Abstract
Carbon dioxide recovering device has a gas holder, an air exhauster, a carbon removal tower, a pressure can and a pressure control valve connected in turn on a recovering pipe. The device can recover the carbon dioxide effectively which is released in the gas-making procedure of small nitrogen fertilizer production, make full use of the heat carried by carbon and carbon dioxide, so as to reduce the consumption of coal, and the effect is obvious. The device also can recover the carbon dioxide released in the other places, which optimizes the environment and makes full use of carbon.
Description
Technical field
The utility model relates to a kind of retrieving arrangement, specifically, is to reclaim carbon dioxide plant.
Technical background
In the gas making operation of traditional little nitrogen fertilizer production process, by the CO and the CO of producer gas generator generation
2Be used as blowing air and send into the roasting kiln burning, the heat of generation is admitted to boiler for producing steam.CO after being utilized
2Gas together with its entrained heat by from smoke stack emission.Like this, both waste a large amount of carbon, wasted heat again.This also is a higher important factor of coal consumption in the little nitrogen fertilizer production.
Goal of the invention
The purpose of this utility model is a kind of recovery CO of design
2Device, the CO that is discharged
2Recycle,, reduce the purpose of calorific loss to reach the reduction coal consumption.
Technical scheme
The utility model is to realize purpose of design like this.Discharge outlet at chimney is connected to recovery channel; On recovery channel, be connected to gas holder, vacuum fan, decarbonizing tower, pressure-pot and variable valve successively; The end of recovery channel inserts the producer inlet.
When discharge outlet has CO
2When gas is discharged, directly enter gas holder, start vacuum fan then, containing CO in the gas holder
2Gas suck the decarburization stove, in decarbonizing tower, use propylene carbonate with CO
2Gas adsorption improves CO
2Concentration is removed undesired impurities simultaneously.Allow high concentration CO then
2Gas enters pressure-pot pressurization storage.When needing to use, by variable valve, CO
2Feed producer.At this moment, CO
2In C can fully obtain utilizing CO
2Entrained heat also can utilize.
Description of drawings
Accompanying drawing is a synoptic diagram of the present utility model
Embodiment
Below in conjunction with accompanying drawing one non-limiting examples is illustrated.Present embodiment is to reclaim the CO that the gas making operation is discharged in the little nitrogen fertilizer production process
2Be example.Discharge outlet 4 at chimney 5 takes back receipts pipeline 6; On recovery channel 6, be connected to gas holder 7, vacuum fan 8, decarbonizing tower 9, pressure-pot 10 and variable valve 11 successively; Recovery channel 6 ends link to each other with the inlet 12 of producer 1.
During use, as the CO and the CO of producer 1 generation
2Be admitted to after roasting kiln 2 burning as blowing air, heat is admitted to boiler 3 and produces water vapors.Contain CO after being utilized
2Gas enters gas holder 7 through the discharge outlet 4 of chimney 5 through recovery channel 6, by vacuum fan 8 suction decarbonizing towers 9, in decarbonizing tower 9, uses the propylene carbonate CO absorption again
2Gas improves CO
2Concentration, removal of contamination.The CO that concentration is higher
2Gas is admitted to pressure-pot 10 pressurization storages.When needing, open relief valve 11, CO
2Gas 12 is sent into tower 1 is taken place from entering the mouth.CO like this
2In C and the heat of being with can be utilized once more, can effectively reduce coal consumption.
The utility model technology is reasonable, makes simply, is fit to the transformation to existing little nitrogen fertilizer production line, also can reclaim the CO that discharge in other place
2, can turn waste into wealth.
