Abstract
The utility model belongs to the technical field of auxiliary equipment of coal burning boilers and particularly relates to a pipe protecting device for a coal economizer, aiming at solving the technical problems that the pipe protecting device of the coal economizer of the existing circulating fluidized bed hot-water boiler influences the heat transfer of the pipe of the coal economizer, wastes materials and has a complex fixing means. The technical scheme is as follows: the pipe protecting device of the coal economizer comprises the pipes and supporting frames connected with the pipes, and also comprises straight protective tiles, small protective tiles, inner protective tiles and protective jackets, wherein the straight protective tiles and the inner protective tiles are movably connected with the pipes and bent positions of the pipes respectively through the small protective tiles arranged below the straight protective tiles and the inner protective tiles, one end of each of the straight protective tiles is connected with the supporting frames, and the straight protective tiles as well as the straight protective tiles and the inner protective tiles are connected through the protective jackets. The pipe protecting device has the advantages that the heat transfer of the pipes of the coal economizer is not influenced, the materials are saved, and the fixing means is simple.
Description
Technical field
The utility model belongs to coal-burning boiler auxiliary equipment technical field, is specifically related to a kind of economizer pipe protective device.
Background technology
Economizer is the main convection heating surface of recirculating fluidized bed hot-water boiler, and its reliability of operation is directly connected to the blowing out of boiler and user's economic benefit.Because fire coal circulating fluid bed boiler tail flue gas flow velocity height, more serious to the wearing and tearing of economizer pipe, as not taking safeguard measure, allow sweep of gases economizer pipe, then directly influence the service life of economizer pipe and the safety of boiler operatiopn.Traditional safeguard measure is to adopt to protect greatly watt to be fixed on the economizer tube, has had a strong impact on the heat transmission function of coal saving tube, has also caused the waste of material simultaneously, and the fixed form complexity, complex operation.
Summary of the invention
The purpose of this utility model is to exist at the economizer pipe protective device of present recirculating fluidized bed hot-water boiler to influence the heat transfer of economizer pipe, waste material and fixed form complicated technology problem, and a kind of heat transfer of economizer pipe, economical with materials and the simple economizer pipe of fixed form protective device of not influencing is provided.
The utility model is to address the above problem the technical scheme of taking to be:
A kind of economizer pipe protective device; comprise pipe, the bracing frame that is connected with pipe; wherein: also comprise directly protect watt, protect for a short time watt, in protect watt, sheath; described directly protect watt and in the watt-minute of protecting for a short time of protecting watt by being located at its below be not movably connected on the pipe on the crooked position with pipe; and an end that directly protects watt is connected with bracing frame, between directly protecting watt and directly protect watt with in be connected by sheath between protecting watt.
Protect in wherein said watt and to be arc.
The utility model adopts technique scheme, watt be installed in the one side that the economizer pipe is washed away with directly protecting, one end is connected with the economizer bracing frame, adopt sheath to be connected between directly protecting watt, and between directly protecting watt and directly protect watt, directly protect watt and the economizer pipe between all leave the gap, guarantee the free wxpansion of being heated of economizer pipe; In protect a watt crooked position that is installed in the economizer pipe, avoid the local weak influence of economizer pipe to total.Therefore, compared with prior art, the utlity model has does not influence the heat transfer of economizer pipe, economical with materials and the simple advantage of fixed form.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment 1:
As shown in Figure 1; a kind of economizer pipe protective device; the bracing frame 2 that comprise pipe 1, is connected with pipe; wherein: also comprise directly protect watts 3, protect watts 4 for a short time, protect in the arc watts 5, sheath 7; described directly protect watts 3 and arc in protect watts 5 by being located at the protecting for a short time on watts 4 crooked positions 6 that are movably connected in respectively on the pipe 1 with pipe 1 of its below; and directly protect an end of watts 3 and be connected with bracing frame 2, directly protect watts 3 between and directly protect watts 3 with arc in be connected by sheath 7 between protecting watts 5.
Claims (2)
1. economizer pipe protective device; the bracing frame (2) that comprise pipe (1), is connected with pipe; it is characterized in that: also comprise directly protect watt (3), for a short time protect watt (4), in protect watt (5), sheath (7); described directly protect watt (3) and in protect watt (5) by be located at the protecting for a short time of its below watt (4) and be movably connected in respectively that pipe (1) is gone up and the crooked position (6) of pipe (1) on; and an end that directly protects watt (3) is connected with bracing frame (2), directly protects between watt (3) and directly protect to protect between watt (5) in watt (3) and the arc to be connected by sheath (7).
2. a kind of economizer pipe protective device according to claim 1 is characterized in that: protect watt (5) in described and be arc.
