在橡膠輪胎生產(chǎn)過程中，硫化和煉膠工序均產(chǎn)生工藝廢氣。污染因子為工業(yè)粉塵、惡臭等污染物。雖然污染強度不大，但廢氣排放量大、污染成分復雜多變，尤其是廢氣中惡臭成分對周圍環(huán)境、廠區(qū)環(huán)境造成一定的污染，擾民現(xiàn)象難以避免。

輪胎生產(chǎn)廢氣成分：

輪胎制造廠有害工藝廢氣的主要來源于煉膠車間和硫化車間。廢氣中的主要污染物有：惡臭、炭黑粉塵、顆粒粉塵、甲苯、二甲苯、**苯、乙苯、乙庚烷、非甲烷烴等污染物。廢氣中含有粉塵顆粒物、刺鼻性物質、有害物質等。廢氣排放濃度不高，但廢氣排放量很大，成分又多，污染問題也受到相關部門的重視。橡膠廢氣中含有大量的苯乙烯、笨、甲苯、丁酮、醛、硫化物、氮氧化物等有機廢氣及煙氣。

輪胎生產(chǎn)廢氣治理方法：光催化、吸收法、吸附法、等離子除臭法、催化燃燒法、微生物降解法、掩蔽法、臭氧法等.

1、生物法：設備占地大，投資成本高，處理效率不理想。

2、吸收法：產(chǎn)生二次污染、操作要求高、運行費用較高。

3、等離子法：投資高、運行不穩(wěn)定，多次出現(xiàn)爆炸現(xiàn)象，存在較大安全隱患。

4、燃燒法：處理效果顯著，運行成本較低，安全性較高。

5、光催化：處理效率一般，成本較低，運行費用較低。

橡膠廢氣處理設備工藝簡介：

蓄熱焚燒技術原理：

蓄熱焚燒爐英文名為“Regenerative Thermal Oxidizer”，故簡稱為“RTO”，它通常由多個蓄熱室組成。在設備運行前運用點燒器加溫把有機廢氣加熱到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”用于預熱后續(xù)進入的有機廢氣，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該蓄熱室進行清掃。每個蓄熱室依次經(jīng)歷蓄熱放熱清掃等程序，周而復始，連續(xù)工作。

安居樂VOC沸石轉輪濃縮GRTO裝置簡介:

Zeolite Rotary Concentrator Wheel+ GRTO:

對于低濃度?大風量的VOC污染廢氣，上海安居樂環(huán)保科技股份有限公司推出自主知識產(chǎn)權的GRTO工藝，進一步完善了傳統(tǒng)的VOC濃縮+RTO蓄熱燃燒裝置工藝，可以將低濃度、大風量的污染空氣濃縮為小風量、高濃度的廢氣后進行熱力燃燒處理，效率提升，安全提升，而且可以降低運行成本，實現(xiàn)低成本、高效率VOC尾氣處理達標排放，是行業(yè)領先的有機揮發(fā)性VOC和惡臭HAP廢氣環(huán)保治理工藝。

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.

常規(guī)有機廢氣濃縮轉輪和RTO（RCO）處理流程如下：

The process flow for zeolite rotary concentrator wheel+ RTO (RCO)

安居樂的工藝技術更加貼近廢氣工況，以大風量的噴漆廢氣處理為例：

車間排放有機廢氣通過總管道送至G渦流凈化塔做漆霧顆粒去除處理，后經(jīng)過除霧器，再經(jīng)過專門設計的組合過濾器后，由VOC沸石濃縮轉輪吸附區(qū)吸附，吸附效率為90%以上；排放廢氣由吸附風機抽出，并達標排放；

濃縮轉輪吸附住的有機物，從轉輪脫附區(qū)域脫附出來進入RTO高溫氧化處理

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.

一、轉輪入口G渦流凈化塔

安居樂G渦流洗滌凈化塔采用獨特的渦流結構；凈化去除有機廢氣中漆物，以滿足轉輪入口條件；優(yōu)點：1、不易堵塞，無需更換填料。2、運行成本低。3、漆粒去除效率高，防治漆粒積蓄在轉輪上發(fā)生火災。

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.

二、先進轉輪裝置

2. Advance rotary device

安居樂設有專門的VOC處理實驗室，廢氣治理實驗工程中心，轉輪裝置引進日本，實驗測試具體成分的轉輪效率，保障項目的成功率。轉輪吸附裝置的優(yōu)點體積小、操作方便、壓降低；它可以連續(xù)地將大的廢氣流量處理成濃度足夠低的凈化氣，而解吸出來的氣體則濃度高而流量低，從而進入低風量RTO裝置徹底燃燒。

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.

三、安全性高

安居樂獨家專利設計的GRTO工藝充分考慮了消防、防爆等安全因素，運行穩(wěn)定，安全可靠，工藝完整。

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.

四、技術先進性

GRTO 控制系統(tǒng)設有軟硬體聯(lián)鎖，可通過溫度、壓力等反饋，及時調節(jié)響應聯(lián)動器件，可有效保障系統(tǒng)安全。RTO控制系統(tǒng)采用PLC,安置在控制盤體內；配有火焰強度顯示、高溫控制器、報警、復位、開關機、緊急停機以及記錄儀；RTO系統(tǒng)與產(chǎn)線進行無縫銜接，確保不影響現(xiàn)有工藝及生產(chǎn)。

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.

五、運行費用優(yōu)勢

濃度越高運行成本越低。所以采取合理的技術手段增加有機廢氣進入RTO（RCO）時的濃度，以及減少廢氣處理量是減少RTO（RCO）投資與提高運行效率的有效途徑。

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.
