Description

AN AERODYNAMIC DOSING APPARATUS
Field of the Invention Invention relates to dosing apparatuses, especially to aerodynamic dosing apparatuses for mixing fine particles, especially fine carbon particles with gas for creating gas-particles mixture.
Background of the Invention
Various dosing apparatuses exist which are configured to mix and/or dose the particles with air or any other gas.
State of art also discloses dosing apparatuses or mixers for preparation fuel or combustible mixture to a specification of certain burner or any other combustion-providing device. Dosing apparatus is a part of fuel burning systems, wherein particles, especially coal particles are mixed with an air before to be supplied to the burner or boiler. The aim of the dosing apparatus is to prepare the mixture of particles and air, wherein the particles are in uniform distribution and in a certain percentage to the air. As particle size is reduced up to 1 micron or less, the ordinary dosing apparatuses cannot provide necessary distribution of said particles in the air as well as maximum sputtering, separation of charcoal particles from each other in the air is reduced.

The aerodynamic dosing apparatus comprises three main elements: a hopper for feeding fine particles to be mixed with air, a tube attached to the hopper for feeding fine particles further for dosing and distribution to a third element, which is a dozer. The dozer is positioned at one end of the tube. Mixing and distribution of particles with air or any other gaseous environment is performed in said dozer.
The hopper may comprise additional means for transportation of the fine particles into the tube, for example screw conveyor. The hopper is preferably in the form of truncated cone, but it may be also in any other form, like cylinder, to facilitate feeding of fine particles into the tube.
The dozer comprises a dozer housing in the form of truncated cone with a narrow section in the lower part of the dozer housing and a wide section in the upper part of the dozer housing. Both sections of the truncated cone dozer hosing may comprise further cylindrical sections. The wide section of the dozer housing may be in the form of cylinder. The narrow section of the dozer housing may be in the form of cylinder.
The tube is inserted into the dozer through the wide section of the dozer housing and extends or protrudes into the dozer housing such that a circular gap is formed between an edge of the tube and an inner surface of the dozer housing. The circular gap may vary in a result of the movement of the tube relative to the inner surface of the dozer housing. The position of the circular gap in the dozer depends on an inclination angle of the conical dozer housing and diameter of the tube. The circular gap is adjustable by means of an actuator attached to the tube for providing movement of the tube into the dozer housing up or down relative to the inner surface of the dozer housing. The circular gap is enlarged by the movement of the tube out from the dozer housing or into the dozer housing and the circular gab is reduced by the movement of the tube into the dozer housing or out of the dozer housing.
Moreover, the gap divides the dozer in two chambers. The first chamber is formed in the area where the fine particles from the tube are introduced into the dozer and mixed with the air or any other gaseous environment coming from the gas inlet nozzle or nozzles. The second chamber is arranged upstream from the first chamber, wherein the mixture of air or any other gaseous environment and fine particles is fed from the first chamber through the circular gap and said mixture is ready to be fed out from the dozer through outlets. The aerodynamic dosing apparatus further comprises at least one gas inlet nozzle positioned in a narrow section of the dozer housing or in the first chamber of the dozer for feeding pressurized gas into the dozer housing. The gas inlet nozzle is positioned tangentially on a sidewall of the narrow section of the dozer housing. The gas inlet nozzle may be arranged at an angle relative to a central axis of the aerodynamic dosing apparatus.
The aerodynamic dosing apparatus further comprises at least one outlet positioned in a wide section of the dozer housing or in the second chamber of the dozer for outlet of a mixture of fine particles and gas out of the dozer.
The aerodynamic dosing apparatus further comprises one bellows arranged at the connection point between the hopper and the tube and another bellows arranged at the connection point between the tube and the dozer for providing hermetical and heat resistant healing. In result of which the dosing apparatus is able to receive gas or any other fluid in the range of about -190 to about 700 °C.
The aerodynamic dosing apparatus further comprises one circular insert arranged between the hopper and the tube at the connection point thereof and another circular insert arranged between the tube and the dozer at the connection point thereof for aligning of the hopper with the tube and the tube with the dozer. The circular inserts also provide additional sealing.
The tube and the dozer may be coaxially arranged on the central axis of the aerodynamic dosing apparatus. Moreover, the hopper, the tube and the dozer may be coaxially arranged on the central axis of the aerodynamic dosing apparatus.
The apparatus further comprises a detachable closure positioned at the narrow section of the dozer housing. The detachable closure may be in the form of threaded cap, which can be screwed or unscrewed depending on the necessity. The following closure provides easy cleaning and inspection of the hopper and the tube inserted into the hopper.
The designed dosing apparatus may be used not only for mixing and dosing of fine particles of coal but also any other type of fine particles like medicine particles. The dosing apparatus is able to receive almost any gaseous matter or gas including inert gases, steam and air. Gasses are fed under pressure to facilitate mixing of fine particles with said gas fed through gas inlet nozzle.
