Specific implementation mode
Device or equipment described in following embodiments are existing device or equipment unless otherwise specified.
A kind of micro-hole aerator Performance Test System of embodiment
The present embodiment is a kind of micro-hole aerator Performance Test System, as shown in Figure 1, it includes being sequentially connected by pipeline
Air compressor machine 1, voltage regulating meter 2, PLC control devices 3, flowmeter 4 and micro-hole aerator 7, micro-hole aerator 7 is located in aeration tank 6.
Wherein：1 model screw compressor WLF-15MV, PLC control device of air compressor machine, 3 model Siemens 6ES7288-
Device with control piper break-make made of 1SR20-0AA0 and MAC solenoid valves 52A-11-F0B-GM-GDFA-1BA concatenations,
4 model flowmeter LZB-25 of flowmeter.Arrow indicates the flow direction of gas in figure.
Under test mode, water is full of in aeration tank 6, micro-hole aerator 7 is located at the water surface hereinafter, being additionally provided in aeration tank 6
The test probe of dissolved oxygen sensing instrument 5 for detecting oxygen content in water, dissolved oxygen sensing instrument 5 is located at the water surface or less.
Since water quality distinguishes larger, the aperture very little in the micro-hole aerator 7 of the present embodiment end, a period of time is used
Afterwards, when water quality is poor especially in aeration tank, it is easy the aperture in blocking microporous aerator 7, aperture blocks in order to prevent, aeration
Agitating device is additionally provided in pond 6, when water quality is poor, which after a period of use, opens agitating device, pass through the strong of water
Turbulent flow makes the deposit being deposited in 7 aperture of micro-hole aerator with flow outflow aperture.It is stirred in addition, being equipped in aeration tank 6
When mixing device, when can also measure that flow is in strong turbulent condition in aeration tank 6, the oxygen mass transfer process in aeration tank 6.
Agitating device is the device for stirring water body, and existing apparatus may be used.
Operation principle：PLC control devices 3 are set as periodically making pipeline on/off, open air compressor machine 1, can pass through tune
Flow, the flow velocity of pressure table 2 and the adjusting hollow gas of pipeline of flowmeter 4, the periodical control piper on/off of PLC control devices 3, to
Flow through the interruption of the air after PLC control devices 3.
The compressed air of discontinuity eventually enters into micro-hole aerator 7 by pipeline, due to being periodically passed through air, micropore
Microporous membrane interruption is heaved/is shunk in the aeration plate of aerator 7, to change the characteristics of motion of microporous membrane, discontinuous gas
Body makes diaphragm up-down vibration, bubble be squeezed, stretch by diaphragm, and bubble size is sheared to obtain smaller, to substantially increase
The bubble of the contact area in gas-liquid two-phase face, the micro-hole aerator 7 that makes to emerge is in one one bubble cluster, is pushed in aeration tank 6
The convective motion of water body increases the turbulent flow of water body, makes adequately to be mixed between solution-air, two be in contact it is more violent into
Row exchanges, and accelerates the update of liquid film in gas-liquid interface, is more conducive to the transmission of oxygen；In addition, since air is with intermittence exposure
Gas mode exports, and increases outlet pressure and speed, improves convection current ability and service area in aeration tank 6, due to generating
Bubble volume it is smaller, bubble is longer from the time being generated to needed for the water surface, i.e., minute bubbles are compared to for larger bubble, it is in water
The residence time of body is longer, extends the mass transfer time between gas-liquid two-phase, to improve the transfer efficiency of oxygen, is aerated increasing
Energy consumption is reduced while efficiency, reduces operating cost.
Above-described embodiment is only the preferred embodiment of the utility model, be not to made by the utility model its
The restriction of its form, any person skilled in the art are changed or are changed as enlightenment possibly also with above-mentioned technology contents
Type is the equivalent embodiment of equivalent variations.In every case it is the technical spirit without departing from the utility model claims, to implementing above
Simple modification, equivalent variations and remodeling made by example, still fall within the range of the utility model claims protection.
