Abstract

The utility model relates to an incineration system capable of incinerating organic waste liquid and waste gas at the same time, which is composed of a vertical cyclone incinerator, a waste heat recovering device and a washing tower, and the key equipment of the utility model is the vertical cyclone incinerator. A powder coal nozzle burner is arranged on the incinerator and adopts powder coal to support combustion, and the operation cost is decreased; the top of a hearth is provided with a demisting plate, and the molten salt generated by incineration is intercepted by the demisting plate and accumulated at bottom of the incinerator and then discharged through a tap hole. Anticlockwise tangential entering primary air and clockwise tangential entering secondary air form two cyclones to cause a high-temperature region in the incinerator to be agitated violently, and the incineration efficiency is improved. A waste gas nozzle burner is arranged in the position of 90 DEG of a waste liquid atomizing nozzle combustor, and the waste liquid and the waste gas can be incinerated crosswise or simultaneously. Each waste liquid atomizing nozzle combustor can handle two tons per hour; when the handling capacity is big, a plurality of waste liquid atomizing nozzle combustors can be installed, the volume of the hearth is increased correspondingly, and the stay time of the waste liquid is prolonged correspondingly. The system can deal with high-concentration organic waste liquid and waste gas and has high salt elimination rate and low powder coal combustion supporting cost; the waste heat recovery saves the energy.
