The kiln bag filter is a dust removal equipment specially designed for high temperature and high concentration flue gas environment. It is widely used in tail gas treatment in industries such as cement rotary kiln, metallurgical roasting furnace, lime kiln, ceramic kiln, glass kiln, etc. Its core advantages are high efficiency dust removal, high temperature resistance, reasonable structure and strong adaptability. It is suitable for complex flue gas conditions that conventional electrostatic precipitators are difficult to handle.
★Product Features
1. High temperature corrosion resistant filter material design
PPS, FMS, PTFE and other high temperature resistant filter materials are selected, which are suitable for flue gas temperatures of 150℃~260℃ and can withstand temperatures of up to 300℃ for a short time.
The filter material has excellent acid and alkali resistance, anti-condensation, anti-oxidation and anti-sticking bag performance.
2. Separate chamber offline pulse cleaning
The separate chamber + offline pulse jet cleaning system is adopted, and each chamber is cleaned independently to avoid secondary dust flying, more thorough cleaning and longer filter bag life.
3. Strong sealing and air leakage prevention
The multi-stage sealing structure is adopted to ensure that the air leakage rate of the main body is less than 3%, preventing cold air from entering and causing condensation or filter bag damage.
4. Intelligent control system
Equipped with PLC automatic control system, it can monitor temperature, pressure difference, cleaning cycle, fan operation status in real time to achieve intelligent management.
5. Strong overall structure
Considering factors such as high-temperature thermal expansion and dust scouring, the shell adopts steel structure insulation design, which will not deform during long-term operation.
★Product advantages
1. Extremely high dust removal efficiency
The outlet dust emission concentration is conventionally controlled at <20mg/Nm³, and can reach <10mg/Nm³ after optimization, meeting the national ultra-low emission standards.
2. Adapt to various high-temperature flue gases
It can cope with kiln conditions with large fluctuations and frequent load changes, especially suitable for flue gases containing corrosive components such as SO₂, NOx, and alkaline gases.
3. Stable operation and low failure rate
The cleaning system is efficient, the filter bag performance is stable, the system has a small long-term pressure difference, low energy consumption, and strong continuous operation capability of the equipment.
4. Long filter bag life
Scientific filter bag selection, combined with offline dust cleaning control, can generally be used for 2 to 4 years, reducing maintenance and replacement costs.
5. Flexible and scalable system
Can be used in conjunction with desulfurization and denitrification equipment to achieve integrated ultra-low emission management.
