Description
Technical field
The present invention relates to air-purifying humidification device.This air-purifying humidification device is for being supplied to the adjustment etc. of the air of the dust free room of semiconductor manufacturing.
More specifically, this air-purifying humidification device possesses gas-liquid contact room.In this gas-liquid contact room, make to be vented to indoor handling object air and clean water carries out gas-liquid contact.
By this gas-liquid contact, the water miscible gas componant in handling object air is removed, and handling object air is cleaned.In addition, along with this purification of air, handling object air is by humidification.
Background technology
All the time, as this air-purifying humidification device, the device of the periodical feeding formula shown in Fig. 1, Fig. 2 of known such as patent document 1.
The device of this periodical feeding formula possesses the storage box of having the clean water (that is, absorbing the clean water of the water miscible gas componant that handling object air comprises) used of discharging from gas-liquid contact room in one's care.
By the clean water of taking out from this storage box circulation is supplied to gas-liquid contact room, thus this supplying clean water and handling object air is made to carry out gas-liquid contact in gas-liquid contact room.
In the device of this periodical feeding formula, the part of clean water is consumed in the humidification of handling object air and processed object air is taken away.
In addition, together brought in storage box from the water miscible gas componant of handling object absorption of air removing with the clean water used.
In contrast, the fresh clean water of necessary amount is replenished to storage box from clean water feedway.
By this supply, the water-soluble gas constituent concentration being supplied to the clean water of gas-liquid contact room is remained on below certain value (that is, remaining on the cleannes necessarily) from storage box circulation.
In addition, on the other hand, the device of the also temporary transient water-feeding type shown in Fig. 4 of known such as same patent document 1.
In the device of this temporary transient water-feeding type, the fresh clean water supplied from clean water feedway is temporarily supplied to gas-liquid contact room.
In contrast, the clean water used of discharging from gas-liquid contact room is all expelled to device.
In addition, when generating clean water, also be there is the device clean water used of discharging from gas-liquid contact room being returned to the temporary transient water-feeding type of clean water feedway as a part for unboiled water in unboiled water purification at clean water feedway.
In addition, even the air-purifying humidification device of any one of these periodical feeding formulas and temporary transient water-feeding type, about the output of clean water being supplied to gas-liquid contact room, as the purifying property removed by water-soluble gas composition from handling object air, also the gas componant needed for acquisition is removed the necessary purification of efficiency by the necessary water yield as basic water amount.
And, the water yield after handling object air wetting to the necessary humidification of certain humidification state is added with the necessary water yield of above-mentioned purification by the necessary water yield, the output necessitated.
So, when handling object air be outer gas etc. there is the air of the state change change of air condition (process before), if the change of its state causes the necessary water yield of the necessary humidification of above-mentioned humidification to change, then the necessary output for the clean water of gas-liquid contact room also changes with the intensity of variation of the necessary water yield according to humidification.
But, in existing air-purifying humidification device, as the water yield of humidification, a certain size the humidification design water yield of sufficient safety coefficient is estimated in setting, and the water yield after being added by the necessary water yield using this humidification design water yield with the purification as basic water amount is as designed supply capacity.
And the output carrying out the clean water of this certain designed supply capacity to be supplied to continuously gas-liquid contact room necessarily operates.
That is, output is not adjusted according to humidification with the change of the necessary water yield.
By the way, the change of the necessary water yield of humidification of state change of handling object air is resulted from order to tackle, also consider that such as check processing is to ethereal air condition before treatment, and based on this detection air condition, change according to the state of handling object air the humidification caused and increase and decrease the output of adjustment for the clean water of gas-liquid contact room with the intensity of variation of the necessary water yield.
But, in this situation, due to it is not clear whether remove gas componant with the gas componant of necessity removing efficiency, thus for the removing process of gas componant, be difficult to obtain the good control result of precision.
Therefore, as above based on detecting in the output adjustment of air condition, easily alignment error etc. is produced.Even if if this alignment error causes creating the humidification water consumption part among adjustment output become temporarily not enough state relative to the humidification of the reality of each time point by the necessary water yield, then also become the state of supplementing this insufficient section from the purification water consumption part among adjustment output, a part for purification water consumption part and humidification water consumption part are together consumed in the humidification of handling object air.
Thus, gas componant removing efficiency (that is, purifying property) becomes the state lower than desirable value, causes the situation of the processed air that can not obtain necessary degree of purification.
In order to reliably avoid such situation, in this air-purifying humidification device, all the time, the output carrying out the clean water of excessive certain designed supply capacity to be supplied to continuously gas-liquid contact room as described above necessarily operates.

Patent document 1: Japanese Unexamined Patent Publication 2000-279741 publication.
Summary of the invention
The problem that invention will solve
But, in above-mentioned output necessarily operates, due to the clean water of excessive designed supply capacity is supplied to gas-liquid contact room continuously, thus, in the device of periodical feeding formula, also exist and circulation clean water is increased and the problem that increases of operating cost from the pump power that storage box is delivered to gas-liquid contact room.
In addition, in the device of temporary transient water-feeding type, due to the whole of the clean water used of discharging from gas-liquid contact room are expelled to outside device, thus the pump power not only fresh clean water being supplied to gas-liquid contact room increases, and the consumption of the fresh clean water of the pure water being supplied to gas-liquid contact room etc. increases, thus, there is the problem that operating cost increases further.
In view of these actual conditions, of the present invention theming as provides a kind of air-purifying humidification device, this air-purifying humidification device is by carrying out rational output adjustment, thus reliably and stably obtain required purifying property and required humidifying performance, enable output for the clean water of gas-liquid contact room for necessary relative to required gas componant removing efficiency and measure fully simultaneously, thereby, it is possible to effectively reduce operating cost.
For the scheme of dealing with problems
In order to form air-purifying humidification device as above, as the 1st with reference to forming, also can be following formation:
A kind of air-purifying humidification device, possesses gas-liquid contact room, and this gas-liquid contact room makes to be vented to indoor handling object air and carries out gas-liquid contact indoor with clean water,
By carrying out gas-liquid contact in this gas-liquid contact room and clean water, thus by the water miscible gas componant removing in handling object air by handling object purification of air, and, by handling object air wetting,
This air-purifying humidification device possesses displacement checkout gear, and this displacement checkout gear detects the displacement of the clean water used of discharging from above-mentioned gas-liquid contact room,
Further, possess control device, this control device adjusts the output for the clean water of above-mentioned gas-liquid contact room based on the detection displacement of above-mentioned displacement checkout gear and above-mentioned displacement is adjusted to setting displacement.
Namely, known, if the water quality being supplied to the clean water of gas-liquid contact room is identical, so, the gas componant removing efficiency of this air-purifying humidification device is by ratio (that is, the L/G value) decision of the air quantity of the water yield contributing to the purification of handling object air among the output for gas-liquid contact room and handling object air.
But, in this air-purifying humidification device, as mentioned above, if create the humidification of the humidification water consumption part among for the output of gas-liquid contact room relative to the reality of each time point becomes not enough state by the necessary water yield, then become its insufficient section and supplemented by the purification water consumption part among output and contribute to the state of the water shortage of the purification of handling object air.
In addition, on the contrary, if create the humidification of the humidification water consumption part among output relative to the reality of each time point become superfluous state by the necessary water yield, then the purification water consumption part one among its excess electron excess fraction and output coexist contribute to handling object air purification after discharge from gas-liquid contact room.
Namely, under certain output, if the state change etc. of handling object air makes the necessary water yield of humidification change, the water yield being consumed in the humidification of handling object air then among output preferentially self-adjusting is the water yield equal with the necessary water yield of humidification of the reality after change, thus, among output be not consumed in humidification but contribute to the purification of handling object air the water yield (that is, contribute to purify after from gas-liquid contact room discharge the water yield) change.
Relative to this, the above-mentioned 1st with reference in the air-purifying humidification device formed, adjusting output based on detecting displacement and displacement be adjusted in the process of setting displacement, as this setting displacement, preset and obtain required gas componant and remove the equal water yield of the necessary water yield of the necessary purification of efficiency.
Thus, according to the above-mentioned 1st with reference to the air-purifying humidification device formed, humidification with the change of the necessary water yield make the water yield being consumed in humidification among output preferentially self-adjusting be and the equal water yield of the necessary water yield of humidification after change, relative to this, also the necessary water yield of purification that the water yield (that is, becoming the water yield of the displacement from gas-liquid contact room) contributing to the purification of handling object air among using output sets as setting displacement can be maintained.
Thus, no matter the state change etc. of handling object air causes the necessary water yield of humidification to change, gas componant can be removed efficiency (purifying property) and be maintained desirable value, the degree of purification of processed air can be maintained necessary degree of purification.In addition, as described above relative to humidification with the change of the necessary water yield preferentially self-adjusting be consumed in the water yield of humidification, thus maintain humidifying performance.
And in addition, compared with the detection of the air condition such as humidity and temperature, the reliability of detection generally in accuracy of detection of displacement is high and be difficult to produce metrical error.So, if be as above based on the output adjustment detecting displacement, so also can avoid more reliably causing the aforesaid problem based on detecting in the output adjustment of air condition, that is, alignment error etc. cause gas componant to remove the situation of efficiency lower than desirable value.
Thus, according to the above-mentioned 1st with reference to the air-purifying humidification device formed, can reliably and stably obtain required purifying property and required humidifying performance, simultaneously, compared with the existing apparatus output that the clean water of excessive designed supply capacity is supplied to gas-liquid contact room continuously necessarily operated with employing, the output of the clean water for gas-liquid contact room can be reduced to effectively necessary relative to required gas componant removing efficiency and measure fully, thereby, it is possible to effectively reduce the operating cost of device.
In addition, as setting displacement, in fact preferably set and estimate some safety coefficients and ratio purifies by the necessary water yield water yield larger to a certain extent.But, even if in this case, and carry out compared with existing apparatus that output necessarily operates, also to reduce operating cost significantly.
By the way, the state change etc. of handling object air causes the necessary water yield of humidification to change, in contrast, in order to maintain required purifying property and required humidifying performance, also considers following output adjustment.
Namely, if it is excessively not enough that humidification makes the water yield contributing to the purification of handling object air among output produce with the change of the necessary water yield, the water-soluble gas constituent concentration (that is, absorbing gas composition concentration) of the clean water used of then discharging from gas-liquid contact room also changes.So, consider to detect the gas composition concentration from the discharge clean water of gas-liquid contact room, and automatically adjust the output of the clean water for gas-liquid contact room in the mode gas composition concentration of discharging clean water being maintained setting concentration based on this detectable concentration.
But, in water, the reliability of the detection of gas composition concentration generally in accuracy of detection is low and easily produce error, therefore, based on detecting in the output adjustment of gas composition concentration, still easily causing alignment error etc. and causing gas componant to remove the situation of efficiency lower than desirable value.
In this, if be the air-purifying humidification device that above-mentioned 1st reference adjusting output based on detecting displacement is formed, so, as mentioned above, can avoid more reliably causing such situation, thereby, it is possible to reliably and stably obtain required purifying property and required humidifying performance, effectively reduce the output of clean water simultaneously.
In addition, gas componant removing efficiency eta described herein is expressed from the next.
η=(Cai-Cao)/Cai
Wherein, Cai: the water-soluble gas constituent concentration of handling object air before treatment;
Cao: the water-soluble gas constituent concentration of the handling object air after process.
The above-mentioned 1st with reference in the enforcement formed, about the way of contact of clean water and handling object air, can adopt and in gas-liquid contact room, clean water is passed to flow down the surface with parts and with the mode under moisture film state flow, various ways of contact clean water being supplied to the mode possessing the aeration parts of the property of water-bearing and wettability being configured at gas-liquid contact room or the mode of clean water being sprayed with high-density state in gas-liquid contact room, the mode that these modes combined etc.
If the clean water used (for being supplied to the fresh clean water of gas-liquid contact room in temporary transient water-feeding type) is pure water or general running water or the water that can maintain roughly certain water quality by the purifying waste water of purifying such as filter etc., so, various clean water can be used.In addition, as clean water, the various aqueous solution that with the addition of medicine also can be used.
1st with reference to the air-purifying humidification device formed, at the air changed in the air condition moment before treatment of outer gas etc. as especially effective when handling object air.But the air that handling object air also can usually not change for air condition before treatment or not too change, even if in this case, the meaning of the state change of the handling object air of guarding against certain reason to cause also is effective.
In addition, the humidification reason of the change of the necessary water yield is not limited to the state change of handling object air, the change of the necessary water yield of humidification that also can cause for reason in addition, in this case, if be the air-purifying humidification device that the 1st reference is formed, so, also required purifying property can stably be maintained.
In order to form air-purifying humidification device, as the 2nd with reference to forming, also can be following formation:
Possess Wind volume detector, this Wind volume detector detects the ventilation for the handling object air of above-mentioned gas-liquid contact room,
Above-mentioned control device is the formation changing above-mentioned setting displacement based on the detection ventilation of this Wind volume detector.
Namely, gas componant removing efficiency (purifying property) as described above by as among output be not consumed in humidification but contribute to the ratio of the water yield (that is, becoming the water yield of displacement) of the purification of handling object air and the air quantity of handling object air L/G value decision.So, if for the handling object air of gas-liquid contact room ventilation (namely, the process air quantity of handling object air) change, then handling object air wetting is changed pro rata to the necessary water yield of the necessary humidification of certain humidification state, and the necessary water yield of gas componant removing efficiency (purifying property) necessary purification needed for obtaining also relevantly to change with certain.
Relative to this, if be that above-mentioned 2nd reference is formed, so, change to will set displacement based on detection ventilation, be present in the ventilation of handling object air and purification with certain the shutting mutually between the necessary water yield, using the water yield (reality under estimate the water yield of safety coefficient to a certain degree) equal with the necessary water yield of purification of ventilation of the handling object air corresponding to each time point as setting displacement.
If in advance like this, so relative to the change of the ventilation of handling object gas, can allow the water yield being consumed in the humidification of handling object air among output as described above preferentially self-adjusting be with the necessary water yield of the humidification of each time point (namely, the necessary water yield of humidification that changes pro rata along with ventilation change) the equal water yield, the water yield (becoming the water yield of displacement) contributing to the purification of handling object air simultaneously among output also automatically change to the necessary water yield of the purification of each time point (namely, along with ventilation change with certain necessary water yield of the relevant purification carrying out changing) the equal water yield.
Thus, no matter the ventilation change of handling object air, can both remove efficiency (purifying property) and be maintained desirable value, the degree of purification of processed air can be maintained necessary degree of purification by gas componant, in addition, also required humidifying performance can be maintained.
By the way, to detect the gas composition concentration (absorption gas composition concentration) of the discharge clean water from gas-liquid contact room as described above, when adjusting the output for the clean water of gas-liquid contact room based on this detectable concentration in the mode gas composition concentration of discharging clean water being maintained setting concentration, by means of only like this, also gas componant can be removed efficiency (purifying property) relative to the change of the ventilation of handling object air and be maintained desirable value, further, the humidifying performance needed for maintenance.
But also as mentioned above, in water, the reliability of the detection of gas composition concentration generally in accuracy of detection is low and easily produce metrical error.
But, if be the above-mentioned formation changed by setting displacement based on detecting ventilation, so, the reliability detected due to ventilation is high and be difficult to produce alignment error, thus can avoid more reliably causing gas componant removing efficiency relative to the ventilation change of handling object air the situation lower than desirable value.

In addition, the transversal ventilation direction along outer gas OA configures 2 side by side with proximity state and flows down medium 19, and water supply collector 20 is configured in the top that 2 flow down medium 19 minim gap each other.
That is, at this gas-liquid contactor 16, by mouthful 20a that drips from water supply collector 20 clean water W dripped to and flow down medium 19, thus the surface this clean water W that drips being passed to flow down multiple waveform plate-shaped members 22 of medium 19 respective with under moisture film state flow.
Thus, to flow down in the configuration space of medium 19 and device as gas-liquid contact room, make to carry out gas-liquid contact by the outer gas OA as handling object air in waveform plate-shaped member 22 gap each other with the clean water W of the moisture film state being in the process of flowing down, by this gas-liquid contact, thus the removing water miscible gas componant that comprises of outer gas OA and purify outer gas OA, and by this outer gas OA humidification extremely close to saturation state.
To drip the clean water W being supplied to and flowing down medium 19 as from flowing down collector 20, the pure water W temporarily supplied as fresh clean water for gas-liquid contactor 16, this pure water W are supplied by supplying water route 24 from the pure water production device 23 as clean water feedway by supply-water pump Pw.
That is had in one's care by drain pan 21 is expelled to outside from the clean water W ' (that is, absorbing the clean water used of gas componant) that flows down flowing down medium 19 by draining road 25.That is, this gas-liquid contactor 16 is temporary transient water-feeding type.
In the confession water route 24 from pure water production device 23, be equipped with the water supply flow regulating valve 26 fresh clean water W (pure water) for gas-liquid contactor 16 being adjusted to output Li, in addition, on the draining road 25 from gas-liquid contactor 16, be equipped with drain flow-meter 27, this drain flow-meter 27 is as the displacement checkout gear of the displacement Lo of the clean water W ' (pure water used) used detected from gas-liquid contactor 16 discharge.
Moreover, in addition, due to the behaviour in service according to object room 1 by the air quantity change etc. of outer for the adjustment being supplied to air conditioner 8 from investigation mission outside the city or town machine 7 gas OAs, thus ventilation Gi (in other words, the ventilation of the outer gas OA at the gas-liquid contactor 16 place) change of the outer gas OA at investigation mission outside the city or town machine 7 place.In contrast, at investigation mission outside the city or town machine 7, be equipped with air volume meter 28, this air volume meter 28 is as the Wind volume detector of the ventilation Gi of the outer gas OA of detection.
And, at this investigation mission outside the city or town machine 7, be equipped with changeable water supply controller 29, this changeable water supply controller 29 is as the control device automatically adjusting the output Li of the fresh clean water W (pure water) for gas-liquid contactor 16 based on the detection displacement Lo of these drain flow-meter 27 and the detection ventilation Gi of air volume meter 28.
Fig. 4 shows the material balance at gas-liquid contactor 16 place.Each symbol in figure represents following each value.
The output of Li: clean water W;
Lo: the displacement of the clean water W ' used;
Lh: add moisture relative to the outer gas OAs after the process of outer gas OA before treatment;
Gi: the ventilation of outer gas OA;
The water-soluble gas constituent concentration (≈ 0) of Cwi: supplying clean water W;
The water-soluble gas constituent concentration of Cwo: the clean water W ' used;
Cai: the water-soluble gas constituent concentration of outer gas OA before treatment;
Cao: the water-soluble gas constituent concentration of the outer gas OAs after process.
At this, when considering the material balance at gas-liquid contactor 16 place, because the material amount entering the water and air of gas-liquid contactor 16 is equal with the material amount of the water and air of discharging from gas-liquid contact room 16, thus following (formula 1) is set up.
Li × Cwi+Gi × Cai=Lo × Cwo+Gi × Cao+Lh × Cwi ... (formula 1).
In addition, be displacement Lo owing to deducting the water yield after adding moisture Lh from output Li, thus following (formula 2) is set up.
Li=Lh+Lo ... (formula 2).
And, if (formula 2) is substituted into (formula 1) and arranges (formula 1), then obtain following (formula 3).
Lo × (Cwi-Cwo)=Gi × (Cao-Cai) ... (formula 3).
In contrast, represent that the gas componant removing efficiency eta of the purifying property for outer gas OA of gas-liquid contactor 16 is represented by following (formula 4).
η=(Cai-Cao)/Cai ... (formula 4).
If above-mentioned (formula 3) substituted into and be somebody's turn to do (formula 4), then gas componant removing efficiency eta is represented by following (formula 5).
η=(Lo/Gi) × ((Cwo-Cwi)/Cai) ... (formula 5).
Be somebody's turn to do the water-soluble gas constituent concentration Cwo of the clean water W ' used of (formula 5), determined relative to the ratio (Lo/Gi) of outer gas ventilation Gi with the displacement L of the clean water W ' used by the equilibrium relation of water-soluble gas composition and water.If greatly (namely this become than Lo/Gi, when gas ventilation Gi is certain outside, displacement Lo becomes large), then the water-soluble gas constituent concentration Cwo of the clean water W ' used diminishes, and gas componant removing efficiency eta is passed along the direction of rising with linear relationship.
So, the principal element of domination gas componant removing efficiency eta in (formula 5), outside the water-soluble gas constituent concentration Cai of fixing before treatment outer gas OA and the water-soluble gas constituent concentration Cwi (≈ 0) of supplying clean water W, be Lo/Gi except the entry condition as air and water.
Namely, if the water quality being supplied to the clean water W of gas-liquid contactor 16 is identical (namely, Cwi=is certain), so, represent that the gas componant removing efficiency eta of purifying property is determined by the L/G value of the ratio as the air quantity (=ventilation Gi) for the water yield (=water yield) equal with displacement Lo contributing to the purification of outer gas OA among the output Li of gas-liquid contactor 16 and outer gas OA.
On the other hand, in this gas-liquid contactor 16, about the outer gas OA of regulation ventilation Gi, to obtain the necessary water yield Lj of the required gas componant removing necessary purification of efficiency eta as basic water amount, must using the water yield (Lj+Lh) after the outer gas OA humidification of handling object to the necessary humidification of certain humidification state is added with the necessary water yield Lj of this purification with necessary water yield Lh as output Li.
So, in the sufficient situation of output Li, in this gas-liquid contactor 16, no matter the state before treatment of outer gas OA, can both by the outer gas OA humidity close to saturation state (such as, relative humidity 95%) that stably humidification is extremely roughly certain.
This means, under certain output Li, if the state change etc. of outer gas OA before treatment makes the necessary water yield Lh of humidification change, the water yield being consumed in the humidification of outer gas OA then among output Li preferentially self-adjusting is the water yield equal with the necessary water yield Lh of humidification of the reality after change, thus, among output Li be not consumed in humidification but the water yield contributing to the purification of outer gas OA (namely, the displacement Lo discharged from gas-liquid contactor 16 after contributing to purifying) change, the water yield (=Lo) causing its purification to become the state of not enough (Lo<Lj) relative to above-mentioned purification or becomes superfluous state (Lo>Lj) with necessary water yield Lj.
In contrast, above-mentioned changeable water supply controller 29 is the formation of the control of following (1), (2) of carrying out as the output adjustment caused thus.
(1) the detection displacement Lo based on draining flowmeter 27 adjusts water supply flow regulating valve 26, thus the displacement Lo of the clean water W ' (pure water used) used discharged from gas-liquid contactor 16 is adjusted to setting displacement SLo.
(2) displacement SLo will be set according to the detection ventilation Gi of air volume meter 28 to change.Specifically, setting displacement SLo using the purification of the outer gas ventilation Gi for each time point with necessary water yield Lj as the benchmark water yield, the water yield of surplus will be estimated where necessary relative to this benchmark water yield as setting displacement SLo.
At this, as the intrinsic constant of device (namely, according to based on device shape contact coefficient and require removing efficiency eta etc. and different constants) L/G value be α when, can be represented the necessary water yield Lj of purification of the outer gas ventilation Gi for each time point by Lj=α × Gi, changeable water supply controller 29 determines the setting displacement SLo of each time point based on such related data 30.
Namely, no matter the state change of outer gas OA and air quantity change etc. make the necessary water yield Lh of humidification and the necessary water yield Lj change of purification, in addition, no matter the water yield being consumed in humidification as mentioned above among output Li preferentially self-adjusting is the water yield equal with the necessary water yield Lh of the humidification of each time point, controlled by the output of above-mentioned (1), (2), thus the water yield (that is, equal with the displacement Lo water yield) contributing to the purification of outer gas OA among output Li is adjusted be maintained the water yield equal with the necessary water yield Lj of the purification of each time point.Thus, do one's utmost to save the output Li for the fresh clean water W of gas-liquid contactor 16, Simultaneous Stabilization ground obtains for the purifying property needed for outer gas OA and required humidifying performance.
