Description
Technical field
The present invention relates to gaseous contamination processing units, are exactly a kind of biomass flue gas dust-removal and desulfurizing denitrating systems.
Background technology
Biomass boiler is a kind of using biomass energy as the boiler of fuel, and fuel biomass is a kind of renewable
Using the energy, bio-energy pellet fuel is to utilize stalk, rice stalk, yule logs, sawdust, peanut shell, melon seed cases, beet pulp, tree
The crops of all wastes such as skin squeeze the techniques such as drying through being pulverized and mixed, are eventually fabricated granular fuel.In its original of China
Material is widely distributed, and processing technology is advanced, and biomass energy particle material is famous with green coal, is a kind of clear energy sources, raw simultaneously
The price of substance boiler is relatively low and fuel cost is also low, is the novel energy of both economical environmental protection.But biomass is in combustion process
In, it still will produce a large amount of dust, SO2And NOx pollutants, simultaneously because its dust, SO2, NOx and temperature problem so that
Biomass boiler dedusting, desulphurization and denitration are difficult, and cost is very high, and the mode of the processing of gas cleaning at present mainly has:
Flue gas ash removal process:Due to biomass boiler, its water-in-fuel rate is higher, and ash content has very high viscosity, therefore
It is difficult to handle flue gas using common bag filter, technique more mature at present is removed using cyclone dust removal+cloth bag
The process of dirt removes a large amount of lightweight dust first with cyclone dust removal, while taking away the moisture in flue gas, recycles filtration velocity
Lower bag filter carries out gas cleaning processing.To reach the qualified discharge of dust.
Flue gas desulfurization course:Since biomass boiler its primary combustion medium is biomass, sulfur content in flue gas
It changes greatly, and overall sulfur content is relatively low, the SO in general flue gas2In 100~400mg/Nm3Between, content is low, at present state
The biomass boiler of interior installation flue gas desulfurization is less, and more mature technique is to use limewash method flue gas desulfurization, utilizes lime
Alkalinity, by the SO in flue gas2Purification generates by-product gypsum.Due to SO in flue gas2Concentration is very low, thus overall investment compared with
It is high.
Denitrating flue gas process:Due to biomass boiler, its dust viscosity is higher, and contains the alkalinous metals such as Na, K in dust,
It is affected to denitrating catalyst, and after dedusting, flue-gas temperature is low, does not have the temperature range for building SCR denitration system, because
Domestic biomass boiler denitrating flue gas process generally uses SNCR to carry out gas cleaning at present for this, but SNCR systems its denitration effect
Rate is low, and the escaping of ammonia is high, be easy to cause secondary pollution.And by dedusting after, then carry out flue gas heating SCR denitration if the energy disappear
Consumption is too high, and economy is very poor, therefore biomass boiler denitrating flue gas process is currently without good solution.
Invention content
The technical problem to be solved in the present invention is to provide a kind of biomass flue gas dust-removal and desulfurizing denitrating system, the system flue gases
