Further, bypass duct 2 described in the utility model is arranged on outside exhaust gas inlet pipeline 1 and catalysis direct combustion room 6 side by side.Specifically, on the entrance of the described bypass duct 2 exhaust gas inlet pipeline 1 between filter 11 and exhaust gas inlet valve 12, export on the exhanst gas outlet pipeline 7 between exhanst gas outlet valve 71 and air-introduced machine 8.
Further, flue gas recirculation pipeline 3 described in the utility model be connected to air-introduced machine 8 export exhanst gas outlet pipeline 7 and surge tank 14 after exhaust gas inlet pipeline 1 between.The gas that described air-introduced machine 8 is discharged is divided into two-way, lead up to aiutage discharged to air, flue gas recirculation pipeline of leading up to access exhaust gas inlet pipeline 1, is together introduced catalysis direct combustion room 6 with waste gas, is controlled the flow of flue gas recirculation pipeline 3 by flue gas recirculation valve 31.
Further, the through hole level of described heat storage layer 67, namely along the length direction of catalysis direct combustion room 6, every layer of heat storage floor 67 all fills up the longitudinal cross-section of catalysis direct combustion room 6, and air-flow can only flow in through-holes.More than one times that is spaced apart single heat storage thickness between adjacent heat storage layer 67, preferably 1-3 doubly.Object be make air flow energy evenly the longitudinal cross-section being distributed in catalysis direct combustion room 6.The gross thickness of heat storage floor 67 is the 10%-40% of catalysis direct combustion room 6 length.
The course of work of the present utility model comprises purging, heats up, the four-stages such as operation and shutdown.First carry out purge stages: air inlet valve 41 and air outlet valve 51 are opened, and air-introduced machine 8 is opened, exhaust gas inlet valve 12, exhanst gas outlet valve 71 and flue gas recirculation valve 31 are closed, and bypass valve 21 is according to or without VOCs toxic emission opening and closing.VOCs residual in main catalytic oxidant layer 66, heat storage floor 67 and auxiliary catalysis oxidant layer 68 is blown out catalysis direct combustion room 6 by the air that air-introduced machine 8 is introduced.
After purge stages, enter the temperature rise period: auxiliary burner 65 is lighted a fire, by the air heat in catalysis direct combustion room 6, along with the flowing of air in catalysis direct combustion room 6, main catalytic oxidant layer 66, heat storage layer 67 and auxiliary catalysis oxidant layer 68 heat up successively; After the temperature of auxiliary heat galvanic couple 63 detection reaches setting value, the temperature rise period terminates, and the operation phase starts.
In operation phase, exhaust gas inlet valve 12 and exhanst gas outlet valve 71 are opened, and air inlet valve 41, air outlet valve 51 and bypass valve 21 are closed, and VOCs waste gas enters catalysis direct combustion room 6, and main burner 61 is lighted a fire, and auxiliary burner 65 stops working.VOCs waste gas is heated by main burner 61, and by there is catalytic reaction during auxiliary catalysis oxidant layer 68, VOCs is decomposed into carbon dioxide and water and heat release, and waste gas becomes free of contamination heat smoke; Heat smoke flows through heat storage layer 67 and main catalytic oxidant layer 66, and they is heated; Flue gas flows out catalysis direct combustion room 6, enters air through air-introduced machine 8 and aiutage 9; When main thermocouple 64 detect temperature be elevated to setting value time, main burner 61 stops working, and now auxiliary catalysis oxidant layer 68 and heat storage layer 67 still have higher temperature, can continue heat exhaust gases, and the VOCs after heating is decomposed by during main catalytic oxidant layer 66; Along with auxiliary catalysis oxidant layer 68 and heat storage layer 67 are cooled by waste gas, prescribe a time limit close to the lower of main catalytic oxidant layer 66 decomposition temperature when main thermocouple 64 detects EGT, main burner 61 is lighted a fire again, starts next circulation.When the best air quantity scope that exhausted air quantity works lower than catalysis direct combustion room 6, flue gas recirculation valve 31 is opened, and the flue gas that part flows out air-introduced machine 8 enters catalysis direct combustion room 6, remains in optimum range to make its air quantity and temperature.The exhaust gas volumn of recirculation is regulated by flue gas recirculation valve 31.When breaking down in catalysis direct combustion room 6, bypass valve 21 is opened, and exhaust gas inlet valve 12, flue gas recirculation valve 31, air inlet valve 41, air outlet valve 51 and exhanst gas outlet valve 71 are closed, and waste gas directly enters air by air-introduced machine 8 and aiutage 9.
