Technical Field

Background

The circulating diving breathing apparatus has the characteristics of long underwater working time, good concealment and high gas utilization rate, and is widely applied to technical diving, scientific investigation diving, cave diving and military diving. The working principle of the circulating type scuba is that the gas exhaled by the diver can be inhaled by the carbon dioxide absorbent tank to remove carbon dioxide and then enter the breathing circuit again for breathing by the diver. When the existing diver breathes by using the circulating scuba, carbon dioxide exhaled by the diver is generally absorbed by the carbon dioxide absorbent in the carbon dioxide absorbent tank through the carbon dioxide absorbent tank, and the absorbed carbon dioxide is wasted.

The inventor considers whether the carbon dioxide exhaled by the diver can be changed into valuable, and after research, the inventor proposes a technology which utilizes an oxygen generating agent to convert the carbon dioxide exhaled by the diver into oxygen after chemical reaction, and provides the oxygen for breathing of the diver, and the redundant carbon dioxide can be absorbed by a carbon dioxide absorbent. Based on the above, the inventor has discovered that an oxygen generating agent tank and a carbon dioxide absorbent tank are designed as an integrated structure. Since it is also necessary to know the oxygen production time of the oxygen generator carried in the oxygen generator tank and the absorption time of the carbon dioxide absorbent carried in the carbon dioxide absorbent tank, the present inventors have devised an estimation method of estimating the oxygen production time of the oxygen generator in the oxygen generator tank and the absorption time of the carbon dioxide absorbent in the carbon dioxide absorbent tank.

S22, regarding the uppermost carbon dioxide absorbent: the controller judges whether the temperature average value corresponding to the top of the layer is larger than a second set temperature limit value and smaller than the second set temperature limit value, if yes, the controller indicates that the carbon dioxide agent at the top of the layer and carbon dioxide exhaled by a diver are subjected to chemical reaction to absorb carbon dioxide until the carbon dioxide absorbent at the top is saturated and no longer absorbs carbon dioxide, at the moment, the controller is used as a carbon dioxide absorption time end point of the layer, estimates the carbon dioxide absorption time of the carbon dioxide absorbent based on the carbon dioxide absorption time starting point and the carbon dioxide absorption time end point of the layer, records and stores the carbon dioxide absorption time into a storage, and controls a waterproof display screen to display the carbon dioxide absorption time, the carbon dioxide absorption time starting point and the carbon dioxide absorption time end point of the layer of the carbon dioxide absorbent;

S23, the controller is used for calculating the total carbon dioxide absorption time of all carbon dioxide absorbents in the absorbent chamber based on the carbon dioxide absorption time of each layer of absorbent, and controlling the waterproof display screen to display the total carbon dioxide absorption time, the total carbon dioxide absorption time starting point and the total carbon dioxide absorption time ending point of all the carbon dioxide absorbents in the absorbent chamber;

steps S11-13 are performed in parallel with steps S21-23.

9. The method for estimating a reaction time of a reactant in an integrated reactant tank according to claim 8, wherein an alarm is provided on the oxygen generating agent tank cover;

In step S12, when the controller determines that the average temperature value corresponding to the bottom of the lowest layer of small oxygen generating agent chamber is greater than the first set temperature limit value and less than the first set temperature limit value, the controller controls the alarm to send out a prompt message that the oxygen generating agent is used up;

In step S22, the controller controls the alarm to send out warning information that the carbon dioxide is about to be used up and water is discharged as soon as possible when judging that the average value of the temperatures corresponding to the lower parts of the small cavities of the uppermost absorbent is greater than the second set temperature limit value.
