Embodiment Construction
[0041] The present invention will now be described in further detail in conjunction with the accompanying drawings and examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention. The structures, connections and methods not described in detail in the patent of the present invention can be understood as common knowledge in the field.
[0042] Such as Figure 1-7 As shown, an incineration flue gas wet deacidification device is characterized in that it includes a cooling tower 1, a wet scrubber 2, an acid mist condenser 3, an induced draft fan 5, a flue gas reheater 4, and an exhaust pipe 6, The six are connected sequentially through pipelines.
[0043] The cooling tower 1 is an FRP hollow cylinder. FRP high-temperature-resistant, acid-alkali-resistant glass fiber reinforced plastics are used to improve the high-temperature-resistant, acid-alkali-resistant effects of the cooling tower 1 .
[0044] The c...

The invention relates to a wet-process deacidification device for incineration flue gas. The wet-process deacidification device comprises a cooling tower, a wet-type washing tower, an acid mist condenser and a flue gas reheater, wherein the cooling tower, the wet-type washing tower, the acid mist condenser and the flue gas reheater are sequentially connected through pipelines; an in-tower circulating liquid tank, a gas inlet, a gas distributor, a filler, a spraying system, a gas distributor, a demisting layer and a gas outlet are arranged in the wet-type washing tower from bottom to top; thespraying system and the in-tower circulating liquid tank are both communicated with an out-tower outer circulating liquid tank; the cooling tower is a double-layer falling-film wet-wall tower; the acid mist condenser is a horizontal tower and is provided with a spraying system capable of achieving opposite spraying. According to the invention, high-efficiency wet-process deacidification is achieved through stable absorption of the filler, dehumidification and demisting, meanwhile the emission reduction effects on water vapor, acid mist, salt mist and solid particulate matters are achieved, andcontribution is made to haze decrease. In addition, by cooling and dehumidifying of the wet-type washing tower, condensation of small liquid drops of the acid mist condenser and heating of the flue gas reheater, the purpose that white smoke is not generated at the discharging port is achieved.
Description
technical field [0001] The invention relates to the field of environmental protection, in particular to an incineration flue gas wet deacidification device and a flue gas deacidification process. Background technique [0002] The traditional method of solid waste (including garbage or hazardous waste) incineration plants is semi-dry method + dry method + flue gas whitening device to remove harmful substances to meet emission standards and eliminate white smoke during emission. However, as environmental protection requirements become more and more stringent, this method cannot meet the requirements of the process. The important pollutants in the flue gas of solid waste incineration are SO 2 And HCL, HF and other acid substances. In recent years, wet deacidification technology has been applied more and more in the incineration and detoxification of solid waste (garbage and hazardous waste), but most of them are in the initial application stage, and the emission effect and wh...
