Description
Technical field
The utility model relates to micro-nano bubble oxygenation equipment technical field, specially a kind of micro-nano of accurate feedback control
Rice bubble oxygenation irrigation system.
Background technique
Currently, irrigating dissolved oxygen in water is the important factor for influencing growth rate, dissolved oxygen in growing process
Abundance growth is just fast, and the low not only growth of oxygen dissolved is slow, but also down to the critical value of dissolved oxygen needed for plant hereinafter, there is also anoxic
Rotten, so to improve dissolved oxygen in water as the agent technology of crop irrigation in production, either endless form cultivates mould
How diversified formula is, but be all finally for around feasibility guarantee of the raising as its mode of dissolved oxygen, it is all can allow it is molten in water
The technical measures that oxygen improves all are the well stimulations promoted crop growth and promote development.
So-called micro-nano bubbler techniques are exactly that air or pure oxygen are dissolved in water in a manner of imperceptible bubble, to realize
The over-saturation oxygen condition of water body has achieved the effect that routine is difficult to reach, has played its unconventional effect.Micro-nano bubble is
Ultra micro minute bubbles of the diameter between hundreds of nanometers.Micro-bubble, can be rapidly complete because the effect by surface tension is pressurizeed by self
Fully dissolved Yu Shuizhong and disappear.Micro-nano bubble surface is electrically charged and has electrostatic repulsion, and bubble can reach to a certain degree
It stores for a long time, makes it possible that the stabilisation of nanometer foam exists.With charging effect and stabilized nanometer foam, still protect
The characteristic as bubble is hold, direct influence can produce on the cellular level of biology, in engineering and biologically have bigger
Application is possibly realized.Air Exposure is carried out to irrigation water using micro-nano bubble, oxygen dissolving value can be made to be rapidly reached over-saturation
State forms micro-nano air-bubble for irrigating.Micro-nano bubble phase has large specific surface area, water for common blister
The advantages that middle residence time is long, itself pressurization is dissolved, mass-transfer efficiency is high, gas dissolution rate is high.So that micro-nano air-bubble is not only
It is capable of providing sufficient oxygen, and its distinctive charging property, oxidisability, bactericidal properties etc. make it have special biological physiology and live
Property, promote the growth and development of plant.
In traditional gardening and crop irrigation, the measures such as air pump oxygenation are generally widely used and increase dissolved oxygen in water,
But this method of gas injection bubble is larger, it is difficult to so that oxygen dissolving value in irrigation water is increased sharply, and bubble save in the soil when
Between it is short, utilization efficiency is low, and many scholars propose to utilize pure oxygen micro-nano bubble progress oxygenation also for the persistence of enhancing oxygenation
It irrigates, such as: Chinese patent CN202823183U discloses irrigation water oxygen increasing equipment, for increasing the dissolved oxygen amount of iirigation water source,
Using air or pure oxygen as oxygen source, good effect is obtained.But this method is only used for water-supply source oxygenation, can not be directly accessed filling
It irrigates pipeline directly to use, can also make the aerobic microbiological and some algae fast-growths in irrigation and nutrient solution, will increase in this way
The risk of douche blocking.Chinese patent CN103858730B discloses the micro-nano bubble oxygen-enrichment system of irrigation water, the decorum
Oxyty is measured indirectly by flowmeter, can not really reflect the oxygen dissolving value in irrigation water.And generate the micro- of bubble
Rice magnitude, for resident time in water less than one hour, for large area irrigation, there may be problems: reaching irrigation terminal
When, the loss of possible oxygen bubble is totally.Chinese patent CN102765797B discloses a kind of irrigation water oxygen increasing equipment, this is
The bubble of system can reach micro-nano magnitude, but the water yield of single micro-nano bubble generator only has 1m3/h, and large area fills
It irrigates and needs multiple micro-nano bubble generators, equipment cost is high；How a kind of completely new micro-nano bubble oxygenation irrigation system is designed
System just seems most important.
