In FIG. 9, a spray device 26 is provided in the exhaust passage 14. A liquid tank 27 containing a liquid having the property of absorbing odor components is provided below the exhaust passage 14, and this liquid is heated by ultrasonic vibration f-28 as a spraying means commonly used in humidifiers and the like.
This atomized liquid absorbs the odor components.

In this case, the liquid in the liquid tank 27 decreases over time, but it can be replenished. Replenishment may be performed automatically. For example, a level sensor may be provided in the liquid tank 27, and when the liquid level drops below this level sensor, replenishment may be performed from a separately arranged replenishment tank using a pump or the like. You may also do so.

In FIG. 10, a spray 29 is used as the spray device 26, and a rotary humidifier or the like may also be used.

There is.

The storage tank 11 is sealed with a lid 13, and the odor will not come out unless A13 is opened.

When dissolving the processing liquid 12, the storage tank 11
When the lid 13 is opened as shown in FIG. 18 when inspecting the inside, the spray device 26 sprays deodorizing liquid in the form of a mist. Therefore, the odor generated from the processing liquid 12 is deodorized before it is released to the outside.

Then, when dissolving the processing liquid 12, as shown in FIG. 19, when the dissolution kit 35 is placed on the processing agent receiving plate 34, the spray of the deodorizing liquid is stopped. Until the dissolving kit 35 is placed on the treatment agent receiving plate 34, the odor will come out through the gap, so the deodorizing liquid is sprayed periodically or when the gas concentration reaches a certain level by detecting the gas concentration.

When the dissolution kit 35 is lifted, the deodorizing liquid is sprayed again as shown in Fig. 20, and when the cover 13 is closed, the spraying stops as shown in Fig. 21 and the dissolution is completed. do.

In this way, the treatment liquid 12 is dissolved and the deodorizing liquid is sprayed, and the spraying is turned on and off by, for example, electrical or mechanical means.

In addition, instead of the air sole type, other L-stages can also be used, such as using ultrasonic oscillation r to spray the deodorizing aqueous solution by ultra-F'r'a vibration.

Furthermore, in addition to the above, activated alumina, ferrous sulfate and mono-ascorbic acid mixture are used as odor adsorbents (deodorizers) as the deodorizing stage 15, and KGC used in the Sakaki type gas mask R-3 manufactured by Koken Co., Ltd. - Type 1 absorption, as well as KYMCO (registered trademark) manufactured by American Drug Corporation as a deodorizing agent for refrigerators, Nonsumel (registered trademark) manufactured by Yamamoto Co., Ltd., and ANICO (registered trademark) manufactured by Morishita Jintan Co., Ltd. as a multifunctional adsorbent. trademark) etc. can be used.

It should be noted that the deodorizing means may be the same as those used in the above embodiment (a plurality of deodorizing means may be combined at will).

Next, an example of deodorization according to the present invention will be shown below.

First, with a 50fi liquid storage tank filled with 20u of photographic fixer, the air inside the tank was sucked out with an exhaust fan and measured using a gas detection tube (manufactured by Kitazawa Sangyo Co., Ltd.). The measurement results were obtained.

Measured gas concentration Acetic acid scum: 80PPM Sulfur acid gas: 40PPM It is. This gas concentration has a pungent odor.

(1) Air inside the liquid storage tank at 100 It/m
15 cm in diameter as a deodorizing means by suctioning at a ratio of
When air was passed through a 2 cm thick breathable filter impregnated with water, the measured gas concentrations were reduced to 25 PPM for acetic acid gas and 19 PPM for sour acid gas.

(2) Air inside the liquid storage tank to 100. A vacuum cleaner with a diameter of 15 cm and a thickness of 2 cm is used as a deodorizing means by suctioning at a rate of M/min.
m permeable filter with sodium carbonate, pH
When air was passed through the water soaked in alkaline water, the measured gas concentrations were further reduced to 13 PPM for acetic acid gas and 8 PPM for sulfite gas.

(3) The gas concentration in the liquid storage tank is 100%
By suctioning at the rate of It/min,
After 3 hours, the amount decreased to 5 PPM for acetic acid scum and 2 PPM for sulfite gas.

When this air is deodorized under the conditions (2), it further decreases to acetic acid scum: 0.8 PPM and sulfur acid gas: 0.3 PPM, and the emitted air has almost no odor.

As described above, by continuous suction deodorization, the odor is significantly reduced, and by applying this invention, the irritating odor generated from the liquid storage tank can be eliminated. Furthermore, because the gas concentration inside the liquid storage tank is reduced and the air inside is sucked, there is almost no odor even when the outer lid is opened.

(Effects of the Invention) As described above, this invention removes odors of the liquid in the liquid storage device, such as odors of flowing acid gas, acetic acid gas, and ammonia gas, in one stage of deodorization. Since unpleasant odors are no longer emitted from the air, the flexibility of installation location is increased.

Therefore, for example, if the developing device is refilled with processing liquid, the developing device can be installed not in a darkroom but in an X-ray photography room, operating room, photo shop, etc. of a hospital.
