Detailed description of the invention
Coal-burning boiler ultrafine dust of the present invention catches, desulfurization and denitrification integral equipment comprises dedusting piece housing 1, dedusting piece housing 1 one end arranges air inlet 2, in air inlet 2, shower 21 is installed, shower 21 is arranged atomizer 22, dedusting piece housing 1 other end is communicated with the inlet end of negative pressure channel 3, in negative pressure channel 3, negative-pressure air fan 16 is installed, axis 4 is installed in the inner axial centre position of dedusting piece housing 1, axis 4 is connected with dedusting piece housing 1 by bracing strut, axis 4 is installed at least one first dust extractor 6 and at least one second dust extractor 7, first dust extractor 6 and the interlaced setting of the second dust extractor 7, first dust extractor 6 comprises the first Dust collecting net support 8, first Dust collecting net support 8 is connected with axis 4 by the first rotating shaft holder 9, first Dust collecting net support 8 is installed the first Dust collecting net 10, first Dust collecting net support 8 periphery arranges the first impeller 11, second dust extractor 7 comprises the second impeller 12, second impeller 12 is connected with axis 4 by the second rotating shaft holder 13, second impeller 12 periphery arranges the second Dust collecting net support 14, second Dust collecting net support 14 is installed the second Dust collecting net 15, dedusting piece housing 1 sidewall periphery arranges outer sleeve 17, between outer sleeve 17 inwall and dedusting piece housing 1 outer wall, collect cavity 18 is set, dedusting piece housing 1 sidewall offers multiple through hole 19, through hole 19 two ends are communicated with collect cavity 18 with dedusting piece housing 1 inside respectively, dedusting piece housing 1 installs first gear water ring 20 near the inwall border, one end of negative-pressure air fan 16.When equipment is installed, air inlet 2 docks with the exhaust outlet of boiler 42, and the outlet side of negative pressure channel 3 is communicated with chimney 43.During use, shower 21 passes into limewash, limewash sprays in air inlet 2 after atomizer 22 is atomized, the flue gas that boiler 42 is discharged flows to the chimney 43 of negative pressure channel 3 outlet side under the effect of negative-pressure air fan 16 from air inlet 2, when airflow passes first dust extractor 6 that negative-pressure air fan 16 produces and the second dust extractor 7, first impeller 11 and the second impeller 12 drive the first Dust collecting net 10 and the second Dust collecting net 15 axis 4 of having mercy on to rotate respectively under the effect of air-flow, flue gas contacts with the limewash of atomization in air inlet 2, dust in flue gas, the droplet that sulfur dioxide and nitrogen oxide and limewash are formed collides, dust-laden drop is formed after gummed, when dust-laden drop passes through the first dust extractor 6 and the second dust extractor 7 with air-flow, the network structure of the first Dust collecting net 10 and the second Dust collecting net 15 catches dust-laden drop, dust-laden drop is attached to after on Dust collecting net, under rotating at Dust collecting net the centrifugal action produced, dust-laden drop converges formation liquid and moves outside Dust collecting net gradually, final disengaging Dust collecting net is also thrown toward dedusting piece housing 1 madial wall, when dust-containing liquid drops in and Dust collecting net adheres to, the water surface tension of liquid self can form moisture film in the subregion of Dust collecting net, moisture film forms bubble gradually and then breaks under airflow function, better seizure effect can be played to the dust-laden drop in air-flow before water break, the first Dust collecting net 10 be crisscross arranged and the second Dust collecting net 15 can cover the inner whole gas channel of dedusting piece housing 1, because Dust collecting net self constantly rotates, network structure and the online moisture film formed of Dust collecting net can play omnibearing efficient seizure to dust-laden drop, in addition, the blade of the first impeller 11 and the second impeller 12 also can play seizure effect to part dust-laden drop, and dust-laden drop is got rid of to dedusting piece housing 1 madial wall, dust-laden drop can enter collect cavity 18 centralized collection by the through hole 19 that dedusting piece housing 1 sidewall is offered.The first dust extractor 6 that axis 4 is installed all is connected with axis by respective rotating shaft holder with the second dust extractor 7, on the basis of this structure, each dust extractor can be realized rotate with mutually different speed under airflow function by arranging different impeller blade angles and leaf position, the liquid volume that the Dust collecting net of the multiple dust extractors in rotating shaft 4 is adhered to and liquid realize differentiation to the translational speed outside Dust collecting net, thus enable the present invention guarantee the capturing efficiency of dust-laden drop when flue gas flow rate constantly changes.The content of dust, sulfur dioxide and nitrogen oxide in the flue gas after the present invention can make process meets the requirement of relevant national standard, and equipment own vol is little, be conducive to enterprise and make full use of limited plant area's area, commutation is not needed in fume treatment process, flow resistance is little, do not need to be equipped with large-scale air inducing equipment, cost taken by themselves, equipment energy consumption, later maintenance difficulty and maintenance cost are all significantly lower than existing fire coal boiler fume treatment facility.
First Dust collecting net support 8 of the present invention and the second Dust collecting net support 14 are all for playing a supportive role to Dust collecting net, for realizing this effect, various structures can be adopted, such as cross section is adopted to be columniform support ring, the structures such as support bar, its preferred structure is: described first Dust collecting net support 8 and the second Dust collecting net support 14 include interior annular backup pad 23 and Outer annular support plate 24, support bar 25 by radial setting between interior annular backup pad 23 and Outer annular support plate 24 connects, first Dust collecting net 10 or the second Dust collecting net 15 are arranged between interior annular backup pad 23 and Outer annular support plate 24, multiple water conservancy diversion through hole 26 is offered in Outer annular support plate 24 border, the interior annular backup pad 23 of the first Dust collecting net support 8 is connected with the first rotating shaft holder 9, the interior annular backup pad 23 of the second Dust collecting net support 14 is connected with the second impeller 12.This structure has not yielding, that windage is minimum advantage.
The present invention is in order to regulate fume treatment efficiency at any time, the first support 5 and the second support 28 can be comprised at described bracing strut, first support 5 is installed the first axle sleeve 29, second support 28 is installed the second axle sleeve 30, axis 4 is arranged in the first axle sleeve 29 and the second axle sleeve 30, axis 4 can moving axially along the first axle sleeve 29 and the second axle sleeve 30, axis 4 one end is connected with the piston rod of hydraulic cylinder 27, hydraulic cylinder 27 is arranged on the first support 5, axis 4 is installed bulge loop 31, first dust extractor 6 and the second dust extractor 7 are installed between bulge loop 31 and the second support 28, the rotating shaft holder of the first dust extractor 6 and the second dust extractor 7 all can move along axis 4 length direction, adjacent rotating shaft holder and equal mounting spring 32 between rotating shaft holder and the second support 28.When pollutant load in the flue gas of smoke stack emission exceeds relevant criterion, by hydraulic cylinder 27 direction from piston rod to the second support 28 promote axis 4, bulge loop 31 on axis 4 forms extruding to adjacent rotating shaft holder, Compress Spring 32 simultaneously, distance between each rotating shaft holder is reduced, and each dust extractor is close to each other, improves the density of Dust collecting net in unit space, strengthen fume treatment efficiency, the pollutant load in flue gas is reduced rapidly.This structure can realize regulating the convenient of dust extractor spacing, does not need to arrange accurate governor motion, large and not easily break down under the working environment of humidity in dustiness, long service life.
