A loop reactor with a guide member

Abstract

The invention relates to a circulation flow reactor with a guiding body component. The circulation flow reactor comprises an outer cylinder and a guide cylinder arranged in the inner cavity of the outer cylinder, wherein a water outlet is formed in the upper part of the outer cylinder; a cavitation spray head communicated with a water inlet pipeline is arranged below the guide cylinder or between two walls of the bottom end of the guide cylinder; a guiding body is arranged in the inner cavity of the guide cylinder; the guiding body is positioned above the cavitation spray head and directly faces the spray end of the cavitation spray head. According to the circulation flow reactor, a synergic effect is generated under the effects of ultrasonic vibration and flapping jet, and a great number of free radicals are generated, so that the hydrodynamic cavitation energy consumption of the equipment is reduced, the ultrasonic cavitation strength is greatly improved, the sewage treatment capacity is strengthened, and the hydrodynamic cavitation capacity for degrading organic pollutants is effectively improved; moreover, gas distribution in liquid is dispersed by using the guiding body, the aggregation of gas in the liquid is prevented, and the gas-liquid contact area is further increased. The circulation flow reactor also has the advantages of convenient operation, easy management, low cost, simple technological structure and the like, and is suitable for industrial popularization and application.

Description

technical field [0001] The invention belongs to the technical field of research on liquid fluid cavitation generating devices, and in particular relates to a loop reactor with a guide member for the enhanced degradation treatment of organic pollutant waste water by 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 constituted 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 of wastewate...

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

As hydraulic cavitation enters people's field of vision, we find that hydraulic cavitation has great potential in sewage treatment, and has the characteristics of simplicity, low energy consumption, and high efficiency. Compared with energy efficiency and scale, hydraulic cavitation technology is better than ultrasonic cavitation. 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.
