Abstract
The utility model discloses an end shock-proof structure of a winding pipe type heat exchanger, comprising a pipe plate which is connected with the pipe opening of each heat exchanging pipe. The end shock-proof structure of a winding pipe type heat exchanger is characterized in that a plurality of shock-proof rings which are matched with the outer diameter of the straight segment of a heat exchanger are sheathed outside the straight segment of the heat exchanger on the inner side of the pipe plate at intervals. Each shock-proof ring is connected with the pipe plate by at least a pair of shock-proof strips which are axially arranged. Each pair of shock-proof strips can be symmetrically arranged, and the end position of the straight segment of the heat exchanger is best provided with a shock-proof ring. Compared with the prior art, the utility model has the advantages that after the structure is adopted, the shock of the heat exchanger under various occasions can be effectively reduced, and technology heat transfer and flow resistance can not be influenced. Therefore, the end shock-proof structure of a winding pipe type heat exchanger is the end shock-proof structure which has good shock-proof effect and long equipment service life. The end shock-proof structure of a winding pipe type heat exchanger ultimately enhances the application quality of the heat exchanger under various occasions, and the application of the heat exchanger is wider.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially refers to the end shockproof structure in a kind of wrap-round tubular heat exchanger.
Background technology
Wrap-round tubular heat exchanger is as a kind of efficient, energy-conservation heat exchanger, be widely used in chemical fertilizer plant, gas fractionation units etc. are big-and-middle-sized, in the mesohigh heat transmission equipment, it is mainly by around the tube core body, housing two parts are formed, wherein, around the tube core body is the core component of wrap-round tubular heat exchanger, it is again by heat exchanger tube, revolving body, in length and breadth to compositions such as spacing structures, each heat exchanger tube port is located mutually by a tube sheet again, in use, in order to prevent to be subjected to the vibrations that influences such as shell side side medium impact cause down, in order to avoid the damage of aggravation heat exchanger, usually the appearance wrapping at heat exchanger tube has steel band, promptly adopt the way of steel band wrapping to carry out shockproof around the end of tube core body, but this shockproof structure is found after use: during 1. owing to the equipment operation cold and hot variation will take place, therefore, the fastening effect of steel band wrapping can be along with equipment operation and loosening gradually, so that can not fastening effectively each heat exchanger tube; Exist the characteristics of oppositely twining between layer and the layer during 2. owing to the heat exchanger tube coiling, therefore with between one deck heat exchanger tube, layer with layer heat exchanger tube between all exist the gap, this gap is along with the operation meeting break-in gradually of equipment, causes end shape around the tube core body to change and the steel band wrapping was lost efficacy; 3. because there is non-flat straight section in the heat exchanger tube of end surface, therefore the steel band of wrapping at it outside will be to this non-flat straight section generation additional limits, when heat exchanger tube takes place under cold and hot state axially, during radial displacement, obvious above-mentioned restriction will damage the outer surface of heat exchanger tube; 4. lost efficacy or loosening after steel band will aggravate the damage of heat exchanger tube.Therefore the shockproof effect of said structure is not obvious, has influenced the service life of equipment simultaneously, so still await further improvement.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and the end shockproof structure of the wrap-round tubular heat exchanger that a kind of shockproof effect is good, service life of equipment is long is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the end shockproof structure of this wrap-round tubular heat exchanger comprises the tube sheet that links to each other with each heat exchanger tube mouth of pipe, it is characterized in that: the compartment of terrain is with a plurality of bump protection rings that match with its external diameter outside the heat exchanger flat segments of described tube sheet inboard, and each bump protection ring links to each other with this tube sheet by at least one pair of axial arranged shockproof.
Described every pair shockproof preferably is symmetrically distributed in heat exchanger flat segments appearance.
The flat segments end of described heat exchanger is good to be provided with bump protection ring.
Compared with prior art, advantage of the present utility model is: after adopting said structure, can reduce the vibrations of heat exchanger under various occasions effectively, and neither influencing technology conducts heat and flow resistance, can prolong the service life of heat exchanger again, therefore the utility model helps improving the application quality of this heat exchanger under various occasions, makes its application wider.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this wrap-round tubular heat exchanger comprises central tube 2 and is wound in the outer heat exchanger tube 6 of central tube, each place, heat exchanger tube end is flat segments, and each mouth of pipe is by a tube sheet 1 location, and end shockproof structure employing compartment of terrain outside the heat exchanger flat segments is with a plurality of bump protection rings 5 that match with its external diameter, and in the present embodiment, bump protection ring 5 is two, also can be three or four, each bump protection ring links to each other with this tube sheet by one or more pairs of axial arranged shockproof 4.In order to have better shockproof effect, every pair shockproof 4 preferably is symmetrically distributed, and is provided with bump protection ring in the end 7 of heat exchanger flat segments.
Add man-hour, insert interim connecting pin 3 earlier in the end of central tube 2, by the good heat exchanger tube of existing technology coiling, put bump protection ring 5 as required at the flat segments place of heat exchanger tube end then, then each heat exchanger tube mouth of pipe is fixed on the tube sheet 1, again will corresponding shockproof 4 axially be placed on outside the bump protection ring 5, itself and each bump protection ring 5 and tube sheet 1 are fused with welding manner, extract interim connecting pin 3 at last out, can make the heat exchanger that has the end shockproof structure.
