Solar steam generator

Abstract

The invention discloses a solar steam generator and belongs to the technical field of steam generators. The solar steam generator comprises a group of heat collector tubes, wherein each heat collector tube comprises a vacuum glass tube which is internally provided with a focusing reflector; a solar tracker for prompting the focusing reflector to align to the sun is arranged on the focusing reflector; the vacuum glass tube forms an enclosed cavity through a copper flange connected to a port thereof; a heat guide tube of which the tail part is provided with a shunt device is inserted into the enclosed cavity; a water inlet branch pipe is inserted into the heat guide tube; the front end of the heat guide tube is connected with a steam pipe which is communicated with the heat guide tube; a water inlet pipe is inserted into the steam pipe; and the water inlet pipe is communicated with the water inlet branch pipe inserted into the heat guide tube. The solar steam generator has the advantages of simple and novel structure, reasonable design and high heating efficiency, and can reach the corresponding temperature within 20 to 30 minutes at the solar radiation intensity of 400-600W / cm<2>.

Description

technical field [0001] The invention belongs to the technical field of steam generators, and in particular relates to a solar steam generator. Background technique [0002] With the crisis of traditional energy and the deteriorating environment, it is imperative to develop new and renewable energy. Solar energy is both primary energy and renewable energy. It is rich in resources, can be used for free, does not need to be transported, and has no pollution to the environment. It has created a new life form for human beings, and brought society and human beings into an era of saving energy and reducing pollution. Making full use of solar energy must be an important means to realize national energy conservation and emission reduction. [0003] Traditional steam generators usually use coal heating or electric heating to generate steam. This type of steam generator has great safety hazards, waste of resources, low efficiency, and environmental pollution. There are also some so...

Problems solved by technology

[0003] Traditional steam generators usually use coal heating or electric heating to generate steam. This type of steam generator has great safety hazards, waste of resources, low efficiency, and environmental pollution.

Now there are also some solar steam generators, which have the disadvantages of complex structure and high production cost, and are not suitable for large-scale promotion and utilization.
