Description
Technical field
The present invention is a kind of industrial smoke processing unit, especially a kind of nitrogen oxides that can be eliminated in industrial smoke,
The noxious materials such as mercury can effectively cut down the industry smoke comprehensive processing unit of a large amount of white cigarettes produced in flue gas emission again.
Background technology
At present, desulfurizing tower is only generally separately provided in industrial smoke processing, except sulfur dioxide removal effect is more satisfactory
Outside, the pollutants such as nitrogen oxides, mercury cannot be removed effectively.In order to improve the removal effect of nitrogen oxides and other Toxics,
Also have at present and ozone is added in inlet air stack, but due to the limitation of flue diameter, air velocity is high, and ozone is mixed with flue gas
Close uneven, reaction is incomplete, it is impossible to reaches preferable denitration effect.In addition, the flue-gas temperature handled by desulfurizing tower, that is, wet
Saturation dew-point temperature is low, causes smoke stack emission to produce the phenomenon of a large amount of white cigarettes, therefore occur setting heating unit on chimney
To eliminate the method that chimney emits big white cigarette.But this method needs to consume the substantial amounts of energy, and newly-increased energy consumption is corresponding
Again will increase environmental contaminants.Therefore, the noxious materials such as a kind of nitrogen oxides that can be eliminated in industrial smoke, mercury are designed again
The industry smoke comprehensive processing unit of a large amount of white cigarettes produced in flue gas emission can effectively be cut down, be the skill for needing to solve at present
Art problem.
The content of the invention
The technical problems to be solved by the invention, which are to provide a kind of nitrogen oxides that can be eliminated in industrial smoke, mercury etc., to be had
Noxious material can effectively cut down the industry smoke comprehensive processing unit of a large amount of white cigarettes produced in flue gas emission again.
The present invention solve its technical problem technical solution be：
Industry smoke comprehensive processing unit, is made of desulfurizing tower, heat exchanger and circulation condensation device, import and the industry of heat exchanger
The smokejack connection of stove, the outlet of heat exchanger pass through the inlet communication of pipeline I, circulation condensation device and pipeline II and desulfurizing tower,
The outlet of desulfurizing tower is connected by neat stress flue with the neat stress entrance of heat exchanger, and the neat stress outlet of heat exchanger passes through net cigarette
Gas exhaust pass is connected with chimney, have extension section in heat exchanger input end, is equipped with and some is connected with ozone source in extension section
Ozone nozzle and formed ozone injection area, heat exchanger is as smelly in itself for the neat stress of pending industrial smoke and outer row
Oxygen hybrid reaction area and heat-exchange device.Ozone by ozone be blown area enter ozone hybrid reaction area after with industrial smoke
Fully oxidized reaction occurs for associated gas；Industrial smoke enters circulation condensation device after heat exchange, then into desulfurizing tower；Through
The condensed flue-gas temperature of circulation condensation device is greatly lowered, and the generation of vapor is reduced from source；By with ozone reaction
Industrial smoke afterwards carries out denitration reaction after cooling condenses in tower；Neat stress after reaction enters heat by exhaust pass and hands over
Changing device exchanges heating, by neat stress exhaust pass by smoke stack emission to air after heating.
As a preferred embodiment of the present invention, heat exchanger is installed on supporting rack.
As a preferred embodiment of the present invention, the material for making heat exchanger is corrosion resistant material.
Compared with prior art, the present invention due to（1）Ozone injection area and ozone mixed zone are added before desulfurizing tower, is made smelly
Oxygen has the room and time come into full contact with hybrid reaction with industrial smoke, and the reaction was complete, improves denitration efficiency；（2）Add
Former flue-gas temperature is greatly lowered in circulation condensation device, and the generation of vapor is reduced from source；（3）Add heat-exchange device pair
The flue gas heating that wet desulphurization produces, reduces the wet saturation dew point of flue gas, effectively cuts down big white cigarette.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
As shown in the figure, industry smoke comprehensive processing unit, is made of desulfurizing tower II, heat exchanger I and circulation condensation device III,
The import of heat exchanger I is connected with the smokejack 1 of industrial furnace, and the outlet of heat exchanger I passes through pipeline I 6, circulation condensation device III and pipe
The inlet communication in road II 8 and desulfurizing tower II, the outlet of desulfurizing tower II pass through neat stress flue 10 and the neat stress entrance of heat exchanger I
11 connections, the neat stress outlet of heat exchanger I are connected with chimney 12 by neat stress exhaust pass 13, had in heat exchanger I input end
Extension section 3, is equipped with some ozone nozzles connected with ozone source in extension section 3 and forms ozone injection area, to pending
Heat exchanger I is ozone hybrid reaction area and heat-exchange device in itself for industrial smoke and the neat stress of outer row.
Heat exchanger I is installed on supporting rack IV.
The material for making heat exchanger I is corrosion resistant material.
