[Detailed description of the invention]
Fig. 1 is the structural schematic diagram that aeration oxygenator is used in a kind of teaching of the utility model.
[specific embodiment]
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
With novel further description.
Referring to Fig. 1, the utility model provides a kind of teaching aeration oxygenator, comprising: pedestal 1 is set to bottom vertically
The aeration cylinder 2 of 1 top of seat, the water tank 3 being connected to external water source are compressed with 2 bottom of aeration cylinder by the air that pipeline 11 is connected to
Machine 4；The least significant end of the aeration cylinder 2 is connected to water tank 3 by water pipe 5, and the water pipe 5 is equipped with liquid pump 6 and liquid valve
7, and 2 bottom of the aeration cylinder is equipped with aeration head 8.
Particularly, 2 top of aeration cylinder is connected to at the top of water tank 3 by an overflow pipe 9；The overflow pipe 9 and water 3 connect
It is logical, water extra in aeration cylinder 2 can be discharged into water tank, it is thus possible to prevent from overflowing in aeration cylinder 2 because water level is excessively high, together
When avoid the waste of water.
Particularly, the aeration head 8 is sand hole aeration head；Using sand hole aeration head, so that 8 base drag of aeration head is low,
Hoisting power is strong, to improve oxygen-transfer efficiency.
Particularly, 2 least significant end of aeration cylinder is not less than 3 most significant end of water tank；It is designed in this way, it is ensured that water is made at itself
Water tank 3 is more smoothly flowed under, to guarantee going on smoothly for work.
Particularly, 2 bottom of aeration cylinder is connected to at the top of water tank 3 by a drainpipe 10, which is equipped with
One drain valve (is not painted) in figure, is designed in this way, and the water in aeration cylinder 2 can be discharged into water tank 3 after the end of the experiment.
Particularly, a height of 2-3m of the aeration cylinder 2, the utility model are preferably 2.5m；If the height of aeration cylinder 2 herein
Lower than 2 meters, since water is very little in aeration cylinder 2, causes instructional blocks of time too short, be unfavorable for teaching efficiency；If being higher than 3m, student is not
Facilitate operation, therefore the height of aeration cylinder 2 is 2-3m.
Particularly, the pipeline 11 is equipped with spinner flowmeter 12；The adjustable aeration of the spinner flowmeter 12 uses air
The size of flow, to improve the accuracy of experimental result indirectly.
Using the specific experiment of teaching aeration oxygenator provided by the utility model, steps are as follows:
(1) each valve state of checking experiment device.It is required that: close aeration cylinder, water tank drain valve；Close air valve；It closes
Close liquid valve.
(2) experimental water is configured.Tap water is filled it up with into water tank, raw water volume in water tank is measured, with portable dissolved oxygen instrument
Measure its DO value.
(3) Na is calculated2SO3Dosage.
①Na2SO3Dosage 2Na2SO3+O2=2Na2SO4
The ratio between relative molecular weight are as follows: M (O2)/2M(Na2SO3)=32/2*126=1/8
Therefore Na2SO3Theoretical amount is 8 times of oxygen in water amount.Sulfurous acid can be consumed due to containing partial impurities in water
Sodium, therefore actual amount is 1.5 times of theoretical amount, so the Na2SO3 amount calculation method that experiment adds is as follows:
W1=0.012 ρ V
W1 in formula --- sodium sulfite dosage, unit g；
ρ --- the dissolved oxygen mass concentration measured when experiment, unit mg/L；
V --- raw water volume, unit L.
(4) dosing: Na2SO3 is dissolved with a small amount of water, is uniformly poured into raw water box, while the cobalt salt of dissolution also being poured into
In water, mixing is gently mixed with waddy.
(5) it can be exposed when DO value is reduced to zero or near zero with the DO value in portable dissolved oxygen instrument measurement raw water
Gas oxygenation experiment.
(6) boring aeration is tested
1. opening liquid valve, start liquid pump adds water at 35L to aeration cylinder；
2. closing liquid pump and liquid valve prevent water in aeration cylinder from flowing back；Start air compressor simultaneously；
3. the probe of portable dissolved oxygen instrument is put into aeration cylinder water, if without obvious oxygenation, DO value during water inlet
DO value, the as dissolved oxygen concentration at t0 moment at this time should be recorded close to zero；
4. opening air valve, adjusting gas flow controls its flow within the scope of 0.5~1m3/h；
5. when air is uniformly emerged from aeration cylinder bottom, start in timing and time recording water DO value (at aeration initial stage,
Since the transfer velocity of dissolved oxygen is very fast, can 15s record it is primary；It is primary to can be adjusted to 30s after 2min；It can be adjusted to after 5min
1min is primary) until DO value no longer changes in water.
6. closing air valve, drain valve draining is opened, closes drain valve after water in cylinder empties.
7. changing gas flow re-starts primary experiment, compared with former aeration condition.
