Abstract
The utility model discloses a novel upward and downward heat pipe gas waste heat reclaiming device. The reclaiming device comprises a steam outlet pipe, a heat release section and a heated section. The steam outlet pipe is arranged at the upper end of a barrel, the lower end of the steam outlet pipe is communicated with a water pocket, and the lower part of the water pocket is communicated with a steam inlet pipe; a guide pipe is arranged in the center of the water pocket; the heated section is formed between the inner wall of the barrel and the outer ring of the water pocket, and the heat release section is formed between the inner wall of the barrel and the outer ring of the guide pipe; and fins are wound on a heat pipe section by section on the heat release section, and the area of the heat release section is controlled by the density of the fins. The reclaiming device prolongs the service life of the heat pipe by over two times, improves the overheated steam temperature, effectively prevents pipe blast caused by increased pressure in the pipe due to small heat release area of the heat pipe, quickly releases the heat of the heated section of the heat pipe at the heat release section, effectively prevents performance change of heat conducting liquid and drying of the heat pipe due to slow heat release of the heat pipe, improves the heat exchange efficiency and improves the utilization rate of materials.
Description
Technical field: the utility model relates to a kind of novel heat pipe up-downgoing coal gas waste-heat recoverer.
Background technology: in the production process of chemical industry synthetic ammonia, gas making workshop section heat pipe up-downgoing coal gas waste-heat recoverer, the heat pipe that the steam superheating section adopts is that heating section is a finned tube, heat release section is a light pipe.This kind design exists heat release section area problem less than normal in steam, coal gas or other gas converting heat, only way is that the number that increases heat pipe increases the heat release section area, and equipment volume is increased, and weight of equipment increases, cost up.Also exist heat pipe in addition and can produce incoagulable gas such as hydrogen in the course of the work, the meeting in service in to two year accumulates in the upper end of heat release section and the heat release section area is reduced, and heat exchange efficiency descends, and has shortened the service life of equipment greatly.
Summary of the invention: the purpose of this utility model is exactly that a kind of novel heat pipe up-downgoing coal gas waste-heat recoverer will be provided, and it can overcome the existing above problem of existing heat pipe up-downgoing coal gas waste-heat recoverer.The purpose of this utility model is to realize like this, novel heat pipe up-downgoing coal gas waste-heat recoverer, it comprises steam outlet pipe, heat release section, heating section, it is characterized in that: the upper end of cylindrical shell is provided with steam outlet pipe, the steam outlet pipe lower end communicates with Shui Bao, and water bag below communicates with the steam inlet pipe; Described Shui Bao outer ring upper and lower end is respectively by last bubble locating support, upward bubble analog bracket support; The central authorities of water bag are provided with mozzle; Inwall to Shui Bao outer ring is a heating section on the cylindrical shell, and water bag inwall to mozzle outer ring is a heat release section; Described heat release section is to carry out segmentation to twine fin on heat pipe, and the density degree by fin changes the area of controlling heat release section.The utility model has solved heat pipe short problem in service life effectively, makes from two to three years heat pipe life-spans of steam superheating section, has extended to more than 6 years.Improved superheat steam temperature, guaranteed that superheat steam temperature can also reach designing requirement after using 6 years.Effectively prevented because of heat pipe heat release section area is little, and made the pipe internal pressure increase the phenomenon of easy bombing.Make the heat of heat pipe heating section obtain quick release, effectively prevented to make the performance change of conductive fluid slowly and make heat pipe dry phenomenon occur because of heat pipe heat release speed in heat release section.Make the exchange heat of heating section and heat release section obtain balance, increased the Heat Transfer of Heat Pipe on Heat Pipe ability, improved heat exchange efficiency, improved the cost performance of stock utilization and equipment.
Description of drawings:
Fig. 1 is the utility model steam superheating segment structure schematic diagram;
8. descend the bubble locating support, 10. go up the bubble analog bracket, bubble sub-assembly on 11., bubble locating support on 12., 13. protective covers, 14. top board, 15. steam outlet pipes, 16. heat release section, 17. heating sections, 18. the steam inlet pipe, 19. water outlet pipes, 20. mozzles, 21. water bags.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
Novel heat pipe up-downgoing coal gas waste-heat recoverer, it comprises steam outlet pipe 15, heat release section 16, heating section 17, it is characterized in that: the upper end of cylindrical shell is provided with steam outlet pipe 15, and steam outlet pipe 15 lower ends communicate with water bag 21, and water bag 21 belows communicate with steam inlet pipe 18; Described water bag 21 outer ring upper and lower ends are respectively by last bubble locating support 12, upward bubble analog bracket 10 supports; The central authorities of water bag 21 are provided with mozzle 20; Inwall is a heating section 17 to water bag 21 outer rings on the cylindrical shell, and water bag 21 inwalls to mozzle 20 outer rings are heat release section 16; Described heat release section 16 is to carry out segmentation to twine fin on heat pipe, and the density degree by fin changes the area of controlling heat release section.During concrete enforcement, heat release section is suitably extended, increase heat exchange area by setting up radiating fin, increased several times than original light pipe area in heat release section.In the whole heat release part of heat pipe, to carry out segmentation and twine fin, the density degree by fin changes the area of controlling heat release section.
