Description
Technical field
The utility model relates to a kind of HTGR steam generator heat exchange tube fixed sturcture, efficiently solves problems such as heat exchanger tube vibration, thermal stress, fixed support difficulty, is convenient to install, and has improved the work efficiency of installing greatly.
Background technology
The HTGR steam generator heat exchange tube is the core component of evaporator, and can heat exchanger tube operate as normal be directly connected to the overall performance of evaporator, but occur problems such as heat exchanger tube vibration, thermal stress, fixed support, difficult installation easily.Though Germany's design once disclosed the evaporator of major diameter coil pipe, it belongs to the mounting means of non-assembly type, and the gap is big between pipe, and fixed support is relatively easy.And for the evaporator of middle coil pipe, the fixed form of big coils is no longer suitable, and the heat exchanger tube stationary phase is to difficulty.
At present, do not see relevant report about the technology of this respect.How in limited space, to solve problems such as tube vibration, thermal stress, fixed support, difficult installation, become the technical matters that the design of heat exchanger tube fixed sturcture needs to be resolved hurrily.
The utility model content
In view of above-mentioned present situation; The utility model provides a kind of fixed sturcture of HTGR steam generator heat exchange tube; Through reasonable installation configuration, significantly reduce installation time, improve the assembly work work efficiency; In the finite space, efficiently solve problems such as heat exchanger tube vibration, thermal stress, fixed support, difficult installation.
According to the utility model, the fixed sturcture of HTGR steam generator heat exchange tube comprises heat exchanger tube, at the load-bearing bar of heat exchanger tube side direction or bottom, at the fixed strip and the gib screw between heat exchanger tube side direction or heat exchanger tube on heat exchanger tube side direction or top.
The following specifically describes the utility model.
In the utility model, said heat exchanger tube is the heat exchanger tube that is used for the HTGR steam generator, is the core component of mid-game tubular evaporator, occurs problems such as heat exchanger tube vibration, thermal stress, fixed support, difficult installation in actual use easily.For adapting to the heat exchanger tube vibration and supporting, the effective pretightning force of reply working condition guarantees that heat exchanger tube well contacts, reduces vibration with miscellaneous part; And assembling is quick, safety, shortens installation time and also reduces installation difficulty, all need exchange heat pipe and fix, and guarantees the heat exchanger tube operate as normal, and this also is directly connected to the overall performance of evaporator.
In the HTGR steam generator, generally be designed to many heat exchanger tubes and lay side by side, form heat-exchanging tube bundle or set of heat exchange tubes.For they are fixed, according to the utility model, be provided with the load-bearing bar in heat exchanger tube side direction or bottom, be provided with fixed strip in heat exchanger tube side direction or top, and between the both sides of heat exchanger tube or heat exchanger tube, be provided with gib screw.
In the utility model, heat exchanger tube load-bearing bar generally is positioned at heat exchanger tube or heat-exchanging tube bundle side direction or bottom, and major function is to support heat exchanger tube, bears medium-weight in heat exchanger tube and the heat exchanger tube, guarantees the heat exchange tube structure size, reduces the vibration of heat exchanger tube.Heat exchanger tube load-bearing bar can be M shape or I shape, and form is pretightning force size and resilience size and confirm that width and thickness are definite according to stressing conditions as requested.In the utility model, the shape of heat exchanger tube load-bearing bar is preferably I shape.
In the utility model, the heat exchanger tube fixed strip generally is positioned at heat exchanger tube or set of heat exchange tubes top, relatively clamps heat exchanger tube with heat exchanger tube load-bearing bar, improves the pretension effect, plays fixation.Similar with heat exchanger tube load-bearing bar, fixed strip also can be M shape or I shape, and its shape depends primarily on heat exchange tube diameter and tube pitch, also depends on requirement pretightning force size and resilience size, and width and thickness are decided according to stressing conditions.In the utility model, the shape of heat exchanger tube fixed strip is preferably M shape.
In the utility model, the effect of heat exchanger tube gib screw is that fixed strip is compressed, thereby prevents that heat exchanger tube from moving horizontally, but also can the pretension heat exchanger tube, lets the heat exchanger tube fixed strip produce elastic deformation, so as still can be effectively during operation fixing heat exchanger tube.
Set bolt can be positioned at the both sides of set of heat exchange tubes, promptly is positioned at a side of edge heat exchanger tube, also can be between heat exchanger tube, and this depends primarily on the position of its heat exchanger tube that will fix itself.Gib screw between heat exchanger tube can be one or more, perhaps the many shared gib screws of heat exchanger tube.Screw size and quantity decide according to pretightning force and heat exchanger tube size and space, that is to say, according to the different-diameter of heat exchanger tube, can select the gib screw of different size and varying number.
According to the utility model; Adopt the bolt connecting mode of gib screw to make heat exchanger tube fixed strip and heat exchanger tube load-bearing bar produce certain bullet (moulding) property distortion with certain prestress; Preferred heat exchanger tube gib screw connects heat exchanger tube fixed strip and load-bearing bar with firmly beforehand means, and bullet (moulding) the property distortion that produces of its pretightning force can the compensation work state under heat exchanger tube shrink the heat exchanger tube that causes relatively and become flexible.
In the utility model, heat exchanger tube fixed strip and load-bearing bar are M shape or I shape.For M shape fixing heat exchanger tube fixed strip or heat exchanger tube load-bearing bar, for increasing bullet (moulding) property deformation that pretightning force causes and the stress level that reduces bolt fastening structure, itself and heat exchanger tube position contacting arc radius should be greater than heat exchanger tube radius 0-50mm.
According to the utility model, heat exchanger tube gib screw, heat exchanger tube fixed strip, heat exchanger tube load-bearing bar and heat exchanger tube (or heat-exchanging tube bundle or group) can make up use in a variety of forms, and concrete type selecting combines practical application to confirm.In these array modes; Preferred heat exchanger tube load-bearing bar be shaped as I shape, and the heat exchanger tube fixed strip be shaped as M shape, in the case; The top of gib screw can not protrude from the fixed strip surface level, thereby can not hinder on one group of heat exchanger tube another group heat exchanger tube again.
The fixed sturcture of the HTGR steam generator heat exchange tube that the utility model provides, the evaporator of having filled up middle coil pipe is the technological gap of aspect fixedly, and the fixed sturcture of the utility model can guarantee that evaporator connects the heat exchanger tube operate as normal; Effectively fixing heat exchanger tube; Satisfy heat exchanger tube vibration and support, also can satisfy the effective pretightning force of working condition, guarantee that heat exchanger tube well contacts, reduces vibration with the load-bearing bar; Help more effectively assembling, thereby reduce installation time and difficulty.
