Liquid-absorbant relatively more commonly used at present has monoethanolamine etc., and kind of refrigeration cycle working medium commonly used is to having ammonia-aqueous solution (ammonia is cold-producing medium, and water is absorbent), water-lithium bromide solution (water is cold-producing medium, and lithium bromide is an absorbent) etc.Wherein adopt ammonia-aqueous solution workmanship confrontation can produce the low temperature below 0 ℃; Because the cold-producing medium of lithium-bromide absorption-type refrigerating machine is a water, cryogenic temperature can only generally be not less than 5 ℃ more than 0 ℃.Be that example illustrates the workflow of this system with monoethanolamine (MEA) and ammonia-aqueous solution below.
In flow process shown in Figure 2, power-plant flue gas is admitted to absorption tower 2, and in absorption tower 2, the carbon dioxide in the flue gas is absorbed by MEA solution, contains the CO that does not catch on a small quantity after the purification
2Flue gas send into chimney from cat head and discharge.Absorbed CO
2The MEA rich solution flow into poor rich liquid heat exchangers 6 through rich solution pump 5, in poor rich liquid heat exchanger 6, utilize the waste heat of the absorbent solution (lean solution) after the regeneration that rich solution is heated, also reach the effect of cooling actified solution simultaneously.The MEA rich solution enters in the regenerator 3 through the top of choke valve 7 by regenerator 3, provides the energy heating to make absorbent MEA regeneration by solar facilities 1 auxiliary bleeding.Then lean solution is sent into reboiler 10, utilized auxiliary the bleeding of solar energy to heat the further desorb of carbon dioxide that makes wherein.Lean solution behind the desorb carbon dioxide flows out from regenerator 3 bottoms, by lean pump 8 pressurizations, enters absorption tower 2 again after delivering to 4 coolings of lean solution cooler after poor rich liquid heat exchanger 6 heat exchange.Circulation constitutes the flow process of continuous absorption and desorption carbon dioxide thus.
The pure CO that comes out from regenerator 3
2Enter separator 10 behind the concentrated ammonia liquor heat-shift in stream and the generator 13 and carry out carbonated drink and separate, condensed water returns regenerator by solution pump 9, and isolated carbon dioxide enters dehydrator 11 and removes moisture, enters CO2 storage container 12 then.Concentrated ammonia solution is heated in generator 13, and saturated ammonia is separated from solution and entered condenser 14, is saturated liquid ammonia through water quench in condenser.Liquid ammonia becomes the very little wet saturated ammonia steam of mass dryness fraction through choke valve step-down, cooling, entering that heat absorption becomes dried saturated ammonia steam in the evaporimeter 15, enters absorber 17 then and is dissolved by dilute ammonia solution, and the liberated heat water that is cooled is taken away during dissolving.Evaporimeter 15 and with carrying out solution exchange between the cold space 16 to reduce temperature.Pressurization enters the circulation of the ammonia generator continuation next one to concentrated ammonia solution after the absorption ammonia through solution pump.In generator 13, decomposite ammonia dilute ammonia solution afterwards and return absorber 17 again by the continuation utilization through pressure-reducing valve.
