Abstract
A kind of mounting structure of abrasionproof pipe, comprise two abrasionproof pipes, described abrasionproof pipe one end is 90 ° of elbows, the other end keeps straight tube, one distolateral circumference soldering I on wallboard of described straight tube, the other end of straight tube is through wallboard II, by wallboard, II provides support power, 90 ° of elbows of described two abrasionproof pipes are welded and fixed, the curved elbow in 90 ° in one end of the utility model abrasionproof pipe, the other end keeps straight section, flow development length is greater than the distance between two end wall panels, only straight length end and a framed side wallboard circumference soldering, when the sagging plate not with its welding, 90 ° of elbow butt welding of the two abrasionproof pipes in wallboard outside, form 180 ° of elbows, be equivalent to fixedly one end, other end elbow can be free, thereby guaranteed that abrasionproof pipe has enough thermal expansion spaces, also can not make equipment produce stress concentrates, some weld bonds have been reduced simultaneously, so both reached the object that guarantees equipment safety operation, also saved production cost.
Description
Technical field
The utility model belongs to thermal power plant design field, is specifically related to the mounting structure of the abrasionproof pipe installed in a kind of economizer.
Background technology
Abrasionproof pipe is generally arranged on economizer and meets cigarette side, and before heat exchanger tube, totally two rows, when flue gas blows, directly wash away abrasionproof pipe, thereby protection heat exchanger tube below extends heat exchanger tube service life and prevents that heat exchanger tube wearing and tearing from leaking, thereby guarantees the safe operation of economizer.
When abrasionproof pipe is installed at present, it is directly welded between two end wall panels, and with the middle all-round welding of tube sheet, although this installation form does not affect abrasionproof function, but due to wallboard and sagging plate be all circumference soldering, be that abrasionproof pipe is completely fixed, cause not having the space of thermal expansion, smoke gas flow temperature when low province equipment is about 130 ~ 150 ℃, now, abrasionproof pipe must have thermal expansion, but because its two ends are all welded and fixed, there is no expansion space, will concentrate with wallboard and sagging plate junction generation stress, in long playing situation, will cause very large hidden danger to the safe operation of equipment.
Summary of the invention
In order to address the deficiencies of the prior art, in order to make abrasionproof pipe can have enough thermal expansion spaces when equipment normally moves, prevent from concentrating with the junction generation stress of wallboard and tube sheet, the present invention is by making the curved elbow in 90 ° in one end of abrasionproof pipe, and be that the issuable thermal expansion of abrasionproof pipe retains expansion space, and take to reduce weld bond technological means, thereby guaranteed that abrasionproof pipe has enough thermal expansion spaces, also can not make equipment produce stress concentrates, both reach the object that guarantees equipment safety operation, also saved production cost.
For achieving the above object, the utility model is by realizing by the following technical solutions: a kind of mounting structure of abrasionproof pipe, comprise two abrasionproof pipes, described abrasionproof pipe one end is 90 ° of elbows, the other end keeps straight tube, distolateral circumference soldering I on wallboard of described straight tube, and the other end of straight tube is through wallboard II, by wallboard, II provides support power, and 90 ° of elbows of described two abrasionproof pipes are welded and fixed.
Preferably, the abrasionproof pipe between described wallboard I and wallboard II also, through sagging plate, provides support power by sagging plate.
Preferably, in described abrasionproof pipe, the length of straight tube is greater than the distance between wallboard I and wallboard II.
The beneficial effects of the utility model are: the curved elbow in 90 ° in one end of the utility model abrasionproof pipe, the other end keeps straight section, the flow development length of abrasionproof pipe is greater than the distance between two end wall panels, and only straight length end and a framed side wallboard circumference soldering, when the sagging plate not with its welding, 90 ° of elbow butt welding at the two abrasionproof pipes in another side wallboard outside, form 180 ° of elbows, 3 road weld bonds are only set, not middle not being fixedly connected with any tube sheet and wallboard, be equivalent to fixedly one end, other end elbow can be free, thereby guaranteed that abrasionproof pipe has enough thermal expansion spaces, also can not make equipment produce stress concentrates, some weld bonds have been reduced simultaneously, so both reached the object that guarantees equipment safety operation, also saved production cost.
Accompanying drawing explanation
Fig. 1 is the mounting structure structure structural representation of a kind of abrasionproof pipe of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of mounting structure of abrasionproof pipe, comprise two abrasionproof pipes, described abrasionproof pipe one end is 90 ° of elbows, the other end keeps straight tube, one distolateral circumference soldering I on wallboard of described straight tube, the other end of straight tube is through wallboard II, by wallboard, II provides support power, 90 ° of elbows of described two abrasionproof pipes are welded and fixed, abrasionproof pipe between described wallboard I and wallboard II is also through sagging plate, by sagging plate, provide support power, in described abrasionproof pipe, the length of straight tube is greater than the distance between wallboard I and wallboard II, during use, heat exchanger tube is fixed on inner side, 90 ° of elbows of abrasionproof pipe, the curved elbow in 90 ° in one end of the utility model abrasionproof pipe, the other end keeps straight section, the flow development length of abrasionproof pipe is greater than the distance between two end wall panels, and only straight length end and a framed side wallboard circumference soldering, when the sagging plate not with its welding, 90 ° of elbow butt welding at the two abrasionproof pipes in another side wallboard outside, form 180 ° of elbows, 3 road weld bonds are only set, not middle not being fixedly connected with any tube sheet and wallboard, be equivalent to fixedly one end, other end elbow can be free, thereby guaranteed that abrasionproof pipe has enough thermal expansion spaces, also can not make equipment produce stress concentrates, some weld bonds have been reduced simultaneously, so both reached the object that guarantees equipment safety operation, also saved production cost.
Obviously, above-mentioned embodiment is only better embodiment of the present utility model, and any simple modifications on this basis all belongs to protection domain of the present utility model.
