Abstract

The invention discloses a dust removal device for a thermal power plant. The device is provided with an electrode plate dust removal portion and a corona pole dust removal portion, wherein the electrode plate dust removal portion is connected with a dust removal device base, the dust removal base is made to rotate by a motor, the electrode plate dust removal portion rotates around the central axis of the base to periodically and continuously clean dust adsorbed on an inner wall of a dust collecting electrode plate, and the corona pole dust removal portion is set on periphery of a corona pole and is driven to move up and down on an outer wall of the corona pole to remove dust particles adsorbed on a surface of the corona pole. Not only secondary dust is avoided, but also the electrode plate dust removal portion and the corona pole dust removal portion do not exert impact and vibration on the dust collecting electrode plate and the corona pole, service life of the dust collecting electrode plate and the corona pole is prolonged, a specific resistance detecting module is provided, the dust removal speed and duration of power supply interruption are controlled by detecting specific resistance of the dust particles, and thereby dust removal efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal in thermal power plants, in particular to a dust removal device for thermal power plants. Background technique [0002] Thermal power generation is a power generation method that uses the heat energy generated by combustibles during combustion and converts it into electrical energy through a power generation device. Due to China's abundant coal resources, thermal power generation is still an important way of generating electricity. A thermal power plant is a power facility that uses the thermal energy released by fossil fuel combustion to generate electricity, including all equipment, devices, and instrumentation devices for fuel combustion heat release, thermal energy conversion, and electrical energy output, as well as buildings and structures set up in specific places for this purpose And all ancillary facilities related to production and life. The fuel of thermal power plants i...
