Circulating fluidized bed boiler cyclone separator composed of one-time bent pipe panel

Abstract

The invention relates to a circulating fluidized bed boiler cyclone separator composed of a one-time bent pipe panel. The outer side of the cyclone separator is composed of the pipe panel; the pipe panel is composed of a plurality of one-time bent pipes and flat steel arranged between every two adjacent one-time bent pipes; a heat insulating layer is arranged on the inner side of the pipe panel; a heat insulating and fire resistance layer is arranged on the inner side of the heat insulating layer; a second heat insulating layer is arranged on the inner side of the heat insulating and fire resistance layer; a wear-resisting layer is arranged on the inner side of the second heat insulating layer; a fire resistance brick layer is arranged on the inner side of the wear-resisting layer; and a fixed layer is arranged on the inner side of the fire resistance brick layer. Each single bent pipe formed by pairing of original three-section bent pipes is subjected to one-time bending, paired assembling and welding of the single pipes in the assembling process are reduced or cancelled, the manufacturing cost is reduced, the manufacturing cycle is shortened, the working efficiency is improved, and the product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of boiler production, and in particular relates to a cyclone separator for a disposable curved tube panel of a circulating fluidized bed boiler. Background technique [0002] The cylinder between the upper and lower headers of the current cyclone separator is assembled with a single elbow, and each single pipe is assembled with three sections of elbows. The workload is large and the quality cannot be guaranteed, and the weight of the current cyclone separator Large, thick, and long boot time. Contents of the invention [0003] In order to solve the above problems, the present invention provides a cyclone separator for a disposable elbow tube panel of a circulating fluidized bed boiler. Under the premise of meeting the technical requirements, reduce the butt welding of single tubes or cancel the butt welding of single tubes in the assembly process. [0004] In order to achieve the above object, the presen...
