Description
Technical field:
The present invention relates to a kind of calcium base CO
2Absorb stove, be used in coal-burning boiler absorbing carbon dioxide discharging occasion.
Background technology:
Global warming mainly is because with CO
2Be that the main a large amount of dischargings of greenhouse gases cause the aggravation of global greenhouse effect to cause, control and minimizing CO
2Discharge capacity have important function for the influence that solves atmosphere greenhouse effects and global warming.China is CO
2Discharging big country, discharge capacity accounts for world CO
21/5 of total emission volumn, wherein most of CO
2Produce by fire coal.In the period of quite growing future, China can not change based on the energy general layout of coal, and the coal consumption amount is with sustainable growth.Be in the main production of energy with fossil fuel, CO
2Discharge capacity account for the caused CO of human comings and goings
2More than 70% of total emission volumn is CO
2Maximum single-point fixed discharge, control and reduce CO in coal-fired the production
2Discharging have significant effect for solving atmosphere greenhouse effects and global warming.Therefore separation of C O from the tail gas of coal-burning boiler
2Be very important, from burning and gas-exhausting, separate and reclaim CO
2Technology become very important.
Have based on this, the applicant makes the present invention.
Summary of the invention:
At above-mentioned technical problem to be solved, main purpose of the present invention provides a kind of reasonable in design, applied widely, low energy consumption and the good calcium base CO of the feature of environmental protection
