Strike suffocation energy-saving flame extinguishing device and control method

Abstract

The invention provides a strike suffocation energy-saving flame extinguishing device and a control method, and belongs to the technical field of engine air inlet flame extinguishing. The strike suffocation energy-saving flame extinguishing device comprises a shell, a water mist spraying head, an integrated control device, an anti-explosion water pump, a low-pressure main pipe, a high-pressure mainpipe and a water tank; the shell is internally provided with an air inlet cavity, a flame extinguishing cavity, a water mist cooling cavity and an air outlet cavity; the water mist spraying head is arranged in the flame extinguishing cavity, and the minimum water pressure at the position of the water mist spraying head is 1 MPa; and the integrated control device comprises an oxygen concentrationsensor, a temperature sensor, a controller, an anti-explosion power source connected with the anti-explosion water pump, an anti-explosion electromagnetic directional valve, an anti-explosion electricproportional pressure reducing valve, an anti-explosion electric proportional flow valve and a pressure-compensated valve. By means of the device and the control method, the flame extinguishing efficiency can be improved, the ventilation capacity of inlet air of an engine is not influenced, and solid powder particles carried by the inlet air under the serious work environment can achieve the sediment and filtering effect.

Description

technical field [0001] The invention relates to the technical field of engine intake flame extinguishing, in particular to an impact suffocation energy-saving flame extinguishing device and a control method. Background technique [0002] Explosion-proof rubber-tyred vehicles are the main equipment for trackless auxiliary transportation in coal mines, and their main power source is explosion-proof diesel engines. At present, most of the flame barriers of the air intake system of domestic explosion-proof diesel engines are plate or mesh flame arresters made of metal materials. Although their structure is simple, there are many problems: 1. The ability of metal mesh flame arresters to extinguish flames is limited; 2. 1. Under the harsh working environment, the air containing a small amount of solid particles is likely to cause blockage of the metal plate or mesh flame arrester; 3. The ventilation capacity of the metal plate or mesh flame arrester is poor, which may easily cause...
