Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant cartridge for a train storage type toilet which can be conveniently used.

[0002]

2. Description of the Related Art Conventionally, there are no filters or cartridges for suppressing the bad odors of ammonia, hydrogen sulfide, etc. generated from a train storage type toilet, and generally, the deodorants for processing the bad odors are porous carbon such as activated carbon or zeolite. Those that use high-quality inorganic components are the mainstream. In these cases, although the adsorption power is certainly high, since it is not basically a reaction such as neutralization or decomposition, and because it is not used in a sufficient amount, sufficient absorption is not performed, To
There is a drawback that a large amount of offensive odor such as ammonia will be emitted outside.

Further, although a liquid deodorant is sometimes used, it is difficult to hold the malodor generated from a train storage type toilet and it is difficult to use it. In the conventional method of using the liquid deodorant, the supply amount of the deodorant is insufficient, and therefore, even if the deodorant itself is highly active, the deodorant effect may not be exhibited. In particular, it has been difficult to exert and realize the deodorizing effect over a long period of time. That is, it is considered that it is difficult for the liquid deodorant to continuously work because the liquid of the active ingredient flows out or the active ingredient evaporates.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and provides a system which is convenient for use and which sufficiently removes and deodorizes malodorous gas in exhaust from a train toilet. As a result of intensive research, as a countermeasure against these problems, silica gel or activated carbon or zelite impregnated with an aldehyde compound solution and silica gel, activated carbon or zeolite impregnated with an aqueous solution of organic acid were used as toilets. It is possible to prevent and eliminate the generation of bad odors for a long time, and to continue the deodorizing effect for a long time.
Another object of the present invention is to provide a practical deodorant cartridge for a train storage toilet that is easy to handle. Another object of the present invention is to provide a deodorant cartridge for a train-reservoir type toilet that does not scatter, does not diffuse into gas, and has a stable deodorizing effect for a long period of time.

[0005]

The present invention has been made to solve the above-mentioned technical problems, and silica gel,
Particles of one or more substances selected from activated carbon and zeolite are mixed and filled with one impregnated with an aldehyde compound solution and one impregnated with an organic acid aqueous solution. A train-reservoir type characterized by attaching a filter container cartridge having a filter plate having holes to the tip of an exhaust pipe of a train-reservoir type toilet to allow exhaust containing malodorous gas to pass therethrough and deodorize malodorous gas. To provide a deodorant cartridge for a toilet.

[0006]

According to the deodorizing cartridge for a train storage type toilet of the present invention, particles of one or more substances selected from silica gel, activated carbon and zeolite are impregnated with an aldehyde compound solution and an organic acid aqueous solution. A filter container in which the impregnated one is mixed and filled is attached to the tip of an exhaust pipe of a train-reservoir type toilet so that the malodorous gas-containing exhaust gas is passed therethrough to deodorize the malodorous gas.

That is, since the silica gel, activated carbon and zeolite impregnated with the aldehyde compound solution and the organic acid aqueous solution used in the deodorizing cartridge for electric train storage type toilet of the present invention originally have a large physical adsorption amount, It can be impregnated with a large amount of liquid, and can remove a bad odor by a reaction such as neutralization. However, all of these materials are in the shape of powder or granules, which makes them difficult to handle. In the present invention, it is
This is solved by using a container. Furthermore,
Since the particles have a spherical shape or a shape close to a spherical shape, they can be easily filled in the filter-container and handled easily. The size of those particles is 0.5 mm to 2 m
m. This size determines the deodorizing effect because the surface area of the sphere is determined.

Further, silica gel, activated carbon and zeolite used in the deodorizing cartridge for electric train storage type toilet of the present invention have a large physical adsorption amount, and in particular, the finer the particles, the greater the adsorption amount. That is, the impregnated amount of the aldehyde compound solution or the organic acid aqueous solution also becomes large. Therefore, it has the effect of adsorbing and absorbing the malodorous components in the malodorous gas discharged from the train storage toilet, that is, the malodorous substances ammonia, hydrogen sulfide, and mercaptans, and removing them by a neutralization reaction or the like.

The aldehyde compound used in the deodorizing cartridge for the train storage type toilet of the present invention has sterilizing power,
It is necessary because it prevents deterioration due to the growth of bacteria in the cartridge or has reactivity with ammonia, and specifically, formaldehyde, glyoxal, glutaraldehyde, benzaldehyde and the like are preferable. As the organic acid, tartaric acid, maleic acid, malic acid, citric acid and the like are preferable, and they are necessary for neutralizing and removing with ammonia, and the saturated aqueous solution is preferable as the impregnating aqueous solution concentration. Each impregnated particle has an aldehyde compound impregnated particle of 50 to 75.
If the content is less than 50% by weight, the performance is not sufficient because it volatilizes, and even if it exceeds 75% by weight, it does not change.
The organic acid-impregnated particles are preferably 25 to 50% by weight,
If it is less than 5% by weight, the neutralization reaction is short in time and 50% by weight.
It does not change even if it exceeds. The size and capacity of the container can be freely changed depending on the size of the exhaust port and toilet tank,
0.7 g / l or more is required, and if it is less than 0.7 g / l, there is no time.

Next, the deodorizing cartridge for a train storage type toilet of the present invention will be specifically described by way of examples, but the present invention is not limited thereto.
