高空排烟净化器是将净化后的烟气排放到高空。有必要在排烟净化器的出口安装排烟管。高空排气净化率相对较低。一般情况下，高空排气净化器的净化效率可达到60%-70%，适用于屋顶有烟道且居民无投诉的场所。也更实惠，可以降低成本。
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从窗外排放。低空排烟净化器的净化效率一般在95%以上。山东烟气净化低空排放适用于屋顶无烟道，对周围环境更为敏感。此外，低空排烟净化器可以将净化后的气体直接排放到大气中，不需要在排烟口做排烟管。
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.
通过以上对比可以发现，低空排放净化器比高空排放净化器功能更大，能耗更高，效果更强，并且排烟净化器的相差几倍。但两种尾气净化器设备均能满足排放标准的要求。你可以根据餐厅的条件来选择。检查“产品中心”，并选择正确的烟雾净化器为您!
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!
