AI Technical Summary
Existing negative pressure samplers in power plant boiler furnaces cannot effectively crush larger particles, leading to clogging of the filter structure and affecting sampling results.
A negative pressure sampler for power plant boiler furnaces, including a drive assembly, was designed. The drive assembly crushes particulate matter, and the mechanical linkage design scrapes off impurities adhering to the surface of the filter cartridge, ensuring smooth gas flow.
It enables efficient sampling of samples inside the furnace of power plant boilers, prevents particulate matter blockage, ensures smooth gas flow, and provides protection for personnel.
