Description
Technical field
The utility model relates to a kind of shell and tube air preheater.
Background technology
At present, heat-pipe air preheater is widely used in the reheating furnace energy-saving equipment of industries such as oil, chemical industry, metallurgy.But the flue gas medium temperature that many operating modes are arranged is than higher, and 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; When temperature is low, be prone to cause the delay of internal working medium, 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 increase heat exchange area; If flue gas is serious to the corrosion and damage of tubulation, need to change integral device, then improved cost widely.
Summary of the invention
But the purpose of the utility model is to provide a kind of heat transfer efficiency height, long service life, safe and reliable, maintenance convenience, conserve space, the vertical tubulation air preheater of replace tubes formula that cost is low.The utility model mainly includes: heat exchanger tube, tube sheet, Shell Plate, air transition section assembly, flue gas and air import and export assembly.Wherein, The tubulation bundle that heat exchanger tube is made up of some tubulations preferably is provided with the turbolator of augmentation of heat transfer in the tubulation, this tubulation can be a light pipe; Preferably peripheral hardware is expanded the fin of heat-transfer surface, and this fin can be helical fin, fin, fin, H type fin and studded tube.Walked in the pipe by preheated air, high-temperature flue gas is walked outside the pipe.The above-mentioned heat exchanger tube two ends that are vertical state are located at respectively on the two horizontal tube sheets through hole corresponding with it, and promptly heat exchanger tube is provided with upper and lower two sealing rings with the position that two tube sheets are corresponding up and down, and preferably the sealing ring side face is provided with annular groove, is provided with sealing ring in the groove.Wherein, upper sealing ring is the annulus that top is provided with the extension seam, and this upper sealing ring places in the corresponding with it through hole of upper perforated plate, and seam is stuck on the upper perforated plate; Lower sealing ring is an annulus, and it can place in the corresponding with it circular groove of lower perforated plate.So heat exchanger tube two ends and upper and lower tube sheet are flexible connection, can not only satisfy the requirement of expanding with heat and contract with cold, and can change after the heat exchanger tube damage.Above-mentioned tube sheet dual-side links to each other with two vertical Shell Plate dual-sides respectively, is the heat exchanger tube chamber for the rectangular tubular casing of opening about formation.Above-mentioned heat exchanger tube chamber body one side opening links to each other with high-temperature flue gas import assembly one end, and the opposite side opening links to each other with high-temperature flue gas spout assembly one end, makes flue gas from a side direction opposite side bottom horizontal flow sheet.Above above-mentioned heat exchanger tube chamber body, be provided with the box-shaped air transition section assembly that the lower end links to each other with upper perforated plate, its side opening links to each other with the air outlet slit assembly.This air transition section assembly top board is a movable end cover, is used to change heat exchanger tube.Above-mentioned heat exchanger tube chamber body below is provided with the box-shaped side opening air intlet assembly that the upper end links to each other with lower perforated plate.Best, entire equipment is equipped with inner thermal insulating layer.
The utility model is when work; High-temperature flue gas carries out exchange heat with heat exchanger tube in the process that a side direction opposite side is advanced, be about to its heat that carries and pass to the air in the heat exchanger tube; So temperature raises behind the absorption of air heat in the entering heat exchanger tube, reaches the purpose with they preheatings; And high-temperature flue gas moves to outlet cooling back discharge from import.
The utility model compared with prior art has following advantage:
What 1, the utility model had overcome the heat exchange of heat pipe booster effectively possibly reach separated heat pipe heat exchanger big, the higher shortcoming of cost that takes up room; Can under the higher operating mode of flue-gas temperature, use; But heat exchange after heat exchanger tube damages, and the service life that can improve the 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, heat exchanger tube inside is provided with turbolator, but augmentation of heat transfer; Flue gas is walked outside the pipe, the dirt easy-clear.
