Embodiment 1

[0040] Such as figure 1 , Figure 6Shown, the present invention comprises the storage container 1 that has air inlet and powder spraying port and the interior is equipped with superfine dry powder fire extinguishing agent, the ultrafine dry powder spraying device that is connected with described powder spraying port and with described air inlet Sealed connection of high-pressure gas drive. The ultra-fine dry powder spraying device comprises a powder spray tube 4 that is installed on the powder spray port and communicates with the inside of the storage container 1, an ultra-fine dry powder outlet nozzle 5 that is installed on the other end of the powder spray tube 4, and is arranged on the spray tube. Inside the powder pipe 4 and under the pressure-free state, the dry powder spraying sealing diaphragm 2 that automatically and temporarily closes the powder spraying channel in the powder spraying pipe 4 and is arranged behind the outlet of the ultrafine dry powder outlet nozzle ...

Embodiment 2

[0048] Such as Figure 7 As shown, in this embodiment, the difference from Embodiment 1 is that the powerful axial flow fan 6 is arranged in front of the outlet of the superfine dry powder outlet nozzle 5. The powerful axial flow fan 6 "suctions" the superfine dry powder cold aerosol fire extinguishing agent to the distant fire zone. In this embodiment, the rest of the structures, connections and working principles are the same as those in Embodiment 1.

Abstract

The invention discloses an ultrafine dry powder cold gas sol fire extinguishing device which comprises an ultrafine dry powder fire-extinguishing agent storing container, an ultrafine dry powder spray device and a high-pressure gas drive device, wherein the ultrafine dry powder fire-extinguishing agent storing container is provided with a gas inlet and a powder spray opening; the ultrafine dry powder spray device is sealed and connected with the powder spray opening; the high-pressure gas drive device is sealed and connected with the gas inlet; the ultrafine dry powder spray device comprises a powder spray pipe, an ultrafine dry powder outlet nozzle, a dry powder spray sealing membrane which is arranged in the powder spray pipe and a fan which is arranged in the front or the back of the ultrafine dry powder outlet nozzle; and the high-pressure gas drive device comprises a gas storing bottle which is connected with the gas inlet through a gas inlet pipeline, a gas circuit control valve and an inflating and connecting pipe which is inserted into the storing container and is provided with a gas inlet nozzle. The invention has reasonable design, simple structure, low processing and manufacture cost, simple and convenient use and operation, convenient distribution, high fire extinguishing speed, high fire extinguishing efficiency, environmental protection and no pollution, and simultaneously can be effectively suitable for areas needing fire extinguishment, such as wells, roads, cable chutes, tunnels, subways, and the like.

Description

technical field [0001] The invention relates to a coal mine safety production emergency rescue equipment, in particular to an ultra-fine dry powder cold aerosol fire extinguishing device suitable for fire extinguishing processes in underground mines, roadways, cable trenches, tunnels, tunnels, etc., and capable of quickly extinguishing fires. Background technique [0002] For emergency fire extinguishing of underground mines, roadways, cable trenches, tunnels, tunnels, etc., it is mainly divided into fire extinguishing of gobs and scrapped roadways and underground mines, roadways, cable trenches, tunnels, and tunnels used in roadway fire areas or where gas and coal dust occur There are two types of fire extinguishing after an explosion accident. At present, the fire extinguishing methods used mainly include grouting and sand injection, water injection, technical spraying of chemical inhibitors, foam fire extinguishing, equal pressure fire extinguishing, plugging fire extingu...
