Double-focal-spot dual-purpose solar furnace

Abstract

The invention relates to a double-focal-spot dual-purpose solar furnace which can solve the problems that the equipment structure is complicate, the cost is high, and the solar energy can not be fully utilized. The double-focal-spot dual-purpose solar furnace is characterized in that a heliostat is arranged on a support, the upper and lower edges of the support are provided with guy wires used for adjusting direction of the heliostat, the guy wires are connected with a regulating handle through guy wire wheels, the regulating handle is arranged on the support, and the lower part of a heat absorption furnace is arranged on a motion track through a pulley; the heat absorption furnace has an opening in the direction facing a light-reflecting surface of the heliostat, the rear part of the opening is provided with a condenser in a box, and the condenser is placed on a focal spot formed by focal points on which the double-focal-spot spotlight heliostat condenses light in the dual-purpose heat absorption furnace, so that the condenser focuses on the lower bottom surface of a heat absorption disc body arranged on the upper part in the dual-purpose heat absorption furnace, the heat absorption disc body is provided with water inlet and outlet pipelines communicated with the inside of the disc body and stretching out outside of a heat absorption furnace shell, and the centres of the focal spots and the lower edge of the heliostat are positioned in the same horizontal plane. The double-focal-spot dual-purpose solar furnace provided by the invention has the advantages of simple structure, unique novelty, low cost, easiness in installation and use, good using effect, and can effectively utilize solar energy in morning and afternoon.

Description

technical field [0001] The invention relates to solar energy, in particular to a dual focal spot dual-purpose solar furnace utilizing solar energy. Background technique [0002] Solar furnaces and other heat collectors generally use a single focal spot parabolic reflector as the concentrator, and the receiver is placed on the focal point of the condensing mirror and moves together to perform primary or secondary concentrating to obtain heat energy; the change in the angle of incident light will cause different The degree of aberration affects the size, shape and collected power of the focal spot, so the sun is tracked by dual-axis or single-axis drive tracking to ensure that the incident direction of sunlight is parallel to the main optical axis. Aberration caused by motion, but due to the limitation of the receiver's mirror surface and its own gravity, the cost of realizing high-power solar furnaces increases sharply, so it is also limited. [0003] The purpose of the vari...
