Abstract
The utility model relates to a multi-stage open type spiral plate heat exchanger. The multi-stage open type spiral plate heat exchanger is a heat exchanger which is suitable for heating or cooling high viscosity fluid containing sand and stones and fiber impurities. 2-4 open type spiral bodies are connected in series to form the multi-stage open type screw plate heat exchanger. The spacing post support inside an open flow passage is changed into a flat steel or round steel support. When heat is exchanged, the high viscosity fluid passes through along an axial direction inside an open spiral flow passage, and a heated or cooled medium flows along a spiral direction. In this way, when the multi-stage open type spiral plate heat exchanger heats or cools the high viscosity fluid containing impurities, the multi-stage open type spiral plate heat exchanger can not be blocked. Except that the multi-stage open type spiral plate heat exchanger is used for heating or cooling the high viscosity fluid, the multi-stage open type spiral plate heat exchanger can be used as a condensing heat exchanger.
Description
The utility model relates to heat exchange to be transferred fully, especially for the spiral-plate heat exchanger of heating or cooling high viscosity fluid.
In decades,, can hang down characteristics such as temperature difference heat exchange, volume is little, manufacturing is simple, in every profession and trade, be used widely because spiral-plate heat exchanger has the heat transfer coefficient height.
Spiral-plate heat exchanger is a kind of heat exchanger with special heat-transfer area structure, and it is to be made by while coiling shape by two blocks of parallel steel plates.Roll two concentric channels of formation in the process at heat exchanger, each passage is the single passage of ring-type, and its cross section is a rectangle.Import and export and take over the marginal end that is loaded on two passages respectively.For keeping the spacing of passage, improve the rigidity and the bearing capacity of spiral plate, increase the heat exchange effect, in two lead to, arranged many cylindrical spacing columns.
At present, the spiral-plate heat exchanger of producing both at home and abroad is single leptospira structure.Spiral-plate heat exchanger by shell, spiral plate heat exchange body (abbreviation conveyor screw), seal and import and export four parts and form.Different according to channel arrangement and service condition can be divided into non-disconnectable, removable and three kinds of open types.Wherein the full weldering in the two ends of a passage of open type spiral-plate heat exchanger is dead, and the two ends of another passage are opened wide entirely, and the inner fluid passage dead in weldering flows in the shape of a spiral, and another fluid is only made axial flow.Traditional open type spiral-plate heat exchanger, during as the high viscosity fluid heat exchange, high viscosity fluid flows vertically, and heating or cooling medium then flows along the hand of spiral, and flow and the heat exchange of two media all push the wrong stream and carry out.In above-mentioned heat transfer process, since heating or cooling medium therefrom mind-set excircle helical flow or from excircle to center flow, this just certainly will cause the temperature that is heated or cooled medium in the shaft orientation flowing channel different along radial direction in outlet, form heat transfer temperature difference, influenced the heat exchange effect; In addition, impurity such as the fiber in the high viscosity fluid very easily twine on retardance and the horizontal spacing column in runner, so that result in blockage.
The purpose of this utility model provides a kind of heat exchange effectively, and reduces heat transfer temperature difference, makes the outlet temperature of fluid basic identical, and high sticking material is circulated smoothly, thereby avoids the open type spiral-plate heat exchanger that stops up.
The utility model can be realized by following measure; This open type spiral-plate heat exchanger, the top that is included in shell is provided with charging aperture, there is discharging opening the below, be equipped with the spiral plate type heat-exchanger rig in the enclosure, this spiral plate type heat-exchanger rig is made of 2-4 conveyor screw series connection, each conveyor screw all is provided with and opens wide runner and sealing runner, is furnished with band steel or round steel and supports in opening wide runner.
The purpose of this utility model also can realize by following measure: be provided with the pipeline that cooling or thermal medium circulate mutually between the outside of shell or 2 conveyor screws in the shell.Be provided with the dividing plate of perforate in the center of opening wide runner.The upper cover of shell, low head connect with flange respectively, in addition, also adopt flange to connect with respect to the shell between two conveyor screws.Be respectively equipped with inspection opening at upper cover and on respect to the shell between two conveyor screws.
The utility model is compared with prior art:
1, a plurality of (be generally 2-4) open type spiral plate heat exchange body is combined in series, allow heating or cooling medium in these heat exchange bodies respectively therefrom the mind-set excircle flow and from excircle to center flow.Like this at the different radii place, if it is higher relatively to be heated or cooled medium temperature in first conveyor screw outlet, it is just relatively low to be heated or cooled medium temperature second conveyor screw outlet so, be heated or cooled medium through-flow and when going out, its temperature is basic identical along radial direction in last conveyor screw thereby make.
2, for to prevent that the impurity such as fiber that contain in the high viscosity fluid from hanging on the spacing column, the utility model supports the band steel (or round steel) that the cylinder perpendicular to axial direction in the open channels changes the whole piece of axial setting into, thereby has overcome the defective that existing spiral-plate heat exchanger can not be handled the high viscosity fluid that contains impurity.
3, when being connected the each several part of shell, both can use flange, also can directly weld.If adopt Welding Structure, only need to set up a manhole on each conveyor screw top, just can overcome the shortcoming of general spiral-plate heat exchanger maintenance difficulty.In addition, connect as adopting flange, just can further make things convenient for maintenance and local replacing.
4, because band steel supports 19 contacts closely with spiral plate, so objectively also played the expansion heat exchange area, the effect of enhancing heat exchange effect.
In a word, heat exchanger structure described in the utility model is simple, maintenance is convenient, and the high viscosity fluid heating and cooling that are suitable for containing impurity are used, and do not produce stop up and temperature deviation extremely low.In addition, can also use as condenser, at this moment, the cooling medium helical flow path of flowing through, the fluid that is condensed then flow in opening wide runner vertically.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of an embodiment of multistage open type spiral-plate heat exchanger; Fig. 2 is the partial enlarged drawing of Fig. 1; Fig. 3 is the A-A cutaway view of Fig. 1; Fig. 4 is the partial enlarged drawing of Fig. 3.This accompanying drawing is depicted as a two-stage open type spiral-plate heat exchanger that is used for alcohol industry, is used for cooling off the converted mash of impurity such as containing sandstone, fiber specially.
This heat exchanger mainly is made up of 2 (promptly upper and lower) conveyor screws 4.Its structure is open type, and promptly (claiming to open wide runner 6) all opened wide with another runner of round steel 18 welderings dead (claiming sealing runner 7) in runner two ends.Be furnished with spacing column 9 in the sealing runner 7, open wide and be furnished with band steel support 19 in the runner 6.Conveyor screw 4 joins with shell 3 respectively, and shell 3 is welded with cylindrical shell by upper cover 8, low head 2, has charging aperture 10 and inspection opening 5 on the upper cover 8, has discharging opening 1 on the low head 2.The vertical installation of equipment, supported by the bearing 17 that is welded on the shell 3, need the converted mash of cooling to enter from charging aperture 10, at first through-flow is by the unlimited runner 6 of the conveyor screw 4 on top, enter the unlimited runner 6 of the conveyor screw 4 of bottom then, discharge from discharging opening 1 at last.Because the material road is bigger in space, center circle place, for preventing medium, so the dividing plate 11 of perforate all is housed at the center that each conveyor screw 4 opens wide runner 6 in this " short circuit ".Cooling water enters the conveyor screw 4 of bottom by water inlet base 16, and helical flow from inside to outside enters the water inlet base 12 on top then through water outlet base 15 flow ipes 14.The conveyor screw 4 that cooling water enters top by this base 12 is helical flow from outside to inside, discharges through water outlet base 13 then.Converted mash flows from top to bottom in whole heat transfer process, and cooling water can be obtained better cooling effect from flowing down, then belongs to the cross-flow heat exchange in each conveyor screw 4.Because the cooling-water flow direction is opposite in the conveyor screw 4 of upper and lower part, thereby avoided conveyor screw 4 outlets of converted mash to take place along the different phenomenon of radial direction temperature in the bottom.For fiber, the sandstone that solves in the converted mash stops up heat exchanger, this heat exchanger has been done following change to the structure of spacing column: the spacing column 9 of cooling water runner still adopts traditional cylinder spacing column, and the converted mash runner adopts the width band steel identical with unlimited runner 6 spacings of conveyor screw 4 to support 19.The length of band steel support 19 is identical with the height of conveyor screw 4, is arranged vertically in unlimited runner 6.
The form that this heat exchanger also can take cold or hot medium pipeline 14 to be located between 2 conveyor screws 4 in the shell 3 is implemented.
