Description
Technical field
The utility model relates to nuclear power generating equipment field, especially a kind of MSR vapor distribution device.
Background technology
Separator MSR(Moisture Separator and Reheater) be by the device of gas-liquid separation in steam in nuclear power plant.Fig. 1 is MSR profile.As shown in Figures 2 and 3, when steam-distribution plate in the MSR now using carries out steam distribution, because dispensing orifice is circular, when steam enters MSR after dispensing orifice, deflection is larger, and then the vapor (steam) velocity and the flow deviation that enter separator are larger, can form larger on-way resistance.Because the circular dispensing orifice shape of tradition is not considered the impact of separator vane group orientation therefore to have certain vapor flow dead angle, affect steam-water separation effect.
Meanwhile, guttiferous to affect velocity gradient larger because taking for the steam that enters separator blade, so reduced the gas-liquid separation effect of separator, increased energy consumption, affects safe operation.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, on-way resistance is little, steam flow distributed uniform, reduce the vapor (steam) velocity and the flow deviation that enter separator, make the even particle distribution of different-grain diameter, reduce water from steam and divide the uneven distribution that enters separator, thereby improve the MSR vapor distribution device of separator separative efficiency.
For achieving the above object, the utility model adopts following technical solution:
A kind of MSR vapor distribution device, described MSR vapor distribution device is a steam-distribution plate, on described steam-distribution plate, is provided with dispensing orifice, and dispensing orifice is oval, and the long axis direction of oval dispensing orifice is consistent with separator vane group arrangement mode.
Preferably, described steam-distribution plate is rectangle.
Preferably, the arrangement mode of described oval dispensing orifice is that order is arranged.
Preferably, the arrangement mode of described oval dispensing orifice is for being staggered.
The beneficial effects of the utility model are: with respect to the circular dispensing orifice of tradition, the oval dispensing orifice of this device makes separator inlet steam flow even, are conducive to carbonated drink separation.Adopt while carrying out assignment of traffic with the steam-distribution plate of oval dispensing orifice, because oval dispensing orifice long axis direction is consistent with separator vane group arrangement mode, can reduce the deflection that enters the steam flow of separator through dispensing orifice, and then reduce the speed and the flow deviation that enter separator, obtain better steam distribution effect and improve carbonated drink separative efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1: a kind of MSR vapor distribution device, its structure is as shown in Figure 4: described MSR vapor distribution device is a steam-distribution plate 13, on described steam-distribution plate 13, be provided with dispensing orifice, dispensing orifice is oval, and the long axis direction of oval dispensing orifice 15 is consistent with the arrangement mode of separator vane group 10; The arrangement mode of described oval dispensing orifice 15 is that order is arranged.
With respect to the circular dispensing orifice of tradition, the oval dispensing orifice 15 of this device makes separator inlet steam flow even, is conducive to carbonated drink separation.Adopt while carrying out assignment of traffic with the steam-distribution plate of oval dispensing orifice 15, because oval dispensing orifice 15 long axis directions are consistent with the arrangement mode of separator vane group 10, can reduce the deflection that enters the steam flow of separator through dispensing orifice, and then reduce the speed and the flow deviation that enter separator, obtain better steam distribution effect and improve carbonated drink separative efficiency.
Meanwhile, because oval dispensing orifice 15 long axis directions are consistent with separator vane group 10 arrangement modes, the dead angle that can eliminate vapor flow, has improved steam-water separation effect.
Adopt after said structure, when steam outflow dispensing orifice enters separator, due to the minimizing of air flow deflector, on-way resistance reduces, make the even particle distribution of different-grain diameter, reduce water from steam and divide the uneven distribution that enters separator, thereby improve separator separative efficiency, reach energy-saving and cost-reducing effect and improve the security that system is moved.
Adopt steam-distribution plate 13 resistances of oval dispensing orifice 15 to reduce more than 7% than steam-distribution plate 13 resistances that adopt circular dispensing orifice.Air-flow is after the steam-distribution plate 15 of oval dispensing orifice 15, and the air-flow distribution that enters separator is also even than adopting the steam-distribution plate of circular dispensing orifice, and VELOCITY DISTRIBUTION is 3.86m/s-1.29m/s; And while adopting the steam-distribution plate of circular dispensing orifice, VELOCITY DISTRIBUTION is 4.50m/s-1.29m/s, velocity gradient is larger.
In addition, for circular dispensing orifice, enter the vapor (steam) velocity gradient of separator blade, increase along with carrying the increase of size droplet diameter, and bulky grain distribution moves down under Action of Gravity Field; And for oval dispensing orifice 15, because steam deflection reduces, the vapor (steam) velocity graded amplitude that enters separator blade is less, VELOCITY DISTRIBUTION is more even than circular dispensing orifice.
Therefore, adopt the steam-distribution plate 13 of oval dispensing orifice not only can reduce resistance, also make the even particle distribution of different-grain diameter, reduce water from steam and divide the uneven distribution that enters separator, thereby improve separator vapor-liquid separation efficiency.
Embodiment 2: a kind of MSR vapor distribution device, its structure as shown in Figure 5: the places different from embodiment 1 are: the arrangement mode of described oval dispensing orifice 15 is for being staggered.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but the not restriction to this programme protection domain; one of ordinary skill in the art should be understood that; on the basis of this programme, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in the protection domain of this programme.
