Stopping agent spraying device for coal seam fire extinguishing

Abstract

The invention discloses a stopping agent spraying device for coal seam fire extinguishing. The stopping agent spraying device comprises a stopping agent liquid storage tank, a spraying structure and adetection mechanism; the spraying structure comprises a liquid-state spraying mechanism and an atomizing spraying mechanism; the liquid-state spraying mechanism communicates with the stopping agent liquid storage tank and is used for spraying a liquid-state stopping agent to the coal seam; and the atomizing spraying mechanism communicates with the stopping agent liquid storage tank and is used for spraying a mist stopping agent to the coal seam; and a conversion mechanism is arranged at the joint of the liquid-state spraying mechanism, the atomizing spraying mechanism and the stopping agent liquid outlet pipeline. By arranging the liquid-state spraying mechanism and the atomizing spraying mechanism, a liquid-state or mist stopping agent can be selected for fire extinguishing treatment according to the actual situation of a coal seam, and the selection types of the coal seam stopping agents are increased; and the conversion mechanism is used for converting the state of the stopping agent, the fire extinguishing efficiency of the coal seam is improved, the working intensity of mine workers is reduced, and meanwhile the safety of mine work is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, and in particular relates to a chemical inhibitor spraying device for coal seam fire extinguishing. Background technique [0002] At present, in the process of coal mine production, the problem of coal spontaneous combustion in the working face is extremely serious, which has caused many mine fire accidents. The fire prevention and extinguishing of chemical inhibitors is a new method to prevent and control coal spontaneous combustion which is currently being promoted and applied by the country. However, in the existing sprinkler system, on the one hand, it mainly uses a single-state inhibitor to realize fire extinguishing; chemical agent, which leads to slow fire extinguishing time, resulting in poor fire extinguishing effect and waste of resources; in the existing filling device, it cannot be replenished in time during the fire extinguishing process, and manual inspection is requ...
