Inside carries out desulphurization denitration process, and the flue gas generated in the whole process enters steel flue gas duct main body 3 by sulfuric acid tower main body 1
Interior, at this moment, the smoke moisture come out by sulfuric acid tower main body 1 is big, and temperature is about at 55 DEG C or so, and then flue gas passes through one section of removing
The steel flue gas duct main body 3 of steel flue gas duct insulating layer 4 carries out natural cooling, while the length of steel flue gas duct main body 3 increases, and makes flue-gas temperature base
Originally it is reduced to natural temperature, so that the moisture in flue gas be precipitated, the absolute content of " white cigarette " in flue gas is reduced, then, in flue gas
The cooling condensed water being precipitated is discharged by condensation-water drain 5；
Then, the flue gas after dehumidifying goes successively to 3 concatenated heaters 6 and is internally heated work, at this moment, will
The saturated vapor that extraneous waste-heat recoverer generates is entered in heater 6 by steam inlet 7, and then is mentioned well for heating flue gas
Supplying heat source, flue gas flow into heater 6 in the horizontal direction, then, are transported to chimney 9 by heater 6 and are discharged, and then pass through heating
Device 6 improves the temperature of flue gas, flue-gas temperature is heated to 85 DEG C or so, to reduce in flue gas the relative amount of " white cigarette ", together
When during heating as shown in Fig. 4, compressed air is input to by extraneous compressor and is blowed and sprayed in branch pipe 12, together
When, it is controlled by solenoid valve 11, is constantly blown into heater 6 so that blowing and spraying branch pipe 12, so that compression
The dust accumulation in heater 6 is purged to air periodic, and then the dust in flue gas is prevented to be attached on the tubulation of heater 6, is connect
, the condensate return that steam (vapor) outlet 8 comes out is entered in the softening water tank of waste-heat recoverer and is collected, is recycled for waste heat
The moisturizing of device, flue gas condensing reheat technical treatment after the flue gas of desulphurization denitration dedusting, and " Bai Yu " phenomenon of discharged gas fume is big
To improve, and the steam cooling water recycled is fully used, and water-saving also 48 tons or so daily, has good social benefit
