But realizing in process of the present utility model, inventor finds, at least there is following defect in prior art:
When heat transfer medium adopts when water, the similar direct current cooker of receiver, water all becomes superheated steam at heating surface through preheating, evaporation, after overheated; The shortcoming of this kind of receiver is: due to evaporation and overheated heating surface there is no obvious boundary, there is sometimes flowing instability and pulse state at evaporating heating surface, the coefficient of heat transfer of adding superheat section part superheated steam and heating surface is lower, therefore, in the time that the variation of solar energy instantaneous load is larger, very easily there is the rough sledding such as tube wall temperature is too high, thermograde is large, thermal stress is excessive, thereby affect stability and the security of receiver operation.
Utility model content
The defect existing for prior art, the utility model provides a kind of tower type solar directly to produce superheated steam receiver, evaporimeter and superheater are set as heat exchanger independently, drum can play cushioning effect simultaneously, therefore, improve the hydrodynamic stability in receiver, made temperature, the pressure of receiver outlet superheated steam more easy to control, improved resistance to overturning and security.
The technical solution adopted in the utility model is as follows:
The utility model provides a kind of tower type solar directly to produce superheated steam receiver, comprising: thermal-arrest tower 2, evaporimeter 4, drum 5, superheater 6, inlet duct and outlet conduit; Wherein, offer cavity 3 on the top of described thermal-arrest tower 2, described evaporimeter 4 and described superheater 6 are arranged at described cavity 3 inside, at the tower top of described thermal-arrest tower 2, described drum 5 are installed, and described drum 5 is built-in with steam-water separator; And, the entrance of described evaporimeter 4 is communicated with described inlet duct, the outlet of described evaporimeter 4 is connected to the entrance of described steam-water separator, and the outlet of described steam-water separator is connected to the entrance of described superheater 6, and the outlet of described superheater 6 is communicated with described outlet conduit.
Preferably, be also provided with reflecting plate at the sidewall of described cavity.
Preferably, described reflecting plate is parabolic condenser.
Preferably, the aperture position of described cavity 3 seals by glass plate.
Preferably, at the coated insulation material in the outside of described cavity 3.
Preferably, described insulation material applies heat absorbing coating outward.
Preferably, described thermal-arrest tower 2 is steel structure tower or armored concrete tower.
The tower type solar that the utility model provides directly produces superheated steam receiver and has the following advantages:
(1) evaporimeter and superheater are set as heat exchanger independently, drum can play cushioning effect simultaneously, therefore, has improved the hydrodynamic stability in receiver, make temperature, the pressure of receiver outlet superheated steam more easy to control, improved resistance to overturning and security.
(2) because cavity inside arranges evaporimeter and superheater produces final superheated steam, therefore, reduce the resistance to pressure of the glass plate to being installed on cavity opening, thereby both improved the job security of receiver, the manufacturing cost of having saved again receiver.
Brief description of the drawings
The tower type solar that Fig. 1 provides for the utility model directly produces the structural representation of superheated steam receiver.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
In conjunction with Fig. 1, the utility model provides a kind of tower type solar directly to produce superheated steam receiver, comprising: thermal-arrest tower 2, evaporimeter 4, drum 5, superheater 6, inlet duct and outlet conduit; Wherein, offer cavity 3 on the top of described thermal-arrest tower 2, described evaporimeter 4 and described superheater 6 are arranged at described cavity 3 inside, at the tower top of described thermal-arrest tower 2, described drum 5 are installed, and described drum 5 is built-in with steam-water separator; And, the entrance of described evaporimeter 4 is communicated with described inlet duct, the outlet of described evaporimeter 4 is connected to the entrance of described steam-water separator, and the outlet of described steam-water separator is connected to the entrance of described superheater 6, and the outlet of described superheater 6 is communicated with described outlet conduit.The aperture position of cavity 3 seals by glass plate.
In addition, can also be provided with reflecting plate in cavity sidewalls, reflecting plate can be parabolic condenser.By at cavity inner wall, reflecting plate being set, can improve the utilization rate of sunshine, can make again solar irradiation be mapped to the shady face in cavity, thereby effectively reduce temperature difference and the stress difference of tube wall.
