Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0019] 1.1 Detection device of the present invention

[0020] As shown in Figure 1, the device of the present invention comprises a reactor 1 (about 10 milliliters in volume) and a digital display pressure gauge 2, and the panel of the reactor is provided with a sample inlet 3 and a pressure gauge sensor interface 4, and the sample inlet There is a sealing plug 5 which can be switched on and off, and is used for adding the sample to be tested and injecting the reaction reagent into the reactor 1 . .

[0021] 1.2 Principle of detection method

[0022] 1.2.1 Determination of active oxygen content

[0023] In the closed system, the oxygen generating agent reacts with water to release oxygen and generate pressure. Therefore, it can be judged whether the active oxygen content index of the sample is qualified according to the value of the ...

Abstract

The invention discloses a detecting method of an oxygen-generating agent and the device thereof. The invention comprises a reactor and a pressure gauge. The panel of the reactor is provided with a sample charging nozzle and a pressure gauge sensor connecting nozzle, a sealing plug is provided on the sample charging nozzle, and the sample to be detected and the reagent can be charged into the reactor through the sample charging nozzle. Chemical reaction is taken in the sealing system between the oxygen-generating agent and water, then oxygen is put out and pressure is produced; the active oxygen content index of the sample is determined according to the numerical value increased of the system pressure; and at the same time, the carbon dioxide in the oxygen-generating agent exists in the state of potassium carbonate and calcium carbonate, thick hydrochloric acid is added into the oxygen-generating agent, and carbon dioxide is produced. And the carbon dioxide content index of the sample is determined according to the numerical value increased of the system pressure. The invention has the advantage that the content of active oxygen and carbon dioxide in the oxygen-generating agent can be conveniently grasped. And the invention can be widely used for the detecting of the oxygen-generating agent of the submarine lifesaving device and the danger escaping device.

Description

technical field [0001] The invention relates to a method for detecting an oxygen generating agent and a detection device thereof. Background technique [0002] In order to ensure that the quality of the oxygen generating agent used in underwater escape equipment is qualified, before use, it is necessary to check whether its performance indicators meet the specified standards (that is, the active oxygen content per gram of new oxygen generating agent is not less than 120mL, and the carbon dioxide content is not more than 20 mL) for analysis and detection. [0003] The usual detection method is to use a special oxygen-generating agent detector, but the glass parts of the instrument are easy to damage, so that the oxygen-generating agent cannot be analyzed and detected in time, which brings certain safety hazards to underwater escape training. Contents of the invention [0004] In view of the above problems, the purpose of the present invention is to provide a detection meth...
