Technical field
CFB boiler is the utility model is related to, it is particularly a kind of to prevent deflector top from accumulating water-cooling wall attachment ash
Water conservancy diversion alloy sheets.
Background technology
CFB boiler combustion technology is due to coal adaptability is wide, flameholding, pollutant discharge amount are few and easily controllable
And lime-ash the advantages that can comprehensively utilizing, turn into the low-grade burning highly effective cleaning burning for realizing commercialization and maximization at present
Utilization technology.
Though CFB boiler, which compares other type of furnaces, as above advantage, it is there is also some inadequate natural endowments, and stove internal heating surface is in gas
Worn Gu two-phase flow effect is lower, the transition region waterwall tube cracking problem being particularly between emulsion zone and dilute-phase zone, serious shadow
Ring the reliability of boiler operatiopn.Central gas stream moves upwards in CFB boiler burner hearth, and surrounding sticking wall flow flows downward, in sticking wall flow
Contained solid particle, after the beginning that flows downward, by Action of Gravity Field, flow velocity is cumulative, and water-cooling wall is caused to wear.It can be seen that water-cooling wall
Abrasion is due in stove caused by gas-solid bidirectional flow operation mechanism.
The existing device for being used for preventing sticking wall flow from wearing boiler water wall is the deflector laterally set, and it is in a side
Multiple arcs inner groovy is provided with, arc concave shape groove is stuck on water screen tube when in use, controlled with this in burner hearth
Adherent gas-solid flow velocity, reduces the abrasion of burner hearth.But added with deflector after, although gas-solid flow velocity is reduced, due to burner hearth
Interior environmental problem, the coal for some without burning are accumulated on the water screen tube on deflector, and in boiler operatiopn
During also have a part of particle and drop to transverse slat surface, falling on after transverse slat surface impact surface and four can then dissipate, will
Some is stacked on the membrane wall pipe above deflector, has had a strong impact on the heat conductivility of membrane wall pipe, and due to leading
The effect of flowing plate, certain vortex can be formed above deflector, easily cause the beveling to membrane wall pipe, accelerate membrane wall
The abrasion of pipe.
The content of the invention
For the above situation, to overcome the defect of prior art, the utility model provides a kind of water conservancy diversion and golden plate, effectively
Solve on the existing deflector laterally set has a large amount of dust stratifications along water screen tube, influences water screen tube thermal conductivity, and lead
The vortex formed above flowing plate wears the problem of aggravating to membrane wall pipe.
The utility model includes alloy sheets body, and alloy sheets body is provided with least one and membrane type towards the side of membrane wall
The corresponding inner groovy of wall pipe external diameter, the inner headed face for facing membrane wall of the inner groovy are provided with guiding gutter.
The utility model utilizes the guiding gutter set on inner groovy, eliminates the dust stratification on membrane wall pipe, enhances it
Heat conductivility, while hinder the formation being vortexed on deflector, reduce because vortex and to the abrasion of membrane wall pipe.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment 1.
Fig. 2 is the front view of the utility model embodiment 2.
Fig. 3 is front view when two alloy deflectors mutually overlap in the utility model embodiment 2.
Embodiment
It is described in further detail below in conjunction with 1 to 3 pair of specific embodiment of the present utility model of accompanying drawing.
Embodiment 1, the utility model include alloy sheets body 1, and alloy sheets body 1 is provided with least towards the side of membrane wall
One inner groovy 2 corresponding with membrane wall pipe external diameter, the inner headed face for facing membrane wall of the inner groovy 2 are provided with guiding gutter
3。
The guiding gutter 3 is deep-slotted chip breaker.
The guiding gutter 3 has three, uniformly at intervals on the inner headed face of inner groovy 2, wherein middle guiding gutter 3 is placed in indent
The middle of groove 2.Needed to be stuck on membrane wall pipe due to inner groovy 2 and fitted with the periphery of membrane wall pipe, therefore indent
Groove is the groove of arc, and middle guiding gutter is just placed in the inner groovy of arc along the interposition perpendicular to the direction of membrane wall pipe
Put.
Embodiment 2, on the basis of embodiment 1, a side of the alloy sheets body 1 and face membrane wall base it
Between be in indent the first arc transition 4, in the of indent between another side of alloy sheets body 1 and the base for facing membrane wall
Two arc transitions 5, the first arc transition 4 and the second mutually overlap joint of arc transition 5 form inner groovy 2.First arc transition and
Two arc transitions mutually overlap composition inner groovy, refer to during overlap joint between two adjacent alloy deflectors the first arc transition and
Second arc transition mutually overlaps.It is again provided with least on the inner groovy 2 that first arc transition 4 and the second arc transition 5 are formed
One guiding gutter 3, preferable guiding gutter 3 have three, and the guiding gutter 3 of three centres can be located at the middle of this inner groovy 2, tool
Body can be respectively equipped with notch 301 in the outer side edges of the first arc transition 4 and the second arc transition 5, in the first arc transition 4
Guiding gutter 3 is formed with two notches 301 during the second arc transition 5 mutually overlap joint.For example, when provided with three inner groovies 2,
And three guiding gutters 3 are respectively provided with three inner groovies 2, every three guiding gutters 3 have one among inner groovy 2, by both sides
Guiding gutter 3 be equal to towards outwardly direction or cross inner groovy 2 medium line cut can structure the present embodiment water conservancy diversion alloy sheets.
When being cut at medium line, the first arc transition and the second arc transition dock to form inner groovy 2, at outwardly over medium line
During incision, two arc-shaped transitions, which mutually overlap, forms inner groovy 2.Cut-off lines shown in Fig. 2 cross the medium line 6 of guiding gutter 3.
The utility model water conservancy diversion alloy sheets, when in use, its inner groovy 2 is stuck on membrane wall pipe, with membrane type
Wall pipe is brought into close contact, and water conservancy diversion alloy sheets are fixed on membrane wall, and the utility model sets guiding gutter 3, its inner opening of guiding gutter 3
Towards membrane wall pipe, traditional deflector upper end can adhere to dust stratification along membrane wall pipe, and due to being had upwards in air deflector
It is distinguished and admirable, and material flow moves downward, therefore after setting guiding gutter 3, distinguished and admirable to lead to from bottom to top out of guiding gutter 3
Cross, reduce the flow velocity that material flow is passed through out of guiding gutter 3, in addition it is upward distinguished and admirable due to having in guiding gutter 3, and material flow is blown
From, prevent its from out of guiding gutter 3 by, and it is distinguished and admirable the dust stratification of attachment membrane wall pipe can be dispelled along guiding gutter 3, avoid
Adhere to dust stratification on membrane wall pipe and the problem of influence thermal conductivity, because this opening surface of guiding gutter 3 is towards membrane wall pipe, advantageously in
The dust stratification being attached on membrane wall pipe is directly blown off from guiding gutter 3 along membrane wall pipe, and by distinguished and admirable in guiding gutter 3,
Greatly reduce on deflector vortex formed and to the abrasion of membrane wall pipe.
The utility model utilizes the guiding gutter set on inner groovy, eliminates the dust stratification on membrane wall pipe, enhances it
Heat conductivility, while hinder the formation being vortexed on deflector, reduce because vortex and to the abrasion of membrane wall pipe.
