Description
Technical field
Field of Environment Protection is the utility model is related to, more particularly to a kind of boiler waste gas treating device.
Background technology
Boiler is the capital equipment of northern area heating, and the boiler of some areas still does fuel using coal.After coal combustion
Produce substantial amounts of CO2, a small amount of CO, NO, NO2、SO2And dust etc., it is one of main source of atmosphere pollution.CO2It is to cause
The arch-criminal of greenhouse effects, CO are toxic gases, and NO is easily oxidized into NO2, NO2And SO2It is the composition to form acid rain
One of.These gases seriously pollute environment and influence health, and coal fired boiler needs to be handled before waste gas is discharged.Mesh
Before, the boiler waste gas of part Thermal Corp is unprocessed to be directly discharged into air.
The content of the invention
The shortcomings that in order to overcome above-mentioned prior art, the purpose of this utility model are to provide a kind of boiler waste gas processing dress
Put, it is simple and practical, securely and reliably.
In order to achieve the above object, the technical scheme that the utility model is taken is：
A kind of boiler waste gas treating device, including including boiler smoke air inlet 3, include the top of boiler smoke air inlet 3
Electrostatic precipitation module 4 is provided with, the gas outlet of the electrostatic precipitation module 4 connection air inlet of oxidation module 5, the gas outlet of oxidation module 5 connects
The air inlet of caustic soda circulation fluid module 6 first is connect, caustic soda circulation fluid module 6 is provided with gas sensor module 7, caustic soda at gas outlet
The gas outlet of circulation fluid module 6 connects the air inlet of solenoid valve module 8, the air inlet of the first gas outlet connection chimney 9 of solenoid valve module 8
Mouthful, the second air inlet of the second gas outlet connection caustic soda circulation fluid module 6 of solenoid valve module 8.
First signal output part of the signal input part connection controller 2 of described electrostatic precipitation module 4, oxidation module 5
Signal input part connects the secondary signal output end of controller 2, the signal input part of caustic soda circulation fluid module 6 connection controller 2
3rd signal output part, the signal input part of the signal output part connection controller 2 of gas sensor module 7, solenoid valve module 8
Signal input part connection controller 2 the 4th signal output part；The electricity of the power input end connection power module 1 of controller 2
Power output end.
The beneficial effects of the utility model are：
The adsorption of dust particle of electrostatic precipitation module 4；O in the air inlet of oxidation module 52CO, NO are oxidized to CO2、NO2
Meanwhile part SO2It is oxidized to SO3, the reaction is reversible reaction；When waste gas passes through caustic soda circulation fluid module 6, soda bath
(NaOH solution) respectively with the CO in waste gas2、NO2、SO2And SO3Generation chemical reaction generation NaCO3、NaNO3、Na2SO3With
Na2SO4；Worked well with energy-conserving and environment-protective, safe and reliable, exhaust-gas treatment, there is higher practicality.
Brief description of the drawings
Accompanying drawing 1 is block diagram of the present utility model.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
Reference picture 1, a kind of boiler waste gas treating device, including including boiler smoke air inlet 3, include boiler smoke air inlet
3 top is provided with the electrostatic precipitation module 4 for removing the dust in waste gas, the connection oxidation of the gas outlet of electrostatic precipitation module 4
The air inlet of module 5, for CO, NO a small amount of in waste gas are oxidized into CO2、NO2, the gas outlet of oxidation module 5 connection caustic soda circulation fluid
The air inlet of module 6 first, for absorbing the CO in waste gas2、NO2And SO2(a small amount of SO3), at the gas outlet of caustic soda circulation fluid module 6
Gas sensor module 7 is provided with, for detecting the CO in waste gas2、NO2、SO2、SO3Whether absorbed by soda bath and reach row
Put index；The gas outlet of caustic soda circulation fluid module 6 connects the air inlet of solenoid valve module 8, the first gas outlet connection of solenoid valve module 8
The air inlet of chimney 9, the second air inlet of the second gas outlet connection caustic soda circulation fluid module 6 of solenoid valve module 8.
First signal output part of the signal input part connection controller 2 of described electrostatic precipitation module 4, oxidation module 5
Signal input part connects the secondary signal output end of controller 2, the signal input part of caustic soda circulation fluid module 6 connection controller 2
3rd signal output part, the signal input part of the signal output part connection controller 2 of gas sensor module 7, solenoid valve module 8
Signal input part connection controller 2 the 4th signal output part；The electricity of the power input end connection power module 1 of controller 2
Power output end.
This uses new operation principle：
In use, controller 2 controls electrostatic precipitation module 4 to be used for removing the dust in waste gas, change module 5 and be used for waste gas
In a small amount of CO, NO be oxidized to CO2、NO2, caustic soda circulation fluid module 6 is used for absorbing CO in waste gas2、NO2And SO2It is (a small amount of
SO3), gas sensor module 7 is used for detecting the CO in waste gas2、NO2、SO2、SO3Whether reach discharge by soda bath absorption to refer to
Mark, when the gas seted off reaches standard, controller 2 controls solenoid valve module 8 to be up to the gas of index and arranged to chimney 9, works as combustion
The gas put is not up to standard, and controller 2 controls solenoid valve module 8 to send the waste gas to fall short of the target feedback to caustic soda circulation
Liquid module 6.
