Abstract: A method for capturing carbon dioxide includes: spraying an alkaline solution through a first spray structure; temporarily storing a solution, in a first temporary storage structure, and making the solution flow out through the first spray structure; detecting a concentration of hydroxide and/or a concentration of carbonate of the solution, and supplementing one of an alkaline solution and water into the first temporary storage structure according to the concentration of the hydroxide and/or the concentration of the carbonate; and in a case that the concentration of the hydroxide is less than or equal to m and the concentration of the carbonate is n, controlling a first pump body or a third pump body to stop running, so that the solution enters an electrolysis device for an electrolysis. Adopting the present disclosure solves problems in that capture efficiency of carbon dioxide gas and overall energy consumption are relatively difficult to control.

Abstract: The present disclosure provides a carbon dioxide capture method for coupled staged electrolysis/pyrolysis hydrogen production. The method includes: capturing CO2 in a target component by using an alkaline solution and obtaining a carbonate solution; enabling the carbonate solution to be subjected to mild electrolysis, obtaining a hydroxide and H2 at a cathode, obtaining bicarbonate and a mixed gas of O2/CO2 mixed gas at an anode, and absorbing the CO2 from the mixed gas through a small absorption tower to obtain pure oxygen; recycling the hydroxide to serve as a capture agent; and pyrolyzing the bicarbonate to obtain pure CO2. According to the method for cyclically absorbing/releasing the CO2 by using the alkaline solution, a technology for capturing CO2 within a wide concentration range may be provided.

Abstract: Embodiments of the present disclosure provide an image processing method, device and apparatus, an electronic device, a computer-readable storage medium, a computer program product, and a computer program. The method comprises: obtaining a hash value of a pixel of a low-resolution image; finding a filter bank corresponding to the hash value; respectively filtering the regions corresponding to the pixels in the low-resolution image according to multiple filters in the filter bank such that each filter outputs a filtered pixel value; and writing each filtered pixel value into a corresponding coordinate position of a high-resolution image, thereby realizing super-resolution processing of the image and obtaining a high-resolution image. In the present disclosure, since the pixels in the low-resolution image are filtered, the number of pixels filtered is lower, and the processing efficiency is significantly improved.
