PURE-AIR is a manufacturer of industrial production and processing smoke and dust collector for more than 10 years. It has a detailed understanding of the smoke and dust in the workshops of major production and processing enterprises, especially in the dust storage company that implements environmentally friendly dust collection equipment for efficient purification. Harsh dust in the workshop pollutes the environment.

1. Bag filter: The bag filter is mainly a bag filter. The bag filter has become the most widely used dust removal equipment, and the pulse bag filter has become the most important type of bag filter.

Advantages: The bag filter has high dust removal efficiency, can remove fine dust particles, has strong adaptability to changes in processing air volume, can capture a large range of dust particles, and is most suitable for processing small particles with recycling value. The structure is relatively simple. The operation is also relatively stable.

Disadvantages: The one-time investment cost of the bag filter is high, and the allowable temperature is low (high temperature and easy to burn). The temperature of the gas during operation must be higher than the dew point temperature. Otherwise, it will not only increase the resistance of the fume extractor, but also due to wet dust. Attached to the surface of the dust removal filter bag, so that the dust collector cannot work normally. When the dust particle concentration exceeds the lower limit of dust particle explosion, the bag filter cannot be used. In addition, the cloth bag is easy to be damaged, and the dust removal will cause the dust to fly up again.
2. Electrostatic precipitator: Electrostatic precipitator, referred to as "electrostatic precipitator", uses static electricity to attract light and small objects and uses static electricity to absorb industrial dust.

Advantages: Compared with other dust removal equipment, the electrostatic precipitator has a high degree of automation, less energy consumption, and high dust removal efficiency. It is suitable for removing the dust of 0.01~50μm in the flue gas, and can be used in the occasions of high flue gas temperature and pressure. Practice has shown that the greater the amount of flue gas processed, the more economical the investment and operating costs of using electrostatic precipitators.

Disadvantages: The equipment of the electrostatic precipitator has a large investment in one time, the equipment is complicated, and the area is large. It has strict requirements on operation, operation, and maintenance management. The vacuum cleaner will cause the dust to fly again. At the same time, there are also requirements for the resistance ratio of the dust. At present, electrostatic precipitators are mainly used in large enterprises that process large amounts of gas, have strict requirements on emission concentration, and have a certain level of maintenance and management, such as power plants, building materials, metallurgy and other industries.
