埃を含有する高温の生ガス用の濾過装置に関する。[Detailed description of the invention] The present invention has a plurality of filtration chambers having filter bodies, and these filtration chambers are connected to one common raw gas pipe and a pressureless dust collection container on the raw gas side. On the clean gas side, it opens into a common clean gas collecting line and can receive pressure from individual blow-back lines to purify the filter body.Filtration for hot raw gas containing dust. Regarding equipment.

のことは例えば石炭あるいは石油のガス化の際重要であ
る。With this advanced fa filtration device, the hot dust-containing raw gas produced in high-temperature processing is cleaned without prior cooling. On the one hand, this means that the raw gas can further be used as a hot process gas, which is important, for example, in the gasification of coal or oil.
他方では1.高温で濾過することにより、生ガスの露点
を下回らないので、管路および弁類に煤が付着しない。On the other hand, 1. By filtering at a high temperature, the dew point of the raw gas is not lowered, so soot does not adhere to pipes and valves.

から圧力を受ける。In filtration devices of the type mentioned at the outset, the cleaning of the filter bodies of the individual filtration chambers is carried out at successive intervals with blow-back gas, the filtration operation of the filtration device as a whole being not interrupted, but only the filtration Only the filter body of the chamber receives pressure from the blowback line.
冒頭に挙げた種類の公知の濾過装置は、圧力を受けてい

スは常にすべての濾過室、したがって濾過体を浄化しな
ければならなr4過室にも生ずるので、生ガスが正圧を
受けている場合には吹き戻しガスが作用し得ないことが
あるからである。Known filtration devices of the type mentioned at the outset can only be used in the case of unpressurized raw gas. Since the raw gas always occurs in all filter chambers and therefore also in the filter chambers where the filter bodies must be purified, no blowback gas can act if the raw gas is under positive pressure. This is because there is.
本発明の課題は、圧力を受けている高温の生ガスが予め
圧力を低下させることなしに濾過されかつ濾過体が効果
的に浄化されるような冒頭に挙げた神類の濾過装置を提
案することである。The object of the present invention is to propose the above-mentioned divine filtration device in which high-temperature raw gas under pressure can be filtered without reducing the pressure in advance and the filter body can be effectively purified. That's true.
本発明によればこの課題は、生ガス管路内に大気圧より
高い圧力(正圧)が生じ、各濾過室と集塵容器との間に
塵埃しゃ新機構が設けられ、各濾過室と生ガス管路との

閉じられ、この濾過室に付属する塵埃しゃ新機構が開か
れ、この場合清浄ガス′集合管路がこの濾過室用の吹き
戻し管路であることによって解決される。According to the present invention, this problem can be solved by creating a pressure higher than atmospheric pressure (positive pressure) in the raw gas pipeline, and by providing a new dust blocking mechanism between each filtration chamber and the dust collection container. A raw gas shutoff mechanism is provided between the raw gas pipe line, and the raw gas shutoff mechanism attached to this filtration chamber is closed to purify the filter body in the filtration chamber, and the dust shutoff mechanism attached to this filtration chamber is closed. A new mechanism is opened, which is solved in that the clean gas collecting line is a blow-back line for this filter chamber.
したがって、正圧を受けている高温の生ガスを直接すな
わち予めの圧力低下および温度低下なしにha過するこ
とかできる。この場合生ガス温度は1000’Cまで達
することがある。生ガスの圧力は2ないし3 barで
あり、例えば2.5barである。濾過装置により高い
分離度が得られる。It is therefore possible to pass the hot raw gas under positive pressure directly, ie without a previous pressure drop and temperature drop. In this case the raw gas temperature can reach up to 1000'C. The pressure of the raw gas is 2 to 3 bar, for example 2.5 bar. A high degree of separation can be obtained with the filtration device.
正圧で高温ガスを濾過することにより、単位時間におい

行なった結果、本発明による濾過装置、が無圧の濾過の
場合の比較の対象になり得る濾過装置より5ないし6倍
小さくなり得ることがわかった。By filtering the hot gas under positive pressure, a greater amount of raw gas is passed through the filter chamber in a unit time than in the case of pressureless filtration for standard conditions. Therefore, the filtration device can be constructed smaller than in the case of pressureless filtration. Comparative calculations have shown that the filtration device according to the invention can be 5 to 6 times smaller than a comparable filtration device for pressureless filtration.

べき生ガスとほぼ同じ温度を示すので、濾過体に温度変
化が生ぜずかつ濾過体および管路に凝縮が行なわれずし
たがってまた煤も付着しないという利点を持つ。Furthermore, the present invention allows effective regeneration of the filter body,
This regeneration is important at high degrees of separation and therefore when large amounts of dust are generated on the filter body. Purification of the filter body in the filter chamber takes place by blowing back gas not against the positive pressure of the raw gas, but against a pressureless dust collection container. Therefore, in principle, the clean gas itself, which is under the positive pressure of raw gas, can be used as blowback gas. Moreover, this means that the amount of gas that serves to regenerate the filter element has approximately the same temperature as the raw gas that is to be cleaned, so that no temperature changes occur in the filter body and that no condensation occurs in the filter body and lines. It also has the advantage of not attracting soot.
吹き戻しガスを付加的に加熱する必要がない。There is no need to additionally heat the blowback gas.
濾過室の濾過体を浄化するために、濾過装置の濾過運転
は全体として中断されない。個々の濾過室の浄化は順次
に間隔を置いて行なわれる。To clean the filter body of the filter chamber, the filtration operation of the filtration device is not interrupted as a whole. Purification of the individual filter chambers takes place at successive intervals.

の周囲空気はその後再び加熱される。If the blowback is not carried out by the clean gas itself, the present invention provides an alternative configuration in which a pressure higher than atmospheric pressure (positive pressure) is created in the raw gas line and a cell is created between each filter chamber and the dust collection container. A new dust barrier mechanism is installed, a new raw gas barrier mechanism is installed between each filtration chamber and the raw gas pipeline, and a new clean gas barrier mechanism is installed between each filtration chamber and the clean gas collecting pipeline. A pressure vessel is provided which is connected to the raw gas line for heat exchange, and which is connectable to each filtration chamber via a blowback mechanism and to the ambient air via a valve. This is possible, and is characterized in that when the raw gas shutoff mechanism and clean gas shutoff mechanism are closed and the dust shutoff mechanism and blowback shutoff mechanism of the filtration chamber are opened, the filtration chamber receives pressure from the pressure vessel. In this embodiment of the invention, a certain volume of ambient air from the raw gas line is heated in the pressure vessel, so that the pressure in this pressure vessel is increased;
Suitable for purifying filter bodies. When opening the new blow-back mechanism and the new dust removal mechanism and when closing the fresh gas exchange mechanism and the clean gas exchange mechanism, the pressure is removed from the pressure vessel through the filtration chamber and the filter body in this filtration chamber is purified. do. Additional ambient air can be introduced by opening the valve, which is then heated again.

うことができる。In a further embodiment of the invention, the clean gas collecting line is connected to the pressure vessel. In this case, this connection can be made for the connection of the pressure vessel and the surrounding vessel or instead of this connection.
清浄ガス集合管路を圧力容器と接続することは有利であ

き戻し流がない場合には行なわれない。It is advantageous to connect the clean gas collecting line to the pressure vessel. This is because it allows the blowback flow to be adapted. This adaptation does not take place if there is no blowback flow from the pipe piece of the filter chamber which is connected to the clean gas collecting line and leads off the clean gas.

The filtration chamber 4 then operates again in filtration mode. Subsequent filter chambers 4 can then be cleaned, the cleaning of these filter chambers 4 being carried out one after the other at fixed but adjustable time intervals or depending on the differential pressure occurring across the filter body 7. This pressure difference increases as the amount of dust increases. Filtration chamber 4
Since the filtration operation of the other filtration chambers 4 is continued during the purification of the filter body 7, the purification as a whole does not mean interruption of the filtration operation.

。圧力容器21内において吹き戻し流のだめの清浄ガス
の付加的再熱が行なわれる。In the above-mentioned purification process of the filter body 7 of the filtration chamber 4, purification is performed by the clean gas itself from which dust is removed. The clean gas has almost the same pressure as the raw gas, and the raw gas side space of the filtration chamber 4 is provided without pressure for purifying the filter body 7, so that the dM slag can be effectively peeled off. It is done. Since the humidity of the clean gas is approximately as high as the temperature of the raw gas, condensation and soot build-up in the lines and filter bodies are avoided. Additional reheating of the clean gas in the blowback stream takes place in the pressure vessel 21.
これは必要ではないが、しかし有利である。This is not necessary, but advantageous.
吹き戻ししゃ新機構20の開口断面積は清浄ガスしゃ新
機構13の開口断面積より小さい。したがって吹き戻し
流の流速が清浄ガス流の流速より大きくなるので、濾滓
の吹き戻しが容易になる。The opening cross-sectional area of the blowback barrier mechanism 20 is smaller than the opening cross-sectional area of the clean gas barrier mechanism 13. Therefore, the flow rate of the blowback flow is higher than the flow rate of the clean gas flow, so that the filter slag can be easily blown back.

得られる。If blowing back is performed exclusively or selectively with outside air instead of clean gas for reasons of operation or safety regulations, a pressure vessel 21 is installed and a new mechanism 20 for blowing back is used.
It is necessary to connect this pressure vessel to each filtration chamber 4 via. Valve 22 is now closed. Purification of one of the filter chambers 4 takes place in that the air entering the pressure vessel 21 through the vacuum valve 24 at 0.degree. C. is heated in the pressure vessel 21 and the pressure of the air is increased. When one of the blowback mechanisms 20 is opened with the dust barrier mechanism 15 open and the raw gas barrier mechanism 12 and the clean gas barrier mechanism 13 closed, the pressure generated in the pressure vessel 21 As the tIIi slag is peeled off, the pressure inside the pressure vessel 21 decreases, and fresh air is sucked in from the surroundings via the vacuum valve 24. Since the sucked outside air is heated again, new pressure is obtained for the next purification of the filter body 7 in the filter chamber 4.
