較的高価な不活性ガスである。It is often necessary to inert the container. Flushing the air with an inert gas - or replacing the space from which the liquid has been extracted or leaked with an inert gas - is carried out. In the first instance it is desirable to complete this cleaning process quickly. In the second case it is advantageous to adapt the inert gas flow to the required quantity as best as possible. In both cases, nitrogen extracted from a pressure vessel is well suited for extreme pressure. However, nitrogen is a relatively expensive inert gas.

困難なのが欠点である。General [(℃) due to combustion of liquid or gaseous fuel with air
The resulting exhaust gas is inexpensive. In this case, depending on the intended use, it is necessary to remove water and, in particular for metal processing, remove carbon dioxide or residual oxygen.Despite the expense, the inert gas obtained from this exhaust gas can be obtained by air separation methods. It is cheaper than nitrogen. The disadvantage of using inert gases obtained by combustion of liquid or gaseous fuels, compared to the use of nitrogen, is that it is more difficult to adapt the inert gas production to the required quantities.
液体またはガス燃料の燃焼忙よって得る不活性ガス製造
装置の核心は燃焼装置である。たとえば排ガス流の大き
さ忙よって決定されるこの燃焼装置の能力は上方にも下
方にも制限される。The core of an inert gas production device obtained by burning liquid or gaseous fuel is the combustion device. The capacity of this combustion device, which is determined, for example, by the magnitude of the exhaust gas flow, is limited both upwardly and downwardly.
調節範囲は比較的小さい。それゆえ液体またはガス燃料

後に本発明の目的はこの方法を有利に実施しさる装置を
得ることである。The adjustment range is relatively small. The problem therefore arises of economically compressing the inert gas produced during the combustion of liquid or gaseous fuels and of extracting as much as possible of the moisture produced during the combustion from this gas. A further object of the present invention is to remove the carbon dioxide content of the inert gas generated during combustion. Finally, it is an object of the invention to obtain a device with which this method can be carried out advantageously.
この目的を解決するため、内燃機関の排ガスの少なくと

としない。圧縮した不活性ガスはそのまま使用すること
ができる。To achieve this object, it is proposed to cool at least a portion of the exhaust gas of the internal combustion engine and compress it in a compressor, the compressor being driven by the internal combustion engine. With this measure, the uncirculated exhaust gas of an internal combustion engine, in particular a gas or diesel engine, is compressed after intercooling in a compressor, the compressor being driven by the internal combustion engine generating an inert gas. With intercooling, the compressor used is not thermally overloaded and does not require special specifications. Compressed inert gas can be used as is.

圧も同じ比で上昇する。In addition, the exhaust gas must be heated to a pressure higher than 10-9 liters, especially 20~
It is proposed to compress to 50/sail and cool to below 60° C. after compression. Compression to high pressure also increases the partial pressure of water at the same rate.
しかし１００℃より低い温度への冷却罠より圧縮後の分
圧より低い水の飽和分圧が決定される。However, a cooling trap to a temperature below 100° C. determines a saturation partial pressure of water that is lower than the partial pressure after compression.

ることができる。Furthermore, it is proposed to store the inert gas after compression in a prepressure pressure vessel for use as inerting medium. This storage allows the inert gas to be adapted to the percussively generated requirements.

剰の２酸化炭素は液体の形に凝縮し、凝縮しない残りの
不活性ガスから分離することができる。According to one variation of the method, the exhaust gas is compressed to a pressure higher than the critical pressure of carbon dioxide ([200 to 5 OOJ-L) and cooled to a temperature lower than the critical temperature of carbon dioxide (1 m31 °C). Then, the liquefied carbon dioxide is separated from the remaining non-condensable inert gas. According to this method, the partial pressure of carbon dioxide increases during compression according to the compression ratio. When cooled to a temperature below the critical temperature of carbon, especially below 31°C, the saturation pressure of carbon dioxide is therefore lower than the partial pressure achieved. Excess carbon dioxide condenses into liquid form. and can be separated from the remaining inert gases that do not condense.

る。To implement this method, it is proposed to provide an exhaust gas line between the internal combustion engine and the compressor, with a heat exchanger arranged in between. Furthermore, it is proposed to arrange a pressure vessel behind the compressor and to arrange a heat storage exchanger in the conduit leading from the compressor to the pressure vessel. These two proposals ensure that the exhaust gases of the internal combustion engine to be compressed are cooled before entering the compressor. Furthermore, it is ensured that the compressed exhaust gas flowing from the compressor to the pressure vessel is cooled in such a way that the temperature which has increased due to the heat of compression is reduced.

されていることは明らかである。It is proposed to further include a heat exchanger Kal condensate. In the case of a heat exchanger located between the internal combustion engine and the compressor, this condensate drain serves to remove condensed water, and in the case of a heat exchanger located between the compressor and the pressure vessel, it serves to remove the condensed dioxide water. It is clear that the condensate drain is designed as a gate in the case of internal pressures higher than atmospheric pressure, which serve to remove the carbon.

よりこれが避けられる。Furthermore, it is proposed to provide a check valve between the compressor and the pressure vessel, which can open in the direction of the pressure vessel. During operation, it is unavoidable that operating conditions occur, for example, where the pressure in the filled pressure vessel is greater than the pressure generated by the starting compressor. In this case, if the pressure of the pressure vessel acts on the compressor, starting of the compressor is significantly prevented by the check valve pressure.

断されない。This method allows the exhaust gas of an internal combustion engine to be compressed. Furthermore, by suitable cooling, most of the water can be condensed out. Suggestions for using an internal combustion engine to drive a compressor When using fuels with high calorific values such as oil, benzene, teasel oil, and natural gas, all the exhaust gas from the internal combustion engine is captured and this exhaust gas is removed. Na l
It has been found that sufficient power can be obtained to compress pressures higher than the Qzeel, often 20 to 25 sails. An unexpected side effect is that the high inherent reliability of the system is obtained at low monitoring costs, since compression is predicated on a corresponding exhaust gas generation; can do. Since the compressor is driven by an internal combustion engine that produces inert gas as exhaust gas, the compressor is not electrically connected or disconnected.

It was clear that Le was busy enough to compress higher. Compress the exhaust gas to a higher pressure than the critical pressure of carbon dioxide,
When the exhaust gas is finally cooled below the critical temperature of 31° C., the carbon dioxide content of the exhaust gas is condensed. The liquid carbon dioxide can easily flow to the second pressure vessel, leaving behind a non-condensing inert gas force consisting mostly of nitrogen.

already requires an inert gas capacity greater than 200 m”/h, but since the interval between two inertizations does not need to be earlier than 3 h depending on the process, an inert gas capacity greater than Sod in the expanded state Any storage container with this capacity can be used.

The cooling water requirement is approximately 1 d/h, including cooling of the engine and the compressor itself. The engine and compressor operate continuously until the pressure vessel reaches its final pressure of 30/m3. A single cleaning of the container (som') can then be carried out in a few minutes by rapid discharge from the pressure container.

The internal combustion engine 2 receives fuel from a fuel tank l, for example via a carburetor or an injection tank. Fuel air is drawn in through the intake pipe 3 and fed to the combustion chamber; the exhaust gases of the engine leave the engine via the conduit 4.1 and flow through the first heat exchanger 5; In many cases, the condensate that is generated is transferred from the heat exchanger to the condensate drain 12.
[Derived from. The mechanical work of the internal combustion engine 2 is transferred via the shaft 6 to the compressor 7, with optionally an intermediately connected clutch. The suction port of the compressor 7 is the conduit 4
．． 2 to the outlet of the heat exchanger 5. The outlet of the compressor itself also leads to 51 heat exchangers 9 via conduits 8'. The cooled and compressed gas is supplied via conduit 1G to pressure vessel 11 or immediately to the point of use. The condensate generated from the condensate drain 12 is removed. The check valve 13 prevents compressed inert gas from flowing backwards from the storage container 11 to the compressor.
The compressor can thus be started without back pressure. Inert gas is removed for use via valve 14.
