Description

Fire extinguishing equipment

The present invention relates to a fire extinguishing facility in a space, the same method being used to produce fire extinguishing fluid in the form of finely divided mists with large penetration capabilities and to create a simultaneous suction state near the spray head. With a spray head.

Such facilities are known from WO 92/20453, WO 92/22353 and WO 94/16771. These known plants have proven to be very good at extinguishing. In order to prevent the droplet size of the extinguishing liquid from becoming too large, an apparatus is disclosed in WO 94/08659 in which gas is mixed into the extinguishing liquid in the plant. As a result of the gas mixing, it is possible to keep the droplet size relatively small while emptying the hydraulic accumulator.

Some rooms, like rooms for machines such as computers, include bundles of electrical cables, as well as expensive machines, and cause great losses in the event of a fire. Electrical cables generally have a plastic envelope, such as PVC. If a fire breaks out in such a room and these cables catch fire, toxic smoke is generated, which is not only dangerous to humans but also destroys sensitive machines such as computers. Facilities known to extinguish such fires are not capable of rapid extinguishing with a small amount of water. The use of other media for extinguishing, not water-based extinguishing fluids, for example halogens, generates chemicals that are harmful to the environment. For this reason, it is more preferable to use a digestive fluid based on water. It is important that the amount of water used to extinguish a fire is important because the loss due to water can be reduced.

The present invention relates to a new plant, which preferably has a simple structure and, for example, very effectively extinguishes a fire in a space such as a room, so that the amount of extinguishing liquid used to purify smoke gas and smoke and simultaneously use it. It is a facility that can be reduced.

For this purpose, the installation according to the invention is mainly characterized by a spray head arranged in a pipe having a suction opening at a distance of 1 m to 10 m from the floor horizontal plane of the space and a spray opening near the floor horizontal plane, The spray head is arranged to spray in the direction of the spray opening from the suction opening so that suction occurs in the suction opening.

In order to obtain a better effect in a larger space, the pipe constitutes a part of the pipe system consisting of a plurality of spray openings and a plurality of intake openings for spraying digestive fluid at least along the floor from the pipe system in the form of fog. Accordingly, the pipe system further comprises an intermediate pipe section connecting the first extended pipe section and the second extended pipe section and the first extended pipe section and the second extended pipe section, whereby the spray opening is the second extended pipe. The section is installed in its longitudinal direction, the suction opening is installed in its longitudinal direction in the first extended pipe section, the second extended pipe section is placed near the floor horizontal plane of the room and the first extended pipe section is 1 m above the floor horizontal plane. It is placed at a distance of 10m.

In large spaces, the facility has another pipe system arranged at a distance from the pipe system so that the pipe system is placed near the opposite wall of the space. Smoke is the result of effective inhalation without the mixing of smoke from space. For effective smoke intake and fire extinguishing in the subfloor of the room, the facility further comprises a pipe net disposed on the subfloor, which is thus arranged in the pipe net and at least one spray head for spraying extinguishing fluid into the pipe net in the form of a mist. Whereby the pipe net has a spray opening for spraying fog out of the pipe net and a suction opening for sucking smoke into the pipe net and for generating a flow of digestion fluid from the spray opening toward the suction opening. And an intermediate pipe portion connecting the first extended pipe portion and the second extended pipe portion, and the first extended pipe portion and the second extended pipe portion, whereby the first extended pipe portion is at least essentially a second extended pipe portion; Directed in parallel, the spray opening and the suction opening are arranged in the pipe portion extending in the longitudinal direction of the extended pipe portion.

More preferred embodiments of the invention are set forth in the appended claims 2 to 19.

The great advantage of this installation according to the invention is that the fire can be extinguished with simple equipment and at the same time the smoke is effectively cleaned. The plant can also be extinguished in an "environmentally friendly" way by using a very small amount of extinguishing fluid, which causes minimal material loss.

Hereinafter, the present invention will be described with reference to the accompanying drawings in more detail.

3 is a view showing the second in detail,

4 to 6 are drawings showing details of the present invention as another solution.

(Example)

In FIG. 1, reference numeral 100 denotes a room equipped with an extinguishing facility in accordance with the present invention. The room 100 shown is a room designed for computers 101 and 102 and having openings 103-105 as subfloors 23 of the room. However, this room can in principle be any kind of room. Subfloor 23 includes many cables (not shown) for computers 101 and 102 and other machines (not shown). Openings 103-105 are designed for cables that are connected to computers 101 and 102, and supply cooling air to the computers. The invention is particularly suitable for use where there are expensive machines in the room which can be damaged by smoke and / or water. Reference numerals 200 and 300 denote thermal sensing sprinklers installed near the ceiling of the room 100. These sprinklers are rather a type capable of producing a digestive fluid in the form of finely divided mists with large penetrating or propulsive forces and simultaneous inhalation near the spray head. Because of its ability to penetrate, extinguishing fluid can reach the site of the fire. Such sprinklers are disclosed in WO 92/20453, WO 92/22353, and WO 94/16771.

This installation consists of two rectangular pipe systems 3a ', 3b' arranged at a distance from each other on the subfloor 23 at the end wall of the room 100, and is of the same type of sprayer as sprinkler 200 and 300. Heads 1a ', 2a', 1b ', 2b' are arranged in the pipe system. In other words, the spray head under high pressure is capable of producing extinguishing liquid in the form of finely divided mists having a large penetrating ability and simultaneously inhaling near the spray head. Spray heads 1a ', 2a', 1b ', 2b' are of the types described in International Publications WO 92/20453, WO 92/22353 and WO 94/16771.

The pipe system 3a 'connects the first extended pipe section 910a', the second extended pipe section 811a 'and the first and second extended pipe sections and respectively spray heads 1a' and 2a 'therein. Consists of intermediate pipe sections 12a 'and 13a' which are arranged. The second extended pipe section 811a 'may have several, for example three to ten spray openings 45a', and the first extended pipe section 910a 'may have several, for example three to ten suction openings. (67a '). The spray opening 45a 'is disposed in the longitudinal direction of the pipe section 811a', and the suction opening 67a 'is disposed in the longitudinal direction of the pipe section 910a'. The function of the suction opening 67a 'is to suck smoke into the pipe net 3a'.

The pipe section 811a 'is disposed adjacent to the floor plane 24 and sprays the fog of the extinguishing fluid essentially in the floor direction. Pipe section 910a ′ is disposed at a distance of about 3 m above the floor horizontal surface 24. The distance will of course vary depending on the application. A distance between about 1 m and 5 m between pipe sections 811a 'and 910a' produces good results in most of the practical applications that occur, but if the room is very high, this distance can reach about 10 m. Pipe sections 910a 'and 811a' are essentially disposed in the same plane across the floor plane 24.

Pipe sections 811a ', 910a' are made of plastic and may have a diameter of, for example, 100mm to 150mm. The diameter of the spray opening or the suction opening is preferably 5 mm to 40 mm.

The pipe system 3b 'is made like a pipe system 3a' and is arranged with respect to the wall and floor horizontal surfaces 24 of the room as if the pipe system 3a 'is arranged on the wall and floor horizontal surfaces of the room. Corresponding parts are denoted by corresponding reference numerals, except that "a" is replaced by "b" in the reference numeral. The pipe system 3b 'acts in the same way as the pipe system 3a'.

A rectangular pipe net, generally indicated by the reference 3, is arranged in the subflow 23 of the room 100. The upper horizontal plane 24 of the subfloor is indicated by a dashed line. Two spray heads 1, 2 of the same type as the spray heads 1a ', 2a', 1b ', 2b' are arranged in the pipe net 3.

The pipe net 3 has a first extended pipe portion 910 and a second extended pipe portion 811. The pipe portion 910 is originally arranged in the same plane as the pipe sections 910a 'and 811a', and the pipe portion 811 is arranged in the same plane as the original pipe sections 910b 'and 811b'. The diameters of the pipe portions 910, 811 are for example 100 mm to 150 mm, and they are made of plastic. The pipe parts 910, 811 are connected at their ends to the first intermediate pipe part 12 on which the spray head 1 is arranged and to the second intermediate pipe part 13 on which the spray head 2 is arranged. The spray heads 1 and 2 are arranged in the center of the pipe portions 12 and 13, respectively, but it is also conceivable to be located elsewhere in the pipe net 3. Spray heads 1 and 2 are arranged to be sprayed in the opposite direction, with spray head 1 being sprayed towards pipe portion 811, while spray head 2 is sprayed towards pipe portion 910. Lose. The first pipe portion 910 has four spray openings 5 and four suction openings 6. The spray opening 5 in the pipe portion 910 is separated from the suction opening 6 by the plug 106. The second pipe part 811 also has four spray openings 4, four suction openings 7, and a plug 107 accordingly. The spray opening 4 is arranged so as to spray the extinguishing liquid toward the suction opening 6. The spray opening 5 is arranged to spray the extinguishing liquid toward the intake opening 7. The diameters of the spray openings 4, 5 and the suction openings 6, 7 are preferably 5 mm to 40 mm, depending, for example, on their application and the number of holes 4 to 7.

The driving source for supplying the extinguishing liquid to the sprinkler 200, 300, the spray heads 1a ', 2a', 1b ', 2b', and the spray heads 1, 2 is denoted by the reference numeral 14, respectively. And a drive unit composed of hydraulic accumulators 15 and 15 'consisting of three pressure containers 16' having a liter capacity and two pressure containers 16a and 16b each having a 10 liter capacity. The pressure containers 16 ', 16a, 16b contain a liquid based on water, i.e., a digestive fluid consisting of with or without additives in water. The pressure container 16 'is filled with approximately 80% before emptying the container or starting extinguishing. The number and size of pressure containers varies depending on their application and the size of the room 100. For large rooms, pressure containers usually require large capacity. The capacity of the pressure containers 16a, 16b will be, for example, half the size of a small room.

50 liters of condensate from the sprinkler 200, 300, the spray heads 1a ', 2b', and the pressure containers 16 ', 16a, 16b which supply the spray heads 1, 2 through the conduit 108, respectively. Is connected to a gas container 21 having a capacity of. Each of the rising tubes 17 'is disposed in the pressure container 16'. The capacity of the gas container 21 is selected based on the volume of the room 100 and other factors. The gas is nitrogen gas at a pressure of 200 bar. Other pressure gas vessels 21 can be used: the pressure is typically from 100 bar to 300 bar before the start of extinguishing. The advantage of using nitrogen is that the digestive fluid can be properly weighted so that the liquid can initially settle on the floor, but later the gas content of the digestive fluid rises, thus reducing the oxygen content in the room 100, Fire is extinguished or at least controlled. In place of nitrogen gas, other incombustible gases such as argon or carbon dioxide can be used.

Reference numeral 115, referring to FIG. 2, prevents the medium from flowing into the rightmost pressure container 16 'via the rising tube 17' of the two pressure containers 16 'on the left. The reverse flow represents a non-return valve that allows.

2 shows the drive unit 14 in more detail. 3 shows details of FIG. The lifting tube 17 'of the pressure container 16' has three lateral openings 18 'at the bottom such that about 70% of the lifting tube is above the lateral opening and about 30% is below the opening. . At the bottom of the riser tube 17 ', there is a supply opening 19'.

3 is an enlarged view of the lower portion of the riser tube 17 ', and the lower portion of the riser tube 17' is shown to be contracted by the throttle 20 '. Throttle 20 'is formed below the riser tube 17' under the lateral opening 18 'of the riser tube 17'. The throttle 20 'is formed by the contraction of the rise tube 17'. The shrinkage forms an opening with a diameter d 2 = 0.5 mm, while the ordinary diameter d 1 of the riser tube 17 ′ generally ranges from 8 mm to 15 mm. The throttle 20 'preferably has a diameter of d2 = 0.2 mm to 4 mm, most preferably 0.3 mm to 2 mm. Selection of the diameter d2 of the throttle 20 'includes the type of spray heads 200, 300, 1a', 2a ', 2b', the number of spray heads, the pushing pressure of the gas container 21, the type of gas, It depends on many factors such as the diameter d1 of the riser tube 17 'and the size and number of the lateral openings 18' and the intended use of this installation, ie the type of fire extinguishing.

The pressure containers 16a and 16b have gas supply pipes 120a and 120b. This allows their contents to be connected to a conduit 108 to supply gas from the gas container 21 to the pressure container.

Reference numeral 122 denotes a non-return valve that prevents fluid from flowing from the pressure container 16b to the gas container 21 or the pressure container 16a.

Before use, ie before the start of extinguishing, the pressure container 16a is filled with water. The outlet 121a of the gas supply pipe 120a is disposed at a sufficiently long distance, for example, about 20 to 30 centimeters from the opening 130a at the bottom of the pressure container 16a. Water is passed through the opening 130a out of the pressure container to the external feed pipe 110 which is led to the spray heads 1 and 2. It is believed that a minimum distance of at least about 4 cm will be required. This distance is required so that gas does not flow into the opening 130a before the water in the pressure container 16a is emptied. A duct leading to the external feed pipe 110 leading to the spray heads 1 and 2 is indicated by 131a.

Referring to FIG. 2, the pressure container 16b is filled with about 80% water before being emptied. In the gas space of the upper portion of the pressure container 16b, nitrogen gas is filled at high pressure from the gas container 21 so that pressure forms, for example, 140 bar before the emptying of the accumulator 15 starts. The pressure container 16b has a rising tube 17 extending downward from the pressure container and leading to the outer supply pipe 110. In connection with the lift tube 17, a throttle 121 is disposed. The function of the throttle 121 is to provide flow resistance, which is large enough for the water to allow the pressure container 16a to empty the water for the first time, after which the emptying of the pressure container 16b through the throttle can begin.

The pressure container 16a is used to purify the smoke and smoke gas, and the pressure container 16b provides an extremely finely divided mist of water droplets and nitrogen gas.

The installation according to FIG. 1 is operated by means of signals from a smoke detector 111 located near the ceiling height of the room 100. This signal causes the opening of the solenoid valve 109 located between the gas container 21 and the pressure containers 16 ', 16a', 16b '. It is conceivable that the sprinkler 200,300 of this installation is of a pressure balanced type, but optionally released by heat, for example as disclosed in publications WO 92/158370 and WO 94/1677. When the valve 109 is opened by a signal, nitrogen gas enters the pressure containers 16 ', 16b, in which an initial pressure is formed, for example, 140 bar. This pressure is created in the gas space of the pressure containers 16 ', 16b in the upper portion of the pressure container. Referring to FIG. 2, the gas spaces in the pressure containers 16 'and 16b make up about 20% of the volume of the pressure container. Nitrogen acts as a propellant gas that drives water out of the pressure containers 16 'and 16a. Due to the fact that the pressure container 16a does not have a rising tube for water, the water does not freeze, but instead, the pressure container 16a actively empties the water by the pressure of the gas container 21. After the pressure container 16a empties the water, the water flows from the pressure container 16b and at the same time the gas flows into the external supply pipe 110 via the opening 130a, by the pressure of the pressure container, the throttle 121. ) Flows through the duct 131a and mixes with the gas. The ratio of the amount of gas coming out of the pressure container 16a and the amount of water coming out of the pressure container 16b is, for example, 300: 1, and a range of 100: 1 to 500: 1 is appropriate. This produces very good fog from the spray heads 1, 2. The gas pressure in the upper portion of the pressure container 16b causes water to pour into the external supply pipe 110 for the first time.

At the same time as the pressure container 16a is emptied (or slightly delayed in time), the water is emptied from the supply opening 19 'or the lateral opening 18' of the rising tube 17 'as the pressure container 16' is emptied. Flows through). When the pressure container 16 'is emptied, its water level goes down, as a result of which the volume of the gas space of the pressure container for the gas increases. The ratio of gas / water present in the riser tube 17 'is determined based on the position of the water height in the pressure container 16'. Initially, the lateral opening 18 'and the supply opening 19' supply only water through the throttle 20 to the riser tube 17 '. The gas should not be mixed with the extinguishing fluid at the beginning of the extinguishment, and in this regard, the initially required suction at the intake openings 6, 7, 67a ', 67b' is not achieved. Water is used to inhale and purify smoke gas or smoke, and at the same time the fire is cooled. When the water level reaches the height of the lateral opening 18 ', for example when 1 to 3 liters of water is sprinkled from the pressure container 16', the mixing of nitrogen gas in the water causes the nitrogen gas to laterally It begins by flowing through the opening 18 '. The gas pressure then drops considerably to values below 140 bar. Since the gas pressure in the pressure container 16 ′ has dropped considerably, the amount of gas required to obtain droplets, for example 10 to 20 μm, is relatively large. The size of the droplets increases with increasing pressure if the remaining parameters do not change. Despite the fact that the gas is mixed in the digestive fluid, smaller droplets of higher velocity are obtained, and the intake openings 6, 7, 67a ', 67b' can be operated in the desired manner, and at the onset of evolution Because of the strong initial suction that occurs, a flow of media thus occurs from the spray openings 4, 5, 45a ', 45b' to the suction openings 6, 7, 67a ', 67b'. Emptying the pressure container 16 'continues until the pressure container is completely empty if the valves 109 and 160 are not closed.

Referring to FIG. 3, as a result of the throttle 20 ', a relatively large pressure difference p1-p2 is formed in the lateral opening 18', from the outer region of the lift tube 17 'to the inner region. This pressure difference can be trimmed, for example, to 50 bar, and when the water level of the pressure container 16 'sinks to a height below the lateral opening 18', the nitrogen gas is effectively passed through the opening 18 '. Let it flow Due to the fact that gas can effectively flow into the lateral opening 18 ', as a result, the droplet size of the spray emitted from the spray heads 1a', 2a ', 1b', 2b ', 200, 300 is very small, For example, it can be obtained at the last stage of evolution, from 10 to 20 μm or smaller than 10 μm. Since gas mixing is effective, a small amount of water is sufficient.

The lateral opening may of course be arranged at other heights of the riser tube 17 '. Through the height and size of the lateral opening, it is possible to obtain the desired droplet size and concentration of the digestive fluid during the emptying process. This places the throttle below the lowest lateral opening, whereby a large pressure difference is obtained at all lateral openings, which is advantageous for attempting to mix as much gas as possible into the liquid. However, it is conceivable that the lateral opening can be disposed above or below the throttle 20 '. It is important, however, that the throttle 20 'is arranged below the highest lateral opening, whereby a large pressure difference is at least obtained in this lateral opening, and when the water level sinks to the height of this opening, Flow gas through.

If the throttle 20 'is formed by the aperture with a diameter d2 sufficiently small relative to the diameter of the lateral opening 18', the pressure difference p1-p2 becomes very large and liquid can flow through the lateral opening. The diameter of the lateral opening is satisfactorily between 0.5 mm and 5 mm, most preferably between 1 mm and 3 mm. According to the embodiment of FIG. 1, the lateral opening has a diameter of 2 mm.

The rising tube 17 'in the pressure container 16' does not always require a lateral opening 18 'and a throttle 20'.

The pipe net 3 forms two streams of media swept in opposite directions in the subfloor 23 along the floor, and by the pipe systems 3a ', 3b', smoke intake in the upper part of the room 100. This also happens. This can be explained by:

When the apparatus of FIG. 1 is operated after the smoke detector 111 sends a signal to the drive unit 14, the spray heads 200, 300, 1, 2, 1a ', 2a', 1b ', 2b' are not misted. Start spraying the same liquid spray for the first time. The spray heads 1a ', 2a', 1b ', 2b' are sprayed along the middle of the pipe systems 3a 'and 3b', so that they are first purified (air purified from smoke or smoke) and later nitrogen gas. Water fog including the is discharged from the spray opening (45a ', 45b'). The spray heads 1, 2 spray along the middle portions 12, 13 of the pipe system 3, so that initially purified air is sprayed from the spray openings 4, 5, and later mist is sprayed ( Sprinkled from 4,5). At the same time as the spray heads 1a ', 2a', 1b ', 2b', 1, 2 are sprayed, they make a strong suction behind them, the suction being respectively at the suction openings 67a ', 67b', 6, 7 Occurs. Smoke is sucked into the intake opening and absorbed by the mist-like spray from the spray head. This absorbed smoke is absorbed into the extinguishing liquid of the pipe systems 3a 'and 3b' and the pipe net 3. As a result of the fact that the pipe systems 3a ', 3b' and the pipe net 3 inhale smoke or smoke gas, the air in the room 100 is effectively purified from smoke or smoke gas, and any damage or harmful Does not cause

In order to collect the smoke residues, the intermediate pipe portions 12, 13 also have a concave space (not shown) in the other straight pipe portion. This space is arranged on the pressure side of the spray heads 1, 2. The pipe systems 3a ', 3b' may have a collection vessel at the bottom, shown in FIGS. 5 and 6 and indicated by reference numerals 200 "'and 200" ".

When the pressure containers 16a, 16b, 16 'emptied the digestive fluid, the room 100 and the subfloor 23 are purged from smoke and smoke gas, the subfloor is filled with a digestive fluid mist containing nitrogen gas, The room, especially its lower part, is full of misty sprays that settle towards the floor after a while. Due to the water in the digestive fluid, the digestive fluid fog in the subfloor 23 and the digestive fluid fog near the floor height 24 are relatively heavy, and the digestive fluid fog sprayed onto the subfloor 23 and the digestive fluid fog on the floor are initially subfloor. They remain at the floor level of the room and the room, and extinguish the fire that smokes. Typically, after a few minutes, the water sinks slowly and the nitrogen gas frees from the water and begins to rise into the room. This is because it is lighter than air. As nitrogen gas rises, it evolves all possible fires that still smoke inside the room on the way up. Nitrogen gas enters the computer (101,102) because of the "chimney effect" and nitrogen gas rises up the computer and functions like a chimney. Nitrogen gas flows into the computers 101 and 102 through the opening 103. As nitrogen gas enters the computers 101 and 102 and rises along their heights, all possible smoke in the computer is extinguished.

The operation of this system can also be represented as follows-according to the above.

1. In the first stage, smoke, smoke gas, and heat are drawn out of the room by sprinkling water only at high pressure through nozzles (1, 2, 1a ', 1b', 2a ', 2b'). When water is sprayed, a strong suction effect occurs and smoke is drawn into the pipe net 3 and the pipe systems 3a 'and 3b' must pass through the purified water fog in the pipe net and the pipe system. When only water fog, ie without nitrogen, is sprayed through the pipe net and must pass through at least one elbow pipe, the fog turns back into water, gathers into a tank (not shown) or falls into a sewer (not shown) Therefore, contaminated water is prevented from entering the room 100 containing sensitive electronic equipment. Nets or meshes (not shown) of pipe nets or pipe systems can have the same effect as elbow pipes to prevent the spread of fumes containing extinguishing gas into rooms or subfloor spaces. Purified air (no smoke gas, smoke or water) is thus sprayed from the pipe net or pipe system through the discharge openings 4, 5, 45a ', 45b'.

2. When the gas enters the water fog, or when the accumulators 15 and 15 'are used, the water droplets become more separated and obtain a higher velocity, and thus can pass through the elbow pipe without changing back to water. In this case, the extinguishing liquid mixed with gas may come out of the pipe net 3 and the pipe systems 3a 'and 3b' and extinguish the fire.

3. Fire extinguishing in the subfloor 23 is achieved by mixing the water fog with gas, which creates a gas / water mixture that is heavier than air. The pressure is also increased in the subfloor and when sufficient concentration is achieved, the gas / water mixture rises into the computer via the air inlets 103 and 105. Another reason is that the nitrogen / water mixture is colder than the temperature at the top of the room, so the mixture rises to a warmer room. Tests show that higher computers and equipment evolve faster. The chimney effect is more effective for higher installations.

Thus, the system of FIG. 1 functions in such a way that, in brief, the composition of the mist is changed by spraying a mist containing a relatively large amount of nitrogen gas and very little water, and then the smoke is sucked out and purified by spraying water fog. do. The water content of the fog forces the nitrogen gas down towards the floor. As the water sinks further, the nitrogen gas separates from the fog and rises, which extinguish any possible fire that is still smoking. Electricity is not necessary to operate this facility. This is a great advantage because electricity is not always available when a fire occurs.

The present invention has been described above with respect to only one embodiment. It can be pointed out that the present invention can be changed in various ways within the scope of the enclosed claims for details thereof. Thus, the width and shape of the pipe system and the pipe net may vary, for example, the number of spray heads may vary, and the number of spray and intake openings may vary. The number of spray openings and suction openings of the intermediate pipe section may be, for example, 2 to 20. It is also conceivable that the intermediate pipe section, especially if the intermediate pipe section is long, will have simultaneous intake near one or more spray heads of the type that are capable of generating fire extinguishers in the form of finely divided water mists with large penetration capabilities. . By arranging such spray heads in turn at a suitable distance and spraying them in the same direction, an augmentation of the finely divided water fog by the suction is achieved. It is also conceivable that one spray head or more may be placed in the first extended pipe portion or the second extended portion, with spray heads replenishing or replacing the spray head / spray heads in the middle. . The first elongated pipe section is not necessarily directed in equilibrium with the second elongated pipe section, although this structure is simple, it takes up very little space in the room and produces good results. When a digester fluid source of a hydraulic accumulator is used, the throttle may alternatively be installed, for example, as openings are made in the pipe wall of the lychee tube at the lower end of the ascending tube. The number of side openings of the rising tube may be much larger than shown in the drawing. It is also conceivable that there can be only one side opening. The suction unit in the upper part of the room or space, ie the pipe system, may be a vertical pipe with only a suction opening at the top and elbow (to prevent water from flowing out of the room) and a spray opening at the bottom. In order to achieve a more even distribution, however, it is more preferable to use a lower pipe at the floor height or a long pipe at the ceiling height. Regarding a small room, one pipe in the room is enough; Larger rooms require two or more pipes with double spray heads at each end of the pipe. It can be pointed out that the present invention can be understood as a driving source without a hydraulic accumulator.
