Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model and operation principle are described in further detail.

First embodiment:

As Figure 1-3: a kind of tower-type solar thermal power generating system with electrodes for removing dust, comprise optically focused tower 1 and mirror field 2, described optically focused tower 1 is provided with heat dump 3, described mirror field 2 is arranged by multiaspect heliostat 5 and forms, multichannel sunshine gathers on described heat dump 3 by described multiaspect heliostat 5, generate electricity for generating equipment 4 after solar energy is converted to heat energy by this heat dump 3, the side to light of described heliostat 5 is distributed with N bar parallel pole, described N bar parallel pole is alternately connected with three phase mains successively, and N is the integral multiple of the power supply number of phases.
