摘要： A cylindrical chamber has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent thereof. This drive shaft is rotatably driven by a motor at a speed of 1,500-10,000 rpm. Solid particles to be comminuted which may be of coal, limestone/dolomite, cement or lime are fed into the chamber. Pressurized air is fed into the bottom of the chamber. Uplifting pressure for driving the gas and particles upwardly in the chamber may be provided by pressurized gas fed in through a tangential inlet in conjunction with a stationary velocity head. The upwardly driven particles are first driven through a plurality of short arm rotors which are driven by the shaft and provide a centrifugal force which comminutes the particles. The particles are then driven through a plurality of semi-permeable screens which are rotatably driven by the shaft and further comminute the particles. High apex flow enhancers are installed along the walls of the chamber to enhance the fluid flow. The fully comminuted particles are expelled from the top end of the chamber.

摘要： A cylindrical chamber has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent thereof. This drive shaft is rotatably driven by a motor preferably at a speed of about 3600 rpm. Solid particles to be comminuted which may be of coal, limestone/dolomite, or hydrated lime are fed into the chamber. Pressurized air is fed into the bottom of the chamber. Uplifting pressure for driving the air and particles upwardly in the chamber may be provided by pressurized gas in conjunction with a stationary velocity head. The upwardly driven particles are first driven through a plurality of rotors which are driven by the shaft and provide a centrifugal force which comminutes the particles. The particles are then driven through a plurality of semi-permeable screens which are rotatably driven by the shaft and further comminute the particles to a micronized state. To lower NO.sub.x and SO.sub.2 emissions when the micronized particles are combusted, the surfaces of the particles are modified by spraying with an aqueous atomized spray of an agent such as ethylene glycol or magnesium acetate which is injected into the chamber. Second chamber similar to the first. The reduction of acid gases and air toxics in the flue gases emitted from coal fired boilers is completed through duct injections of selected reagents.

摘要： Semi-permeable screens are installed in a pulverized coal burning boiler and rotatably driven by a high speed rotatable shaft. A first one of the screens is located above the main combustion zone of the boiler and a second one of the screens is located directly under the burnout zone of the boiler. The underside of the first rotating screen repels the larger and slower burning fuel particles that escape from the main combustion zone so that they are recycled for a complete burn-out. The smaller glowing particles suspended in the combustion gases pass through the first rotating screen and are micronized by the comminution effected by the spiral vortexes generated above this first screen. The second rotating screen positioned under the burnout zone provides for mixing and comminution of the gases and burning coal particles respectively. The vortexes generated by the screens homogenize the heat distribution in the upwardly moving stream of gas and solid particulates. The fuel may consist of micronized or pulverized particles or lumps of solids and may be combusted by itself or in admixture with sorbents for the flame scrubbing of SO.sub.x and NO.sub.x.

摘要： A liquid having certain undesired elements therein is distilled in a distillation column to form a vapor stream. This vapor stream is fed by means of an inert gas drive to a first container having an array of semi-permeable screens which are rotated at a speed of 3,000-10,000 rpm to generate vertical spiral vortexes which act on the vapor to separate out heavier impurities. An inert gas is employed to drive the vapor stream from the first container to the bottom of a second container having a narrower diameter array of semi-permeable screens, these screens being driven at a velocity of 6000-100,000 rpm. In the second container, the molecular species is separated from the main vapor stream by virtue of the exposure of the vapor to large centrifugal gravity forces generated by the horizontal velocity vectors of the rotating screens. The more volatile first fraction of vapor exits the column to a condenser where it is transformed to liquid form and provides the output of the system while the second less volatile fraction of the vapor is fed to the bottom of the array from where it is exited.

摘要： A single cylindrical chamber has a drive shaft rotatably mounted therein and extending along substantially the entire length thereof. This drive shaft is rotatably driven by a motor at a speed of 2000-5000 rpm, this speed being chosen so that the natural resonant frequency of the various components of the system is at least three times this rotation speed. Solid dry coarse particles to be comminuted which may be of coal, limestone/dolomite, cement or lime are fed into the chamber. Pressurized air is fed into the bottom of the chamber which in conjunction with a stationary velocity head provides uplifting pressure for driving the air and particles upwardly in the chamber. The upwardly driven particles are first driven through a plurality of rotors which are driven by the shaft and provide a centrifugal force which forms them into a vertical toroidal fluid bed that allows increased tonnage production and comminutes the particles. The particles are then driven through a plurality of semipermeable screens which are rotatably driven by the shaft and generate vertical vortexes and horizontal cyclones, thereby further comminuting the particles and providing for internal classification. The final product consisting of comminuted and classified particles is expelled from the top end of the chamber.

摘要： A chamber has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent of the chamber. This drive shaft is rotatably driven by a motor at a speed of 1,200-10,000 rpm. A plurality of screens having a mesh of 6-10 mesh are spaced from each other along the longitudinal extent of the chamber in opposing relationship and attached to the drive shaft for rotation therewith. Above the screens are a pair of discs which are attached to the shaft for rotation therewith and longitudinally spaced from each other. First and second similar plates having circular apertures formed therein are fixedly attached to the chamber in longitudinally spaced relationship, the first and second discs being positioned in the apertures of said first and second plates respectively. Gas to be purified is fed into the bottom of the chamber and driven upwardly by a compressor fan attached to the drive shaft. The gas first passes through the rotating screens which comminute and modify the surface characteristics of the microparticulates in the gas and then through circular vortex zones formed between the spinning discs and their opposing plates where the particles are sheared and separated from the gas by centrifugal expelling fans attached to the shaft. Purified gas is fed out from the top of the chamber for utilization in driving a gas turbine or other purpose.

This drive shaft is rotatably driven by a motor at a speed of 1,500-10,000. Solid particles to be comminuted which may be of coal and limestone/dolomite or lime are fed into the vessel. Connected to the shaft and rotatably driven therewith is a centrifugal compressor fan which forms an uplifting air curtain which suspends the particles. Mounted above the compressor and rotatably driven by the drive shaft are a plurality of rotors, screens, and a disc mounted in an aperture formed in a fixed plate which forms a circular vortex in the space between the disc and the plate. The particles are comminuted by the successive action of the rotors, screens and the circular vortex, larger particles being repelled for further comminution while the finer particles are fed from the vessel to cyclonic classifiers. The fully comminuted particles are removed for utilization while the gas which carried the particles is first cooled to liquidize moisture which is removed therefrom and then recycled to the vessel.

摘要： A cylindrical vessel has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent thereof. This drive shaft is rotatably driven by a motor at a speed of 3,000-10,000 rpm. The output of a roller mill or the like having particles of the order of -200 mesh to be further comminuted, which may be of coal or other minerals, are fed into the vessel. Connected to the shaft and rotatably driven therewith is a centrifugal compressor fan. This fan with additional air intake to the vessel provides a high velocity air curtain which suspends the particles and drives them upwardly. Mounted above the compressor and rotatably driven by the drive shaft are a plurality of semipermeable screens which comminute the particles to bring them to a superfine state. Particles which are not comminuted to a superfine state are repelled by the screens for further comminution. Fully comminuted particles are passed through an aperture in a fixed plate and fed to collecting cyclones which collect these particles.
