The main reasons for the smoke from the exhaust outlet of the lampblack purifier are as follows:

原因一：油煙凈化電場極板上油污過多，在電場內部有雜物或電場變形，導致電場放電，此時油煙凈化器效果降低或者沒有的。

Cause 1: There is too much oil stain on the electrode plate of the lampblack purifying electric field, and there are sundries or electric field deformation in the electric field, leading to electric field discharge. At this time, the effect of the lampblack purifier is reduced or there is no lampblack purifier.

解決方案：取下電場以進行清洗，拆下電場去除雜質或恢復變形的電場。

Solution: Remove the electric field for cleaning, remove the electric field to remove impurities or restore the deformed electric field.

原因二：油煙凈化器匹配過大或者過小。設備風量匹配過大，廚房油煙通過設備的速度過快，在沒有處理的情況下就通過了凈化器，效果就會變差；設備風量過小，因廚房油煙量大，超過了設備的處理極限，會在排風口處出現白煙。

Reason 2: The matching of the lampblack purifier is too large or too small. If the air volume of the equipment matches too much and the kitchen lampblack passes through the equipment too fast, the effect will become worse if it passes through the purifier without treatment; The air volume of the equipment is too small. Due to the large amount of cooking fume in the kitchen, it exceeds the processing limit of the equipment, and white smoke will appear at the exhaust outlet.

解決方法：重配合適風量的油煙凈化器。

Solution: Refit the lampblack purifier with appropriate air volume.

原因三：風機功率不匹配。風機作為廚房油煙凈化器的輔助設備同樣具有十分重要的作用，風機功率過大會導致管道內風速過快，風扇功率過小則會導致管道風速過慢，這些都會起到凈化的反作用。

Cause 3: The fan power does not match. As the auxiliary equipment of kitchen lampblack purifier, the fan also plays a very important role. Too much fan power will lead to too fast wind speed in the pipeline, and too little fan power will lead to too slow wind speed in the pipeline, which will play a negative role in purification.

解決方法：重配一臺適當功率的風機。

Solution: Reassign a fan with appropriate power.

原因四：管道里有雜物；若管道內有雜物，如安裝管道時不慎在內部的雜物等，將增加管道阻力，影響管道風速，從而降低凈化效率。

Cause 4: There are sundries in the pipeline; If there are sundries in the pipeline, such as the sundries left in the pipeline inadvertently when installing the pipeline, the pipeline resistance will be increased, the pipeline wind speed will be affected, and the purification efficiency will be reduced.

解決方法：及時將管道內雜物進行清潔，保持管道整潔。

Solution: Clean the sundries in the pipeline in time to keep the pipeline clean.

原因五：在不合理的安裝情況下，它會導致排氣中的白色煙霧。安裝不合理、進出風口沒有安裝均風網、管道間隔短彎頭多、變徑口不合理等原因，都會造成排煙口出煙。

Cause 5: Under unreasonable installation, it will cause white smoke in the exhaust. Unreasonable installation, no air equalizing net installed at the air inlet and outlet, short pipe interval and many elbows, unreasonable reducer and other reasons will cause smoke from the smoke exhaust outlet.

解決方案：按照正確的事宜將安裝工作一一完成并檢查，防止因安裝問題而導致的凈化效率低的問題。

Solution: Complete and check the installation work one by one according to the correct matters to prevent the problem of low purification efficiency caused by installation problems.
