技术领域technical field
本实用新型涉及二氧化碳回收技术领域，具体是一种烟囱排放气用二氧化碳捕集回收装置。The utility model relates to the technical field of carbon dioxide recovery, in particular to a carbon dioxide capture and recovery device for chimney exhaust gas.
背景技术Background technique
随着全球经济的不断发展，现代化工业社会中使用大量的煤炭、石油、天然气造成的二氧化碳排放量正急剧增加，加之地表森林植被不断遭受破坏，温室效应造成的气候变暖问题迫在眉睫，全球碳排放量再创新高，当很多人对此消息无动于衷时，碳排放增加带来的温室效应正悄然影响着人们的生存环境。病虫害增加、海平面上升、气候反常、沙漠化面积增大，科学家预测，如果地球表面温度按现在的速度继续发展，2050年全球温度将上升2-4摄氏度，这将意味着南北极冰山大幅度融化，海平面上升将导致包括纽约、上海、东京和悉尼等沿海城市和一些岛屿国家消失于人们视野中。With the continuous development of the global economy, the carbon dioxide emissions caused by the use of a large amount of coal, oil, and natural gas in the modern industrial society are increasing sharply. In addition, the surface forest vegetation is constantly being destroyed. The problem of climate warming caused by the greenhouse effect is imminent. Global carbon emissions While many people are indifferent to the news, the greenhouse effect brought about by the increase in carbon emissions is quietly affecting people's living environment. Increased pests and diseases, sea level rise, abnormal climate, and increased desertification area. Scientists predict that if the earth's surface temperature continues to develop at the current rate, the global temperature will rise by 2-4 degrees Celsius in 2050, which will mean that the icebergs in the Arctic and Antarctic will melt substantially. , sea level rise will cause coastal cities including New York, Shanghai, Tokyo and Sydney and some island countries to disappear from people's sight.
二氧化碳是碳和含碳化合物的最终氧化产物，广泛存在于自然界中，其含碳量是现有化石燃料含碳量的10倍。随着煤炭、石油等化石能源逐渐消耗，二氧化碳将成为主要的碳源，而且二氧化碳性质稳定，易于运输和储藏，若能有效利用，其工业前景十分可观，烟囱排放气中含有大量的二氧化碳，而现在烟囱排放气主要采用变压吸附、MEA法回收烟囱排放气中的二氧化碳，变压吸附的主要缺点是投资大、消耗高、回收效率低，MEA法主要的缺点是再生所需的热量大；对热交换设备、吸收塔、洗涤塔等设备腐蚀严重；不适宜从含氧气量较高的烟囱排放气中回收二氧化碳；吸收剂消耗量巨大。Carbon dioxide is the final oxidation product of carbon and carbon-containing compounds, widely exists in nature, and its carbon content is 10 times that of existing fossil fuels. With the gradual consumption of fossil energy such as coal and oil, carbon dioxide will become the main carbon source, and carbon dioxide is stable in nature and easy to transport and store. At present, the chimney exhaust gas mainly adopts pressure swing adsorption and MEA method to recover carbon dioxide in the chimney exhaust gas. The main disadvantages of pressure swing adsorption are large investment, high consumption, and low recovery efficiency. The main disadvantage of MEA method is that the heat required for regeneration is large; Severe corrosion on heat exchange equipment, absorption towers, scrubbers and other equipment; it is not suitable for recovering carbon dioxide from chimney exhaust gas with high oxygen content; the consumption of absorbent is huge.
