沸石轉輪＋CO設備運行中可能出現的問題

Possible issues that may arise during the operation of zeolite wheel+CO equipment

　　在環保政策驅動下，近年來企業環保意識明顯提高，全國各大、中型企業大多進行了環保設施的投資。但根據中央生態環保督查組全國各地工業企業排污情況督查結果來看，很多企業已經投資了環保設施，卻仍存在超標乃至被處罰的情況，其問題何在？事實上，在VOCs廢氣治理設備投入運行后，也隨之產生新的問題，即對設備的日常管理維護和定期維護保養重視度不夠，亦或維護管理不專業。廢氣治理設備在復雜工況下長期運行，部件的磨損消耗，耗材的耗損等，都直接影響設備的使用壽命和處理效果，設備保養不當，輕則故障停機，增加企業使用維修成本，重則因處理效率下降影響達標排放被處罰。

Driven by environmental policies, in recent years, corporate environmental awareness has significantly increased, and most large and medium-sized enterprises across the country have invested in environmental protection facilities. However, according to the inspection results of the central ecological and environmental protection inspection team on the pollution discharge situation of industrial enterprises across the country, many enterprises have invested in environmental protection facilities, but still have situations of exceeding standards and even being punished. What are the problems? In fact, after the VOCs exhaust gas treatment equipment is put into operation, new problems also arise, namely insufficient attention to the daily management and regular maintenance of the equipment, or unprofessional maintenance management. The long-term operation of exhaust gas treatment equipment under complex working conditions, including wear and tear of components and consumption of consumables, directly affects the service life and treatment effect of the equipment. Improper maintenance of the equipment can lead to minor malfunctions and increased maintenance costs for enterprises, and in severe cases, it can result in penalties for reducing treatment efficiency and affecting emission standards.

　　1、沸石轉輪運行問題及維保的重要性

1. The Operation Problems of Zeolite Wheel and the Importance of Maintenance

　　要保證廢氣治理設備的良性運轉，設備的維護保養很重要！

To ensure the healthy operation of exhaust gas treatment equipment, maintenance and upkeep of the equipment are very important!

　　以沸石轉輪設備為例，沸石轉輪設備可利用吸附-濃縮-脫附三項連續變溫的吸脫附程序，使低濃度、大風量、多組分的有機廢氣濃縮為高濃度、小風量濃縮廢氣，其搭配RTO/CO設備的治理工藝，具有去除效率高、穩定性強、運行費用合理等優勢，目前已廣泛應用于涂裝、橡膠、油墨、包裝、電子等行業；

Taking zeolite rotary equipment as an example, the zeolite rotary equipment can use three continuous temperature changing adsorption desorption procedures of adsorption concentration desorption to concentrate low concentration, high air volume, and multi-component organic waste gas into high concentration and low air volume concentrated waste gas. Its treatment process, combined with RTO/CO equipment, has advantages such as high removal efficiency, strong stability, and reasonable operating costs. It has been widely used in industries such as painting, rubber, ink, packaging, and electronics;

　　沸石轉輪投入運行一段時間后，由于預處理、濾材和運維方式等問題，沸石轉輪易發生壓差增大、堵塞/污染等現象，從而導致轉輪處理效率下降。

After the zeolite impeller is put into operation for a period of time, due to issues such as pre-treatment, filter materials, and operation and maintenance methods, the zeolite impeller is prone to increased pressure difference, blockage/pollution, and other phenomena, resulting in a decrease in the efficiency of the impeller treatment.

　　沸石轉輪堵塞主要有以下原因：

The main reasons for zeolite wheel blockage are as follows:

　　(1) 粉塵等進入沸石轉輪的蜂窩孔道，造成沸石轉輪堵塞；

(1) Dust and other substances enter the honeycomb channels of the zeolite wheel, causing blockage of the zeolite wheel;

　　(2)沸石轉輪長時間使用后，一些廢氣成分可能會堵塞沸石通道；

(2) After prolonged use of the zeolite wheel, some exhaust gas components may block the zeolite channel;

　　(3)沸石轉輪經過長年的吸附濃縮，其內部會殘留一定量的高沸點物質；

(3) After years of adsorption and concentration, a certain amount of high boiling substances will remain inside the zeolite wheel;

　　(1) 影響通風，吸附效率降低，VOC排放濃度升高；

(1) Affects ventilation, reduces adsorption efficiency, and increases VOC emission concentration;

　　(2)風機頻率、負載增大，能耗增加；

(2) The increase in fan frequency and load leads to an increase in energy consumption;

　　(3)轉輪壽命縮短；

(3) Shortened lifespan of the impeller;

　　(4)嚴重堵塞可能造成設備停機，轉輪燜燃。

(4) Severe blockage may cause equipment shutdown and rotor burnout.

　　沸石轉輪是廢氣治理系統的核心部件，對使用環境要求較高，其治理優勢明顯，但在整套治理系統內成本也占比較高(尤其是進口轉輪設備)，如因不注意運維管理和維護造成不良后果，對企業而言損失明顯。

The zeolite impeller is the core component of the exhaust gas treatment system, which has high requirements for the usage environment and obvious treatment advantages. However, the cost within the entire treatment system is also relatively high (especially for imported impeller equipment). If adverse consequences are caused by not paying attention to operation and maintenance management and maintenance, it will cause significant losses to the enterprise.

　　因此廢氣治理設備在運行當中，企業應充分重視VOCs廢氣設備的運維管理，建立設備管理機制，制定運行風險防范措施，加大設備日常管理力度，科學合理地制定設備的維護、保養計劃，并組織專業的運維團隊，定期對設備進行專業和科學的維護。

Therefore, in the operation of waste gas treatment equipment, enterprises should fully attach importance to the operation and maintenance management of VOCs waste gas equipment, establish equipment management mechanisms, formulate operational risk prevention measures, increase daily equipment management efforts, scientifically and reasonably develop equipment maintenance and upkeep plans, and organize professional operation and maintenance teams to regularly maintain the equipment professionally and scientifically.
