Problems solved by technology
[0002] In the detection of volatile organic compounds (VOCs), clean gas is used. This clean gas is mainly used in the establishment of standard curves, and the process of flushing the adsorption tube with clean nitrogen, especially when it is necessary to control the gas flow. The gas needs to pass through the flow meter, pressure reducing valve, rubber tube, etc., which will cause the gas to be polluted by the pipeline, which will affect the accuracy of the test result
[0003] At present, there is no equipment for this pollution situation, but in analytical chemistry, the gas can be filtered and purified by passing the gas through a filter bottle, such as a gas cylinder with activated carbon
But after passing through the filter bottle, on the one hand, the flow rate of the gas will be affected due to the resistance of the activated carbon; secondly, because the gas only passes through the activated carbon once, the filtration efficiency is low

Embodiment Construction
[0019] Accompanying drawing is a kind of specific embodiment of the present invention.
[0020] The gas purifier for detection of the present invention has a fully sealed structure as a whole, including a box body 9, the box body is provided with an air inlet 7 and an air outlet 8, and several layers of filter grids are arranged inside the box body to divide the internal space into A plurality of small spaces, each layer of grids is placed with a layer of adsorbent packs 4 for filtering and purifying.
[0021] The filter grid includes partitions 5 and crossbeams 6. The partitions are installed inside the box, and there is a hollowed out part in the middle of the partition. A ring of sealing pads 1 is arranged between the adsorbent packages.
[0022] The filter grid is also provided with gas overflow holes 3 .
[0023] The filter grill adopts a drawer structure, which can be drawn and installed in the box for easy disassembly. A sealing gasket 1 is also provided at the contac...

The invention belongs to the field of detection and relates to a gas purifier for detection. The gas purifier for detection is characterized in that the gas purifier for detection is wholly of a sealed structure and comprises a box body, wherein the box body is provided with a gas inlet and a gas outlet, a plurality of layers of filer gratings are arranged inside the box body, the inner space is divided into multiple small spaces, and one layer of adsorbent bags having filtration and purification effects is arranged on each layer of gratings. The gas purifier for detection has the advantages of being low in cost, easy to operate, good in purification effect and small in resistance and can serve as a novel pretreatment device for gas purification and replace an existing activated carbon accumulation and filtration method or other methods or devices difficult to use.
Description
technical field [0001] The invention belongs to the field requiring special gas purification requirements in gas detection, and relates to a gas purifier for detection, which is mainly aimed at the purification of volatile pollutants.
