[0025] refer to figure 1 , The sludge treatment facility 1 according to the first embodiment of the present invention is provided with: a fluidized bed incinerator 10; The fluidized bed incinerator 10 incinerates sludge such as dirty water sludge, excrement treatment sludge, and various waste water treatment sludge. Hereinafter, the case where the fluidized bed incinerator 10 is a bubble type will be described, but the fluidized bed incinerator 10 may be a circulation type. The diffuser 20 includes an air supply device 21 such as a blower, an air preheater 22 , a header 23 , and a plurality of diffuser pipes 30 . The air supply device 21 is connected to a header 23 via an air preheater 22 . The header pipe 23 is connected to a plurality of diffuser pipes 30, respectively. Each air-diffusing pipe 30 is formed in a straight pipe shape, inserted into the fluidized-bed incinerator 10 so that the axis of the air-diffusing pipe 30 becomes horizontal, and supported by the fluidize...

[0038] refer to Figure 4 , the diffuser tube 30A of the second embodiment of the present invention will be described. 30 A of diffuser tubes of this embodiment are comprised similarly to 30 A of diffuser tubes of 1st Embodiment except the following points. In this embodiment, the outer diameter D of the front end portion 31 31 than the outer diameter D of the root 32 32 Small and the inner diameter d of the front end portion 31 31 with the inner diameter d of the root 32 32 equal. In this embodiment, other diffuser tubes 30 including the diffuser tube 30B may be configured similarly to the diffuser tube 30A of the present embodiment, or may be configured similarly to the diffuser tube 30A of the first embodiment.

[0039] It should be noted that the outer diameter D of the front end portion 31 may also be 31 than the outer diameter D of the root 32 32 small and make the inner diameter d of the front end part 31 31 than the inner diameter d of the root 32 32 Big. In ...

no. 3 approach ）

[0041] refer to Figure 5 , the support structure 40 of the third embodiment of the present invention will be described. The support structure 40 of this embodiment is the same as the support structure 40 of 1st Embodiment except the following point. The support structure 40 of the present embodiment includes a support plate 47 instead of the support plates 42A and 42B. The support structure 40 of this embodiment is equipped with the support rib 48 arrange|positioned between adjacent sleeves. Support ribs 48 are welded to adjacent sleeves, curved plate 41 , and support plate 47 .

[0042] Such as Figure 6 As shown, through-holes 47 a and 47 b are formed in the support plate 47 . Bolt holes (not shown) are formed around the respective through holes 47 a and 47 b.

[0043] The support plate 47 is welded to the sleeves 44A and 44B so that the through hole 47a communicates with the inside of the sleeve 44A and the through hole 47b communicates with the inside of the sleeve 4...

Abstract

A diffusion tube for a sludge fluidized bed incinerator is provided with: a tip in which an exhaust nozzle that blows out air inside the fluidized bed incinerator is formed; and a base supported by the fluidized bed incinerator. The tip is thinner than the base.

Description

technical field [0001] The invention relates to an air diffuser pipe and an air diffuser of a sludge fluidized bed incinerator. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2009-222372 discloses a conventional dispersion tube support structure for a fluid incinerator. In this distribution pipe support structure, a channel bent downward is connected to the furnace outer base of the distribution tube inserted into the lower part of the furnace body of the flow incinerator in the horizontal direction, and the lower end surface of the channel is passed through a metal that can slide in the horizontal plane. The gasket is connected to the upper surface of the header for flowing air, and the lower surface of the header is elastically supported by a spring hook capable of displacing in the vertical direction. [0003] According to the discussion of the present inventors, as the scale of the fluidized bed incinerator increases, the length of ...
