Description

Technical Field

[0001] The utility model relates to the technical field of flue gas analyzers, and more specifically to a flue gas analyzer which is easy to clean. Background Art

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. Gases include water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, and smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. In order to improve environmental protection, it is necessary to use special analytical equipment to detect the emitted flue gas to avoid the emission of flue gas that does not meet the emission requirements.

[0003] Based on the above, the inventors found that when the existing flue gas analyzer analyzes the flue gas, the flue gas needs to be sucked into the inside of the instrument, and the flue gas needs to be filtered and processed to prevent dust and impurities from entering the electrolyte. However, the filtering structure inside the instrument is usually fixed by multiple bolts, and the disassembly operation is cumbersome and inconvenient to clean. If it is not cleaned in time after use, it is easy to block the flue gas detection channel, affecting the next detection and use. Therefore, in view of this, the existing structure is studied and improved to provide a flue gas analyzer that is easy to clean, in order to achieve the purpose of having more practical value.
