A device and a method for capturing carbon dioxide and producing an organic weak acid salt. The device uses ammonia, chloroacetic acid, and hexamethylenetetramine as raw materials to prepare a non-amine carbon dioxide absorbent in the spray evaporation tower, then the non-amine carbon dioxide absorbent is transmitted to an atomizing carbon dioxide absorption tower, and the non-amine carbon dioxide absorbent is dispersed in the atomizing carbon dioxide absorption tower through second atomizing nozzles; a flue gas enters the atomizing carbon dioxide absorption tower, and the flue gas is mixed with the non-amine carbon dioxide absorbent to capture carbon dioxide; the non-amine carbon dioxide absorbent containing the carbon dioxide is transmitted to a carbon dioxide desorption chamber to obtain desorbed carbon dioxide and desorbed non-amine carbon dioxide absorbent; the desorbed non-amine carbon dioxide absorbent is transmitted to the absorbent storage tank for cooling crystallization to obtain the organic weak acid salt.

A self-calibration detection device and a temperature demodulation method oriented to a fiber Raman temperature sensing system. The self-calibration detection device comprises a fiber Raman thermodetector, thermostatic baths, a multi-mode sensing fiber, and a multi-mode reflector. The fiber Raman thermodetector comprises a pulsed laser whose output end is connected to the input end of a WDM. Two output ends of the WDM are respectively connected to input ends of a first and second APDs. Output ends of the first and second APDs are respectively connected to input ends of a first and second LNAs. Output ends of the first and second LNAs are connected to the input end of a data acquisition card whose output end is connected with the input end of a computer. The temperature demodulation method can solve the problems of low temperature measuring accuracy, lower temperature measurement stability and low temperature measurement efficiency.
