Abstract

The invention discloses a fire prevention and extinguishing system and a fire extinguishing method thereof, and belongs to the field of fire prevention and extinguishing. The fire prevention and extinguishing system comprises an air compressor, a nitrogen making machine and a nitrogen cooling device, wherein an outlet of the air compressor is connected with an inlet of the nitrogen making machinethrough a pipeline; an outlet of the nitrogen making machine is connected with an inlet of the nitrogen cooling device through a pipeline; and the inlet of the nitrogen cooling device is connected toa fire prevention area through a pipeline. The temperature of an underground coal seam or a goaf is monitored by a temperature sensor buried in the underground coal seam or the goaf, when the temperature reaches an alarm temperature, the temperature sensor sends out an alarm signal, at the moment, field personnel or a dispatching center immediately make a response to transfer fire extinguishing equipment and open fire prevention and extinguishing equipment and pipeline valves (including the air compressor, the nitrogen making machine, the nitrogen cooling device and a district pipeline valve),low-temperature nitrogen is injected into a pipe network, and the fire prevention and extinguishing effect is rapidly achieved.

Description

technical field [0001] The invention relates to a fire extinguishing system and a fire extinguishing method thereof, belonging to the field of fire extinguishing. Background technique [0002] The fire prevention and extinguishing of coal fields or coal mines is mainly used in coal fields with thick coal seams, shallow burial, widespread outcrops, strong weathering and oxidation, and underground coal mine gobs. It is of great significance to control the fire in coal mine area. [0003] For coalfield or coal mine fire problem, there are two kinds of solutions at present. Firstly, the traditional method of injecting water and loess mud into the fire source is adopted; secondly, liquid nitrogen or liquid carbon dioxide is used to prevent and extinguish the fire in the goaf of the coal mine. This method has great limitations and the cost of firefighting is very high. Expensive and poor applicability. Contents of the invention [0004] The invention provides a fire extinguis...
