Description
Technical field the utility model relates to the tubulation air preheater that carries out exchange heat between a kind of air preheater, particularly high-temperature flue gas and multimedium.
Background technology is present, heat-pipe air preheater is widely used in oil, chemical industry, in the reheating furnace energy-saving equipment of industries such as metallurgy, but the flue gas medium temperature that many operating modes are arranged is than higher, for preventing the too high booster that takes place of heat pipe Yin Wendu, people once adopted and reduce the heat pipe wall temperature and promptly reduce the work medium for heat pipe that fume side heat exchange area or selection are suitable for higher temperature, their weak point is: if the former reach, and identical exchange capability of heat just needs the volume of increase equipment, its working media freezing point of the latter's high-temperature heat pipe is higher, in the low delay that easily causes internal working medium of temperature, perhaps heat-transfer working medium is solidified, and influence heat transfer property at cold junction.Therefore people adopt tubular heat exchanger during worst hot case, and increase the turbolator sheet in the tubulation and strengthen heat exchange area; Or link to each other with tubular heat exchanger before adopting the heat-pipe air preheater smoke-box, but for a kind of medium of preheating is well-adapted, for the heat exchange of heat pipe that carries out exchange heat simultaneously with multimedium, if adopt split type, cost is higher relatively, need take bigger space.
The summary of the invention the purpose of this utility model is to provide a kind of high-temperature flue gas simultaneously to carry out exchange heat with multiple medium, and the whole tubular heat exchanger of heat transfer efficiency height, long service life, the exchange heat between high-temperature flue gas little, that cost is low and multimedium of taking up room.
The utility model mainly includes: heat exchanger tube, tube sheet, Shell Plate, flue gas and medium are imported and exported assembly.Wherein, heat exchanger tube is a tubulation, the tubulation that the augmentation of heat transfer turbolator is arranged preferably, this tubulation can be a light pipe, but the preferably outer finned tube that the expansion heat-transfer surface is arranged, this fin can be helical fin, fin, fin, H type fin and studded tube etc., is preheated medium to walk in the pipe, and high-temperature flue gas is walked outside the pipe.Above-mentioned some heat exchanger tubes are formed heat-exchanging tube bundle, the heat-exchanging tube bundle two ends that this is the level of state are located at respectively on the vertical tube sheet of the two rectangles through hole corresponding with it, if medium is non-inflammable, explosive, toxic gas, heat exchanger tube one end is fixed on the tube sheet, the other end can be fixed on the tube sheet, also can flexibly connect with tube sheet, for satisfying the requirement of expanding with heat and contract with cold, be provided with arc or flexible connection in the tube sheet outside that is fixed with heat exchanger tube, it is flexible that it can be varied with temperature.Above-mentioned tube sheet dual-side links to each other with two vertical Shell Plate dual-sides respectively, constitute up and down for the rectangular tubular casing of opening is the heat exchanger tube chamber, above-mentioned tube sheet or Shell Plate can be a whole plate from top to bottom, also can be two boards, be linked to be one during installation, superelevation when preventing to transport.The upper shed of above-mentioned Heat Room casing links to each other with high-temperature flue gas import assembly one end, and under shed links to each other with high-temperature flue gas spout assembly one end, and flue gas is perpendicular flow from top to bottom.On the tube sheet of above-mentioned casing both sides, be provided with three kinds of corresponding media and import and export assembly, be that a kind of medium import and export assembly is established in the bottom, top is established two media and is imported and exported assembly, and the end that these three kinds of media are imported and exported assembly links to each other with tube sheet respectively, and the heat exchanger tube on the tube sheet is divided into three parts.Too high because of flue-gas temperature, be preferably in the side that tube sheet, Shell Plate and smoke entrance assembly contact with flue gas and be equipped with the exotic material layer; Medium is imported and exported between assembly and the tube sheet and also is respectively equipped with the rectangle heat proof material ring corresponding with it.
The utility model is when work, carry out exchange heat with heat exchanger tube in the process that high-temperature flue gas is advanced from the top down, soon its heat that carries is passed to the medium in each heat exchanger tube, so temperature raises after entering the interior cold medium absorption heat of heat exchanger tube, reaches the purpose with their preheating; And high-temperature flue gas from the top down gradually the cooling discharge from exhanst gas outlet then.
The utility model compared with prior art has following advantage:
1, the utility model separated heat pipe heat exchanger that may reach of having overcome the heat exchange of heat pipe booster effectively takes up room bigger, the shortcoming that cost is higher, can under the higher operating mode of flue-gas temperature, use, can carry out exchange heat with 3 kinds of different mediums, and can improve the service life of monoblock type heat exchanger.
2, simple in structure, difficulty of processing is little, the thermal efficiency is high, it is little to take up room, cost is low.
3, but there is the turbolator augmentation of heat transfer heat exchanger tube inside; Flue gas is walked outside the pipe, the dirt easy-clear.
