Detailed Description
The invention will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the invention.
As shown in fig. 1 and 2, an online particulate monitoring instrument includes a host 1 and a sampling probe 2; the host 1 and the sampling probe 2 are detachably connected, and the host can be conveniently transported in a detachable connection mode. Specifically, a first mounting flange 11 is arranged on the main machine 1; a second mounting flange matched with the first mounting flange 11 is arranged on the sampling probe 21; the first mounting flange 11 and the second mounting flange 21 are connected through bolts, so that the sampling probe 2 can be conveniently disassembled and assembled, and a sealing ring and the like are further arranged at the joint between the first mounting flange 11 and the second mounting flange 21. The utility model discloses a be connected between host computer 1 and the sampling probe 2 and do not utilize the heat tracing pipe to be connected for the stroke of sample pipeline is short, and the difficult deposit of particulate matter, and owing to do not have the heat tracing pipe that exposes outside, thereby also need not heat to this heat tracing pipe and keep warm, made things convenient for the use.
The main machine 1 comprises a box body 7 and a gasification chamber 3 which is arranged in the box body 7 and is connected with the sampling probe 2.
