Description
Technical field
This utility model belongs to coal power field, specifically, is the booster fan of power plant band bypass.
Background technology
In order to realize the strict supervision to coal-fired power plant's desulfurization equipment, the national environmental protection Room has issued each department Thermal Power Enterprises will be progressively
Transforming the notice of built desulfurization equipment, environment-development 2012 No. 27 literary composition in osmanthus, Guangxi District " sets about strengthening fossil power plant desulfurization
Execute operation and desulfurization electricity price management notice " in also require that more than 300,000 kilowatts pure generating fired power generating unit of unit will be before the end of the year 2013
Complete transformation.
Desulphurization system and boiler are fully formed haplotype train, and therefore the operational reliability of whole unit can be substantially reduced.
Main cause have following some: first, desulfurizer is connected with main frame, it is necessary to synchronize start and stop, if booster fan stop jumping, cigarette
Gas leads to the passage of chimney and is almost cut off, inevitable significantly load shedding or the shutdown of unit；Secondly, (example when boiler side breaks down
Such as air preheater stop jumping), high-temperature flue gas does not bypass can be walked, and will be directed into absorption tower, and in certainly will causing tower, facility is badly damaged very
Scrap to absorption tower, cause tremendous economic to lose；It addition, the flue gas that during start and stop, furnace fuel oil produces can pollute serosity,
How to replace and process the working medium being polluted by the oil in shutdown process, be also the problem needing to solve.Therefore, it is necessary to have careful, thin
Cause, related system is transformed by feasible scheme.
