Description
Technical field
The utility model relates to field of Environment Protection, especially relates to a kind of limestone-gypsum desulphurization system.
Background technology
Sulfur dioxide and nitrogen oxide affect larger gaseous contaminant in atmosphere pollution, has high risks to human body, environment and the ecosystem, along with the increasingly stringent of environmental requirement, and NO
xand SO
2the problem of discharge more and more receives publicity.Sulfur dioxide and nitrogen oxide mainly stem from the combustion process of the fossil fuel such as coal, oil, and the roasting of ore, the fume emission of smelting process, wherein various burning boiler particularly power plant boiler smoke evacuation there is the features such as concentration is low, exhaust gas volumn is large, floating dust is many and be difficult to administer.In conventional art, desulfurization and denitration are normally separately carried out by discharge sulfur dioxide in flue gas and purification of nitrogen oxides technology, which results in the defects such as the complexity of discharging flue gas purification system is huge, initial outlay is large, operating cost is high, seriously constrain the actual enforcement of discharge flue gas desulfurization and denitrification.Flue gas desulfurization technique is mainly based on Gypsum Wet, rotating spraying semidry method, in-furnace calcium spraying afterbody humidification activation, sea water desulfuration, electron-beam desulfurization, flue gas circulating fluidized bed desulfurization etc., wherein Wet Limestone method is the tail flue gas desulfur technology be most widely used in the world now, its subject matter is that the solubility of absorbent (lime or lime stone) is little, utilization rate is low, and waste residue amount is large; Gas denitrifying technology mainly contains SCR technology (SCR), SNCR technology (SNCR), electronic beam method, impulse electric corona method, complex compound absorption process and urea absorptive method etc., gas denitrifying technology mainly SCR technology, SNCR technology and SNCR/SCR combination technique comparatively ripe in current operation, but there is initial investment costly in SCR method, operating temperature range is narrow, and there is NH_3 leakage, can N be generated
2o, and the shortcoming such as catalyst easy in inactivation; And SNCR denitration efficiency is lower, and NH_3 leakage is many, causes secondary pollution.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of compact conformation, and floor space is little, the limestone-gypsum desulphurization system that treatment effeciency is high, and the technical scheme of employing is as follows:
A kind of limestone-gypsum desulphurization system, comprise desulfurizing tower, circulatory pool, gypsum thinning tank and gypsum extruder, desulfurizing tower arranges blast pipe from top to down, demist isolated gate, shower, perforated trays, air inlet pipe, circulation drain pipe, storage slag bath and first row cinder notch, circulation drain pipe connects circulatory pool, circulatory pool has second row cinder notch, circulatory pool connects shower by circulating pump, described gypsum thinning tank comprises stirring motor, stirring motor connects paddle, gypsum thinning tank bottom is provided with the 3rd slag notch, gypsum thinning tank top is provided with pulp-inlet pipe and secondary water inlet pipe, gypsum thinning tank connects circulatory pool by pipeline, pulp-inlet pipe connects gypsum extruser, gypsum extruser is provided with a water inlet pipe, helical axis, lime bucket and drive unit.
Further, described perforated trays and shower are multilayer and arrange, and described gypsum extruser is provided with washing outlet.
Further, described isolation demist grid are reverse V-shaped, and described drive unit is AC induction motor, and described circulating pump is Centrifugal Pump.
Adopt the device of above-mentioned double alkali method desulfurizing technology, compact conformation, floor space is little, and exhaust treatment efficiency is high.
