Description

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

Conventional technology As a device for removing bad odors from 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.

Japanese Utility Model Publication No. 111653/1983 discloses a horizontal deodorization and toxic gas removal device that combines wet and dry processing.

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., but the bad odor removal effect is not always sufficient, and the deodorizing ability of the activated carbon filter is reduced. There is a problem in that the activated carbon filter must be replaced 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 used in circulation, the equipment becomes larger due to the installation of a pump and a droplet prevention mechanism required for circulation. This inevitably increases the cost of the device, generates noise, makes it difficult to move the device, and requires time and effort to dispose of deodorizing waste liquid with reduced effectiveness.

The device that combines wet treatment and dry treatment described in Japanese Utility Model Application Publication No. 111653/1983 also circulates water or reaction liquid, so it requires pumps and piping required for circulation, and storage of the liquid that has fallen. The equipment is inevitably complicated in terms of tanks, etc., and the equipment is horizontal and the gas flow is horizontal, so although it is suitable for liquid circulation, it is not necessarily advantageous in terms of wet processing efficiency. Furthermore, there is a disadvantage that the occupied area becomes large.

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 vertical device equipped with a gas inlet 1 at the bottom of the device, a gas outlet 2 at the top of the device, and a blower/exhaust fan 3 at an appropriate location of the device. At the bottom of the device near the introduction port 1, a dust removal filter 4 is provided for removing foreign substances from the gas introduced from the introduction port 1. Above the dust removal filter 4, the dust removal filter 4 is installed. A wet processing chamber 6 equipped with a sprayer 5 for spraying a deodorizing solution containing a dry distillate of the leaves of a plant of the Camellia family into the passing gas is provided, and the deodorant solution is supplied to the wet processing chamber 6. The structure is configured so that the gas is carried upwardly by the gas, and above the wet processing chamber 6, in order to dry-process the gas that has passed through the wet processing chamber 6, carbonized leaves of Camellia plant leaves are added to the unglazed particles. A deodorant-carrying filter 7 having a structure in which a deodorizing agent is carried is installed, and by finding a device with such a specific structure, the above object has been achieved.

For convenience of explanation, the specific structure will first be explained using examples, then the operation will be described, and finally the effects of the invention will be described.

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

Reference numeral 9 denotes a housing constituting the outer wall of the apparatus, and has a gas inlet 1 at the lower front and a gas outlet 2 at the upper front. A fan 3 is an example of a blower/exhaust fan, and is rotated by the motor 10 .

Reference numeral 4 denotes a dust removal filter for removing foreign substances from the gas introduced through the inlet 1, and is installed obliquely at the bottom of the apparatus.

6 is a wet processing chamber located above the above-mentioned dust removal filter 4, and a sprayer 5 is provided on the chamber wall. 11 is a tank containing a deodorizing solution containing a dry distillate of leaves of plants of the Camellia family; 12 is the tank 11;
This is a pump for spraying the deodorant solution inside from the sprayer 5. In this case, conditions are set so that the supply of the deodorant solution to the wet processing chamber 6 is limited to a range that is carried upward by the gas. Spraying of the deodorant solution from the sprayer 5 may be carried out continuously, but it is usually sufficient to spray the deodorant solution intermittently.

The gas that has passed through the dust removal filter 4 comes into contact with the deodorant solution sprayed from the sprayer 5 in this wet processing chamber 6 and is treated.

Reference numeral 7 denotes a deodorizing agent-carrying filter for dry-processing the gas that has passed through the wet-processing chamber 6, and is installed above the wet-processing chamber 6 so as to be inclined slightly forward. This deodorant-carrying filter 7 has a structure in which unglazed particles carry the carbonized distillate of leaves of plants of the Camellia family. The number of deodorant-carrying filters 7 to be installed is arbitrary, and in this example two filters are provided.

The above-mentioned carbonized distillate from the leaves of Camellia plants refers to the carbonized distillate from the leaves of plants of the Camellia family, such as tea, sasanqua, camellia, sakaki, and motsukoku, whose boiling point corresponds to 180 to 200°C at 20 mmHg. It is particularly preferred to use (the boiling point changes depending on the degree of vacuum). The carbonized distillate of leaves of plants of the Camellia family directly captures and deodorizes the malodorous components themselves, and also has an antibacterial effect. Such a carbonized fraction is obtained by directly carbonizing the leaves of a plant of the Camellia family under reduced pressure. Among plants of the Camellia family, the carbonized distillate from tea leaves is particularly useful.

A solution of the carbonized distillate of leaves of a plant of the Camellia family is prepared by dissolving the carbonized distillate of leaves of a plant of the Camellia family mentioned above in water, alcohol, or the like.

As described above, in the deodorant-carrying filter 7, unglazed particles obtained by processing unglazed clay into granules are used as a carrier for supporting the carbonized distillate of leaves of plants of the Camellia family. Unglazed particles have a high ability to absorb water and bad odors, so they maximize the deodorizing ability of the carbonized distillate of leaves of plants of the Camellia family, and also have low pressure loss. Unglazed particles carrying the carbonized fraction of leaves of plants of the Camellia family may be sandwiched between nets or the like to form a filter.

8 is a filter provided as necessary,
This filter usually does not carry the carbonized distillate of leaves of plants of the Camellia family. However, the wet processing chamber 6
Since the droplets or mist of the deodorant solution sprayed in the deodorant solution adhere to the deodorant solution, it has substantially the same effect as the deodorant-carrying filter 7.

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

Using this device, we have 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. With the four-stage judgment,
Those in stage 3 are 1 to 0, and those in stage 2 are approximately 0.
Finally, I was able to reduce the stage 1 level to 0.

Stage 3: The foul odor is obviously strong. Stage 2: There is a foul odor. Stage 1: There is a slight foul odor. Stage 0: Odorless action. When the motor 10 is driven in the device of the present invention, the fan 3 rotates and external gas is sucked through the gas inlet 1. The gas passes through the inside of the device upward, and is discharged to the outside from the gas exhaust port 2 again.

The foul-smelling gas sucked through the gas inlet 1 is first cleaned of foreign matter by the dust removal filter 4 and sent to the wet processing chamber 6 .

In the wet treatment chamber 6, the gas containing the malodor comes into contact with the atomized deodorant solution sprayed from the sprayer 5, and the malodorous components are removed by the dry distillate of the leaves of the Camellia family plant contained in the deodorant solution. Most of it is removed and sent upward through a filter 8.

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 6, and the surface of the filter 8 is covered with carbonized leaves of the camellia plant that have been sprayed. The surface of the filter 8 is also subjected to a type of wet treatment, since the deodorant solution containing the components adheres thereto and is in a wet state.

The gas that has passed through the wet treatment chamber 6 then comes into contact with the carbonized distillate of the leaves of the Camellia family plant carried there while passing through the deodorizer carrying filter 7 above, and the remaining bad odor is completely removed. removed.

Since the deodorizing agent carrying filter 7 is coated with the atomized deodorizing solution carried from the wet treatment chamber 6, the dry distillate content of the leaves of the camellia family plants is constantly replenished and deodorizing. The frequency of replacing the agent-carrying filter 7 is extremely low.

The gas that has passed through the deodorizer-carrying filter 7 is discharged to the outside from the outlet 3 again in a state where it no longer contains any bad odor, but it is sterilized by a germicidal lamp 13 installed as necessary on the ceiling of the device. be able to.

Effects of the Invention In the apparatus of the present invention, the wet treatment chamber 6 on the lower side of the vertical apparatus is efficiently deodorized by the wet treatment method, and the deodorizer carrying filter 7 on the upper side
The dry method is used to eliminate odors.

In addition, as the deodorizing solution supplied to the wet processing chamber 6 and the deodorizing agent supported on the deodorant-carrying filter 7, a dry distillate of the leaves of a plant of the Camellia family is used. Since unglazed particles are used as a carrier for the odor agent, the deodorizing effect is perfect even if the odor has a complex composition, such as those found in animal dissection laboratories, animal breeding rooms, and hospital morgues. .

Moreover, the deodorizing solution sprayed into the wet processing chamber 6 is captured by the deodorant-carrying filter 7 and exerts its deodorizing effect there as well. Agent-carrying filter 7
As a result, the life of the deodorant-carrying filter 7 is significantly extended, and the frequency of its replacement is significantly reduced.

In addition, 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 treatment equipment or the effort of waste liquid treatment. be.

And since it has a vertical structure as mentioned above,
Despite having both a wet type and a dry type, the device is compact and has advantages in terms of area occupied, device cost, and mobility.

In this way, in the present invention, since the wet processing chamber 6 on the lower side of the vertical device and the deodorizing agent-carrying filter 7 on the upper side are linked together, the device is as simple as possible. Despite this, the maximum deodorizing effect is achieved.
