Technical field
The utility model relates to a kind of steam heater.
Background technology
While on coal-fired boiler in thermal power plant, the stove water in furnace wall cooling being heated, usual way is perforate and steam-heating pipe is installed on the water-cooling wall lower header, directly steam is introduced in header stove water is heated.The shortcoming of this kind mode is the larger vibrations of the large also initiation of noise that cause.
The utility model content
Technical problem to be solved in the utility model is: a kind of steam heater easy for installation is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of steam heater, comprise housing, be provided with heating chamber in housing, on housing, two ends are provided with liquid-inlet and liquid outlet, also be provided with steam inlet on housing, be provided with successively injector and blender along flow direction to be heated in described housing, injector interior is provided with the spray vapour chamber that is connected with described steam inlet, injector is provided with several and the nozzle that is communicated with of spray vapour chamber, blender be provided with some perforation blenders meet stream end and the other end hybrid chamber.
Large centre, described hybrid chamber two ends is little.
Described injector is tabular, and the stream end of meeting of described injector is provided with the tapered shunting boot segment of cross section.
Described blender is tabular, and described hybrid chamber is flat or circular cavity, and magnitude setting and position all corresponding with nozzle.
On described blender perpendicular to the fluid passage section of flow direction long-pending with injector on long-pending basic identical perpendicular to the fluid passage section of flow direction, described housing is cylindrical, and the two ends diameter is consistent with the pipe diameter of required connection, and the actual internal area that is heated fluid at described housing middle part is similar to actual internal area that the shell end that is connected with pipeline is heated fluid and adds on injector sectional area sum perpendicular to flow direction.
Described injector is provided with projection at nozzle location, and the projection inner surface is taper, and the projection top is provided with the aperture as nozzle.
Described housing is provided with steam input pipe in steam inlet.
The beneficial effects of the utility model are: this steam heater can be directly installed in water distribution pipe (as being arranged on the header water distribution pipe), avoided perforate on header, easy for installation, and can reduce noise and the vibrations in when heating, the uniformity of heating might as well simultaneously.
Description of drawings
Fig. 1 is that master of the present utility model looks the sectional structure schematic diagram.
Fig. 2 is that the A-A of Fig. 1 cuts open structural representation.
In Fig. 1 to Fig. 2: 1. housing, 2. heating chamber, 3. liquid-inlet, 4. liquid outlet, 5. steam input pipe, 6. injector, 61. spray vapour chambeies, 7. blender, 8. projection, 9. nozzle, 10. shunting boot segment, 11. hybrid chambers.
The specific embodiment
, below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1-2, a kind of steam heater, comprise housing 1, be provided with heating chamber 2 in housing 1, on housing 1, two ends are provided with liquid-inlet 3 and liquid outlet 4, also be provided with steam inlet and steam input pipe 5 on housing 1, described housing 1 is interior to be provided with successively the injector 6 that is tabular and to be tabular blender 7 along flow direction to be heated, injector 6 inside are provided with the spray vapour chamber that is connected with described steam inlet, described injector 6 is provided with two projections 8, projection 8 inner surfaces are taper, and projection 8 tops are provided with the aperture as nozzle 9.The stream end of meeting of injector 6 is provided with the tapered shunting boot segment 10 of cross section.Blender 7 be provided with all corresponding with the nozzle 9 perforation blender 7 in two positions meet stream end and the other end hybrid chamber 11, hybrid chamber 11 is that the large centre of flat cavity and two ends is little.On blender 7 perpendicular to basic identical perpendicular to the sectional area of flow direction on the sectional area of flow direction and injector 6, described housing 1 is cylindrical, and the two ends diameter is consistent with the pipe diameter of required connection, and the actual internal area that is heated fluid at described housing 1 middle part is similar to actual internal area that the shell end that is connected with pipeline is heated fluid and adds on injector 6 sectional area sum perpendicular to flow direction.
Be provided with successively injector 6 and blender 7 because housing 1 is interior along flow direction to be heated, injector 6 inside are provided with the spray vapour chamber 61 that is connected with described steam inlet, injector 6 is provided with several nozzles 9 that is communicated with spray vapour chamber 61, blender 7 be provided with some perforation blenders 7 meet stream end and the other end hybrid chamber 11, make liquid to be heated be entered blender 7 and thermally equivalent by the swiftly flowing steam absorption that nozzle 9 sprays, whole heater structure is simple, the manufacturing installation cost is low, heating effect is good, and during heating, noise is little.
, because injector 6 and blender 7 are tabular, reduced the flow resistance of liquid; And, because the stream end of meeting of injector 6 is provided with the tapered shunting boot segment 10 of cross section, the flow resistance of liquid and the impact own to injector 6 have further been reduced.
Because described hybrid chamber 11 is the flat cavity, can be in the situation that certain hybrid chamber 11 volumes that increase as much as possible of blender 7 sizes reach heating effect preferably; And magnitude setting and position are all corresponding with nozzle 9, make steam-energy that nozzle 9 ejects adsorb directly that current are laggard enters blender 7, have not only reduced the impact of blender 7 but also have made heating effect better.
Because housing 1 is cylindrical, and the two ends diameter is consistent with the pipe diameter of required connection, is convenient to same water distribution pipe connection is installed.
Due on described blender 7 perpendicular to basic identical perpendicular to the sectional area of flow direction on the sectional area of flow direction and injector 6, the actual internal area that is heated fluid at described housing 1 middle part is similar to actual internal area that the shell end that is connected with pipeline is heated fluid and adds on injector 6 sectional area sum perpendicular to flow direction, the unexpected variation of pressure and the flow velocity of current can be avoided causing due to the variation of circulation area, and then the instantaneous impact of current and noise can be avoided.The heater of this pattern only need to cut away water distribution pipe one section and then the heater welding upward be got final product while installing.The heater of this structure is specially adapted to the situation that thermal power generation unit coal-burning boiler do not design the stove hot-water heating system at first and undergoes technological transformation, and, owing to having avoided perforate on header, makes mounting process greatly simple and easy.
This steam heater, except applying on boiler, also can be used for other and can be directly installed in the occasion that on water distribution pipe, liquid is heated.
The present embodiment is only a kind of embodiment of this steam heater, but not conduct is to restriction of the present utility model, as long as in essential scope of the present utility model, the variation that those of ordinary skills do above-described embodiment all will drop in claims scope of the present utility model.
