A device that is used for in tube cavity inner wall spraying tiO2 nanometer coating

The utility model discloses a device that is used for in tube cavity inner wall spraying tiO2 nanometer coating, including dielectric barrier discharge plasma generator, titanium source, motor, high voltage power supply, the medium of characterized by dielectric barrier discharge plasma generator is mouldable's cavity dielectric pipe to pipe diameter and crooked degree according to need coating film lumen design. But plasma generator dip nozzle intracavity portion excites the bramble form low temperature plasma who produces high electron density for the titanium source fully acts on and spraying in tube cavity inner wall with working gas, is had self -cleaning function's titanium dioxide nanometer coating. Use this device spraying tiO2 nanometer coating, overcome the traditional approach can only be in the basement of plane the shortcoming of coating film. In addition, the device can high -efficient coating film, easy operation, with low costs, and the ozone concentration is extremely low simultaneously, has
