The present invention is to provide a in the above-mentioned conventional example Kaoru
When the aroma generator is installed in the discharge pipe and the air compressor is operated, the function of the aroma generator is rapidly deteriorated. What happens is that when the pressure is increased by the air compressor, the temperature of the compressed air reaches 180 ° C to 200 ° C when the pressure is increased to 7 kg / cm ² in the air compressor using the reciprocating air compressor.
Further, in the screw compressor, the temperature of the compressed air rises to about 80 ° C. Therefore, even if the air is cooled by the aftercooler, the temperature of the compressed air becomes, for example, about 30 ° C., and the aroma is generated.
Due to the structure of the vessel, it depends on the pressure, flow rate, and temperature of compressed air.
Due to the generation of fragrance and the rise in temperature, the amount of fragrance decreases sharply, and at the same time, a strong scent appears at first, but the odor disappears in a short time. Further, since the temperature is lowered from the compressed state, the condensed water adheres to the fragrance and not only the scent becomes light, but also the scent changes. Therefore, it is necessary to replace the fragrance in the fragrance generator in a short time, resulting in a large amount of labor for replacement and a large amount of expensive fragrance.

The present invention solves the above-mentioned problems of the aroma device of an air compressor in which an aroma generating device is interposed in the discharge pipe of the air compressor, and the aroma agent in the aroma generator is effectively used to improve the sustainability of the air. An object is to provide an aroma device for a compressor.

When the fragrance in the fragrance generator in the prior art is replaced, in the case of a liquid fragrance, a larger volume of fragrance is discharged than the calculated volume of fragrance consumed. It When this fragrance is observed in the case of a liquid, it is recognized that water is added. When the fragrance is granular, the surface of the discarded solid fragrance taken out for replacement is wet with water.

It is considered that such a phenomenon is caused by cooling and condensing the discharge air whose temperature is increased by the air compressor, and the diffuser in the aroma generator or the compressed air passing through the bypass circuit is cooled and the compressed air It is possible that water vapor condenses. Secondly, since the compressed air contains water vapor, the generated fragrance fine particles flow while being mixed with the compressed air, so that the moisture condensed from the steam by being sequentially cooled wraps around the fragrance fine particles, and the fragrance released with great care. It is considered that the components also do not act effectively, or that the fragrance generating ability is lowered by mixing the fragrance fine particles with water.

When compressed by the air compressor, the water vapor in the atmosphere changes into water and saturated water vapor according to the compression ratio. That is, drain water is produced. For example, if a compressor of 10 to 15 horsepower continues to run for 5 minutes, calculate how much water (drain) it produces in 5 minutes. Conditions ・ Intake air temperature 35 ℃ ・ Intake air humidity 80% ・ Compressor piston displacement volume (suction volume) 100m3 / h (hour) ・ Compression pressure 7kg / cm2 ・ Compressed air temperature 35 ℃ Calculation volume 100 m3 / h. The amount of water contained in 80% is 39.5 / m3 × 100 m3 / h × 0.8 = 3160 g / h (1). Converting compressed air of 7 kg / cm @ 2 and 35.degree. C. into atmospheric pressure dew point temperature is 0.degree. The amount of water vapor at 0 ° C. is 4.85 / m 2 from the saturated moist air table. Therefore, at 100 m3 / h, 4.85 g / m3.times.100 m3 / h = 485 g / h (2) Therefore, the amount of water (drain)
Since it is the formula (1)-(2), it becomes 3160 g / h-485 g / h = 2675 g / h 2675 g / h × 1/12 = 223 g / 5 min = 223 cc / 5 min. Thus, a lot of drain water is produced. This drain water is not entirely discharged together with the discharge air, but is partially separated as a drain in an air tank provided in the air compressor, but compressed air containing saturated steam is still discharged. The reason for this is that the function of the aroma generator described above is deteriorated.

Therefore, in the present invention, an aroma generator is provided in the discharge pipe of the air compressor, and the aroma generator is a chamber.
-The lower end is immersed in the liquid fragrance and the upper end is discharged.
An air-conditioning agent that has an fragrance outflow pipe that opens to a throttle provided in the road
Equipped with a Jector or granular fragrance in the chamber
In the fragrance device for an air compressor that is interposed in the discharge pipe so as to be passed through the compressed air, refrigerated air dryer during the discharge pipe is interposed, provided with the fragrance generator followed downstream of the air dryer The present invention proposes an aroma device in an air compressor device characterized by the above.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flow sheet of an embodiment of the present invention.
A refrigeration type air dryer 3 is interposed in the discharge pipe 2 of the air compressor 1, and aroma generators 4 and 4 ′ are arranged following the air dryer 3. Although the aroma generators 4 and 4'are arranged side by side in the figure, any one aroma generator 4 or 4'is provided. Of course, other equipment such as an aftercooler (not shown), a drain separator, and a dust filter, which are used for the compressed air discharge piping, are provided in the discharge piping 2 as required. The downstream side of the aroma generator 4 or 4'is directly opened to the space where the aroma is to be given, or compressed air is discharged to the atmosphere as exhaust gas from the pneumatic device via the pneumatic device.

In the air compressor 1, an air compressor 6 driven by an electric motor 5 sucks in air through an air suction pipe 7, boosts the pressure, stores it in an air tank 8, and stores compressed air in the air tank 8 through a discharge pipe 2 to a refrigerating air dryer. Feed to 3. The air dryer 3 is of a special refrigerating type, which cools and condenses saturated steam in compressed air and drains it by an attached drain wrap 9.

The fragrance generator 4 comprises a main body 11 and a fragrance containing chamber 13 which is hermetically attached below the main body 11 via an O-ring 12. The main body 11 has a compressed air passage. 14 is formed.
The compressed air discharge pipe 2 is provided on the upstream side 15 of the flow path 14.
The upstream side of the compressed air discharge pipe 2 is airtightly connected to the downstream side 16 of the flow path 14. Further, the flow passage 14 is formed with a throttle portion 17 at a substantially central portion thereof, and for guiding the compressed air passing through the compressed air discharge pipe 2 upstream of the throttle portion 17 into the fragrance storage chamber 13 around the throttle portion 17. A fragrance outflow pipe is formed with a guide hole 18, and the squeeze portion 17 is opened to the squeeze portion 17 and below the liquid level L of the liquid fragrance A stored in the fragrance storage chamber 13. 19 is provided.

Although various types of liquid fragrance agents A are considered, as described above, those called fragrances, those called so-called fragrances, and those called masking agents are used. Can be used. One example of the fragrance or fragrance is a natural fragrance (animal fragrances such as incense, scent, scent and scent of incense, roots of plants, branches, leaves, flowers, flower buds, peels, seeds, etc., and steam distillation. And a synthetic fragrance (e.g., a product obtained by a synthetic reaction such as oxidation or condensation from a pure synthetic raw material such as an extracted fragrance and a tar-based or petrochemical product) can be used.

Examples of the above-mentioned vegetable natural fragrance include citronella oil, camphor oil, lemon oil, lemongrass oil,
Orange oil, peppermint oil, eucalyptus oil, lavender oil, okocha oil, poad rose oil, bergamot oil, spearmint oil, lime oil, petitgrain oil, clove oil,
Examples include petipa oil and ylang-ylang oil.

Further, synthetic fragrances include, for example, benzene-based synthetic fragrances, artificial musk, tempen-based synthetic fragrances and the like.

Further, as the masking agent, there is a so-called representatively used wood vinegar solution to which the above-mentioned fragrance is added.

This operation will be described based on the above configuration. When the electric motor 5 is driven to drive the air compressor 6, air flows in from the end of the suction pipe 7, and the generated compressed air flows in the air tank 8. , Once stored there. The compressed air in the air tank 8 is discharged from the air discharge pipe 2 as the compressed air is used. The compressed air that has flowed out enters the refrigerating air dryer 3, is cooled in the air dryer 3, the water vapor in the compressed air is condensed, and is automatically discharged from the drain trap 9. Refrigeration air dryer 3
The compressed air that has been dehumidified and dried in (1) flows through the compressed air discharge pipe 2 and the flow path 14 on the downstream side.

In the above process, the compressed air is compressed by the throttle unit 1.
When passing through 7, since the flow passage cross-sectional area is narrowed, the pressure at the peripheral wall of the upper end portion of the fragrance outlet pipe 19 drops, while the compressed air is introduced into the fragrance containing chamber 13 from the guide hole 18. Since the agent A is supplied onto the liquid surface L, a pressure difference is generated between the pressure on the liquid surface L and the pressure at the upper end portion of the fragrance outflow pipe 19, and the throttle portion is passed through the fragrance outflow pipe 19. It is sucked out by 17. In this case, the fragrance A is sucked out in a vaporized state. That is, the fragrance A is vaporized by the ejector effect. As a result, the fragrance is mixed and imparted to the compressed air passing through the flow path 14, and the compressed air containing the fragrance component is obtained. There, it is released to the surrounding environment either directly or after being subjected to the intended work. Therefore, even if an unpleasant odor is generated in the air compressor itself, the pneumatic equipment itself, or both,
Since the odor is masked by the fragrance component, the person in the surrounding environment can be relieved from the discomfort caused by sniffing this unpleasant odor, and in some cases, can enjoy the rich fragrance.

Further, when the fragrance A in the fragrance-containing chamber 13 is consumed, a fragrance prepared in advance may be filled from an inlet (not shown), and the compressed air flow and the air may be applied thereto. To adjust the ratio of the fragrance components, the fragrance outflow pipe 19 may be provided with an orifice capable of adjusting the flow rate, which is not shown, and may be adjusted from the outside.

Although the guide hole 18 is provided in the present embodiment, the guide hole 18 may be omitted and a check valve-provided hole for introducing the atmosphere into the upper space of the fragrance-containing chamber 13 may be provided.

The fragrance generator 4'is an example in which a large number of solid fragrances are used as the fragrance agent A. That is, the liquid perfume and aroma substances related to the aroma generator 4 described above are combined into a solid mass using a solid binder as a binder, or the above-mentioned perfume is perfused to the natural fats and oils of the base material as a whole. Use a solid lump. However, in this case, the binder or the base material itself is selected so that it gradually evaporates and vaporizes under the pressure of compressed air.

Further, a primary side flow passage 20 is formed to introduce compressed air supplied from the upstream compressed air discharge pipe 2 into the main body 11 of the fragrance generator 4'first into the solid lump fragrance-containing chamber 13. Next, the secondary side flow passage 21 is formed so as to discharge the compressed air introduced into the fragrance storage chamber 13 to the downstream side compressed air discharge pipe 2. In addition, the fragrance outflow pipe 19 is connected to the secondary side flow passage 21 so that the end 22 is exposed to the inside of the packed layer of the solid lump fragrance A. Parts that are substantially the same as those of the other aroma generators 4 are given the same reference numerals.

In this way, the compressed air that has flowed in from the upstream compressed air discharge pipe 2 is introduced into the layer of the solid lump aromatic agent A through the primary flow path 20, and at this time, the solid lump aromatic agent A is introduced. To vaporize. Therefore, the aroma component is added to the compressed air introduced into the chamber 13,
The fragrant compressed air flows out of the downstream compressed air discharge pipe 2 through the fragrance outflow pipe 19 and the primary side flow passage 21.

Since the dry compressed air is supplied to the aroma generators 4 and 4'by the refrigeration type air dryer 3,
Or, the air released into the atmosphere through the pneumatic equipment is released from the pneumatic equipment to the surrounding environment even if an unpleasant odor is generated from the air compressor itself or the pneumatic equipment itself, or both of them. The odor in the exhaust gas is persistently acted on by the possibility that other people may detect an unpleasant odor, the consumption of the fragrance is reduced, and the fragrance of the fragrance used is kept good.
