[0019] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0021] In the present application, unless otherwise stated, the orientation such as "up, down" is generally with respect to the direction shown in the drawings, or with respect to the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is generally with respect to the left and right shown in the drawings; "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application.

[0022] For example, Figures 1-3As shown, the application provides a dust removal and denitration integrated reaction tower, which comprises a reaction tower 1, a spray tower 2 arranged on one side of the reaction tower 1, and an induced draft fan 3 arranged between the reaction tower 1 and the spray tower 2. The inlet of the induced draft fan 3 is connected with the upper end of the reaction tower 1, and the outlet of the induced draft fan 3 is connected with the lower end of the spray tower 2.

[0023] The top end of the spray tower 2 is provided with a spraying device, the middle of the spray tower 2 is provided with a filter box 21, and the opposite sides of the filter box 21 are provided with a plurality of layers of filter assemblies 22.

[0024] One side of the filter box 21 is provided with a plurality of dew outlets 24 corresponding to the positions of the filter plates 23, and the side of the filter box 21 provided with the dew outlets 24 is fixedly installed with a cover plate 25. One end of the filter plate 23 passes through the dew outlet 24 and is fixed with the cover plate 25.

[0025] The filter assemblies 22 of adjacent layers are arranged in the gaps between the filter assemblies 22 of the upper layer.

[0026] The induced draft fan 3 is used for guiding the smoke in the reaction tower 1 to the spray tower 2, and the spraying device in the spray tower 2 sprays the denitration liquid to remove dust and denitrate the smoke.

[0027] The liquid sprayed by the spraying device first removes dust and denitrates the smoke above the filter box 21 in the spray tower 2.

[0028] When the denitration liquid passes through the filter box 21, the guide plates 221 are used to collect the falling liquid, so that the liquid is concentrated on the upper side of the filter plate 23, and the filter plate 23 filters out the impurities generated by dust removal and denitrification in the liquid, so that the filtered liquid continues to fall, so as to improve the dust removal and denitrification efficiency of the liquid falling to the lower section of the spray tower 2.

[0029] Since the filter assemblies 22 of the lower layer are located below the gaps between the filter assemblies 22 of the upper layer, on the one hand, the smoke needs to bypass each layer of filter assemblies 22 during the process of passing through the filter box 21, thereby reducing the passing speed of the smoke, prolonging the dust removal and denitrification time of the smoke, and ensuring the safety of smoke emission; on the other hand, the smoke is concentrated in the gaps between the filter assemblies 22, and the liquid falling from the filter assemblies 22 also passes through the gaps between the filter assemblies 22, so that the liquid can fully contact with the smoke, thereby improving the efficiency of dust removal and denitrification of the smoke.

[0030] The user can take out the filter plate 23 for replacement or cleaning by removing the cover plate 25, thereby achieving the effect of convenient maintenance.
