Device and method for quickly purifying fire smoke from mine roadway

Abstract

The invention discloses a device and a method for quickly purifying fire smoke from a mine roadway. The device comprises a plurality of vertically arranged gas suction branch pipes arranged along thelength direction of the mine roadway, a main suction pipe connected with the plurality of vertically arranged gas suction branch pipes, a fan connected with the main suction pipe, and a smoke purification device, wherein a filter screen is arranged at the inlet of the fan; the smoke purification device comprises a smoking mechanism, a first cooling mechanism, a second cooling mechanism, a carbon monoxide purification mechanism and a tail gas absorption mechanism which are sequentially connected; and a smoke hood is arranged at the bottoms of the vertically arranged gas suction branch pipes. The method comprises the following steps: 1, data acquisition; 2, preliminary filtration of the smoke; 3, cooling of the smoke; and 4, smoke purification. According to the invention, the smoke generatedin a fire area in the mine roadway can be extracted and purified in time, so that the life, health and safety of underground workers are guaranteed, and help is provided for subsequent fire extinguishing.

Description

Technical field [0001] The invention belongs to the field of mine tunnel flue gas purification technology, and in particular relates to a rapid purification device and method for mine tunnel fire smoke. Background technique [0002] When a fire occurs in a mine tunnel, a large amount of smoke will be produced. The smoke contains toxic substances such as smoke, CO and a small amount of sulfur dioxide. If measures are not taken in time, the smoke will spread along the tunnel, which will seriously threaten the life safety of underground workers. The subsequent fire extinguishing brings difficulties. In addition, due to the high concentration of smoke and dust, the visibility of the scene is greatly reduced, which makes it difficult to find escape routes, transfer items, find fire points, and put out fires, and hinder rescue and fire fighting. In response to mine fire area flue gas purification, the existing technical means are relatively few. Therefore, it is necessary to design a ...

AI Technical Summary

Problems solved by technology

[0002] When a fire breaks out in a mine roadway, a large amount of smoke will be produced. The smoke gas contains toxic substances such as smoke, CO and a small amount of sulfur dioxide. If measures are not taken in time, the smoke will spread along the roadway, seriously threatening the lives of underground workers. Subsequent firefighting poses difficulties

In addition, due to the high concentration of smoke and dust, the visibility at the scene is greatly reduced, which brings great difficulties to find escape routes, transfer items, find fire points, and extinguish fires, hindering the development of rescue and fire fighting work.

There are relatively few existing technical means in dealing with the purification of smoke in mine fire areas. Therefore, it is necessary to design a device and method for quickly purifying smoke from mine roadway fires, so that the smoke generated in the fire area in the roadway can be recovered in a timely manner. Extraction and purification to ensure the life, health and safety of underground workers, and also provide assistance for subsequent fire fighting
