Abstract
Calcine flue gas environmental protection processing device comprises reduction reactor, heat exchanger, cryrogenic ware, water spraying tank and adsorption tanks, reduction reactor with forge the burning furnace exhanst gas outlet and link to each other, the tube side import of heat exchanger with forge the export of burning furnace bottom and link to each other, reduction reactor's gas outlet passes through the cryrogenic ware and links to each other with water spraying tank, the liquid outlet of cryrogenic ware bottom links to each other with the shell side import of heat exchanger, water spraying tank's gas outlet links to each other with adsorption tanks. The utility model discloses the heat of burning furnace production is forged in the utilization, through nitrogen oxide in the reduction reactor formula flue gas and ammonia pyroreaction, converts nitrogen oxide into environmental protection gaseous nitrogen gas and emptys, has guaranteed to calcine the flue gas denitration environmental protection and has handled, has reasonable in design, moves advantage stable and safe economy.
Description
Technical field
This utility model is related to calcine fume environment protection processing technology field and in particular to a kind of calcining fume environment protection processes dress
Put.
Background technology
Increasingly severe with national requirements for environmental protection, the emission request also more and more higher to nitrogen oxides, domestic calcining dress
The denitration putting such as charcoal element production flue gas is brought into schedule, contains a large amount of NOx, the water of nitrogen oxides and in the air in calcining flue gas
In conjunction with eventually changing into nitric acid and nitrate, nitric acid is one of origin cause of formation of acid rain；It is with other pollutant under certain condition
Photochemical pollution can be produced.Acid rain harm is many, including to health, ecosystem and Architectural Equipment all
Have direct and potentially hazardous.Acid rain can make children immune function decline, and chronic pharyngitiss, Bronchial Asthma rate increase, with
When can make old man's eye, respiratory tract prevalence increase.Acid rain also can make the crops significantly underproduction, and particularly Semen Tritici aestivi, in acid rain
Under the influence of, can the underproduction 13% to 34%.Semen sojae atricolor, vegetable are also easily endangered by acid rain, lead to protein content and yield to decline.
Acid rain endangers also larger to forest and other plant, often makes forest and other plant leaf is withered and yellow, pest and disease damage increases, ultimately cause
Large Scale Death, how to process calcining flue gas becomes urgent problem in industry.
Utility model content
This utility model is directed to the problem that existing calcining flue gas contains nitrogen oxides, there is provided at a kind of calcining fume environment protection
Reason device.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of calcining environmental protection fume processing device, by reduction reactor, heat exchanger, chiller, Water spray tank and adsorption tanks
Composition, reduction reactor is connected with calcining furnace exhanst gas outlet, and the tube side import of heat exchanger is connected with calcining furnace outlet at bottom, reduction
The gas outlet of reactor is connected with Water spray tank by chiller, and the liquid outlet of chiller bottom is entered with the shell side of heat exchanger
Mouth is connected, and the gas outlet of Water spray tank is connected with adsorption tanks.
Operation principle of the present utility model is that fresh liquefied ammonia passes through the high-temperature calcination in the shell side and tube side enter heat exchanger
Thing heat exchange is gasified, and ammonia is entered and reacted generation N in reduction reactor with NOx2And water, NH3Reduction NOx dominant response be：
4NH3+4NO+O2→ 4N2+6H2O
The admixture of gas of reduction reactor is introduced into the water coolant in chiller produce excess of ammonia gas and reaction
Change, the liquefied ammonia of generation enters back in the shell side of heat exchanger, the gas of chiller is entered Water spray tank and by Water spray, gas entered
Row washing, the gas after washing purifies through the physical absorption of adsorption tanks, is finally vented.
This utility model utilizes the heat that calcining furnace produces, by the nitrogen oxides in reduction reactor formula flue gas and ammonia
Pyroreaction, nitrogen oxides is converted to the emptying of environmental protection gas nitrogen it is ensured that calcining denitrating flue gas environmental protection treatment, has design
The advantage of rationally, stable and safety economy.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is the structural representation of this utility model device.
In figure 1 calcining furnace, 2 reduction reactors, 3 heat exchangers, 4 chillers, 5 Water spray tanks, 6 adsorption tanks.
Specific embodiment
As illustrated, a kind of calcining environmental protection fume processing device, by reduction reactor 2, heat exchanger 3, chiller 4, water spray
Drench tank 5 and adsorption tanks 6 to form, reduction reactor 2 is connected with calcining furnace 1 exhanst gas outlet, the tube side import of heat exchanger 3 and calcining furnace
1 outlet at bottom is connected, and the gas outlet of reduction reactor 2 is connected with Water spray tank 5 by chiller 4, the liquid of chiller 4 bottom
Body outlet is connected with the shell side import of heat exchanger 3, and the gas outlet of Water spray tank 5 is connected with adsorption tanks 6.
Operation principle of the present utility model is that fresh liquefied ammonia passes through the high-temperature calcination in the shell side and tube side enter heat exchanger
Thing heat exchange is gasified, and ammonia is entered and reacted generation N in reduction reactor with NOx2And water, NH3Reduction NOx dominant response be：
4NH3+4NO+O2→ 4N2+6H2O
The admixture of gas of reduction reactor is introduced into the water coolant in chiller produce excess of ammonia gas and reaction
Change, the liquefied ammonia of generation enters back in the shell side of heat exchanger, the gas of chiller is entered Water spray tank and by Water spray, gas entered
Row washing, the gas after washing purifies through the physical absorption of adsorption tanks, is finally vented.
