The technical solution used in the present invention is as follows:
A kind of high-efficiency energy-saving desulfurizing deduster system, comprise boiler, deduster, air-introduced machine, the exhanst gas outlet of boiler connects the air inlet of deduster, the gas outlet of deduster connects the air inlet of air-introduced machine, it is characterized in that described fan out draft connects the upper end of spray chamber, the lower end of spray chamber is installed on the devulcanizer body, be provided with the central dividing plate that the devulcanizer body is separated into two bins in the devulcanizer body, described spray chamber communicates with one of them bin of devulcanizer body, on the devulcanizer body, also be provided with the dewatering station that communicates with another bin, the outlet of dewatering station is connected to chimney, concrete earth foundation tube is installed in described devulcanizer body lower end, is placed with doctor solution in the concrete foundation tube.
The bottom of described concrete foundation tube is provided with swash plate.
Bin sidewall in the coupled logical devulcanizer main body in described spray chamber below is provided with the secondary spraying mouth.
The lower ending opening of described concrete foundation tube bottom swash plate is connected with the circulatory pool of concrete foundation tube outside.
Be provided with the baffle device for water that four layers of angle bar form in the described dewatering station.
Beneficial effect of the present invention has:
Native system integrates spray, whirlwind, the dust-removal and desulfurizing process such as impacts, washes away, efficiency of dust collection＞98%, desulfuration efficiency＞90%, and not high to the dust contained flue gas concentration requirement that enters devulcanizer, this desulphurization system has good dust removing effects, is that other desulphurization system is incomparable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1, the exhanst gas outlet of boiler 1 of the present invention connects the air inlet of deduster 2, and the gas outlet of deduster 2 connects the air inlet of air-introduced machine 3, and described air-introduced machine 3 air outlets connect the upper end of spray chamber 4, and the lower end of spray chamber 4 is installed on the devulcanizer body 5.Be provided with central dividing plate 6 in the devulcanizer body 5, central dividing plate 6 is separated into two bins with devulcanizer body 5, one of them bin communicates and communicates with spray chamber 4, and another bin communicates with dewatering station 7 on being installed in devulcanizer body 5, and the outlet of dewatering station 7 is connected to chimney 8.Be provided with the baffle device for water 13 that four layers of angle bar form in the dewatering station 7.
Concrete earth foundation tube 9 is installed in devulcanizer body of the present invention 5 lower ends, and the bottom of concrete foundation tube 9 is provided with swash plate 11, and the lower ending opening of swash plate 11 is connected with the circulatory pool 10 of concrete foundation tube 9 outsides.Be placed with doctor solution in the concrete foundation tube 9.
Bin sidewall in the coupled logical devulcanizer main body 5 in spray chamber of the present invention 4 belows is provided with secondary spraying mouth 12.Deduster 2 is that sack cleaner or other type deduster all can.
The course of work of the present invention is as follows:
The sulfurous gas that comes out from boiler 1 enters air-introduced machine 3 after deduster 2 dedustings, enter this desulfurizer through air-introduced machine 3.The first step enters spray chamber 4, and the doctor solution of spray is fully mixed in flue gas and the spray chamber 4 enters desulfurization tube body 5 after contacting.Mixed flue gas from top to bottom in desulfurization tube body 5 central dividing plate 6 lower ends enter the bin of desulfurization tube body 5, after dehydration, drain into chimney 8 to dewatering station 7 from bottom to top from this side bin again, enter atmosphere from chimney 8.
Sulfur-containing smoke gas of the present invention and doctor solution directly rush at mozzle elbow, spray chamber 4 lower end after contact, mixes for the first time in the water distribution system of spray chamber 4, make flue gas and doctor solution that secondary abundant mixing and haptoreaction arranged by collision.Enter in the devulcanizer body 5 by mozzle guiding and to wash away to central dividing plate 6 again, make flue gas and doctor solution that fully mixed and haptoreaction for the third time, the just progressively separation in dropping process of doctor solution and desulfurization product arranged.The product of acid-base neutralization and dust in flue gas, impurity, water droplet directly fall under gravity, action of centrifugal force in the concrete foundation tube 9 of devulcanizer body 5 bottoms, after crossing central dividing plate 6, band shredded tobacco for water pipes cyclostrophic moves from bottom to top, flue gas washes away once more through the circulation solution of central dividing plate 6 landings again in this process, clean flue gas moves up to and effluxes after dewatering station 7 finishes further dehydration, and this process is that desulfurization, dedusting, dehydration are carried out synchronously, progressively finished.Devulcanizer body of the present invention 5 lower ends are uncovered to fuse with concrete foundation tube 9, and concrete foundation tube 9 links to each other with circulatory pool 10, and the liquid level in the concrete foundation tube 9 can be regulated according to the resistance and the regulation effect of flue gas.When the liquid level rising, liquid level and central dividing plate 6 lower ends distance diminishes in the concrete foundation tube 9, and the contact-making surface of flue gas and liquid level promptly increases, and makes flue gas and doctor solution that haptoreaction arranged one time.Effect by this colliding repeatedly repeatedly, contact and reaction desulfuration, dedusting improves greatly.Because swash plate 11 lower ending openings and circulatory pool 10 intercommunications of concrete foundation tube 9, be circulatory pool 11 sludge pipes, one end and the 9 lower ending opening place intercommunications of concrete foundation tube, handle the mud (dust in the flue gas falls into doctor solution and forms mud) collected through concrete foundation tube 9 device and efflux by sludge pump to Ji Nikou along swash plate 11 landings.
Baffle device for water 13 in the dewatering station 7 of the present invention has four layers of angle bar to divide two groups of arrangements, and angle bar one end is welded in cylindrical shell, and the other end surpluss 30 to updip
ODock with the angle bar of another identical set at the angle, last layer angle bar and following one deck are apart from 150mm, stagger in the position, two layers is one group totally two groups, collide with the last layer watertight layer again through rolling in the uphill process that looses in the wet flue gas uphill process with after following one deck collision, captured by the dash angle bar after fine droplet constantly condenses through repeatedly colliding, along angle bar to the barrel landing.It is big that baffle device for water 13 in the dewatering station 7 have angle bar layer intensity, and anti-filling rinsed, knocked, and be convenient to cleaning and safeguard, and characteristics such as high temperature resistant.
The undeclared part of other that the present invention relates to is same as the prior art.
