いてシリンダーロッドは高濃度の溶剤を含む高温の脱着
ガスに接触することはない。The valve plate 2G reciprocates within its operating length and discharges the desorbed gas when it is in the state shown by the solid line. In this state, the cylinder rod does not come into contact with the high temperature desorption gas containing a high concentration of solvent.
一方、清浄ガスの排出においては、弁板２６は点線の位

め好都合である。On the other hand, when discharging clean gas, the cylinder rod is exposed because the valve plate 26 is at the position indicated by the dotted line, but problems such as corrosion do not occur because the gas in contact is at a low temperature and low 111If. Furthermore, when switching from desorption operation to adsorption operation, the residual desorption gas in the adsorption tower is not directly discharged to the outside of the system, which is convenient.
本発明の溶剤回収装置にて回収される溶剤としては、特
に制限はなく、メタノール、エタノールなどのアルコー
ル類およびアセトンなどのケトン類のほかに、好適には
、塩化メチレンなどの腐蝕性溶剤も含まれる。The solvent recovered by the solvent recovery device of the present invention is not particularly limited, and preferably includes alcohols such as methanol and ethanol, and ketones such as acetone, as well as corrosive solvents such as methylene chloride. It will be done.
本発明装置によると、シリンダーロッドに高温の高濃度
脱着ガスが接触しないため、シリンダー内に溶剤が持ち
込まれることがない。この結果、シリンダー内部品の使
用期間が長くなり、実際上、シリンダーロッドカバー、
シリンダーチューブ等の腐蝕による交換の必要がない。According to the apparatus of the present invention, since the high-temperature, highly concentrated desorption gas does not come into contact with the cylinder rod, no solvent is brought into the cylinder. This results in a longer service life for the cylinder internal parts, and in practice, the cylinder rod cover,
There is no need to replace cylinder tubes etc. due to corrosion.
活性炭に吸着した溶剤の脱着には水蒸気が多く使われる
が、水蒸気脱着の場合にも、脱着ガスを３方切り替え弁
機構２５の下方向に排出することによって、３方切り替
え弁機構２５内で凝縮した少量のドレンも常に排出され
る。このため弁板のパツキンが高温のドレンと接触しな
いため、パツキンの使用期間も長くなる。Water vapor is often used for desorption of solvents adsorbed on activated carbon, but even in the case of steam desorption, the desorption gas can be condensed within the three-way switching valve mechanism 25 by discharging it downward into the three-way switching valve mechanism 25. A small amount of condensate is also constantly discharged. For this reason, the seal of the valve plate does not come into contact with the high-temperature drain, so the period of use of the seal becomes longer.
