Technical field
The utility model belongs to atom light radiation technical field, is specifically related to a kind of circulating optical radiation energy exchange steam generating system.
Background technology
87in Rb atomic energy level transition process, two hyperfine levels transition frequencies of ground state are about 6835MHz, and first excited state has two fine-structure energy levels 5

2p
1/2, the hyperfine splitting of these two energy levels is little compared with ground state, is respectively 840MHz (F=3 and F=0) and 430MHz (F=2 and F=1).Due to dopplerbroadening, to divide therewith value difference few, therefore the hyperfine structure of excitation state cannot be differentiated.Therefore
87the first excited state of Rb atom and the transition spectral line between ground state only include D

2two hyperfine structure composition a lines of line and b line.
In ground state level | F=2, m

fbetween these two energy levels of=0>, the exact value of jump frequency is 6834.68XXXX MHz (external magnetic field H=0), and rear 4-digit number is determined by system perturbation.By checkout gear, obtain
87the absorption line of Rb.This spectral line can be used as frequency discrimination spectral line.But due to gaseous state
87rb population density is little, | F=2, m

f=1> two energy gaps are less, when normal temperature two energy level populations poor be very little, therefore finally by the resulting absorption line of this device very faint.

Accompanying drawing explanation
Fig. 1 is the structural representation of the circulating optical radiation energy exchange of the utility model embodiment steam generating system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
A circulating optical radiation energy exchange steam generating system, upper cover 1, upper shell 2, bullet 3, lower shell 4 and low head 5, described upper cover 1, upper shell 2, bullet 3, lower shell 4 and low head 5 are connected from top to bottom successively; Described upper cover 1 top is provided with steam outlet pipe 11, in steam outlet pipe 11, be provided with the current limiter 12 that several minor diameter Venturi tubes form, the inner steam-water separator of installing of upper shell 2, steam-water separator is comprised of tubular whirlwind separator 21 and corrugated plating separator 22, tubular whirlwind separator 21 is for crude separation, corrugated plating separator 22 for segmentation from, after the separation of two-stage carbonated drink, the humidity of saturated vapor can be less than 0.25%.On upper shell 2 walls, be symmetrical arranged water supply connecting tube 23 and auxiliary water inlet pipe 24, water supply connecting tube 23 is connected with the feedwater endless tube 25 of inner barrel respectively with auxiliary water inlet pipe 24, feedwater be provided with on endless tube 24 some non-homogeneous layouts to water distribution pipe, feedwater endless tube 25 with to water distribution pipe, by T junction, be connected; Lower shell 4 inside arrange U-shaped heating surface bank 41 and tube bank sleeve 42, and tube bank sleeve 42 is positioned at U-shaped heating surface bank 41 skins; Like this, feedwater flow is along the optimal allocation of circulating line.80% feedwater is assigned to the hot side of heating surface bank, and 20% feedwater is assigned to cold side, guarantees the evaporation capacity of hot and cold both sides about equally, has avoided the thermosyphon action between both sides.Described low head 5 comprises coolant inlet hydroecium 51 and coolant outlet hydroecium 52, is section's nickel dividing plate 53 between coolant inlet hydroecium 51 and coolant outlet hydroecium 52.
When the circulating optical radiation energy exchange steam generating system of the present embodiment moves, cooling agent enters import hydroecium 51 by low head 5 inlet nipple, then by U-shaped heating surface bank 41, transfer heat to secondary circuit side working medium, cooling agent passes through outlet hydroecium 52 after flowing out U-shaped heating surface bank 41, from low head outlet ozzle, flow out again, by main pump, be transmitted back to reactor.
Meanwhile, the decline passway being comprised of the passage by between tube bank sleeve 42 inner sides and U-shaped heating surface bank 41, the rising passway in U-shaped heating surface bank 41 form closed circuit with tube bank sleeve 42 breach and the steam-water separator that are connected them.What in closed circuit, in decline passway, flow is single-phase cold water, and the carbonated drink that in rising passway, mobile temperature is higher and the hot water of mixing, forms not identical water columns of two temperature and density.Under same system downforce, the density contrast of cold water post and hot water post forms the driving force of Natural Circulation, drive cold water to flow downward along decline passway, steam water interface is along rising passway to upper reaches, thereby set up Natural Circulation, in the upper-part centralized water tank of cold water post and the how circulating optical radiation energy exchange system of hot water post, contact, carry out the separation of vapour-water, the current recirculation of vaporization part does not enter cold water post.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
