Description

Technical Field

[0001] The utility model relates to the technical field of flue gas samplers, in particular to a dual-path flue gas sampler for environmental detection. Background Art

[0002] Environmental testing uses GIS technology to design an environmental testing network. The information collected by environmental testing can be stored and displayed in a timely manner through GIS, and detailed site monitoring and analysis can be performed on the selected evaluation area. Sampling is required through flue gas samplers in environmental testing. Compared with single-channel flue gas samplers, dual-channel flue gas samplers are more comprehensive in function and can control each channel separately. However, after long-term use, the current dual-channel flue gas samplers are prone to accumulation of dust particles in the flue, which is difficult to clean and easily affects the accuracy of the next test.

[0003] In order to solve the above problems, the prior art proposes a self-cleaning dual-path flue gas sampler with patent announcement number CN218496530U, which is convenient for completing the sampling of flue gas by connecting an air intake mechanism at the top, and is convenient for supporting and fixing the air intake mechanism by installing a supporting mechanism for supporting the air intake flue on the outside of the air intake flue. At the same time, a cleaning mechanism and a flushing mechanism are installed on the top of the load-bearing platform. The mutual cooperation between the cleaning mechanism and the flushing mechanism facilitates the cleaning of the interior of the air intake flue. Although it is convenient for cleaning the interior of the flue, the cleaning mechanism and the flushing mechanism will occupy the space in the air intake flue, which will affect the air intake efficiency of the flue gas entering the air intake flue, thereby affecting the sampling effect during environmental testing.
