Cyclone dust removal device for high-temperature high-concentration gas

The utility model discloses a cyclone dust removal device for high-temperature high-concentration gas, which comprises a housing, wherein a material inlet is arranged at the middle part of the housing; a clean air outlet is arranged at the upper part of the housing; a material outlet is arranged at the lower part of the housing; a filtering area which is located between the material inlet and the material outlet is arranged in the housing; and the filtering area comprises at least two metal micro membrane filter elements. By improving the traditional air cyclone dust removal device and arranging the metal micro membrane filter elements in the cyclone dust removal device, the utility model greatly increases the pertinence and efficiency of gas and solid separation, lowers the dust content of clean gas below 50mg/nm 3, and can be applied to a high-temperature system over 300 DEG C; in addition, the device can effectively separate most solid particles of larger size through centrifugal separation before filterin
