Description
Technical field
The invention belongs to eliminate the device and removing method technical field of the hangover of fuel boiler flue gas, more particularly to one kind disappears
The device and removing method trailed except fuel boiler flue gas.
Background technology
In the non-fire coal such as coal-fired thermal power plant, the coal-burning boiler of coke-oven plant and garbage burning factory, steel-making enterprise machine glass factory
Burning boiler, including semi-coke boiler, natural gas boiler, biomass boiler etc..The flue gas that original boiler combustion is produced directly is arranged
It is put into air, because, containing harmful substances such as dust and sulfur dioxide, directly discharge can cause certain dirt to air in flue gas
Dye.Inner wall of stack is needed with corrosion proof function, and chimney cost is higher, and chimney service life is short.In order to reduce smoke pollution,
Desulfuration absorbing tower will increased between chimney and boiler, to absorb the dust in flue gas, sulfur dioxide etc..But after desulfurization and dedusting
Flue gas in carry dusts, massless micronic dust containing a large amount of（Such as PM10, PM2.5）Arranged with the vapor of aerosol by chimney
It is put into air, following harm can be produced：Although first, having in the flue gas of discharge without big dust particle and sulfur dioxide etc.
Evil material, but carry dust, massless micronic dust containing a large amount of（Such as PM10, PM2.5）Pass through chimney with the vapor of aerosol
It is discharged into air, the formation of haze is added to a certain extent, a certain degree of pollution is caused to air；Second, flue gas
In contain a large amount of vapor, cause current to lose serious, the water that one 10 tons of coal-burning boiler is lost by desulfurizer is per hour
More than 9 tons, the water of the desulfurizer loss of 30MW medium-sized Thermal generation unit reaches more than 110 tons, and water resources consumption is big, into
This increase；Third, flue-gas temperature is high, the heat energy in flue gas is wasted；Fourth, needing to set clean flue gas cigarette after desulfurization
Road, the big system of the desulphurization system pressure loss increase of power consumption loss per hour 100kWh；Fifth, contain a large amount of vapor in flue gas,
" white cigarette " is formed above chimney, it is panic that city dweller produces psychology.
The content of the invention
The invention solves the problems that first technical problem be just to provide dust in a kind of reduction flue gas discharge into air, time

Stop flue dust；
3rd step, condensation is reclaimed
Flue gas after filtering is passed through in condensation chamber, is condensed and reclaimed by condenser, the Water vapor condensation in flue gas is turned into liquid
Drip and pool water and flow out recovery from condensate liquid recovery port, while the liquid in condenser pipe is heated；
4th step, demisting is reclaimed
Condensed flue gas is passed through in demisting room, is condensed to remove the fine droplet in flue gas by demister and is reclaimed；
5th step, in heating heating indoor
By the flue gas after demisting in heating heating indoor, the temperature of flue gas at heating chamber outlet is set to reach 80 DEG C -115 DEG C；
6th step, discharges flue gas
Flue gas after heating is discharged from exhanst gas outlet.
The device and removing method provided by the present invention for eliminating the hangover of fuel boiler flue gas compared with prior art, has
Advantages below：First, due to including positioned at the desulfuration absorbing tower of lower end and the chimney above the desulfuration absorbing tower, in institute
State and be provided with gas approach below desulfuration absorbing tower, the chimney is successively from bottom to up：Mechanical water filter chamber, condensation chamber, remove
Fog chamber, heating chamber and exhanst gas outlet, are provided with mechanical water filter in the mechanical water filter chamber, are set in the condensation chamber
Condenser is equipped with, condensate liquid recovery port is provided with below the condensation chamber, demister is provided with the demisting room, in institute
State and having heaters is set in heating chamber, first filtered out the mechanical water in flue gas by mechanical water filter, in filter process
In, the filtrating smoke dust part in flue gas can also further be purified flue gas, flue gas is reached after condenser, in flue gas
Vapor, which runs into, condenses into water droplet after condenser, one 10 tons of coal-burning boiler can from flue gas water lift per hour more than 8 tons,
30MW medium-sized Thermal generation unit can reach more than 100 tons by water lift from flue gas, and Water Sproading rate is up to more than 90%, condensation
Water afterwards flows out from the condensate liquid recovery port below condensation chamber to be recycled, and is reduced water consume, has been saved liquid in cost, condenser
Temperature can be increased to 40 DEG C -45 DEG C, the elevated condensed fluid of temperature is also used as the thermals source such as central heating, further section
The about energy；By containing fine droplet in the flue gas of condensation, after demister demisting, the moisture in flue gas is less, then passes through
, it is necessary to heat is few when crossing heater heating, energy consumption during heating is greatly reduced, it is not necessary to reset clean flue gas passage,
The desulphurization system pressure loss can effectively reduce by 500-700Pa, and system saves power consumption more than 100kWh per hour, due in flue gas
Water vapour content is low, therefore the dust quantity that the heated flue gas being discharged into air is carried is low, and the cigarette above chimney
Gas exit portion will not form flue gas hangover, and the psychology for eliminating city dweller is panic；Second, due to the section of the heating chamber
For rhombus, the heater is heat-exchange tube, and the section of the condensation chamber is rhombus, and the condenser is condenser pipe；The heat
It is 2-50 degree to exchange the angle of inclination of pipe, and the angle of inclination of the condenser pipe is 2-50 degree, increases flue gas and heat-exchange tube
And the contact area of condenser pipe, equipment volume is reduced, while the flow direction of condensed water is controlled, returning for condensed water is facilitated
Receive, heating chamber volume reduces, it is therefore prevented that equipment is top-heavy, increase the stability of equipment；Third, because the demister is room
Ridge formula demister, the fine droplet in demisting room can be removed into very well, flue gas reclaimed water in heating chamber is further lowered into
The content of steam.
