Charcoal adsorption, as the most commonly used method for enterprise waste gas treatment and the most common method for handling high air volume and low concentration VOCs, plays a very important role in VOC control and emission reduction. However, in daily inspections, it was found that enterprises generally have problems such as long-term failure to replace activated carbon or failure to properly open facilities, severe dampness or damage to activated carbon, use of inferior carbon, and air leakage in the activated carbon box, resulting in the inability of adsorption devices to function effectively.

規(guī)范運維活性炭處理設(shè)施，不僅有助于企業(yè)廢氣達(dá)標(biāo)排放，更有助于降低生產(chǎn)經(jīng)營風(fēng)險，避免被管理部門執(zhí)法處罰。提醒各企業(yè)務(wù)必重視定期檢查活性炭狀態(tài)。發(fā)現(xiàn)活性炭孔隙堵塞或表面黏附，應(yīng)要立即更換。

Standardizing the operation and maintenance of activated carbon treatment facilities not only helps enterprises meet the emission standards, but also helps to reduce production and operation risks and avoid being punished by management departments for law enforcement. Remind all businesses to pay attention to regularly checking the status of activated carbon. If the pores of activated carbon are blocked or the surface adheres, it should be replaced immediately.

更換下來的廢活性炭屬危險廢物，應(yīng)當(dāng)密閉貯存，交由具備危廢處置資質(zhì)的企業(yè)依法進(jìn)行處置。

The replaced waste activated carbon belongs to hazardous waste and should be stored in a sealed manner, and handed over to enterprises with hazardous waste disposal qualifications for disposal in accordance with the law.

活性炭吸附設(shè)備失效的5大常見原因：

Five common reasons for the failure of activated carbon adsorption equipment:

1.活性炭長時間未更換、發(fā)白

1. Activated carbon has not been replaced or turned white for a long time

2.活性炭附著顆粒物、油漬、水

2. Activated carbon adheres to particles, oil stains, and water

3.活性炭未完全裝填

3. Activated carbon not fully loaded

4.廢氣溫度超過50℃導(dǎo)致活性炭失活

4. Deactivation of activated carbon due to exhaust gas temperature exceeding 50 ℃

5.活性炭箱體漏風(fēng)

5. Air leakage in the activated carbon box

二、企業(yè)應(yīng)如何規(guī)范使用活性炭

2、 How Enterprises Should Standardize the Use of Activated Carbon

活性炭的不當(dāng)維護(hù)可能會嚴(yán)重影響治污設(shè)施的處理效果，因此企業(yè)在使用活性炭治理廢氣時，需要注重規(guī)范意識，加強維護(hù)管理，并牢記活性炭的使用“三個要”：

Improper maintenance of activated carbon may seriously affect the treatment efficiency of pollution control facilities. Therefore, when using activated carbon for waste gas treatment, enterprises need to pay attention to standardization awareness, strengthen maintenance management, and bear in mind the "three essentials" of using activated carbon:

首先，企業(yè)要掌握活性炭的質(zhì)量鑒別技巧。采用“一稱、二看、三試”的簡單方法，快速地評估活性炭的質(zhì)量，篩選出符合要求的活性炭，并充分填充，以確保箱體不出現(xiàn)空隙。

Firstly, enterprises need to master the quality identification techniques of activated carbon. Using a simple method of "weighing, inspecting, and testing", quickly evaluate the quality of activated carbon, screen out qualified activated carbon, and fully fill it to ensure that there are no gaps in the box.

其次，通過記錄活性炭的運營和維護(hù)信息，例如箱體規(guī)模、處理風(fēng)量、更換活性炭填充量及其碘值，以及設(shè)施的運維和耗材更換情況，從而建立廢氣處理設(shè)施運維臺賬。

Secondly, by recording the operation and maintenance information of activated carbon, such as box size, processing air volume, replacement of activated carbon filling amount and its iodine value, as well as the operation and maintenance of the facility and the replacement of consumables, a waste gas treatment facility operation and maintenance ledger is established.

最后，企業(yè)要定期檢查活性炭的狀態(tài)。如果發(fā)現(xiàn)活性炭的孔隙堵塞、發(fā)白、破碎、潮濕等情況，應(yīng)立即更換廢舊活性炭。此外，廢舊活性炭屬于危險廢品，應(yīng)將其密封貯存，按照法律要求交由具備危廢處置資質(zhì)的企業(yè)處置。

Finally, enterprises should regularly check the status of activated carbon. If the pores of activated carbon are found to be blocked, white, broken, or damp, the waste activated carbon should be replaced immediately. In addition, waste activated carbon belongs to hazardous waste and should be sealed and stored, and disposed of by enterprises with hazardous waste disposal qualifications in accordance with legal requirements.

三、如何判斷活性炭是否失靈

3、 How to determine whether activated carbon is malfunctioning

觀察活性炭表面狀態(tài)，查看孔隙是否堵塞、活性炭表面是否發(fā)白發(fā)霉、吸水吸油、破碎解體等“非正常狀態(tài)”，出現(xiàn)以上現(xiàn)象，活性炭均屬于失活。

Observe the surface state of activated carbon, check whether the pores are blocked, whether the surface of activated carbon is white and moldy, absorbs water and oil, breaks and disintegrates, and other "abnormal states". If the above phenomena occur, activated carbon belongs to deactivation.
