Description

Technical Field

[0001] The present invention relates to the technical field of dust collection of dust collectors, and in particular to a novel dust collection device for a flue of a dust collector and a method for improving dust collection capacity. Background Art

[0002] The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate smoke from the flue gas discharged by coal-fired boilers, thereby significantly reducing the amount of smoke discharged into the atmosphere. It is an important environmental protection equipment to improve environmental pollution and air quality. The electrostatic precipitator has significant advantages such as high purification efficiency, small equipment resistance, low total energy consumption, large flue gas treatment capacity, high allowable operating temperature, and can fully realize automatic operation control.

[0003] However, when the amount of ash at the inlet of the electrostatic precipitator flue is too large, it may cause the ash conveying system to be overloaded and the ash hopper level to rise, which in turn causes pipe blockage and poor ash conveying. The flow velocity distribution of the flue through the electrostatic precipitator is uneven. In places with low local wind force, the flue gas flow rate is high, and the residence time is therefore shortened, reducing efficiency. In addition, the air inlet angle is mostly fixed, making it impossible to adjust the airflow angle and control it. In addition, fly ash capture is very inconvenient and dust cannot be captured quickly. Summary of the invention

[0004] In view of the problems existing in the above-mentioned existing novel dust collector flue dust collection device and dust collection capacity improvement method, the present invention is proposed.
