The heat exchanger unit is then started for heat exchange. During this process, some impurities and scale will be generated in the return water after heat exchange. These impurities and scale tend to accumulate on the top of the unit, i.e., the cover plate. After heat exchange is complete, the heat exchanger unit must be shut down, the cover plate lifted off the rotating filter mechanism, and rotated to the side without the unit. The detachable filter mechanism is then manually disassembled for cleaning and replacement. Finally, the rotating filter mechanism is lifted off the top of the unit. Start by rotating the filter to the side without the main body, and use the flushing mechanism to spray water to rinse the rotating filter. After rinsing, turn off the flushing mechanism. Then, rotate the rotating filter and the cover plate back to the top of the main body and install them. Compared with existing technologies, by adding a detachable filter, some dirt and impurities can be avoided from accumulating on the inner top wall of the cover plate and being difficult to clean. Simply remove the detachable filter to remove the impurities and dirt attached to it. By rinsing the rotating filter with water, the dirt and impurities on the rotating filter are loosened and cleaned, which improves the normal heat conduction during the heat exchange process and reduces the accumulation of impurities and dirt on the top of the main body.
