product details

Introduction to FBPPF series explosion-proof gas box pulse bag filter technology
The FBPPF series explosion-proof gas box pulse bag filter adopts a new flame-retardant and explosion-proof structural design, and is equipped with complete safety monitoring and fire protection measures. Eliminating the hidden dangers of combustion and explosion inside the dust collector; In terms of cleaning high concentration coal powder, high-pressure pulse multi-point injection and microcomputer automatic control are used to ensure the long-term stable and efficient operation of the dust collector. Compared with similar products, the main features of this technology are: it can process coal dust with a dust concentration of up to 1000g/m ³ in one go: reducing process equipment, simplifying process flow, reducing system resistance, and reducing the installed capacity of fans; Reduced project costs, reduced operating expenses, and easier maintenance.

Working principle of FBPPF series explosion-proof gas box pulse bag filter
FBPPF series explosion-proof gas box pulse bag filter, when the equipment is running normally, the dusty flue gas enters the ash hopper through the air inlet; Part of the larger dust particles fall directly into the ash hopper due to inertial collision, natural settling, etc., while the rest of the dust particles rise with the airflow and enter various bag chambers. After filtering through the filter bag, the dust particles are trapped on the outside of the filter bag. The purified gas enters the box through the inside of the filter bag and is then discharged into the atmosphere through the lift valve and air outlet. As the filtration process continues, the dust accumulation on the outside of the filter bag increases, leading to a gradual increase in the resistance of the bag filter itself. When the resistance reaches the preset value, the dust cleaning controller sends a signal to first close the lift valve of a bag chamber to cut off the filtered airflow in that chamber. Then, the electromagnetic pulse valve is opened to quickly send the high-pressure reverse airflow used for dust cleaning into the filter bag. The filter bag rapidly swells and produces strong shaking, causing dust on the outside of the filter bag to fall off, achieving the purpose of dust cleaning. Due to the fact that the equipment is divided into several box areas, the above process is carried out box by box. While one box area is cleaning, the remaining box areas are still working normally, ensuring the continuous and normal operation of the equipment.
