Abstract

The high pressure fluid canon includes a propellant gas chamber (24) and valve member (11) for opening a connection between this and the fluid chamber. A pressure compensator (35) coupled to the valve member is used to reduce the switch pressure in the switch chamber (26) by compensating at least partly the force which can be exerted on the valve through the pressure prevailing in the propellant gas chamber. to produce the required switching pressure, part of the propellant gas in the chamber can be diverted into the switch chamber.

Description

The invention relates to a high-pressure fluid gun, in particular other for extinguishing fires, according to the generic term of the other saying 1.

Most fire extinguishers use the extinguishing agent blown out of a storage container by a propellant gas, the extinguishing agent consumption is very high and large part of the extinguishing agent cannot work, but is lost unused.  

In DE 195 09 322 A1 we therefore use a high-pressure fire Extinguishing cannon proposed an extinguishing agent chamber, a Extinguishing agent supply line for filling the extinguishing agent chamber, one Compressed gas chamber and a compressed gas supply line, through which the Compressed gas chamber can be filled. One between the compressed gas and the valve arranged in the extinguishing agent chamber is in filled state due to the pressure in it held closed position. To be operated by means of a A part of the gas is thus diverted to the triggering device that a force acting on the valve is generated, which opens the valve. The extinguishing agent becomes impactable blown out and strikes in an extremely fine distribution on the source of the fire.

A disadvantage of the proposed in DE 195 09 322 A1 The solution is that a high proportion of gas comes from the compressed gas mer to trigger the valve is needed to the cannon trigger. On the one hand, this is with a high loss connected, on the other hand there is no longer the full one Filling pressure available for shooting, so that their performance subsides.

The present invention has for its object a High pressure fluid gun to create a lower one Loss energy and easy and inexpensive to manufacture is cash.

This object is achieved by a High-pressure fluid gun with the features of claim 1 solved.

The high-pressure fluid cannon according to the invention only a small proportion of that in the LPG chamber Pressure is needed to trigger the cannon.  

According to the invention, we are effectively under pressure lower the projection of the surface onto the plane right to the direction of action, for example in the direction of displacement, Roger that. In the preferred embodiments, the effectively pressurized the projection of the Area on the plane perpendicular to the direction of movement of Control piston, pressure compensator or valve means.

Fig. 1 shows a substantially cylindrical high pressure fluid cannon, which is provided for fire fighting and is operated with an extinguishing agent as a fluid. It is therefore referred to below as a high-pressure extinguishing agent cannon 1 . The high-pressure extinguishing agent cannon 1 has a front extinguishing agent part with a permanently integrated fluid or extinguishing agent chamber 16 and a rear pressure gas part, in which, depending on the application, a compressed gas cartridge 2 or a plasma cartridge 3 with a compressed gas chamber 24 can be used to generate the driving energy. Of course, it is also possible to firmly integrate the compressed gas chamber 24 into the high-pressure extinguishing agent cannon 1 .

The extinguishing agent chamber 24 is provided with an extinguishing agent connection 13 and an extinguishing agent supply line 14 , via which the extinguishing agent chamber 24 can be filled with extinguishing agent. Water is preferably used as the extinguishing agent, but the high-pressure extinguishing agent cannon 1 can in principle be operated with any fluid, that is to say not only with liquids, but also with gases, emulsions, dispersions, etc., which can be expelled using a propellant gas. This also applies in the same way to all other embodiments described in this application. In the Löschmittelzulei device 14 , an extinguishing agent check valve 17 is provided which closes the extinguishing agent supply line 14 during a shot.

On the high-pressure extinguishing agent cannon 1 are a handle 96 with a trigger switch 12 b, with which a trigger valve 12 can be actuated, and a second handle 60 is provided for easier handling.

The front end of the high-pressure extinguishing agent cannon 1 is provided with a cannon outlet nozzle 20 , which serves to achieve a suitable extinguishing jet profile and widens towards the front. The cannon outlet nozzle 20 is connected to the cannon body via a thread 21 , so that depending on the application, a cannon outlet nozzle 20 with a larger or smaller opening angle can be used. At a small opening angle, preferably 3 °, there is a more extensive, highly focused beam with increased speed, with the help of which the safety distance from the source of the fire can be increased. With a larger opening angle, before 7 °, there is a wider spreading of the beam. A cannon outlet valve 19 prevents leakage of the extinguishing agent in the closed state and is so aerodynamically shaped in the open state that the extinguishing agent jet is hardly influenced. An extinguishing agent chamber vent 18 is further provided between the extinguishing agent chamber 16 and the cannon outlet nozzle 20 .

Fig. 2 shows an embodiment of a compressed gas cartridge 2 with a substantially cylindrical housing 34. A central valve arrangement is integrated in the housing 34 , the parts of which are partly fixedly connected to the housing 34 and partly displaceably mounted relative to the housing 34 . The propellant gas chamber arranged in the housing in the form of a compressed gas chamber 25 narrows in the direction of the extinguishing agent chamber 16 (towards the front) and opens into a cylinder nozzle 25 of smaller diameter, which is also cylindrical in shape, and which is provided at the front end with a wall reinforcement 33 . After insertion of the compressed gas cartridge 2 into the high-pressure extinguishing agent cannon 1 via the cartridge barrel 8 and the cartridge nozzle barrel 10 , the extinguishing agent chamber 16 and the compressed gas chamber 24 of the compressed gas cartridge are separated from one another by the main valve closure 11 and can be connected to one another.

To reduce the setback occurring when the high-pressure fluid cannon 1 is triggered, the compressed-gas cartridge 2 is spring-loaded in the high-pressure extinguishing agent cannon 1 .

When shooting, the compressed gas cartridge 2 moves in the Pa tronenlauf 8 and cartridge nozzle barrel 10 to the rear. The wall reinforcement 33 serves to create a sufficient channel between the main valve closure 11 and the cartridge nozzle barrel 10 , even when the compressed gas cartridge is moved to the rear.

The main valve has a cylindrical Hauptventilgehäu se 29 , the outer diameter of which widens towards the front. Furthermore, a main valve control piston 36 which is guided in a gas-tight manner in the main valve housing 29 and which separates the switching chamber 26 located in the housing from the compressed gas chamber 24 . On its side facing the compressed gas chamber 24 , the main valve control piston 36 is provided with a pressure disc 35 , the diameter of which is significantly larger than that of the main valve control piston. The druckgaskam merabgewandte outer surface of the printing plate 35 abuts the pressure to wheel diameter expanded Hauptven tilgehäuse 29 in form-fitting manner, in addition Tung breather holes are provided in the main valve housing 29 30th

The pressure plate is connected via a main valve rod 98 , which is guided in a barrel 32 in the compressed gas cartridge 2 , to the main valve closure 11 and is supported by a return spring 31 on the compressed gas cartridge 2 . The main valve is opened by a forward movement of the Hauptven valve rod, the main valve closure 11 releasing the connection between the compressed gas chamber 24 and the extinguishing agent chamber 16 .

The main valve also has a switching chamber venting device 27 , which is closed by the main valve control piston 26 when the main valve is closed and is released by the main valve control piston 36 when the main valve is open.

The diameter of the main valve closure 11 is selected to be slightly smaller than that of the pressure disk 35 . In this way, the force exerted on the pressure plate 35 to the rear is slightly greater than the force exerted on the main valve closure 11 in the forward direction and the valve is brought into the closed position when the switching chamber is vented. The area of the main valve control piston 36 facing the switching chamber 26 is larger than the difference between the areas of the pressure plate 35 and the main valve closure 11 . As a result, the main valve control piston 36 can be controlled with a relatively smaller control pressure than the pressure in the propellant gas chamber 24 .

The main valve is controlled via a combination of a control valve 6 and a pulse frequency control valve 7 , which are arranged in the rear part of the compressed gas cartridge 2 and which are shown as a section in FIG. 4.

The control valve 6 consists of a control valve housing 44 , in which a control valve closure disk 47 is arranged, which can be pressed by a control valve spring 46 against an opening 43 , which connects the valve to the pressure gas chamber 24 , and thus closes the opening to the pressure gas chamber 24 . The control valve spring 46 is supported on a spring adjusting screw 45, can be set on the turn with the help of a knob 48, the hardness and thus the pressure of the control valve spring 46th

The gas can flow from the control valve 6 into the switching chamber 26 via the pulse frequency control valve 7 . The Pulsfre frequency control valve 7 consists of a cylindrical housing in which a cylindrical body 40 is rotatably mounted. The cylindrical body 40 has three radial bores 39 a, b, c and an axial bore extending from the radial bores 39 a, b, c to the front edge. The radial bores 39 a, b, c are in contact with the radial Boh tion and are arranged so that they can be connected by rotating the cylindrical body 40 with a connecting line 28 between the control valve 6 and pulse rate control valve 7 , so that the gas through Pulsfre frequency control valve can flow through. The bores 39 a, b, c have different radii, so that the flow through the pulse frequency control valve 7 can be varied in three stages. However, if the cylindrical body 40 is rotated with the position marked P in the direction of the connecting line 28 , the connection between the switching chamber and the control valve is completely interrupted. A manually operated setting button 49 is used to set the pulse frequency control valve 7 and is secured in the respective position by means of a position catch spring 41 . Alternatively, a continuously adjustable valve can be used.

Fig. 3 shows an embodiment of a fuel plasma cartridge 3 , which can be used as an alternative to the compressed gas cartridge 2 to achieve particularly high driving energies. The fuel plasma cartridge 3 is constructed in principle the same as the compressed gas cartridge 2 . The main difference is that the propellant pressure in the propellant chamber 24 is not by compressed gas, but by the ignition of an explosive mixture with the aid of a spark plug 57 . No pulse frequency control valve 7 (see FIG. 2) is also provided here, but the pulse frequency is set via the ignition. In addition, control valve 6 and switching chamber 26 are coupled via a large connecting line, so that the explosive pressure increase leads to a rapid opening of the main valve closure.

The fuel-air mixture is supplied with the aid of a fuel connection 53 , the amount of fuel being able to be set via a fuel supply adjusting valve 54 . At the entrance to the compressed gas chamber 24 , a double check valve 55 is provided, with the aid of which the supply of combustion air and fuel is released or blocked. In addition, the fuel plasma cartridge ne 3 behind the double shut-off valve 55 has a fuel mixing chamber 56 which serves to mix the fuel with the combustion air.

The filling pressure of the fuel-air mixture is wide Limits can be varied and are usually around 5 bar. The propellant gas energy is about the filling pressure and the burning proportion of substance in the mixture to the respective conditions of adjustable to extinguish fire.

Fig. 5 shows a preferred embodiment of a cannon outlet valve 19 ; top left a front view with cannon outlet nozzle 20 , with minimum and maximum Düsenum fang 20 a, 20 e, in the closed position; to the right is a side view in the open position; underneath a front view in. This is a particularly streamlined flap valve which only slightly influences the flow properties of the escaping gas-extinguishing agent mixture. It consists of a right-hand and a left-hand valve flap 19 a, 19 e, which are attached to the outlet opening of the high-pressure extinguishing agent cannon via a flap holder 19 z that can be pivoted perpendicular to the direction of flow. The right and left flaps are held in the closed position by springs 50 and premature leakage of the extinguishing agent is prevented. When the cannon is triggered, the springs are pressed into the streamlined open position by the gas pressure. After unloading, the flaps snap back into their starting position.

Fig. 6 shows a high-pressure extinguishing agent cannon 1 with extinguishing medium chamber 16 and a firmly integrated compressed gas chamber 24 , which is also suitable for the use of pressurized extinguishing agent. It differs in union union from the embodiment shown in FIG. 1 in that the movements of the main valve breech 11 and the cannon outlet valve 19 are coupled to one another by a second valve rod 99 . If the Hauptven valve closure 11 is opened, the cannon outlet valve 19 also opens automatically.

The diameter of the main valve seal 11 is approximately the same as the diameter of the gun exit valve 19, so that the shutter on the main valve 11 and the pressure applied to Kano 19 aufhe nenausgangsventil mutually ben. Since the cannon outlet valve 19 does not open in this way due to the pressure built up in the extinguishing agent chamber 16 , the extinguishing agent can also be filled into the extinguishing agent chamber 16 under increased pressure without fear of premature leakage of the extinguishing agent.

The use of an extinguishing agent chamber vent 18 can be dispensed with in this embodiment. For this, the Kanonenausgangsdüse 20 is shaped so that a nozzle pre-chamber 20 is formed b, which serves to improve the emerging from the high-pressure extinguishing agent gun 1 extinguishing agent flow.

Fig. 7 shows a detailed view of a pressure gas chamber 24 integrated into the high-pressure extinguishing agent cannon in a first embodiment. The compressed gas chamber 24 is also essentially cylindrical in shape and narrows in the direction of the extinguishing agent chamber 16 (to the front). The main valve closure 11 separates the compressed gas chamber 24 and the extinguishing medium chamber 16 from one another.

Here also a coupled with the main valve closure 11 and a pressure plate 35 provided control piston 36 see easily.

In the rearward extension of the main valve rod 98 , a compressed gas chamber inlet valve 59 is provided, with the aid of which the compressed gas supply line 5 can be closed. The guided in the pressure gas chamber input valve 59 Eingangsventil- closure piston 59 a is connected via a third valve rod 97 with the main valve spool 36th The here achieved by coupling the movements of input valve-lock piston 59 a and main valve control piston 36 leads in the selected arrangement to the fact that the supply of further compressed gas is prevented during a shot of the high-pressure extinguishing agent cannon 1 .

The diameter of the main valve stopper 11 may be chosen the same in this case as that of the pressure disk 35, as holding in the closed position by the forward direction of the pressure gas chamber 24 face of the inlet valve closure piston 59 a is an additional rearwardly directed force tilverschluß the Hauptven. 11 The neces sary, compared to the pressure in the pressure gas chamber 24 significantly reduced switching pressure arises here from the area of the inlet valve sealing piston 59 a.

In this embodiment, instead of a control valve 6 and one of them separate manual release valve 12 for filling the compressed gas chamber 24 and extinguishing agent chamber 16 directly connected to the switching chamber 26, actuated by a magnetic coil 90 switching valve b provided 12th

The switching valve 12 b consists of a switching valve housing 92 , in which a control valve locking piston 94 is arranged, through which the connection between the switching chamber 26 and the compressed gas chamber 24 can be closed. The switching valve spring 93 is used to hold the control valve closure piston in the closed position, or to reset the release switch 12 a coupled to the solenoid 90 to the initial position after releasing it. The Auslöseschal ter 12 a is, as can be seen in Fig. 6, arranged on the handle 96 of the high pressure extinguishing agent cannon.

The pulse frequency control valve 7 also serves in this embodiment to adjust the flow of the gas flowing from the compressed gas chamber 24 into the switching chamber 26 . In this case, a continuously adjustable valve is provided.

Fig. 9 shows a detailed view of a pressure gas chamber 24 permanently integrated in the high-pressure extinguishing agent cannon 1 in a second embodiment. In contrast to the exporting of FIG approximate shape. 7 no pulse control valve 7 is here provided more, but the switching valve 12 b also handles the pulse frequency control.

Of FIG. 10 is the switching valve 12 is also b of a switching valve housing 92 in which a control valve circuit Ver piston 94 is arranged, through which the connection between the switch chamber 26 and the compressed gas chamber 24 is closed. About the switching valve spring 93 , the control valve closure piston 94 is held in the closed position, or after releasing the trigger switch 12 a coupled to the solenoid 90 is returned to the starting position.

Instead of a switching chamber ventilation, which is released by the main valve piston in the switching chamber as soon as the main valve triggers (see FIG. 6), the switching chamber 27 is vented in this embodiment via the control valve 12 b. When the Schaltventilver closing piston 94 , the switching chamber vent 27 is open. As soon as the actuation of the trigger switch of the Schaltven tilverschlußkolben 94 opens the connection between Druckgaskam mer 24 and switching chamber 26 , it simultaneously locks the vent line. After the sudden discharge of the high-pressure extinguishing agent cannon 1 , the venting of the switching chamber 26 is initially carried out via the open control valve 12 b in the compressed gas chamber. After closing the control valve 12 b, the switching chamber vent 27 is opened and the switching chamber 26 is brought back to atmospheric pressure.

The switching valve 12 b is triggered by control electronics at the frequency with which the extinguishing agent cannon 1 is to pulse. By varying the frequency of the switching valve 12 b, the filling level of the extinguishing agent chamber 16 can be varied if the filling time of the extinguishing agent chamber 16 is kept constant. In this way it is possible, for example, to operate the extinguishing agent cannon 1 with a half-filled extinguishing agent chamber 16 .

In the following, the interaction of the elements of the device according to the invention with the aid of a high-pressure extinguishing medium cannon 1 with a compressed gas cartridge 2 (FIGS . 2, 4) is illustrated.

By actuating the release valve 12 , extinguishing agent 14 is loaded into the extinguishing agent chamber 16 via the extinguishing agent supply line 16 up to a maximum level of 90%. At the same time, the loading of the compressed gas chamber 24 with gas, for. B. air, nitrogen or carbon dioxide, up to a gas pressure of about 20 to 40 bar.

Characterized in that the diameter of the main valve closure 11 is chosen slightly smaller than that of the pressure disc 35 , the main valve closure 11 is held by the return spring 31 in the closed position. The control valve disc 47 is pressed by the control valve spring 46 against the opening 43 until a sufficient pressure has built up in the pressure gas chamber 24 to overcome the spring force of the control valve spring 46 so that the control valve 6 is filled with gas. The gas flows through the connecting line 28 into the pulse rate control valve 7 and, depending on the position of the cylindrical body 40 through the radial bore 39 a, 39 b or 39 c and the axial drilling 42 through the pulse rate control valve 7 into the switching chamber 26th

By the opposite axial arrangement of Hauptven tilverschluß 11 and thrust washer 35 in the compressed gas chamber 24 and the somewhat smaller diameter of the Hauptventilver circuit 11 of the necessary for the initiation of the main valve switching pressure is very low, since the pressure acting in front of stepping forward and backward direction pressure to Most compensate. By appropriate selection of the diameter of the main valve control piston, the switching pressure required in the switching chamber 26 is usually set at a few percent of the propellant gas pressure prevailing in the compressed gas chamber 24 . The loss energy of the high pressure extinguishing agent cannon necessary for the switching can be limited to a minimum in this way. In any case, however, the area of the main valve control piston 36 must lie above the difference between the areas of the pressure plate 35 and the main valve closure 11 .

In the switching chamber 26 , a pressure is now also built up. As soon as this exceeds the threshold value, which is necessary for triggering the main valve, the Hauptven tilkolben 36 and with this via the main valve rod and the main valve closure 11 in the direction of the Löschmittelkam mer 16 moved. Due to the high pressure in the pressure gas chamber, the main valve opens further and the gas flows at a very high speed from the pressure gas chamber 24 into the extinguishing agent chamber 16 and tears the extinguishing agent there and leaves the high-pressure extinguishing medium cannon 1 through the cannon outlet valve 19th

Due to the significantly smaller diameter of the cartridge nozzle 25 in relation to the diameter of the extinguishing chamber 16 , the gas expands not only to the front but also radially outwards into the extinguishing agent chamber, as a result of which the extinguishing agent is distributed particularly finely and regularly in the propellant gas.

During the firing process, the compressed gas chamber supply line 22 is locked and the extinguishing agent supply line 14 is closed by the extinguishing agent check valve 17 .

As a result of the discharge, the pressure in the pressure gas chamber 24 drops below the switching pressure of the control valve 7 , which closes again. In addition, the switching chamber 26 is vented via the switching chamber vent 27 and the Hauptventilver circuit 11 is pushed back into the closed position by the return spring 31 . The high-pressure Löschmit telkanone 1 is now prepared for a new loading with Löschmit tel and gas and a new cycle can begin by refilling the extinguishing agent chamber 16 and the compressed gas chamber 24 .

In this way, a steady sequence of shots is achieved by holding actuation of the trigger valve 12 without having to trigger each individual shot individually. The high-pressure extinguishing agent cannon 1 works until the loading of extinguishing agent and gas is interrupted by releasing the trigger valve 12 .

About the position of the knob 49 of the pulse frequency regulating valve 7 , the inflow speed of the gas into the switching chamber 36 can be accelerated or slowed down, thereby making it possible to vary the frequency of the successive shots. When fighting less severe fires, water can be saved in this way and the damage caused by the water can be reduced.

Due to the high-pressure extinguishing agent cannon according to the invention, the energy is extracted from the fire to be extinguished on the one hand by the fine extinguishing agent distribution, and on the other hand the oxygen is displaced from the source of the fire. When fighting in the vicinity of the source of the fire, further oxygen is withdrawn from the source of the fire, in particular when using a plasma cartridge 3 operated with a fuel-air mixture, in which the oxygen is consumed by combustion and inert gases with high thermal energy are formed.

In addition to fighting fires, the high-pressure fluid cannon is also suitable for cleaning and temperature control of exhaust gases and used air. Fig. 11 shows an embodiment which is intended for this use. It is a high-pressure fluid cannon 1 , which corresponds essentially to that of FIG. 6. This fluid cannon is also preferably operated with water as the fluid. However, it can, for example, be connected to a cleaning and heat exchange unit gregat 202 (see FIG. 12) and the fluid chamber 16 is additionally equipped with a vent valve 124 . This vent valve 124 serves to completely vent the fluid chamber 16 after discharge into the reactor or the air purification unit, since venting via the cannon outlet nozzle is not possible.

Fig. 12 shows a cleaning and heat exchange unit 202 to which a corresponding fluid gun 1 is connected. The cleaning and heat exchange unit 202 is suitable for cleaning and cooling exhaust gases, in particular Rauchga sen, or other gases contaminated with fine particles. It has a working chamber 253 with a jacket 252 , on the upper side of which the fluid cannon 1 can be connected via a cannon connection 257 . The Arbeitsskam mer 253 is provided with a gas inlet 254 which can be closed via a gas inlet valve 259 and by means of which the working chamber can be filled with the exhaust gas to be cleaned; and a gas outlet 255 , which can be closed via a gas outlet valve 260 , and with the aid of which the cleaned and cooled exhaust gas is discharged from the working chamber 253 . Furthermore, a waste water drain 256 with drain valve 263 is provided, through which the excess water injected into the reactor can be removed together with the washed-out impurities.

In Fig. 13, the schematic structure of a device is shown for the treatment of exhaust air. A central component is the cleaning and heat exchange unit 202 described above with the fluid cannon 1 according to the invention.

The exhaust air to be treated, for example used air from residential and business premises but also from warehouses and the like. Ä., is promoted by a gas pump 330 via a Rückschlagven valve 331 in a gas storage 327 until a pre-ben pressure, z. B. 10 bar is reached.

During this time, the fluid cannon 1 is filled with compressed gas, preferably up to about 25 bar, by means of a high pressure pump 348 via a high pressure gas reservoir 347 . The pressure is monitored by a pressure sensor 349 .

At the same time, the fluid cannon 1 is also filled with the fluid, in this case with water; For this purpose, two water reservoirs 333 , 338 connected to the water network 323 (service or drinking water) are provided, one of which is filled with preheated water, the other with cold water. Depending on whether heating or cooling of the exhaust air is provided, the water reservoirs 333 , 338 are correspondingly removed with the help of the valves 336 , 337 to fill the fluid cannon 1 . However, the use of just one water storage tank is often sufficient. A heater 341 or a cooling element 334 is provided for tempering the water containers 333 , 338 .

As soon as the predetermined pressure in the gas reservoir 327 is sufficient, the gas inlet valve 259 is actuated and the working chamber 253 is filled with exhaust air up to a predetermined pressure of preferably about 5 bar. When the predetermined pressure is reached, the charging process is ended by the pressure detector 261 (cf. FIG. 13) by closing the gas inlet valve 259 and the fluid cannon 1 is triggered. As already described above, the water is atomized into the working chamber during discharge (approx. 20 micrometers) at a speed of up to 400 km / h. On the one hand, the particles contained in the exhaust air are captured and precipitated by the finely divided water, on the other hand, due to the sudden mixing and the large surface area of the water, an energy exchange takes place within a very short time between the injected air-water mixture and the exhaust air.

By enriching the compressed air with oxygen, additional the exhaust air is enriched with oxygen. A Scenting can optionally be carried out over the water become. Furthermore, due to the fine water distribution also an additional humidification of the exhaust air, so that the due to the heating, the room air is often too dry is improved.

The cleaned and temperature-controlled air is fed to an air distribution network 350 via the outlet valve 260 after the discharge process of the fluid cannon 1 . This can optionally also be used for disinfection using an ultraviolet emitter 352 . Furthermore, ionized particles can be removed by supplying water vapor ionized by a high-voltage anode grid 346 .

The precipitated water collects at the bottom of the working chamber 253 , is drawn off via the waste water outlet 256, freed from the washed-out particles by a water filter and returned via the water return 343 into the water cycle.

Fig. 14 shows the structure of an apparatus for cleaning and cooling flue gases and other process exhaust gases. Here too, a cleaning and heat exchange unit 202 with a fluid cannon 1 according to the invention is provided as a central component. It is in accordance with the Vorrich processing of Fig. 14 is supplied with the gas to be purified via a gasspei cher 327 the cleaning and heat exchange unit and treated in accordance with the fluid gun. Since flue gases usually only have to be cooled, only one water container 334 is provided for feeding the fluid cannon 1 . Furthermore, the wastewater withdrawn is not returned, but is instead collected in a wastewater reservoir.

It is particularly advantageous if the waste water storage 354 is thermally connected to the drum storage 327 . This can be done either by means of an additional heat exchanger or by appropriate physical proximity. In this way, the energy of the entering gas can be used to remove the water from the waste water storage 354 and thus to obtain easily depositable residues. In addition, vacuum can be applied to the wastewater reservoir 354 to increase the rate of evaporation of the water.

The invention is not limited in its execution the preferred embodiments given above le. Rather, a number of variants are conceivable, which of the high pressure fluid gun according to the invention also at reason make use of other types of execution. In particular, the use of the high pressure fluid gun not on extinguishing fires, but can be with everyone Applications are used in which fluids, in particular re water, with high speeds and fine distribution lung is needed.
