The present invention discloses one kind of optimized solar heat utilizing scheme and corresponding system. The solar energy induced airflow power generating system with vertical induced jet pipe can utilize solar energy effectively.

Description

Solar energy induced airflow power generating system

Technical field

The invention discloses the optimization embodiment that a kind of solar-powered thermal utilizes, and system equipment for realizing that this scheme provides, a kind of upright injection jet pipe solar energy induced airflow power generating system, as fossil energy on the earth when exhausted, the ultimate energy obtain manner that human survival is rely and used.

Background technique

The imagination of building the solar chimney power station is that Qiao Genshilaiqi (SchliAch) professor by Universitaet Stuttgart proposes, and make with metal frame and plastic board in the chimney power station in his imagination, and the bottom is provided with big thermal-arrest canopy.Retrieval Chinese invention patent: 200410061277.1[Driven by Solar Energy gas flow generating device] and the building method of a 200410073048.1[solar energy chimney generator] etc. patent.The common ground of these patents is: the prototype of having followed Qiao Genshilaiqi solar chimney power station, all be provided with huge solar energy heating canopy, single its expense that is provided with regard to the thermal-arrest canopy just accounts for 70～80% of power station gross investment, and when wind near chimney in the neighbourhood the time, wind-force is with through reaching quite strong, so the intensity of support and light-transmitting plate all must strengthen and strengthen, more XXL construction investment.Because regular maintenance and light-transmitting plate can more and more weaken the transit dose of light, light-transmitting plate must upgrade once in per 5 years, these investment, and the revenue and expenditure the during electric power that is obtained together, making income is negative forever, does not have substantive operation meaning.

Summary of the invention

The purpose of this invention is to provide the induction tunnel that a kind of upright solar-powered thermal utilizes, solar energy induced airflow power generating system, its basic principle is: utilize the radiation heat of solar energy to the air ejection tube wall, air in the induction tunnel was heated by moment, heated air produces and upwards drags the air-flow that rises, and drives air turbine and drives generator for electricity generation.This generation mode need not conventional energy resource, the merit that the injection air that the supply of its power comes from solar radiation fully and produced is brought.Because air-flow is when rising, also constantly heated, air is constantly gone out induction tunnel, make in the induction tunnel and produced huge pressure difference outward with induction tunnel, cool air is from the induction tunnel ingress, the air-flow that is constantly risen is introduced in the induction tunnel, like this, drive air turbine, the air that drives generator for electricity generation is a cool air, its power mass transfer is high especially, and maximum characteristics are, some not have the urgency cool air of being heated, also taken out of induction tunnel by the injection air-flow, this just more XXL the raising of power efficiency factor, shown the bright prospects of solar energy induced airflow body generating.

Technological scheme of the present invention is, based on solar energy induced airflow body this principle of generating electricity, solar energy induced airflow power generating system, only need to make up a upright hollow tubular injection jet pipe, the inner Air Turbine Generator group of installing has just been formed solar energy induced airflow power generating system.

The method of solar energy induced airflow power generating system of the present invention is, a upright hollow tubular injection jet pipe, hollow cavity is the airflow injection chamber in this pipe, tube wall is a solar thermal collector, apply one deck black fever sucking membranous layer at its outer surface, can comprehensive daylighting energy-absorbing, whole induction tunnel is heated by the solar heat the subject of knowledge and the object of knowledge, owing to be evenly distributed with radiating fin at the tube wall inner side surface, increased the area of contact of air with heat diffusion area, more efficient use solar thermal energy, and adopted the high material manufacturing of thermal conductivity, make as materials such as aluminium and aluminum alloys thereof, make air ejection jet pipe thermal-arrest surface be in the work of higher temperature mass transfer all the time, have the device compactness, simple and reasonable, it is convenient to install, and weight is slim and graceful, and is safe and reliable, and make easily, little investment, operational efficiency are high especially, the good characteristics that service time is very remote.

The invention has the beneficial effects as follows, can realize the miniaturization of cell level, big-and-middle-sized intensification, the generation technology that large-scale production solar-powered thermal utilizes has high practicability, and investment is few especially; And simple and reasonable, device is compact, and weight is slim and graceful, and it is convenient to install, and makes easily, and operational efficiency is high especially, the good characteristics that service time is very remote.
