The invention relates to a micro-nano bubble
oxygenation drip irrigation system and a micro-nano bubble
oxygenation drip irrigation method. The
system comprises a water inlet main
pipe, wherein the water inlet main
pipe is connected with two branches in parallel, and a first
branch is sequentially connected with a water pump, a pressure stabilizing tank and a
pipe pump; a
spray nozzle which stretches into the pressure stabilizing tank is arranged at an inlet end of the pressure stabilizing tank, and a pressure stabilizing valve is arranged at the top of the pressure stabilizing tank; a pressure gauge is arranged on an outlet pipeline of the pipe pump; a flow regulating valve and a pressure gauge are sequentially connected onto a second
branch; the two branches converge to form a water outlet main pipe; the position, at an inlet of the water pump, of the first
branch is connected with an outlet of an
air pump through an
electromagnetic valve and an inlet of the
air pump is respectively connected with a
pure oxygen source and an
ozone source; a one-way valve and a gas flowmeter are sequentially arranged between the
pure oxygen source and the
air pump; a one-way valve and a gas flowmeter are sequentially arranged between the
ozone source and the air pump; the pipe pump is electrically connected with a
frequency conversion cabinet, the
frequency conversion cabinet is electrically connected with a power distribution box through an
electromagnetic valve and the power distribution box is electrically connected with a programmable controller; the flow regulating valve, the pressure gauges, the electromagnetic valves, the gas flowmeters, the water pump, the pipe pump and the power distribution box are respectively and electrically connected with the programmable controller.
