Abstract:
1. A low-carbon, material consumption-free air cleaner, comprising: a rectangular box body, a dielectric barrier discharge actuator, a negative ion generator unit, a fan, an air input port and an air output port, said air input and output ports defining an air flow path therebetween; said fan, said negative ion generator unit and said dielectric barrier discharge actuator being disposed in the air flow path respectively arranged at upper part, middle part and lower part of said rectangular box body, said air input port being disposed at a bottom side of said dielectric barrier discharge actuator, said air output port being disposed at a top side of said rectangular box body wherein said fan creates a pressure drop within said rectangular box body, said fan mounted on an upper surface of said negative ion generator unit and sandwiched between said negative ion generator unit and said air output port; wherein said dielectric barrier discharge actuator includes positive and negative electrode plates disposed in opposing manner about said air flow path, each of said electrode plates having a catalytic coating formed on an insulative planar substrate and a plurality of mesh plates extending transversely across said air flow path, each of said mesh plates including a conductive structure having said catalytic coating; whereby said air flow path is unimpeded between said mesh plates and said fan; wherein said dielectric barrier discharge actuator comprises a dielectric catalyst structure, said positive electrode plate arranged at one side of said dielectric catalyst structure and said negative electrode plate arranged at an opposite side of said dielectric catalyst structure, said dielectric catalyst structure substantially defining a rectangular box having opposing top and bottom walls each formed by one of said mesh plates and four solid peripheral walls, said dielectric catalyst structure being made of said conductive structure having said catalytic coating, said coating selected from metal oxide or metal.
