Movable solar heat collection linear receiver and use method thereof

Abstract

The invention provides a movable solar heat collection linear receiver and a use method thereof. The movable solar heat collection linear receiver comprises an assembly rack, multiple reflector units arranged above the assembly rack, supports, a sliding match component and driving mechanisms, wherein the multiple reflector units form a Fresnel reflector; the supports are arranged on the middle part of the assembly rack; a heat receiver is movably arranged above the supports, and extends along the light beam intersection zone of the Fresnel reflector; the sliding match component is arranged between the supports and the heat receiver and is used for the heat receiver to reciprocate along a straight line on which the light beam intersection zone of the Fresnel reflector is located; and the driving mechanisms provide driving power for the linear reciprocating motion of the heat receiver. The movable solar heat collection linear receiver is used for solving the problem of a conventional solar energy receiver of seasonal periodical end loss, so that solar energy gathered by the Fresnel reflector can be fully collected.

Description

technical field [0001] The invention relates to the field of special equipment for solar energy concentration and heat collection, in particular to a movable linear receiver for solar energy heat collection and a use method. Background technique [0002] The solar heat collection system is the basic component of solar heat utilization. In the process of solar heat collection and utilization such as trough, Fresnel, and compound paraboloid, the light spot on the receiver generally presents a linear light spot belt, so it is called solar energy. linear receiver. Since the geographical location of solar collectors is not all near the equator at low latitudes, the sun is always in the south north of the Tropic of Cancer. For linear solar collectors placed horizontally from north to south, as long as the sunlight cannot be vertical Part of the focused solar spot falls outside the linear absorber, and there is always terminal loss on the absorber. For details, refer to figure 1 ...

Problems solved by technology

Although the former method increases the investment of the receiver, in a certain season period, there is always an extra area on the surface of the receiver that cannot be covered by the light band, thereby increasing the probability of external heat loss; the disadvantage of the latter method is that Need to take into account the weight of the receiver and the mechanism of control adjustment is relatively complicated
