To provide a particle separation apparatus, capable of increasing a recovering ratio of at least one of a particle of a positive charge and a particle of a negative charge from a mixture of the particle of the positive charge and the particle of the negative charge, and high separation efficiency of the particle of the positive charge and the particle of the negative charge, and to provide a particle separation system using it.
The particle separation apparatus has a positive electrode 32 for attracting an ash content (a particle of a negative charge), a negative electrode 33 which is arranged to be faced to the positive electrode 32 and attracts an unburned carbon (a particle of a positive charge), a discharging part 36 wherein a mixture of the ash content and the unburned carbon is discharged between the positive electrode 32 and the negative electrode 33 to form a flow of the mixture between the positive electrode 32 and the negative electrode 33, an ash recovering part 37 which is arranged at the side of the positive electrode 32 in the lower side of the flow of the mixture, and an unburned-carbon recovering part 38 which is arranged at the side of the negative electrode 33 in the lower side of the flow of the mixture. A discharging opening 36b of the discharging part 36 is arranged at any one electrode side of the positive electrode 32 and the negative electrode 33 in relation to a middle position of the positive electrode 32 and the negative electrode 33.
