Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for deodorizing a malodorous exhaust gas in a malodorous area such as a kitchen or a refuse processing plant to exhaust the malodorous gas.

[0002]

2. Description of the Related Art When the exhaust gas with the above-mentioned malodor is discharged to the outside as it is, it causes the pollutant to enter the room through an air-conditioning system, such as an outside air inlet, and pollute the room. When setting the position of the intake port for introducing fresh outside air into the mouth and the living room, it is necessary to select the optimum position in consideration of the influence of the air flow of intake and exhaust, but in reality, it depends on various construction plans. However, many problems remain due to various restrictions.

For this purpose, it is necessary to deodorize the malodorous exhaust gas, but as the conventional deodorizing means, an activated carbon filter is mainly used to remove the malodor and release it to the outdoors, or the malodorous exhaust gas is directly burned. Is adopted.

[0004]

When the activated carbon filter is used in the above-mentioned conventional means, there are problems that it is ineffective against high-concentration malodorous exhaust gas and has a short service life. In the case of the burning method, the deodorizing effect is sufficient, but the processing cost is high and there is an economical difficulty.

[0005]

The present invention eliminates the inconveniences of the conventional deodorizing means and makes the deodorizing effect more efficient. Therefore, there is a problem of the positioning of the openings of the odorous exhaust gas and the outside air intake of the building air conditioning system. A deodorizing exhaust means that can solve the problem of deodorizing via a deodorizing device that uses a deodorant in the middle of the exhaust pipe that sucks and discharges the malodorous exhaust in the malodorous area with a fan. It is characterized in that the air exhaust pipe is directly or indirectly connected to deodorize the malodorous exhaust gas by mixing the malodorous exhaust gas and the deodorant exhaust gas, and then discharges it to the outside through the exhaust port.

[0006]

The deodorizing exhaust treatment means for the malodorous exhaust according to the present invention,
As shown in the drawing of the embodiment, exhaust gas accompanied by a bad smell is sucked through the exhaust pipe line 2 by driving the fan 1 and is discharged to the outside from the exhaust port 3.

An exhaust side pipe line 5 of a deodorizing device 4 using a deodorant is connected to the middle of the exhaust pipe line 2 for the malodorous exhaust, and the deodorizing air containing the vaporized gas of the deodorizing agent that has passed through the deodorizing device 4 is exhausted as described above. After the malodorous exhaust gas is mixed with the malodorous exhaust gas in the exhaust pipe line 2 from the pipe 5 to remove the malodorous gas with the deodorizing air, the exhaust port 3
To be released outdoors.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the deodorizing exhaust means for offensive odor exhaust according to the present invention will be described with reference to FIG.

Exhaust pipe line 2 acting by driving fan 1
Consists of an intake-side conduit 2a of the fan 1 and an exhaust-side conduit 2b of the fan 2. The intake-side conduit 2a is opened in the foul-smelling area and the exhaust-side conduit 2b is opened outdoors by the exhaust port 3. Then, the malodor in the malodor generating region is discharged to the outside from the exhaust port 3 through the exhaust pipe line 2.

Reference numeral 4 is a deodorizing device using a deodorizing agent provided at an arbitrary position. An appropriate deodorizing agent is used, but a sap (phytoncide) -based one is preferable.

The air introduced into the deodorizing device 4 contains the vaporized gas of the deodorant so as to be taken out from the exhaust pipe 5, and the exhaust pipe 5 is connected to the middle of the exhaust pipe line 2 for the malodorous exhaust gas. The deodorizing air containing the vaporized gas of the deodorant that has passed through the exhaust pipe 5 is mixed with the malodorous exhaust gas that is exhausted through the exhaust pipe line 2.

In the illustrated embodiment, a chamber 6 is provided in the exhaust pipe 2 at an intermediate portion of the suction side pipe 2a, and the tip of the exhaust pipe 5 of the deodorizing device 4 is provided in the chamber 6 by a nozzle hole 5a. Opened, the negative pressure inside the chamber 6 is driven by the drive of the fan 1, and the bad odor exhaust is sucked from the suction side exhaust pipe line 2a, and the air is sucked and introduced into the deodorizing device 4, and the sucked air is vaporized as a deodorant. Deodorized air containing gas is discharged from the nozzle hole 5a into the chamber 6 through the exhaust pipe 5, and is mixed with the malodorous exhaust to deodorize the malodorous exhaust, and the exhaust side conduit 2b of the fan 1 is discharged.
It was discharged to the outside through the exhaust port 3.

That is, the deodorizing air that has passed through the deodorizing device 4 is mixed into the exhaust pipe line 2 by the suction force of the fan 1. In this case, the deodorizing device 4 does not need a fan for introducing air into the device 4 or exhausting it. However, when the suction force of the fan 1 is insufficient, the deodorizing device 4 may be provided with a fan for introducing and discharging air, and the deodorizing air may be forcibly sent to the intermediate portion of the exhaust pipe line 2.

When the deodorizing air that has passed through the deodorizing device 4 is mixed into the exhaust pipe line 2 using the suction force of the fan 1 as in the above embodiment, the suction side pipe line 2a in the exhaust pipe line 2 is used. However, when the deodorizing air is forcibly sent using a separate fan, the deodorizing air may be sent to the discharge side conduit 2b of the exhaust conduit 2 without being limited to the suction side conduit 2a.

Further, in the illustrated example, the exhaust pipe 5 is indirectly communicated with the exhaust pipe 2 by utilizing the inside of the chamber 6 provided in the middle portion of the exhaust pipe 2, but the exhaust pipe 5 is indirectly connected to the exhaust pipe 2. It is also possible to connect directly.

It is desirable that the exhaust pipe 5 for the deodorizing air is provided with a regulating valve 7 to adjust the amount of the vaporized gas mixed with the deodorizing agent with respect to the malodorous exhaust gas.

As described above, the exhaust gas from a place that produces a bad odor, such as a kitchen or a waste treatment plant, is deodorized by mixing with the deodorizing air containing the vaporized gas of the deodorizing agent that has passed through the deodorizing device 4, and is discharged from the exhaust port 3. In order to be discharged to the outside, an outside air intake 10 for air conditioning is provided in the vicinity of the exhaust port 3 as shown by a phantom line in FIG. 1, and the outside air taken in from this is subjected to a primary treatment by, for example, an air conditioner 11 to make a building. Even if the air is supplied to the inside, it does not have an adverse effect due to the exhaust gas discharged from the exhaust port 3, and therefore, the predisposition to the failure due to the exhaust relationship between the exhaust port and the outside air intake opening can be eliminated.

[0018]

According to the present invention, the malodorous exhaust is directly deodorized because the malodorous exhaust is discharged by mixing the malodorous exhaust with the deodorizing air containing the vaporized gas of the deodorant that has passed through the deodorizing device. Consumption of a large amount of deodorant as in the case of treatment with an agent can be omitted, and the use of a large-scale device can be omitted, and the malodorous exhaust gas can be deodorized by a simple means simply by mixing air containing a vaporized gas of the deodorant, Along with this, there is an effect that each opening can be easily positioned without requiring special consideration in the positional relationship between the exhaust port from the place where the bad smell is generated and the general outside air intake for air conditioning.
