Abstract
The utility model discloses an abrasion-proof wind device for preventing the abrasion of the pipe wall of a circulating fluidized bed boiler, and belongs to the technical field of abrasion-proof wind devices. The abrasion-proof wind device comprises water wall tubes, fins and wind-supplying pipes, wherein the fins are connected between every two adjacent water wall tubes; round holes are formed in the fins at the upper part of a boiler concentrated phase area; the air outlet ends of the wind-supplying pipes are fixed in the round holes in the fins; the wind outlet of each wind-supplying pipe faces towards the center of a boiler chamber. According to the utility model, the holes are drilled into the fins on the water wall tubes at the upper part of the circulating fluidized bed boiler concentrated phase area, and the wind-supplying pipes are mounted at the drilling parts, so that a wind flow (abrasion-proof wind) is generated for preventing particles in smoke from abrading the water wall tubes, therefore, the abrasion is prevented and the problems are solved fundamentally.
Description
Technical field
The utility model relates to a kind of abrasionproof wind apparatus that prevents CFBB transducer wall ' s abrasion, belongs to abrasionproof wind apparatus technical field.
Background technology
CFBB abrading section mainly occurs in top, concentrated phase area, is a hard nut to crack of the art, up to the present, does not also obtain effectively, solves thoroughly.The existing Anti-wear Technology for CFBB abrading section has: 1. on pipe, add wearing-resistant tile; 2. spraying wear-resistant materials on pipe; 3. built-up welding; 4. lay castable.(5) dress abrasionproof crossbeam.Above-mentioned these methods are all passive abrasionproofs, and final pipe is still worn, and economic loss is huge.Affect safety, economical operation.
Summary of the invention
The purpose of this utility model is the problem existing in order to solve above-mentioned prior art, and existing anti-wearing method is all passive abrasionproof, and final pipe is still worn, and economic loss is huge.And then provide a kind of abrasionproof wind apparatus that prevents CFBB transducer wall ' s abrasion.
The purpose of this utility model is achieved through the following technical solutions:
A kind of abrasionproof wind apparatus that prevents CFBB transducer wall ' s abrasion, comprise: water screen tube, fin and ajutage, between described two adjacent water screen tubes, be connected with fin, on the fin on top, boiler concentrated phase area, have circular hole, the air opening end of described ajutage is fixed in the circular hole on fin, and the direction of ajutage air outlet is towards the center position of boiler furnace.
The utility model is to hole on the fin of the water screen tube on top, CFBB concentrated phase area, at boring sites in curing, airduct is installed, and produces distinguished and admirable (abrasionproof wind), stops the particle friction water screen tube in flue dust, has fundamentally prevented wearing and tearing.The utility model investment is little, easy construction, and the manufacture that is applicable to new boiler is produced, and is also applicable to the transformation of existing boiler operation.Investment be only equivalent to 300,000 of prior art/.
Brief description of the drawings
Fig. 1 is the cross-sectional view that the utility model prevents the abrasionproof wind apparatus of CFBB transducer wall ' s abrasion;
Fig. 2 is the cross-section cutaway view that the utility model prevents the abrasionproof wind apparatus of CFBB transducer wall ' s abrasion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under taking technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, a kind of abrasionproof wind apparatus that prevents CFBB transducer wall ' s abrasion that the present embodiment is related, comprise: water screen tube 1, fin 2 and ajutage 4, between described two adjacent water screen tubes 1, be connected with fin 2, on the fin 2 on top, boiler concentrated phase area, have circular hole 3, the air opening end of described ajutage 4 is fixed in the circular hole 3 on fin 2, and the direction of ajutage 4 air outlets is towards the center position of boiler furnace.
The interior diameter of described ajutage 4 is 16～18mm.
Blast in airduct is between 5000～9000Pa, and flow velocity, between 10～20m/s, adopts the existing blowing system of boiler, does not affect the normal operation of boiler.
The above; it is only preferably detailed description of the invention of the utility model; these detailed description of the invention are all the different implementations based under the utility model general idea; and protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
