沸石濃縮轉(zhuǎn)輪被分為吸附區(qū)、脫附區(qū)、冷卻區(qū)三個(gè)功能區(qū),沸石分子篩轉(zhuǎn)輪在各個(gè)功能區(qū)域內(nèi)連續(xù)運(yùn)轉(zhuǎn)。 在吸附區(qū):廢氣通過(guò)前置的過(guò)濾器后,送至沸石分子篩轉(zhuǎn)輪的吸附區(qū)。在吸附區(qū)(吸附區(qū)面積為S1 )有機(jī)廢氣中的VOCs被沸石分子篩吸附,未被吸附的廢氣在吸附風(fēng)機(jī)的帶動(dòng)下,直接排人煙囪達(dá)標(biāo)排放。在脫附區(qū):沸石轉(zhuǎn)輪上吸附的VOCs,在脫附區(qū)(脫附區(qū)面積為S2 ) 被高溫逆向脫附、濃縮,脫附溫度約200oC:,濃縮倍數(shù)一般為5 ~ 25倍。濃縮倍數(shù):n = (S1 x V1)/(S2 xV2 ) ,其中 S1/S2 = 10:1 ,V1/V2 = ( 0.5 ~ 2.5 )。脫附氣在脫附風(fēng)機(jī)的帶動(dòng)下進(jìn)人RTO焚化系統(tǒng)。 在冷卻區(qū):為保證高的吸附效率,需對(duì)高溫脫附后的轉(zhuǎn)輪進(jìn)行冷卻。冷卻空氣冷卻轉(zhuǎn)輪吸附材后自身被預(yù)熱,作為脫附氣的源氣,再與來(lái)自RTO燃燒室來(lái)的高溫凈化氣換熱,溫度提升至180 ~ 200oC 后逆向進(jìn)人轉(zhuǎn)輪脫附區(qū)進(jìn)行高溫脫附。 沸石分子篩轉(zhuǎn)輪的設(shè)計(jì)參數(shù)見(jiàn)表2 。
沸石分子篩轉(zhuǎn)輪設(shè)備整體密閉,污染源主要為沸石分子篩更換產(chǎn)生的廢沸石材料,但根據(jù)工程實(shí)際案例運(yùn)營(yíng)情況,吸附材料一般壽命在5 年以上。
蓄熱氧化爐 采用三床式RTO。RTO蓄熱式氧化爐,是在高溫下將可燃廢氣氧化成對(duì)應(yīng)的氧化物和水,從而凈化廢氣,并回收廢氣分解時(shí)所釋放出來(lái)的熱量,廢氣分解效率達(dá)到99% 以上,熱回收效率達(dá)到95% 以上。主體結(jié)構(gòu)由燃燒室、陶瓷填料床和切換閥等組成。根據(jù)客戶實(shí)際需求,選擇不同的熱能回收方式和切換閥方式。建設(shè)單位將調(diào)漆、噴涂廢氣收集后,經(jīng)過(guò)濾除漆霧、吸附濃縮后,引人RTO進(jìn)行焚燒處置。經(jīng)焚燒處理后的廢氣通過(guò)換熱后,廢氣高空排放。RTO可實(shí)現(xiàn)廢氣安全、穩(wěn)定地焚燒,在工作過(guò)程中需定期鼓人新鮮空氣用以維持燃燒,空氣中的氮在高溫條件下氧化會(huì)產(chǎn)生熱力型氮氧化物。根據(jù)文獻(xiàn)記載,熱力型氮氧化物的生成量主要取決于溫度,在相同條件下,氮氧化物的生成量隨溫度增高而增大,當(dāng)溫度低于1350oC時(shí),幾乎不生成熱力型氮氧化物,建設(shè)項(xiàng)目RTO工作溫度約為760 ~ 850oC,在此情況下,熱力氧化器氮氧化物的產(chǎn)生量極少,因此建設(shè)項(xiàng)目廢氣處理系統(tǒng)內(nèi)不設(shè)氮氧化物處理裝置。 蓄熱式焚燒爐的工作原理:將有機(jī)廢氣預(yù)熱至760oC以上,在燃燒室加熱升溫至800oC左右,使廢氣中的碳、氫、氧元素氧化分解成為無(wú)害的CO2和H2O ;氧化時(shí)的高溫氣體的熱量被特制的陶瓷蓄熱體“貯存”起來(lái),用于預(yù)熱新進(jìn)人的有機(jī)廢氣。從而節(jié)省升溫所需要的料消耗,降低運(yùn)行成本。 蓄熱焚燒爐英文名為“Regenerative Thermal Oxidizer”,故簡(jiǎn)稱為“RTO”,它通常由多個(gè)蓄熱室組成。在設(shè)備運(yùn)行前運(yùn)用點(diǎn)燒器加溫把有機(jī)廢氣加熱到800℃以上,從而使廢氣中的VOC在氧化室氧化分解成二氧化碳和水。氧化產(chǎn)生的高溫氣體流經(jīng)特制熱陶瓷,使蓄熱陶瓷升溫而“蓄熱”;此“蓄熱”用于預(yù)熱后續(xù)進(jìn)入的有機(jī)廢氣,從而節(jié)省用于廢氣升溫的燃料;蓄熱室,“放熱立即引入已處理合格的潔凈煙氣的一部分對(duì)該蓄熱室進(jìn)行清掃。每個(gè)蓄熱室依次經(jīng)歷蓄熱放熱清掃等程序,周而復(fù)始,連續(xù)工作。
安居樂(lè)VOC沸石轉(zhuǎn)輪濃縮GRTO裝置簡(jiǎn)介: Zeolite Rotary Concentrator Wheel+ GRTO:
How to treat low concentration with large air flow waste stream? Shanghai Anjule has patent designed solutions with the zeolite concentrators to reduce the air flow of the pollutant and concentrate the VOCs before the RTO treatment. Improve the removal efficiency, reduce the operating cost while meeting the regulations. This is a leading technologies in treating VOCs and HAP.
The process flow for zeolite rotary concentrator wheel+ RTO (RCO)
Anjule technology can be applied to work with the process specifications. For example, emission from coating industrial has the characteristic of high air volume: the waste gas was sent to the G-vortex column to remove particulate. After the dehumidifier process, the waste gas was sent to a specially designed filter before entering the rotary concentrator for VOCs adsorption. The removal efficiency can achieve VOC removal efficiency above 90%. A system fan was installed to release the cleaned air, which is in compliance with the regulations. The air stream then transfer to the RTO for further treatment.
1. Rotary entrance with G-vortex column Anjule G-vortex column has a unique vortex structure, purify and remove the paint organic substance from gas. The advantage: 1. Avoid the blockage of the packing media; reduce the operating cost; and achieve high removal efficiency of VOC substance. Minimize the accumulation of the paint substance0n the rotary and at a result prevent fire hazard.
2. Advance rotary device
Aujule has set up a laboratory and an engineering center for the design of the exhaust gas VOC treatment. The rotary wheels are imported from Japan; the VOC compounds removal rate are measured in a laboratory to ensure the successful treatment for the environmental projects. The advantage of our rotary concentrator: small size, convenience, low pressure lost and work continuously to concentrate low VOC concentration waste gas. The rotary processed gas has a high concentration of VOC with less volume and therefore reduce the amount of the waste gas for the RTO treatment.
3. Safety guarantee Patent designed of Anjule GRTO has put the fire, explosions and other safety factors into fully consideration. The operation of the GRTO is steady, safe and reliable.
4. Advance Technology GRTO control system equipped with software and hardware interlocks, through temperature, pressure responses, the system reacts immediately to the safety control of the system. Effectively,protect the safety of the system . RTO control system uses PLC, installed inside of the control panels; equipped with flame intensity detector, temperature controllers, alarm, reset,0n and off switch, emergency stop, and a recorder; RTO system works seamlessly with the production line without interfering to the existing production.
5. The low operating cost advantage Lower operating cost can be achieved with high VOC concentration in the waste stream. Using a rotary concentrator to reduce the volume of the waste gas is a feasible way in decreasing the cost.
2017年日本雅馬哈電子樂(lè)器天津有限公司上了一套VOCs 治理設(shè)備。設(shè)備通過(guò)環(huán)保驗(yàn)收后,安全、穩(wěn)定運(yùn)行。廢氣源為噴漆,線路板、印刷廢氣,風(fēng)量140000m3/h,濃度進(jìn)口681mg/m3,出口為6.44mg/m3,凈化效率99%,遠(yuǎn)遠(yuǎn)低于天津市DB12/524-2016《工業(yè)企業(yè)揮發(fā)性有機(jī)物排放控制標(biāo)準(zhǔn)》。憑借設(shè)備的優(yōu)秀性能,該項(xiàng)目拿到了天津市環(huán)境保護(hù)專項(xiàng)補(bǔ)貼獎(jiǎng)金叁佰多萬(wàn)元。 沸石轉(zhuǎn)輪的生產(chǎn)產(chǎn)商無(wú)法相信VOCs 治理設(shè)備三年時(shí)間還能保持穩(wěn)定高效的凈化效率,所以專門找人去天津雅馬哈公司測(cè)試,并把樣品拿回東京本部論證。 雅馬哈GRTO設(shè)備如圖 天津雅馬哈工廠沸石轉(zhuǎn)輪+GRTO蓄熱式焚燒爐 日本住友天津公司也使用了GRTO蓄熱式焚燒處理設(shè)備。日本住友天津公司的廢氣主要橡膠硫化廢氣,處理風(fēng)量:10000m3/h;廢氣成分:顆粒物,油霧,氨氣、硫化物、苯系物、非甲烷總烴等。在使用GRTO后,日本住友先后兩次委托獨(dú)立的第三方監(jiān)測(cè)公司分別進(jìn)行了兩天6頻次的監(jiān)測(cè),監(jiān)測(cè)數(shù)據(jù)都滿足了合同約定出口VOCs小于1 mg/m3,且遠(yuǎn)低于天津地方標(biāo)準(zhǔn)60mg/m3。日本本部專門來(lái)人和天津工廠先后采用了手持設(shè)備連續(xù)一周進(jìn)行在線監(jiān)測(cè),數(shù)據(jù)都達(dá)到合同約定標(biāo)準(zhǔn)。隨后,廣州住友和合肥住友分別又上了4套該設(shè)備。
沸石轉(zhuǎn)輪吸附濃縮+ RTO工藝先采用轉(zhuǎn)輪吸附濃縮,降低了 RTO設(shè)備廢氣處理量,使得RTO規(guī)模變小,降低了設(shè)備投資費(fèi)用;盡管有機(jī)廢氣濃度比較低,但經(jīng)濃縮后,有機(jī)廢氣濃度達(dá)到自持濃度以上,所以RTO除了首次開(kāi)機(jī)預(yù)熱需要消耗天然氣(RTO輔助燃料)外,其他時(shí)間RTO輔助加熱系統(tǒng)無(wú)需開(kāi)啟,同時(shí)脫附風(fēng)熱源來(lái)自于有機(jī)廢氣氧化釋放的熱能,系統(tǒng)運(yùn)行費(fèi)用低。沸石轉(zhuǎn)輪濃縮一RTO凈化系統(tǒng)采用PLC全自動(dòng)化控制并配備液晶觸摸顯示屏。控制程序監(jiān)視所有控制器、驅(qū)動(dòng)器、壓力開(kāi)關(guān)、壓力變送器、熱電偶、限位開(kāi)關(guān)、生產(chǎn)線連鎖信號(hào)和儀表連鎖信號(hào)。如發(fā)生任何異常,人機(jī)界面就會(huì)顯示故障信息,然后通過(guò)程序控制采取適當(dāng)動(dòng)作,確保系統(tǒng)的安全。 |
