Detailed description of the invention
For making features described above of the present utility model and advantage to become apparent, special embodiment below, and coordinate institute's accompanying drawing to make in detail
Carefully it is described as follows.
The present embodiment provides a kind of new desulfurization fluidized wind system, uses in 2 × 600MW unit minimum discharge desulphurization system,
Power plant instrument is utilized to provide fluidized wind by compressed-air actuated allowance to limestone powder bin.According to calculating, each limestone powder bin needs stream
Wind-transformation amount is 1.7Nm3/ min, pressure head is 0.1MPA.Compressed air for instrument mother's pipe 3 has connect the nothing that a caliber is DN40
Seam steel pipe (material is 304), as admission line 2, accesses 1 2m3Compressed air for instrument tank 1, the most again by giving vent to anger
Pipeline 4 is connected to limestone powder bin fluidized plate 7.Due to power plant's compressed air for instrument sometimes because running bad causing except water exsiccator
Air band water, arranges a fluidized wind electric heater 10 as standby on bypass line 8, then this pipeline in parallel on outlet pipe 4
With, its power is 30kW.
Compressed air for instrument tank 1 top and bottom center connect the pipeline having band valve, the regulation of gas flow or connection in tank
Other devices, it is additionally provided with a Pressure gauge (not shown), for detecting the gas pressure in tank.On outlet pipe 4 with
The part of bypass duct 8 parallel connection is provided with an electrodynamic valve 5, also is provided with electrodynamic valve 9 on bypass duct 8.In fluidized plate 7 front
It is additionally provided with thermometer 6 on outlet pipe 4, enters the gas temperature of fluidized plate 7 with real-time detection.
When usually using, electrodynamic valve 5 is in open mode, and electrodynamic valve 9 is closed, and gas is sent by outlet pipe 4
Enter fluidized plate 7, so that limestone powder bin to be ventilated.When gas temperature is low, it is shut off electrodynamic valve 5, opens electrodynamic valve 9,
Starting fluidized wind electric heater 10, gas is fluidized wind-powered electricity generation heater 10 by bypass duct 8 and heats, and is re-fed into fluidized plate 7
In, thus avoid the generation that agstone bonds.
The beneficial effects of the utility model are, native system uses compressed air for instrument tank to utilize the instrument compression sky of main factory of existing power plant
The gas that gas allowance storage temperature is high and dry, is transported to the fluidized plate of limestone powder bin, prevents the bonding of agstone.Going out
The bypass duct of a fluidized wind electric heater the most in parallel in feed channel, fluidized wind electric heater is only used as stand-by equipment under normal circumstances,
Only just open to when cannot meet use condition when the gas temperature in tank is low, but this situation seldom occurs.Use fluidized wind
During electric heater, close the electrodynamic valve on outlet pipe, introduce gas into the bypass duct at fluidized wind electric heater place, pass through
The heat effect of this fluidized wind electric heater so that gas temperature raises, and meets use condition, prevents because of gas original temperature not
The situation that limestone powder bin that is sufficient and that cause bonds occurs.Native system simplifies prior art processes, simple in construction, reduces station service
Consumption and maintenance workload, it also avoid the fluidized air blower noise of the prior art impact on periphery, it is achieved carrying of total system
Matter potentiation, especially uses native system, owing to using compressed air for instrument, does not haves as prior art in southern high-humidity area
Middle electric heater fault and the situation that causes agstone to bond.
