高空排放废气净化设备的净化效率可达60%-70%，而低空排放废气净化设备的净化效率可达95%以上。但两种尾气净化器设备均能满足排放标准的要求。
The purification efficiency of high-altitude exhaust gas purification equipment can reach 60%-70%, while that of low-altitude exhaust gas purification equipment can reach more than 95%. However, the two kinds of tail gas purifier equipment can meet the requirements of national environmental protection emission standards.
高空排气净化器的设备在排放前需要将净化后的气体送到高空，因此需要在排气净化器的出口安装排烟和排气管。该低空排烟净化器可将净化后的气体直接排放到大气中，因此无需在出口制造排烟管道。
The equipment of high altitude exhaust purifier needs to send the purified gas to high altitude before discharging, so it is necessary to install smoke exhaust and exhaust pipe at the outlet of the exhaust purifier. The low-altitude smoke exhaust purifier can directly discharge the purified gas into the atmosphere, so there is no need to manufacture smoke exhaust pipe at the exit.
山东烟气净化净化周期长，每次清洗维护时间快。不同类型的设备有不同的清洗周期和清洗方法。在正常情况下，正常的清洗保养并不会影响餐厅的正常运营，但是保养周期的长短以及每次保养的劳动强度和故障程度将是顾客选择净化器的重要标准。间隔1个月以上的清洗周期和每次不超过1小时的清洗维护时间是普通排烟净化设备的技术难点标准。然而，高性能的排烟净化设备基本可以清洗2个月以上，山东排烟净化一次仅需半小时左右。
Shandong flue gas purification and purification cycle is long, each cleaning and maintenance time is fast. Different types of equipment have different cleaning cycles and methods. Normally, the normal cleaning and maintenance will not affect the normal operation of the restaurant, but the length of the maintenance cycle and the labor intensity and failure degree of each maintenance will be the important criteria for customers to choose purifiers. Cleaning cycle with interval of more than one month and cleaning maintenance time of less than one hour at a time are the technical difficult standards of common smoke exhaust purification equipment. However, high-performance flue gas purification equipment can basically be cleaned for more than 2 months, and the flue gas purification in Shandong only takes about half an hour at a time.
山东烟气净化研究表达:烟气中含有多种对人体有害的化学成分，具有肺毒性、免疫毒性、遗传毒性、致癌性、诱变性等。
Research and expression of flue gas purification in Shandong Province: There are many harmful chemical components in flue gas, which are pulmonary toxicity, immunotoxicity, genetic toxicity, carcinogenicity, mutagenicity and so on.
1. 各风道连接处应采取防漏风措施，保证排烟净化器的输送。
1. The air leakage prevention measures should be taken at the connecting points of each air duct to ensure the conveyance of the smoke exhaust purifier.
2. 变直径风管与排烟净化器的进、出口相结合，应保证通顺，以保证安装的传动效果。
2. Combining the variable diameter air duct with the inlet and outlet of the smoke exhaust purifier, the fluidity should be ensured to ensure the transmission effect of the installation.
3.因此，在设置繁殖器风道时，必须采用软组合。整定操作时振动不正常。
3. Therefore, the soft combination must be adopted when the breeder duct is set up. Abnormal vibration during setting operation.
4. 为了保证感染的真实性，个人故意设置风机风量的虚假计划风量。3 .排烟净化器应在计划风量内，用户可使用变频器控制风机或在风机出口安装空气调节阀装置以完成。
4. In order to ensure the authenticity of the infection, the individual intentionally sets the false planned air volume of the fan. 3. Smoke exhaust purifier should be specially designed within the planned air volume. Users can use frequency converter to control the fan or install air-conditioning valve device at the outlet of the fan to complete.
