Alternatively, water inlet 13 may be provided in any position of the roof (such as lid 16) of the housing 1 corresponding with exocoel 11.

According to embodiments more of the present utility model, with reference to shown in Fig. 4, Fig. 8-Figure 10 and Figure 12-Figure 13, holding dirt structure is at least one in mesh grille 41, strip grid 42 and column grid 43.

Such as, as shown in Figure 4, holding dirt structure is mesh grille 41, thus it is not only advantageous to the surface area increased in housing 1, so that more incrustation scale is attached on mesh grille 41, improve the service life of steam generator 100 to a certain extent, and the mesh on mesh grille 41 also can stop the incrustation scale flowing with water vapour, to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14, the setting of mesh grille 41 simultaneously also avoid the setting of steam (vapor) outlet 14 place drainage screen, make incrustation scale be attached to the steam (vapor) outlet 14 caused on drainage screen thus avoiding in prior art and block because arranging drainage screen at steam (vapor) outlet 14 place and under the impact of water vapour, flow on the exterior line connected with steam (vapor) outlet 14 problems such as the blocking of the pipeline caused because of the incrustation scale on drainage screen.

It should be noted that the mesh of mesh grille 41 can be formed as circular port or hexagonal hole or other shapes of hole, this is not construed as limiting by this utility model. It is understood that the size of the multiple mesh on mesh grille 41 can be identical, naturally it is also possible to be different. Alternatively, the size of the mesh on mesh grille 41 is adjustable. For example, it is possible to the difference according to the water quality in each area and operating mode, regulate the size of mesh on mesh grille 41.

Alternatively, mesh grille 41 can include multiple, and multiple mesh grille 41 interval in residing chamber (i.e. exocoel 11 and/or inner cavity chamber 12) is arranged. Such as shown in Figure 4, three mesh grille 41 intervals are located in exocoel 11, thus increasing the bond area of incrustation scale to a greater degree, but also can stop that the incrustation scale flowing with water vapour is to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14 to a greater degree.

Such as, as shown in Figure 12-Figure 13, holding dirt structure is strip grid 42, thus it is not only advantageous to the surface area increased in housing 1, so that more incrustation scale is attached on strip grid 42, improve the service life of steam generator 100 to a certain extent, but also the incrustation scale flowing with water vapour can be stopped, to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14, the setting of strip grid 42 simultaneously also avoid the setting of steam (vapor) outlet 14 place drainage screen, make incrustation scale be attached to the steam (vapor) outlet 14 caused on drainage screen thus avoiding in prior art and block because arranging drainage screen at steam (vapor) outlet 14 place and under the impact of water vapour, flow on the exterior line connected with steam (vapor) outlet 14 problems such as the blocking of the pipeline caused because of the incrustation scale on drainage screen. additionally, owing to each grate opening of strip grid 42 extends in the short transverse of strip grid 42, therefore after strip grid 42 stops incrustation scale, incrustation scale can be deposited on downwards the bottom of strip grid 42 under gravity, thus reducing the probability that strip grid 42 is blocked by incrustation scale, it is ensured that the area of passage of water vapour on strip grid 42, and then make water vapour when flowing through strip grid 42, its flow velocity is unlikely to excessive, it is to avoid incrustation scale goes out steam (vapor) outlet 14 with water vapour.

It is understood that the size of grate opening and number are adjustable on each strip grid 42, for instance, it is possible to the difference according to the water quality in each area and operating mode, regulate the size of grate opening.

Alternatively, strip grid 42 can include multiple, and multiple strip grid 42 interval in residing chamber (i.e. exocoel 11 and/or inner cavity chamber 12) is arranged. Such as shown in figure 13, three strip grid 42 intervals are located in exocoel 11, thus to a greater degree increase incrustation scale can bond area, but also can stop to a greater degree incrustation scale with water vapour flowing to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14.

Further, mesh grille 41 and/or strip grid 42 are located in exocoel 11, and the two ends of mesh grille 41 and/or the two ends of strip grid 42 are connected with the lateral wall of the medial wall of exocoel 11 and partition wall 2 respectively. Such as, when only arranging mesh grille 41 in exocoel 11, the two ends of mesh grille 41 are connected with the lateral wall of the medial wall of exocoel 11 and partition wall 2 respectively, when only arranging strip grid 42 in exocoel 11, the two ends of strip grid 42 are connected with the lateral wall of the medial wall of exocoel 11 and partition wall 2 respectively, when being simultaneously provided with strip grid 42 and mesh grille 41 in exocoel 11, strip grid 42 and the respective two ends of mesh grille 41 are connected with the lateral wall of the medial wall of exocoel 11 and partition wall 2 respectively. Thus, not only can play the effect of fixing mesh grille 41 and/or strip grid 42, also the water vapour that can pass through in exocoel 11 has to pass through mesh grille 41 and/or strip grid 42 could continue flow forward, thus reliably stopping the incrustation scale flowing with water vapour.

Specifically, with reference to Fig. 5, the medial wall of exocoel 11 and the lateral wall of partition wall 2 are respectively formed with the first draw-in groove 111 and the second draw-in groove 22, the two ends of mesh grille 41 and/or the two ends of strip grid 42 are fastened in the first draw-in groove 111 and the second draw-in groove 22 respectively, thus, can mesh grille 41 and/or strip grid 42 be securely fixed in exocoel 11, avoid because mesh grille 41 and/or the fixing loosely mesh grille 41 caused and/or strip grid 42 movement or rock the result of use affecting mesh grille 41 and/or strip grid 42 exocoel 11 in of strip grid 42.

Such as, in the concrete example of Fig. 5, first buckle slot and the second draw-in groove 22 are all in the upper extension of the short transverse (i.e. the short transverse of partition wall 2) of housing 1, thus strip grid 42 and/or mesh grille 41 being securely fixed between exocoel 11 and partition wall 2. Specifically, the first draw-in groove 111 is to be protruded the medial walls of exocoels 11 by two and the first prominent muscle of being spaced apart from each other limits. Second draw-in groove 22 is to be protruded the lateral walls of partition walls 2 by two and the second prominent muscle of being spaced apart from each other limits, simple and reliable for structure. Alternatively, second highlight between muscle and partition wall 2 and the first prominent part that can be formed in one between muscle and housing 1.

Thus it is not only advantageous to the surface area increased in exocoel 11 and/or inner cavity chamber 12, so that more incrustation scale is attached on extension bar 431, also can improve the service life of steam generator 100 to a certain extent, and the setting extending bar 431 also can stop the incrustation scale flowing with water vapour to a certain extent, to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14.

Specifically, the multi-turn that column grid 43 includes along the short transverse of housing 1 is distributed extends bar 431, often circle extend bar 431 include circumferentially distributed (such as, circumferentially distributed along partition wall 2) multiple, such that it is able to body increases the surface area in exocoel 11 and/or inner cavity chamber 12 more, so that holding more incrustation scale, also helping simultaneously and stopping the incrustation scale flowing with water vapour largely, to improve the service life of steam generator 100. Further, adjacent two circles extend that bar 431 is interlaced with each other in the height direction to be opened, for instance, in housing 1 short transverse, the multi-turn of distribution extends bar 431 and offsets one from another. Thus, when incrustation scale is with mathematical models, incrustation scale can be increased to a greater degree and encounter the probability extending bar 431, thus stopping the incrustation scale flowing with water vapour, the blocking of pipeline that the steam (vapor) outlet 14 caused to avoid incrustation scale to go out steam (vapor) outlet 14 with water vapour further blocks or is connected with steam (vapor) outlet 14, thus improving the service life of steam generator 100.

Alternatively, extend bar 431 to extend from the lateral wall and/or medial wall of partition wall 2, such as, when column grid 43 is located in inner cavity chamber 12, extend bar 431 then to extend from the medial wall of partition wall 2 to inner cavity chamber 12, when column grid 43 is located in exocoel 11, extend bar 431 then to extend from the lateral wall of partition wall 2 to exocoel 11, when being located at when column grid 43 in exocoel 11 and inner cavity chamber 12, multiple extension bars 431 extend and extend in inner cavity chamber 12 in exocoel 11 from lateral wall and the medial wall of partition wall 2 respectively simultaneously.
