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 water saving fixtures.
[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.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, propose that a kind of flue gas takes off white water saving fixtures, Neng Gouda
White environmental requirement is taken off to flue gas, while eliminating multicomponent pollutant, moreover it is possible to which the moisture in high-quality collection wet flue gas carries out again
Secondary utilization, to achieve the purpose that water-saving.
To achieve the above object, take off white water saving fixtures the invention proposes a kind of flue gas, including by flow of flue gas direction according to
The deduster of secondary setting, air-introduced machine, absorption tower, are connected with air-introduced machine between the deduster, absorption tower, the air-introduced machine is used for
Flue gas in deduster from boiler is introduced into absorption tower, is successively arranged from bottom to top along flow of flue gas direction in the absorption tower
Spraying layer, level-one demister, water collector, second level demister, the water collector include water collection device, condenser, the receipts water
Device is set to the lower section of condenser for collecting condensate liquid, and the water collection device is connected by overflow pipe with baffle-box, the receipts
The condensate liquid that hydrophone is collected enters baffle-box by overflow pipe gravity flow and is recycled, and the spraying layer passes through slurries pipeline
Being connected with absorb the bottom of the tower stock tank, is equipped on the slurries pipeline for sending absorb the bottom of the tower slurries to the slurries of spraying layer
Circulating pump.
Preferably, being evenly equipped with several slurry nozzles being connected with slurries pipeline on the spraying layer.
Preferably, the condenser uses fluorine plastic-steel condenser.
Preferably, one end of the condenser is equipped with the cooling water inlet that communicates with condensation pipe, the other end be equipped with
The cooling water outlet that condensation pipe communicates.
Beneficial effects of the present invention: the present invention passes through the cooperation on deduster, air-introduced machine, absorption tower etc., and in absorption tower
Spraying layer, level-one demister, water collector, second level demister are set, flue-gas temperature can be effectively reduced, it is de- that flue gas can be reached
White purpose, while multicomponent pollutant is eliminated, wherein water collector is directly arranged at the knot on absorption tower top using condenser
Structure, can moisture in high-quality collection wet flue gas, utilized again, to achieve the purpose that water-saving.It is changed using fluorine plastic-steel
Hot device, both with the characteristic of Steel Pipe Heat Exchanger, but also with very strong Corrosion Protection.
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 water saving fixtures.
[specific embodiment]
A kind of flue gas of the invention takes off white water saving fixtures refering to fig. 1, including the deduster set gradually by flow of flue gas direction
