Abstract
一种带有中心管的组合式螺旋折流板换热器，用了内外侧螺旋折流板的组合结构。外侧和内侧之间设置一隔离圆筒。也可以在外折流板的外侧再设置数层外折流板，之间采用隔离圆筒隔开。为了防止短路，中间设置了内部带折流元件的中心管，折流元件可以是折流杆，也可以是弓形折流板和螺旋折流板。这种折流板有螺旋折流板的压降优势，也可以防止中心部位短路，而且，螺旋折流板的螺旋角度可以根据需要做的较大。这种换热器可以广泛应用在石油化工的装置上。
A combined spiral baffle heat exchanger with a central tube uses a combined structure of inner and outer spiral baffles. An isolation cylinder is arranged between the outer side and the inner side. It is also possible to arrange several layers of outer baffles on the outer side of the outer baffles, and use isolation cylinders to separate them. In order to prevent short circuit, a central tube with baffle elements inside is arranged in the middle, and the baffle elements can be baffle rods, bow baffles and spiral baffles. This kind of baffle has the advantages of the pressure drop of the spiral baffle, and can also prevent a short circuit at the center. Moreover, the helical angle of the spiral baffle can be made larger as required. This heat exchanger can be widely used in petrochemical equipment.
Description
Technical field
The utility model relates to a kind of industries such as oil, chemical industry, metallurgy, electric power that are applied to, and finishes the equipment of thermal medium exchange, and concrete is a kind of combined type spiral baffle heat exchanger that has central tube.
Background technology
At present, the useful plate of tube bank that known heat exchanger form is made up of heat exchanger supports, also there is straight-bar to support, with what plate supported forms such as arc, bouble-bow shape are arranged, and the pressure drop of adopting helical baffles to support is lower, heat transfer efficiency is higher, but for large diameter helical baffles, make difficulty, and be difficult for forming big angle.If the diameter of heat exchanger is very big, also form the phenomenon of short circuit easily.200420083360.4 of patent ZL are provided with central tube, and to the major diameter heat exchanger, the deflection plate angle is still very little, and it is best that effect can not reach.Patent 200710017395.6 is not provided with central tube, and the center short circuit problem is arranged, and does not have insulated cylinder between the internal and external parts, and media flow does not have water conservancy diversion, makes difficulty.The utility model is different from above-mentioned two kinds of spiral baffle heat exchangers.
The utility model content
Technical problem to be solved in the utility model is: the major diameter heat exchanger adopts the problem of helical baffles and central tube, should solve the simplification of manufacturing and the efficient performance of heat exchanger, solves the phenomenon of medium fluid short circuit again.The utility model aims to provide a kind of spiral baffle heat exchanger of the convenient band central tube of making.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of combined type spiral baffle heat exchanger that has central tube is provided, and by shell, tube sheet, heat exchanger tube, central tube, baffle groups constitutes.The outside is the external spiral deflection plate, and the inboard is the inside spin deflection plate.Also the outside of deflection plate is provided with several layers of outer deflection plate more outside, between the outer deflection plate of every circle an insulated cylinder is set.Inboard helical baffles can be provided with very big angle.The utility model adds central tube in the inboard, and to prevent the short circuit in centre, the central tube inboard is provided with segmental baffle, rod baffle, helical baffles.
Operation principle of the present utility model is: medium is also crossed outside helical baffles simultaneously by inboard helical baffles.Utilize the heat exchange property of helical baffles, improved the heat exchange efficiency of equipment.Effectively utilized the central tube part simultaneously.
Description of drawings
Accompanying drawing is the schematic diagram of the combined type spiral baffle heat exchanger of the utility model band central tube
Specific embodiments
1 is bobbin carriage in the accompanying drawing, and 2 is tube sheet, and with its fixing heat exchanger tube, 3 is shell, and 4 is helical baffles, and 5 is cylinder, and 6 is central tube, and 7 is interior deflection plate, and 8 for taking over, and 9 is skull, and 10 is heat exchanger tube.
The utility model is compared with known common spiral baffle heat exchanger, has adopted the combining structure of interior outside helical baffles, makes inboard spiral angle can do greatly, and the device fabrication difficulty reduces.That has utilized the low pressure drop of helical baffles and central tube prevents the centre short circuit, thereby improves the heat transfer efficiency of heat exchanger.
The utility model is simple, and the advanced person is reliable, can be widely used in fields such as oil, chemical industry not changing directly replacing tube bank under the integrally-built situation of heat exchanger, can promote the use of.
