Description
Technical field:
The utility model relates to a kind of heat exchanger, particularly the heat pipe-type heat exchanger.
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, though heat-pipe air preheater has vertical and horizontal two kinds, but their primary structures are basic identical, be to establish the sagging plate that is fixed thereon in the frame bobbin carriage assembly, it is with bobbin carriage assembly separated into two parts, and a part is a smoke-box, another part is an air chamber, and the inlet tube and the outlet of fluid all established in each chamber.Heat pipe tube bank (light pipe or outer surface the are established fin) middle part of interior dress heat-transfer working medium is fixed on the through hole of sagging plate, and its part is positioned at smoke-box, and another part is positioned at air chamber.The two ends of heat pipe tube bank place respectively again on the end tube sheet, and this two ends tube sheet is separately fixed at again on the bobbin carriage plate of two chambers.Because the flue gas medium temperature of many operating modes is all than higher, for preventing the too high booster that takes place of heat pipe Yin Wendu, people once managed to reduce the heat exchange area that the heat pipe wall temperature promptly reduces fume side, adopt light pipe or strengthen the fin pitch as heat pipe, its weak point is, just need the volume of increase equipment if reach identical exchange capability of heat, thereby cause cost of investment to increase; Or adorn heat transfer medium temperature working medium in the front-seat heat pipe that contact earlier of employing and flue gas, and its weak point is, will cause the delay of inside heat pipe working medium when lower temperature, perhaps the pipe end heat-transfer working medium solidifies, and influences the Heat Transfer of Heat Pipe on Heat Pipe performance.
Summary of the invention:
The purpose of this utility model is to provide a kind of heat transfer efficiency height, long service life, high-temperature flue gas air preheater that cost is low.
The utility model mainly is to establish coupled turbolator heat exchanger before existing heat pipe air economizer bank smoke-box.This turbolator heat exchanger mainly includes shell, gripper shoe and turbolator tube bank.Wherein, (or inboard) end links to each other with the bobbin carriage plate of air heat tube preheater smoke-box front portion respectively under the two relative Shell Plates, goes up (or outside) end and links to each other with flue gas inlet tube.The in addition two ends of two Shell Plates link to each other with two gripper shoes respectively again and constitute square tube, i.e. turbolator pipe chamber, and this two gripper shoe following (or inboard) held and all linked to each other with the bobbin carriage plate of air heat tube preheater smoke-box front portion, and turbolator pipe chamber is connected with smoke-box; (or outside) end of going up of two gripper shoes links to each other with flue gas inlet tube.Above-mentioned two gripper shoes are orifice plate, and the two ends of turbolator pipe place in the through hole of these two gripper shoe correspondences respectively and are tightly connected.Be preferably in the turbolator pipe peripheral hardware fin and establish spoiler, to increase heat exchange area.An above-mentioned gripper shoe peripheral hardware air outlet slit pipe, another gripper shoe links to each other with an opening in air channel, and another opening in this box-shaped air channel links to each other with the bobbin carriage plate at air chamber rear portion.
Enter the air chamber of air heat exchange of heat pipe from the air intlet pipe when cold air, just with heat pipe bundle condensation segment in the vapour phase heat-transfer working medium carry out exchange heat, make it become fluid and flow to evaporator section, come out after the air channel enters in the turbolator tube bank from air chamber through the air after the heat exchange intensification, carry out exchange heat with the high-temperature flue gas that enters the flow-disturbing seed cell from flue gas inlet tube again, it is discharged from the air outlet slit pipe after absorbing heat again, and high-temperature flue gas enters smoke-box after cooling, liquid phase heat-transfer working medium in itself and the heat pipe beam evaporation section carries out exchange heat, make its evaporation become gas the heat-transfer working medium in the heat transferred heat pipe, then discharge through the flue gas after the cooling simultaneously from smoke outlet tube.
The utility model compared with prior art has following advantage:
1 the utility model can use under than higher operating mode in flue-gas temperature, because high-temperature flue gas is lowered the temperature through the turbolator heat exchanger before entering heat exchange of heat pipe, reduced the tube wall temperature of heat pipe beam evaporation section, so just, greatly reduce the possibility of heat pipe tube bank booster in heat exchange of heat pipe, the service life of having improved whole heat exchanger.
2 simple in structure, difficulty of processing is little, thermal efficiency height, cost are low.
3 dirt easy-clears.
