Description of drawings:
Fig. 1 is the structural representation of the utility model.
Label among the figure: 1 wet shotcrete technology atomizing layer, 2 keep away the separated form water cap, 3 jet atomization layers, 4 jet atomization eddy flow plates, 5 carbonated drink separating plates, 6 columns, 7 guiding gutters.
Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.
The specific embodiment:
Embodiment: referring to the dust-removal and desulfurizing combination tower of Fig. 1 present embodiment; Be provided with in the combination tower and keep away separated form water cap 2; The bottom of combination tower is provided with the ash-laden gas inlet; Be provided with wet shotcrete technology atomizing layer 1, jet atomization layer 3, jet atomization eddy flow plate 4, carbonated drink separating plate 5 in the combination tower above smoke inlet successively, the top of combination tower is communicated with air-introduced machine and chimney successively; The separated form water cap 2 of keeping away of being located at wet shotcrete technology atomizing layer 1 top is divided into combination tower the two parts that are communicated with up and down; The bottom is a wet shotcrete technology nebulization dust absorber portion; Top is jet atomization eddy flow plate desulfurization absorber portion; Keeping away separated form water cap 2 is that axis is the cap shape and stretches with the center stand column in the combination tower 6, keeps away between the inwall of edge and combination tower of separated form water cap 2 to have the gap.
In specifically being provided with, wet shotcrete technology atomizing layer 1 comprises that along radially-arranged water pipe of combination tower and atomizer, jet atomization layer 3 comprises the water pipe and the atomizer of radially arranging along combination tower equally; Jet atomization eddy flow plate 4 is connected between column and the combination tower inwall, and the top of jet atomization eddy flow plate is provided with wash tub pipe; Carbonated drink separating plate 5 is connected between column and the combination tower inwall, and the top of carbonated drink separating plate is provided with wash tub pipe; Above wet shotcrete technology atomizing layer 1, be provided with the guiding gutter 7 that is connected the combination tower inwall, the edge of keeping away separated form water cap 2 is in the top of guiding gutter 7.
