Abstract
A device for reducing wear to the inner wall of a cyclone separator by causing a protective layer of particulate to accumulate along the inner wall. The protective layer is facilitated by securing an expanded metal sheet along the inner wall of a cyclone separator. Once formed the protective layer of particulate acts as a shield and cushion to high-energy kinetic particles as they continue to enter the cyclone separator. The high-energy particles strike the accumulated particulate without harming the inner wall of the cyclone separator.
Claims10
An apparatus for protecting an inner wall of a cyclone separator which comprises:
- (a) an expanded metal sheet generally formed to the contour of the inner wall of the cyclone separator and having openings of between 0.25 inches and 1.6 inches;
- and
- (b) a means of securing said expanded metal sheet to the inner wall of the cyclone separator at a distance of between about 0.25 inches and 1.25 inches;
- (c) wherein particulate matter passes through the openings in the metal sheet and form a protective layer of particulate between the expanded metal sheet and the inner wall.
A method of providing protection to an inner wall of a cyclone separator comprising;
- a. securing expanded metal along an inner wall of a cyclone separator, wherein the expanded metal has openings of between 0.25 inches and 1.6 inches;
- b. spacing said expanded metal at a distance of between about 0.25 inches and 1.25 inches from the inner wall;
- and
- c. wherein particulate matter passes through the openings in the expanded metal and form a protective layer of particulate between the expanded metal and the inner wall.
