Description
Technical field
The present invention relates to utilize sun power to carry out the experiment field of water treatment, relate in particular to a kind of sunlight that utilizes and carry out the sunlight intensity stabilizing deyice of using in the water treatment experiment of catalyzed oxidation.
Background technology
Day by day under the serious situation, the utilization of solar energy is subjected to people day by day and payes attention in current energy dilemma, and the solar energy utilization is also toward the infiltration of people's various fields in life.The sunlight catalytic oxidation is a new branch in its numerous application in the application of water treatment field, and this part is used because the shortage in condition and the research, still is in the stage of research.Be the research of being correlated with preferably, stable sun light intensity is the condition an of necessity.And actual sunlight is because the real-time change of factors such as altitude of the sun and cloud layer, and sun light intensity is in the continuous change procedure all the time, and this research to the sunlight catalytic oxidation characteristic is totally unfavorable.For satisfying the needs of research, people generally solve by two kinds of approach at present: a kind of is to select the altitude of the sun maximum, the time period that the while sky does not block experimentizes, and this moment, sun intensity variations was in a metastable interval, can satisfy the experiment needs substantially; Another kind then is to adopt manual simulation's solar source to carry out Related Experimental Study, also can satisfy specific research needs.
Yet above two kinds of approach all have certain limitation, and first kind of situation that more needs to rely on weather makes on the progress of research and result's the accuracy to have certain query part; Though and the second way can be simulated the sun light intensity of a certain specific band preferably, can't be fully match, thereby on a certain degree, experimental result is affected with the spectrum of the whole sun.Therefore need a kind of novel device of exploitation, can guarantee to keep than stable light intensity under study for action.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of sunlight strong stability device that is used for sunlight catalytic oxidation experiment research usefulness, make in the experimentation, sunlight intensity is in a metastable state all the time.
