Direct combustion device is the use of auxiliary fuel, in a specific environment ( combustion furnace ), combustion and heat to establish a reaction environment, the exhaust gas containing organic substances directly into, at high temperature, the organic substances in the exhaust gas and oxygen in the air chemical reaction, organic substances are oxidized and decomposed into CO2 and H2O, and at the same time release heat energy, so as to achieve the removal of harmful substances in the exhaust gas, the reaction is exothermic reaction, oxidation
The organic exhaust gas to be treat enters that heat storage lay of the heat storage chamber 1 through the induced draft fan ( " store" the heat of the previous cycle ), the heat storage layer releases heat, the temperature is reduced, and the organic exhaust gas absorb heat, the temperature is increased, and the exhaust gas enters the oxidation chamber at a higher temperature after leaving the heat storage chamber, wherein the temperature of the exhaust gas depends on the volume of the heat storage layer, the flow rate of the exhaust gas and the geometry of the heat storage layer.
In the oxidation chamber, the organic exhaust gas is replenished by the burner and heated to a set oxidation temperature. The organic matter is decomposed into carbon dioxide and water. Since the exhaust gas has been preheated in the regenerator, the amount of fuel used by the burner is greatly reduced. The oxidation chamber has two functions: one is to ensure that the exhaust gas can reach the set oxidation temperature, and the other is to ensure sufficient residence time to fully oxidize the exhaust gas in the exhaust gas.
The exhaust gas flows through the heat storage chamber a to be heated and then enters the oxidation chamber for incineration, becomes purified high-temperature gas, leaves the oxidation chamber, enters the heat storage chamber b ( which has been cooled in the previous cycle ), releases heat, cools and then is discharged, and the heat storage chamber b absorbs a large amount of heat and then heats up ( which is used for heating the exhaust gas in the next cycle ). The treat gas leaves that heat storage cham b and is discharged into the atmosphere by a draught fan.
