Abstract
The utility model discloses a top pipe cap of boiler slag falling pipe which consists of stand bars, a base plate and a pipe cap; the top pipe cap of boiler slag falling pipe is characterized in that one ends of at least two stand bars are connected with the pipe cap and the other ends of the stand bars are connected with a slag falling pipe. The top pipe cap of boiler slag falling pipe adopts a round top pipe cap which can play the role of easing the slag falling speed more effectively; moreover, the round pipe cap can also lighten the self abrasion of the pipe cap and prolong the service life of the pipe cap.
Description
Technical field
The utility model relates to a kind of boiler slag dropping tube top pipe cap, relates in particular to the boiler slag dropping tube top pipe cap of a kind of suitable CFBB (CFB), belongs to the CFBB technical field.
Background technology
After boiler combustion is finished, lime-ash need be discharged boiler, general Slagoff method is by slag dropping tube slag to be drained into the boiler outside.
Slag dropping tube is the vitals that transports slag in the cold slag system of CFBB (CFB), and slag dropping tube top pipe cap is positioned at the burner hearth of furnace bottom air distribution plate upside, is connected with slag dropping tube.It act as the falling speed that reduces high temperature furnace slag, avoids high temperature furnace slag to directly the washing away of slag dropping tube, and alleviates in the slag dropping process wearing and tearing to slag dropping tube.What have in the prior art is not provided with the top pipe cap, and the pipe cap that has causes blocking slag dropping tube owing to design is unreasonable.
Summary of the invention
The purpose of this utility model provides a kind of more effectively playing and slows down slag speed, avoids blocking the boiler slag dropping tube top pipe cap of slag dropping tube.
For realizing above purpose, the technical solution of the utility model provides a kind of boiler slag dropping tube top pipe cap, comprises pipe cap and slag dropping tube, it is characterized in that, at least two leg one ends are connected with pipe cap, and the other end is connected with slag dropping tube.
Described pipe cap is a dome structure, and dome is provided with at least one hole slot, and the radius R of dome is 100mm-300mm; Connect by at least one backing plate transition between described leg and the pipe cap.
The utility model employing dome pipe cap can more effectively play and slow down the slag velocity function, and circular pipe cap also can alleviate the wearing and tearing of pipe cap self, prolongs its life-span.
Description of drawings
Fig. 1 is a kind of boiler slag dropping tube head tube cap schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be a kind of boiler slag dropping tube head tube cap schematic diagram, described a kind of boiler slag dropping tube top pipe cap is by leg 1, backing plate 2 and pipe cap 4 are formed, described pipe cap 4 is a dome, the radius R of dome is 100mm-300mm, open at least one hole on the pipe cap 4, in order to lime-ash is imported to slag dropping tube, leg 1 is the bending square steel that four an angle of 90 degrees are arranged, inserts the fluting place of slag dropping tube 5 upper ends, and leg 1 lower end is connected with the inner and outer wall of slag dropping tube 5, the weld seam at outer wall place is not easy to wear, and also play a supporting role to the top pipe cap in the slag dropping tube upper end simultaneously.And washing away when fallen by slag influences down, be difficult for causing the top pipe cap to come off, backing plate 2 is connected by bolt and nut 3 by two blocks of annular steel plates, the backing plate 2 of bottom is connected with leg 1 upper end, the backing plate 2 on top is connected with dome pipe cap 4, and backing plate 2 and dome pipe cap 4 can be connected or be connected together by bolt and nut 3.
Claims (3)
1. a boiler slag dropping tube top pipe cap comprises pipe cap (4) and slag dropping tube (5), it is characterized in that, at least two leg (1) one ends are connected with pipe cap (4), and the other end is connected with slag dropping tube (5).
2. a kind of boiler slag dropping tube according to claim 1 top pipe cap is characterized in that described pipe cap (4) is a dome structure, and dome is provided with at least one hole slot, and the radius R of dome is 100mm-300mm.
