Further, the electrical terminal 31 of heating element heater 3 embeds in barrier rib 5 and by the perforating exposed on the sidewall of the housing 1 corresponding with barrier rib 5.Specifically, owing to barrier rib 5 is one-body molded with housing 1 and partition wall 2, the electrical terminal 31 of the heating element heater 3 being located on partition wall 2 embeds and arranges barrier rib 5, and offers perforation at housing 1 sidewall of barrier rib 5 correspondence position, and electrical terminal 31 also is used for electrically connecting through perforating exposed.Thus, in the ingenious embedding barrier rib 5 of terminals of heating element heater 3, not only simple in construction, and avoid electric wire layout complicated in housing 1.

Alternatively, housing 1 and the partition wall 2 being formed in housing 1, barrier rib 5 can be all aluminum casting.

Further, water inlet 13 is positioned at the side deviating from connectivity slot 21 of barrier rib 5, say, that water inlet 13 and connectivity slot 21 lay respectively at the both sides of barrier rib 5.Thus, as shown in figure 15, flow into the water in exocoel 11 from water inlet 13 under the heat effect of heating element heater 3, be vaporized into the water vapour that aridity is little, owing to barrier rib 5 acts on the one week arrival connectivity slot 21 making water vapour along exocoel 11 and the periphery wall around partition wall 2, and enter in inner cavity chamber 12 by connectivity slot 21, when water vapour again heated and drying after entering inner cavity chamber 12, further the steam that Steam Reforming is dry is discharged from steam (vapor) outlet 14.In the process, add the contact area of water vapour and partition wall 2 surfaces externally and internally and housing 1 inner surface, avoid the heating element heater 3 being located on partition wall 2 that the phenomenon of hot-spot occurs, be conducive to improving the service life of partition wall 2 and heating element heater 3, and improve the efficiency of heating surface of heating element heater 3, further reduce the preheating time of steam generator 100 simultaneously, also advantageously improve the aridity of steam.

Specifically, steam generator 100 includes the first water inlet pipe 61 connected with water inlet 13, and the water side of the first water inlet pipe 61 is stretched in exocoel 11.Such as, as shown in figure 15, the water side of the first water inlet pipe 61 extends downwardly in exocoel 11.Thus, the water side of the first water inlet pipe 61 and connectivity slot 21 lay respectively at the both sides of barrier rib 5, the water flowed out from the water side of the first water inlet pipe 61 circulates in exocoel 11, and become the less water vapour of mass dryness fraction through heating element heater 3 heating needs the connectivity slot 21 that could pass through for a week around partition wall 2 to enter in inner cavity chamber 12 simultaneously.In the process, add the contact area of water vapour and partition wall 2 surfaces externally and internally and housing 1 inner surface, avoid the heating element heater 3 being located on partition wall 2 that the phenomenon of hot-spot occurs, be conducive to improving the service life of partition wall 2 and heating element heater 3, and improve the efficiency of heating surface of heating element heater 3, further reduce the preheating time of steam generator 100 simultaneously, also advantageously improve the aridity of steam.

In other embodiments of the present invention, water inlet 13 is positioned at the identical side of barrier rib 5 with connectivity slot 21.

Specifically, as shown in Fig. 8 and Figure 11-Figure 12, steam generator 100 includes the second water inlet pipe 62 connected with water inlet 13, and the free end of the second water inlet pipe 62 extends to the opposite side of barrier rib 5 from the side of the close connectivity slot 21 of barrier rib 5 around the circumferential direction of partition wall 2.Thus, enter into after the water in exocoel 11 becomes water vapour under the heating of heating element heater 3 from the second water inlet pipe 62, at least part of water vapour needs within one week of the circumferential direction around partition wall 2, to pass through connectivity slot 21 in exocoel 11 and enters in inner cavity chamber 12, in the process, add the contact area of water vapour and partition wall 2 surfaces externally and internally and housing 1 inner surface, avoid the heating element heater 3 being located on partition wall 2 that the phenomenon of hot-spot occurs, be conducive to improving the service life of partition wall 2 and heating element heater 3, and improve the efficiency of heating surface of heating element heater 3, further reduce the preheating time of steam generator 100 simultaneously, also advantageously improve the aridity of steam.

Certainly, the invention is not restricted to this, water inlet pipe may be formed as other shape, for instance, the water inlet end of water inlet pipe connects with water inlet 13, and the other end of water inlet pipe is repeatedly arranged around the circumferential direction of partition wall 2.Or, the other end of water inlet pipe can also be spirally wound in the circumferential direction of partition wall 2.

Alternatively, as shown in Figure 8, second water inlet pipe 62 has multiple spaced first apopore 621, thus, the water flowed out from multiple first apopores 621 can be injected in the periphery wall of partition wall 2, thus forming current or moisture film on the periphery wall of partition wall 2, and current or moisture film flow downward along the periphery wall of partition wall 2, so that abundant heat exchange between aqueous water and heating element heater 3, and the water vapour produced from the water away from the first apopore 621 ejection of connectivity slot 21 of the second water inlet pipe 62 needs the connectivity slot 21 that could pass through for a week around the periphery wall of partition wall 2 to enter in inner cavity chamber 12, thus being conducive to improving the efficiency of heating surface of heating element heater 3, reduce the preheating time of steam generator 100, can also avoid heating element heater 3 that the phenomenon of hot-spot occurs simultaneously, be conducive to extending the service life of heating element heater 3.Alternatively, multiple first apopores 621 are evenly spaced apart to be located at the side of the close partition wall 2 of the second water inlet pipe 62, consequently facilitating the water that the first apopore 621 flows out is injected on partition wall 2 so that the heating of heating element heater 3 as much as possible.It is understood that when multiple first apopores 621 on the second water inlet pipe 62 are very little and eject vaporific little water droplet, above-mentioned advantage can be made to be optimized further.

In other concrete examples of the present invention, the free end of the second water inlet pipe 62 is water side, thus, water side and the connectivity slot 21 of the second water inlet pipe 62 are spaced apart by barrier rib 5, after the water flowed out from the water side of the second water inlet pipe 62 becomes water vapour under the heating of heating element heater 3, the connectivity slot 21 that could pass through for one week around the periphery wall of partition wall 2 is needed to enter in inner cavity chamber 12, in the process, add the contact area of water vapour and partition wall 2 surfaces externally and internally and housing 1 inner surface, avoid the heating element heater 3 being located on partition wall 2 that the phenomenon of hot-spot occurs, be conducive to improving the service life of partition wall 2 and heating element heater 3, and improve the efficiency of heating surface of heating element heater 3, further reduce the preheating time of steam generator 100 simultaneously, also advantageously improve the aridity of steam.

Specifically, as shown in Figure 8 and Figure 11, the second water inlet pipe 62 includes C-shaped pipes section 622 and is perpendicular to C-shaped pipes section 622 and the vertical pipeline section 623 being connected with water inlet 13, simple in construction.Further, second water inlet pipe 62 is looped around the outside in the external wall of upper portion face of partition wall 2, thus, the outside in the external wall of upper portion face of partition wall 2 can be sprayed at from least some of water of the second water inlet pipe 62 discharge, and flow downward along partition wall 2, thus being conducive to heat exchange abundant with heating element heater 3, improving the efficiency of heating surface of heating element heater 3, also avoiding heating element heater 3 to a certain extent there is the phenomenon of hot-spot simultaneously.Certainly, the invention is not restricted to this, the second water inlet pipe 62 can also surround other position in partition wall 2 short transverse, for instance the second water inlet pipe 62 is looped around the outside of the middle part outside wall surface of partition wall 2 or the outside of bottom outside wall surface.

In other concrete examples of the present invention, the 3rd water inlet pipe that steam generator 100 also includes connecting with water inlet 13 (not shown go out), the water side of the 3rd water inlet pipe extend into the side away from connectivity slot 21 of exocoel 11 through barrier rib 5, so that the water side of the 3rd water inlet pipe and connectivity slot 21 lay respectively at the both sides of barrier rib 5, so that after the water that the water side of the 3rd water inlet pipe is flowed out enters in exocoel 11 and become water vapour under the heating of heating element heater 3, at least part of water vapour needs within one week of the circumferential direction around partition wall 2, to pass through connectivity slot 21 in exocoel 11 and enters in inner cavity chamber 12, in the process, add the contact area of water vapour and partition wall 2 surfaces externally and internally and housing 1 inner surface, avoid the heating element heater 3 being located on partition wall 2 that the phenomenon of hot-spot occurs, be conducive to improving the service life of partition wall 2 and heating element heater 3, and improve the efficiency of heating surface of heating element heater 3, further reduce the preheating time of steam generator 100 simultaneously, also advantageously improve the aridity of steam.

Further, the 4th water inlet pipe that steam generator 100 also includes connecting with water inlet 13 (not shown go out), the free end of the 4th water inlet pipe is closed and the 4th water inlet pipe traverse barrier rib 5, and extend along the circumferential direction of partition wall 2, the length direction of the 4th water inlet pipe is formed multiple spaced second apopore (not shown go out), thus, the water flowed out from multiple second apopores can be injected in the periphery wall of partition wall 2, thus forming current or moisture film on the periphery wall of partition wall 2, and current or moisture film flow downward along the periphery wall of partition wall 2, so that aqueous water and the abundant heat exchange of heating element heater 3, and the water vapour produced from the water away from the second apopore ejection of connectivity slot 21 of the 4th water inlet pipe needs the connectivity slot 21 that could pass through for a week around the periphery wall of partition wall 2 to enter in inner cavity chamber 12, thus being conducive to improving the efficiency of heating surface of heating element heater 3, reduce the preheating time of steam generator 100, can also avoid heating element heater 3 that the phenomenon of hot-spot occurs simultaneously, be conducive to extending the service life of heating element heater 3.Alternatively, multiple second apopores are evenly spaced apart to be located at the side of the close partition wall 2 of the 4th water inlet pipe, consequently facilitating the water that the second apopore flows out is injected on partition wall 2 as much as possible.It is understood that when multiple second apopores on the 4th water inlet pipe are very little and eject vaporific little water droplet, above-mentioned advantage can be made to be optimized further.

According to some embodiments of the present invention, the water vapour formed in exocoel 11 is entered after in inner cavity chamber 12 by connectivity slot 21 and forms turbo-steam air-flow.Specifically, the tangent water vapour with formation in exocoel 11 is tangentially entered in inner cavity chamber 12 bearing of trend of connectivity slot 21 with the inner circumferential wall of inner cavity chamber 12, thus forming turbo-steam air-flow.

Specifically, by above-mentioned connectivity slot 21 set-up mode, under the heating of heating element heater 3, water vapour in exocoel 11 tangentially enters into inner cavity chamber 12 by connectivity slot 21, and in inner cavity chamber 12, form cyclonic air flow, water vapour is contacted with the internal face of inner cavity chamber 12, cyclonic air flow can form the effect of similar cyclone separator simultaneously, make the aqueous water in water vapour get rid of on the inwall of inner cavity chamber 12 by rapid vaporization or flow downward along it, and under the heating of heating element heater 3, forming steam further.Thus, not only can avoid the internal face of inner cavity chamber 12 that the phenomenon of hot-spot occurs to a certain extent on the one hand, be conducive to improving the service life of heating element heater 3, the efficiency of heating surface of heating element heater 3 can also be improved simultaneously, shorten the preheating time of steam generator 100, and improve temperature and the aridity of steam (vapor) outlet 14 steam, incrustation scale in water vapour is thrown toward the internal face of inner cavity chamber 12 on the other hand, and it is attached on the internal face of inner cavity chamber 12, thus reducing incrustation scale to a certain extent to discharge probability from steam (vapor) outlet 14, avoid the harm that incrustation scale blocking steam (vapor) outlet 14 brings.

Alternatively, as shown in Fig. 6, Fig. 8, Figure 11-Figure 15, connectivity slot 21 is formed at the top of partition wall 2 and the roof (such as adjacent caps 16) of contiguous housing 1.Thus, the water vapour formed after being conducive to the heating of heated element 3 move up and from exocoel 11 enter into in inner cavity chamber 12.

Some further embodiments according to the present invention, as shown in Figure 3 and Figure 4, steam generator 100 also includes supercharging switching device 4, and supercharging switching device 4 is located at steam (vapor) outlet 14 place so that the water vapour of base 15 is from the unidirectional discharge of steam (vapor) outlet 14.The supercharging switching device 4 being arranged on steam (vapor) outlet 14 place can make the steam in housing 1 discharge from steam (vapor) outlet 14 at the uniform velocity high pressure.Specifically, when heating element heater 3 heats, the aqueous water in housing 1 is constantly vaporized into water vapour.In the process, in housing 1, pressure constantly increases, and when the pressure in housing 1 is more than setting value, supercharging switching device 4 is opened so that dry steam is discharged rapidly from steam (vapor) outlet 14 high pressure.When the pressure in housing 1 reduces to during equal to or less than setting value, supercharging switching device 4 cuts out until when pressure in housing 1 reaches setting value again, supercharging switching device 4 is just opened.Thus, the supercharging switching device 4 being arranged on steam (vapor) outlet 14 place can make to remain certain pressure in housing 1, this is not only advantageous to and improves the saturation temperature of steam in housing 1 further, to improve temperature and the aridity of the steam at steam (vapor) outlet 14 place, and also advantageously improve the velocity of discharge of water vapour, ensure that water vapour continues to discharge from steam (vapor) outlet 14, it is to avoid the phenomenon of the steam continuous decrement of steam (vapor) outlet 14.Wherein it is possible to be understood by, the pressure set points in housing 1 is relevant with the weight of supercharging switching device 4, therefore, can pass through the weight adjusting supercharging switching device 44 with the pressure set points in adjustment housings 1.

Further, as Figure 3-Figure 4, lid 16 downwardly extends out prominent post 161, limit bottom in prominent post 161 and there is the half-duplex channel 1612 of passway 1611, the upper end of half-duplex channel 1612 connects with steam (vapor) outlet 14, supercharging switching device 4 is located in half-duplex channel 1612, thus, not only simple in construction, and the prominent post 161 that lid 16 downwardly extends out increases the surface area in housing 1, so that incrustation scale is attached on the outer surface of prominent post 161, avoid the damage of the steam generator 100 caused because incrustation scale is too much to a certain extent, extend the service life of steam generator 100.Certainly, the invention is not restricted to this, lid 16 can also be not provided with prominent post 161.

Alternatively, the cross section of prominent post 161 is formed as annular, and prominent post 161 its cross-sectional area on the direction away from lid 16 is more and more less.

In some further concrete examples of the present invention, as it is shown on figure 3, supercharging switching device 4 includes sealing member 41 and flexible member 42.Wherein, sealing member 41 is in the elastic deformation active force lower seal passway 1611 of flexible member 42.Such as, sealing member 41 is positioned at half-duplex channel 1612 and lower end closed passway 1611, and flexible member 42 is only against between steam (vapor) outlet 14 and sealing member 41 so that sealing member 41 seals passway 1611 according to the elastic deformation active force of flexible member 42.Thus, when heating element heater 3 heats, pressure in housing 1 constantly increases, when the pressure in housing 1 is more than setting value, Steam Actuation sealing member 41 in housing 1 is upwardly so that flexible member 42 is in compressive state, consequently facilitating water vapour is by passway 1611 and further across half-duplex channel 1612, and finally discharge from steam (vapor) outlet 14, when the pressure in housing 1 is less than or equal to setting value, sealing member 41 is pressed on passway 1611 and sentences closed channel mouth 1611 by flexible member 42.

This is not only advantageous on the one hand and improves the saturation temperature of water vapour in housing 1 further, to improve temperature and the aridity of the steam at steam (vapor) outlet 14 place, and also advantageously improve the velocity of discharge of water vapour, ensure that water vapour continues to discharge from steam (vapor) outlet 14, it is to avoid the phenomenon of steam continuous decrement；Flexible member 42 is set on the other hand and the incrustation scale in water vapour and aqueous water can also be blocked in housing 1 by sealing member 41, not only can avoid because incrustation scale is discharged in the pipeline being connected with steam (vapor) outlet 14 blocking of the pipeline caused with water vapour, but also further increase the aridity of the water vapour discharged from steam (vapor) outlet 14.Wherein, it is understandable that, the setting value of the pressure in housing 1 and flexible member 42 and the weight of sealing member 41, the coefficient of elasticity of flexible member 42 and deformation length are relevant, therefore, can pass through to adjust flexible member 42 and the weight of sealing member 41, the coefficient of elasticity of flexible member 42 and deformation length, thus the setting value of the pressure adjusted in housing 1.

Alternatively, sealing member 41 can be the shapes such as spheroid, cylinder, cone or cuboid, it is, of course, understood that sealing member 41 can also have other shape, as long as closing and opening passway 1611.Alternatively, sealing member 41 can be piston, and flexible member 42 is spring.

Certainly, the invention is not restricted to this, in other embodiments of the present invention, supercharging switching device 4 includes the check valve sheet being located at steam (vapor) outlet 14 place.Such as, supercharging switching device 44 can be check valve sheet so that steam in housing 1 is from the unidirectional discharge of steam (vapor) outlet 14, simple in construction.

In some embodiments of the invention, inner cavity chamber 12 and exocoel 11 can be heated by heating element heater 3 simultaneously, say, that in the whole work process of heating element heater 3, and inner cavity chamber 12 and exocoel 11 are heated by heating element heater 3 all the time simultaneously.Certainly, the invention is not restricted to this, when heating element heater 3 is just started working, heating when heating element heater 3 is to inner cavity chamber 12 and exocoel 11 difference, after a period of time, inner cavity chamber 12 and exocoel 11 are heated by heating element heater 3 simultaneously.Such as, when in a period of time (such as 5S) that heating element heater 3 has just been started working, first heating element heater 3 heats exocoel 11, so that the water in exocoel 11 can become water vapour under the heating of heating element heater 3 as soon as possible and enter into inner cavity chamber 12, after a period of time (such as 5S), heating element heater 3 is heating bore room 12 and exocoel 11 simultaneously, so that heating element heater 3 continues the water in heating exocoel 11 and the water vapour entered in inner cavity chamber 12 is continued heating, thus improving the aridity of the water vapour discharged from steam (vapor) outlet 14.

According to some embodiments of the present invention, as shown in Figure 6, steam generator 100 also includes at least one gaining structure 7.Gaining structure 7 is accommodated in the inner in chamber 12 and/or exocoel 11, such as gaining structure 7 can only be accommodated in the inner in chamber 12, or gaining structure 7 can only be contained in exocoel 11, or gaining structure 7 includes multiple and is respectively received in inner cavity chamber 12 and exocoel 11.Thus, by arranging gaining structure 7 in inner cavity chamber 12 and/or exocoel 11, it is not only advantageous to the surface area increased in inner cavity chamber 12 and/or exocoel 11, so that more incrustation scale is attached on gaining structure 7, thus improving the service life of steam generator 100 to a certain extent, but also be conducive to the flowing stopping incrustation scale with water vapour, to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14.

Gaining structure 7 contacts with partition wall 2, thus, the heat that can be easy to heating element heater 3 generation passes to gaining structure 7, so that the heat exchange between gaining structure 7 and the water vapour and/or the water that flow through gaining structure 7, thus increasing heat exchange area, be conducive to improving the utilization rate of the heat of heating element heater 3, reduce the working time of heating element heater 3 to a certain extent, extend the life-span of heating element heater 3 and indirectly extend the service life of steam generator 100, also advantageously improving temperature and the aridity of water vapour simultaneously.

Preferably, gaining structure 7 does not contact with the medial wall (i.e. the medial wall of the medial wall/base 15 of housing 1) of exocoel 11, thus avoiding to a certain extent because the medial wall of gaining structure 7 with exocoel 11 contacts to the external radiation heat of steam generator 100.Certainly, the invention is not restricted to this, gaining structure 7 can be simultaneously connected with on the medial wall of the lateral wall of partition wall 2 and exocoel 11.

Further, gaining structure 7 is connected on partition wall 2, for instance gaining structure 7 and partition wall 2 are formed in one part, simple in construction.Certainly, the invention is not restricted to this, gaining structure 7 also may be provided on the roof (such as lid 16) of housing 1, and gaining structure 7 extends downwardly in inner cavity chamber 12 and/or exocoel 11, and contacts with partition wall 2.

Specifically, between the lower end of gaining structure 7 with the diapire of housing 1 spaced apart, consequently facilitating the flowing of the circulation of the water of the bottom of housing 1 (bottom of lid 16) and incrustation scale, it is to avoid make incrustation scale accumulate in this position because the lower end of gaining structure 7 contacts with the diapire of housing 1.Alternatively, the cross section of gaining structure 7 is formed as substantially " ten " word shape, and the cross-sectional area of gaining structure 7 is gradually reduced on direction from top to bottom.Certainly, the invention is not restricted to, gaining structure 7 may be formed as other shape, for instance the tabular extended up and down.

Alternatively, gaining structure 7 includes multiple, and circumferentially disposed around partition wall 2 of multiple gaining structure 7.Specifically, multiple gaining structure 7 being provided at circumferentially spaced around partition wall 2.Such as, gaining structure 7 includes four, and four gaining structures 7 are contained in exocoel 11 and uniform intervals setting in the circumference of partition wall 2.It is understood that the size and dimension between multiple gaining structures 7 can be identical, it is also possible to be different.

According to some embodiments of the present invention, steam generator 100 also includes at least one and holds dirt structure, holds dirt structure and is arranged in inner cavity chamber 12 and/or exocoel 11.Such as, hold dirt structure to be only located in inner cavity chamber 12 or hold dirt structure and be only located in exocoel 11 or hold dirt structure and be multiple and be respectively provided in exocoel 11 and inner cavity chamber 12.Thus, by arranging appearance dirt structure, it is not only advantageous to the surface area increased in inner cavity chamber 12 and/or exocoel 11, so that more incrustation scale is attached in appearance dirt structure, thus improving the service life of steam generator 100 to a certain extent, but also be conducive to the flowing stopping incrustation scale with water vapour, to reduce the probability that incrustation scale flows out from steam (vapor) outlet 14.

Further, with reference to shown in Figure 10-Figure 18 figure, holding dirt structure is at least one in mesh grille 81, strip grid 82 and column grid 83.

Such as, as shown in Figure 13 and Figure 15, holding dirt structure is mesh grille 81, thus it is not only advantageous to the surface area increased in housing 1, so that more incrustation scale is attached on mesh grille 81, improve the service life of steam generator 100 to a certain extent, and the mesh on mesh grille 81 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 81 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 81 can be formed as circular port or hexagonal hole or other shapes of hole, this is not construed as limiting by the present invention.It is understood that the size of the multiple mesh on mesh grille 81 can be identical, naturally it is also possible to be different.Alternatively, the size of the mesh on mesh grille 81 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 81.

Alternatively, mesh grille 81 can include multiple, and multiple mesh grille 81 interval in residing chamber (i.e. exocoel 11 and/or inner cavity chamber 12) is arranged.Such as shown in Figure 13 and Figure 15, three mesh grille 81 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 17-Figure 18, holding dirt structure is strip grid 82, thus it is not only advantageous to the surface area increased in housing 1, so that more incrustation scale is attached on strip grid 82, 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 82 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 exterior line caused because of the incrustation scale on drainage screen.Additionally, owing to each grate opening of strip grid 82 extends in the short transverse of strip grid 82, therefore after strip grid 82 stops incrustation scale, incrustation scale can be deposited on downwards the bottom of strip grid 82 under gravity, thus reducing the probability that strip grid 82 is blocked by incrustation scale, it is ensured that the area of passage of water vapour on strip grid 82, and then make water vapour when flowing through strip grid 82, 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 82, 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 82 can include multiple, and multiple strip grid 82 interval in residing chamber (i.e. exocoel 11 and/or inner cavity chamber 12) is arranged.Such as shown in figure 18, three strip grid 82 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 81 and/or strip grid 82 are located in exocoel 11, and the two ends of mesh grille 81 and/or the two ends of strip grid 82 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 81 in exocoel 11, the two ends of mesh grille 81 are connected with the lateral wall of the medial wall of exocoel 11 and partition wall 2 respectively, when only arranging strip grid 82 in exocoel 11, the two ends of strip grid 82 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 82 and mesh grille 81 in exocoel 11, strip grid 82 and the respective two ends of mesh grille 81 are connected with the lateral wall of the medial wall of exocoel 11 and partition wall 2 respectively.Thus, the water vapour in exocoel 11 can be passed through and have to pass through mesh grille 81 and/or strip grid 82 could continue flow forward, thus reliably stopping the incrustation scale flowing with water vapour.

Specifically, with reference to Figure 14, the medial wall of exocoel 11 and the lateral wall of partition wall 2 are respectively formed with the first draw-in groove 84 and the second draw-in groove 85, the two ends of mesh grille 81 and/or the two ends of strip grid 82 are fastened in the first draw-in groove 84 and the second draw-in groove 85 respectively, thus, can mesh grille 81 and/or strip grid 82 be securely fixed in exocoel 11, avoid because mesh grille 81 and/or the fixing loosely mesh grille 81 caused and/or strip grid 82 movement or rock the result of use affecting mesh grille 81 and/or strip grid 82 exocoel 11 in of strip grid 82.

Such as, in the concrete example of Figure 14, first buckle slot and the second draw-in groove 85 are all in the upper extension of the short transverse (i.e. the short transverse of base 15) of housing 1, thus strip grid 82 and/or mesh grille 81 being securely fixed between exocoel 11 and partition wall 2.Specifically, the first draw-in groove 84 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 85 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.

In the further embodiments of the present invention, as shown in Figure 10-Figure 12, column grid 83 is positioned at exocoel 11 and/or inner cavity chamber 12, and column grid 83 includes generally radially extending multiple extension bars 831.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 831, also can improve the service life of steam generator 100 to a certain extent, and the setting extending bar 831 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 83 includes along the short transverse of housing 1 is distributed extends bar 831, often circle extend bar 831 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 831 is interlaced with each other in the height direction to be opened, for instance, the multi-turn in the upper distribution of housing 1 short transverse (such as the short transverse of base 15) extends bar 831 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 831, 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.
