Summary of the invention:
For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of dust-removal and desulfurizing combination tower, and existing dedusting and desulfurizing tower inside is divided into two: the bottom is a wet shotcrete technology nebulization dust absorber portion, and top is jet atomization eddy flow plate desulfurization absorber portion.Dedusting liquid, doctor solution separately are recycled to precipitate and separate system separately respectively, handle back recirculation and use.
The utility model technical solution problem adopts following technical scheme:
A kind of dust-removal and desulfurizing combination tower; The bottom of said combination tower is provided with the ash-laden gas inlet that is communicated with venturi; Be disposed with the wet shotcrete technology atomizing layer in the said combination tower from bottom to top, keep away the separated form water cap, jet atomization layer, jet atomization eddy flow plate, carbonated drink separating plate, the top of said combination tower is communicated with air-introduced machine and chimney successively;
The said dedusting absorber portion of keeping away the separated form water cap with desulfurization absorber portion that is divided into top in the said combination tower and bottom, said wet shotcrete technology atomizing layer comprises the water pipe and the atomizer of radially arranging along combination tower; The center of said combination tower is provided with column, and the said separated form water cap of keeping away is that axis is the stretching, extension of cap shape with said column; Said jet atomization layer comprises the water pipe and the atomizer of radially arranging along combination tower; Said jet atomization eddy flow plate is connected between said column and the said combination tower inwall, and the top of jet atomization eddy flow plate is provided with wash tub pipe; Said carbonated drink separating plate is connected between said column and the said combination tower inwall, and the top of carbonated drink separating plate is provided with wash tub pipe;
The top of said wet shotcrete technology atomizing layer is provided with the guiding gutter that is connected the combination tower inwall, and the said edge of keeping away the separated form water cap is in the top of said guiding gutter.
Compared with present technology, the beneficial effect of the utility model is embodied in:
1, prior dedusting desulfurization combination tower inside is divided into two: bottom wet shotcrete technology nebulization dust absorber portion, top are jet atomization eddy flow plate desulfurization absorber portion.Dedusting liquid, doctor solution separately are recycled to precipitate and separate system separately respectively, handle back recirculation and use.
2, improve utilization ratio of device, optimized technology.
3, realized handling dedusting liquid, separating of doctor solution, improved precipitate and separate and oxidation regeneration ability, helped the recycling of solution.
4, practiced thrift regenerating medium like the consumption of materials such as lime, alkali.
5, farthest reduced secondary pollution to the greatest extent.
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 Fig. 1; The dust-removal and desulfurizing combination tower of present embodiment; Its underpart is provided with the ash-laden gas inlet that is communicated with venturi; Be disposed with wet shotcrete technology atomizing layer 1 in the combination tower from bottom to top, keep away separated form water cap 2, jet atomization layer 3, jet atomization eddy flow plate 4, carbonated drink separating plate 5, the top of combination tower is communicated with air-introduced machine and chimney successively.
In specifically being provided with, keep away the dedusting absorber portion of separated form water cap 2 with desulfurization absorber portion that is divided into the top that is interconnected in the combination tower and bottom, wet shotcrete technology atomizing layer 1 comprises the water pipe and the atomizer of radially arranging along combination tower; The center of combination tower is provided with column 6, and keeping away separated form water cap 2 is that axis is the stretching, extension of cap shape with column 6; The jet atomization layer comprises the water pipe and the atomizer of radially arranging along combination tower; 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.
The utility model operation principle: boiler, kiln ash-laden gas at first tangentially rotate into the dedusting absorber portion of dust-removal and desulfurizing combination tower bottom; Absorbed by the comprehensive interception of top-down jet atomization dedusting liquid; Overwhelming majority dust is removed at this, and sulphur is also further purified.The dedusting absorption liquid is discharged by the dedusting absorber portion bottom of dust-removal and desulfurizing combination tower bottom and is got into the special-purpose sedimentation basin of dedusting liquid, carries out Ash Water Separator, and the buck after the clarification continues to recycle.Flue gas through dust-removal and desulfurizing combination tower bottom wet shotcrete technology atomizing absorber portion also will (separate cap dedusting and desulfurizing tower is divided into bottom master's dedusting section and top master's desulfurization section effectively through keeping away the separated form water cap.The doctor solution that simultaneously gets off top master's desulfurization section is guided to the water conservancy diversion liquid bath; Be recycled to the doctor solution treatment system separately) and the combination tower inwall between the gap get into the further absorption cleaning of desulfurization absorber portion on desulfurization combination tower top; The moisture film that doctor solution forms on jet atomization eddy flow plate receives the impact of high speed flue gas, in plate, forms fluidized, strong the mixing of gas-liquid two-phase brush; Increased the mass transport process of gas-liquid; Desulfuration efficiency improves greatly, and the residual dirt in the flue gas is further removed simultaneously, and the desulfurization absorption liquid is separated to guiding gutter 7 extraction systems through keeping away the separated form water cap; Be recycled to doctor solution oxidation regeneration pond and carry out oxidation regeneration, the absorbability continued of recovering doctor solution recycles.Flue continue rotation rise get into carbonated drink separating spiral-flow plate and separate carbonated drink after, " labyrinth " the type steam trap that forms through reverse taper mushroom cap and rain visor again after forcing to separate carbonated drink, is introduced in the smoke stack emission atmosphere through air-introduced machine by flue.
