Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refering to shown in Fig. 1, the energy-saving environment protection steam boiler that the embodiment of the present invention provides, mainly include furnace body and be positioned at the pot body above furnace body.Furnace body is provided with combustor 13；Being provided with drum 1 in pot body, in drum 1, lateral arrangement has top smoke pipe 2, middle part smoke pipe 3 and bottom smoke pipe 4 from top to bottom.Top smoke pipe 2, middle part smoke pipe 3 and bottom smoke pipe 4 are made up of some independent monomer smoke pipes respectively, then can strengthen heat exchange area, improve thermal conversion efficiency.Being provided with the second smoke box 5 at pot outer body, the pot outer body on the second smoke box 5 opposite is provided with the first smoke box 6 and is positioned at the 3rd smoke box 7 above the first smoke box 5；First smoke box 5 is connected with the second smoke box 5 by bottom smoke pipe 4, and the second smoke box 5 is connected with the 3rd smoke box 7 by middle part smoke pipe 3, and the 3rd smoke box 7 is communicated to outlet flue 8 by top smoke pipe 2, and outlet flue 8 is communicated to chimney 14；Second smoke box 5 and chimney 14 are provided with photo catalysis reactor 9.It is provided with dirt pocket 10 in first smoke box 6 and is positioned at the photo catalysis reactor 9 above dirt pocket 10.Dirt pocket 10 is connected with combustor 13 by first row smoke pipe 11, is connected with the light-catalyzed reaction reactor 9 being located in the first smoke box 6 by second row smoke pipe 12；The light-catalyzed reaction reactor 9 being located in the second smoke box 5 is connected with bottom smoke pipe 4 by the 3rd smoke exhaust pipe 15.The photo catalysis reactor 9 being arranged in the first smoke box 6 is connected with second row smoke pipe 12 by Flange joint, and the photo catalysis reactor 9 being arranged in the second smoke box 5 is connected by Flange joint and the 3rd smoke exhaust pipe 15；Dirt pocket 10 is connected with first row smoke pipe 11 and second row smoke pipe 12 respectively by Flange joint.Dirt pocket 10 bottom has a dust-storage chamber 101, can store the dust in flue gas.Photo catalysis reactor 9 is made up of, as shown in Figure 2 filter 91, photocatalyst material net 92, photocatalysis light source 93 and photocatalyst material net 92 from bottom to top.Photocatalyst material net 92 is nano-TiO2Absorbent charcoal composite material net, photocatalyst is nano-TiO2, photocatalysis light source 93 is LED light source, can the most effectively work.
Fuel burns in combustor 13, produces high heat flue gas.With dust, SO in flue gas2And NOxDeng pollutant.During boiler operatiopn, the flue gas in combustor 13 first passes around first row smoke pipe 11 and enters dirt pocket 10.Dirt pocket 10 in innermost end not outlet, flue gas can only after arriving innermost end reverse reflex, now the relatively heavy substance such as the dust in flue gas can be stayed in dirt pocket, and is stored in dust-storage chamber 101.First row smoke pipe 11 two ends not level, high near combustor 13 one end, low near dirt pocket 10 one end, this being designed to does not interfere with each other so that the flue gas of turnover dirt pocket 10, the flue gas with more dust is conducive to enter dirt pocket 10 in first row smoke pipe 11 bottom, the flue gas of less dust leaves dirt pocket 10 from top, and improves flue gas circulating rate.Dirt pocket 10 can be opened, and can open dirt pocket 10 as required to materials such as the dust of clearing up in dirt pocket 10 and dust-storage chamber 101.Flue gas is entered by second row smoke pipe 12 the most afterwards from dirt pocket 10 and is located at the photo catalysis reactor 9 the first smoke box 6.Having filter 91 in photo catalysis reactor 9, flue gas first passes around filter 91, and filter 91 can stop the polluters such as the dust in partial fume to enter the pollutant such as photo catalysis reactor 9, the further dust removed in flue gas.Nano-TiO2Photocatalyst can play the effect of catalyst under LED light source irradiates, and flue gas enters photo catalysis reactor 9, pollutant (the predominantly SO when photocatalyst material net 92, in flue gas2And NOx) self can carry out chemical reaction, ultimately generate boiler inner wall harmless, the SO that environmental pollution is less3And HNO3.By increasing photo catalysis reactor 9 in the first smoke box 6, the effect such as dedusting, desulfurization removing nitric i.e. can be played.Flue gas enters the first smoke box 6 the most afterwards from the photo catalysis reactor 9 being located at the first smoke box 6, is then passed through bottom smoke pipe 4 and the 3rd smoke exhaust pipe 15 enters and is located at the photo catalysis reactor 9 in the second smoke box 5, again carry out dedusting and desulfurization removing nitric.Subsequently flue gas is from the photo catalysis reactor 9 being located at the second smoke box 5 out, enters the second smoke box 5, then sequentially passes through middle part smoke pipe the 3, the 3rd smoke box 7, top smoke pipe 2, outlet flue 8, subsequently into chimney 14, discharges boiler finally by chimney 14.In chimney 14, it is provided with photo catalysis reactor 9, boiler can be discharged at flue gas and take a step forward the dust removed in flue gas, SO2And NOxDeng pollutant.Photo catalysis reactor 9 is in the same size with chimney 14, thus can play saving space and the effect of material.First smoke box 6 is connected with the second smoke box 5 be connected with pot body by screw, nut.This connected mode is convenient to dirt pocket 10, dust-storage chamber 101 and the cleaning of photo catalysis reactor 9, keeps in repair and change.
Through flue gas being carried out chalk dust removing, desulfurization removing nitric at dirt pocket 10 and photo catalysis reactor 9, in the flue gas left, the pollutant such as dust are less, boiler inner tubal wall will not be corroded, also smoke pipe etc. will not be blocked, it is prone to the working service of boiler, use cost can be reduced, and reach the purpose of environmental protection and saving.Described dirt pocket 10 and photo catalysis reactor 9 are arranged in boiler, and compared with dedusting outside being independently disposed to boiler with other, nitrogen and desulfurization device, energy-saving environment protection steam boiler disclosed in the present embodiment has that occupation of land is little, easy of integration and the advantage such as easy care.
The above; being only the detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; the change that can readily occur in or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with described scope of the claims.
