Embodiment 1
[0033] This embodiment is a Φ200mm, 20mm×60mm direct-cut tangential air inlet tangential reverse cyclone separator, a Φ150mm particle bed filter and a vortex fan controlled by a frequency converter. Such as figure 1 , the inlet of the frequency conversion fan is connected with the tangential outlet of the circulating airflow of the bottom ash hopper to carry out the pumping cycle, and the outlet of the frequency conversion fan is connected with the inlet of the dust-laden airflow. The test was carried out at room temperature, and the test device was operated with suction-type negative pressure. The gas is sucked in directly from the atmosphere, passed through a cyclone separator and a particle bed filter, and then evacuated by a fan. The swirling air velocity and filtering air velocity are measured by the Pitot tube on the pipeline. The dust concentration was measured at the outlet of the dust collector and the outlet of the bottom circulating airflow to calculate the total ...
