Description
Technical field
The present invention relates to ship equipment technical field, refer in particular to a kind of intensive tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery.
Background technology
At present, steam power system is a kind of main Marine power plant, and supercharged steam generator is the main boiler on board technology of a kind of advanced person, with the weight and size index of its advanced person and good mobility index.Because gas-turbine driven supercharger utilizes flue gas to do work, the exhaust gas temperature of supercharged steam generator device is higher, therefore, boiler efficiency is relatively low, sets up waste heat boiler to reclaim heat after supercharged steam generator device, both the ability that supercharged steam generator supplies multi-parameter steam outward can have been increased, improve the thermal efficiency of whole device, reduce oil consumption, improve endurance, infrared index can be reduced again, improve the security on naval vessel.
Waste heat boiler is the horizontal heating surface forced circulation boiler of vertical flue.Evaporimeter and economizer is furnished with successively by flue gas flow direction.Evaporimeter and economizer each heating surface assembly all adopt two header horizontal finned tube group form, and pipe is staggered in arrangement.Heating surface by tube sheet support, and is assembled into bobbin carriage with flue.By the bracing or strutting arrangement arranged under bobbin carriage steel construction and bobbin carriage, waste heat boiler is supported on basis.Drum is arranged in upper deck or independently on steel construction.Drum arranges safety valve, Pressure gauge, water-level gauge, continuous blowdown interface.Drum is provided with suspension type manhole door.Boiler import and export flue is steel design, and insulating barrier is alumina silicate dry method needle punched blanket.The heat exchange part of waste heat boiler is tube bank of being heated, comprise evaporimeter tube bank and economizer restrain two parts.
In the ships environment of ocean, there was dampness in the air, and common material easily corrodes.Naval vessel often waves in ocean, rock, unstable, higher to the requirement of various equipment.Narrow space in ship power cabin, during installation waste heat boiler, difficulty is larger.So need to devise a kind of tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery.When shipping high speed travels or wide-angle is turned, hull tilts comparatively large, and power-equipment also has larger inclination.Be heated after tube bank is tilted and be easily moved or collide with surrounding devices.Be heated tube bundle designs time consider expanded by heating, leave certain fit clearance with other equipment, prevent expand time contact.Wave at hull like this, rock Shi Gengneng and cause heating surface wear.Header also needs special suspension member to fix as the gathering-device of heat transferring medium.
What have due to marine heat recovery boiler is different from land waste heat boiler, is necessary to design a kind of tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery.
Summary of the invention
The object of this invention is to provide a kind of intensive tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery, there is the material adapting to marine environment, rock at hull, allow when waving tube bank of being heated keep stable, there is not large movement, can also ensure to restrain when being heated and there is certain expansion space, allowing be heated tube bank work safely and reliably.
The object of the invention is to realize as follows: a kind of intensive tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery, mainly comprise the conduit saddle in tube sheet assembly, baffle assembly, header suspension member, header trustship, it is characterized in that: the tube bank in invention is through tube sheet and dividing plate, the structure of baffle assembly comprises angle iron connecting piece, conduit saddle, conduit saddle is welded on dividing plate plate body, tube bank is passed from dividing plate, dividing plate and Bolted angle connection frame with bolts, Bolted angle connection frame is welded on the steel channel beam of casing; By the intensive conduit saddle arranged of quantity of tube bank on tube sheet and dividing plate, conduit saddle adopts the structural design of little central angle, ensure that achieving again the light feature of little quality that takes up room while tube bundle support; Baffle arrangement direction is parallel with sweep of gases direction, and dividing plate is placed on the centre position of heating surface, supports intensive tube bundle, water conservancy diversion flue gas; Special header suspension member is devised to multiple header, after connection, is fixed on casing top; The header of bottom devises header trustship, header is mounted in fixing header in trustship; Total all adopts the resistant material of applicable marine vessel environment.
The invention has the beneficial effects as follows: overall construction design is rationally exquisite, serve the fixing of tube bank of being heated and protective effect; The safe and stable operation of the intensive tube bank of being heated of waste heat boiler on ship can be ensured.

detailed description of the invention:
With reference to accompanying drawing, a kind of intensive tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery.Structure forms the conduit saddle comprised in tube sheet assembly, baffle assembly, header suspension member, header trustship.The intensive tube bank fixture of being heated being applicable to supercharged steam generator waste heat recovery has the material adapting to marine environment, rock at hull, allow when waving tube bank of being heated keep stable, there is not large movement, can also ensure to restrain when being heated and there is certain expansion space, allowing be heated tube bank work safely and reliably.
Restrain through tube sheet and dividing plate, by intensive first conduit saddle arranged of quantity of tube bank on tube sheet and dividing plate.First conduit saddle have employed the structural design of little central angle, ensure that and achieves again to while tube bundle support the features such as little quality is light that take up room.
Dividing plate connection that is upper and lower and casing is with bolts, ensure that the security after equipment expanded by heating.The present invention is designed by vertical exhaust-heat boiler, baffle arrangement direction is parallel with sweep of gases direction, and dividing plate is placed on the centre position of heating surface, can be good at supporting intensive tube bundle, the guide functions to flue gas can also be played, make flue gas can evenly wash away tube bank of being heated.
Special header suspension member is devised to multiple header, after connection, is fixed on casing top.The header of bottom devises header trustship, header is mounted in fixing header in trustship.Total all adopts the resistant material of applicable marine vessel environment, and service life is longer.
Tube sheet and welding box body are fixed, and intensive tube bank of being heated is through tube sheet, and tube sheet and conduit saddle support most of weight of tube bank, and play fixation to tube bank.Tube sheet is installed people Buddhism convenient for maintaining.
Fig. 1 median septum assembly 2 is bolted and is fixed in the middle of casing, can play the effect of Fixed Tube-sheet Reboiler and even flue gas.Dividing plate is bolted on angle beam, and angle beam is on the steel channel beam being welded to casing.Conduit saddle is arranged in dividing plate both sides, and tube bank of being heated rides on conduit saddle through dividing plate.
Evaporator inlet-outlet header and economizer outlet header are fixed on above casing by header suspension member 3 in Fig. 1.Header position is in the middle of heat-insulation layer, and insulation filling materials also plays fixation to header.
Economizer inlet header is taken and is put in header trustship 4 in FIG, and trustship is welded on casing.
