Description
Technical field
The present invention relates to technical field of solar utilization technique, be specifically related to a kind of linear Fresnel transmission-type molten salt energy-storage and utilize system.
Background technology
Traditional fire coal, as the energy, can bring carbon dioxide after burning, sulfide, nitrogen oxide, the pollution of the pollutants such as dust, can cause and cause irremediable impact to environment.Most Heavy air pollution attacks capital from the beginning of this year.On November 30th, 2015, the orange early warning of first haze in this year is issued in Beijing's upgrading, and PM2.5 concentration in the whole city increased nearly 10 times in 12 hours, and indivedual website peak concentration presses on towards 1000 micrograms/cubic meter.Be not only Beijing, there is heavily contaminated synoptic process on a large scale in whole Jing-jin-ji region and surrounding area, pollution range constantly expands from night November 26.From observation data, with the material such as coal fire discharged directly related organic matter, sulfate, black wood charcoal, be the main constituent of PM2.5, also demonstrating that coal pollutes is the primary source causing this North China air heavily contaminated on a large scale.My unit now develops solar utilization technique, to replace traditional fire coal.
Fresnel Lenses (Fresnellens), have another name called Fresnel lens, mostly be the thin slice being noted pressure by polyolefine material, also glass is had to make, lens surface one side is light face, the ascending concentric circles of another side imprinting, its texture to penetrate according to the interference of light and disturbing and relative sensitivity and receiving angle require to design.The requirement of lens is very high.The necessary any surface finish of lens of a slice high-quality, clean mark, its thickness becomes with purposes, and how at about 1mm, characteristic is that area is large, thickness is thin and detecting distance.Fresnel Lenses to be many times equivalent to the convex lens of infrared ray and visible ray as shown in Figure 2, and effect is better, but cost is more much lower than common convex lens.Being used for required precision is not very high occasion, as slide projector, film magnifying glass, Infrared Detectors etc.
Use common convex lens, there will be the phenomenon that corner is dimmed, fuzzy, this is because the refraction of light only occurs in the interface of medium, convex lens sheet is thicker, and the part of light straightline propagation in glass can make light attenuation.If the part of straightline propagation can be removed, only retain the curved surface that refraction occurs, just can save the spotlight effect that lot of materials reaches identical simultaneously.Fresnel lens adopts this principle.Fresnel Lenses looks but can reach the effect of convex lens by the glass having countless multiple concentric circles lines (i.e. Fresnel zone) as a slice, if projection source is directional light, can keep the consistent of image brightness throughout after converging projection.
Fresnel Lenses utilizes the special optical principle of lens, and side produces " blind area " and " highly sensitive district " alternately changed before the detectors, to improve its detection receiving sensitivity.Out-of-date when there being people to walk before lens, the infrared ray that human body sends just constantly alternately enters in " highly sensitive district " from " blind area ", so just makes the infrared signal received input with dynamic impulse form, thus its energy amplitude by force.
Fresnel Lenses effect has two: one to be focussing force, infrared signal refraction (reflection) is released on PIR by heat, second effect will be divided into several area pellucidas and dark space in search coverage, and the motive objects physical efficiency making to enter search coverage releases infrared signal with the form of the variations in temperature heat that changes on PIR.
