Description

The present invention relates to a fumigant vaporizer, more specifically, by a direct heating method to quickly vaporize a fumigant that can be widely used for agriculture or quarantine by insecticidal, sterilizing, and herbicidal effects. It relates to a smoke vaporizer that can be used.

The fumigant is a general term for volatile chemicals used to kill pests and hospital bacteria, that is, chemicals.

Generally, since fumigants have insecticidal, bactericidal and herbicidal effects, they are widely used for agriculture or quarantine.

Such fumigants are known to include hydrogen cyanide, calcium cyanide, carbon dioxide, sulfurous acid gas, chloropicrin, carbon tetrachloride, ethylene dichloride, ethylene dibromide, p-dichlorobenzene, γ-BHC and the like. Used for insecticidal and sterilization of warehouses, ships, fruit trees, soil, etc.

If a large amount of fumigant remains in the soil, the soil will be contaminated, and if the warehouse, ships, etc. are sterilized and washed with water, the fumigant is contained in the water and pollutes the water quality. Follow

When using a fumigant, it is common to heat a liquid fumigant into a fumigant, and then supply the fumigant to fumigants such as warehouses, ships, fruit trees, and soil.

On the other hand, it is said that methyl bromide is extremely common in the present fumigant use technology.

However, in the case of methyl bromide, which is known as a substance that destroys the ozone layer, it is common to administer a fumigated substance through a simple vaporizer in order to reduce chemical damage to low-temperature treatment and fumigants. There is a problem that the incidence of worker safety accidents is increasing due to the residue of unvaporized fumigated substances remaining in the lake after the substance is dispensed.

On the other hand, in the case of the fumigant (EF+CO ₂ mixed high-pressure gas) developed as a substitute for methyl bromide, the vaporizer is used due to the freezing phenomenon of the gas tube at the time of use, but it is expensive because the mixed gas is charged at high pressure. Not only is it sold and distributed, but the problem is that the gas cylinder itself is heavy and can cause a safety accident for the fumigation operator.Therefore, technical development of the fumigation apparatus considering such matters is required. It is a necessary reality.

Further, the conventional fumigant vaporizer has a disadvantage due to the limited amount of use when using ethyl formate as a fumigant. That is, in the case of fumigation on a large scale, in order to continuously use the fumigation after one setting, it is necessary to stop the mechanical device and then set it again.

Furthermore, the fumigant administration time becomes long, which makes inconvenient work at the site, and when the fumigant is weighed and fired at the site, it may be left dangerous. Further, there is a problem that the fumigation machine is not downsized.
