Abstract

The invention discloses a potassium superoxide air regenerating device for emergent risk avoiding under coal mines, which comprises a device main body, wherein the device main body adopts a hollow cavity structure; the device main body comprises an air inlet area, a reaction area and an air discharge area from the bottom up sequentially; a lower air permeable diaphragm is arranged between the air inlet area and the reaction area; the reaction area is divided into an upper cavity, a middle cavity and a lower cavity; middle air permeable diaphragms are arranged between the three cavities; and each of the upper cavity, the middle cavity and the lower cavity is provided with a potassium superoxide reactor inside. The potassium superoxide air regenerating device is perfect and reasonable in structure, convenient in use and easy to maintain; the device requires no power when working; no substance harmful to human and the environment is generated during the working process and after the reaction is terminated; and while CO2 is eliminated, harmful gases such as CH4, CO, H2S, SO2, NOX and the like are absorbed and cleansed. The potassium superoxide air regenerating device provided by the invention is controllable and can be used for continuously supplying oxygen to airtight space.

Description

technical field [0001] The invention relates to an air regeneration device, in particular to a potassium superoxide air regeneration device used for emergency avoidance in coal mines. Background technique [0002] The "six major systems" for coal mine safety avoidance include detection and monitoring system, underground personnel positioning system, underground emergency avoidance system, mine pressure wind self-rescue system, mine water supply rescue system and mine communication system. Among them, the coal mine emergency avoidance system is the key work in the construction of the "six major systems" of safety avoidance. Coal mine emergency avoidance system refers to an organic whole composed of facilities, equipment and measures to provide life support for people in distress in case of emergency in coal mine. In the past two years, coal mining enterprises across the country have vigorously promoted the construction of "six major systems" for underground safety and risk a...
