It answers in case 19, the 2nd pH detector 25 is provided on the pipeline, if pH is not up to standard, continue in the second neutralization reaction case 19
Acid-base neutralization medicament is added and carries out neutralization reaction, waste water enters water tank 20 and stored after completion of the reaction；If pH value is up to standard
Then it is not necessary that medicament is added, waste water is pumped directly into water tank 20 by the second neutralization reaction case 19.Waste water in water tank 20 is successively
After the processing of ultrafiltration membrane filter, nano-filtration membrane filter and reverse osmosis unit, recycle generated dense in reverse osmosis unit
Water discharges generated fresh water in reverse osmosis unit, can be back to fresh water in the first liquor box 9 repeat to make according to actual needs
With.In order to guarantee laboratory in use the exhaust treatment system can continual processing exhaust gas, entire gas path pipe
It must keep clear, therefore be provided with three the first liquor boxs 9 in parallel altogether, each first liquor box 9 is communicated to the
One neutralization reaction case 18 (is not shown in the figure, is illustrated only shows first liquor box 9 and the first neutralization reaction for the sake of clarity
Case 18 is connected to).During processing, at least first liquor box 9 is kept to be in the state for absorbing exhaust gas, when some is first molten
When liquid case 9 absorbs saturation, second control valve 8 corresponding with first liquor box 9 is closed, then according to above-mentioned processing waste water
Method handles the waste water in the first liquor box 9, and the first liquor box 9 moisturizing and opens corresponding again after being disposed
Two control valves 8 come into operation.
The exhaust gas handled by the first liquor box 9 enters the second liquor box 11 by pipeline, what the second liquor box 11 contained
Kerosene is used to absorb the volatile organic matter voc in exhaust gas, closes and is arranged in the second liquor box after absorption reaches saturation state
Waste water in second liquor box 11 is delivered in evaporator 26 by the third control valve 10 of 11 inlet ends by pipeline and pump, is led to
The pervaporation effect property of will volatilize organic matter voc is recycled in plenum chamber 27 and is stored, and the kerosene in evaporator is then back to the
It is reused in two liquor boxs 11.For the purposes of guaranteeing that the exhaust treatment system can be continual in use in laboratory
Exhaust gas is handled, entire gas path pipe must keep clear, and be provided with three the second liquor boxs 11 in parallel altogether, each second
Liquor box 11 is communicated to evaporator 26 and (is not shown in the figure, is illustrated only shows first liquor box 9 and for the sake of clarity
One neutralization reaction case 18 connection).During processing, at least second liquor box 11 is kept to be in the state for absorbing exhaust gas,
When some second liquor box 11, which absorbs, to be saturated, close corresponding with the second liquor box 11 third control valve 10, then according to
Above-mentioned processing method handles volatile organic matter voc, and kerosene is back to the second liquor box 11 and opens corresponding
Three control valves 10 come into operation.Exhaust gas in plenum chamber is subjected to burning processing or other harmless treatments.
Pass through discharge after the exhaust gas of the second liquor box 11 processing carries out adsorption treatment in entering the second adsorption box 12
Pipeline is expelled to outdoor, is provided with active carbon filler in the second adsorption box 12, the outlet of the second adsorption box 12 on discharge tube
End is disposed with voc detector 28, the first blower 13 and the 4th control valve 14, wherein the first blower 13 is entire exhaust-gas treatment
The gas path pipe of system power source is provided and voc detector 28 then for detecting by the second adsorption box 12 treated gas
In voc content, open the 4th control valve if voc content is up to standard and gas be emitted into outdoor, pass through if not up to standard
