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.
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.
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.
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. 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. 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. 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.
