1、 Workflow

The BLS-8L wet shaft kiln dust collector consists of the main equipment dust removal tower, ash water separator, and auxiliary equipment such as water pump, fan, and electric control console. It is connected by pipelines to form a complete system for continuous dust removal, ash water separation, dust recovery and utilization, and water recycling.

2、 Operating mechanism

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 collector, completing the division process; As the airflow continues to rotate and rise, it undergoes spray washing to complete the stage 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 operation, and the electronic control system adopts some sound and light alarm devices.

3、 Main equipment structure and working principle

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 installed in the tower. Eight swirl nozzles are arranged in a circular shape along the lower part of the outer tower for spraying and washing. The grey water separator is made of ordinary steel plate, and the inner wall is made of "TO" resin anti-corrosion with a diameter of 2.8m and a total height of 4.3m. It is equipped with a mud collection device driven by a reducer, and the mortar deposited by the plow on the mud collection arm is scraped towards the center and discharged. When the mud collection arm stops running due to a malfunction, it can stop running and sound an audible and visual alarm. However, after processing, it still cannot resume operation, and industrial cleaning is applied. The jamming of the mud collection arm is caused by power outages or prolonged failure to discharge mud. The longer the power outage, the more severe the fault. Therefore, users are required to equip dual power sources.
