Combined layout structure of flue gas system with six outlets of dust collector and double row induced draft fan

Abstract

The invention discloses a subsequent flue gas system combined arrangement structure for six outlets of a dust remover and induced draft fans in two rows. The structure comprises double rows of the induced draft fans connected with the six outlets of the dust remover, desulfurization absorption towers correspondingly connected with the double rows of induced draft fans, and chimneys connected with the desulfurization absorption towers, wherein the center lines of the double rows of induced draft fans, the desulfurization absorption towers and the chimneys connected in sequence are located on the same plane; the desulfurization absorption towers and the chimneys are vertically arranged side by side closely; the double rows of induced draft fans are transversely arranged at the outer sides of the desulfurization absorption towers side by side; the desulfurization absorption towers are arranged between the double rows of induced draft fans and the chimneys; and outlets of the double rows of induced draft fans are all aligned to the desulfurization absorption towers. All pieces of equipment behind the dust remover are arranged in a linear space in a combined manner, so that the equipment arrangement is more compact, the floor occupancy is reduced, and the flue connecting length is shortened.

Description

technical field [0001] The invention relates to the technical field of structural layout of a thermal power plant, in particular to a joint layout structure of a dust collector with six outlets and a flue gas system behind a double-row induced draft fan. Background technique [0002] In a coal-fired thermal power plant project, the distance from the outlet of the dust collector 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 boiler, and the layout of the front flue and the dust collector is relatively fixed. The size of the equipment layout behind the dust collector and the flue cost account for a large proportion of the initial investment of the power plant, and the resistance of the flue also directly affects the operating economy of the power plant. [0003] The main layout pattern of the equipment after the dust collector at home and abroad is basically to arrange th...

Problems solved by technology

[0005] Based on this, aiming at the unreasonable layout of the above-mentioned traditional equipment after the dust collector, it is difficult to make full use of the space everywhere, so that the layout of the equipment after the dust collector occupies a large area, the flue is long, and the resistance is large. The present invention proposes a dust removal Combined layout structure of the flue gas system behind the six outlets of the device and the double-row induced draft fan
