Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention removes various kinds of dust, airborne bacteria, smoke, oil particles, and odor components in the atmosphere in buildings such as factories to clean the air and exhaust it outdoors. It is related to the exhaust structure of the building.

[0002]

2. Description of the Related Art Conventionally, shops such as restaurants, factories, workshops,
In buildings such as amusement facilities such as pachinko parlors, indoor air is polluted inside the building, so polluted air is exhausted to the outside with a ventilation fan, etc. However, filters and electrostatic precipitators were used as some of the things that have been done.

However, the filter has a limit against smoke, odor and fine particles and is particularly vulnerable to clogging by oil particles, and in an electrostatic precipitator, particularly odor, oil particles smaller than about 0.1 μm and dust are completely removed. It had the drawback that it could not be done.
