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 that is 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 a kind of advanced person's warship boiler technology, with its advanced weight and size index and good mobility index.Because turbocharging unit utilizes flue gas acting, the exhaust gas temperature of supercharged steam generator device is higher, therefore, boiler efficiency is relatively low, sets up waste heat boiler and reclaim heat after supercharged steam generator device, both can increase the ability that supercharged steam generator supplies multi-parameter steam outward, improve the thermal efficiency of whole device, reduce oil consumption, improve endurance, can reduce infrared index again, improve the security on naval vessel.
Waste heat boiler is the horizontal heating surface forced circulation boiler of vertical flue.By flue gas flow direction, be furnished with successively evaporimeter and economizer.Each heating surface assembly of evaporimeter and economizer all adopts the two horizontal finned tube group of header forms, and pipe is staggered in arrangement.Heating surface is supported by tube sheet, and is assembled into bobbin carriage with flue.Bracing or strutting arrangement by arranging under bobbin carriage steel construction and bobbin carriage, is supported on waste heat boiler on basis.Drum is arranged in upper deck or independently on steel construction.Safety valve is set, Pressure gauge, water-level gauge, continuous blowdown interface on drum.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 position of waste heat boiler is the tube bank of being heated, and comprises evaporimeter tube bank and economizer tube bank two parts.
In the ships environment of ocean, there was dampness in the air, and common material easily corrodes.Naval vessel often waves, rocks in ocean, unstable, to having relatively high expectations of various device.Narrow space in ship power cabin, when waste heat boiler is installed, difficulty is larger.So need to design a kind of tube bank fixture of being heated that is applicable to supercharged steam generator waste heat recovery.At shipping high speed, travel or when wide-angle is turned, hull tilts larger, power-equipment also has larger inclination.Be heated after tube bank is tilted and be easily moved or collide with surrounding devices.While being heated tube bank design, considering and leave certain fit clearance with other equipment by expanded by heating, contact while preventing from expanding.At hull, wave, rock like this Shi Gengneng and cause heating surface wear.Header also needs special suspension member to fix as the gathering-device of heat transferring medium.
Due to what waste heat boiler peculiar to vessel had, be different from land waste heat boiler, be necessary to design a kind of tube bank fixture of being heated that is 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 that is applicable to supercharged steam generator waste heat recovery, there is the material that adapts to marine environment, when rocking, waving at hull, allowing the tube bank of being heated keep stable, there is not large movement, can also guarantee that tube bank has certain expansion space while being heated, allowing the tube bank of being heated work safely and reliably.
The object of the invention is to realize as follows: a kind of intensive tube bank fixture of being heated that is 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 angle steel link are with bolts, and angle steel link is welded on the steel channel beam of casing; On tube sheet and dividing plate, by the intensive conduit saddle of having arranged of the quantity of tube bank, conduit saddle adopts the structural design of little central angle, realized again the light feature of little quality that takes up room when having guaranteed 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 bank, water conservancy diversion flue gas; A plurality of headers have been designed to special header suspension member, after connection, be fixed on casing top; The header of bottom has designed header trustship, and header is carried in trustship to fixedly header; Total all adopts the resistant material that is applicable to marine ships environment.
The invention has the beneficial effects as follows: overall construction design is rationally exquisite, played the fixing and protective effect to the tube bank of being heated; Can guarantee the safe and stable operation of the intensive tube bank of being heated of waste heat boiler on ship.

the specific embodiment:
With reference to accompanying drawing, a kind of intensive tube bank fixture of being heated that is applicable to supercharged steam generator waste heat recovery.Structure forms and comprises the conduit saddle in tube sheet assembly, baffle assembly, header suspension member, header trustship.The intensive tube bank fixture of being heated that is applicable to supercharged steam generator waste heat recovery has the material that adapts to marine environment, when rocking, waving at hull, allowing the tube bank of being heated keep stable, there is not large movement, can also guarantee that tube bank has certain expansion space while being heated, allowing the tube bank of being heated work safely and reliably.
Tube bank is through tube sheet and dividing plate, on tube sheet and dividing plate by the intensive conduit saddle of having arranged of the quantity of tube bank.Conduit saddle has adopted the structural design of little central angle, has realized again the features such as little quality is light that take up room when having guaranteed tube bundle support.
Dividing plate is upper and lower with bolts with being connected of casing, has guaranteed the security after equipment expanded by heating.The present invention be for vertical exhaust-heat boiler designed, 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 bank, can also play the guide functions to flue gas, make flue gas can wash away more uniformly the tube bank of being heated.
A plurality of headers have been designed to special header suspension member, after connection, be fixed on casing top.The header of bottom has designed header trustship, and header is carried in trustship to fixedly header.Total all adopts the resistant material that is applicable to marine ships environment, and service life is longer.
Tube sheet and welding box body are fixed, and the intensive tube bank of being heated is through tube sheet, and tube sheet and conduit saddle support most of weight of tube bank, and tube bank is played to fixation.People Buddhism convenient for maintaining has been installed on tube sheet.
Fig. 1 median septum assembly 2 is bolted and is fixed in the middle of casing, can play Fixed Tube-sheet Reboiler and the evenly effect of flue gas.Dividing plate is bolted on angle beam, and angle beam is being welded on the steel channel beam of casing.Conduit saddle is arranged in dividing plate both sides, and the tube bank of being heated rides on conduit saddle through dividing plate.
Evaporator inlet-outlet header and economizer outlet header are fixed on casing top 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 placed in Fig. 1 in header trustship 4, and trustship is welded on casing.
