Description

  The present invention relates to a substance collection device for removing gas malodor and the like.

  In daily life and industrial activities, various deodorizing devices are known for removing malodors in gases.

  As a conventionally known deodorizing apparatus, (a) an absorbing substance such as activated carbon or silica gel is left in the gas, exposed, and the malodorous substance contained in the gas is absorbed by the absorbing substance, thereby causing bad odor. Deodorizing device that absorbs substances, (b) Deodorizing device that masks malodors by releasing fragrant substances in gas, (c) Gases containing malodorous substances such as water, alkalis, acids, etc. A deodorizing device that absorbs the malodorous substance in the liquid by passing it through the liquid atmosphere in which each malodorous substance is dissolved, (d) a deodorizing apparatus that absorbs the malodorous substance in the liquid impregnated with the resin material, etc. It has been.

Conventionally, in various fields, it is required to collect and concentrate substances contained in gas.
For example, in the analysis field, in order to analyze a specific substance contained in a gas, a material collection and concentration technique is required. In various industrial fields and environmental fields, exhaust gas and gas contained in the atmosphere are required. In order to remove unnecessary substances such as components, a technique for collecting and concentrating substances is required.

Conventionally, various deodorizing apparatuses for removing odors generated in general households and public toilets are also provided.
Conventionally known as a deodorizing device for toilets, (a) by allowing an adsorbent such as activated carbon or silica gel to stand and be exposed in the gas and adsorb the malodorous substance contained in the gas to the adsorbent There are known deodorizing apparatuses that adsorb substances that cause odors, and (b) deodorizing apparatuses that mask bad odors with fragrances by releasing highly aromatic substances into the gas.

Conventionally, in the analytical field, for example, gas substances are collected by an adsorbent in a column of a gas chromatograph.
For this, a material impregnated with a less volatile stationary phase liquid or an adsorbent such as activated carbon or alumina filled in glass or a metal capillary is used.

The adsorption phenomenon by this adsorbent varies depending on the nature of the adsorbent and the substance to be adsorbed and the solvent. For example, polar adsorbents such as silica gel and alumina are strong against strongly polar substances, and are slightly special nonpolar like activated carbon. The adsorbent exhibits a particularly strong affinity for aromatic compounds.
On the other hand, activated carbon is used as an adsorbent in the recovery of volatilized solvents at factories and waste disposal sites.

  Also, in the environmental field, it is necessary to collect and monitor harmful substances that accompany emission of exhaust gas. For example, in the case of measuring sulfur dioxide concentration in the atmosphere, the measurement gas contains hydrocarbons. In order to affect the measurement result of sulfur dioxide, an adsorbent for removing hydrocarbons is used in the measurement system.

  However, the conventional deodorizing apparatus has problems in terms of the amount of malodorous substance absorbed, the absorption efficiency, the period of use, and the like.

For example, in the deodorizing apparatus in which the absorbing material (a) is left in a gas, there is a problem that the absorbing amount of the absorbing material is small and it cannot withstand long-term use.
In addition, the deodorizing apparatus (b) has a limit in the amount of fragrance generated, so that there is a problem that the deodorizing effect is not maintained over long-term use.
Therefore, in the deodorizing apparatus of (a) and (b), it is necessary to frequently replenish the absorbing substance and the deodorizing substance. Therefore, the cost for maintaining the deodorizing effect of the deodorizing apparatus becomes high.

  Moreover, since the deodorizing apparatus using the scrubber of (c) has a low gas absorption efficiency in the liquid atmosphere, a large equipment is required to obtain a sufficient deodorizing effect, and the cost is increased.

Moreover, the liquid needs to be replenished to evaporate and vaporize and mix into the target gas, and the liquid gradually decreases.
In addition, the deodorization apparatus using the resin material of (d) has a problem in terms of gas absorption efficiency as in the case of (c), and the liquid impregnated in the resin material evaporates into the target gas. There is a problem that it cannot withstand long-term use because it vaporizes and the liquid gradually decreases.

Therefore, conventional deodorizing apparatuses have problems that the amount of malodorous substance absorbed is small, the absorption efficiency is low, and a long use period cannot be obtained.
As a gas purification device that solves these problems, a porous membrane with a large number of micropores is provided between the liquid and the gas, and the gas components contained in the gas are dissolved in the liquid through the porous membrane. An apparatus for preventing evaporation of liquid by the porous film has been proposed.

However, in a gas purification apparatus having a porous membrane, when there is a difference between the temperature of the gas and the temperature of the liquid, condensation occurs in the porous membrane, and the gas component dissolves in this condensation, resulting in a second bad odor source. There is a problem of fear.
That is, due to the temperature difference between the gas and the liquid, when moisture contained in the gas is condensed and attached to the surface of the porous membrane, the attached water droplets dissolve the gas component in the gas and become a source of bad odor, The efficiency of removing malodors will be reduced.

Moreover, in the gas purification apparatus provided with such a porous membrane, there exists a problem that a liquid evaporates and vaporizes and mixes in the target gas.
In particular, when the gas side is extremely dry with respect to the liquid, the liquid evaporates into the gas through the porous membrane, resulting in a shortage of liquid, or the amount of absorption and absorption efficiency of the substance in the gas. May decrease.

  On the other hand, in the above-described substance collection apparatus, it is required that the substance collection efficiency is high. In order to improve the collection efficiency, in the substance collection apparatus provided with the porous film, the porous film It is conceivable to increase the surface area of the gas and increase the contact area between the gas and the liquid.

However, the present inventors have confirmed through experiments that the contribution to the collection efficiency due to the increase in the surface area of the porous membrane is small.
In addition, increasing the surface area of the porous membrane increases the size of the collection device, which increases the production effort and cost.
As a measuring instrument for separating a gas substance in a gas, a separation device using a diffusion scrubber method has been proposed.

In this separation device, a tube made of a porous membrane of porous Teflon (PPTFE) is disposed in a cylindrical casing.
Then, the liquid is circulated between the casing and the tube, and the gas containing the gaseous substance and the particulate substance is circulated in the tube, so that the gaseous substance in the gas moves to the liquid side, and the gaseous substance Is separated from the gas.

That is, a minute hole is formed in the hydrophobic membrane forming the tube, and only the gaseous substance passes through the minute hole and is liquid because of the difference in diffusion coefficient between the particulate substance and the gaseous substance in the gas. To the side.
However, in such a separation device, since gas is circulated in the cylindrical tube, the gas processing capacity is low, and it can be used for a measuring device or the like that simply separates a gaseous substance. There is a problem that it is difficult to apply to the above.

That is, in such a separation apparatus, when the inner diameter of the tube is increased, the separation efficiency of the gaseous substance is lowered, and it is necessary to reduce the wind speed of the gas passing through the tube.
For example, in a tube having an inner diameter of 9 mm, the separation efficiency does not exceed 90% unless the wind speed is reduced to 13 cm / s, and decreases to about 80% when it is 26 cm / s.
On the other hand, when the inner diameter is 4 mm, it is 96% at 26 cm / s, 93% at 66 cm / s, and 82% at 130 cm / s, making it possible to select a wind speed that is about 5 times that of a 9 mm device. Become.

Further, as is clear from the Gormley-Kennedy empirical formula, it is difficult to secure a separation efficiency of 95% or more with the conventional separation apparatus unless the tube length is 500 mm or more.
The air volume at this time is 1000 cc / min and the wind speed is about 130 cm / s, and the processing air volume is too small to be applied to a general air conditioner or the like.

Here, even if the processing air volume is increased at the expense of separation efficiency, 2000 cc / min is the limit.
In such a separation device, the inner diameter of the tube is reduced, so that the pressure loss is increased and the power cost is increased.
Moreover, since the thickness of the tube is as thin as 0.5 mm, for example, when the gas flow rate is increased, stress acts on the joint portion between the tube and the casing, and there is a possibility that breakage or peeling of the bonded portion occurs.

Furthermore, when a large number of tubes are used, the tubes are arranged in a lattice pattern in the casing. From the viewpoint of manufacturing, the tube opening ratio at the cross-sectional portion is only about 28%, and the gas ventilation is performed. Compared to the section (piping, duct), a cross-sectional area of about 3 times is required.
On the other hand, conventional toilet deodorizers have problems in terms of the amount of absorption of harmful substances such as malodorous substances, absorption efficiency, and the period of use.

For example, in the deodorizing apparatus in which the adsorbing substance (a) described above is left in the gas, there is a problem that the adsorbing amount of the adsorbing substance is small and it cannot withstand long-term use, and also in the deodorizing apparatus (b) Since there is a limit to the amount of fragrance generated, there is a problem that the deodorizing effect is not sustained over a long period of use.
Therefore, in the conventional deodorizing apparatus for toilets, it is necessary to frequently replenish adsorbing substances and deodorizing substances, which increases the cost for maintaining the deodorizing effect of the deodorizing apparatus.

Moreover, although the substance used for these deodorizing apparatuses is usually installed in the toilet room, the source of the odor in the toilet is the inside of the toilet where excrement is excreted and diffuses from the excrement into the toilet room. .
Therefore, what arrange | positions an adsorbent and a fragrance | flavor in a toilet room like the conventional deodorizing apparatus deodorizes the odor diffused in the room, and there also exists a problem that deodorizing efficiency is bad.

As a means for collecting a specific substance in a gas, a substance collecting apparatus using a diffusion phenomenon from a gas to a liquid has been proposed.
This substance collection device makes a gas and a liquid contact with each other through a porous membrane, and diffuses and dissolves a specific gas substance in the gas into the liquid (solvent).
For example, when the formaldehyde is collected with distilled water, 99% is obtained as the collection rate of the substance collection device.

However, in such a material collection device, there is a problem that the gas substance is dissolved in the liquid and the collection rate of the gas substance is lowered when the concentration is increased, and cannot be collected when the saturation solubility is exceeded. .
In addition, there is a problem that a phenomenon occurs in which the gas substance collected in the liquid is released into the gas.

For this reason, although it is necessary to circulate a liquid and to suppress an increase in concentration, there is a problem that the use of the substance collection device is restricted in an environment where it is difficult to install a solvent circulation facility.
On the other hand, in the conventional substance collection device, as described above, an adsorbent is mainly used in a field that requires collection and concentration of substances and a field that requires removal of unnecessary substances.

However, in order to separate a target substance from a gas containing a plurality of gas substances, an adsorbent corresponding to each substance is required. However, if the adsorbent is expensive and if a plurality of adsorbents are used, the interaction And there was a problem that the collection efficiency was lowered.
Furthermore, when it is necessary to recover the collected substance, there has been a problem that the processing is complicated, for example, physical conditions such as pressure and temperature are given to the adsorbent and the solvent is absorbed.

  The present invention has been made to solve such conventional problems, and has an object to provide a substance collection device capable of increasing the absorption amount and absorption efficiency and improving the sustainability of the deodorizing effect. To do.

The diameter of the micropore 32 is actually a size corresponding to the size of the molecules of the gas component and not visible, but is enlarged and schematically shown in the drawing.
In FIG. 12, the micropores of the porous film are omitted.
The outer tube 34 is not a porous membrane, and no gas or liquid flows through the tube wall, and the gas or liquid is held inside the outer tube 34.

After flowing between the hydrophobic membranes 227 of the diffusion scrubber element 223, it flows into the hollow hole 239 a of the hollow bolt 239 from the liquid circulation hole 225 f formed on the opposite side of the frame member 225, and flows out from the liquid outflow joint 221. .

  Then, while the gas containing the gaseous pollutant passes through the gas flow part 215, the gaseous pollutant moves to the liquid side of the adjacent liquid flow part 217 through the hydrophobic film 227 by the diffusion scrubber method. Contaminants are removed from the gas.

  In the gaseous pollutant removal apparatus configured as described above, the gas circulation unit 215 through which the gas is circulated and the liquid circulation unit 217 through which the liquid is circulated are alternately stacked and the gas circulation unit 215 is disposed. Since the hydrophobic film 227 is disposed between the liquid flow part 217 and the liquid circulation part 217, the processing efficiency per unit volume of the apparatus can be significantly improved as compared with the conventional apparatus.

That is, in the separation apparatus as shown in FIG. 51, if the inner diameter of the tube 202 in the cylindrical casing 201 is increased, the separation efficiency of the gas substance is lowered. Therefore, it is necessary to reduce the inner diameter of the tube 202, and the processing capacity is reduced. In order to improve, it is necessary to arrange many tubes 202.
If a large number of tubes 202 are arranged in this way, the opening ratio of the tube 202 at the cross-sectional portion is only about 28%, and the cross-sectional area is about three times that of the gas ventilation portion (pipe, duct). It becomes necessary and the apparatus becomes very large.

On the other hand, in the gas purification device described above, when the thickness H of the gas flow part 215, that is, the distance between the hydrophobic films 227 arranged on both sides of the gas flow part 215 is set to 2 mm, for example, as shown in FIG. The same performance as that of the 4 mm tube 2 can be obtained.
Since the gas flow part 215 has a long rectangular cross section, for example, by setting the gas flow part 215 and the liquid flow part 217 to the same thickness H, the opening ratio of the gas flow part 215 is 50%. It becomes possible to increase to the extent.

In the above-described embodiment, the thickness H of the gas flow part 215 is larger than the thickness of the liquid flow part 217, and the opening ratio of the gas flow part 215 is 70% or more.
Therefore, the apparatus can be made very small, and the processing efficiency per unit volume of the apparatus can be greatly increased as compared with the prior art.
Further, since the deformation preventing means including the net member 229 and the separator 231 for preventing deformation of the hydrophobic film 227 toward the gas flow part 215 is arranged on the gas flow part 215 side of the hydrophobic film 227, the gas flow part 215. And the liquid circulation part 217 can reliably prevent the hydrophobic membrane 227 from being deformed toward the gas circulation part 215.

  Further, in the above-described apparatus for removing gaseous pollutants, the liquid circulation part 217 is formed by the frame member 225 having the frame part 225a formed on the outer periphery, and the gas circulation part 215 is integrally formed with the frame member 225. Since it is formed by the part 225b, the liquid circulation part 217 and the gas circulation part 215 can be configured easily and reliably.

Since the liquid flow passage 225f is formed in the frame member 225, the liquid can be easily and reliably supplied to the liquid circulation portion 217.
Further, in the gas purification device described above, the diffusion scrubber elements 223 are stacked to form the core portion 213. Therefore, by increasing or decreasing the number of diffusion scrubber elements 223, an apparatus having a desired processing capability can be easily obtained. Can be obtained.

  In the above-described embodiment, the example in which the blind plug 241 is screwed into the joint 243 at the lower end of the hollow bolt 239 has been described. However, the present invention is not limited to such an embodiment. Instead, the pipe joint may be screwed to allow the liquid to flow in or out from above and below the hollow bolt 239, or the pipe may be connected to another device via the pipe joint.

Furthermore, in the above-described embodiment, the example in which the separator 231 is formed in a wave shape has been described. However, the present invention is not limited to such an embodiment, and for example, gas can pass through like a punching metal or a mesh material. You may form in a grid | lattice form etc.
Thus, by forming the separator so that the gas can pass therethrough, the spaces on both sides of the separator communicate with each other, the gas can be transmitted and received, the generation of turbulence is promoted, and the gas liquid to be collected The contact efficiency to the distribution part can be improved.

In the above-described embodiment, an example in which a plurality of gas circulation portions and liquid circulation portions are alternately laminated has been described. However, the present invention is not limited to such an embodiment, and only one set is laminated. Also good.
FIG. 53 shows an example in which the above-described gas purification device (hereinafter referred to as a diffusion scrubber device) is used in, for example, an external air conditioner for a clean room. Air A from the outside is filtered by the medium performance filter 251. Then, it flows into the diffusion scrubber device 253.

Gaseous contaminants are removed by the diffusion scrubber device 253 and supplied to the clean room via a dehumidifier 255 and a fan 257 that are formed of cooling coils.
In this example, the diffusion scrubber device 253 is provided with a circulation pipe 259 for circulating the liquid to the liquid circulation part 217, and a circulation pump 261 is disposed in the circulation pipe 259.

In addition, a recovery unit 263 that recovers gaseous contaminants that have moved to the liquid side is disposed in the circulation pipe 259.
An adsorbent such as an ion exchange resin is accommodated in the recovery device 263.
A replenishment tank 265 for replenishing a liquid such as pure water is disposed in the diffusion scrubber device 253.

In the above-described diffusion scrubber device 253, the circulation pipe 259 that circulates the liquid to the liquid circulation part 217 and the recovery unit 263 that recovers the gaseous pollutant that has moved to the liquid side are disposed. A reduction in separation efficiency due to an increase in the concentration of can be avoided.
That is, the diffusion scrubber 253 described above, SO _x gas, NO ₃ gas, NH ₃ gas, HCl, HNO _3, HF, formic acid, acetic acid, acidic gases such as methylamine or, when used for the removal of alkaline gas Are present as ions in the collected water, and their concentration increases.

Therefore, as described above, by providing the recovery device 263 in which an adsorbent such as an ion exchange resin is accommodated, ions are adsorbed and the liquid concentration is lowered. Therefore, the operation is continued while maintaining high separation efficiency. Can do.
In addition, when using for removal of organic gas, formaldehyde, etc., these can be removed by using adsorption agents and chemical reaction agents, such as activated carbon, for the recovery device 263.

In addition, since the replenishment tank 265 for replenishing the liquid is disposed, the amount of liquid flowing through the liquid circulation unit 217 can be ensured.
In this example, the liquid level and salt concentration in the diffusion scrubber device 253 are constantly monitored. When the liquid level decreases or the salt concentration increases, the on-off valve 267 is opened and the liquid in the replenishing tank 265 is opened. Is supplied to the circulation pipe 259.

And since the dehumidifier 255 which dehumidifies the gas from the gas distribution part 215 was arrange | positioned in the external air handler, the liquid component which moved to the gas side can be removed.
That is, when the liquid used for the diffusion scrubber device 253 is water or an aqueous solution, moisture moves to the gas side, but this moisture can be removed reliably.

The diffusion scrubber device 253 described above has the advantage that it can remove gaseous pollutants in the gas with a stable performance for a long time just by replenishing the liquid to be used, and the running cost is low and the maintenance is easy. Have.
That is, the conventional technology for removing gaseous pollutants in a gas with a chemical filter has problems that the filter is expensive, has a short life, and becomes industrial waste. However, the diffusion scrubber device 253 described above has such a problem. The problem can be solved.

  Moreover, in the external air conditioner using the conventional air washer, since the flow path of water is opened with respect to the air flow path, it is necessary to consider various germs. However, in the diffusion scrubber device 253 described above, The liquid and the gas are completely separated through the membrane 227, and such consideration can be eliminated.

In addition, by making the above-mentioned diffusion scrubber device into a small unit, it can be used as an air cleaner or a removal device for the purpose of removing harmful components such as formaldehyde in general households.
In this case, the removal performance is maintained for a long time just by replenishing tap water, so that anyone can easily use it.

In addition, the removal object substance of the diffusion scrubber apparatus described above is, for example, formaldehyde (HCHO), sulfur oxide (SO _x ), ammonia (NH ₃ ), acetaldehyde (CH ₃ CHO), It is a water-soluble gas such as HCl, HNO ₃ , HF, formic acid, acetic acid, and methylamine.
And although substances other than water are rarely used for the liquid, for example, an acetonitrile solution can be used for high concentration treatment of formaldehyde.

The target buildings include plywood warehouses, food warehouses, hospitals, etc., in addition to clean rooms.
For indoor air with high concentration of formaldehyde such as plywood warehouse, the removal efficiency of the chemical filter is low and there is no effective removal device. Therefore, the diffusion scrubber device described above is very effective.

Also, even in a general building environment, adverse effects on residents can be reduced by installing and operating a portable diffusion scrubber device for a short period of time with a high formaldehyde concentration immediately after construction.
In the above-described example, an example in which the diffusion scrubber device 253 is disposed in an external air conditioner of a clean room has been described. However, gaseous contaminants in the air can be removed by incorporating the diffusion scrubber device 253 into an air conditioner or an air conditioning duct. .

  In the above-described example, the example in which the liquid is automatically supplied from the replenishing tank 265 has been described. However, the full tank may be maintained by simply disposing the replenishing tank above the core portion 213.

Moreover, in the deodorizing apparatus having the above-described configuration, the flow direction of the liquid and the gas can be the same direction or the reverse direction.

FIG. 68 shows a fourteenth embodiment of a substance collection device of the present invention.
The substance collection device according to this embodiment includes an inner tube A1 made of a cylindrical porous film, a substance collection device made up of an outer tube A2 and a lid A3 disposed outside the inner tube A1, and the outer tube A2. A detector A5a for detecting a chemical amount or a physical amount of the liquid A4 disposed between the inner tube A1 and the outer tube A2, and a signal converter A5b for converting the output into a predetermined output signal; The monitor A5 includes an output unit A5c for instructing or recording the output signal.

As the monitor A5, an electric conductivity meter, a PH meter, a turbidity meter, an ion concentration meter, or the like is used according to the chemical quantity or physical quantity related to the concentration of the gas substance of the liquid A4.
In the above configuration, although not shown, a pump is disposed before the inlet A3a or after the outlet A3b so that a gas containing a gas substance flows in the direction of the arrow A and dissolves the target gas substance in the direction of the arrow B. Shed.

For the inner tube A1, a porous film having the properties of the liquid or a porous film that has been subjected to a surface treatment for providing a hydrophobic organic solvent is used.
FIG. 69 shows a state in which the gas substance A11a (● mark) in the gas is dissolved in the liquid via the porous film A12 corresponding to the inner tube A1 of the substance collection device.
The gas substance A11a in the gas A11 containing the mixed gas substance diffuses into the micropores A12a of the porous film A12 and dissolves in the liquid. However, the gas substance A11b (◯ mark) is insoluble in the liquid, so the gas A11 Stay inside.

As a specific example, a case where methyl acetate gas is collected will be described.
68. By using porous Teflon (PPTFE) having hydrophobicity in the porous membrane of the material collection device of FIG. 68 and distilled water as the liquid A4, methyl acetate gas is dissolved in distilled water up to a maximum of 24.5 wt%. be able to.
This aqueous solution becomes an electrolyte solution and exhibits conductivity, and its electrical conductivity is a function of methyl acetate contained in the aqueous solution, and the solubility of methyl acetate can be known by measuring the electrical conductivity.

For example, the electrical conductivity of a 24.5 wt% aqueous methyl acetate solution is 3.4 × 10 ⁻⁶ S / cm (at 20 ° C.).
Therefore, if the collection efficiency with respect to the concentration of the aqueous methyl acetate solution is obtained in advance, the collection efficiency at that time can be known by measuring the electrical conductivity.

FIG. 70 shows a schematic configuration diagram of an electric conductivity meter used for the monitor A5.
In the figure, symbol A9 is a platinum electrode immersed in the liquid to be measured, through which a current I1 flows, and this current I1 flows to the cross coil A6a.
In the other coil A6b, a current I2 of the galvanometer shunt of the bridge circuit constituted by the thermal resistors A7a and A7b and the resistors A8a and A8b flows.

Since both the currents I1 and I2 change depending on the temperature of the liquid, compensation for the temperature of the liquid to be measured is performed.
The concentration can be obtained from the electric conductivity measured by such an electric conductivity meter, and the collection efficiency at that time can be grasped. By changing the liquid before the solubility reaches saturation, the collection efficiency can be lowered. Can be prevented.

As shown in FIG. 71, the relationship between the concentration of an aqueous solution in which a general target gas is dissolved and the electric conductivity is not a uniform proportional relationship. If the concentration exceeds a certain value, the electric conductivity increases with increasing concentration. There are many things that fall.
Therefore, there are two concentration values for the electrical conductivity of the liquid having the peak value.

In such a case, by using a recorder for the output part A5c in FIG. 68, the concentration with respect to the electrical conductivity at that time can be known.
FIG. 72 shows the configuration of the fifteenth embodiment of the substance collection device of the present invention.
Components having the same functions as those in FIG. 68 are denoted by the same reference numerals.

The monitor A5 includes a detector A5a, a data processing unit A5d, and an output unit A5c.
When an electric conductivity meter is used for the monitor A5, the relational expression between the concentration of the liquid dissolving the gas substance collected in advance and the electric conductivity is stored in the data processing device A5d. Compared with the signal, the concentration at that time can be obtained.

When this concentration reaches the set value, an alarm is issued, and the valve A16 is opened by a signal from the output unit A5c to discharge the liquid to the tank A13.
Next, the valve A16 is closed, the valve A17 is opened, the liquid in the substance collection device A10 is replaced, and the collection operation is repeated again.
By this operation, the gas substance can be collected without lowering the collection efficiency even in an environment where no circulation facility is provided.

FIG. 73 shows a sixteenth embodiment of the substance collection device of the present invention, and FIGS. 74 and 75 show a gas substance absorption liquid box provided with a porous membrane used in the substance collection device. 1 is a schematic configuration diagram of a liquid box (hereinafter referred to as a liquid box).
As shown in FIG. 73, the substance collection device of this embodiment is configured to separate and collect a liquid box 424 (consisting of 424a, 424b, 424c, and 424d) for absorbing a target gas substance in a container 425. Are provided, and an inlet 426 and an outlet 427 are provided for circulating gas in the direction of the arrow.

The liquid box shown in FIG. 74 has a configuration in which one surface of the container 414 that can accommodate the liquid 413 is an open surface, the open surface is closed with a porous film 411, and the liquid 413 is contained inside.
In FIG. 74, a portion indicated by reference numeral 412 indicates a micropore provided in the porous film 411.

The diameter of the micropore 412 is actually about the size of the molecule of the gas substance, but is enlarged and schematically shown for explanation.
The micropores 412 provided in the porous membrane 411 having this configuration are formed so as to pass between both surfaces of the membrane.
The liquid 413 provided in the container 414 has a property of dissolving the gas substance 415 in the gas, and comes into contact with the gas side through the micropores 412 of the porous film 411.

When the gas substance 415 comes into contact with the liquid 413 through the micropores 412, it diffuses into the liquid 413 and dissolves.
On the other hand, since the porous film 411 has a sparse property with respect to the liquid 413, the liquid 413 is substantially separated from the gas side by the porous film 411 and leaks to the gas side. There is no.

Therefore, only the movement of the gas substance from the gas side to the liquid side occurs between the gas side and the liquid side, whereby the target gas substance can be recovered into the liquid.
The liquid box in FIG. 75 has a configuration in which a porous film 411 is provided on both surfaces of a container 414, and the other configuration is the same as the configuration shown in FIG.
75, the area where the liquid 413 contacts the gas side can be increased, and the absorption efficiency can be increased.

As the porous film 411 in FIGS. 74 and 75, a hydrophobic (or water-repellent) or oleophobic (or oil-repellent) film can be used.
In the case where the porous film 411 is formed of a hydrophobic polymer film (for example, porous Teflon (PPTFE)), water can be used as the liquid 413 in which the gas substance 415 is dissolved.

  In addition, an oil-based liquid such as an organic solvent can be used as the liquid 413 for dissolving the gas substance 415 by subjecting the porous film 411 to an oleophobic (or oil-repellent) surface treatment.

A method of separating and collecting the gas substance from a gas containing methyl acetate and methyl chloroform gas substances using the substance collecting apparatus having the above-described configuration will be described.
73, distilled water is used for the liquid 403 in the liquid box 424a, a hydrophobic film (eg, porous Teflon (PPTFE)) is used for the porous film, alcohol or ether is used for the liquid 403 of the liquid box 424b, As the membrane, an oleophobic organic solvent membrane having a property of being sparse to alcohol or ether (for example, a fluorine compound membrane subjected to surface treatment) is used, and gaseous substances such as methyl acetate and methyl chloroform are introduced from the inlet 426. The contained gas flows in and flows out from the outlet 427.

The methyl acetate gas in the gas is dissolved in distilled water, which is a liquid, through the porous membrane of the liquid box 424a.
The methyl chloroform gas is dissolved in liquid alcohol or ether through the porous membrane of the liquid box 424b.
Further, when separating more kinds of gas substances, it is possible to increase the number of liquid boxes capable of absorbing the gas substances by the number of kinds.

In the embodiment of FIG. 73, since the liquid boxes 424a, 424b, 424c, and 424d are accommodated, the separation and collection of a maximum of four kinds of gas substances can be performed by using the liquid corresponding to the target gas substance and the porous membrane. It can be performed.
FIG. 76 shows the configuration of the seventeenth embodiment using a cylindrical porous membrane. FIGS. 77 and 78 show the function of the cylindrical porous membrane used in the substance collection device. It is the schematic perspective view and sectional drawing for demonstrating.

In FIG. 76, a plurality of pipes 431 and 432 that are combined with the planar porous film used in the sixteenth embodiment are combined and penetrated into a container 435.
The container 435 is divided into two independent containers 435a and 435b by a partition wall 436. The liquid 433 flows from the inlet 437 through the outlet 438 in the direction of arrow B, and the liquid 434 flows from the inlet 439 through the outlet 440. Flow in the direction of arrow C.

In FIG. 77, a portion indicated by reference numeral 431a indicates a micropore provided in the porous tube 431 formed of a porous film.
The diameter of the minute hole 431a is actually a size corresponding to the size of the molecule of the gas substance and not visible.
In FIG. 78, the micropores of the porous film are omitted.

Further, the container 435 is not a porous film, and no gas or liquid flows through the tube wall, and the gas or liquid is held inside the container 435.
In the double pipe, a gas containing a gas substance to be collected is flowed in the porous pipe 431 in the direction indicated by the arrow A (FIGS. 77 and 78), and the gas substance is placed between the porous pipe 431 and the container 435. When a liquid serving as a dissolving solvent is flowed, the liquid and the gas in the double tube come into contact with each other with the porous film forming the porous tube 431 interposed therebetween.

As described in the sixteenth embodiment, the gas substance in the gas diffuses and dissolves in the liquid.
As a result, the target gas substance can be collected.
