It was. Additionally, when the concentration of solvent-containing gas is low, the amount of solvent adsorbed by the activated carbon material becomes extremely large. When desorbing the solvent from the adsorbent, if the solvent is weakly water-soluble, the CO When condensing in the condenser, some of the solvent dissolves in the wastewater, reducing the efficiency of solvent recovery. There was a drawback.

While connecting the gas supply pipe 6, a cooling device 8 is interposed via the second solenoid valve 7. Connect the solvent recovery pipe 9.
【００１０】 ガス吸着用エレメント２は公称比表面積1000ｍ2 ／ｇのピッチ系活性炭素繊維 （Ａ−１０：株式会社アドール製）をフェルト状に加工した活性炭素材としての 活性炭素繊維フェルト（ＦＮ３００ＧＦ１０：関西タール製品株式会社製）を吸 着剤として構成する。[0010] The gas adsorption element 2 is made of activated carbon fiber felt (FN300GF10: Kansai Co., Ltd.) as an activated carbon material obtained by processing pitch-based activated carbon fiber (A-10: manufactured by Ador Co., Ltd.) into a felt shape with a nominal specific surface area of 1000 m 2 /g. (manufactured by Tar Product Co., Ltd.) as an adsorbent.
【００１１】 吸着塔３，３それぞれの上部開口には、エアシリンダ１０によって開閉動作さ れる弁体１１を設け、かつ、その弁体１１により閉じられた状態の空間に接続す るように、ヒータ１２および第３の電磁弁１３を介装した熱風供給管１４を、ガ ス吸着用エレメント２，２それぞれ内まで入込む状態で設ける。図中、１５は、 溶剤を吸着除去した後のガスを排出する排気管を示している。[0011] The upper opening of each of the adsorption towers 3 and 3 is opened and closed by an air cylinder 10. A valve body 11 is provided and connected to a space closed by the valve body 11. The hot air supply pipe 14 equipped with the heater 12 and the third solenoid valve 13 is connected to the The gas adsorption elements 2 and 2 are provided in such a way that they can penetrate into each of them. In the figure, 15 is It shows an exhaust pipe that discharges gas after adsorbing and removing the solvent.
【００１２】 前記溶剤回収管９に、活性炭素材としての粒状活性炭を充填したカートリッジ 式の吸着剤を備えた第２の吸着装置１６を接続する。0012 A cartridge in which the solvent recovery pipe 9 is filled with granular activated carbon as an activated carbon material. A second adsorption device 16 with an adsorbent of formula 1 is connected.
【００１３】 このような構成により、前記第１ないし第３の電磁弁４，４、７，７、１３， １３、および、弁体１１，１１それぞれを背反的に開閉し、一方の吸着塔３に低 濃度の溶剤含有ガスを供給してガス吸着用エレメント２を通過させ、溶剤をガス 吸着用エレメント２に吸着する。そして、このガス吸着用エレメント２が破過に 近い状態、すなわち、ガス吸着用エレメント２のガス排出側で微量の溶剤が検知 された後、他方の吸着塔３に低濃度の溶剤を供給する状態に切換え、それと同時 的に、ほぼ破過状態になった側の吸着塔３に熱風を供給し、ガス吸着用エレメン ト２に吸着された溶剤を加熱脱着してガス吸着用エレメント２を再生し、脱着さ れた高濃度の溶剤を含んだ溶剤含有ガスを冷却装置８に供給し、その冷却により 溶剤含有ガスの温度を低下させ、吸着効率を向上してから第２の吸着装置１６に 供給する。[0013] With such a configuration, the first to third solenoid valves 4, 4, 7, 7, 13, 13 and the valve bodies 11 and 11 are opened and closed in a reverse manner, and one adsorption tower 3 is A concentrated solvent-containing gas is supplied and passed through the gas adsorption element 2, and the solvent is It is adsorbed to the adsorption element 2. Then, this gas adsorption element 2 breaks through. In a similar state, that is, a trace amount of solvent is detected on the gas discharge side of gas adsorption element 2. After that, the state is switched to supplying a low concentration solvent to the other adsorption tower 3, and at the same time Then, hot air is supplied to the adsorption tower 3 on the side that has almost reached the breakthrough state, and the gas adsorption element The gas adsorption element 2 is regenerated by heating and desorbing the solvent adsorbed on the gas adsorption element 2. A solvent-containing gas containing a high concentration of solvent is supplied to the cooling device 8, and by cooling it, After lowering the temperature of the solvent-containing gas and improving the adsorption efficiency, it is transferred to the second adsorption device 16. supply
【００１４】 第１の吸着装置１では、低濃度の溶剤含有ガスから溶剤を吸着するために、そ の吸着時間は数時間から数週間といった長期間の吸着時間を設定できるのに対し て、その吸着した溶剤の脱着に要する時間は数分である。そのため、脱着処理に より脱着溶剤を第２の吸着装置１６に吸着させた後に、吸着剤を適宜交換し、溶 剤を吸着した吸着剤を、セパレータなどの溶剤分離回収装置を備えた別の箇所に 移送し、溶剤を分離回収して吸着剤を再生できる。[0014] In the first adsorption device 1, in order to adsorb the solvent from a low concentration solvent-containing gas, The adsorption time can be set for a long period of time, from several hours to several weeks. Therefore, the time required for desorption of the adsorbed solvent is several minutes. Therefore, in the process of attaching and detaching After the desorption solvent is adsorbed by the second adsorption device 16, the adsorbent is replaced as appropriate and the solvent is removed. The adsorbent that has adsorbed the agent is transferred to another location equipped with a solvent separation and recovery device such as a separator. The adsorbent can be regenerated by transporting and separating and recovering the solvent.
【００１５】 第２の吸着装置１６としては、その溶剤吸着量を第１の吸着装置１の溶剤吸着 量の３倍など、所定倍以上に設定することにより、第２の吸着装置１６の吸着剤 の交換頻度を低減でき、実用上有利である。[0015] As the second adsorption device 16, the amount of solvent adsorbed is the same as that of the first adsorption device 1. By setting the amount to a predetermined amount or more, such as three times the amount, the amount of adsorbent in the second adsorption device 16 can be increased. The replacement frequency can be reduced, which is advantageous in practice.
【００１６】 上述実施例および比較例の吸着処理装置を用いて行った比較実験結果は次の通 りである。[0016] The results of comparative experiments conducted using the adsorption treatment devices of the above examples and comparative examples are as follows. It is.
【００１７】 溶剤含有ガスの発生源から、濃度1ppmのトリクロロエチレンを風量10Ｎm3/min で第１の吸着装置１の一方の吸着塔３に供給してガスの浄化を行い、24時間経過 後に、浄化ガス中に微量のトリクロロエチレンが検出されたため、他方の吸着塔 ３のガス吸着用エレメント２に吸着させる状態に切換えるとともに、溶剤を吸着 した側の吸着塔３に温度 120℃の熱風を供給してガス吸着用エレメント２から溶 剤を脱着し、その脱着溶剤を含む溶剤含有ガスを冷却装置８で40℃に冷却して第 ２の吸着装置１６に供給し、溶剤を吸着させた。これらの吸着塔３に対する脱着 操作を10回繰り返した後、第２の吸着装置１６の吸着剤を回収して、吸着した溶 剤を脱着するとともにセパレータにより比重分離して回収した。Trichlorethylene with a concentration of 1 ppm is supplied from the source of the solvent-containing gas to one adsorption tower 3 of the first adsorption device 1 at an air flow rate of 10 Nm 3 /min to purify the gas, and after 24 hours, the purification is performed. Since a trace amount of trichlorethylene was detected in the gas, the state was changed to adsorption by the gas adsorption element 2 of the other adsorption tower 3, and hot air at a temperature of 120°C was supplied to the adsorption tower 3 on the side that adsorbed the solvent to remove the gas. The solvent was desorbed from the adsorption element 2, and the solvent-containing gas containing the desorbed solvent was cooled to 40° C. by the cooling device 8 and supplied to the second adsorption device 16 to adsorb the solvent. After repeating the desorption operation for these adsorption towers 3 10 times, the adsorbent in the second adsorption device 16 was recovered, and the adsorbed solvent was desorbed and separated by specific gravity using a separator.
【００１８】 その結果、ガス吸着用エレメント２から脱着される溶剤含有ガスの溶剤の平均 濃度は 2000ppmであり、最終的に約 0.8kgのトリクロロエチレンを回収した。[0018] As a result, the average amount of solvent in the solvent-containing gas desorbed from the gas adsorption element 2 The concentration was 2000 ppm, and approximately 0.8 kg of trichlorethylene was finally recovered.
【００１９】 一方、比較例の装置として、前述冷却装置８を介装した溶剤回収管９に代えて 凝縮器を介装した溶剤回収管を用いるとともに、その溶剤回収管に第２の吸着装 置１６に代えてセパレータを接続したものを用い、濃度1ppmのトリクロロエチレ ンを風量10Ｎm3/minで吸着塔３に供給してガスの浄化を行い、24時間経過後に、 浄化ガス中に微量のトリクロロエチレンが検出されたため、加熱水蒸気を供給す る状態に切換え、溶剤の脱着を行ったが、溶剤は弱水溶性であるため、コンデン サーで凝縮する際に排水側に溶解してしまい、トリクロロエチレンを余り回収で きなかった。On the other hand, as a comparative example, a solvent recovery pipe equipped with a condenser is used instead of the solvent recovery pipe 9 equipped with the cooling device 8, and a second adsorption device 16 is installed in the solvent recovery pipe. Instead, a separator was used to purify the gas by supplying trichlorethylene with a concentration of 1 ppm to the adsorption tower 3 at an air flow rate of 10 Nm 3 /min. After 24 hours, a trace amount of trichlorethylene was detected in the purified gas. Therefore, we switched to supplying heated steam and desorbed the solvent, but since the solvent is weakly water-soluble, it dissolved into the waste water when it was condensed in the condenser, and we were not able to recover much trichlorethylene.
【００２０】[0020]
本考案の低濃度溶剤含有ガスの吸着処理装置によれば、第１の吸着装置で吸着 した溶剤を熱風の供給によって脱着するから、従来の加熱水蒸気を用いる場合の ような蒸気発生装置を備えずに済み、設備的に安価に構成できて経済的である。 According to the adsorption treatment device for gas containing a low concentration solvent of the present invention, the first adsorption device adsorbs The solvent is desorbed by supplying hot air, which is different from the conventional method using heated steam. There is no need to provide such a steam generator, and the equipment can be constructed at low cost, making it economical.
【００２１】 また、第１の吸着装置で脱着した溶剤の濃度の高い溶剤含有ガスを第２の吸着 装置に供給して吸着するから、第２の吸着装置での吸着効率を向上でき、第１の 吸着装置に吸着させた溶剤の濃度が低くても、第２の吸着装置で吸着した溶剤の 濃度が高くなり、第２の吸着装置に吸着した溶剤を脱着してセパレータなどで分 離するときに、脱着溶剤に対する排水中への溶解漏出の割合は低下し、溶剤の回 収効率を向上できる。[0021] In addition, the solvent-containing gas with a high concentration of solvent desorbed in the first adsorption device is transferred to the second adsorption device. Since it is supplied to the device and adsorbed, the adsorption efficiency in the second adsorption device can be improved, and the adsorption efficiency in the first adsorption device can be improved. Even if the concentration of the solvent adsorbed by the adsorption device is low, the concentration of the solvent adsorbed by the second adsorption device is When the concentration increases, the solvent adsorbed on the second adsorption device is desorbed and separated using a separator, etc. When separating, the rate of dissolution and leakage into the wastewater for the desorption solvent decreases, and the solvent circulation increases. Yield efficiency can be improved.
【００２２】 更に、低濃度の溶剤に対しては、第１の吸着装置での溶剤吸着を数時間から数 週間行うのに対して第１の吸着装置に対する脱着時間は数分間で済むから、第１ の吸着装置で溶剤の吸着を行っている間に、適宜、第２の吸着装置の吸着剤を交 換し、別の場所で脱着再生して溶剤を回収するといったことができ、セパレータ などの溶剤回収手段を備えずに済み、設備的に一層安価に構成できる利点がある 。[0022] Furthermore, for low-concentration solvents, the solvent adsorption in the first adsorption device can last from several hours to several hours. The desorption time for the first adsorption device is only a few minutes, whereas the desorption time for the first adsorption device is While the solvent is being adsorbed in the first adsorption device, the adsorbent in the second adsorption device may be replaced as necessary. The separator There is no need to provide solvent recovery means such as .
