Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deodorizer used for deodorizing air cleaners and refrigerators.

[Conventional technology]

In recent years, with the spread of air conditioning and heating, rooms have become more airtight, and indoor air pollution has become more noticeable. On the other hand, the effects of cigarette smoke, dead mites, pollen, etc. on the body have been medically clarified.
Demand for air purifiers is rapidly increasing. There is a need for a comprehensive air purifier that not only removes fine dust but also removes bad odors, and we offer a deodorizing filter made of urethane foam coated with activated carbon with adhesive and a paper filter that can capture fine particles as small as 0.01μ. Air purifiers etc. that combine these have been put into practical use and are commercially available.

Furthermore, as refrigerators become larger, long-term storage of large amounts of food has become commonplace, and the generation of complex odors has become a problem, creating a need for the development of deodorizers specifically for refrigerators.

One example that has already been put into practical use is one that uses an ozone generator to oxidize odor with ozone and turn it into odorless gas.

[Problem to be solved by the invention]

In conventional methods, the adsorption capacity of activated carbon has a small limit.
Immediately after use, the deodorizing ability is lost and the filter needs to be replaced frequently. Furthermore, with the oxidation method using ozone, there are concerns about safety because it is known that excess ozone does not have an adverse effect on the human body.

It is an object of the present invention to solve the problems of the prior art and to provide a practical deodorizer with good functionality.

[Means for Solving the Problems] The gist of the present invention to achieve this object is to use a deodorizing agent with remarkable differences in the environmental conditions for adsorption and desorption of malodorous gases, and to periodically adsorb and desorb malodorous gases. This is a deodorizer that continues to deodorize semi-permanently by controlling and discharging odor from the room to the outside of the room, like a one-way pump.

A deodorizer comprising a movable member having a plurality of compartments in which a deodorizer is loaded in a casing divided into an odor adsorption part and an odor release part, and independent ventilation means provided in each part in the casing. A plurality of compartments in which the deodorizer is loaded are configured by dividing a circular member radially, and the circular compartment member is rotatably provided, or a rectangular member is divided in parallel, and the rectangular The member is provided so as to be movable in parallel.

Some compartments loaded with deodorizers absorb odors as the air from the room you want to remove circulates through them. The "compartment room loaded with deodorizer", which is isolated from the other room whose odor is to be removed, circulates clean air from which odors escape from the deodorizer, or high-temperature air, water vapor, etc., which easily releases odors from the deodorizer. let

After a certain period of time, the layout of the compartments is changed, and a compartment loaded with a deodorizer that has regained its deodorizing ability is placed in the room where you want to remove odors. adsorbs. On the other hand, the compartment 1 loaded with the odor-absorbing deodorizer is isolated from the room from which the odor is to be removed, and is exposed to clean air, high-temperature air, water, etc. that makes it easier for the odor to escape from the deodorizer. By circulating it, the deodorizing performance is restored.

In the method of the present invention, the temperature of the room in which the odor is to be removed is 50''.
Under temperature conditions of C or lower and -5C or higher, gases that cause odors can be adsorbed and removed.

First, place the deodorizer in the room you want to remove the odor and let it absorb the odor. It is taken out of the room while keeping the room airtight, and the odor gas is released again, restoring the deodorizing ability to its initial level. After that, it is charged again into the room where the odor is to be removed while keeping the room airtight, and the gas that causes the odor is adsorbed.

Manually operated as a mechanism to deodorize, release, and regenerate at specified intervals.
It is conceivable that it would be automatic, but in any case, the regeneration means will start when the layout of the "compartment chamber loaded with deodorizer" is changed, and it will have a function to stop the regeneration process after a predetermined period of time. .

By repeating this process, deodorization can be achieved semi-permanently.

In order to continuously repeat this with a machine, it can be done efficiently by using a rotary type or a sliding type.

Next, the structure and operation of the deodorizer of the present invention will be explained with reference to FIG. FIG. 1 is an explanatory diagram of a deodorizer using a circular member.

For example, a porous body 2 having deodorizing performance, which is an iron porous body impregnated with tannic acid to form an iron tannate complex on the surface, is inserted into the gap of the rotary valve 1. One side is installed in a room where the odor is to be removed, and the other side is installed as a place from which the odor is removed, with a structure capable of keeping the room airtight with a partition wall 3.

In order to quickly absorb odors, the indoor air must absorb the porous material.
l! It is preferable to force the circulation with the fan 4 so that the water can be circulated. Then, turn the rotary valve so that the new porous material enters the room where you want to remove the odor, and the porous material that has absorbed the odor exits the room.

Outside the room, odor is removed, and odor-free, clean air is applied to the porous material to restore Hatsutomo's deodorizing performance. In this case as well, in order to speed up the recovery, it is necessary to
It is preferable to use a fan 7 to force the circulation so that it circulates through the air. Further, for example, if the temperature of the air passing through and circulating through the porous body is increased using the heater 5, the removal of odor will be promoted. However, if the iron tannate complex decomposes, the deodorizing ability will be impaired, so the temperature must be kept below 130°C.

When using steam for heating, conditions must be set to prevent water droplets from forming on the porous material. Otherwise, water molecules will adsorb to the iron tannate complex, reducing the deodorizing ability, or the iron, which is the matrix of the porous material, may adsorb to the iron tannate complex. Care must be taken as this may result in the promotion of oxidation and corrosion.

FIG. 2 is an explanatory diagram of a deodorizer using a rectangular member. 1st
As described in the figure, the deodorizer 2 removes the odor from the room and moves the position to release the odor.

Next, embodiments of the present invention will be described.

(Example 1) Using a rotary valve with the dimensions shown in Table 1, a deodorizing filter made of a barbed porous body with the properties shown in Table 2 was attached to the cavity of the rotary valve, and deodorization was performed under the operating conditions shown in Table 3. . The results are as shown in Table 4.
Even after repeating the test 0 times, no decrease in deodorizing ability was observed.

(Example 2) Using a rotary valve with the dimensions shown in Table 1, a deodorizing filter made of a barbed porous body with the properties shown in Table 5 was attached to the cavity of the rotary valve, and deodorization was performed under the operating conditions shown in Table 6. . The results are as shown in Table 7.
Even after repeating the test 0 times, no decrease in deodorizing ability was observed.

(Example 3) Using a rotary valve with the dimensions shown in Table 1, activated carbon having the properties shown in Table 8 was filled in the gap of the rotary valve with a nylon mesh having a mesh size of 1, and the carbon was attached as shown in Table 9. Deodorization was performed under operating conditions. As shown in Table 1O, the deodorizing ability did not deteriorate at all even after the deodorizing operation was repeated 10 times.
