Below with reference to Fig. 1 description according to the steam generator 100 of the utility model embodiment.

As shown in Figure 1, including: that shell 10 and spiral pass according to the steam generator 100 of the utility model one embodiment Heat pipe.

Shell 10 limits the accommodating chamber of open upper end, and the wall surface of shell 10 is equipped with first entrance 8 and first outlet 9, the One entrance 8 and first outlet 9 are connected to accommodating chamber, hot heat transferring medium from first entrance 8 enter accommodating chamber, after heat exchange again from First outlet 9 flows out, for example heat transferring medium can be lead bismuth alloy coolant.

Spiral heat-transfer pipe is installed on accommodating chamber, and the upper end of spiral heat transfer duct occlusion accommodating chamber, spiral heat-transfer pipe and shell 10 are detachably connected, and the water inlet 1 of spiral heat-transfer pipe and steam (vapor) outlet 7 are set to upper end.

The tube body of spiral heat-transfer pipe is soaked in the heat transferring medium in accommodating chamber, and in course of normal operation, water is from top Water inlet 1 flows into spiral heat-transfer pipe, generates steam after the heat transferring medium heat exchange in the wall surface and accommodating chamber of spiral heat-transfer pipe, And it is discharged from the outlet on top.

Since the tube body of spiral heat-transfer pipe is soaked in the heat transferring medium in accommodating chamber, heat transferring medium can corrode spiral heat transfer Pipe is the steam generator 100 of lead bismuth alloy coolant especially for heat transferring medium, needs periodic inspection spiral heat-transfer pipe.

When needing to dismantle, the connection structure of spiral heat-transfer pipe and shell is unclamped, directly lifting spiral heat-transfer pipe can be real The separation of existing spiral heat-transfer pipe and shell, since the water inlet 1 and steam (vapor) outlet 7 of spiral heat-transfer pipe are set to upper end, water inlet 1 Do not interfere with the mounting and dismounting lines of spiral heat-transfer pipe (axis of steam generator 100) with steam (vapor) outlet 7, during installation passes spiral Heat pipe protrudes into accommodating chamber from top to bottom, is then fixedly connected with spiral heat-transfer pipe with shell.

According to the steam generator 100 of the utility model embodiment, by redesigning water inlet 1 and steam (vapor) outlet 7 The connection type of position and spiral heat-transfer pipe and shell can be realized the integral hoisting of spiral heat-transfer pipe, be easy to remove and repair.

As described in Figure 1, it is straight barrel type that shell, which is straight barrel type structure, especially accommodating chamber, and first entrance 8 can be set on outer The top of the side wall of shell and outwardly protruded from the lateral wall of shell, first outlet 9 can be set to the bottom of the side wall of shell and from The lateral wall of shell outwardly protrudes.Flow path in this way where heat transferring medium does not interfere the dismounting of spiral heat-transfer pipe.

As described in Figure 1, spiral heat-transfer pipe includes: that water inlet pipe 2, caching chamber and helix tube 5, the upper end of water inlet pipe 2 are formed Water inlet 1, caching chamber are set to lower end and are connected with the lower end of water inlet pipe 2, and the lower end of helix tube 5 is connected with caching chamber, spiral shell The upper end of coil 5 forms steam (vapor) outlet 7.

Water inlet pipe 2 includes: entrance 2a and main paragraph 2b, and the upper end of entrance 2a forms water inlet 1, entrance 2a from Top to bottm is tilted outward along the diameter of steam generator 100, and the upper end of main paragraph 2b is connected with the lower end of entrance 2a, main paragraph The lower end of 2b is connected with caching chamber, and main paragraph 2b is located at the center of helix tube 5.In other words, entrance 2a is tilting, Main paragraph 2b is vertical, and the axis of main paragraph 2b is overlapped with the central axes of helix tube 5, and such water inlet pipe 2 can play support The effect of helix tube 5.

The outer wall of helix tube 5 compresses the inner wall of shell, and inside and outside be able to achieve of such helix tube 5 is fixedly supported.

The sectional area of steam (vapor) outlet 7 is greater than the sectional area of water inlet 1, and water inlet 1 is offset to the side of connecting plate 6, is Steam (vapor) outlet 7 concedes bigger area.

As shown in Figure 1, spiral heat-transfer pipe includes connecting plate 6, connecting plate 6 and the upper end of shell 10 are detachably connected, into Water pipe 2 and helix tube 5 run through connecting plate 6.The top of shell is equipped with the flange flange turned down outward, and connecting plate 6 can be method Blue plate, connecting plate 6 are detachably connected with flange flange, for example connecting plate 6 is connected through a screw thread part with flange flange and is connected, When needing to overhaul spiral heat-transfer pipe, only need the threaded connector between dismantling connection plate 6 and flange flange that can sling spiral biography Heat pipe.

As shown in Figure 1, helix tube 5 is more helical structures, such as more helical structures, and multiple outlets of more helical structures are equal It is connected with steam (vapor) outlet 7, the heat transfer efficiency of more helical structures is higher, and higher steam generation rate may be implemented.

As shown in Figure 1, caching chamber be it is spherical, cache chamber top plate 4 be equipped be connected to the lower end of helix tube 5 lead to Hole, for double-stranded helix tube 5, top plate 4 is set there are two through-hole.The water that caching chamber can will be flowed into from water inlet 1 Distribute to helix tube 5.

In conclusion evaporation output efficiency is high, and can be square according to the steam generator 100 of the utility model embodiment Just maintenance is realized.

In the description of this specification, reference term " one embodiment ", " some embodiments ", " illustrative examples ", The description of " example ", " specific example " or " some examples " etc. means specific features described in conjunction with this embodiment or example, knot Structure, material or feature are contained at least one embodiment or example of the utility model.In the present specification, to above-mentioned art The schematic representation of language may not refer to the same embodiment or example.Moreover, description specific features, structure, material or Person's feature can be combined in any suitable manner in any one or more of the embodiments or examples.

While there has been shown and described that the embodiments of the present invention, it will be understood by those skilled in the art that: These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective And modification, the scope of the utility model are defined by the claims and their equivalents.
