Hydraulic-ultrasonic combined microbubble generating device and system

Abstract

The invention discloses a hydraulic-ultrasonic combined microbubble generating device and system. The hydraulic-ultrasonic combined microbubble generating device comprises a microbubble generating cavity, a shrinkage section and a throat pipe. A water inlet pipeline, the shrinkage section, the throat pipe and a water outlet pipe are sequentially communicated end to end to form a circulative passage, the water inlet pipeline is communicated with a water tank via a connecting water pump, the water outlet pipeline is connected with a water outlet groove, and the water inlet pipeline is provided with a valve. The hydraulic-ultrasonic combined microbubble generating device is simple in structure, convenient to operate and remarkable in microbubble oxygenation effect. The hydraulic-ultrasonic combined microbubble generating device can be applied to effective oxygenation of fishery breeding and solve the problem of low efficiency and high energy consumption of an existing fishery breeding and oxygenating system effectively and can be largely promoted with the novel technology. In addition, sewage can be oxygenated, and degradation of harmful substances can be accelerated; the hydraulic-ultrasonic combined microbubble generating device can also be used for oxygenation and irrigation of crops to increase yield.

Description

technical field [0001] The invention belongs to the technical field of novel hydraulic combination ultrasonic oxygenation machinery, and is specifically a microbubble oxygenation device applying hydraulic principles and ultrasonic generation principles. Background technique [0002] The new technology of the microbubble generating device is to solve a series of problems such as high energy consumption and large volume caused by the low oxygenation efficiency in the conventional oxygenation method. It is an oxygenation machine with small size, high oxygenation efficiency and simple operation. new technology. The device can be applied to pond oxygenation, sewage treatment, oxygenation irrigation and other fields, and the oxygenation effect is remarkable. Since the saturation solubility of oxygen in water is very small, to make oxygen in water supersaturated, it is necessary to make oxygen exist in the water body in the form of a large number of extremely small bubbles. It ca...

AI Technical Summary

Problems solved by technology

[0003] At present, there is an ultra-microbubble oxygenation device designed based on the principle of increasing the water inlet water depth, water inlet pressure or reducing the bubble diameter to increase the oxygen absorption rate. However, due to the cumbersome structure of the device, the installation is difficult, the price is high, and the market promotion is difficult. , and it is not easy to carry and other shortcomings, it has not been promoted
