201217040 六、發明說明： 【發明所屬之技術領域】 本發明係有關一種流體化浮動床溶劑淨化系統之節能 裝置及方法，尤指一種當流體化浮動床排放端之溶劑濃度 低於排放標準時，則令吸附材於流體化浮動床進行循環吸 附程序’而暫停進行脫附程序之設計者。 【先前技術】 按，利用高孔隙率、高比表面積之吸附材，藉由吸附 作用去除揮發性有機溶劑（Vo i at i i e 〇rgan i c c⑽p〇unds， VOCs)之吸附法淨化技術，一般多使用固定床的吸附系統； 而固定床吸附系統係以兩塔或多塔批式操作方式，進行廢 氣的吸附及吸附飽和後之吸附材料再生，唯在遇有高反應 性的VOCs處理時，常因被吸附之化學品於吸附時與吸附材 產生觸媒氧化放熱反應（例如嗣類與活性碳吸附材），導致 固定床内部散熱不佳而大量熱聚集，進而發生碳床著火或 爆炸問題；於是，為了改善固定床吸附系統的缺點，而發 展出一種吸附材流體化之溶劑淨化系統。 次按’第一圖所示為一種習知吸附材流體化浮動床溶 劑淨化系統，其令廢氣以廢氣風機（13)送入流體化浮動床 (10)的底部，而廢氣氣流藉氣流分散板（12)分散後，乃與 由上落下的吸附材（30)接觸’即可成為淨化氣體並從塔頂 排放；其中’流體化浮動床（1 〇 )的内部以多孔板（11)分隔 成數層，吸附材（30)由流體化浮動床（1〇)頂端落下，而在 多孔板（11)的上方形成浮動層，並沿著多孔板（11) 一層一 201217040 層的開口部落下，當吸附材（30)與含有VOCs的廢氣接觸 時，將廢氣中的VOCs吸附於吸附材（30)的孔洞内，廢氣即 變成淨化氣體排放。 再按，當吸附材（30)落至流體化浮動床（10)底部之貯 槽（14)後，乃藉吸附材吸脫附輸送裝置（20)之第一輸送氣 源（22)，以第一氣源管（232)與第二氣源管（272)送出空氣 或氮氣形成推送力，經吸附出料管（21)、第一下輸送轉運 ' 器（23)、第一輸送轉運管（231)、第一上輸送轉接器（24)與 脫附進料管（25)送至脫附塔（40)之頂端，進行脫附再生之 # 工作；脫附再生後的吸附材（30)則以脫附出料管（26)、第 二下輸送轉運器（27)、第二輸送轉運管（271)、第二上輸送 轉接器（28)與吸附進料管（29)送回流體化浮動床（10)的頂 端。 接著，待再生之吸附材（30)乃在脫附塔（40)慢慢往下 流動，並經由脫附熱源（42)加熱，再由脫附塔（40)下方之 脫附氣源（43)吹入氮氣與吸附材（30)接觸，將吸附材（30) 中的VOCs脫附；經加熱脫附後的吸附材（30)再經脫附塔（40) φ 底部冷卻後，由前述之輸送過程送回流體化浮動床（10)上 端，再度吸收VOCs ;而脫附出來的高濃度廢氣，則以脫附 氮氣載送流經脫附氮氣輸出管（44)攜帶至冷凝器（46)冷 凝，冷凝後之VOCs液體由回收槽（47)回收，冷凝後之脫附 乾淨氮氣乃由脫附氮氣輸入管（45)循環輸入脫附塔（40); ' 此外，脫附出來的高濃度廢氣亦可藉由焚化爐燃燒淨化， • 但因脫附後之淨化（冷凝或焚化）程序，非為本案之專利標 的，乃不再詳述。 201217040 然而，由於前述之習知吸附材流體化浮動床溶劑淨化 系統，因其讓吸附材（30)由流體化浮動床（1〇)頂端落至底 部貯槽後，隨即藉吸附材吸脫附輸送裝置（2〇)送至脫附塔 (40)之頂端，進行脫附再生之工作，再送回流體化浮動床 (10)頂端，而致使吸附材（30)循環進行吸附與脫附程序； 於是，若廢氣中僅含有低濃度溶劑，吸附材（3〇)由流體化 浮動床（10)頂端落至底部貯槽之單次吸附程序，乃僅能吸 附到少量之溶劑，吸附材（30)尚未吸附飽和就必須進行後 續之脫附及冷凝回收程序，致使運轉所耗費之能源與所處 理之溶劑廢氣濃度尚低無關，並無法於處理低濃度溶劑廢 氣時相對節能。 【發明内容】 本發明之主要目的，係欲解決先前技術無法於處理低 濃度溶劑廢氣時相對節能之問題，而具有處理低濃度溶劑 廢氣時得以相對節能之功效。 為達上述功效，本發明節能裝置之結構特徵，係包括 有： 一流體化浮動床，讓吸附材由頂端落至底部而吸附廢 氣中之溶劑； 一脫附塔，讓吸附材由頂端落至底部而將所吸附之溶 劑加熱脫附； 一吸附材吸脫附輸送裝置，將落至該流體化浮動床底 部之吸附材輸送至該脫附塔頂端’且將落至該脫附塔底部 之吸附材輸送至該流體化浮動床頂端； 一吸附材循環吸附輸送裝置，將落至該流體化浮動床 201217040 底部之吸附材輸送至該流體化浮動床頂端；以及 一控制單元’令該吸附材吸脫附輸送裝置與該吸附材 循環吸附輪送裝置之一進行運轉者。 此外，該吸附材吸脫附輸送裝置包括有：第一輸送氣 源、第一下輸送轉運器、第一上輸送轉接器、第二下輸送 轉運器、第二上輸送轉接器、連結該流體化浮動床底部與 第一下輸送轉運器之吸附出料管、連結第一下輸送轉運器 • 與第一上輸送轉接器之第一輸送轉運管、連結第一上輸送 轉接器與該脫附塔頂端之脫附進料管、連結該脫附塔底部 • 與第二下輸送轉運器之脫附出料管、連結第二下輸送轉運 器與第二上輸送轉接器之第二輸送轉運管、連結第二上輸 送轉接器與該流體化浮動床頂端之吸附進料管、連結該第 一輸送氣源與第一下輸送轉運器之第一氣源管以及連結該 第一輸送氣源與第二下輸送轉運器之第二氣源管。 再者’該吸附材循環吸附輸送裝置包括有：第一輸送 氣源、第三下輸送轉運器、第三上輸送轉接器、連結該流 體化浮動床底部與第三下輸送轉運器之循環吸附出料管、 • 連結第二下輸送轉運器與第三上輸送轉接器之第三輸送轉 運S連結第二上輸送轉接器與該流體化浮動床頂端之循 環吸附進料管以及連結該第一輸送氣源與第三下輸送轉運 器之第二氣源管；而該控制單元於該流體化浮動床排放端 設置有溶劑濃度偵測器，且於第一氣源管、第二氣源管及 第二氣源管各別設置有第一關斷閥、第二關斷閥及第三關 • 斷閥，並將該溶劑濃度偵測器、第一關斷閥、第二關斷閥 及第三關斷閥連結至一控帝j器，當排放端《溶劑濃度低於 201217040 排放標準時，該控制器遂令第三關斷閥打開且令第一關斷 閥及第二關斷閥關斷，而當排放端之溶劑濃度觸及排放標 準時’該控制器則令第三關斷閥關斷且令第一關斷閥及第 二關斷閥打開。 再一，該吸附材循環吸附輸送裝置包括有：第一輸送 氣源、第三下輸送轉運器、第三上輸送轉接器、連結該流 體化浮動床底部與第三下輸送轉運器之循環吸附出料管、 連結第三下輸送轉運器與第三上輸送轉接器之第三輸送轉 運管、連結第三上輸送轉接器與該流體化浮動床頂端之循 • 環吸附進料管以及連結該第一輸送氣源與第三下輸送轉運 器之第三氣源管；而該控制單元根據溶劑用量與吸附材吸 附能力所估算出之吸附材吸附飽和時間，且於第一氣源 官、第二氣源管及第三氣源管各別設置有第一關斷閥、第 二關斷閥及第三關斷閥，並將第一關斷閥、第二關斷閥及 第二關斷閥連結至一控制器，當吸附材吸附飽和時間到達 之刖’該控制器遂令第三關斷閥打開且令第一關斷閥及第 二關斷閥關斷，而當吸附材吸附飽和時間到達之際，該控 • 制器則令第三關斷閥關斷且令第一關斷閥及第二關斷閥打 開。 另者’該吸附材循環吸附輸送裝置包括有：連結第一 上輸送轉接器與該流體化浮動床頂端之循環吸附進料管； 而該控制單元於該流體化浮動床排放端設置有溶劑濃度摘 測器’且於第二氣源管、循環吸附進料管及脫附進料管各 ' 別設置有第二關斷閥、第四關斷閥及第五關斷閥，並將該 溶劑濃度偵測器、第二關斷閥、第四關斷閥及第五關斷閥 201217040 連結至一控制器，當排放端之溶劑濃度低於排放標準，該 控制器遂令第四關斷閥打開且令第二關斷閥及第五關斷閥 關斷，而當排放端之溶劑濃度觸及排放標準時，該控制器 則令第四關斷閥關斷且令第二關斷閥及第五關斷閥打開。 另―，該吸附材循環吸附輸送裝置包括有：連結第一 . 上輸送轉接器與該流體化浮動床頂端之循環吸附進料管； 而該控制單元根據溶劑用量與吸附材吸附能力所估算出之 吸附材吸附飽和時間，且於第二氣源管、循環吸附進料管 及脫附進料管各別設置有第二關斷閥、第四關斷閥及第五 • 關斷閥，並將第二關斷閥、第四關斷閥及第五關斷閥連結 至一控制器，當吸附材吸附飽和時間到達之前，該控制器 遂令第四關斷閥打開且令第二關斷閥及第五關斷閥關斷， 而當吸附材吸附飽和時間到達之際，該控制器則令第四關 斷閥關斷且令第二關斷閥及第五關斷閥打開。 又’該吸附材循環吸附輸送裝置包括有：第二輸送氣 源、第三下輸送轉運器、第三上輸送轉接器、連結該流體 化浮動床底部與第三下輸送轉運器之循環吸附出料管、連 • 結第三下輸送轉運器與第三上輸送轉接器之第三輸送轉運 管、連結第二上輸送轉接器與該流體化浮動床頂端之循環 吸附進料管以及連結該第二輸送氣源與第三下輸送轉運器 之第四氣源管；而該控制單元於該流體化浮動床排放端設 置有溶劑濃度偵測器’並將該溶劑濃度偵測器、第一輸送 氣源及第二輸送氣源連結至一控制器，當排放端之溶劑濃 • 度低於排放標準時’該控制器遂令第二輸送氣源送氣且令 第一輸送氣源關閉，而當排放端之溶劑濃度觸及排放標準 201217040 時，該控制器則令第二輸送氣源關閉且令第一輸送氣源送 氣。 又一 ’該吸附材循環吸附輸送裝置包括有：第二輸送 氣源、第三下輸送轉運器'第三上輸送轉接器、連結該流 體化浮動床底部與第三下輸送轉運器之循環吸附出料管、 連結第二下輸送轉運器與第三上輸送轉接器之第三輸送轉 運管、連結第三上輸送轉接器與該流體化浮動床頂端之循 環吸附進料管以及連結該第二輸送氣源與第三下輸送轉運 器之第四氣源管；而該控制單元根據溶劑用量與吸附材吸 鲁 附能力所估算出之吸附材吸附飽和時間，並將第一輸送氣 源及第二輸送氣源連結至一控制器，當吸附材吸附飽和時 間到達之前，該控制器遂令第二輸送氣源送氣且令第一輸 送氣源關閉，而當吸附材吸附飽和時間到達之際，該控制 器則令第二輸送氣源關閉且令第一輸送氣源送氣。 然而，本發明之第一種節能方法，係包括有下列步驟： a) .偵測流體化浮動床排放端之溶劑濃度； b) .當流體化浮動床排放端之溶劑濃度低於排放標準 ❿ 肖’令吸附材於流體化浮動床進行循環吸附程序，而暫停 進行脫附程序；以及 c) .當流體化浮動床排放端之溶劑濃度觸及排放標準 時7吸附材停止於流體化浮動床進行循環吸附程序，而 開始進行脫附程序者。 再者，本發明之第二種節能方法，係包括有下列步驟： a).根據溶劑用量與吸附材吸附能力估算出吸附材吸 附飽和時間； 201217040 b) .當吸附材吸附飽和時間到達之前，令吸附材於流體 化浮動床進行循環吸附程序，而暫停進行脫附程序；以及 c) .當吸附材吸附飽和時間到達之際，令吸附材停止於 流體化浮動床進行循環吸附程序，而開始進行定時之脫附 程序者。 【實施方式】 首先，請參閱第一圖所示，常見之流體化浮動床溶劑 淨化系統，係包括有：一流體化浮動床（10)，讓吸附材（30) 由頂端落至底部而吸附廢氣中之溶劑；一脫附塔（40)，讓 吸附材（30)由頂端落至底部而將所吸附之溶劑加熱脫附； 一吸附材吸脫附輸送裝置（20)，將落至該流體化浮動床（10) 底部之吸附材（30)輸送至該脫附塔（40)頂端，且將落至該 脫附塔（40)底部之吸附材（30)輸送至該流體化浮動床（10) 頂端。 再者，該吸附材吸脫附輸送裝置（20)係包括有：第一 輸送氣源（22)、第一下輸送轉運器（23)、第一上輸送轉接 器（24)、第二下輸送轉運器（27)、第二上輸送轉接器（28)、 連結該流體化浮動床（10)底部與第一下輸送轉運器（23)之 吸附出料管（21)、連結第一下輸送轉運器（23)與第一上輸 送轉接器（24)之第一輸送轉運管（231)、連結第一上輸送轉 接器（24)與該脫附塔（40)頂端之脫附進料管（25)、連結該 脫附塔（40)底部與第二下輸送轉運器（27)之脫附出料管 (26)、連結第二下輸送轉運器（27)與第二上輸送轉接器（28) 之第二輸送轉運管（271)、連結第二上輸送轉接器（28)與該 流體化浮動床（10)頂端之吸附進料管（29)、連結該第一輸 •ha. 嫌 -10 - 201217040 送氣源（22)與第一下輸送轉運器（23)之第一氣源管（232) 以及連結該第一輸送氣源（22)與第二下輸送轉運器（27)之 第二氣源管（272)。 然而，請參閱第二圖所示’本發明節能裝置之第一實 施例，係於前述之流體化浮動床溶劑淨化系統，進一步設 置一吸附材循環吸附輸送裝置（5〇a)以及一控制單元 (60a);其中’該吸附材循環吸附輸送裝置（5〇a)包括有： 第一輸送氣源（22，與該吸附材循環吸附輸送裝置之輸送氣 源為同一）、第三下輸送轉運器（51)、第三上輸送轉接器 • (52)、連結該流體化浮動床（10)底部與第三下輸送轉運器 (51)之#環吸附出料管（53)、連結第三下輸送轉運器（51) 與第三上輸送轉接器（52)之第三輸送轉運管（54)、連結第 二上輸送轉接器（52)與該流體化浮動床（1〇)頂端之循環吸 附進料管（55a)以及連結該第一輸送氣源（22)與第三下輸 送轉運器（51)之第三氣源管（56)，俾以將落至該流體化浮 動床（10)底部之吸附材（30)輸送至該流體化浮動床頂端 (10)。 # 又’該控制單元（6〇a)於該流體化浮動床（1〇)排放端設 置有溶劑濃度偵測器（61)，且於第一氣源管（232)、第二氣 源官（272)及第三氣源管（56)各別設置有第一關斷閥 (62)、第二關斷閥（63)及第三關斷閥（64)，並將該溶劑濃 度偵測器（61)、第一關斷閥（62)、第二關斷閥（63)及第三 關斷閥（64)連結至一控制器（65);藉此，當排放端之溶劑 浪度低於排放標準時，該控制器（65)遂令第三關斷閥（64) 打開且令第一關斷閥（62)及第二關斷閥（63)關斷，而當排201217040 VI. Description of the Invention: [Technical Field] The present invention relates to an energy-saving device and method for a fluidized floating bed solvent purification system, in particular, when the solvent concentration at the discharge end of the fluidized floating bed is lower than the emission standard, The designer of the desorption process is suspended while the adsorbent material is subjected to a cyclic adsorption process in a fluidized floating bed. [Prior Art] According to the adsorption method for removing volatile organic solvents (Vo i at iie 〇rgan ic c(10) p〇unds, VOCs) by adsorption materials with high porosity and high specific surface area, generally used The adsorption system of the fixed bed; and the fixed bed adsorption system uses the two-stage or multi-tower batch operation mode to carry out the adsorption of the exhaust gas and the regeneration of the adsorbed material after the adsorption saturation, only in the case of the treatment of highly reactive VOCs, often When the adsorbed chemical adsorbs and reacts with the adsorbent material, it generates a catalytic oxidation exothermic reaction (for example, a hydrazine and an activated carbon adsorbing material), resulting in poor heat dissipation inside the fixed bed and a large amount of heat accumulation, thereby causing a problem of ignition or explosion of the carbon bed; In order to improve the shortcomings of the fixed bed adsorption system, a solvent purification system for fluidizing the adsorbent material has been developed. Pressed in the first figure as a conventional fluidized fluidized bed cleaning solvent purification system, which allows the exhaust gas to be sent to the bottom of the fluidized floating bed (10) by the exhaust fan (13), and the exhaust gas flow is dispersed by the airflow dispersion plate. (12) After dispersion, it is contacted with the adsorbent material (30) falling down to become a purge gas and discharged from the top of the tower; wherein the inside of the 'fluidized floating bed (1 〇) is divided into several by a perforated plate (11) The layer, the adsorbent material (30) is dropped from the top of the fluidized floating bed (1〇), and a floating layer is formed above the porous plate (11), and along the perforated plate (11), a layer of 201217040 layer of the opening tribe, when When the adsorbent (30) is in contact with the exhaust gas containing VOCs, the VOCs in the exhaust gas are adsorbed into the pores of the adsorbent (30), and the exhaust gas is discharged into the purge gas. Pressing again, after the adsorbent material (30) falls to the storage tank (14) at the bottom of the fluidized floating bed (10), the first transport gas source (22) of the adsorbing material (20) is sucked and desorbed by the adsorbing material, A gas source tube (232) and a second gas source tube (272) send air or nitrogen to form a pushing force, through the adsorption discharge tube (21), the first lower delivery transporter (23), and the first transport transport tube ( 231), the first upper conveying adapter (24) and the desorption feeding tube (25) are sent to the top end of the desorption tower (40) to perform desorption regeneration # work; desorption and regeneration of the adsorbent material (30) And then the desorption discharge pipe (26), the second lower conveying conveyor (27), the second conveying transfer pipe (271), the second upper conveying adapter (28) and the adsorption feeding pipe (29) The top of the fluidized floating bed (10) is fluidized. Next, the adsorbent (30) to be regenerated is slowly flowed down in the desorption column (40), heated by the desorption heat source (42), and then desorbed by the desorption tower (40) (43). Blowing nitrogen into contact with the adsorbent (30) to desorb the VOCs in the adsorbent (30); the adsorbent (30) after desorption by heating is cooled by the bottom of the desorption column (40) φ The conveying process is sent back to the upper end of the fluidized floating bed (10) to absorb the VOCs again; and the desorbed high-concentration exhaust gas is carried by the desorbed nitrogen carrier through the desorbed nitrogen output pipe (44) to the condenser (46). Condensation, the condensed VOCs liquid is recovered from the recovery tank (47), and the condensed desorbed clean nitrogen is circulated into the desorption column (40) by the desorption nitrogen inlet pipe (45); ' In addition, the desorbed high Concentrated waste gas can also be purified by incinerator combustion. • However, the purification (condensation or incineration) process after desorption is not the patent of this case and will not be described in detail. 201217040 However, due to the aforementioned conventional fluidized fluidized bed cleaning system, the adsorbent material (30) is dropped from the top of the fluidized floating bed (1〇) to the bottom storage tank, and then adsorbed and desorbed by the adsorbent material. The device (2〇) is sent to the top end of the desorption column (40) for desorption regeneration, and then sent back to the top of the fluidized floating bed (10), so that the adsorption material (30) is circulated for adsorption and desorption procedures; If the exhaust gas contains only a low concentration of solvent, the adsorption material (3〇) is dropped from the top of the fluidized floating bed (10) to the bottom storage tank. Only a small amount of solvent can be adsorbed, and the adsorbent material (30) has not yet been adsorbed. The adsorption saturation requires a subsequent desorption and condensation recovery procedure, so that the energy consumed by the operation is not related to the concentration of the solvent exhaust gas being treated, and it is not relatively energy-efficient when dealing with low-concentration solvent exhaust gas.
