BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 2.
As shown in FIGS. 1 and 2, the volatile gas adsorption / deodorization apparatus for organic solvents for nail art according to the present embodiment has a volatile gas suction head attached to the upper part of the volatile gas adsorption / deodorization treatment apparatus body. It has been. The suction head is attached by either a detachable or fixed method.

As shown in FIG. 1, the volatile gas adsorption / deodorization treatment apparatus main body 3 has the guide member 4, a dust collection filter 5, the organic solvent volatile gas adsorption filters 6 to 8, and the neutralizer 16 on the downstream side from the head. The suction / discharge device motor 10, the fan 11, the negative ion generator 12, and the discharge port 14 are arranged in this order.
The guide member 4 is configured such that the volatile gas is guided inside the guide member 4 by guide fins (not shown) so that dust and organic solvent can be adsorbed on the entire surfaces of the filters 5 to 8. As a result, the adsorption amount of each of the filters 5 to 8 is increased, the replacement time of the filters 5 to 8 is lengthened, and the use cost is reduced.

As shown in FIG. 3, the activated carbon filter is divided into a plurality of stages (in this embodiment, upper and lower stages 6, 7), and the activated carbon filter 6 in the upper stage has a larger activated carbon density than the activated carbon filter 7 in the lower stage. It is characterized by.
The upper activated carbon filter 6 is a high-concentration filter designed to increase the adhesion density of the organic solvent adsorbent, and is specially made for high-concentration use. Deodorization treatment is performed.
That is, the concentration of the organic solvent such as acrylic acid for nail art and acetone sent from the suction head 1 is very high, and is effectively adsorbed by the upper filter 6 of special adsorption.
The upper filter 6 is a functional powder sheet in which granular activated carbon is sandwiched between non-woven fabrics, which is a sheet-like material pleated, but is specially made by including an appropriate amount of granular activated carbon between the pleated weaves. It is a filter.
Further, the upper filter 6 is housed in a storage box (for example, a honeycomb) finely divided in the form of granular activated carbon or the pleated nonwoven fabric described above, and the upper and lower surfaces are made of thin paper that has good ventilation and is not easily torn. Suppressed filters are also used.

The lower activated carbon filter 7 is for medium concentration treatment, and the activated carbon is affixed to a nonwoven fabric and woven in a pleat like the upper activated carbon filter 6, but the amount of activated carbon is higher than that of the upper filter 6 for high concentration. Set it to a small amount when the concentration of volatile gas is reduced.
Furthermore, like the upper activated carbon filter 6, activated carbon is stored in a granular state in a finely divided storage box (for example, a honeycomb), and the upper and lower surfaces are made of a filter that is suppressed by thin paper that has good air permeability and is not easily torn. Sometimes.
Since the organic solvent volatile gas that has passed through the upper activated carbon filter 6 has been adsorbed considerably and its concentration has been reduced, it is very reasonable and costly to be treated with the lower activated carbon filter 7 for medium concentration treatment. Is also advantageous.
Accordingly, the activated carbon filters are arranged in consideration of the fact that the lifetimes of the upper activated carbon filter 6 and the lower activated carbon filter 7 are almost the same, and this arrangement is a rational and great feature.

Since the nail salon has many small spaces, it is one of the big issues to gather the adsorption / deodorization treatment device body 3 compactly. This is how the filter device can be gathered compactly and efficiently. It depends.
As one method for collecting the adsorption / deodorization treatment device body 3 in a compact manner, the upper activated carbon filter 6 and the lower activated carbon filter 7 have a feature that they are made compact by woven pleats, although the area is wide when expanded. is there.
Accordingly, the upper activated carbon filter 6 and the lower activated carbon filter 7 are housed in the adsorption / deodorization treatment device main body 3 in a space-efficient manner, and the adsorption / deodorization treatment device main body 3 can be manufactured in a compact manner. This is a major feature.
The amount of activated carbon is set to suit the purpose and is different for each. However, since the product is pleated, it has excellent air permeability and at the same time has a long contact time with gas and excellent adsorption efficiency. The upper-stage activated carbon filter 6 and the lower-stage activated carbon filter 7 are housed in a paper frame, and are designed so that they can be easily discarded or recycled.

The downstream chemical filter 8 is specially processed by impregnating the inorganic powder / amine compound into the nonwoven fabric, and is characterized by a special filter that has no other examples in the mixing ratio, and is thin and compact. It is summarized in.
The chemical filter 8 is characterized in that it aims to remove acetaldehyde contained in the nail organic solvent and other low-concentration organic solvents by chemical reaction, and the effect of adsorption is remarkable.
The chemical filter 8 is attached to a paper frame, and is different from a generally used metal frame (for example, AL) in which the filter is fitted, and can be discarded for each frame. .
Since the volatile gas sucked into the volatile gas adsorption / deodorization treatment apparatus main body 3 does not leak out of the filters 5 to 8 and does not pass through the filters 5 to 8, all of the filters 5 to 8 pass through. Give maximum consideration to sex.

As shown in FIG. 2 cross section AA, in order to prevent leakage from the following places (1), (2), (3), (4) where gaps may occur at the contact surfaces between parts, Sealing agent 13 is used on each contact surface to improve airtightness and to prevent leakage. That is, (1), each filter 5-8 is housed in a slide rail (5S-8S according to the filter number), but the clearance between the outer periphery of each filter 5-8 and the slide rail 5S-8S. .
(2) The slide rails 5S to 8S are attached to the slide rail attachment member 9, but the clearance between the slide rails 5S to 8S and the slide rail attachment member 9.
(3) Further, a gap between the slide rail mounting member 9 and the inner surface of the adsorption / deodorization device 3.
(4) In addition, leakage occurs between the front and rear surfaces of each filter and the inner surface of the adsorption / deodorization device 3, particularly between the filters 5-8 and the slide rails 5S-8S for storing the filter. In order to minimize the gap, the accuracy between the two is increased and set to be extremely narrow. Thus, in combination with the above, the volatile gas is prevented from being released downward without passing through the filter.
As above,
At least each filter 5-8 and each slidelay 5S-8S for filter attachment, each slidelay 5S-8S and slide rail attachment member 9, the inside of the attachment member 9 and the adsorption / deodorization apparatus main body 3, each filter and the above It is set so that it does not pass through the gap between the inner surface of the adsorption / deodorization device 3 and the like and is discharged from the discharge port 14 without being adsorbed / deodorized by the filters 5-8.

The performance of the motor 10 and the fan 11 of the suction / release device is determined in consideration of fan noise and the like, on the premise that an appropriate air volume necessary for the device is secured in order to sufficiently perform the adsorption / deodorization function.
That is, the air volume in the suction head 1 is such that the volatile gas in the room is discharged to the adsorption / deodorization treatment device main body 3 without delay, and the adsorption / deodorization treatment device main body 3 sufficiently performs the adsorption / deodorization function. Based on the above, the performance of the motor 3 and the fan 11 is determined so that the necessary air volume can be secured.
If the air volume at the head is larger than the appropriate amount, the adsorption by the special filter is not sufficiently performed and the function is not achieved.

Further, the suction head is attached to the volatile gas adsorption / deodorization apparatus main body 3, and the organic solvent volatile gas adsorption / deodorization apparatus system as a whole is compact.

Volatile gas forcibly sucked from the suction head is directly taken into the main body 12 of the adsorption / deodorization treatment device, and is adsorbed / deodorized through the filters 5 to 8 and the neutralizing agent 9. Then, it becomes odorless and harmless and is discharged from the outlet 14 by the fan 11.
