DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used for a drain of an air conditioner, and is intended to simply and reliably neutralize condensed water generated when compressing acidified air. The present invention relates to a neutralization device using oyster shells.

[0002]

2. Description of the Related Art In recent years, air that has been acidified due to harmful exhaust gas from factories, exhaust gas from automobiles, and the like has been highlighted as a variety of pollution problems.

[0003] In particular, condensed water generated when such acidified air is compressed may exhibit an acidity of at most PH4 to 4.5, and equipment utilizing the compressed air or compressed to that point. This is a major factor that corrodes pipes that send air, etc., and has a serious problem of causing secondary pollution because the condensed water generated there is acidic water itself.

In view of the above, there has been a method for preventing rust of an air compression device which has been proposed by the present applicant in Japanese Patent Application Laid-Open No. 1-220002.

In this rust prevention method, neutralization is performed by alkaline ionized water formed by electrolyzing condensed water, thereby preventing various types of equipment behind.

[0006]

However, such neutralization with only alkaline ionized water by electrolysis of condensed water inevitably involves measuring the acidity at the location where the alkaline ionized water is generated. At present, no treatment was taken for the acidity of the place before that, and at this stage corrosion could not be prevented at that stage.

In view of the above-mentioned problems, the present invention neutralizes acidified water contained in compressed air immediately after the compressed air is formed, and neutralizes condensed water generated. It has been created with the task of easily and reliably achieving the conversion.

[0008]

According to the present invention, there is provided a neutralization apparatus for neutralizing acidic moisture contained in compressed air of an air conditioner, wherein a neutralization chamber in which oyster shells are accumulated is formed.
The above-mentioned problem is solved by piping the compressed air before dehumidification through the neutralization chamber.

In a neutralization device for neutralizing acidic moisture contained in compressed air of an air-conditioner drain, a neutralization chamber in which oyster shells are accumulated is formed, and the neutralization chamber before dehumidification is formed in the neutralization chamber. The above-mentioned problem has been solved by forming a pipe for passing compressed air, and forming the condensed water removed by the dehumidifier disposed behind the neutralization chamber back to the neutralization chamber again. Is the solution.

[0010]

According to the present invention, there is provided a neutralization apparatus for neutralizing acidic moisture contained in compressed air of an air-drain, wherein the oyster shells accumulated in the neutralization chamber are neutralized. The shell is calcareous in its components. Therefore, when the compressed air before dehumidification is passed through, the calcareous material is alkaline and the oyster shell has a large contact area, so that the acidic moisture contained in the compressed air is neutralized.

In the neutralization device for neutralizing the acidic moisture contained in the compressed air of the air-conditioner drain, a neutralization chamber in which oyster shells are accumulated is formed. Pipes to allow the compressed air to pass through, and the condensed water removed by the dehumidifying device arranged behind the neutralization chamber is formed to return to the neutralization chamber again to pass therethrough. Neutralization at the stage of passing compressed air, and even if the neutralization is still insufficient, the condensed water removed by the dehumidifying device is returned to the neutralization chamber again and passed, so that it is neutralized reliably It is intended.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

That is, reference numeral 1 shown in FIG. 1 designates a neutralization tank 1 as a neutralization chamber.
As shown in FIG. 1, a shell accumulation portion 2 in which oyster shells are accumulated is arranged in an intermediate portion, and a compressed air inlet 5 is provided at a lower portion of the neutralization tank 1 with the shell accumulation portion 2 therebetween, and an upper portion is provided. Is provided with a compressed air outlet 6 so that the compressed air entering from the compressed air inlet 5 passes through the compressed air outlet 6. Here, the type of shellfish in the shell accumulation unit 2 is optimally oyster. In this case, it is better that the shell of the oyster shell is crushed to an appropriate size, thereby reliably neutralizing the acidic condensed water W.

Actually, condensed water W of PH 4 to 4.5 is supplied to PH
It can be neutralized to about 7 to 7.5.

Reference numeral 3 in the figure is a drain pipe, and reference numeral 4
Is a drain valve.

As a specific embodiment, as shown in FIG. 2, the compressed air entering from the compressed air inlet 5 passes through the neutralization tank 1 and is dehumidified through the compressed air outlet 6 and the compressed air inlet 15. The circuit is formed so as to be fed into the device 11 and then dehumidified and sent out from the compressed air outlet 16.

Here, the dehumidifying device 11 has a cooling coil 12 disposed substantially at the center thereof, and the compressed air entering through a compressed air inlet 15 disposed below the dehumidifying device 11 with the cooling coil 12 interposed therebetween is cooled by a cooling coil. It is formed so as to be cooled by passing around the periphery 12 and obtain condensed water W. A demister 19 is disposed above the cooling coil 12 to remove dust and other mist from the compressed air, and then sent out from the compressed air outlet 16. Here, the cooling coil 12 enters the cooling water inlet 17 and enters the cooling water outlet 18.
It is formed so as to be cooled by cooling water discharged.

Then, the condensed water W accumulated in the bottom of the dehumidifier 11 is formed so as to be sprayed from the upper part of the shell collecting part 2 of the neutralization tank 1 by the power of the pump 20. Even if the condensed water W remaining in the bottom of the inside 11 still shows acidity, water is again sprayed on the shell accumulation part 2 of the neutralization tank 1 to achieve neutralization again.

Reference numeral 13 in the figure denotes a drain pipe, 14
Is a drain valve, and it goes without saying that the present invention is not limited to the above-described embodiment.

[0020]

According to the present invention thus formed, in a neutralization device for neutralizing acidic water contained in compressed air of an air conditioner, a neutralization chamber in which oyster shells are accumulated is formed. However, by piping the compressed air before dehumidification through this neutralization chamber, the shells of the oyster shells accumulated in the neutralization chamber are calcareous, so the compressed air before dehumidification is added here. When passed, the calcareous material is alkaline, and the oyster shell has a large contact area, so that the acidic moisture contained in the compressed air can be neutralized.

At this time, a pipe is provided to allow the compressed air before dehumidification to pass through the neutralization chamber, and the condensed water W removed by the dehumidifier 11 disposed behind the neutralization chamber is again discharged into the neutralization chamber. The condensed water W removed by the dehumidifier 11 after being neutralized at the stage of passing compressed air before dehumidification by being formed so as to be passed back to the soaking chamber, even if the neutralization is still insufficient. Is returned to the neutralization chamber and passed therethrough so that neutralization can be surely achieved.

As described above, according to the present invention, the acidified water contained therein can be neutralized immediately after the compressed air is formed, and the generated condensed water is neutralized. The oyster shells are usually discarded, but the oyster shells can be used, so that it is very efficient and therefore inexpensive acidified water neutralizer. And various other excellent effects such as being able to be provided.
