AI Technical Summary
The lack of a stirring mechanism for alkaline liquid in existing medium-frequency electric furnace smoke removal devices results in a slow reaction rate, low absorption efficiency of the solution for smoke and dust, and flue gas easily leaving the alkaline solution before fully reacting. Furthermore, the high pressure of the graphite plate filter necessitates frequent replacement.
A medium-frequency electric furnace smoke removal device was designed, comprising a shell, an exhaust mechanism, a transmission mechanism, and a stirring mechanism. The exhaust gas is introduced into an alkaline solution by a blower and dispersed by a porous pipe. The gas is then filtered by an activated carbon filter plate and a filter cotton layer. The transmission mechanism drives a stirring rod to stir the alkaline solution, thereby accelerating the reaction rate and improving the capture efficiency.
It improves the reaction rate between alkaline solution and waste gas and the particulate matter capture efficiency, enhances the purification effect, reduces the exhaust pressure of the exhaust fan, and extends the service life of the graphite plate.
