As shown in figure 8, not adding the heavenwards of heat dump 1 of baffle plate 3 and ground carries out heat radiation, according to actual conditions, to
The heat of the heat much larger than earthward radiation loss of sky thermal radiation loss.The collection of heat dump in tower type solar electricity generation system
Hot temperature is higher, and up to 600 DEG C, at present in the radiation loss of tower heat dump, heat loss through radiation accounts for total internal heat transfer working medium
The thermal radiation loss of the 70%~90% of heat loss, predominantly heat dump outer wall and sky, the heat-conducting medium temperature in heat dump
Higher, heat loss is bigger, and the size of its heat loss is directly connected to the optical and thermal efficiency of system.
Radiation loss is prevented as example so that tower trapezoidal baffle plate is actual below, calculates the application effect of baffle plate：
Tower heat dump radiation loss schematic diagram is as follows：
Wherein 1 is heat dump, and 2 is ground, and grey arrow is the heat of heat dump heavenwards radiation, and black arrow is heat absorption
The heat that device is earthward radiated.
According to the actual condition of tower receiver, heat loss through radiation situation of the approximate estimation heat dump to sky.Wherein 1 is suction
Hot device, 2 is ground, and 3 is baffle plate.Receiver H=6.2m high, diameter d=5.1m.It is now assumed that four kinds of operating modes, heat dump surface
Temperature T1=500 DEG C, environment temperature is T2, baffle plate and ground take environment temperature T2=T3, i.e.,.The radiation of heat dump heavenwards dissipates
Heat, and receive the radiation of the earth in certain limit.
(1) operating mode one, summer day：T1=500 DEG C, T2=30 DEG C；
(2) operating mode two, summer evenings：T1=500 DEG C, T2=25 DEG C；
(3) operating mode three, daytime in winter：T1=500 DEG C, T2=-10 DEG C；
(4) operating mode four, night in winter：T1=500 DEG C, T2=-20 DEG C.
Computational methods are as follows：
1) in operating mode 1, in the case of not having baffle plate, heat dump radiates to sky radiation.According to radiation computing formula, will inhale
Hot device is defined as black matrix, and emissivity ε is 1, universe temperature T0=4K, then heat dump be with the Radiant exothermicity of sky
2) in the case where there is baffle plate, thermal-collecting tube is to baffle plate heat loss through radiation.Baffle shapes for trapezoidal, baffle plate and heat dump it
Between angle be 60 °, according to ascent formula
According to radiation computing formula, it is assumed that baffle plate material is the non-aluminum oxide of polishing, emissivity ε1Be 0.02, then heat dump with
The Radiant exothermicity of baffle plate is
Therefore deduce that, baffle plate accounts for thermal-collecting tube heavenwards off-energy per the square meter energy to be blocked
Similarly, the efficiency of blocking of rest working conditions is respectively
η2=98.5%
η3=98.4%
η4=98.2%
As can be seen here, no matter under which kind of operating mode, block heat dump emittance per square meter baffle plate and be attained by 98%.
3) individual layer baffle plate is calculated with the difference on effect of dual-layered baffle plate
When baffle plate is for bilayer, internal layer baffle surface temperature T1=20 DEG C, outer layer baffle surface temperature T2=5 DEG C, baffle plate it is saturating
Rate ε=0.02 is penetrated, then
I.e. heat dump radiates the energy on baffle plate, and the heat for only having 0.8w per square meter is lost in vacuum, it can be seen that,
Loss of the dual-layered baffle plate structure for reducing emittance serves very crucial effect, it is clear that heat dump adds baffle plate
The feasibility and economic benefit to be brought afterwards.
The heat loss situation of four kinds of above-mentioned operating modes is as shown in figure 9, abscissa 1/2/3/4 corresponds to operating mode one to work respectively
Condition four, a in figure is thermal radiation loss when not adding baffle plate 3, and b is thermal radiation loss when using individual layer baffle plate 3, and c is to make
Thermal radiation loss during with dual-layered baffle plate 3；Obviously, either using individual layer baffle plate or dual-layered baffle plate, can be greatly decreased
Heat loss, more than 75% is reduced using thermal radiation loss after individual layer baffle plate, and after dual-layered baffle plate, thermal radiation loss reduces 85%
More than.
Above example is only exemplary embodiment of the invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in essence of the invention and protection domain to the present invention
Modification or equivalent are planted, this modification or equivalent also should be regarded as being within the scope of the present invention.
