Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to an air bag heating box. Background Art

[0002] The gas pretreatment automatic sampling device is a precision device used for pretreatment and automatic sampling of gas samples. Its main function is to perform a series of treatments on the collected gas samples, such as filtering, drying, and concentration, to meet the detection requirements of subsequent analytical instruments, and to achieve automatic, accurate, and repeatable sampling operations. This device usually has a high-precision flow control unit that can accurately control the flow rate and injection volume of the gas.

[0003] The existing gas pretreatment automatic sampling device will first put VOC into a professional air bag before gas sampling for storage and transportation. When the VOC is in the air bag, part of its gas will condense into water droplets due to the temperature and hang on the inner wall of the air bag. If the gas is sampled directly, not only will the VOC be wasted, but the water droplets will enter the gas pretreatment automatic sampling device and cause malfunctions. Therefore, it is necessary to develop an air bag heating device for use with the gas pretreatment automatic sampling device. Utility Model Content
