Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing apparatus having a powerful deodorizing and harmful gas decomposing function corresponding to a high concentration market.

[0002]

2. Description of the Related Art For example, in stores and hospitals such as barbers and beauty salons, due to the contents of their work, they are placed in indoor air.
It is highly likely that it contains bad odors (eg, ammonia, acetaldehyde, trimethylamine, methyl mercaptan, etc.) or harmful gas components (eg, carbon monoxide, formaldehyde, etc.) that adversely affect humans. Therefore, there is a particularly strong demand for removing odor components and harmful gas components from indoor air, and various technologies have been proposed to meet such demands.

For example, conventionally, in a commercial air conditioner, as a method of removing an odor component or a harmful gas component, an adsorbent such as activated carbon or zeolite is combined with a filter, and an odor component or a harmful gas is removed by the adsorbent. It was common to adopt a method of adsorption removal. However, according to such a conventional deodorizing method, although odor components and harmful gases and the like in the indoor air are removed by adsorption, the adsorbed odor components and harmful gases and the like are only retained, and no processing is performed. If the amount of adsorption is saturated, no further adsorption and removal can be performed, and as a result, the service life of the deodorizing section is short and needs to be replaced, which in turn increases the running cost of the air conditioner. was there.

One of the most effective methods for avoiding such a problem is to regenerate the function of the adsorbent by oxidatively decomposing and removing odor components, harmful gases and the like adsorbed and collected by the adsorbent with an appropriate catalyst. Has been noticed because it is a clean process and has a long service life, and various techniques for realizing it have been proposed (for example, see Japanese Patent Application Laid-Open No. 5-290763).

It is intended to remove the odor components and harmful gases etc. in the air by adsorbing and removing the adsorbed odor components and harmful gases, etc. by using a catalyst as appropriate to regenerate the function of the heater. The odor components and harmful gases are limited to those contained in the air that touches the surface of the deodorizing heater. Therefore, the amount of the odor components and harmful gases to be adsorbed and removed (that is, the amount of deodorization) is small.
Therefore, its effect is small in purifying indoor air having a relatively large volume, and there is no choice but to leave practically unsatisfactory results.

In the above-mentioned known example, an adsorbing structure for adsorbing odorous components and harmful gases and the like and a catalyst for oxidizing and decomposing odorous components and harmful gases generated by desorption of the adsorbing structure are provided in the air conditioner. Since the structure is provided with the structural body, the structure of the apparatus and restrictions on the upper limit temperature at the time of activating the catalyst become problems, and problems such as insufficient capacity and cost increase remain.

The present invention has been made in view of the above points, and has an adsorbing section for adsorbing odor components and harmful gases, and a catalyst section for oxidizing and decomposing odor components and harmful gases released from the adsorbing section. The purpose of the present invention is to make it possible to adsorb and remove a large amount of odor components and harmful gases, and to decompose them by adopting a configuration in which is separated.

At least one metal of Mn, Rh, Fe or Co or a metal oxide composed of these metals is supported. Each of these catalysts has a novel structure according to the present invention, and exhibits a higher level of decomposition performance than a conventional catalyst.

In the deodorizing device configured as described above, the following operational effects can be obtained.

(I) During deodorizing operation At this time, the damper 15 is closed and the intake fan 16
Is stopped, and the adsorbent heating means 7 in the adsorption mechanism X is stopped.
The catalyst heating means 12 in the decomposition mechanism Y is in a non-energized state.

When the fan 4 is driven to rotate by the fan motor 9, as shown in FIG.
It is sucked into the machine from the contaminated air inlet 2 and firstly the decomposition mechanism X
, The odor component or the harmful gas component contained in the contaminated air Wa is adsorbed and removed by the adsorbent in the adsorbent structure 6 constituting the adsorbing mechanism X, and becomes the clean air Wb. The clean air Wb is sent to the heat exchanger 8 and exchanges heat with the refrigerant in the heat exchanger 8 to be heated or cooled, and is blown into the room from the clean air outlet 3.

In this case, the adsorbing mechanism X is constituted by a cylindrical adsorbing structure 6, and the entire amount of contaminated air Wa in the room flows through the adsorbing structure 6, so that the total amount of passing air Is the object of removal of odor components and harmful gases and the like in the adsorption structure 6, for example, only the odor components and harmful gases contained in the air that touches the surface of the plate-shaped deodorization heater as in the related art are targeted for adsorption and removal. The amount of odor components, harmful gases, and the like to be adsorbed and removed is much larger than in the case of this configuration, and the deodorizing ability of the adsorption mechanism X is drastically improved.

The desorbed contaminated air Wc containing odor components and harmful gases desorbed from the adsorbent is led to the exhaust passage 10 to form the catalyst structure 11 activated by heating by the catalyst heating means 12. Oxidative decomposition by the catalyst
After being deodorized and made harmless, it becomes clean air Wd and is discharged from the outlet 10b of the exhaust passage 10 to the outside of the room.
