2, SO
2Environment is produced very big harm, danger utmost point human existence.Utilize solar electrical energy generation, consumes energy does not have toxic emission, has development potentiality and application prospect.The tower type solar generated output is big, good reliability, generating efficiency height.In tower-type solar thermal power generating system, be that solar receiver is realized the most key core technology of tower type solar energy thermal power generation, the solar energy that it is caught heliostat, reflect, focus on is converted into the high temperature heat that can efficiently utilize, for generating set provides required thermal source or power source, thus the process of realization solar energy thermal-power-generating.At present, many countries invest in succession to this Study on Technology, and starting Europe, the United States and state such as Israel early technically obtained important breakthrough at this.
The utility model content
The purpose of this utility model is to provide a kind of tower type solar Natural Circulation receiver, the utlity model has have reasonable in design, applied widely, energy utilization rate height, the characteristics that cost is low.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of tower type solar Natural Circulation receiver comprises that drum, water inlet pipe, steam go out pipe, go up return tube, go out water manifold, high pressure vacuum solar energy heat collection pipe and base down; 1 the end of wherein intaking is fit into below 1/2nd degree of depth of drum, and steam goes out pipe and is installed in the drum top; The side of drum is equipped with return tube, and last return tube links to each other with an end of high pressure vacuum solar energy heat collection pipe, the other end of high pressure vacuum solar energy heat collection pipe with under go out water manifold and link to each other; Under go out water manifold and drum bottom and be communicated with; And under go out water manifold and be installed on the base.
Described drum is wrapped with adiabatic asbestos housing.
Described high pressure vacuum solar energy heat collection pipe is that glass is made; Water inlet pipe and steam go out pipe and last return tube is a metal tube.
The beneficial effects of the utility model are: the utility model utilization be positioned at the receiver center drum dress water under go out water manifold and flow to the high pressure vacuum solar energy heat collection pipe, in the high pressure vacuum solar energy heat collection pipe, the high heat flux radiant energy that the heliostat systematic reflection comes, be translated into the high temperature heat of water, the water heating evaporation is a high temperature and high pressure steam, steam to drum the first half, produces high pressure superheated steam from last return tube, is stored in the drum.Go out let off steam steam turbine pushing turbine generating of pipe from steam then, the general gas of steam turbine is got back to water inlet pipe through the cold doubtful water water pump pressure of cold doubtful device, finishes a working cycles.The advantage of receiver of the present utility model is that it can be installed several high pressure vacuum solar energy heat collection pipes and receives sunshine from settled date mirroring in the 360 degree scopes around the tower, focusing around drum, helps the layout designs of heliostat Jing Chang and the extensive utilization of solar energy.Have reasonable in design, applied widely, energy utilization rate height, the characteristics that cost is low.
