Description
Technical field
This utility model relates to a kind of calcium carbonate ammonium hydrogen carbonate combined desulfurization and denitration device.
Background technology
Along with stepping up of environmental consciousness and requirement, most domestic boiler enterprise is the most supporting desulfuring and denitrifying apparatus, as a example by SNCR denitration system, when employing carbamide is denitration medicament, there is reaction efficiency the highest, the problems such as medicament utilization rate is on the low side, and operation cost is bigger.And when to use ammonia or liquefied ammonia be medicament, there is again the problem in terms of the safety to environment and staff, once leakage may jeopardize personal safety, cause major accident.
Utility model content
This utility model is according to above not enough, it is provided that a kind of calcium carbonate ammonium hydrogen carbonate combined desulfurization and denitration device.
The technical solution of the utility model is:
A kind of calcium carbonate ammonium hydrogen carbonate combined desulfurization and denitration device, is characterized in that, including:
Calcium carbonate feeding chamber, in funnel-form, is used for holding calcium carbonate；
The outlet of calcium carbonate valve, import and calcium carbonate feeding chamber；
Ammonium hydrogen carbonate feeding chamber, in funnel-form, is used for holding ammonium hydrogen carbonate；
The outlet of ammonium hydrogen carbonate valve, import and ammonium hydrogen carbonate feeding chamber；
Blender, the outlet of top connection calcium carbonate valve and the outlet of ammonium hydrogen carbonate valve；
Ejector, the outlet of charge door connection blender, air intake vent connection power wind regime；
Coal-burning boiler, its boiler furnace connects with the nozzle of ejector, and nozzle can spray calcium carbonate ammonium hydrogen carbonate mixed powder.
For accurate measurement, also include:
Calcium carbonate flow meter, calcium carbonate flow meter is serially connected between described calcium carbonate valve and described blender
Ammonium hydrogen carbonate effusion meter, ammonium hydrogen carbonate effusion meter is serially connected between described ammonium hydrogen carbonate valve and blender.
As preferably, described blender is electric machine agitator.
As preferably, described ejector is acid and alkali-resistance ejector.
Preferred scheme is, described calcium carbonate valve is metering valve, and described ammonium hydrogen carbonate valve is metering valve.I.e. save calcium carbonate flow meter and ammonium hydrogen carbonate effusion meter.
Effusion meter is concatenated between described blender and described ejector.
This utility model, owing to using ammonium hydrogen carbonate as denitrfying agent, substitutes original conventional carbamide, does not the most use catalyst, have the effect of higher denitration effect, and reaction temperature window is wider.There is again the prominent safety being similar to carbamide simultaneously.
Owing to using ammonium hydrogen carbonate as denitrfying agent, it can be presented in solid.Temperature needed for being decomposed into ammonia is the most relatively low, therefore can send into the positions such as boiler furnace in the way of using powder body direct-injection, directly reacts with NOX, is translated into N2.Thus make to reduce the complexity aspect of whole system, become a reality.Can use and be similar to the hardware device that furnace sorbent injection desulfurization system is similar, reach required denitration effect.Save equipment investment, reduce operation maintenance cost
Use ammonium hydrogen carbonate and calcium carbonate associated form denitration, desulfurization, the then engineering design that can reduce whole atmospheric purification system, the cost making, installing, save the space shared by facility, and shorten the construction period of engineering.
Ammonium hydrogen carbonate is safety and clean chemical substance, and the catabolite of itself is NH3, H2O and CO2, is again solid-state simultaneously.Environment will not be had adverse effect on.It is rela-tively easy to manage and stores.Without the storage management system configuring complexity as liquefied ammonia/ammonia.
This utility model has simple in construction, installs that maintenance cost is low, the beneficial effect of Environmental Safety.
