Description
Technical field
The present invention relates to field of environment protection, and in particular to a kind of flue gas recirculation processing system.
Background technology
In power plant and waste treatment plant, solid fuel can produce air pollutants, such as titanium dioxide in combustion
The pernicious gases such as sulphur, hydrogen chloride, mercury.During typical fume treatment, a suction is often set in the downstream of combustion process
The reagents such as closed cans, gas combustion product and calcium hydroxide are contacted or mixed in the tourie, and pernicious gas is carried out with the reagent
Reaction, produces the solid particle being suspended in flue gas stream.The removal that these solid particles are subsequently disposed in tourie downstream is set
It is standby, such as fabric filter or electrostatic precipitator removing, achieve the purpose that to reduce pollution.In some smoke processing systems, also exist
Water is added in flue gas, for improving reaction speed.
During traditional fume treatment, the solid particulate matter to suspend in flue gas is since gravity can be deposited on tourie
Bottom, influences the reaction of pernicious gas and reagent, causes pernicious gas removal in flue gas to be not thorough.
The content of the invention
In conclusion being overcome the deficiencies in the prior art, the technical problems to be solved by the invention are to provide a kind of flue gas
Recycling processing system.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of flue gas recirculation processing system, including absorb
Tank, particle eliminating equipment and filter；The examination being internally provided with pernicious gas reaction generation particle in flue gas of the tourie
Agent, its entrance input combustion product gases, it is exported first is connected after the particle eliminating equipment of the particle removal of generation by defeated smoke pipe
Reconnect filter；The filter band is useful for wind of the guiding flue gas from the tourie along defeated smoke pipe toward filter flow
Fan；The relatively described filter of defeated smoke pipe position punishment in downstream on flow of flue gas direction is two branches, wherein
Part of smoke is back in the tourie by circulation pipe and makes to be formed in tourie by one branch with certain speed to be subtracted
The aerodynamic turbulence of slow particulate matter precipitation, another branch continue conveying flue gas and move ahead.
The beneficial effects of the invention are as follows：The solid particulate matter for preventing from suspending in flue gas is deposited on absorption pot bottom, ensures have
Evil gas and reagent effecting reaction, thoroughly remove the pernicious gas in flue gas.
Based on the above technical solutions, the present invention can also be improved as follows：
Further, the holder for absorbing the particulate matter that pot bottom is equipped with for settlement on storage, the holder are upper
Small conulite under big.
Further, described circulation pipe one end connects the defeated smoke pipe, its other end connects the bottom of the holder.
It is using the above-mentioned further beneficial effect of scheme：Strengthen the effect of the aerodynamic turbulence produced in tourie.
Further, the circulation pipe is equipped with the fluid control for being used for adjusting its inside smoke flow velocity.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In attached drawing, parts list represented by the reference numerals is as follows：
1st, tourie, 2, particle eliminating equipment, 3, filter, 4, defeated smoke pipe, 5, circulation pipe, 6, holder, 7, fluid control
Device processed.
Embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in Figure 1, a kind of flue gas recirculation processing system, including tourie 1, particle eliminating equipment 2 and filter 3；
The reagent being internally provided with pernicious gas reaction generation particle in flue gas of the tourie 1, its entrance input combustion product gases, its
Outlet reconnects filter 3 after first connecting the particle eliminating equipment 2 for removing the particle of generation by defeated smoke pipe 4；The filtering
3 band of device is useful for the fan that guiding flue gas is flowed from the tourie 1 along defeated smoke pipe 4 toward filter 3；4 phase of defeated smoke pipe
To the filter 3, the position punishment in downstream is two branches on flow of flue gas direction, wherein a branch is by following
Part of smoke is back in the tourie 1 and makes to be formed in tourie 1 by endless tube 5 with certain speed slows down particulate matter precipitation
Aerodynamic turbulence, another branch continue convey flue gas move ahead.1 bottom of tourie is equipped with the particulate matter for settlement on storage
Holder 6, the holder 6 is up big and down small conulite.Described 5 one end of circulation pipe connects the defeated smoke pipe 4, its is another
End connects the bottom of the holder 6, and the fluid control for being used for adjusting its inside smoke flow velocity is equipped with the circulation pipe 5
7。
Combustion product gases are introduced into tourie 1, its pernicious gas carried suspends in tourie 1 with reagent reacting generation
Solid particulate matter, the solid particulate matter of generation along defeated smoke pipe 4 enters in particle eliminating equipment 2 and removes with flue gas
Fall.Flue gas reaches filter 3 and carries out filtration treatment after particle eliminating equipment 2, and the part in flue gas after filtering is along following
Endless tube 5, which enters, forms aerodynamic turbulence in holder 6, aerodynamic turbulence can slow down suspended solid in the flue gas in holder 6
The settling velocity of grain thing, makes suspended solid particles thing down downstream and carry out corresponding filtration treatment with flue gas.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention.
