The specific embodiment

Present embodiment provides a kind of marine vapor heater that utilizes steam to realize air heat.As illustrated in fig. 1 and 2, the marine vapor heater comprises air inlet pipe 1, drain pipe 2, heat exchange main body 3, fixed mount, suction flange 5 and outlet(discharge) flange 6.Wherein:

Air inlet pipe 1 and drain pipe 2 lay respectively at two sides up and down of heat exchange main body 3, and heat exchange main body 3 comprises that a plurality of copper wing corrugated plate 30 vertically arranged passes the heat exchanger tube 31 that a plurality of wing corrugated plates 30 settings and upper and lower end parts are connected with air inlet pipe 1 and drain pipe 2 respectively with vertical.A plurality of wing corrugated plate 30 is fixed through fixed mount.

Inlet end place side with air inlet pipe 1 is the front side, and fixed mount comprises upper perforated plate 40 and lower perforated plate 41 that is positioned at a plurality of wing corrugated plates both sides about in the of 30 and the front tube sheet 42 and back tube sheet 43 that is positioned at both sides, a plurality of wing corrugated plates 30 front and back.The front and back side of upper perforated plate 40 and lower perforated plate 41 is connected with the upper and lower side of front tube sheet 42 with back tube sheet 43 through fixed connecting piece 7 (set bolt) respectively, and the front and back side of said wing corrugated plate 30 is connected with back tube sheet 43 with front tube sheet 42 respectively.

In addition, exhaust needle-valve 11 is installed on air inlet pipe 1, discharge opeing needle-valve 21 is installed on drain pipe 2.

Take the method for using and the characteristics of marine vapor heater of said structure following:

1, the marine vapor heater links to each other with extraneous boiler or steam generator through suction flange; In use; Open the valve of suction flange 5 outsides; High-temperature steam gets in the heat exchanger tube 31 through air inlet pipe 1, and wind is crossed wing corrugated plate 30 and carried out heat exchange with heat exchanger tube 31 interior steam, thereby improves wind pushing temperature.High-temperature steam is through after the heat exchange, and the temperature reduction is connected into water with fixed attention, is discharged to the equipment outside through drain pipe 2.When stopping using equipment, can open exhaust needle-valve 11 and discharge residual steam in the heater, open discharge opeing needle-valve 21, discharge condensate.
