沸石轉(zhuǎn)輪＋CO設(shè)備運(yùn)行中可能出現(xiàn)的問題

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

　　在環(huán)保政策驅(qū)動下，近年來企業(yè)環(huán)保意識明顯提高，全國各大、中型企業(yè)大多進(jìn)行了環(huán)保設(shè)施的投資。但根據(jù)中央生態(tài)環(huán)保督查組全國各地工業(yè)企業(yè)排污情況督查結(jié)果來看，很多企業(yè)已經(jīng)投資了環(huán)保設(shè)施，卻仍存在超標(biāo)乃至被處罰的情況，其問題何在？事實(shí)上，在VOCs廢氣治理設(shè)備投入運(yùn)行后，也隨之產(chǎn)生新的問題，即對設(shè)備的日常管理維護(hù)和定期維護(hù)保養(yǎng)重視度不夠，亦或維護(hù)管理不專業(yè)。廢氣治理設(shè)備在復(fù)雜工況下長期運(yùn)行，部件的磨損消耗，耗材的耗損等，都直接影響設(shè)備的使用壽命和處理效果，設(shè)備保養(yǎng)不當(dāng)，輕則故障停機(jī)，增加企業(yè)使用維修成本，重則因處理效率下降影響達(dá)標(biāo)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(zhuǎn)輪運(yùn)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(shè)備的良性運(yùn)轉(zhuǎn)，設(shè)備的維護(hù)保養(yǎng)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(zhuǎn)輪設(shè)備為例，沸石轉(zhuǎn)輪設(shè)備可利用吸附-濃縮-脫附三項(xiàng)連續(xù)變溫的吸脫附程序，使低濃度、大風(fēng)量、多組分的有機(jī)廢氣濃縮為高濃度、小風(fēng)量濃縮廢氣，其搭配RTO/CO設(shè)備的治理工藝，具有去除效率高、穩(wěn)定性強(qiáng)、運(yùn)行費(fèi)用合理等優(yōu)勢，目前已廣泛應(yīng)用于涂裝、橡膠、油墨、包裝、電子等行業(yè)；

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(zhuǎn)輪投入運(yùn)行一段時間后，由于預(yù)處理、濾材和運(yùn)維方式等問題，沸石轉(zhuǎn)輪易發(fā)生壓差增大、堵塞/污染等現(xiàn)象，從而導(dǎo)致轉(zhuǎn)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(zhuǎn)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(jìn)入沸石轉(zhuǎn)輪的蜂窩孔道，造成沸石轉(zhuǎn)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(zhuǎn)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(zhuǎn)輪經(jīng)過長年的吸附濃縮，其內(nèi)部會殘留一定量的高沸點(diǎn)物質(zhì)；

(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(fēng)，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(fēng)機(jī)頻率、負(fù)載增大，能耗增加；

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

　　(3)轉(zhuǎn)輪壽命縮短；

(3) Shortened lifespan of the impeller;

　　(4)嚴(yán)重堵塞可能造成設(shè)備停機(jī)，轉(zhuǎn)輪燜燃。

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

　　沸石轉(zhuǎn)輪是廢氣治理系統(tǒng)的核心部件，對使用環(huán)境要求較高，其治理優(yōu)勢明顯，但在整套治理系統(tǒng)內(nèi)成本也占比較高(尤其是進(jìn)口轉(zhuǎn)輪設(shè)備)，如因不注意運(yùn)維管理和維護(hù)造成不良后果，對企業(yè)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(shè)備在運(yùn)行當(dāng)中，企業(yè)應(yīng)充分重視VOCs廢氣設(shè)備的運(yùn)維管理，建立設(shè)備管理機(jī)制，制定運(yùn)行風(fēng)險防范措施，加大設(shè)備日常管理力度，科學(xué)合理地制定設(shè)備的維護(hù)、保養(yǎng)計劃，并組織專業(yè)的運(yùn)維團(tuán)隊，定期對設(shè)備進(jìn)行專業(yè)和科學(xué)的維護(hù)。

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.
