Abstract

The invention discloses a combustion and explosion suppression system with automatic water curtain, comprising a sensor, a control unit, a water supplying device, a water curtain device and a fast triggering device, the sensor is electrically connected with the control unit, a connecting channel is arranged on the fast triggering device, two ends of the connecting channel are respectively communicated with the water supplying device and the water curtain device; a movable opening device is arranged on the connecting channel and is electrically connected with the control device; the water curtain device comprises at least one water curtain ring, a plurality of injection heads are uniformly arranged on the water curtain ring, and an injection water curtain is formed when in water-spraying, and a plurality of water curtain rings form one water curtain band when in water-spraying, so as to realize to suppress gas or gas dust explosion and spreading by adopting water mist in a coal mine, the reaction speed is rapid, the structure is compact and the manufacturing cost is low, thereby having good combustion an explosion suppression effect, being widely applied to industries such as coal mines, petroleum and chemical industry and powerfully promoting the development of explosion insulation (suppression) in our country.

Description

technical field [0001] The invention relates to an automatic water curtain flame suppression and explosion suppression system. Background technique [0002] "Safety first, prevention first" is a basic national policy of our country and a criterion that all walks of life should abide by. Coal mine safety production is the basis and guarantee for the sustainable development of coal economy. Coal mine explosion protection is an important link in coal mine safety production work. [0003] Because water is simple, convenient, and abundant in resources as an anti-explosion medium, the technology of water curtain anti-explosion suppression is gradually attracting people's attention. But at present, it can only be used in ordinary fields such as dilution and dust removal. In the field of explosion prevention and explosion suppression in coal mines, in view of the rapidity and particularity required for explosion protection, there is no formed mine water curtain flame suppression an...
