Description

Technical Field

[0001] The utility model relates to the technical field of methyl bromide vaporizers, in particular to a vaporizer for fumigating methyl bromide with a dosing structure. Background Art

[0002] Methyl bromide is one of the more commonly used agents in fumigation treatment at my country's ports. It has the characteristics of strong permeability and is also the designated agent for fumigation of imported and exported goods internationally. Methyl bromide is generally processed into bottled liquefied gas for use at various ports. During the application process, it is necessary to rely on the pressure in the cylinder to output a certain amount of liquid methyl bromide from the pipeline port, and then transport the liquid methyl bromide to the fumigation space through the application pipe and quickly vaporize it to fill the fumigation space, thereby achieving the purpose of fumigation treatment.

[0003] The patent with publication number CN204616869U discloses a vaporizer for fumigating methyl bromide. The vaporizer is provided with a liquid inlet and a liquid outlet, which is convenient for replacing different heat transfer oils or other heat transfer materials at any time. A stirring device is provided in the container. During the heating process, stirring is used to make the heat transfer material more evenly heated, thereby accelerating vaporization. However, due to its structural reasons, the amount of methyl bromide that can be added per unit time is relatively small when vaporizing methyl bromide through a coil, and the pressure in the pipeline increases during the vaporization process, making it difficult to feed materials, thereby further reducing the efficiency of vaporization, and further improvement is needed.
