Composite working tube and solar energy steam-generating equipment

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.

Description

technical field [0001] The invention relates to a solar heating device and a solar steam generating device, in particular to an integrated working tube and a solar steam generating device. It belongs to the technical field of solar energy equipment. Background technique [0002] Chinese patent announcement number: CN 101344020A, announcement date: January 14, 2009, the invention name "solar tower-type focused high-temperature heat-collecting steam boiler-steam turbine power generation device" is arranged on the ground around the high tower and installed n each by a plane The solar heat collection unit composed of reflector, sun tracking sensor and its control mechanism automatically tracks the sun and reflects sunlight from different positions to the focal point on the top of the tower—around the solar steam boiler, heating the solar steam boiler to generate steam pressure, and driving The rotation of the steam turbine drives the generator to generate alternating current, w...

AI Technical Summary

Problems solved by technology

[0005] The first purpose of the present invention is to provide a combined work tube with small heat loss, good heat preservation effect and high thermal efficiency in view of the defects and deficiencies of the existing tower-type thermal focuser, which have large reflected light heat loss and poor heat preservation effect of the focuser.
