Harmful gas filter with environment monitoring function

Abstract

The invention provides special equipment for filtering out harmful gas including carbon monoxide, carbon dioxide and hydrogen sulfide from a mine underground refuge chamber and a rescue capsule. The equipment comprises a filter, a sealing butterfly valve, an air exhaust environment monitor and an air power device. According to the equipment, toxic and harmful gas in air inside the refuge chamber and the rescue capsule can be filtered out, the content of the carbon dioxide is reduced to be less than 0.5 percent, and the content of the carbon monoxide is reduced to be less than 0.0024 percent. The equipment has an auxiliary effect on reducing the humidity in the refuge chamber and the rescue capsule. By virtue of the sealing butterfly valve, drugs can be protected from failure after being stored for 3 years; with the equipment, the environment situation can be monitored in real time, and eight monitoring data can be provided; in a combined electric-manual air power mode, a manual fan can be used for filtering out the harmful gas under the condition of no electric energy.

Description

technical field [0001] The invention belongs to underground life-saving equipment in mines, in particular to equipment for filtering out harmful gases such as carbon monoxide, carbon dioxide and hydrogen sulfide for underground refuge chambers and rescue cabins. Background technique [0002] Our country has promoted the use of emergency escape systems of rescue cabins and refuge chambers in mines. An air protection system is installed inside the refuge facility, including devices for oxygen supply and harmful gas removal. The methods for filtering carbon monoxide and carbon dioxide devices in the existing underground rescue cabins and refuge chambers mostly use the medicines (carbon monoxide oxidation catalyst, desiccant, calcium hydroxide absorbing carbon dioxide, etc.) that filter harmful gases to be placed in packaging barrels (bags). Internal storage, spare. When an underground accident occurs, the miner escapes to the refuge chamber, opens the filtering device, puts t...

AI Technical Summary

Problems solved by technology

There are obvious deficiencies in the above methods. Underground miners are not professional technicians, and they have little knowledge of the characteristics of drugs. If they cannot be used correctly, they may cause drug failure or performance degradation, and cannot achieve the expected effect.
