Abstract
The utility model relates to a grip type compound tube plate high pressure heat exchanger, which is composed of a barrel body, a sealing head, a high pressure tube plate, a heat exchanger, a bearer interface, a material inlet, a material outlet and an interface, wherein, the high pressure tube plate is a thin tube plate; a corrosion resistant heat exchange tube bundle is connected with the thin tube plate in the expansion mode or welded with the thin tube plate; the bottom is provided with a sealing cushion layer and a bearing hole plate; the thin tube plate does the action of the isolation of the cauterization; the bearing hole plate does the action of the support of the strength. The utility model which is adopted is convenient in maintenance and low in cost and 1/3 of the cost is cheaper than the shell-and-tube heat exchanger with the same heat exchange area.
Description
The utility model belongs to chemical industry equipment class, the heat exchanger-type that is adopted specifically in chemical process flow.
In Chemical Manufacture, the technical process that need cool off or heat the higher fluid of pressure is often arranged, this process needs carry out in high pressure heat exchanger.When the process fluid non-corrosiveness, high pressure heat exchanger often adopts simple in structure, cheap U type pipe heat exchanger.When process fluid was corrosive, the then normal anti-corrosion heat exchanger of shell and tube with lining that adopts was as just extensively adopting this high pressure condenser in the vaporizing extract process urea production process flow process.Though this heat exchanger can satisfy the explained hereafter requirement, than U type pipe heat exchanger cost height, complex structure, manufacturing, maintenance difficult.
For the simple U type of bar structure tubular type calorimeter is used for the deep-etching occasion, in recent years, adopt the numerical control deep-hole welding machine to make high-pressure anticorrosion U type pipe heat exchanger abroad.Its concrete practice is to press the quantity perforate 16 of required tube bank earlier on the high pressure tube sheet, the more anti-corrosion built-up welding overlay 14 of weldering on the surface of high pressure tube sheet 3.Then welding wire is extend into the outside from high-voltage tube plate hole 14, anti-corrosion heat exchanger tube is butt-welded on the anti-corrosion built-up welding overlay of tube sheet, form weld seam 13 with the numerical control deep-hole welding machine.Though this technology has solved the corrosion-resistant problem of U type pipe heat exchanger, has the following disadvantages:
1, numerical control deep-hole welding machine price height extend into plumb joint from plate hole, and complex process is time-consuming, thereby causes the cost height of heat exchanger.
2, because welding wire stretches into welding from plate hole, and L is more little for tube plate thickness, and the plate hole diameter d is big more, to a certain degree then can't constructing, thereby there are the limit problem of a L/d ratio in good more welding, otherwise difficulty then, and showing external extreme value can only accomplish below 10.That is to say that the heat exchanger operating pressure is very high, the occasion that the heat pipe caliber is very little can not be used this method.
3, all tube bank is butt-welded on the tube sheet, and tube bank is little with the tube sheet contact-making surface, connects not fasteningly, and weld seam also easily goes wrong, once the very difficult reparation of ging wrong.
The purpose of this utility model is a deficiency of using the high pressure heat exchanger of numerical control deep-hole welding machine manufacturing at above-mentioned, designs the anti-corrosion heat exchanger of high pressure U type tubular type that new welding manner is arranged between a kind of tube sheet and the tube bank.
The purpose of this utility model realizes in the following manner, clipping clad tubesheet high pressure heat exchanger, be made of cylindrical shell 7, end socket 8, high pressure tube sheet 3, heat exchanger tube 11, heat exchanger is provided with heating or coolant carrier import and export 1, high-pressure material interface 9, high-pressure material import and export 12, cools off (heating) bearer interface 15.High pressure tube sheet 3 is a thin tubesheet, and sealing gasket 4 and pore 16 are arranged on the thin tubesheet all around, and the pore below has groove, and heat exchanger tube 11 inserts in the light wall pipe plate holes, and expanded joint or welding are thereon.One flanged 5 pressure-bearing orifice plate 18 is arranged below the high pressure tube sheet 3, and the tube head of heat-exchanging tube bundle is corresponding one by one on the hole on the pressure-bearing orifice plate and the high pressure tube sheet.Sealing bed course 17 is arranged between high pressure tube sheet 3 and the pressure-bearing orifice plate 18.
Content of the present utility model is described with reference to the accompanying drawings.
The high pressure heat exchanger that Fig. 1 adopts the numerical control deep-hole welding machine to make
Fig. 2 the utility model structural representation
With reference to accompanying drawing, high pressure tube sheet 3 adopts thin tubesheets, and the pipe number by heat-exchanging tube bundle on the thin tubesheet has hole 16, has taper or annular groove below the pore.In heat exchanger tube 11 patchholes 16, expanded joint or welding, or expand earlier and afterwards be welded on the high pressure tube sheet, groove is the weld seam 13 between plate, pipe.The utility model is convenient and strength-saving economical again from managing external welding, and welds from the bottom in the pipe insertion pore, and in conjunction with tight, good airproof performance has good corrosion-resisting function.
Have high pressure flange 5 and play that between the pressure-bearing orifice plate 18 of bearing strength effect and the high pressure orifice plate 3 thickness to be arranged be the flexible sealing bed course 17 of 0.1-3mm, guaranteeing the driving fit between the double layer of metal plate, and prevent cooling (heating) medium lateral flow and leak outside.Support ring 6 is arranged on the high pressure flange.Sealing gasket 4 is equipped with in high pressure tube sheet and high pressure cylindrical shell 7 junctions that have corrosion resistant material lining 10, and along with the difference of operating pressure in the high pressure cylindrical shell, this sealing gasket can be various plain cushions or formed mat.
Adopt the utility model maintenance convenient.Need only bolt 2 is unclamped, whole tube sheet and top heat exchanger tube can be taken out, though U type heat exchanger tube and the whole replacings of tube sheet is all very convenient, and this almost is impossible for two kinds of above-mentioned anti-corrosion heat exchangers.
The utility model cost is low, and under identical heat exchange area situation, this heat exchanger is cheap 1/3 than tubular heat exchanger, than the heat exchanger of Fig. 1 cheap 1/4.For example being used for heat exchange area of small-sized urea plant is 100m
2, the employing stainless steel is a corrosion-resistant material, and operating pressure is the tubular heat exchanger of 1.60MPa, and cost is approximately 450,000 yuan at present, and this heat exchanger under the equal conditions, its cost is less than 300,000 yuan.
