Abstract
The invention discloses a method for detaching a tubular heat exchanger. The tubular heat exchanger comprises a cylinder, cards, tubearrays, and arm-ties, wherein the tubearrays are arranged in the cylinder longitudinally; the arm-ties are arranged in the cylinder; and two ends of the cylinder are provided with the cards which are welded with the cylinder in a sealed mode. The detaching method is as follows: firstly the tubearrays are cut to be separated inside the cylinder, and then the cards and the cylinder are cut to be separated. In the detaching method, the tubearrays can be cut from one side or from two sides simultaneously, and finally the arm-ties are removed. The method can not damage the whole heat exchanger, and the heat exchanger can be used again.
Description
Affiliated technical field
The present invention relates to a kind of method for dismounting of heat-exchange device.
Background technology
Can often use heat-exchanger rig in the Chemical Manufacture, especially be many with tubular heat exchanger, tubular heat exchanger is to arrange many heat exchanger tubes in socket, and heat exchanger tube and socket are separate to be two spaces, when different temperatures material flow during, promptly produce heat exchange through socket and tubulation.Because leaking very easily appears in tubulation in the heat exchanger, so just tubulation need be pulled down welded and installed again after the mending-leakage.But when heat exchanger was oversize, deviation dislocation often appearred in tubulation, made dismounting, encountered difficulties when welding is installed, and all be that the heat exchanger urceolus is cut open during dismounting, and then cut tubulation, and this causes the destruction of whole heat exchanger, can't utilize once more.
Summary of the invention
The invention provides a kind of method for disassembling tubular heat-exchanger, it can be avoided, and deviation appears in tubulation in the heat exchanger, makes the installation convenient welding.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of method for disassembling tubular heat-exchanger comprises tube, card, tubulation, arm-tie, and described tubulation vertically is arranged in the tube, is provided with arm-tie in the tube, and tube two ends are provided with card, and with the airtight welding of tube, earlier with tubulation cutting and separating internally, again with a card and a tube cutting and separating.
The above method for disassembling tubular heat-exchanger, described tubulation can also can cut from both sides simultaneously from cutting on one side, at last arm-tie is removed.
The present invention can not cause the destruction of whole heat exchanger, can utilize once more.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 for A-A among Fig. 1 of the present invention to schematic diagram.
Among the figure: 1. tin; 2. card; 3. tubulation; 4 arm-ties.
The specific embodiment
By accompanying drawing as can be known, the present invention includes tube 1, card 2, tubulation 3, described tubulation 3 vertically is arranged in the tube 1, and tube 1 two ends are provided with card 2, and with tube 1 airtight welding, on card 2, be provided with and tubulation 3 corresponding holes, and itself and tubulation 3 cross-shaped portions closely welded.Be provided with arm-tie 4 in the described tube 1, and arm-tie 4 is fixedlyed connected with tubulation 3.During dismounting, earlier with tubulation 3 cutting and separating internally, again with a card 2 and tube 1 cutting and separating, tubulation 3 can also can cut from both sides simultaneously from cutting on one side, at last arm-tie 4 is removed.
Claims (2)
1, a kind of method for disassembling tubular heat-exchanger, comprise tube (1), card (2), tubulation (3), arm-tie (4), it is characterized in that: described tubulation vertically is arranged in the tube (1), be provided with arm-tie (4) in the tube (1), tube (1) two ends are provided with card (2), and with the airtight welding of tube (1), earlier with tubulation (3) cutting and separating internally, again with card (2) and tube (1) cutting and separating.
2, according to the described method for disassembling tubular heat-exchanger of claim 1, it is characterized in that: described tubulation (3) can also can cut from both sides simultaneously from cutting on one side, at last arm-tie (4) is removed.
