High-altitude exhaust purifier is to discharge the purified flue gas to high altitude. It is necessary to install the exhaust pipe at the outlet of the exhaust purifier. High altitude exhaust purification rate is relatively low. Generally speaking, the purification efficiency of the high-altitude exhaust purifier can reach 60% - 70%, which is suitable for places with smoke ducts on roofs and no complaints from residents. Prices are also more affordable, reducing costs.

　　低空排放是指只有效率高的才能直接從窗外排放。低空排煙凈化器的凈化效率一般在95%以上。山東煙氣凈化低空排放適用于屋頂無煙道，對周圍環境更為敏感。此外，低空排煙凈化器可以將凈化后的氣體直接排放到大氣中，不需要在排煙口做排煙管。

　　Low-altitude emission means that only high efficiency can be directly discharged from the window. The purification efficiency of the low-altitude smoke exhaust purifier is generally over 95%. The low-altitude emission of flue gas purification in Shandong Province is suitable for roof flue-free, and more sensitive to the surrounding environment. In addition, the low-altitude exhaust purifier can discharge the purified gas directly into the atmosphere, and it does not need to make exhaust pipe at the exhaust port.

　　通過以上對比可以發現，低空排放凈化器比高空排放凈化器功能更大，能耗更高，效果更強，并且排煙凈化器的相差幾倍。但兩種尾氣凈化器設備均能滿足排放標準的要求。你可以根據餐廳的條件來選擇。檢查“產品中心”，并選擇正確的煙霧凈化器為您!

　　Through the above comparison, we can find that the low-altitude exhaust purifier has greater function, higher energy consumption and stronger effect than the high-altitude exhaust purifier, and the price of the exhaust purifier is several times different. However, the two kinds of tail gas purifier equipment can meet the requirements of national environmental protection emission standards. You can choose according to the conditions of the restaurant. Check the "product center" and select the correct smoke purifier for you!

　　山東地區排煙凈化設施大允許排煙濃度、氣味濃度、小去除率、排煙筒小排放高度。本標準適用于煙排放管理在城市組合地區現有的餐飲單位,自然保護區和旅游景點,以及設計、環境影響評價、環境保護和煙霧排放竣工驗收管理操作期間新建的擴大或重建餐飲單位;非營利性單位的食品加工單位和內部工作人員食堂排放煙霧的，適用本標準。
