Description
[technical field]
The present invention relates to the technical field of wet flue gas " taking off white ", especially a kind of flue gas takes off white device.
[background technique]
The desulfurization of most domestic at present all uses wet desulphurization, and wet desulphurization is absorbed in flue gas by a large amount of slurries
Acidic materials, to achieve the purpose that remove pollutant, flue gas is excluded in the form of being saturated wet flue gas from chimney after washing,
Wet desulphurization exit gas temperature is general between 50 DEG C -60 DEG C, after the saturation wet flue gas of heat touches surrounding air, flue gas quilt
Cooling, the water vapour in flue gas is precipitated by way of droplet, forms a large amount of white plume.In order to eliminate white plume
Visual pollution, further in-depth removing pollutant, national and local governments have put into effect flue gas in succession and have taken off white policy document, it is desirable that
Eliminate the visual pollution of white plume, the call of various regions enterprise also active response country and government strives and does " smokeless factory "
The one or several kinds of forms combined for taking off white technology at present mainly and having condensation, cool and heat, northern area one
As use condensation technology, southern area generally uses MGGH technology or MGGH+ condensation technology, wherein to be divided into flue gas again cold for condensation
The condensation of solidifying and slurries cools and heats the general form heated using MGGH or heat source, however the prior art is lacked there are following
Point:
Slurries condensation is the slurry temperature by reducing absorption tower spray, to achieve the purpose that cooled flue gas, slurries are cold
Although solidifying system is simple, one-time investment is low, there are problems that slurry heat exchanger abrasion and leakage, influences the stabilization of system
Property, while the water of the condensation in flue gas is directly entered slurries, can not be recycled.
Flue gas condensing can be condensed and be sprayed two kinds of forms of condensation using heat exchanger, mostly used the form of heat exchanger greatly, adopted
With fluoroplastics or Steel Pipe Heat Exchanger, teflon heat exchanger one-time investment is big, and arrangement form is single, and Steel Pipe Heat Exchanger uses the longevity
Order short, the phenomenon that being easy to appear corrosion.
Flue gas mostly uses greatly MGGH, and heat medium water is used to form enclosed as medium, gas cooler and flue gas heater
Circulation, but in some special cases or it is other do not have using MGGH in the case where, it is necessary to using other heat source come add
Hot fume makes its satisfaction take off white requirement.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, proposes that a kind of flue gas takes off white device, cigarette can be reached
The white environmental requirement of qi exhaustion.
To achieve the above object, the invention proposes a kind of flue gases to take off white device, including successively according to flow of flue gas direction
The absorption tower of setting, condenser, demister, hot wind turbulator, chimney further include the hot-blast stove that is connected with hot wind turbulator, described
The exhaust pass on absorption tower is connected with condenser, and the condenser passes through demister and the hot wind turbulator for heating flue gas
It is connected, the hot-blast stove is burnt by chemical fuel provides heat source for hot wind turbulator, and the hot wind turbulator produces hot-blast stove
The saturation wet flue gas direct contact heat transfer of raw high temperature and condensator outlet makes its overheat, the chimney for will cross hot fume into
Row discharge.
Preferably, the condenser uses fluorine plastic-steel condenser.
Preferably, the saturation wet flue gas of the hot wind turbulator and condensator outlet uses direct contact heat transfer.
Preferably, the hot-blast stove generates high-temperature flue gas using chemical fuel burning, the chemical fuel includes solid
Fuel, liquid fuel and gaseous fuel.
Preferably, the upper end of the condenser is equipped with the cooling water inlet that communicates with condensation pipe, lower end be equipped with it is cold
The cooling water outlet that solidifying pipeline communicates.
Beneficial effects of the present invention: the present invention passes through absorption tower, condenser, demister, hot wind turbulator, chimney, hot wind
The cooperation of furnace etc., condenser are arranged in desulfurizing tower outlet, and condenser uses fluorine plastic-steel condenser, and condensed flue gas is added again
Heat carries out direct contact heat transfer to flue gas in such a way that chemical fuel burns and generates heat, increases flue-gas temperature, reach
Take off white environmental requirement.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram that a kind of flue gas of the present invention takes off white device.
[specific embodiment]
A kind of flue gas of the invention takes off white device refering to fig. 1, including set gradually according to flow of flue gas direction absorption tower 1,
Condenser 2, demister 3, hot wind turbulator 4, chimney 6 further include the hot-blast stove 5 that is connected with hot wind turbulator 4, the absorption tower 1
Exhaust pass be connected with condenser 2, the condenser 2 by demister 3 be used to heat 4 phase of hot wind turbulator of flue gas
Even, the hot-blast stove 5 is burnt by chemical fuel provides heat source for hot wind turbulator 4, and the hot wind turbulator 4 is by hot-blast stove 5
The saturation wet flue gas contact heat-exchanging that the high temperature and condenser 2 of generation export makes its overheat, and the chimney 6 is used for hot wind turbulator
The flue gas of 4 overheats generated is discharged.The condenser 2 uses fluorine plastic-steel condenser, both has the advantages of Steel Pipe Heat Exchanger,
But also with very strong corrosion resistance.The hot wind turbulator 4 uses direct contact heat transfer with the wet flue gas that condenser 2 exports,
Heat exchange efficiency is high, and heat loss is small, and equipment is also relatively easy.The hot-blast stove 5 generates high-temperature flue gas, institute using chemical fuel burning
Stating chemical fuel includes solid fuel, liquid fuel and gaseous fuel.The upper end of the condenser 2 is equipped with and communicates with condensation pipe
Cooling water inlet, lower end is equipped with the cooling water outlet that communicates with condensation pipe.
The course of work of the present invention:
A kind of flue gas of the present invention takes off white device, and former flue gas is emitted into condenser 2 from exhaust pass by absorption tower 1, after condensation
Flue gas heated again, hot-blast stove 5 is burnt by chemical fuel, and to generate high-temperature flue gas be 4 heat supply of hot wind turbulator, and high temperature is straight
Connect with condenser 2 export saturation wet flue gas direct contact heat transfer, make its overheat, thus achieve the purpose that take off it is white, overheat
Flue gas is discharged eventually by chimney 6, is reached and is taken off white environmental requirement, and wherein condenser 2 uses fluorine plastic-steel condenser, both has steel
The advantages of heat exchange of heat pipe, but also with very strong corrosion resistance, flue gas uses hot wind direct contact heat transfer, heat exchange efficiency
Height, heat loss is small, and equipment is also relatively easy.
Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention
Scheme all belong to the scope of protection of the present invention.
