Combustible gas detection exhaust system for solvent ink production workshop

The utility model discloses a combustible gas detection exhaust system for a solvent ink production workshop, which can automatically detect the concentration of combustible gas in the solvent ink production workshop and automatically realize exhaust and alarm. The system comprises at least one combustible gas detector, a middle relay, a contactor and at least two exhaust fans; the signal output end of the combustible gas detector is connected with the middle relay, the output end of the middle relay is connected with the input end of the contactor, and the power supply input end of each exhaust fan is connected with the power supply output end of the contactor; the combustible gas detector can be used for directly detecting the concentration of the combustible gas in the workshop; when the concentration of the combustible gas in the workshop exceeds a preset value, the combustible gas detector outputs electrical signals to the middle relay, the middle relay works and transmits the signals to the contactor, t
