Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of deodorizing a malodorous exhaust gas in a malodorous area, such as a kitchen or a waste treatment 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 living room through an air conditioning system, for example, the 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 it is actually different in the construction plan. However, many problems remain due to various restrictions.

For this purpose, it is necessary to deodorize the above-mentioned 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 directly burn the malodorous exhaust gas. Is adopted.

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

Exhaust pipe line 2 acting by driving a 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 opens to the malodor producing area and the exhaust-side conduit 2b opens to the outside through the exhaust port 3. Then, the malodor in the malodor generating region is discharged to the outside from the exhaust port 3 via the exhaust pipe 2.

Reference numeral 4 denotes 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 deodorizing agent so as to be taken out from the exhaust pipe 5, and the exhaust pipe 5 is provided at least in the exhaust pipe line 2 for the malodorous exhaust gas.
By communicating with the upstream side of one bent portion and the upstream side of the fan 1 mounting position provided in the exhaust pipe line 2, the deodorizing air containing the vaporized gas of the deodorizing agent via the exhaust pipe 5, The malodorous gas exhausted through the exhaust pipe line 2 is mixed.

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. Open and open a negative pressure in the chamber 6 by driving the fan 1 to suck off the bad odor exhaust from the suction side exhaust pipe 2a, suck air into the deodorizing device 4, and further vaporize the sucked air as a deodorant. Deodorized air containing gas is blown out into the chamber 6 from the nozzle hole 5a 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 from the exhaust port 3 through the.

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, in the deodorizing device 4, a fan for introducing air into the device 4 and exhausting it is omitted. However, if 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 by 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.

Furthermore, 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 deodorizing air be provided with a regulating valve 7 to adjust the amount of the vaporized gas of the deodorizing agent mixed with 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. Since the air is 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, there is no adverse effect due to the exhaust gas discharged from the exhaust port 3, and therefore, the predisposition to a 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 deodorized and exhausted by mixing the malodorous exhaust with the deodorizing air containing the vaporized gas of the deodorant that has passed through the deodorizing device. massive consumption of deodorant further be obtained by omitting the use of large-scale equipment, the flow of the exhaust conduit by the exhaust pipe is bent as in the case of treatment by agent
Due to the turbulence of the air and the stirring action of the fan, malodorous air and deodorized air are mixed and agitated while flowing through the exhaust pipe line, deodorized and discharged from the exhaust port. It is not necessary, and since the exhaust gas is deodorized and released from the exhaust port, no special consideration is required for the layout relationship between the exhaust port of the exhaust from the place where the bad smell is generated and the general outside air intake port for air. This has an effect that each opening can be easily positioned.
