Description
Technical field:
The novel a kind of heat exchanger, particularly heat pipe-type heat exchanger of relating to of this reality.
Background technology:
At present, the drum heat pipe evaporator is widely used in the energy-saving equipment in fields such as oil, chemical industry and metallurgy partially, though there are vertical and horizontal two kinds, but their primary structure is basic identical, its smoke box has the square tube shape smoke box housing that is made of framework and bobbin carriage plate, and gas approach is established on the top of this housing, exhanst gas outlet is established in the bottom; Be provided with and its drum that links to each other side by side in above-mentioned smoke box housing one side, this drum is the cylinder that seals up and down, establishes saturated vapor water entrance pipe on it respectively; The heat pipe tube bank middle part of interior dress heat-transfer working medium is fixed on the drum, and a part is positioned at smoke box, and another part is positioned at drum.Its weak point is: when using under the operating mode that above-mentioned evaporimeter is less at flue gas flow, flue-gas temperature is higher, in order to reach certain heat transfer coefficient, certain flow velocity need be set, but the heat transfer area of single heat pipe tube bank is less, need more pipe row number, cause equipment not only thin but also long, bring bigger trouble for processing and manufacturing, transportation and on-the-spot the installation.
Summary of the invention:
The purpose of this utility model is to provide a kind of easy processing and manufacturing, be convenient to the two inclined to one side drum heat pipe evaporators of backhaul of single drum that transport, be convenient to install.The utility model mainly is to set up a vertical pass partition in the inclined to one side drum heat pipe evaporator of existing single drum list backhaul smoke box, and smoke box is become two backhauls by single backhaul, and in the junction of smoke box bottom two backhauls the sedimentation ash bucket is set.The two inclined to one side drum heat pipe evaporators of backhaul of a kind of single drum, its smoke box housing one side that is provided with smoke entrance is provided with and its drum that links to each other side by side, establish saturated vapor water entrance pipe on this drum respectively, the heat pipe tube bank middle part of interior dress heat-transfer working medium is fixed on the drum, a part is positioned at smoke box, another part is positioned at drum, it is characterized in that: in above-mentioned smoke box housing, establish a vertical clapboard, the top, two chambeies that is separated by dividing plate is established flue gas respectively and is advanced, outlet, the end socket that two chambeies are all contained is established in the bottom in above-mentioned two chambeies, and the heat pipe tube bank in the smoke box lays respectively in two chambeies of smoke box.The end socket of smoke box bottom is grey bucket type end socket.Boiler drum bottom is provided with blow-off pipe.
The utility model is basic identical with existing inclined to one side drum heat pipe evaporator structure, still mainly by smoke box, drum, heat pipe Shu Zucheng, just in the inclined to one side drum heat pipe evaporator of existing single drum list backhaul smoke box housing, set up a vertical pass partition, its two vertical limits can all link to each other with the smoke box housing, also can one another limit that links to each other with the smoke box housing, limit link to each other with drum.This pass partition is divided into two chambeies with the smoke box housing, and an adapter corresponding with it is respectively established on the top in these two chambeies, and one of them is taken over and is smoke outlet tube, and another is a flue gas inlet tube.An end socket that two chamber openings are all contained is established in the bottom in above-mentioned two chambeies, and two chambeies are connected.Preferably this end socket is bucket shape, and the opening of band valve is established in the lower end, and promptly grey bucket type end socket makes in the flue gas dust of sedimentation get rid of thus.Heat pipe tube bank in the above-mentioned smoke box, or pass through hole corresponding on the dividing plate by dividing plate separated into two parts or parallel with dividing plate by the dividing plate separated into two parts, above-mentioned this two parts heat pipe tube bank lays respectively in two chambeies of smoke box, form the two-stage heat-transfer surface, flue gas enters from flue gas inlet tube, through entering next backhaul heat exchange by bottom bulkhead after the backhaul heat exchange, to get rid of from smoke outlet tube again, original so not only thin but also long evaporimeter is by two backhaul heat exchange evaporimeters replacements of series connection side by side.Preferably boiler drum bottom is provided with blow-off pipe.
Enter the drum of evaporimeter from the carbonated drink inlet tube when saturation water, 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, discharge from the carbonated drink outlet at drum top through saturated vapor after the heat exchange and saturation water, and the liquid phase heat-transfer working medium in high-temperature flue gas 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, so circulation from smoke outlet tube.
The utility model compared with prior art has following advantage:
1, heat transfer efficiency height.
2, processing easily, transportation.
3, on-the-spot easy for installation.
4, can be from deashing, long service life.
