Air Filtering Equipment For Air Condition Room In Subway Station

摘要

PURPOSE: An air filtering apparatus for the air conditioning room of a subway station is provided to easily filter fine dust and to maintain the efficiency of air purification for a long period of time using an electrostatic filter. CONSTITUTION: A filtering main body(100) includes an inlet(110) and an outlet(120) for air. A panel filter(140) is installed between the inlet and the outlet. An electrostatic filter(150) is installed between the inlet and the outlet. The inlet includes a first inlet(111) and a second inlet(112). External air is introduced through the first inlet. The second inlet circulates internal sir in a subway station. The electrostatic filter is a roll-type thin electrostatic filter or a fiber bundle filter. A plurality of pressure sensors(171, 172, 173) is arranged in the filtering main body. Dust sensors(175, 176) are arranged at the inlet and the outlet of the filtering main body.
