The invention discloses a circulating diving breathing apparatus and method for judging the use condition of a carbon dioxide absorbent. The breathing apparatus comprises a carbon dioxide absorbent tank, a first-stage pressure reducer and a channel switching valve, the circulating diving breathing apparatus comprises a flow sensor and a controller, and the flow sensor is arranged on a pipeline between the first-stage pressure reducer and the channel switching valve; the flow sensor detects the accumulated flow value of pure oxygen in the pipeline; based on the relation that carbon dioxide generated in the metabolism process of the diver and consumed oxygen are in direct proportion and are 1, the controller obtains that the generation amount of carbon dioxide generated in the metabolism process of the diver is equal to the accumulated flow value of pure oxygen in the diving process; the controller calculates the amount of carbon dioxide capable of being absorbed by the carbon dioxide absorbent filled in the carbon dioxide absorbent tank as Q1; the controller is used for calculating the carbon dioxide production quality Q2, the controller calculates the ratio of Q2 to Q1, when the ratio reaches a first set threshold value, first alarm information is prompted, and when the ratio reaches a second set threshold value, second alarm information is prompted.

    本发明判断二氧化碳吸收剂使用情况的循环式潜水呼吸器及方法:呼吸器包括二氧化碳吸收剂罐、一级减压器、通路切换阀门,循环式潜水呼吸器包括流量传感器和控制器,流量传感器置于一级减压器和通路切换阀门之间的管路上;流量传感器检测管路中纯氧的累积流量值;控制器基于潜水员代谢过程产生的二氧化碳和消耗的氧成正比且为1的关系,获得潜水员代谢过程产生的二氧化碳产生量=潜水过程中纯氧的累积流量值;控制器计算二氧化碳吸收剂罐中装填的二氧化碳吸收剂能吸收的二氧化碳量为Q1;控制器用于计算二氧化碳产生质量Q2控制器计算Q2/Q1的比值,当比值达到第一设定阈值时提示第一报警信息,当比值达到第二设定阈值时提示第二报警信息。
