Combined layout structure of the rear flue air system with six outlets of dust collectors in power plants

Abstract

The invention relates to a rear air-flue gas system combined arrangement structure with six dust remover outlets for a power plant. The rear air-flue gas system combined arrangement structure comprises the six dust remover outlets, an induced draft fan structure, a desulfurization absorbing tower, a wet electrical dust remover structure and a chimney, wherein the induced draft fan structure is a double-column induced draft fan structure composed of two induced draft fans, every three dust remover outlets are connected with an air inlet of one induced draft fan, and air outlets of the two induced draft fans are connected with an air inlet of the desulfurization absorbing tower; the wet electrical dust remover structure is composed of four wet electrical dust removers; the desulfurization absorbing tower is provided with one air inlet and four air outlets; the induced draft fan structure and the six dust remover outlets are formed between the desulfurization absorbing tower and the chimney, the induced draft fan structure is located below the six dust remover outlets, the wet electrical dust remover structure is located above the six dust remover outlets and just over the induced draft fans, the six dust remover outlets are horizontally formed, the air inlets of the induced draft fan structure are vertically formed, and the air outlets of the induced draft fan structure are horizontally formed. The rear air-flue gas system combined arrangement structure disclosed by the invention is low in cost, occupies small space, and is good in running effect.

Description

technical field [0001] The invention relates to a joint layout structure of the rear flue air system with six outlets of a dust collector used in a power plant, and belongs to the technical field of power plant smoke exhaust and ventilation equipment. Background technique [0002] In a coal-fired thermal power plant project, the distance from the first column of the boiler to the center line of the chimney is one of the important land occupation indicators. Most of the equipment in the flue gas system is arranged behind the furnace, while the boiler room frame, front flue and dust collector The layout is relatively fixed, and the optimization of the layout after the furnace is mainly concentrated after the dust collector. For the layout form after the dust collector, the main layout pattern at home and abroad basically adopts the arrangement of each equipment in a row. The induced draft fan 1-2 is arranged after the dust collector 1-1, and the desulfurization absorption towe...
