Problems solved by technology

This method has relative advantages in cost, but the process and system equipment are still relatively complicated, requiring high pressure, low temperature and long reaction time, and cannot run continuously
[0008] In the field of cement production worldwide, although there is emphasis on the low-carbon emission reduction of cement enterprises, because it is more difficult to deal with post-combustion flue gas, no specific carbon dioxide capture, sealing and application of cement plant flue gas has been seen so far. research or practice report

Abstract

The invention relates to an absorption-reactivator for continuously trapping carbon dioxide in flue gas. The absorption-reactivator comprises a flue gas CO2 continuous absorption regeneration unit, the flue gas CO2 continuous absorption regeneration unit is formed by a continuous CO2 absorbing tower, a continuous CO2 regeneration tower, a cold / heat exchange device which are connected in series; and the continuous CO2 absorbing tower and the continuous regeneration tower are communicated through the cold / heat exchange device. The absorption-reactivator breakthroughs the equipment technical bottleneck of traditional trapping of CO2 in industrial flue gas, especially that a secondary pollution-free hydrate method for trapping CO2 is difficult to adapt the large-flow continuous trapping, and the invention creatively develops the apparatus for continuously trapping carbon dioxide in flue gas by the hydrate method, the apparatus has the advantages of novel and simple structure as well as easy control, and creates the equipment condition for large-scale continuous trapping of CO2 by a post-combustion method, and especially creates the equipment condition of large-scale continuous trapping of industrial flue gas CO2 by solvent-free or auxiliary agent secondary pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a CO 2 The capture method adopts the hydrate method to continuously capture the carbon dioxide in the flue gas absorption-regenerator. Background technique [0002] Climate change has become one of the issues affecting human survival and development, and industrial emissions of carbon dioxide are considered to be the main cause of climate warming. my country, as the largest developing country in the world, uses coal as its primary energy and fire The secondary energy structure dominated by power generation, with the rapid growth of economic aggregate, the CO of primary energy and secondary energy 2 Emissions are characterized by rapid growth and large volumes. However, the high investment and high capture cost of the current CCS or CCUS technology for carbon emission reduction and climate change have become serious obstacles to the promotion and applic...
