Colloid foam fire preventing and extinguishing equipment

Abstract

The invention discloses colloid foam fire preventing and extinguishing equipment and a use method thereof. The equipment comprises a water storage tank, a mother liquor storage tank, a coagulant storage tank, a foaming agent storage tank, a vortex air pump, a self-priming pump, a multi-flow mixing device, a carbon monoxide sensor, a flame sensor, a camera, an alarm and a PLC intelligent control system; the multi-flow mixing device comprises staggered baffles, double helical ribbons and a net-shaped foaming core; the storage tanks are connected with the self-priming pump through spring pipes, and the other port of the self-priming pump is connected with the multi-flow mixing device; the outlet end of the multi-flow mixing device is connected with a flow dividing device, and colloid foam is divided through an electromagnetic valve at the tail end of the flow dividing device to cover different ignition subareas; and the PLC intelligent control system can realize dynamic adjustment of key process parameters according to working conditions and automatically match to the optimal raw material ratio of the colloid foam. The colloid foam fire preventing and extinguishing equipment and the use method thereof are high in automation degree, efficient fire extinguishing is achieved through efficient preparation of the colloid foam and intelligent control over the fire preventing and extinguishing process, and effective treatment of mine fire disasters can be achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine fire prevention and extinguishing, in particular to colloidal foam fire prevention equipment. Background technique [0002] Coal spontaneous combustion is one of the main disasters in mines in my country, which seriously threatens the safe production of coal mines. According to statistics, among the key state-owned coal mines in our country, mines prone to coal spontaneous combustion account for 56% of the total, and fires caused by coal spontaneous combustion account for 90% to 94% of the total number of mine fires. Spontaneous combustion of coal has frozen a large amount of coal resources, disrupted reasonable deployment and mining sequence, and brought huge economic losses and serious accident hazards to mines. [0003] Colloidal foam is a mixed system in which gas is uniformly dispersed in solid colloid. After foaming, the coagulant in the foam wall reacts with the polymer solution to form ...
