Abstract
A boiler hood relates to the field of smoke discharge, in particular to a hood of a chimney of a boiler, which comprises a hood and a windproof cap in the hood. The boiler hood is characterized in that the hood consists of an upper chimney 1, an upper conical cylinder 2, a lower cylinder 3 and a lower chimney 4, wherein the diameter of the lower conical cylinder 2 is larger than that of the lower chimney, the lower conical cylinder is connected with the lower chimney via three to four supporting plates 6 which are radially distributed uniformly, and the windproof cap 5 is arranged at the center of the lower conical cylinder 3 via the supporting plate 6. Besides, the windproof cap 5 is in hopper shape. The hood arranged at the inlet of the chimney is convenient in maintenance and can not affect smoke discharging effect of the chimney. In addition, the hopper-shaped windproof cap can collect condensed water in the chimney, thereby preventing chimney corrosion or influencing extraction force of the chimney.
Description
Technical field
The utility model belongs to the smoke evacuation technical field, relates to the petticoat pipe of the chimney of boiler.
Background technology
Boiler in heating, to provide aspect the hot water be important equipment.The fuel of boiler mainly contains coal, oil, combustion gas, uses the sort of fuel boiler all to need smoke evacuation.The general chimney that uses of smoke evacuation, the length of chimney has a significant impact the work of boiler, chimney has been lacked and has been caused down row easily, chimney has grown that to be easy to generate draft excessive, therefore earthquake is added with petticoat pipe mostly than the chimney of the medium small boiler that uses in the overall situation, petticoat pipe can prevent down row, and it is excessive also can to suppress draft, can also block dropping of foreign matter.The petticoat pipe of present most of chimneys is arranged on chimney outlet, causes smoke to disperse, if chimney is too short, also influences the draft of chimney; And petticoat pipe out of doors, causes damage easily.
Summary of the invention
The purpose of this utility model is to provide a kind of petticoat pipe that is arranged on the chimney porch, can avoid the drawback of conventional petticoat pipe.
To achieve these goals, the utility model has been taked following technical scheme: a kind of boiler petticoat pipe, constitute by anti-blast cap in cover body and the cover body, cover body is made up of last chimney, upper conical-tube, slower conical tube, lower stack successively, wherein, the diameter of slower conical tube is greater than the diameter of lower stack, and slower conical tube is connected by 3 to 4 radially equally distributed gripper shoes with lower stack, and anti-blast cap is arranged on slower conical tube central authorities by gripper shoe.
Anti-blast cap wherein is set to the infundibulate opposite with conventional petticoat pipe.
Compare with existing petticoat pipe, the utlity model has following advantage: petticoat pipe is arranged on the porch of chimney, is convenient to safeguard; Do not influence the smoke effect of chimney.Anti-blast cap is an infundibulate, can collect the condensed water in the flue dust, avoids corroding chimney; And do not influence the draft of chimney.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, go up chimney, 2, upper conical-tube, 3, slower conical tube, 4, lower stack, 5, anti-blast cap, 6, gripper shoe.
The specific embodiment
When petticoat pipe used, lower stack 4 was connected with boiler, last chimney 1 with stretch out outdoor chimney and be connected.
Claims (2)
1. boiler petticoat pipe, constitute by anti-blast cap in cover body and the cover body, it is characterized in that: cover body is made up of last chimney (1), upper conical-tube (2), slower conical tube (3), lower stack (4) successively, wherein, the diameter of slower conical tube (3) is greater than the diameter of lower stack (4), slower conical tube (3) is connected by 3 to 4 radially equally distributed gripper shoes (6) with lower stack (4), and anti-blast cap (5) is arranged on slower conical tube (3) central authorities by gripper shoe (6).
2. a kind of boiler petticoat pipe according to claim 1 is characterized in that: described anti-blast cap (5) is an infundibulate.
