Abstract

A composite working tube and solar energy steam-generating equipment belong to the solar energy equipment technical field. The composite working tube comprises a focusing tube with two enclosing ends,heat storage material is fixed on the inner wall of a light collecting surface of the focusing tube, a steam pipe and a water service pipe are arranged above the heat storage material along the direction of the tube range, a steam inlet is arranged on one end of the steam pipe, a water jet is arranged on the water service pipe, a heat-insulated pipe is contained in the outer wall of the focusingtube in a sealing manner, the light collecting surface in corresponding to the focusing tube along the length direction of the heat-insulated pipe is provided with a strip opening, heat insulating material or evacuation is filled between the heat-insulated pipe and the focusing tube, and small weight bearing wheels are evenly fixed. In the solar energy steam-generating equipment, a composite working tube is arranged on the center line position of the reflective curved surface of a solar energy concentrator, and the light collecting surface of the focusing tube faces the reflective curved surface of a solar energy concentrator. By the invention, the problem of heat preservation outside the focusing tube is solved well, the period for producing steam and transferring steam by the focusing pipe is prolonged, the time for producing steam is shortened, the temperature of steam is high, and the photo-thermal comprehensive utilization is high.
