AI Technical Summary
The filters of existing carbon emission monitoring samplers are prone to clogging, which can lead to gas path blockage, affect gas flow efficiency, and frequent filter removal can shorten the equipment lifespan.
The design employs a backflush cleaning system for the first filter. The airflow direction of the inlet and outlet pipes is adjusted by a rotating plate and a telescopic rod, allowing for cleaning without disassembling the filter. A seal is achieved using a one-way inlet and one-way outlet to prevent impurities from entering the sampler.
It effectively solved the problem of filter clogging, extended the service life of the equipment, simplified the operation process, and ensured the accuracy of sampling and the reliability of the equipment.
