, has the advantages of low cost, simple technical structure and the like, and is suitable for industrialized popularization and application.

Description

technical field [0001] The invention belongs to the technical field of research on cavitation generating devices for liquid fluids, and in particular relates to a hydroacoustic cavitation circulation reactor for treating organic pollutant waste water through enhanced degradation of hydroacoustic cavitation. Background technique [0002] With the growth of population, the continuous development of social economy, the discharge of sewage is increasing day by day, and the problem of water pollution has become an increasingly serious threat to human survival and social development. Preventing the deterioration of water bodies and protecting water resources have become the common pursuit of mankind. The goal. Traditional treatment methods have played and are playing an important role in the prevention and control of water pollution. However, due to the continuous increase in the amount of wastewater, the increasingly complex composition, and the increasingly stringent treatment ...

Problems solved by technology

[0005] However, although ultrasonic cavitation has high cavitation intensity, only 5% to 10% of the total energy consumption is used for cavitation, and the remaining 90% to 95% of energy is in the form of heat to heat up the system, which makes ultrasonic cavitation The application is greatly limited, it is difficult to achieve industrialization

With the entry of hydraulic cavitation into people's business, we found that hydraulic cavitation has great potential in sewage treatment. Hydronic cavitation technology has more advantages, but hydraulic cavitation has the disadvantage of low cavitation intensity. Therefore, it is particularly important to design a hydroacoustic cavitation circulation device with high ultrasonic cavitation intensity, low energy consumption and high efficiency.
