Abstract

The invention provides an automatic load regulating device and method used for a tube bundle type dust-removing mist eliminator, and belongs to the technical field of flue gas wet desulfurization, dust removing and demisting. The device and the method aim to solve the problem that when the dust-removing mist eliminator works under the low-load condition, the gas flow rate is low, the dust removal and demisting performance is declined, and fine dust and gypsum fog drops are difficult to remove. A liquid retaining ring is mounted on an outlet in the upper portion of a tube bundle type dust-removing mist eliminator cylinder body, the upper portion of the liquid retaining ring is sequentially provided with a flow guide ring and a floater support ring, the inner wall of the floater support ring is provided with a wedge-shaped gap, several fins are annularly distributed at the wedge-shaped gap of the floater support ring, a floater is in sliding connection with the fins, the outer wall of the floater is provided with sliding grooves matched with the fins, the lower end of the floater is matched with the wedge-shaped gap in the floater support ring, and a top plate is fixedly installed on the fins. The automatic load regulating device and method used for the tube bundle type dust-removing mist eliminator can automatically conduct load regulating of the dust-removing mist eliminator according to the change of gas flow rate of the tube bundle type dust-removing mist eliminator.

Description

technical field [0001] The invention relates to an automatic load adjustment device, in particular to an automatic load adjustment device and an adjustment method for a tube-bundle dust and mist remover, and belongs to the technical field of flue gas wet desulfurization, dust removal and fog removal. Background technique [0002] Limestone-gypsum wet desulfurization process is commonly used in the desulfurization process of coal-fired power plants in my country. This process will produce a certain amount of fine dust and "gypsum rain" during operation. Although the traditional dust removal and fog removal process can remove most of the pollutants, it cannot remove fine dust and gypsum droplets, and cannot alleviate the current situation of PM2.5 exceeding the standard. In addition, with the full implementation of new air pollutant emission standards for thermal power plants in my country and the promulgation of the "Coal Power Energy Conservation and Emission Reduction Upgra...
