Patent ID: 8652243

Claim:
A gas filtration apparatus, comprising: a gas suction unit configured to transmit a first gas flow which includes a polluted gas and external air to a first pipeline; the first pipeline configured to divide the first gas flow into a second gas flow and a third gas flow, and transmit the second and third gas flow to a second pipeline bundle, the second pipeline bundle configured to divide each of the second and third gas flow into two or more gas flows, and transmit each of the divided two or more gas flows to each of a plurality of filters; a purifying tank configured to contain first water for purifying a gas released from a plurality of filters; the plurality of filters positioned in the purifying tank to be sunk under the first water, and configured to disintegrate one or more bubbles created by the divided two or more gas flows from the second gas flow and the third gas flow; and a gas outlet configured to collect a plurality of bubbles emitted from the first water, and release the collected bubbles as a filtered gas flow to the outside of the gas filtration apparatus, wherein the each of the plurality of the filters comprises: a filter case configured to receive and trap one gas flow among the divided gas flows transmitted from the second pipeline bundle; a filter fan positioned in the inside of the filter case, and configured to be rotated to disintegrate the one or more bubbles created by the trapped one gas flow; a fan motor configured to generate a power to rotate the filter fan; and a fan shaft configured to transmit the power from the fan motor to the filter fan.
