A protection and purification system for mine oxygen candles

Abstract

The invention aims to provide a mining oxygen candle protection and purification system. The mining oxygen candle protection and purification system is capable of guaranteeing air quality and serving as protection of air quality, heat transfer, purification, noise reduction and protection and is used for solving the problems of high temperature and dust generated during oxygen supply of an oxygen candle and removing odor ingredients contained in an oxygen candle. The mining oxygen candle protection and purification system is characterized by at least comprising a cylinder body, a gas collection changeover mechanism, a heat exchanger, a filter, a top cover, an oxygen candle generator and a housing protection member, wherein the cylinder body is an inner-outer double-layer body, heat-insulation and sound-insulation materials are filled between an inner body and an outer body, the oxygen candle generator is placed in the inner cavity of the inner-outer double-layer body, and the gas collection changeover mechanism is buckled on an oxygen candle gas outlet of the oxygen candle generator; and the heat exchanger and the filter are respectively arranged at the left side and the right side of the oxygen candle generator in the cylinder body, the heat exchanger and the filter are connected through a connecting pipe at the bottom of the inner cavity of the cylinder body, and the gas collection changeover mechanism is communicated with the heat exchanger through a rotating assembly.

Description

technical field [0001] The invention belongs to the technical field of air quality control and purification. The invention relates to a protection and purification system for an oxygen candle used in mines, in particular to a device with functions of oxygen candle gas purification, heat exchange and protection. Background technique [0002] After a mine accident, the proportion of instant casualties is very small, most of which are caused by being trapped underground and unable to escape. Therefore, all countries have vigorously built mine rescue cabin facilities to create a safe space for miners to wait for rescue after a mine accident occurs. Domestic research on mining rescue chambers started late, lacking corresponding experience and standards, and the core difficulties include the removal of harmful gases, oxygen supply and other survival guarantees in addition to shell requirements. Contents of the invention [0003] The purpose of the present invention is to provid...
