Abstract

PURPOSE:To obtain a gas treatment apparatus having a simple structure and requiring no treatment of a waste deodorant solution, by mounting a dust- removing filter, a deodorant solution sprayer and a deodorant supported filter. CONSTITUTION:The gas containing a malodor sucked from a gas-introducing port 1 by rotating a fan 3 is passed through a dust-removing filter 4 to remove foreign matters in the gas and subsequently contacted with the deodorant solution being a dry distillation component of a camellia sprayed from a sprayer 5 in a wet treatment chamber 6 to remove the greater part of the malodorous component and sent upwardly through a filter 8. Next, the treated gas is passed through a deodorant supported filter 7 constituted by holding unglazed particles supporting a deodorant between net boidies to remove the remaining malodor. Because the mist-like deodorant solution carried from the wet treatment chamber 6 is adhered to the filter 7, the deodorant is always replenished. The deodorized gas receives sterilization treatment by the sterilizing lamp 13 provided to the ceiling of the apparatus and subsequently exhausted to the outside from an exhaust port 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas treatment device that efficiently removes bad odors from gas.

Conventional technology As a device to remove bad odors from the indoor atmosphere.

A dry treatment method is known in which an air conditioner is equipped with a filter using activated carbon, and the air conditioner is operated to remove foul odors from the gas while the gas containing the foul odor passes through the filter.

A wet treatment method is also known in which a deodorant solution is sprayed and brought into contact with a gas containing a bad odor, and the solution that has fallen to the bottom is circulated and sprayed again.

Problems to be Solved by the Invention Of the above conventional methods, the dry treatment method is widely used to remove bad odors from living rooms, etc. However, the bad odor removal effect is not necessarily sufficient, and the deodorization ability of the activated carbon filter is reduced. There is a problem in that the activated carbon filter must be inspected quickly and frequently.

On the other hand, the wet treatment method described above has an excellent odor removal effect, but because the deodorizing solution is recycled,
The installation of pumps and droplet prevention mechanisms required for circulation inevitably increases the size of the equipment, which increases equipment costs, generates noise, and makes it difficult to move the equipment.
There are problems such as the fact that it takes time and effort to dispose of deodorant waste liquid whose effectiveness has decreased.

In view of this situation, the present invention has been made with the object of providing an apparatus that is simple in structure and does not require treatment of deodorant waste liquid, although it partially employs a wet treatment method.

Means for Solving the Problems The gas processing device of the present invention is a device equipped with a gas inlet (1), a gas outlet (2), and a blower/exhaust fan (3),
A wet processing chamber (6) equipped with a dust filter (4) for removing foreign substances from the gas introduced through the inlet (1), and a sprayer (5) for spraying a deodorant solution onto the gas that has passed through the dust filter (4). ), and is characterized by being equipped with a deodorizer-carrying filter (7) that dry-processes the gas that has passed through the wet-processing chamber (6).By finding a device with such a specific configuration, the above I have achieved my goal.

The apparatus of the present invention will be explained in detail below with reference to Examples.

Embodiment FIG. 1 is a sectional explanatory view showing an example of the apparatus of the present invention, and FIG. 2 is a front view.

(9) is a housing constituting the outer wall of the device,
A gas inlet (1) is provided at the lower front surface, and a gas outlet (2) is provided at the upper front surface. (3) is a fan as an example of a blower/exhaust device, and is rotated by the drive of the motor (10).

(4) is a dust filter that removes foreign matter from the gas introduced through the inlet (1), and is installed obliquely at the bottom of the device.

(6) ° is a wet processing chamber located above the above-mentioned dust removal filter (4), and the chamber wall is equipped with a sprayer (5). (11) is a tank containing deodorant solution, (12)
is a pump for spraying the deodorant solution in the tank (11) from the sprayer (5). Dust removal filter (4
) is contacted with the deodorant solution sprayed from the atomizer (5) in this wet treatment chamber (6) and is treated. Although the deodorant solution may be sprayed continuously, it is usually sufficient to spray the deodorant solution intermittently.

(7) is a deodorizer-carrying filter that dry-processes the gas that has passed through the wet-processing chamber (6), and is installed above the wet-processing chamber (6) with a slight forward tilt. The number of deodorant-carrying filters (7) installed is arbitrary, and in this example, two are installed.

The deodorant in the deodorant solution sprayed from the sprayer (5) and the deodorant supported in the deodorant-carrying filter (7) include various plant essential oils having deodorizing effects, as well as glyoxal, Various deodorants can be used, such as lauryl methacrylate, zinc soap, aluminum chloride, boron compounds, amine compounds, and organic chlorine compounds. It is a dry distillate mainly from the leaves of plants, and its boiling point is 18 at 20 mmHg.
It is particularly preferable to use a temperature corresponding to 0 to 200°C (the boiling point will change if the degree of vacuum changes). Camellia plant carbonized distillate removes bad odor components themselves □
It not only traps and deodorizes the skin, but also has antibacterial properties.
Because it does. Such a carbonized fraction is obtained by directly carbonizing plants of the Camellia family under reduced pressure.

Among the Camellia family plants, the carbonized distillate from tea confectionery is particularly useful.

To make a deodorant solution, mix the above deodorant with water or alcohol.

;).

In addition, the above-mentioned deodorant-supported filter (7) has the following characteristics:
i; Porous materials such as granular materials and spongy materials
Various materials can be used if there is 1, but unglazed ceramics processed into granules are particularly preferred.
::・+t11゜ particles have a high ability to absorb moisture and bad odors.
This is because it maximizes the deodorizing ability of the 1:1 deodorizer (particularly the dry distillate fraction of plants of the Camellia family) and also has a small pressure drop.

The unglazed particles carrying the deodorant may be sandwiched between nets or the like to form a filter.

(8) is a filter that is provided as necessary, and this filter does not usually support a deodorizing agent. However, since the droplets or mist of the deodorant solution sprayed in the wet processing chamber (6) adhere to the deodorant solution, it essentially functions in the same way as the deodorant-carrying filter (7).

(13) is a germicidal light installed on the ceiling of the device. The installation of this germicidal lamp (13) can be omitted. .

Using this device, we deodorized atmospheres containing bad odors in animal dissection laboratories, animal breeding rooms, and hospital morgues where it is difficult to remove bad odors with normal deodorizing methods. In the 4-level evaluation, I was able to score 1 to 0 for those in stage 3, almost O for those in stage 2, and O for those in stage 1.

Stage 3: The foul odor is clearly strong Stage 2: The foul odor is present Stage 1: There is a slight foul odor Stage 0: Odorless operation In the device of the present invention, when the motor (IO) is driven, the fan (3) rotates, and the external gas turns into a gas. Inlet (
The gas passes through the inside of the device consisting of the gas outlet (2).
) is discharged to the outside again.

The foul-smelling gas sucked in from the gas inlet (1) first has foreign matter removed by the dust removal filter (4), and is sent to the wet processing chamber (6).

In the wet treatment chamber (6), the element containing the malodor comes into contact with the atomized deodorant solution sprayed from the sprayer (5), and most of the malodorous components are removed, and the element is passed through the filter (8). sent upwards.

In this case, the amount of sprayed deodorant solution is controlled so that it is carried upward by the gas and does not fall to the bottom and accumulate. Even if the deodorant solution is sprayed intermittently, the atomized deodorant solution remains in the wet treatment chamber, and the sprayed deodorant solution adheres to the surface of the filter (8). Since the surface of the filter (8) is in a wet state, a type of wet treatment is also performed on the surface of the filter (8).

The gas that has passed through the wet treatment chamber (6) then comes into contact with the deodorant carried therein while passing through the deodorant holding filter (7), thereby completely removing any remaining malodor.

This deodorant-carrying filter (7) has a wet processing chamber (6
), the mist deodorant solution that comes from
The deodorant will be constantly replenished and the filter (7)
The frequency of replacement is extremely low.

The gas that has passed through the deodorizer-carrying filter (7) is discharged to the outside again from the outlet (3) in a state where it no longer contains any bad odor, but the gas is discharged outside from the outlet (3) again when necessary.
13) enables sterilization treatment.

Effects of the Invention The device of the present invention has both a wet treatment method with a high deodorizing effect and a simple dry treatment method, so it has an excellent odor removal effect even if the malodor has a complex composition. . In particular, the effect of removing bad odors when using the dry distillate of plants of the Camellia family as a deodorant is extremely excellent.

Furthermore, although it is equipped with a reprocessing method, the device is compact and has advantages in terms of area occupied, device cost, and mobility.

Even though it incorporates a wet treatment method, the deodorant solution does not accumulate at the bottom of the device, so it is extremely advantageous in that it does not require the installation of deodorant waste liquid processing equipment or the effort of waste liquid treatment. It is.

In addition, the sprayed deodorant solution is captured by the deodorant-carrying filter and exerts its deodorizing effect here as well, so not only does the deodorant not go to waste, but the deodorant-carrying filter also has a deodorizing effect. Since the deodorant is automatically replenished, the life of the deodorant-carrying filter is significantly extended, and the frequency of its replacement is significantly reduced.

Since the device of the present invention has various excellent points as described above, it is highly practical.
