| titleOfInvention | Air filter for CEMS gas analyzer |
| abstract | The utility model belongs to the technical field of air filtering equipment, and particularly relates to an air filtering device for a CEMS gas analyzer, which comprises a filtering box, wherein an inner groove is arranged on the upper end surface of the filtering box, three uniformly distributed mounting notches are formed in the bottom end inside the inner groove, filtering frames are movably inserted into the three mounting notches, a supporting plate is fixedly connected to the bottom end inside the filtering box, clean and dry compressed air which is dust-free, rust-free, oil-free and water-drop-free is obtained through two-stage filtering, the normal operation of the analyzer is guaranteed, the service life of the equipment is prolonged, finally the compressed air passes through a third filtering layer which is a zeolite molecular sieve, the air can be dried, pollutants in the air are purified, the problems that the existing air filtering device for the CEMS gas analyzer is poor in filtering effect and is easy to generate abnormal nitrogen oxide data are solved, the phenomenon that the zero drift is large and the automatic recovery in the daytime influences the normal operation of the analysis work. |
