Electrostatic separator | Russian patents
Usage: elektroseparatsiya bulk materials, the separation of fine-grained powders in size and composition. The inventive electrostatic precipitator is composed of a sealed housing, an electric field sources, devices for feeding the starting material and product separation discharge. In the sealed housing creative lighting is rotatable truncated cone with an inner surface coated with an electret. The bottom of the truncated cone serves as a centrifugal creative lighting feeder. From the external environment workspace separator isolated and placed in elegas. Message to the environment through special gateways. Separation of the material takes place on a rotating conical surface coated electret grains by interaction with the material being separated electret field. For fine-grained materials trajectory of the grains depend mainly on the mirror axis, and for pre-charged grains - from the Coulomb force. 3 SP f-ly, 3 ill.
Known separator [1], wherein the grain different permittivity belt sides extend to electrets. To remove the grain belt electrets detainees subjected to special cleaning or complete replacement, which is a disadvantage, since the process is interrupted for cleaning electrets.
Known electrostatic separator [2] for the separation of granular bulk materials. It is a division of the starting material depending on the forces of interaction with the electrostatic field grains formed by the cylindrical surface of the electret electrode and the metal resist.
A disadvantage of this separator is that the feeding of fine-grained powder on the surface of the electret drum rotating at high speed, the grain from the drum to bounce upon touching creative lighting by mechanical forces. The forces of interaction with the field of the electret grains creative lighting in such a situation is much less mechanical strength and separation process is absent. If the drum to rotate slowly creative lighting at a rate such that the powder was fixed on the surface of the electret, the grains are not torn by the centrifugal forces and the separation process is also absent.
The separator consists of a sealed housing 1 in which is rotatably disposed and a large base of the truncated cone-up 2, the inner lateral surface of which is formed as an electret three performed with the charge distribution along the generator in accordance with a mathematical expression r = Ao where r - the charge density corresponding to a radius r, C / m 2; a - charge density at the inlet of a truncated cone, C / m 2;
A - the coefficient equal to 1-1.2, cone drive motor 4 via the input shaft is sealed in the motor housing creative lighting of the separator, the angle between the generatrix of the truncated cone and a plane perpendicular to the axis of rotation is determined by mathematical expressions ck where ck - slip angle grains at the surface of the electret, a centrifugal feeder configured as a truncated conical bottom 2. The separator is provided with inlet and outlet creative lighting sluices 5-8 to feed the starting material and product collection separation.
Gateway scheme shown in FIG. 2 and 3, wherein the input comprises a gateway enclosure creative lighting 1 which is set up larger creative lighting base and rotatably vodka conical bottom 2 and the annular toothing 3, and communicated with a nozzle body for feeding particulate material 5, 6 and 7 of the air, Nitrogen 8, 9, 16 and 17 sulfur hexafluoride 10, 11, 18 and 19, the output of air supply pipes 12, 13 and 14 nitrogen material creative lighting 15. Filling pipe 5 is located in the inlet zone gateway air nozzles 6 and 7, and a discharge pipe 15 is formed as a cylindrical trough passes into the outlet on the bottom of the gateway so that communicates with insulating gas: same output gateways performed except that the inlet zone is located in the gas-and unloading - in air. 4 drive bevel lock plates 2 formed as a belt or gear located airside kinematically connected to the hub and mounted in bearings connected to the conical annular bottom plate.
Separated source material is fed through the gateway 5 (FIG. 1) in the bottom of the gas-filled separator rotating truncated creative lighting cone. Due to centrifugal creative lighting forces and the interaction with the surface of the electret grains trajectory of the different properties of different grains. Grain enters separator without precharge separation occurs due to the interaction of the induced charges and the electret beans by electrostatic induction. In the separation of grains from the surface of the electret creative lighting during movement on its surface corona discharge occurs between the grain and the surface of the electret. In gas-medium corona creative lighting discharge occurs at high breakdown voltage compared to air. The separator can also work with a pre-charged grains. The separation of the material takes place in a few fractions, which are collected in the respective collections and come through the weekend gateways 6-8 9-1 in the handling capacity
