Description

Technical Field

[0001] The utility model relates to the technical field of gas organic volatile monitors, in particular to a gas organic volatile monitor. Background Art

[0002] With the development of the economy, industrial gas pollution is becoming more and more serious, and gas monitoring of conventional industrial pollution has always been a monitoring focus. Organic volatile gases TVOC, sulfur dioxide, ammonia, ozone, hydrogen sulfide, nitrogen dioxide, nitric oxide, carbon dioxide, sulfur dioxide, methyl sulfide, methyl mercaptan, carbon disulfide, etc. are all key monitoring objects. It is necessary to monitor the gaseous organic volatiles, so a monitor is needed. When the existing monitor is in use, the gaseous organic volatiles enter the monitor from the intake pipe for detection. After the monitoring is completed, the gas is discharged from the exhaust pipe. However, the existing gaseous organic volatiles will carry certain impurities, which will block the air inlet of the monitor for a long time. The existing monitor cannot filter the impurities. Therefore, we propose a gas organic volatile monitor. Utility Model Content

[0003] The purpose of the utility model is to provide a gas volatile organic matter monitor to solve the problems raised in the above background technology.

[0005] Furthermore, the outer wall of the first air intake pipe is provided with a first external thread, the outer wall of the second air intake pipe is provided with a second external thread, and the inner walls of the two groups of connecting pipes are provided with internal threads meshing with the first external thread and the second external thread.

[0006] Furthermore, the filter holes of the two groups of filter screens decrease in sequence from right to left.

[0007] Furthermore, the filter tube and the two groups of connecting tubes are integrally formed.

[0008] Furthermore, the inner wall radius of the connecting tube is greater than the inner wall radius of the filtering tube.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can filter impurities in the gas entering the monitor body with the cooperation of the filter tube and two sets of filter screens with different filter holes, and the filter tube can be easily disassembled with the cooperation of the connecting pipe, the internal thread, the first external thread and the second external thread, so as to facilitate the cleaning of impurities on the surface of the filter screen.
