本考案は力゛ス処理に用いる吸着塔の改良に関するもの
である。[Detailed Description of the Invention] The present invention relates to an improvement of an adsorption tower used for force treatment.
従来のガス処理に用いる吸着塔およびガス処理装置は第
１図に示すように構成されている。An adsorption tower and gas treatment apparatus used in conventional gas treatment are constructed as shown in FIG.
まず吸着塔について説明すると、吸着塔１の一方の側面
にガスは通すが吸着材２は通さないスクリーン３を付設
して被処理ガスの流入口４とし、また当該流入口４に対
面する側に同じようなスクリーン３′を付設して処理ガ

て吸着材２の供給管７を付設するとともに、吸着塔１の
下部をコーン状とし最下部に弁８を介して吸着材２の排
出管９を付設したものである。First, to explain the adsorption tower, one side of the adsorption tower 1 is provided with a screen 3 that allows the gas to pass through but does not allow the adsorbent 2 to pass through, serving as an inlet 4 for the gas to be treated, and on the side facing the inlet 4. A similar screen 3' is attached to serve as an outlet 5 for the process gas, and a supply pipe 7 for adsorbent 2 is attached to the upper part of the adsorption tower 1 via a valve 6, and the lower part of the adsorption tower 1 is connected to a cone-shaped A discharge pipe 9 for the adsorbent 2 is attached to the bottom via a valve 8.
またガス処理装置は送風室１０の内部に前記した吸着塔
１を１塔ないし複数基をシリーズに設置し、送風室１０
の一方にダンパー弁１１を介した被処理ガスの流入管１
２を連通ずるとともに他方に処理ガスの流出管１３を連
通したものである。In addition, the gas treatment device has one or more adsorption towers 1 described above installed in series inside the ventilation chamber 10.
An inflow pipe 1 for the gas to be treated via a damper valve 11 is provided on one side of the
2 are connected to each other, and an outflow pipe 13 for processing gas is connected to the other side.
本装置を用いてガス処理を行なう場合は、まず供給管７
から活性炭、無機吸着材、イオン交換樹脂などの吸着材
２を吸着塔１に充填し、被処理ガスの流入管１２から送
風室１０に被処理ガスを流入せしめ、被処理ガスをスク
リーン３を通過させて吸着塔１内の吸着材２に接触させ
て被吸着物質を吸着せしめ、処理ガスをスクリーン３′
を通過させて処理ガスの流出管１３から流出させる。When performing gas treatment using this device, first
The adsorption tower 1 is filled with an adsorbent 2 such as activated carbon, an inorganic adsorbent, or an ion exchange resin, and the gas to be treated flows into the blowing chamber 10 from the inflow pipe 12 for the gas to be treated, and the gas to be treated passes through the screen 3. The gas is brought into contact with the adsorbent 2 in the adsorption tower 1 to adsorb the adsorbed substance, and the treated gas is passed through the screen 3'.
The processing gas is allowed to pass through and flowed out from the processing gas outflow pipe 13.
このような処理を続行すると、吸着塔１内の吸着材２が
被吸着物質によって飽和されるが、その場合はダンパー
弁１１を閉じて送風室１０への被処理ガスの流入を中断
し、弁６および８を開口して吸着塔１内の飽和吸着材２
を排出管９より取り出す。If such processing continues, the adsorbent 2 in the adsorption tower 1 will be saturated with the adsorbed substance, but in that case, the damper valve 11 is closed to interrupt the flow of the gas to be treated into the ventilation chamber 10, and the valve is closed. 6 and 8 are opened to remove the saturated adsorbent 2 in the adsorption tower 1.
is taken out from the discharge pipe 9.
なお取り出した当該吸着材２は賦活再生あるいは廃棄さ
れる。Note that the taken out adsorbent 2 is activated and regenerated or discarded.
このような吸着材の排出を終了したのち再び吸着塔１に
再生済みのあるいは新品の吸着材２を供給管７から充填
しガス処理を続行する。After such discharge of the adsorbent is completed, the adsorption tower 1 is again filled with regenerated or new adsorbent 2 through the supply pipe 7, and gas treatment is continued.
従来は以上説明したような操作によりガス処理を行なっ
ているが、しかし従来の吸着塔にあっては以下に説明す
るような欠点か゛ある。Conventionally, gas treatment has been carried out by the operations described above, but conventional adsorption towers have drawbacks as described below.
すなわち被吸着物質によって飽和した吸着材２を吸着塔
１から排出する方法に排出管９から真空吸引して吸着材
２を強制的に排出する汽力輸送と、単に弁６と弁８を開
口して自然落下によって吸着材２を排出管９から排出す
る自然落下輸送があるが、汽力輸送においては輸送の際
に約１０％前後の吸着材の摩耗ロスがあり、さらにその
摩耗によって生じる吸着材の粉塵の除去に手間がかがる
ので、一般に自然落下輸送によって吸着材２を排出して
いる。In other words, there are two methods for discharging the adsorbent 2 saturated with the adsorbed substance from the adsorption tower 1: steam transport in which the adsorbent 2 is forcibly discharged by vacuum suction from the discharge pipe 9, and steam transport in which the adsorbent 2 is forcibly discharged by simply opening the valves 6 and 8. There is a natural fall transport in which the adsorbent 2 is discharged from the discharge pipe 9 by natural fall, but in steam transportation, there is a wear loss of around 10% of the adsorbent during transportation, and furthermore, the adsorbent dust is generated due to the wear. Since it takes time and effort to remove the adsorbent 2, the adsorbent 2 is generally discharged by gravity transport.
しかし自然落下輸送によって吸着材２を排出する場合は
、排出時に吸着塔１の下方部において吸着材２がブリッ
ジングを起こしやすく、さらに吸着材２が残留するので
そのためこのコーンの形状を安息角以上の傾斜をもつ形
状、換言すれば細長い形状とせねばならない。However, when the adsorbent 2 is discharged by gravity transport, the adsorbent 2 tends to cause bridging in the lower part of the adsorption tower 1 during discharge, and the adsorbent 2 remains, so the shape of the cone is adjusted to be higher than the angle of repose. In other words, it must have an elongated shape.
ところが第１図で示したようにこのコーン部は被吸着物
質の吸着に関与しない部分なので、コーン部を細長くす
ればする程吸着材の利用効率が低下する。However, as shown in FIG. 1, this cone part is not involved in adsorption of the adsorbed substance, so the more elongated the cone part is, the lower the utilization efficiency of the adsorbent becomes.
またたとえコーン部を細長い形状にしたとしても吸着材
２の排出については万全とは言い難く、時によっては排
出時に吸着材２がブリッジングを起こし、そのために余
分な操作が必要となることもある。Furthermore, even if the cone part is made into an elongated shape, it is difficult to say that the discharge of the adsorbent 2 is perfect, and in some cases, the adsorbent 2 may cause bridging during discharge, which may require extra operations. .
さらに自然落下による場合は排出時間が比較的長くかか
るという欠点もある。Furthermore, there is also the disadvantage that it takes a relatively long time to eject by gravity.
本考案は従来の吸着塔におけるかかる欠点を解決するも

着材の利用効率を高めることを目的とするものである。The present invention solves the drawbacks of conventional adsorption towers by opening one side of the adsorption tower and opening the other side facing that one side, allowing gas to pass through both openings, but causing no adsorption. A screen is attached that does not allow materials to pass through, and one opening is used as an inlet for the gas to be treated and the other opening is used as an outlet for the treated gas.In addition, an adsorbent supply pipe is installed at the top of the adsorption tower. The lower part of the tower is formed into a cone shape, and an adsorbent discharge pipe is provided at the bottom, and a gas blow-off pipe is provided inside the adsorption tower near the junction between the straight part of the adsorption tower and the lower cone part. This invention relates to a gas adsorption tower that is characterized by the fact that the adsorbent packed in the adsorption tower can be taken out in a relatively short time without causing bridging, and the volume of the cone can be reduced and the adsorption material can be removed. The purpose is to increase usage efficiency.

を付設する。As shown in FIG. 2, a screen 3 is attached to one side of the adsorption tower 1 to allow gas to pass through but not to allow the adsorbent 2 to pass through, forming an inlet 4 for the gas to be treated, and the side facing the inlet 4. A similar screen 3' is attached to the top of the adsorption column 1 to serve as an outlet 5 for the process gas, and a supply pipe 7 for the adsorbent 2 is attached to the upper part of the adsorption column 1 via a valve 6. A discharge pipe 9 for the adsorbent 2 is installed at the bottom via a valve 8.
Attached.
そして吸着塔の内部であって吸着塔１の直線部とコーン
部との接合部付近に気体の吹き出し管１４を付設する。A gas blowing pipe 14 is attached inside the adsorption tower near the joint between the straight part and the cone part of the adsorption tower 1.
当該気体の吹き出し管１４は第３図に示したように小孔
あるいはスリットからなる吹き出し口１５を多数設け、
吸着塔１内に均等に気体を吹き出すことができるように
する。The gas blowing pipe 14 is provided with a large number of blowing ports 15 consisting of small holes or slits as shown in FIG.
To enable gas to be evenly blown out into an adsorption tower 1.
また気体の吹き出し管１４の取り付は個数は第２図に示
したように通常は吸着塔１内の両端に取り付けるが、吸
着塔の断面積が大きい場合は吸着塔の四方に取り付けて
もよい。In addition, the number of gas blowout pipes 14 is usually attached to both ends of the adsorption tower 1 as shown in Fig. 2, but if the cross-sectional area of the adsorption tower is large, they may be installed on all sides of the adsorption tower. .
なお気体の吹き出し管１４の任意の個所に気体を送給す
る連通管１６を付設する。Note that a communication pipe 16 for supplying gas is attached to an arbitrary part of the gas blowing pipe 14.
次に本考案の吸着塔の操作を説明する。Next, the operation of the adsorption tower of the present invention will be explained.
前述したごとくガス処理を行ない吸着材２が被吸着物質
で飽和に達したら、弁６と弁８を開口するとともに連通
管１６から気体（たとえば空気）を流入し、吹き出し口
１５から気体を噴出させる。When the gas treatment is performed as described above and the adsorbent 2 reaches saturation with the adsorbed substance, the valves 6 and 8 are opened, gas (for example, air) is introduced from the communication pipe 16, and the gas is ejected from the outlet 15. .
本操作により、第４図に示したように吸着塔１下部周辺
のブリッジングを起こしやすい個所が気体の噴出流で流
動するので、吸着材２がブリッジングを生ずることがな
い。By this operation, as shown in FIG. 4, the area around the lower part of the adsorption tower 1 where bridging is likely to occur is caused to flow by the jet stream of gas, so that the adsorbent 2 does not cause bridging.
したがって比較的短時間で吸着材２を吸着塔１から排出
することができる。Therefore, the adsorbent 2 can be discharged from the adsorption tower 1 in a relatively short time.
気体の吹き出し管１４に付設する吹き出し口１５につい

に沿って斜め下向きの二方向に気体を噴出できるように
吹き出し口１５を付設することが望ましく、また二方向
の噴出流をそれぞれ扇形状にすると好ましい。To explain in more detail about the blowout port 15 attached to the gas blowout pipe 14, as shown by the arrow in FIG. It is desirable to provide an outlet 15 so that the gas can be ejected, and it is also preferable that the ejected flows in the two directions are fan-shaped.
なお吹き出し口１５から噴出させる気体の流速は、少な
くとも５０ｃｍ／ｓｅｃ以上とすれば充分である。Note that it is sufficient that the flow rate of the gas ejected from the outlet 15 is at least 50 cm/sec or more.
以上説明したように、吸着塔１の直線部とコーン部との
接合部付近に気体の吹き出し管１４を付設し、ここから

果的に吸着材２を排出することができる。As explained above, by attaching the gas blowing pipe 14 near the joint between the straight part and the cone part of the adsorption tower 1 and blowing out the gas from there, the adsorbent 2 can be prevented from bridging. , can be discharged from the adsorption tower 1, so there is no need to make the shape of the cone part elongated with an inclination of more than the angle of repose, as is the case with conventional methods. Just by doing so, the adsorbent 2 can be effectively discharged.
また場合によっては下部コーンの形状を排出管９に向っ
て一方向のみ傾斜させたクサビ形とすることもできる。Further, depending on the case, the shape of the lower cone may be a wedge shape that is inclined in only one direction toward the discharge pipe 9.
なおこの場合は吸着塔１の直線部と一方向に傾斜したコ
ーン部の傾斜面との接合部付近のみに気体の吹き出し管
１４を付設するだけでよい。In this case, it is only necessary to attach the gas blowing pipe 14 near the joint between the straight part of the adsorption tower 1 and the inclined surface of the cone part inclined in one direction.
次に連通管１６から流入させる気体について説明すると
、用いる気体としては加圧空気を用いてもさしつかえな
いが、この場合はコンプレッサー、あるいはブロワ−な
どの気体加圧装置が必要となる。Next, the gas to be introduced from the communication pipe 16 will be explained. Pressurized air may be used as the gas, but in this case, a gas pressurizing device such as a compressor or a blower is required.
ところでガス処理装置には、もともと被処理ガスを送風

を設置しなくともその目的を達成することができる。By the way, since the gas treatment equipment is originally equipped with a blower or the like for blowing the gas to be treated, one end of the communication pipe 16 is connected to the inlet of the gas to be treated by the gas treatment equipment, as shown in FIG. By connecting to the pipe 12, closing the damper valve 11 and opening the valve 17 when the adsorbent 2 is discharged, and allowing the gas to be treated to flow into the communication pipe 16, the purpose can be achieved without installing an extra gas pressurizing device. can be achieved.
