Introduction
The air quality in urban environment especially in large cities has deteriorated significantly due to the increasing pollution, and particulate matter (PM) is the major component of this problem. PM, known as particulate matter, is a form of air pollution consisting of small particles and liquid droplets in the atmosphere, which comes from combustion and industrial processes. Particulate matter can cause serious health problems such as asthma and other respiratory diseases, cardiovascular diseases and cancer. In this case, effective abatement of particulate matter is of great significance for the protection of humans health and environment.
Generally, traditional technologies for particulate matter abatement include esp (electrostatic precipitator) and mds (multi-stage dust settling), which are suitable for applications where large particles size is present. But these technologies cannot effectively remove submicron sizes particle, which is more hazardous than the large ones. Therefore, an effective and efficient new technology for abatement of particulate matter is needed. In this paper, we are going to discuss one of the new technology, i.e. PPS (Particulate-trap Pre-separator) which utilize the combination of a pre-separator and a filter to capture particulate matters at submicron levels and employ a powerful suction component to transport the collected particulate matter.
Basics of PPS Technology
PPS, Particulate-trap Pre-separator, is a new particle abatement solution developed by American based company AFS. It is based on the combination of filter and pre-separator to capture particles from submicron sizes up to a diameter of 10 µm. The filter, which is developed using a special nanofibrous technology, is designed to trap the submicron size particles effectively, while the pre-separator, which is equipped with a rotating disc and blades, is used to separate the remaining large particles.
The PPS system is also equipped with a powerful suction component. This component is used to transport the collected particles to a storage unit or container, and to produce the same air pressure across the whole system, which ensures efficient and optimal operation of PPS system.
Advantages of PPS Technology
The PPS system has many advantages compared to other traditional air pollution abatement solutions. First, this system can effectively collect particles from the submicron level up to 10 µm, which makes it more efficient than ESP ad MD for abatement of particulate matter. Secondly, the use of a powerful suction component ensures optimal operation of the whole system, which makes it very reliable. Thirdly, the system requires low maintenance and operational cost compared to other traditional solutions, making it very cost-effective. Fourthly, PPS system does not use chemicals for its abatement process and does not generate by-products, which makes it more environment friendly. Lastly, the PPS system is very simple in design and easy to install and operate.
Applications of PPS Technology
The PPS system has been widely applied in a wide range of outdoor and indoor air pollution control applications. It is widely used in industrial air pollution abatement applications in areas such as power plants, chemical plants, factories and workshops. It is also used in air pollution abatement in municipal air pollution control applications. It is applied in indoor applications such as ventilation systems, exhaust systems and HVAC systems. It is also used in portable air pollution abatement systems, such as those used in mobile construction equipment.
Conclusion
PPS is an effective, efficient and cost-effective particulate matter abatement solution. It is based on the combination of filter and pre-separator to capture particles from the submicron sizes up to a diameter of 10 µm. This system is equipped with a powerful suction component which ensures optimal operation of the whole system. Because of its advantages, it has been widely applied in many air pollution abatement applications.
