Circular micro-bubble generating device

Abstract

The invention discloses a circular micro-bubble generating device, which comprises a micro-bubble generating cavity, a Venturi pipe micro-bubble generator, a pressure cavity and a circulating pipeline, wherein the micro-bubble generating cavity, the pressure cavity and the circulating pipeline are sequentially communicated end to end to form a circular passage; the micro-bubble generating cavity is communicated with a water tank via a water pump; the pressure cavity is communicated with a main irrigation pipe; the Venturi pipe micro-bubble generator is arranged in the micro-bubble generating cavity and communicated with an air filling pump via an air pipe; a front valve is arranged on the circulating pipeline; a rear valve is arranged on the main irrigation pipe; a front pressure gauge and a rear pressure gauge are respectively arranged in the micro-bubble generating cavity and the pressure cavity. The circular micro-bubble generating device adopts a simple structure, has a remarkable micro-bubble oxygen addition effect, can adopt a photovoltaic-wind power generation equipment to supply power, protects the environment, saves energy, not only can be used as the oxygen addition and irrigation technique, but also can be applied to efficient oxygen addition of aquaculture, effectively overcomes the defects that a breed oxygen supply system is low in efficiency and high in energy consumption, and can be used as an oxygen addition station of polluted water body to accelerate the degradation of harmful substances.

Description

technical field [0001] The invention belongs to the technical field of new high-efficiency water-saving irrigation machinery, and specifically relates to a circulating microbubble generating device applying hydraulic principles and clean energy. Background technique [0002] The new technology of aerobic irrigation is a low-fertilization, low-pollution, high-quality, high-yield, environmentally friendly and energy-saving new irrigation technology to solve the problem of anoxic stress caused by the contradiction between water and oxygen in the rhizosphere of crops under conventional irrigation. Its potential for increasing production Larger, according to the experimental results of the scientific research group, it is generally known that the production can be increased by 10%-20%, but because the saturated solubility of oxygen in water is very small, to make the oxygen in the water supersaturated, then it is necessary to make the oxygen in a large amount of very small Bubble...
