Abstract
The utility model relates to a fume desulfurizing dust remover for a boiler. The top part of a cylinder is provided with a fume inlet, and the upper part of an inner cavity is provided with a distributing plate 12 and a baffle plate 13. A liquid cavity 14 is formed between the distributing plate 12 and the baffle plate 13. The distributing plate is provided with a flow guide tube 16, and the baffle plate is provided with a spray cup 17 corresponding to the flow guide tube 16. The lower part of the cylinder is provided with a circulating tank 18, the lower wall of the cylinder is provided with a through hole communicated with the inner cavity and the circulating tank, and the lower part of the cylinder is provided with a liquid outlet slot. Dusty fume enters the spray cup with absorbing solution for spraying after entering from a fume inlet, so that the mixing and contact effects of fume and absorbing solution can be enhanced, and the absorbing solution can fully absorb and collect powdery dust and harmful substances. The dust removing efficiency reaches to 95%, and the desulfurizing efficiency reaches to 60%.
Description
The utility model is used for the boiler fume desulfurizing and dedusting purified treatment.
The desulfurization and dedusting of boiler smoke often adopts wet purifying decice, absorption liquid is mixed contacting with flue gas, makes flue gas and absorption liquid carry out gas-liquid mass transfer then, absorption liquid and dust are separated from flue gas, and flue gas is purified.
Fig. 1 is the cutaway view of existing boiler fume desulfurizing and dedusting device.This device has main tube 1, secondary tube 2, and the top communicates, and main tube upper outside has tank 3, and inlet opening 4 is arranged on the barrel at this place, and water enters main tube by this place and forms the flushing moisture film, connects feed tube 6 on the Venturi tube 5.Ash-laden gas mixes through Venturi tube and with absorption liquid in entering this pipe, absorption liquid promptly absorbs, captures dust in flue gas and harmful substance, tangentially enter main tube by main tube bottom import 7 then, rotation is risen, absorption liquid and dust are separated with flue gas, the moisture film that is formed by main tube top takes it to main tube bottom again, gets rid of through exporting 8.The flue gas of purified treatment enters secondary tube by the top, carries out second dehydration, discharges through exporting 9 again.This device has dust removing effects preferably, but because absorption liquid contacts with flue gas in Venturi tube, incorporation time is short, desulfuration efficiency is lower, is generally about 40%.
The purpose of this utility model provides a kind of boiler fume desulfurizing and dedusting device, and this deduster efficiency of dust collection height also has desulfurized effect preferably.
The technical solution of the utility model is referring to Fig. 2.The utility model has cylindrical shell 10, and into mouth 11 is arranged at the cylindrical shell top, and distribution plate 12 and dividing plate 13 are arranged at cylinder lumen top, is sap cavity 14 between distribution plate and the dividing plate, and this sap cavity connects feed tube 15; Mozzle 16 is arranged on the distribution plate 12, and dividing plate 13 is provided with and mozzle 16 corresponding spray cups 17; Spray cup 17 communicates with sap cavity; There is circulating tanks 18 in the cylindrical shell 10 bottoms outsides, and through hole 20 is arranged on the lower cylinder wall, this through hole connected ring chute and cylinder lumen, and liquid outlet groove 19 is arranged at the cylindrical shell bottom, and this liquid outlet groove communicates with cylinder lumen and circulating tanks, circulating tanks 18 mouth 21 that runs in.The desulfurization and dedusting process is, ash-laden gas advances mouth by the top and enters in the cylindrical shell, mozzle 16 on distribution plate enters the spray cup, and simultaneously, the absorption liquid in the sap cavity also enters the spray cup, because fan pressure effect, flue gas and absorption liquid are together sprayed downwards by spray cup spout, and flue gas is fully mixed with absorption liquid, carry out sufficient gas-liquid mass transfer, make absorption liquid absorb, capture dust in flue gas efficiently and absorb sulfur in smoke effectively, reach the purpose of desulfurization and dedusting.Flue gas behind contact in cylindrical shell, the mixing certain hour enters circulating tanks again, behind eddy flow, absorption liquid and dust separation is come, and flue gas after being purified is discharged by exhaust opening, and the dust-containing liquid matter in cylindrical shell bottom and the circulating tanks is discharged by liquid outlet groove 19.
Characteristics of the present utility model are that by the spray cup is set, ash-laden gas and absorption liquid are together sprayed by the spray cup, can improve widely flue gas and absorption liquid mixing, contact effect, make absorption liquid absorb, capture dust and harmful substance effectively, efficiency of dust collection is about 95%, and desulfuration efficiency reaches about 60%.Simple in structure, resistance is lower.
Description of drawings, Fig. 2 is a technical solution of the utility model structure cutaway view, Fig. 3 is the A-A view of Fig. 2, have among the figure: cylindrical shell 10, advance mouth 11, distribution plate 12, dividing plate 13, sap cavity 14, feed tube 15, mozzle 16, spray cup 17, circulating tanks 18, liquid outlet groove 19, through hole 20, exhaust opening 21.
Embodiment, structure is referring to Fig. 2, Fig. 3.The cylindrical shell top is that metal material is made, spray cup ceramic making, and all the other are with numb work made of stones.Through hole 20 on the cylindrical shell lower part wall and cylinder lumen are for tangentially communicating, exhaust opening tangentially communicates with circulating tanks, 1.08 meters of cylinder internal diameters, if 25 in spray cup, 80 millimeters of every spray cup nozzle diameters, 30 meters of wind speed per seconds absorb per hour 30 cubic metres of liquid measures, spray about 450 handkerchiefs of cup resistance, can be used for the flue gas desulfurization and dedusting of 4 tons of boilers.During operation, the liquid matter in cylindrical shell bottom and the liquid outlet groove plays the sealed cylinder inner chamber.
