Description
Technical field
The utility model relates to flue gas collecting carbonic anhydride technical field, is specifically related to a kind of regenerative system that makes full use of flue gas collecting carbonic anhydride solution.
Background technology
In recent years, the pressure that global warming brings for government and energy enterprise increases rapidly, and a lot of western countries have begun to promote substantial decarburization work.Along with the reinforcement of China's carbon emission amount above the U.S. and the international cry that reduces discharging, power plant's collecting carbonic anhydride probably becomes required technology China's a middle or short term.China is thermal power generation more than 3/4 in the existing power station, does not also have commercial off-the-shelf IGCC power station now.So exploitation is fit to the pure amine absorption process of traditional power plant and catches carbon technique, is the most urgent demand.
The technology of utilizing alkanolamine solution from flue gas, to carry out collecting carbonic anhydride is ripe in chemical industry.But, because that generating plant flue gas has is large-minded, divide characteristics such as force down, it is that energy consumption is high that this technology applies to the maximum problem in power station, steam consumption is big.Reduce consumption, raise the efficiency, the large-scale promotion property that need improve this technology through the system and the subsystem of development of new.
Experimental study finds that for traditional collecting carbonic anhydride technology, solution can consume a large amount of steam in regenerative process; Cause system energy consumption big; And because the regenerator internal pressure is higher, influence carbon dioxide desorb degree, 40% the carbon dioxide of still having an appointment can not get discharging and along with solution entering absorption tower; Cause the solution absorption ability not enough, reduced the capture load of carbon dioxide and the capture steam consumption of unit carbon dioxide on the whole.Simultaneously,, can influence solution and flow, reduce the heat exchange efficiency of heat exchanger, especially can produce cavitation erosion, influence security of system stable operation solution circulation pump ducted owing to containing more carbon dioxide in the solution that leaves regenerator.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists; The purpose of the utility model is to provide a kind of regenerative system that makes full use of flue gas collecting carbonic anhydride solution; This regenerative system can be used for coal-fired power station boiler and chemical field; Have the waste heat that makes full use of actified solution and utilize the lower pressure carbon dioxide more to be prone to the characteristics that discharge, improve the desorption efficiency of carbon dioxide and the regeneration degree of solution, reduce the regeneration energy consumption of unit collecting carbonic anhydride.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of regenerative system that makes full use of flue gas collecting carbonic anhydride solution; Comprise the regenerator 1 that is connected with the absorption tower; With the reboiler 2 that regenerator 1 one side lower parts are connected, this regenerative system also comprises the gas-liquid separator 3 that is connected with regenerator 1 bottom, and said gas-liquid separator 3 bottoms and absorption tower are connected; Top and air pump 4 are conducted, and said air pump 4 is conducted with regenerator 1 opposite side bottom.
Said regenerator 1 is filler or plate tower.
Said reboiler 2 provides thermal source by external steam.
Said gas-liquid separator 3 is for realizing the pressure vessel of gas-liquid separation.
Said air pump 4 is for realizing the pump or the turbine of gas compression.
Compared with prior art, the utlity model has following advantage:
1, since be provided with in regenerator 1 bottom the gas-liquid separator 3 that is connected with regenerator 1 and and the air pump 4 that is conducted of gas-liquid separator 3; Because the effect of air pump 4 makes the pressure of solution in the gas-liquid separator 3 than low in the regenerator 1; The principle that reduces with pressure according to the gas boiling point; Through reducing solution pressure, be reduced in the solubility of uniform temp carbon dioxide gas in solution, improve the desorption efficiency of carbon dioxide and the regeneration degree of solution;
2, on the basis that consumes same external steam, improve the desorption efficiency of carbon dioxide, can reduce the energy consumption of desorb unit's carbon dioxide;
3, reduce the carbon dioxide that contains in the solution that leaves regenerator 1, improved follow-up heat exchanger heat exchange efficiency, reduced the cavitation erosion risk of solution circulation pump.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done more detailed explanation.
Shown in accompanying drawing; A kind of regenerative system that makes full use of flue gas collecting carbonic anhydride solution of the utility model comprises the vertical or horizontal thermosiphon reboiler 2 that the filler that is connected with the absorption tower or plate tower regenerator 1 and regenerator 1 one side lower parts are connected; Reboiler 2 provides thermal source by external steam; With the pressure vessel gas-liquid separator 3 that can realize gas-liquid separation that regenerator 1 bottom is connected, gas-liquid separator 3 bottoms and absorption tower are connected, and top and air pump 4 are conducted; Air pump 4 is for realizing the pump or the turbine of gas compression, and air pump 4 is conducted with regenerator 1 opposite side bottom.
A kind of regenerative system operation principle that makes full use of flue gas collecting carbonic anhydride solution of the utility model is: the solution from behind the absorption tower capture absorbing carbon dioxide gets in the regenerator 1 through regenerator 1 top, and sprays downwards; In regenerator 1 bottom; Solution gets into and returns in the regenerator 1 after reboiler 2 absorbs heat, keeps higher temperature and certain regeneration pressure in the regenerator 1, and the solution after the regeneration leaves regenerator 1 from the bottom; At first get into gas-liquid separator 3; Because the effect of air pump 4, gas-liquid separator 3 internal pressures be than low in the regenerator 1, the further desorb of the carbon dioxide of in regenerator 1, not separating out fully; And and solution separating, through getting into regenerator 1 bottom after air pump 4 superchargings.The solution of separating out fully behind the carbon dioxide leaves from gas-liquid separator 3 bottoms, goes to the absorption tower to continue to capture absorbing carbon dioxide.
