Description
Technical Field
The utility model relates to a flue gas deacidification equipment, in particular to waste incineration tail gas integration deacidification device.
Background
Waste incineration is a waste treatment method which has been vigorously developed in China in recent years. Due to the restriction of the components of the garbage, after the garbage is treated by an incineration process, the generated flue gas contains a certain amount of acid gases, such as HCl, SO2, HF, NOx and the like. Flue gas treatment processes commonly adopted in the construction of domestic waste incineration treatment projects include semi-dry deacidification, dry deacidification and wet deacidification, wherein the semi-dry deacidification and the dry deacidification are most commonly applied in the domestic waste incineration treatment projects.
The semidry deacidification method generally adopts calcium oxide (CaO) or calcium hydroxide (Ca (OH) 2) as a raw material to prepare a calcium hydroxide solution. And spraying the calcium hydroxide solution into the reactor by using a nozzle or a rotary sprayer to form liquid drops with extremely small particle size, and reacting with the acid gas. The water is completely evaporated in the reaction process, so no waste water is generated.
However, the removal rate of the deacidification device in the process is not broken through, the research and development speed is almost not before stagnation, the device is complex, the reaction control difficulty is high, and the cleaning difficulty of the device is also high.
