Description
Technical Field
The utility model relates to a waste incineration power plant gas cleaning technique particularly relates to a waste incineration gas cleaning processing apparatus of cigarette tower unification.
Background
At present, the flue gas purification treatment system of domestic waste incineration power plants is generally as follows: SNCR (non-selective catalytic reduction) + semi-dry method + active carbon + bag-type dust remover + chimney. With the stricter and stricter emission standards of the environmental protection department on pollutants, the flue gas purification treatment process has a limited pollutant removal effect, and particularly in regions with more severe environmental impact, the flue gas purification treatment process cannot meet the requirement of ultralow emission of pollutants, for example, aiming at denitration, only adopting an SNCR denitration configuration in a furnace cannot ensure that the concentration of NOx is not more than 10mg/Nm 3; aiming at acid gases such as HCl, SO2 and HF in the flue gas, the concentrations of HCl, SO2 and HF cannot be respectively guaranteed to be less than 5mg/Nm3, 10mg/Nm3 and 1mg/Nm3 by adopting the configuration of semidry deacidification and dry deacidification.
The smoke tower integrated technology is firstly suitable for coal-fired thermal power plants, originates from Germany, and is used for successively constructing a large number of smoke tower integrated projects in China by the domestic power groups such as Huaneng, Guoeo and Guoeo, but is rarely applied to garbage incineration power plants at present. The smoke of the existing waste incineration power plant is discharged through a chimney, and the construction of the power plant chimney is the key and difficult point of civil engineering construction. This is because: firstly, geological exploration and foundation treatment in a chimney area are high in cost, and the working period of chimney construction in power plant civil engineering is long. Secondly, in order to ensure the qualified ground concentration of the discharged flue gas, the chimney must meet a certain height, and when the waste incineration power plant is built in certain height-limited areas, the conventional chimney smoke discharging process cannot meet the requirement. In addition, for the areas which partially need chimney de-whitening, a steam heater is additionally arranged to ensure that the temperature of the clean flue gas reaches an unsaturated temperature range.
Therefore, there is a need to provide a smoke-tower integrated waste incineration smoke purification device to overcome the above disadvantages.
