Abstract
The invention relates to the field of fire protection safety equipment and in particular relates to a dry powder extinguishment system. The dry powder extinguishment system comprises a pot body and a fixed seat connected with the pot body in a sealed manner, wherein the fixed seat is also provided with a combustion chamber communicated with the inner part of the pot body; the combustion chamber is also connected with an ignition device; a combustion powder column is arranged in the combustion chamber. The combustion chamber communicated with the inner part of the pot body is arranged on the fixed seat. When the ignition device ignites to fire the combustion powder column in the combustion chamber, the combustion powder column is combusted to quickly produce a large amount of gas, and the combustion chamber is communicated with the inner part of the pot body, so that the produced gas enters the pot body from the combustion chamber. As the internal volume of the pot body is limited, when the gas pressure in the pot body is larger than the atmospheric pressure intensity, dry powder stored in the pot body can be pressed out of the pot body to reach a fire position, so that the aim of extinguishment is fulfilled. Thus, the dry powder extinguishment system disclosed by the invention does not need to implement high-pressure storage like that of a conventional dry powder extinguishment device in the prior art.
Description
Technical field
The present invention relates to firefighting security device field, especially relate to powder extinguishing system.
Background technology
Traditional dry powder extinguishing installation generally all comprises a tank body that dry powder is housed, and the shower nozzle being connected with tank body.In tank body, also store inert gas, make the pressure of tank interior be greater than atmospheric pressure.When needs are put out a fire, open shower nozzle, because the pressure in tank body is greater than atmospheric pressure, dry powder is sprayed by shower nozzle under the pressure of inert gas, arrives position on fire, thereby plays the object of fire extinguishing.In this traditional dry powder extinguishing installation, the air pressure in tank body is higher, and the spray volume of dry powder and spouting velocity are also larger, and extinguishing property is also better.But the pressure of the inert gas in tank body is larger, the dry powder extinguishing installation that extinguishing property is better is also higher to the material requirements of manufacture tank body, and cost is also higher, and therefore the ejection two of the dry powder of existing dry powder extinguishing installation and spouting velocity are limited.In order to address this problem, also has at present dry powder extinguishing installation, on the tank body of dry powder, be connected with a gas tank that gases at high pressure are housed being equipped with, the gas tank of high pressure nitrogen is for example housed, when needs are put out a fire, directly, by the gas tank connection of the tank body of dry powder being housed and high pressure nitrogen being housed, the nitrogen in gas tank enters tank body, and the dry powder in tank body is extruded.
But, no matter be traditional dry powder extinguishing installation, or the dry powder extinguishing installation of the gas tank of gases at high pressure is equipped with in existing connection, it is in storage, the gas tank that the tank body of inert gas is housed and gases at high pressure are housed in temperature higher or clashed in easily explode, so these two kinds of dry powder extinguishing installations have caused larger potential safety hazard in the process of storage.
