Description

Fumigation Apparatus

The present invention relates to a fumigant vaporizer, and more particularly, to a fumigant vaporizer capable of vaporizing a fumigant which can be widely used for agricultural or quarantine purposes, The present invention relates to a fumigant vaporizer.

A fumigant is a generic term for a volatile drug, or chemical, used to kill insects or pathogens.

Generally, fumigants are widely used for agricultural or quarantine purposes because they have insecticidal, bactericidal and herbicidal effects.

It is known that these fumigants include hydrogen cyanide, calcium cyanide, carbon dioxide, sulfur dioxide, chloropicrin, carbon tetrachloride, ethylene dichloride, ethylene bromide, p-dichlorobenzene, It is used for insecticide and sterilization of soil.

Of course, if fumigants remain in the soil in large quantities, the soil will be contaminated. If the fumigants and ships are sterilized and washed with water, they will be contained in the water and pollute the water quality.

When the fumigant is used, it is common to heat the liquid fumigant to produce a fumigant, and then supply the fumigant to a fumigant such as a warehouse, ship, fruit tree, soil or the like.

On the other hand, it is known that the current technology of using fumigants is very common to use methyl bromide.

However, in the case of methyl bromide, which is known to be an ozone-depleting substance, most of the fumigants are administered with fumigating agents through a simple vaporizer in order to alleviate the weakness in the low-temperature treatment or the fumigant, There is a problem that a safety accident of workers is caused due to the remaining amount of unburned fumed vaporized material.

On the other hand, in the case of the fumigant (EF + CO2 mixed high-pressure gas) developed as a substitute for methyl bromide, the vaporizer is used due to the freezing of the gas tube in use, but the mixed gas is charged at high pressure, However, since the gas cylinder itself is heavy, there is a problem that a safety accident of a fumigant may occur. Therefore, it is necessary to develop a technology of a fumigant vaporizer considering these considerations.
