Abstract

The invention discloses a flue gas device for a hazardous waste incineration system. The flue gas device comprises a main combustion chamber, a secondary combustion chamber and a fan assembly, the upper end and the lower end of a hollow sealing piece are fixedly connected with an outer cylinder and a shell respectively, the hollow sealing piece is provided with through holes, the bottom of the shell is provided with a first air inlet hole, a second air inlet hole is formed in a fire blocking portion, a radial air distribution layer and a tangential air distribution layer are arranged on the side wall of an upper cavity, a third opening is formed in the upper wall of the upper cavity, the radial air distribution layer is provided with a radial air inlet hole, a tangential air inlet hole isformed in the tangential air distribution layer, a secondary combustion chamber waste liquid combustion-supporting machine is in communication with the radial air inlet hole, a cooling fan is in communication with the tangential air inlet hole, one end of a flue gas heater is in communication with the third opening, and the other end of the flue gas heater is in communication with an induced draftfan. The flue gas device has the advantages that the air speed of the flue gas can be effectively controlled, and the residence time of the flue gas can be improved.

Description

technical field [0001] The invention relates to the technical field of hazardous waste incineration, in particular to a smoke and air device used in a hazardous waste incineration system. Background technique [0002] At present, the treatment of hazardous waste is mainly incinerated by incinerators. Hazardous waste incineration technology is a high-temperature treatment technology. The toxic and harmful substances in hazardous waste are oxidized and pyrolyzed at high temperature and destroyed. , Reduction, and resource-based processing technology. [0003] In the incineration process, due to the complex thermal synthesis reaction, dioxin and its related compounds will be formed. In order to prevent dioxin and its related compounds from being directly discharged into the atmosphere, causing environmental pollution and harm to the human body , by setting up a flue air device to purify the dioxin and its related compounds in the rotary kiln, to ensure that the flue gas discha...
