The invention provides a cylindrical
cyclone separation device and a special
cyclone guide ring for the same, and belongs to an energy-saving emission-reducing device. The cylindrical
cyclone separation device and the special cyclone guide ring for the cylindrical cyclone separation device mainly solve the technical problems that an existing fuel engine is not high in use efficiency and more in exhausted
waste gas, pollutes environment and the like. According to the technical scheme, the cylindrical cyclone separation device is characterized in that the two ends of a cylinder body (2) are sealed, the cyclone guide ring (5) is arranged on the lower middle portion of the cylinder body (2), the position, located on the upper portion of the cyclone guide ring (5), of the cylinder body (2) is provided with an air suction through hole, an air inlet
pipe (1) is installed in the air suction through hole, a lower partition plate (13) is arranged at the position, located on the upper portion of the air inlet
pipe (1), in the cylinder body (2), a
filter element (3) is arranged on the upper portion of the lower partition plate (13), the lower partition plate (13) is communicated with a cyclone cavity, an upper partition plate (4) is arranged at the upper end of the
filter element (3), the upper partition plate (4) is communicated with the filter cavity, and the outer wall of the upper portion of the cylinder body (2) is provided with an exhaust through hole, and an air outlet
pipe connector (9) is installed in the exhaust through hole in a matched mode. The cylindrical cyclone separation device and the special cyclone guide ring are mainly used for
energy conservation and emission reduction of fuel engines.
