Embodiment 1

[0034] A coal-fired power plant boiler discharges flue gas of 170,000 cubic meters per hour, and the carbon dioxide content in the flue gas is 15%. In the three-tower absorption device, 17.5% ammonia solution is used as the absorbent, and the molar ratio of ammonia to carbon dioxide is 1.6. The specific process is:

[0035] The ammonia solution is sprayed by the ammonia material circulation device I (8), II (9), III (10) to the main and auxiliary absorption towers (3) and (4) entering the carbon dioxide absorption system to absorb the carbon dioxide in the flue gas that has been pre-dust removed Afterwards, enter the multifunctional separation device (7) and enter the amino substance circulation device III (10) after separation; the ammonia and dust etc. that are washed by clear water in the cleaning tower enter the amino substance circulation device III (10); The former amino substance storage device (14) replenishes to the amino substance circulation device (10) to continue ...

Embodiment 2

[0037] A coal-fired power plant boiler discharges 485,000 cubic meters of flue gas per hour, and the carbon dioxide content in the flue gas is 14%. In the three-tower absorption device, 20% ammonia solution is used as the absorbent, and the molar ratio of ammonia to carbon dioxide is 1.8. The specific process is:

[0038] The ammonia solution is sprayed by the ammonia material circulation device I (8), II (9), III (10) to the main and auxiliary absorption towers (3) and (4) entering the carbon dioxide absorption system to absorb the carbon dioxide in the flue gas that has been pre-dust removed Afterwards, enter the multifunctional separation device (7) and enter the amino substance circulation device III (10) after separation; the ammonia and dust etc. that are washed by clear water in the cleaning tower enter the amino substance circulation device III (10); The former amino substance storage device (14) replenishes to the amino substance circulation device III (10) to continu...

Embodiment 3

[0040] A coal-fired power station boiler discharges flue gas of 305,000 cubic meters per hour, and the carbon dioxide content in the flue gas is 14%. In the three-tower absorption device, 15% ammonia solution is used as the absorbent, and the molar ratio of ammonia to carbon dioxide is 1.5. The specific process is:

[0041] The ammonia solution is sprayed by the ammonia material circulation device I (8), II (9), III (10) to the main and auxiliary absorption towers (3) and (4) entering the carbon dioxide absorption system to absorb the carbon dioxide in the flue gas that has been pre-dust removed Afterwards, enter the multifunctional separation device (7) and enter the amino substance circulation device III (10) after separation; the ammonia and dust etc. that are washed by clear water in the cleaning tower enter the amino substance circulation device III (10); The former amino substance storage device (14) replenishes to the amino substance circulation device III (10) to conti...

Abstract

The invention discloses a discharge reducing and resourcing method of coal-burning power station flue gas carbon dioxide, which is characterized by the following: adopting amino material as adsorbent; injecting amino material solution as ammonium salt pattern into the flue gas of carbon dioxide adsorbing system after pre-dedusting the tail part of coal-burning stove to reduce 20-95% carbon dioxide in the flue gas; separating and purifying to obtain high-purity carbon oxide; fitting for industrial, chemical, food manufacturing, oil extracting oil displacement and so on; making the escape rate of ammonium in the clean gas discharged by defroster not more than 15mg / Nm3. The invention simplifies the flow path technique with obvious kind and quantity of manufacturing equipment, which has more widely using prospect.

Description

Technical field: [0001] The present invention relates to a coal-fired power plant flue gas carbon dioxide emission reduction and resource utilization technology. The technology is applied to the emission control process of coal-fired power plant tail gas pollutant carbon dioxide, and is suitable for existing and newly built large, medium and small units. Carbon dioxide emission reduction and resource technology transformation and construction projects. Background technique: [0002] Carbon dioxide is a greenhouse gas with the largest emission. Compared with other greenhouse gas emissions, carbon dioxide emissions account for almost 82% of the total greenhouse gas emissions. possibility. This climate change will accelerate the evaporation of water in the soil, which will have a negative impact on the production of rice, wheat, and cotton, resulting in an average 8% reduction in crop yield in my country. In my country's energy structure, coal has always accounted for more th...
