kiln dust collector

The kiln dust collector is developed based on the summary of the advantages and problems of various wet dust collectors for cement kilns. It is a dust collector that combines jet induction, cyclone dual water desert, and spray washing with dual pole dust removal and a new type of ash water separation technology. Dust recycling and utilization system. This equipment has been fully recognized and highly praised by multiple cement industry applications. The exhaust gases from the two chimneys of the mechanized shaft kiln enter the dust removal tower tangentially under jet induced acceleration, forming a cyclone. Due to the centrifugal force, most of the dust is captured by the inner and outer water films towards the wall of the separator, completing the first stage of division; As the airflow continues to rotate and rise, it undergoes spray washing to complete the second stage of dust removal.

The exhaust gases from the two chimneys of the mechanized shaft kiln enter the dust removal tower tangentially under jet induced acceleration, forming a cyclone. Due to the centrifugal force, most of the dust is captured by the inner and outer water films towards the wall of the separator, completing the first stage of division; As the airflow continues to rotate and rise, it undergoes spray washing to complete the second stage of dust removal. The removed grey water mixture flows into the grey water separator for separation treatment. The concentrated grey water is discharged from the lower part of the separator to the scraper conveyor, and then sent to the raw material for mixing into balls for recycling. The clarified water flows out from the upper part of the separator to the intermediate water tank, and then enters the dust removal tower through the water pump. It forms a water film through the circular arrangement of nozzles, achieving the recycling of water. All equipment is centralized in one electronic control console for safe operation, and the electronic control system adopts some necessary sound and light alarm devices.

The dust removal tower consists of an outer tower and a secondary tower, both made of stainless steel plates. The outer tower has a diameter of 2.4m and a height of 12.7m. The auxiliary tower has a diameter of 0.5m and is located in the center of the tower. Eight swirl nozzles are arranged in a circular pattern along the lower part of the outer tower for spraying and washing. The grey water separator is made of ordinary steel plate, with a "TO" resin anti-corrosion effective diameter of 2.8m on the inner wall and a total height of 4.3m. There is a mud collection device driven by a reducer in the center, and the mortar deposited on the plow on the mud collection arm is scraped towards the center and discharged. When the mud collection arm stops running due to a fault, it can also emit an audible and visual alarm. After treatment, it still cannot resume operation, and industrial cleaning is applied. The mud collection arm is stuck due to power outages or long-term failure to discharge mud. The longer the power outage, the more serious the fault. Therefore, users are required to be equipped with dual power supplies.
