Solid oxygen generation device

Abstract

The invention discloses a solid oxygen generation device. The solid oxygen generation device comprises a casing, an ignition assembly and an oxygen containing reactant, wherein the casing is provided with an oxygen outlet, and the oxygen containing reactant is arranged in casing; the ignition assembly is inserted into the casing from the oxygen outlet, one end of the ignition assembly extends outside the oxygen outlet, and the other end of the ignition assembly is connected with the oxygen containing reactant; a gas filtering layer is arranged between the oxygen containing reactant and the oxygen outlet; a thermal insulating protection structure is arranged on the surface of the inner wall of the casing. The solid oxygen generation device does not need external power during using, is convenient to carry and safe and reliable to use and can stably provide the flow larger than 100 L / min within 30s, the oxygen releasing amount is higher than 3,000 L, the oxygen purity is not lower than 99%, the lasting time is not shorter than 30 min, and accordingly, the purpose of emergency first aid is achieved.

Description

technical field [0001] The invention relates to the field of safety emergency technology and equipment, in particular to a solid oxygen generator for rapid oxygen release. Background technique [0002] Oxygen supply device is a necessary equipment to maintain the life of personnel in a confined space. Emergency oxygen supply device should have the characteristics of safety, reliability, portability and rapid oxygen release when personnel are hypoxic. Currently commonly used devices include electrolyzed water oxygen supply equipment, liquid oxygen oxygen supply equipment, chemical oxygen source oxygen supply equipment, etc. Although the above-mentioned equipment can realize the function of releasing oxygen, they all have different disadvantages: for example, the electrolyzed water oxygen supply equipment needs an external power supply, and oxygen production will also produce dangerous gas hydrogen; the liquid oxygen tank oxygen supply device is easy to use, but the storage te...

Problems solved by technology

Although the above-mentioned equipment can realize the oxygen release function, they all have different disadvantages: for example, the oxygen supply equipment for electrolyzed water needs an external power supply, and oxygen production will also produce dangerous gas hydrogen; the oxygen supply device for liquid oxygen tanks is easy to use, but the storage temperature needs to be - Below 183°C, at the same time, its oxygen storage capacity is limited and it is not easy to carry. Oxygen cylinders are high-pressure containers, which are dangerous in storage and transportation. In the superoxide oxygen production technology represented by alkali metals, the agent will deteriorate after absorbing water, resulting in reaction efficiency At the same time, the agent itself has strong oxidizing properties, is corrosive to equipment, and will also cause damage to the human respiratory system
