Definitions
- the present invention relates to a method for optimizing a water spray extinguishing system, which is a water storage device, a pipe system connected to it having nozzles and a propellant to promote the water to the nozzles.
- the extinguishing parameters with thermodynamic and fluid mechanical Methods determined.
- the first step is the development of the flue gas flow and the behavior of water drops emerging from a nozzle in this flue gas stream determined and from the relationships between drop speed, drop size and droplet evaporation become the properties necessary for the extinguishing Water drops calculated.
- the system parameters are pressure, water flow and pipe dimensions so that the desired water drops are created.
- this object is achieved in that the pressure driving the water is selected so that the nozzle pressure required for the required drop size is chosen sets.
- a first preferred embodiment of the method according to the invention is characterized in that that a pressurized gas is used as the blowing agent and the nozzle pressure is set by throttling the driving compressed gas.
- a second preferred embodiment of the method according to the invention is characterized in that that from the size of a given fire and the arrangement of the nozzles for the fire the drop size to be set at the nozzles and from this the nozzle pressure, and that from the nozzle pressure the line diameter and the throttling of the driving Compressed gas is calculated.
- the required nozzle pressure is therefore first calculated and then this nozzle pressure is set by throttling the driving compressed gas.
- throttling the driving compressed gas is due to the phenomenon of critical flow of compressible media the discharge pressure during the extinguishing if possible held constant for a long time. This phenomenon states that the speed in the throttle body cannot be greater than the speed of sound and therefore the driving pressure drop is independent as long as it does not fall below a certain minimum value.
- the invention further relates to a water spray extinguishing system with a water storage device and a line system connected to these with nozzles and with a propellant to convey the water through the pipe system to the nozzles.
- the inventive Extinguishing system is characterized in that a throttle for the reduction of the Pressure of the blowing agent is provided.
- a third preferred embodiment of the extinguishing system according to the invention is thereby characterized in that when the valves are open, the blowing agent flowing through the pressure line relaxed when passing the throttle and reached the state of critical flow, at which the pressure after the throttle assumes an almost constant value.
- a fourth preferred embodiment of the extinguishing system according to the invention is thereby characterized in that the pressure in the gas pressure accumulator is above 100 bar and preferably is 200 bar, and that the pressure in the pressure line after the throttle is below 100 bar and is preferably between 10 and 40 bar.
- this embodiment shows a schematic representation of an extinguishing system according to the invention, in which a blowing agent for the extinguishing water pressurized gas, for example nitrogen, is used.
- a blowing agent for the extinguishing water pressurized gas for example nitrogen
- the extinguishing system consists of a line system 1 with nozzles 2 which are provided for the discharge of extinguishing water in the form of droplets or spray mist.
- the Extinguishing water is stored in containers 3 of a water storage device 4, to which the line system 1 is connected.
- the extinguishing system also assigns a propellant Conveying the water from the storage device 4 to the nozzles 2.
- This blowing agent is a gas pressure accumulator 5.
- the gas pressure accumulator 5 consists of a number of gas high-pressure bottles 6, in which, for example Nitrogen is stored under a pressure of 200 bar.
- the high pressure gas cylinders 6 are connected via valves 7 to a pressure line 8 leading to the water storage device 4.
- the pressure line 8 opens into the individual water tanks 3 and presses when acted upon with high pressure gas the water from the containers 3 into the pipe system 1 and thus to the nozzles 2.
- the pressure line 8 is acted upon by high pressure gas Opening the valves 7, which in the event of a fire by a corresponding signal from a fire alarm 9 or an extinguishing center 10 is triggered, in the latter case the extinguishing center 10 from Fire alarm 9 is activated. It goes without saying that the deletion process is triggered manually possible.
- the pressure line 8 contains an orifice 11 in the area of the gas pressure accumulator 5 through which the delivery pressure in the pressure line 8 and thus also in the line system 1 an optimal nozzle pressure is throttled, for example in the range of about 10 to 40 bar.
- the arrangement of the throttle 11 makes the critical flow phenomenon more compressible Media used by throttling to the delivery pressure as possible during the extinguishing to keep constant.
- the discharge pressure changes only slowly and is guaranteed during the relevant ones Extinguishing or flooding phase an optimal nozzle pressure. That through the throttle 11 caused pressure reduction leads to the fact that when opening the valves 7 in the line system 1 and no dangerous water hammer occurs at the nozzles 2.
- the pipe system 1 and the water tank 3 materials which are not high pressure quality must have.
- the throttle 11 is designed during the installation of the extinguishing system in such a way that it touches the nozzles 2 sets the optimal pressure. This is interpreted in the following way: In a first Step is made up of the dimensions of the space intended for the extinguishing system and a given fire determines the number and arrangement of the required nozzles 2 and Then the development of the fire gas flow, in particular the Ascent rate and temperature of the combustion gases depending on the burn rate, the burning quality, the fire area and the room height. With the help of these values the behavior of water drops after they emerge from the nozzles 2 is then described and the speed and evaporation of the drops are determined as a function of the room height and from this the optimal drop size and drop speed values for deletion certainly.
