ための、繊維状活性炭を吸着材とした吸脱着装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an organic substance adsorption/desorption device using fibrous activated carbon as an adsorbent. More specifically, the present invention relates to an adsorption/desorption device using fibrous activated carbon as an adsorbent for recovering organic solvents such as methylene chloride, trichloroethylene, tetrachloroethylene, methyl alcohol, and acetone and effectively recycling the adsorbent.
繊維状活性炭（以下ACFと記す）は、低濃度
における吸着機能に優れた吸着材として知られて
おり、この吸着材を用いた有機溶剤の吸脱着装置
が提案されている。 Fibrous activated carbon (hereinafter referred to as ACF) is known as an adsorbent with excellent adsorption function at low concentrations, and an organic solvent adsorption/desorption device using this adsorbent has been proposed.
例えばACFを支持体に固定し又は自己支持に
て円筒状に構成し、罐体内にたて型に配設した装
置が特開昭51−38278号公報にて提案されている。
この装置によると、円筒状に構成したACF吸着
素子の上部開口部から筒内に脱着用スチームを噴
出するように構成されている。 For example, JP-A-51-38278 proposes a device in which an ACF is fixed to a support or self-supported in a cylindrical shape and arranged vertically within a housing.
According to this device, the desorption steam is ejected into the cylinder from the upper opening of the ACF adsorption element configured in a cylindrical shape.
このような装置によると、筒状ACF吸着素子
の下部は、スチームの噴出口に遠く位置し、温度
も低く、ぬれたACF層はスチームを通し難い。
更に筒体の下部に当るため、スチームによる脱着
後のACFの含水率が高くなりやすい。 According to such a device, the lower part of the cylindrical ACF adsorption element is located far from the steam outlet and has a low temperature, making it difficult for steam to pass through the wet ACF layer.
Furthermore, since it hits the lower part of the cylinder, the moisture content of the ACF tends to increase after it is desorbed by steam.
一方、ACFの含水率はACFの吸着能力に大き
く影響し、含水率が高くなると、吸着能力は極端
に低くなる。特に前記したような有機溶剤は水分

出口を設けた装置においては、ACF吸着素子の
吸着能が充分に生かされていない。 On the other hand, the water content of ACF greatly affects the adsorption capacity of ACF, and as the water content increases, the adsorption capacity becomes extremely low. In particular, organic solvents such as those mentioned above are easily affected by moisture. This is illustrated in Figure 1. Figure 1 shows the relationship between the moisture content of ACF and the amount of methylene chloride adsorbed when ACF is used as an adsorbent. Therefore, the above-mentioned cylindrical shape
In devices in which a desorption steam outlet is provided in the upper opening of the ACF adsorption element, the adsorption capacity of the ACF adsorption element is not fully utilized.
本発明者等は、このような問題について検討の
結果、脱着時のスチームがACFの含水率を高く
せず、従つてACFの吸着素子の吸着能を損わな
い装置を見出すに到つた。 As a result of studying these problems, the present inventors have found an apparatus in which the steam during desorption does not increase the moisture content of ACF and therefore does not impair the adsorption ability of the ACF adsorption element.
すなわち、本発明は、各々に弁機構を備えた、

A fibrous activated carbon adsorption element having a cylindrical shape is vertically arranged in a case having a gas supply port for the gas to be treated, a clean gas outlet, a steam outlet for desorption, and a steam outlet containing the gas to be desorbed. This is an organic matter adsorption/desorption device characterized in that a steam outlet is provided toward a lower side wall within the adsorption element.

有効に活用することができる。 In this type of device, the desorption steam that is ejected is ejected directly to the lower part of the cylindrical ACF adsorption element where the moisture content is most likely to be high, so the adsorption ability of the ACF is not damaged by moisture. You can use it effectively without having to worry about it.
