Embodiment Construction

[0030] See figure 1 , figure 2 . The fumigation gas simulation fumigation device consists of a closed stainless steel box with a sandwich structure made of stainless steel and a function control box for the control and operating system on the outside of the closed stainless steel box (the closed box and the function control The shell of the box can be an integral structure); wherein the inner tank of the airtight box is at a 90-degree right angle up and down, and a circulating fan is installed in the airtight stainless steel box.

[0031] The interlayer between the inner tank and the outer shell of the airtight stainless steel box is filled with thermal insulation materials; one sampler is respectively opened on the upper and lower walls of the inner tank of the airtight stainless steel box and the middle of one side wall to penetrate the thermal insulation material and the outer shell. Port 5; on the upper wall and the middle part of the side wall of the airtight stainless...

Abstract

The invention relates to a fumigation simulation device for fumigation gas which comprises a closed box body of sandwich structure with an airtight gate and a function control box which is arranged outside the closed box body and is used for accommodating a control and operation system. An interlayer between a liner and an outer casing of the closed box body is filled with insulation material. An upper wall, a lower wall and a lateral wall of the liner are respectively provided with a sampler port penetrating the insulation material and the outer casing and are provided with an injection air hatch, a counter sample air hatch, an air inlet with a seal valve, an exhaust air outlet. A front panel of the function control box for accommodating the control and operational system comprises a color touch screen which is connected with a microcomputer control system, a data interface and a power switch and an injection air hatch, a counter sample air hatch and three sampler ports which are all provided with a pneumatic rapid joint. Fumigation air is injected into the closed box body by the injection air hatch and led out of the closed box body by the sampler port, and the fumigation air which is led out of the closed box body can be injected into the closed box body to circulate again through the counter sample air hatch.

Description

technical field [0001] The invention belongs to the technical field of fumigation, in particular to a fumigation gas simulation fumigation device used for detecting and analyzing fumigation gas during experiments. Background technique [0002] Currently used fumigants mainly include methyl bromide, ethylene oxide, sulfuryl fluoride, and phosphine, which are used for insecticide, rodent control, and disinfection of grain, plants, containers, and vehicles. Fumigant dosage, concentration, action time, safe air release time after fumigation, etc. are the main factors that determine the fumigation effect and ensure the safety of workers. A large number of studies, simulated fumigation experiment is the most commonly used experimental method. [0003] At present, there are two types of devices commonly used in simulated fumigation experiments: the one is a simple airtight box, such as the sulfuryl fluoride fumigation experimental research carried out by Xie Jianbo (China Frontier...
