A waste incineration system for synergistically treating large-volume low-concentration waste gas and small-volume high-concentration waste gas and a method for operating the same

Abstract

The application discloses a kind of synergistically processing large wind volume low concentration waste gas and small wind volume high concentration waste gas incineration system and its operating method, in the method, high concentration waste gas and low concentration waste gas are not premixed in advance, set up separate incineration chamber for processing high concentration waste gas, incineration chamber is not set up regenerative bed, built-in burner, burner is high concentration waste gas as fuel, with low concentration oxygen-containing waste gas as combustion-supporting wind.Set up three regenerative incineration chambers for processing low concentration waste gas, each regenerative incineration chamber inlet and outlet are provided with lift valve, when normal operation, the opening and closing of each lift valve is controlled by time sequence, one is as air inlet chamber, one is as air outlet chamber, one is as purging chamber.In this way, it is ensured that all waste gas can be discharged up to standard, and the safety and cost optimization of operation process are ensured.The safety hazard and high energy consumption problems existing when traditional RTO technology simultaneously processes high concentration and low concentration waste gas are solved.
