[0029] Through the above settings, the gas boiler flue gas detection device of this embodiment uses spectral analysis technology to detect and analyze the flue gas components in the boiler and remotely detects online, thereby ensuring the optimal boiler flue gas emission, thereby achieving the purpose of environmental protection. The specific working process of the device is: the flue gas of the gas boiler passes through the filter component 2, the smoke inlet pipe 7, the condensation riser 12, the connecting pipe 8 and the spectrum analyzer 5 in sequence under the action of the aspirator 3, and the flue gas is finally discharged from the discharge port 51 of the spectrum analyzer 5. The impurities in the flue gas are filtered by the filter component 2, the flue gas is condensed by the condenser 1, the spectrum analyzer 5 detects the flue gas, and the flue gas after the detection is completed is discharged from the discharge port 51; the flue gas composition data analyzed in the spectrum analyzer 5 is uploaded to the server through the wireless network for the staff to judge and make corresponding correct operations, so as to realize real-time online monitoring of the flue gas.

[0032] In a gas boiler smoke detection device of this embodiment, the filter component 2 includes: a first filter 21 and a second filter 22, a coarse filter screen is arranged on the first filter 21, and a fine filter screen is arranged on the second filter 22, the air inlet end of the first filter 21 is connected to the smoke collection hole on the gas boiler chimney, the exhaust end of the first filter 21 is connected to the second filter 22, and the exhaust end of the second filter 22 is connected to the aspirator 3.

The temperature sensor 14 and the refrigeration assembly 4 are electrically connected to the controller 6. When the temperature sensor 14 detects that the temperature of the condensate is higher than 0 degrees Celsius, the refrigeration plate 41 is controlled to refrigerate.

[0042] In a gas boiler smoke detection device of this embodiment, the refrigeration assembly 4 and the aspirator 3 are both electrically connected to the controller 6. Specifically, the refrigeration fins 41 and the fan 43 are electrically connected to the controller 6.

[0043] The specific working process of a gas boiler smoke detection device of this embodiment is as follows: the smoke of the gas boiler enters the filter assembly 2 through the pipeline under the action of the suction pump to filter out dust and part of the water vapor, and the filtered gas passes through the condensation riser 12, and the remaining water vapor is removed under the action of the condensate in the condensation chamber 11, and the generated condensed water is discharged through the drain 71. The processed smoke is analyzed for smoke components by the spectrometer 5, and the smoke component data is uploaded to the server.
