Conventionally, a horizontal rotating cylindrical suction/desorption device shown in FIG. 1 has been known. In such a device,
The water vapor for desorption was press-fitted from the center of the circle toward the outer circumference. For this reason, there was a problem in that all of the water vapor drain generated in the air supply pipe for desorption is sent into the activated carbon chamber and wets the activated carbon, reducing the adsorption capacity of the activated carbon.
また、この脱着用水蒸気の圧入は、円中心側か

シールが困難であるという問題があつた。 In addition, the steam for desorption is injected from the center of the circle, so the seal becomes a curved seal.
There was a problem that sealing was difficult.
本発明は、このような問題を解決し、脱着用水

The present invention solves these problems and provides a horizontal rotating cylindrical adsorption/desorption device that does not wet the activated carbon with desorption steam and facilitates the sealing mechanism of the steam supply pipe.
本発明は下記の構成からなる。 The present invention consists of the following configuration.

筒式吸脱着装置。 In a horizontal rotating cylindrical adsorption/desorption device in which a horizontal drum uses activated carbon as an adsorbent and has a plurality of radially partitioned adsorption/desorption chambers, a steam supply pipe that can be sealed and detached from the drum side wall and a steam supply pipe to the drum side wall are used. 1. A horizontal rotating cylindrical adsorption/desorption device, comprising a steam receiving portion corresponding to a pipe, and the steam receiving portion is inclined outward or provided with a weir to prevent drain from flowing in.

うことのできる、実用的な横形回転円筒式吸脱着
装置である。 In this device, the steam supply section for desorption to the activated carbon layer is a flat part of the side wall of the drum, so the sealing mechanism is simple, and the activated carbon is not wetted by drainage of steam for desorption, so it can efficiently adsorb and desorb. This is a practical horizontal rotating cylindrical adsorption/desorption device that can perform
本発明を図面によつて説明する。 The present invention will be explained with reference to the drawings.
第１図は、従来知られた横形回転円筒式吸脱着

溶媒を脱着後溶媒含有水蒸気４として排出され、
適宜、溶剤５と水６とを分離し溶剤の回収が行わ
れる。７は冷却器、８はフイルターである。 In the conventionally known device of FIG. 1, in the adsorption zone, solvent-containing air 1 is supplied from the outer periphery of the drum and passes through a layer of activated carbon, the solvent contained therein is adsorbed by the activated carbon and clean air 2 is discharged from the center of the drum. on the other hand,
In the desorption zone, desorption water vapor 3 is supplied from the center, passes through the activated carbon layer, desorbs the solvent adsorbed on the activated carbon, and is then discharged as solvent-containing water vapor 4.
As appropriate, the solvent 5 and water 6 are separated and the solvent is recovered. 7 is a cooler, and 8 is a filter.
このような装置にあつて、活性炭層に水蒸気を
供給する際、水蒸気の供給管の中に溜まつたドレ
ンや、水蒸気が供給管からドラムの脱着ゾーンで
噴出した際に生ずるドレンによつて活性炭を濡ら
し活性炭の吸着能力を低下させる。 In such equipment, when steam is supplied to the activated carbon layer, the activated carbon is removed by condensate accumulated in the steam supply pipe or by condensate generated when steam is ejected from the supply pipe in the desorption zone of the drum. Wetting the activated carbon reduces its adsorption capacity.
更に、このような装置にあつては、蒸気の供給

ル機構が曲面において行われることになり、気密
が困難である。 Furthermore, in such devices, the steam is supplied from the center of the drum and the solvent-containing steam is discharged from the outer periphery of the drum, so the steam sealing mechanism is performed on the curved surface, making it airtight. is difficult.
そこで本発明では、第２図に示す通り、脱着用
水蒸気の供給部をドラムの側壁部に封脱着できる
ように設ける。しかも、供給された水蒸気の噴射
とともに生ずるドレンが活性炭層に達しないよう
に、ドラムの受入部をドラムの外周方向に傾斜し
て設けるか、受入部に堰を設ける。 Therefore, in the present invention, as shown in FIG. 2, a water vapor supply section for desorption is provided on the side wall of the drum so that it can be sealed and desorbed. Furthermore, in order to prevent drainage generated with the injection of the supplied water vapor from reaching the activated carbon layer, the receiving portion of the drum is provided to be inclined toward the outer circumference of the drum, or a weir is provided in the receiving portion.
このようにすると、ドレンは活性炭層に達せ

ラムの外に落ち活性炭を濡らすことはなく、活性
炭の吸着能を損なわれない。 In this way, the drain does not reach the activated carbon layer, and when the steam supply pipe is separated from the side of the drum, it does not fall outside the drum and wet the activated carbon, so that the adsorption ability of the activated carbon is not impaired.

着させる。順次この動作を繰り返す。 FIG. 3 shows a front view of the device of the present invention, which is divided into three parts to form an activated carbon chamber. (The number of divisions is determined by the gas throughput and gas concentration.) In FIGS. 2 and 3, the drum 21 is intermittently rotated by a drive motor. In the case of this figure, it advances in 1/3 rotation increments. The drum is in the A room at positions A and A.
The activated carbon in chamber B adsorbs the solvent in the solvent-containing air. Furthermore, at position C, the activated carbon in chamber C is desorbed. When desorption is complete and the solvent is effectively adsorbed on the activated carbon on the adsorption side, turn the drum 1/3 of a turn, and rotate chamber A with the solvent adsorbed on the activated carbon to the desorption zone C. Move and remove. Repeat this operation sequentially.
脱着ゾーンのウには、ドラムの分割された１室
を密閉する構造を持つた蒸気供給管及び密閉でき
る蓋２３と脱着ガス取出し管及び密閉できる蓋２
８が具備されている。 In the desorption zone C, there are a steam supply pipe and a sealable lid 23 which have a structure to seal one divided chamber of the drum, and a desorption gas extraction pipe and a sealable lid 2.
8 is provided.
脱着すべき部屋がこの定位置にきた時、蓋２３
及び蓋２８が閉じ、部屋は吸着側と遮断され密閉

Then, the lid 28 is closed, and the chamber is sealed off from the suction side.

管より次の工程に送られる。 Steam is then injected into the sealed room through the steam supply pipe. The steam heats the activated carbon layer and desorbs the adsorbed solvent as it passes through the activated carbon layer, and is sent to the next process through the desorption gas take-off pipe.

レンは系外に排出される。 As shown in FIG. 2, the water vapor flow path is placed horizontally. Additionally, the water vapor flow path within the drum is extremely widened compared to conventional devices. The blown steam and steam drain stall in this enlarged flow path, and the steam drain falls downward. (Figure 4a). Since the weir 42 is provided at the back of the flow path, the condensate accumulated in the flow path does not flow into the activated carbon chamber, and when the steam supply pipe 23 is separated in the next process (Fig. 4b) Drainage is then discharged out of the system.

As the fibrous activated carbon, acrylic type, rayon type, phenolic resin type, and pitch type are mainly used.
本発明装置は、有機溶剤の吸脱着に適用できる

According to the present invention, the desorption steam supply pipe is sealed and detached from the side wall of the drum, and the flow path is placed horizontally to prevent steam drain in the desorption steam from flowing into the activated carbon layer. Desorption efficiency is significantly improved.
