Abstract

PURPOSE:To obtain a deodorant, which is low-priced, able to be regenerated with a mild heat source and moreover has an adsorbing power for sulfur dioxide, by making A-type zeolite contain oxides of copper and manganese. CONSTITUTION:In regard to a deodorant suitable to be set at various places such as a home air cleaner, toilet, bath room, etc., A-type zeolite, which has a strong deodorizing power, is made to contain oxides of copper and manganese, which are black and reactive with odor components, at a ratio of (the former):(the latter)=100:(5-50) as a main body of the deodorant. A used deodorant is easily regenerated after desorbing adsorbed offensive odor components easily by being heated up to about 100 deg.C with solar heat, infrared ray lamp, etc., because this deodorant has high absorptivity for heat ray. Moreover, this deodorant has a secondary action of oxidizing CO to CO2, too.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to various places such as household air cleaners, toilets,
This article relates to deodorizing agents suitable for installation in bathrooms, closets, hospitals, nursing homes, garbage bins, pet farms, garbage collection sites at municipal garbage incinerators, human waste disposal sites, etc.

[Conventional technology]

Activated carbon and other adsorbents conventionally used as deodorizing agents are mainly disposable, and there are few that can be recycled and reused.

[Problem that the invention seeks to solve]

In view of the above-mentioned state of the art, the present invention aims to provide a deodorizing agent that can be easily recycled and reused. This is a deodorizing agent containing gold.

In the present invention, type A zeolite, which has a large deodorizing ability, is used as a deodorizing agent, and it contains copper and/or manganese oxides that are reactive with odor components and have a black color. . ^ type, the blending ratio of zeolite and steel and/or manganese oxide is the former; the latter = 100:5 to 50
It is.

[Effect]

■ Affi zeolite, which has a large deodorizing ability, is used as the main body of the deodorizer, so it has a high deodorizing effect.

■ Methyl mercaptan, SO□, etc., which are difficult to deodorize, react with copper and/or manganese oxides, so they have a high deodorizing effect.

■ Since it contains black steel and manganese oxides, the deodorizing agent absorbs a lot of heat rays, so it is heated to about 100℃ using solar heat or an infrared lamp, which easily removes the adsorbed malodorous components. It can be easily removed and reused.

■ In addition to acting as a deodorizer, co ftco2
It also has the side effect of oxidizing to

〔Example〕

4A type zeolite was used as a deodorizer. Trimethylamine 10 P, I) as an odor source! 1. When the deodorizing performance was evaluated using diluted air, 1. Om mol
/ I (5■ cylindrical) adsorption capacity reached the peak of this 4A type zeolite, and above this, breakthrough occurred.

(&) in Fig. 1 shows the temperature rise when the trimethylamine deodorizer was installed at a location directly below a 100W infrared lamp. The adsorption amount of trimethylamine after regeneration treatment under these conditions is Q,
It was 2 mmol/11.

Add twice the molar amount of ammonia to the sulfate radicals in a 20% by weight aqueous solution of manganese sulfate to precipitate manganese hydroxide,
Water was added to this manganese hydroxide solution and oxidized by supplying oxygen at 0° C. to obtain black manganese oxide (highly active manganese).

This precipitate was separated, washed with water, dried at 105°C,
It was sprinkled on the surface of muzeolite (5 intestinal casts).

This product was used as a deodorizer in the same manner as above, and then heated with an infrared lamp. In the state 'eiI diagram (b
Shown in l.

The adsorption amount of trimethylamine in this manganese-treated deodorizer is 1.01@1101/9, but when it is regenerated, it is possible to regenerate 100'A.

Next, a black oxidized steel was obtained by spraying the 103 nitric acid steel aqueous solution into heated air at 350°C. This oxidized steel 105At-4
When sprinkled on the surface of A zeolite deodorizer and heated with an infrared lamp, the temperature rise pattern was exactly the same as that shown in Figure 1 (bl), and the adsorption amount of trimethylamine was 1.0*so
b/9 and the playback rate was 100S, which was rare.

A similar effect was observed when a 50% mixture of these oxidized steels and manganese oxide was sprinkled on the deodorizer at 10%.

In addition, if it is regenerated by irradiating it with the summer sun for 2 hours after the sun goes down,
A regeneration rate of 90% was observed for the above example, compared to a regeneration rate of 15% for the example with only 4A zeolite. Also,
Although the deodorizing agent in the example of 4A zeolite does not have the ability to adsorb sulfur dioxide, in any case of the examples of the present invention, the deodorizing agent is 0.2 m
Adsorption ability of mol/I deodorizer was observed.

〔Effect of the invention〕

A deodorizing agent is provided that can be easily regenerated using an inexpensive and mild heating source such as solar heat, and is also provided as a deodorizing agent that has the ability to adsorb sulfur dioxide in combustion exhaust gas such as kerosene fuel.
