Abstract

A fire extinguishing and cooling system for coal cavities and loose areas in a fire district of a coal field comprises a water inlet pipe, a liquid storage tank, a proportioning mixer, a foam generator, a water mist generator, a flow divider, a fire extinguishing agent filling device for ground drilling and an air compressor. After stopping agent or foaming agent in the liquid storage tank and water are quantitatively mixed by the proportioning mixer, the mixture and air provided by the air compressor are mixed in the water mist generator or the foam generator to form flame-retardant water mist or foam, and the flame-retardant mist or the foam is divided to the fire extinguishing agent filling device for ground drilling via the flow divider, the flame-retardant water mist is filled in the coal cavities in the fire district of the coal field, and the foam is filled in the coal loose areas in the fire district of the coal field, so that fire extinguishing and cooling effects are realized. By the aid of the system, the water can be converted into the flame-retardant water mist or the foam, contact areas of the water and the coal cavities and the coal loose areas in the fire district of the coal field are increased, management speed is increased, any external power sources are omitted, and the fire extinguishing and cooling system is simple in operation and convenient and speedy in detachment and movement, and has wide practicality in terms of management of fire districts of coal fields.

Description

Technical field [0001] The present invention involves a kind of coal rock cave and a loose fire extinguishing and cooling system in the coalfield fire area. It is particularly suitable for the rapid fire extinguishing and cooling of coal and fire in the empty cave area of coal fields and loose areas. Background technique [0002] Coal is one of the main energy sources of my country's economic development, accounting for about 70%of the energy production and consumption structure.my country's coal resources are mainly distributed in the northwest and North China. Among them, Xinjiang, Inner Mongolia, Shanxi, Shaanxi, Ningxia, Gansu and other six provinces and regions have proven about 80%of the country's reserves in the country.However, there are currently a large number of coal field fire areas in these areas, such as Xinjiang's current coal field fire area of 9.92 million m 2 , Ningxia's existing coal field fire zone 3.9456 million m 2 wait.Coal field fire not only burns a large...
