Description
technical field:
The present invention relates to ship equipment technical field, refer in particular to a kind of modularization heat exchange casing that is applicable to waste heat boiler peculiar to vessel.
background technology:
At present, the boats and ships of supercharged steam generator power and Gas Turbine Power can carry out recovered flue gas with waste heat boiler peculiar to vessel.The gas power system that is main body with steam power system and the gas turbine of supercharged steam generator device is two kinds of important motivity systems on naval vessel.Two kinds of dynamical systems have advantages of separately, but the exhaust gas temperature of two kinds of dynamical systems is all higher, have so just caused the waste of the energy, especially, in the limited situation of ship loading fuel quantity, have affected the flying power of boats and ships.With waste heat boiler, reclaim the high-temperature flue gas that ship power system is discharged, can improve the utilization rate of fuel, saved the energy, the energy of re-using can be used for increasing life on power and ship.So waste heat boiler has very large using value in Marine power plant.
Waste heat boiler channel structure is the main heating surface of waste heat boiler, is the heat exchange place of flue gas and waste heat boiler working medium.The structure and characteristics of bobbin carriage has determined the Some features of whole waste heat boiler.Limited space in boats and ships, the compact designed so the equipment in dynamical system also should be tried one's best, reserves more space and meets the functional of ship.In limited space, complete a certain amount of flue gas heat exchange, just need the tube bank of type compact to design to arrange, in the confined space, arrange the tube bank satisfying the demands, helical fin tube bank that should efficient heat transfer.
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.So need to design a kind of waste heat boiler channel structure that is applicable to ship environment.This structure can reclaim the smoke evacuation of supercharged steam generator and design.When needs reclaim other parameter flue gas heat, can realize by adjusting casing design size and heating surface quantity.In ship environment, heat exchange box body structure can reclaim the flue gas of the smoke evacuation of supercharged steam generator device and gas turbine smoke evacuation and other parameters.
Narrow space in ship power cabin, when waste heat boiler is installed, difficulty is larger.If design the installation period that channel structure that a kind of modularization can integral installation can shorten waste heat boiler peculiar to vessel.So need to design a kind of modularization heat exchange box body structure that is applicable to waste heat boiler peculiar to vessel, very compact being applicable in space limited in ship environment of heated face structure design, heat exchange box body structure be modularized design can factory in processing and manufacturing then whole Transporting to on-the-spot, integral installation, installation period is extremely short.
Due to what waste heat boiler peculiar to vessel had, be different from land waste heat boiler, be necessary to design a kind of be applicable to waste heat boiler peculiar to vessel can modularization integral installation the heat exchange box body structure of efficient heat transfer.
summary of the invention:
The object of this invention is to provide a kind of modularization heat exchange casing that is applicable to waste heat boiler peculiar to vessel, overcome existing land waste heat boiler and can not be applied to the deficiency in marine ships.
The object of the invention is to realize as follows: a kind of modularization heat exchange casing that is applicable to waste heat boiler peculiar to vessel, mainly comprise evaporimeter, economizer, header, insulation construction, body structure, it is characterized in that: the import and export of economizer are connected with drum with feed pipe respectively, evaporimeter is connected with drum.
Heat exchange box body structure is to design in order to reclaim the smoke evacuation of supercharged steam generator, and recovered flue gas parameter is: flue gas volume flow 115KNm
3/ h, 405 ℃ of flue-gas temperatures.
On body structure, with the heating surface of efficient, compact heat exchange, heat exchange box body structure is modularized design.
Total all adopts the resistant material that is applicable to marine ships environment.
The invention has the beneficial effects as follows: there is the material that adapts to marine environment, tube bank that can efficient heat transfer, it is little that compact conformation takies on ship space, adopts the modularized design can integral body integral installation at the scene after processing in factory.

the specific embodiment:
With reference to accompanying drawing, a kind of modularization heat exchange box body structure that is applicable to waste heat boiler peculiar to vessel, this structure comprises evaporimeter, economizer, header, insulation construction, body structure.Heat exchange box body structure is a kind of heat-exchanger rig peculiar to vessel, is the chief component of waste heat boiler heating surface peculiar to vessel.The import and export of economizer are connected with drum with feed pipe respectively, and during sweep of gases economizer, economizer converts the heat of feedwater to from smoke absorption heat.Evaporimeter is connected with drum, during sweep of gases evaporimeter, converts cigarette temperature to vapor (steam) temperature.Insulation construction reduces smoke spillage, reduces radiation loss.Body structure is for integrated support and the inner heating surface of protection.Heat exchange box body structure is to design in order to reclaim the smoke evacuation of supercharged steam generator, and recovered flue gas parameter is: flue gas volume flow 115KNm
3/ h, 405 ℃ of flue-gas temperatures.When needs reclaim other parameter flue gas heat, can realize by adjusting casing design size and heating surface quantity.In ship environment, heat exchange box body structure can reclaim the flue gas of the smoke evacuation of supercharged steam generator device and gas turbine smoke evacuation and other parameters.This structure is with the heating surface of high efficient heat exchanging, and heated face structure designs very compact being applicable in space limited in ship environment.Heat exchange box body structure be modularized design can factory in processing and manufacturing then whole Transporting to on-the-spot, integral installation, installation period is extremely short.Total all adopts the resistant material that is applicable to marine ships environment, and service life is longer.
With reference to Fig. 1, the modularization heat exchange box body structure top that is applicable to waste heat boiler peculiar to vessel is connected with the gas approach of waste heat boiler, and flue gas enters casing from top, and flue gas successively washes away evaporimeter 1, economizer 2.In casing, carry out heat exchange with boiler feedwater, the boiler feedwater in heating economizer, the saturation water in heating fumigators, saturation water becomes saturated vapor through heating.In boiler, feedwater enters economizer from economizer entrance header, after heat exchange, by economizer outlet header, enter in waste heat boiler drum, from drum, by pipeline, enter evaporimeter again and carry out heat exchange, with the form inflow waste heat boiler drum of steam, by drum, supply with extraneous use.
With reference to Fig. 1, in casing, tube sheet 4 is welded on cabinet shell steel plate.Dividing plate 5 is bolted on the steel channel beam that is fixed on casing top.Evaporimeter and economizer tube bank are fixed in casing through tube sheet and dividing plate.
With reference to Fig. 2,3, heat-insulation layer 3 in blank map 2 between outer casing 3 in tube sheet and Fig. 3, reduces the radiation loss of high-temperature flue gas.
With reference to Fig. 1,3, the outer surface of casing is outer casing 3 in Fig. 3, and angle steel support 2 and H type steel support 1 in Fig. 3 have been welded in outer casing outside.Outer casing inner side is heat-insulation layer, and heat-insulation layer inner casing 1 in Fig. 4 is fixing.In casing when maintenance, can be opened in Fig. 1 manhole door 6 and be entered casing and overhaul.
After casing has been assembled, whole Transporting is connected with other parts of waste heat boiler to on-the-spot, forms waste heat boiler.
