Abstract
A cyclonic processing system accepts unprocessed fragmentary material of a predetermined aerodynamic buoyancy range, keeps it suspended in a vortex and discharges it when it reaches a finished material aerodynamic buoyancy range. The cyclonic processing apparatus and method dries, mills, separates and/or mixes fragmentary material. The waste air from the apparatus is reduced in particle content. The apparatus and method may be used to process post consumer waste for recycling. Additionally, it may be used to harness waste heat from industrial processes.
Claims7
A method of processing fragmentary material to a first range of aerodynamic buoyancy, said method comprising:
- (a) providing a cyclonic processing apparatus, including a substantially vertical chamber having a top vent, an air inlet, a first unprocessed fragments inlet, a first processed fragments outlet, an air inlet heater and an air temperature measurement device;
- (b) introducing air into said air inlet and creating an upwardly spiraling vortex of said air within said chamber;
- (c) introducing said fragmentary material into said chamber through said unprocessed fragments inlet;
- (d) suspending said fragmentary material in said vortex and vertically stratifying said material upwardly according to decreasing aerodynamic buoyancy while radially stratifying said material outwardly so that air at the center of said vortex is more free of said material than air at the periphery of said vortex;
- (e) discharging said fragmentary material conforming to said first range of aerodynamic buoyancy from said chamber through said first processed fragments outlet;
- (f) discharging said air at the center of said vortex from said chamber through said top vent;
- and
- (g) controlling said air inlet heater in response to said air temperature measurement device.
A method of processing fragmentary material to a first range of aerodynamic buoyancy, said method comprising:
- (a) providing a cyclonic processing apparatus, including a substantially vertical chamber having a top vent, an air inlet, a first unprocessed fragments inlet and a first position adjustable processed fragments outlet;
- (b) positioning said first position adjustable processed fragments outlet to a position corresponding to said first range of aerodynamic buoyancy;
- (c) introducing air into said air inlet and creating an upwardly spiraling vortex of said air within said chamber;
- (d) introducing said fragmentary material into said chamber through said unprocessed fragments inlet;
- (e) suspending said fragmentary material in said vortex and vertically stratifying said material upwardly according to decreasing aerodynamic buoyancy while radially stratifying said material outwardly so that air at the center of said vortex is more free of said material than air at the periphery of said vortex;
- (f) discharging said fragmentary material conforming to said first range of aerodynamic buoyancy from said chamber through said first processed fragments outlet;
- and
- (g) discharging said air at the center of said vortex from said chamber through said top vent.
A method of processing fragmentary material to a first range of aerodynamic buoyancy, said method comprising:
- (a) providing a cyclonic processing apparatus, including a substantially vertical chamber having a top vent, an air inlet, a first unprocessed fragments inlet, a first processed fragments outlet and a spray inlet;
- (b) introducing air into said air inlet and creating an upwardly spiraling vortex of said air within said chamber;
- (c) introducing said fragmentary material into said chamber through said unprocessed fragments inlet;
- (d) suspending said fragmentary material in said vortex and vertically stratifying said material upwardly according to decreasing aerodynamic buoyancy while radially stratifying said material outwardly so that air at the center of said vortex is more free of said material than air at the periphery of said vortex;
- (e) discharging said fragmentary material conforming to said first range of aerodynamic buoyancy from said chamber through said first processed fragments outlet;
- (f) discharging said air at the center of said vortex from said chamber through said top vent;
- (g) spraying water through said spray inlet into said substantially vertical chamber.
