The working principle of the rotary kiln dust collector: The dust generated by the rotary kiln dust collector production line is first fed into the ash hopper of the cooler under the action of the fan. Large particles of dust settle down under the action of gravity, and the concentration of smoke and dust is further reduced, thereby reducing the workload of the dust collector. The high-temperature gas enters the water-cooled radiator under negative pressure, and the water-cooled cooler adopts the water in the tube process. The high-temperature flue gas transfers heat to the water through the tube arm, and the water that absorbs heat flows out of the cooler and then cools down for recycling. The cooled gas continues to ascend into the dust collector, where fine dust is trapped on the surface of the filter bag. The clean gas penetrates the filter bag and is removed by the fan, achieving smoke and dust purification. As the dust on the surface of the filter bag thickens, the dust cleaning system is activated to sequentially remove the dust adhering to the surface of the filter bag, ensuring that the equipment always operates at low resistance. The fallen dust is shaken into the dust collector's ash hopper and discharged through the ash discharge valve for centralized treatment.

Performance characteristics of rotary kiln bag filter:

1. The rotary kiln dust collector adopts pulse jet cleaning technology, which has strong cleaning ability, high dust removal efficiency, low emission concentration, small air leakage coefficient, low energy consumption, low steel consumption, small footprint, stable and reliable operation, and good economic benefits. Suitable for flue gas treatment in industries such as power, building materials, metallurgy, and chemical engineering.

2. The box adopts an airtight design with good sealing performance. The inspection door is made of excellent sealing materials, and kerosene is used to detect leaks during the manufacturing process, resulting in a low air leakage rate.

3. Compact inlet and outlet air ducts, as well as air distribution devices, result in low airflow resistance.

4. The use of split chamber air stop pulse blowing for dust cleaning has a long cleaning cycle and low consumption, which can double the service life of filter bags and pulse valves.

5. It can achieve non-stop bag replacement and maintenance without affecting the normal operation of the equipment.

6. The use of upper bag extraction method has improved the operation of bag replacement.

7. A comprehensive control system ensures the long-term operation of the dust removal system.

Characteristics of flue gas from rotary kiln bag filter:

1. High dust concentration, with a dust concentration of 100-300g/m3 in the kiln tail exhaust gas;

2. High temperature: The temperature of the kiln tail exhaust gas after passing through the kiln tail preheater is around 350-400 ℃;

3. Dust particles are fine, with fine particles<10 μ m accounting for 90%;

4. Alkali content in dust;

5. The air volume is large and unstable as the kiln system conditions change.
