Technical field
The present invention relates to solar energy thermal-power-generating field, spy relates to a kind of high temperature heat absorber based on disc type solar energy electricity generation system.
Background technology
The generating of disc type solar energy heat have pollution-free, scale flexibly, the advantage such as failure rate is low, construction period be short, receive increasing concern.The temperature of Dish solar thermal power system is very high, more than 1000 DEG C can be reached, relatively be applicable to adopting air as working medium, circulation adopts Brayton cycle, the air of normal temperature and pressure is by after compressor pressurizes, be transported in solar heat absorber, after heat dump heating, promote air turbine acting.
For the Brayton cycle taking air as working medium, maximum temperature is higher, the cycle efficieny of whole system is also higher, this just means that disc type solar energy heat dump must run in high temperature environments, and there is higher heat exchange efficiency and less volume, to realize outlet temperature more than 800 DEG C.And traditional disc type solar energy heat dump can only be up to 600 DEG C.
Chinese invention patent " the external heat dump of compression outer heat machine " (application number: CN201210185384.X) is it is disclosed that the external heat dump of compression outer heat machine, communicate with outer heat machine cylinder body, comprise housing, heat absorption core body, described heat absorption core body is arranged in housing, arrange gas passage along described heat absorption core body, described gas passage is arranged in heat absorption core body, on housing or between housing and heat absorption core body.The advantage of this invention is that thermal source enters in the middle part of heat dump, makes heat-obtaining more direct, makes heat dump can reach the object of fully heat absorption, provide the structure of gas channel in multiple heat absorption core body simultaneously, reduce gas flow resistance, accelerate heat transfer.But this invention and unexposed heat exchanger core body inner structure structure, be not easy to implement, this invention does not simultaneously relate to how utilizing solar energy heat absorbing.
Summary of the invention
In order to solve the not high problem of traditional disc type solar energy heat dump outlet temperature, the present invention designs a kind of disc type solar energy heat dump of cavity type, by arranging aperture on heat dump core body, pressure chamber is made directly to enter heat dump inner chamber through the aperture of heat dump core body, shorten the flow process of air, the pressure loss of air is very little, makes gases at high pressure can bring up to rapidly more than 800 DEG C from 300 DEG C rapidly.
Technical scheme of the present invention is: a kind of high temperature heat absorber for Dish solar thermal power system, comprise heat dump, be used for collecting the condenser of sunshine of dish face reflection, condenser is placed in the front end of heat dump, transparent glass window, is characterized in that: heat dump comprises pressure chamber, heat dump inner chamber, heat dump core body, heat dump shell, admission line and outlet pipe; Transparent glass window and heat dump shell decomposition pressure chamber; Sunshine can focus on heat dump core body through transparent glass window, and heat dump core body is provided with aperture; Air enters into pressure chamber through admission line, enters heat dump inner chamber by the aperture in heat dump core body, flows out heat dump through outlet pipe.Its beneficial effect is: with traditional tubular type heat dump ratio, the flow process of air is very short, and the pressure loss of air is very little.And the volume of heat dump is little, lightweight, is used on the plate of high light concentrating times, the air exit temp of more than 800 DEG C can be realized.
The high temperature heat absorber of Dish solar thermal power system as above, is characterized in that: described high temperature heat absorber also comprises thermal insulation layer, the described thermal insulation layer outer surface being coated in heat dump shell tightly.
The high temperature heat absorber of Dish solar thermal power system as above, is characterized in that: described thermal insulation layer adopts chamotte insulation material, and thickness is 20mm ~ 30mm.Its useful effect is: both can ensure that the heat of heat dump inside does not scatter and disappear, can ensure again the weight of heat dump.
