Abstract
The utility model provides a dust removal desulphurization purification apparatus for the smoke gas of a boiler, and belongs to a dust removal desulphurization purification device for smoke gas discharged from industry and families. The utility model is characterized in that a smoke gas inlet is arranged on the upper part of a main tower, and the inlet extends into the upper part along the tangent direction. A purified liquid cylinder body is also arranged on the main tower, the purified liquid cylinder body comprises at least one venturi, a purification inlet pipe, a liquid discharging pipe, a level gauge and a ball float valve, and a vibrating motor and a conveyor are also arranged on the lower part of the main tower. The utility model can be used as a purification device for removing and desulfurizing smoke gas discharged by industrial and civil boilers; the utility model can be widely used for the purification of boilers used in restaurants, factories and mines, organs, schools, etc., and has the advantage of environmental protection.
Description
The utility model provides a kind of boiler smoke gas dust-removal and desulfurizing purifier, relates to industry and civil boiler dust dust-removal and desulfurizing cleaning equipment.
Existing industry and civil boiler (fire coal, fuel oil) high-temperature smoke gas is after wet dedusting desulfurization is handled, and desulfuration efficiency reaches 80-85%, and about 50 ℃ of discharge temperature does not reach 70 ℃ discharge standard.Because boiler furnace is little negative pressure operation, general industry and civil boiler heat loss due to exhaust gas size directly influence the completing combustion of coal-fired (oil), and increase the loss of coal-fired (oil), increase the consumption of energy.Low excessively as exhaust temperature, also can be directed at sour corrosion, the lifting of influence height.How to improve boiler smoke qi exhaustion sulphur efficiency, improving the exhaust emissions temperature is the technical problem of being badly in need of solution behind current fire coal (oil) the boiler smoke gas dust-removal and desulfurizing.
The purpose of this utility model is exactly for the efficient that improves boiler smoke gas dust-removal and desulfurizing and exhaust emissions temperature and a kind of boiler smoke gas dust-removal and desulfurizing purifier that designs.
The utlity model has king-tower and attached tower, king-tower and attached tower are by the flange bolt sealed attachment, and described king-tower I is provided with dust import a, and this dust import a is that tangent line enters; Described king-tower I also is provided with scavenging solution cylindrical shell m, and this scavenging solution cylindrical shell m comprises at least one Venturi tube 1, purified gas inlet tube 7, discharging tube 8, liquid level gauge 9 and float-controlled valve 10.Discharge elbow 5 and the tube connector 6 that separates barrier 4 and connect attached tower II is housed at the top of king-tower I.Be provided with vibrating motor 2 and conveying worm 3 in the bottom of king-tower I.The lower end of described attached tower II is equipped with residual cake valve 11.Described Venturi tube 1 can have a plurality of.
The utility model adopts master, attached tower and a plurality of Venturi tube can make full use of the temperature effect of high-temperature smoke gas, and the Venturi tube circulation mixes purification and exhaust effect, and the high-temperature tail gas after the purification discharges can be stabilized in 70 ℃.The thermal property of boiler little negative pressure operation can the change greatly boiler increases the power of tail gas and buoyancy, is beneficial to atmospheric turbulance diffusion dilution and self-cleaning; Its efficiency of dust collection can reach 99%, and desulfuration efficiency can reach 90% and improve the environment protection standard rate.
Now described in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural plan figure.
Fig. 2 is along the vertical perspective view of A-A section among Fig. 1.
As shown in the figure, high temperature (500-600 ℃) dust of discharging from boiler (contains grit and SO
2), through the dust import a on king-tower I top eddy flow, flow to Venturi tube 1 downwards, flow velocity increases when dust enters collapsible tube, enters trunnion 12 speed and reaches maximum, forms negative pressure at trunnion 12 places, some apertures are arranged at the top outside the trunnion 12 at Venturi tube 1 place, make to purify emulsion by entering Venturi tube 1 interior circulation outward automatically, diffusion is wetting rapidly to make grit, and cohesion decline is deposited in king-tower I bottom and discharges through conveying worm 3.SO in the high-temperature smoke
2H is combined in the water vapour absorption that pernicious gas also is cleaned in cyclic process in the emulsion
2SO
4Thimerosal, its dedusting particle diameter can reach 0.05-100m.Purified gas rises through purified gas outlet b backhaul behind the high-temperature smoke heat of the intermediate conduit absorption portion on king-tower I top, enter attached tower II through separation barrier 4 by discharge elbow 5 and tube connector 6 and carry out double purification, enter atmosphere through the air-introduced machine chimney again, so can improve exhaust temperature and tail gas lifting temperature.
When the concentration that purifies emulsion reaches pH value 9-12, can reduce the surface tension of scavenging solution and the interfacial tension between the flue dust, make that wettability and emulsifiability improve between dust grit and the scavenging solution, accelerate the purification on solution-air surface and gas-solid surface and assembled, thereby reached the effect of desulfurization and dedusting.When the pH value that purifies emulsion＜9, float-controlled valve 10 is in time opened automatically, replenishes liquid level and also keeps scavenging solution concentration that pH value is stabilized between the 9-12.
Also be provided with 2 vibrating motors 2 in the bottom of king-tower I, the control Timing vibration prevents dirt slag caking, makes the dirt slag can pass through conveying worm 3 smooth and easy discharges.
