Description

The dish formula of adjustable focus ratio focuses device

Technical field

The invention belongs to solar energy heat utilization field, specially refer to the dish formula beam condensing unit of fixed-focus.

Background technology

In solar energy heat utilization field, because the ray density of the sun is too low, seek out higher temperature, must use solar-energy light collector.At present, solar-energy light collector roughly has three kinds: the one, and numerous plane mirrors are superimposed the hot spot that is reflected, to strengthen the density of light, like tower generating equipment.Its advantage is: be fixed on certain position to focus, be convenient to the utilization of photo-thermal.Shortcoming is: sunlight is very big to the varies with cosine of plane mirror, causes facula area greatly different in size, and the thermal efficiency is low; In order to reduce the influence that varies with cosine is brought, have to tower build very high, a hundred or so easily rice has strengthened investment, still overcome not the influence that the cosine effect is brought, so efficient is lower.Up to the present this be, also do not enter into the main cause in market.In addition, tower concentrating device, what lean on is the heliostat field of plurality of cells, achieves the goal, and can only large enterprise use, general family can't use.The 2nd, the slot light collection device.Condenser belongs to parabola translation gained minute surface.Advantage is: varies with cosine is less relatively, and thermal efficiency ratio is tower to increase.Shortcoming is: focus is not concentrated and is a line style, generally obtains middle temperature only; In addition, focal line also changes with the change of the angle of pitch, utilizes range limited system.The 3rd, dish formula condenser.Reflecting surface rotates gained by parabola.Advantage is: through following the tracks of the sun, and the vertical all the time sunlight of light plane and do not have varies with cosine, focus is concentrated, thereby focuses on than big, can obtain high temperature, and is most effective.Shortcoming is: focus is to follow the rotation of the sun to rotate with speculum, inconvenient solar thermal utilization.So, the research of the beam condensing unit of many fixed-focuses has appearred again at present.The handlebar minute surface is designed to two-way variable curvature, digital technology high order curved surface, or the like, numerous, mostly obtained effect preferably.But all these; A common weak point is arranged again; Promptly because condenser and focus are discrete, condenser mirror can not vertical at any time sunlight, so still can not overcome the cosine effect; The present reality that exists of helioplant field that Here it is: be the condenser of the various fixed-focuses of representative promptly, fixed focus but do not solve the cosine problem with tower; And dish formula condenser does not have the cosine problem, but focus can not be fixed.

In addition, in this field, up to the present; The problem that also has everybody all seldom to relate to: because the precision of condenser, and fix, therefore with the distance of thermoreceptor; Focus on and to fix than also, the facula area that obtains on the thermoreceptor be fix (refer to dish formula condenser.Other condensers are not if consider the cosine problem, and facula area is also fixed).But the sun is under the situation of the different weather of different time (early, middle and late) (like fine day, cloudy etc.), and intensity of illumination also is different; Therefore, the temperature that thermoreceptor can reach also is different, and this just makes many devices, particularly utilizes solar energy to produce the device of high temperature; Utilization ratio is very low, at noon the period, utilizes under the reasonable situation of sunlight, and all the other times; Because of the sunray insufficient strength, hot spot does not reach temperature required, and can't utilize.

Summary of the invention

The objective of the invention is; Invent a kind of new beam condensing unit; Getting dish formula condenser does not have the advantage of cosine effect constantly over against the sun, overcome the unfixed defective of its focus, just gets the tower advantage that waits the beam condensing unit of some fixed-focuses; Hot spot is fixed on certain position, and overcomes the shortcoming of falling them and can not overcoming the cosine effect.

A purpose is again, and the focusing that general condenser is fixing is more adjustable than becoming, and promptly according to sun intensity variations, changes the area of institute's optically focused spot at any time, and is temperature required to obtain at any time.

Technical scheme

Dish formula condenser is under the control of tracking system, and its primary optical axis is parallel with sunray all the time, and though the sun where the position; Dish formula condenser primary optical axis place straight line all passes through dish formula condenser for following the tracks of the pivot that the sun rotates, and this center is; Follow the intersection point of the horizontal cross shaft of comprehensive vertical vertical pivot and following in elevation in the orientation; Be fixed,, be located at pivot photothermy point (promptly receiving optical thermal device).

The pivot of dish formula condenser generally is located at two zones, promptly near the dish formula condenser summit and near the focus, in theory; Pivot is located at any position of primary optical axis place straight line, and this straight line all passes through this center, still, if be located between the summit and focus of dish formula condenser; Can cause interference to light path, the support of pivot is also bad to be set up, so generally be not located at this section zone; If it is too far away that pivot is located at beyond summit or the focus, can cause then that resistance arm is long to cause unnecessary power loss, also can take too many space in addition; Cause unnecessary waste, thus, be located near summit or the focus; Be meant generally beyond summit or the focus to be as the criterion with the support mutually noninterfere when rotating that this is the preferred embodiments of general needs nearby with dish formula condenser.

When pivot was located at apex region, dish formula condenser turned round between the pivot and the sun and with sun synchronization; When pivot was located at the focal area, the dish formula condenser and the sun be in the pivot both sides, and turn round relatively with the sun.

Near certain position dish formula condenser focus; Put a light path adjuster, so-called light path adjuster is exactly in its tubular framework; Be equipped with optical mirror slip; Primary optical axis is vertical with optical mirror plane and pass the optical mirror slip center, and optical mirror slip can be adorned a micro motor as moving power along the primary optical axis move left and right on the framework on framework.

When pivot during in apex region; Optical mirror slip on the light path adjuster is concave mirror or convex mirror, before the light path adjuster is located at focus; Be between focus and the summit; Optical mirror slip on the light path adjuster is a convex reflecting mirror, and when the light path adjuster was located at after the focus, the optical mirror slip on it was a concave mirror.

When pivot was located at the focal area, the optical mirror slip on the light path adjuster was concavees lens or convex lens, and before the light path adjuster was located at focus, the optical mirror slip on it was concavees lens, and when the light path adjuster was located at after the focus, the optical mirror slip on it was convex lens.Certain position was meant near what is called was located at focus with the light path adjuster: no matter the light path adjuster is located at before or after the focus, the initial position of the optical mirror slip on it is that the focus of optical mirror slip or virtual focus overlap with the focus of dish formula condenser.

Because the optical mirror slip plane is vertical with primary optical axis, so the optical mirror slip on the light path adjuster; Just with primary optical axis reflection or be transmitted on the photothermy point that is located at pivot, when the focus of the optical mirror slip on the light path adjuster overlaps with the focus of dish formula condenser, through optical mirror slip reflect or transmission to be centered around the axial light beam of key light be a branch of directional light; This bundle directional light just can impinge upon on the photothermy point of being located at pivot, adjusts the distance of optical mirror slip and dish formula condenser focus, be centered around that light on the primary optical axis just can change and primary optical axis between angle; Become scattered beam or assemble light beam by collimated light beam; When light beam becomes scattered beam, the facula area that on photothermy point, forms, the facula area that forms than collimated light beam is big; Focus on this moment than having diminished; When collimated light beam became the gathering light beam, the facula area that on photothermy point, forms was just little, and the focusing of this moment is than becoming big.

Certainly, in the time of near pivot is located at the summit, place, dish formula condenser summit will open a circular hole, and the circular hole size can be through being as the criterion with required maximum area hot spot.

How to adjust facula area as for optical mirror slip, existing is the example explanation with the convex reflecting mirror.Because of the angle of the normal of convex reflecting mirror incidence point and primary optical axis is that center by convex reflecting mirror increases to the edge gradually; When the virtual focus of convex reflecting mirror overlaps with the focus of dish formula condenser; The incident ray of certain angle impinges upon on the incidence point of convex reflecting mirror, and the light that reflection is come out is parallel with primary optical axis.As with convex reflecting mirror to dish formula condenser focus near; This moment, the light of certain incident angle just can impinge upon former incidence point with interior place, and the normal of this point and the angle of primary optical axis are littler than the angle of the normal at former incidence point place and primary optical axis, because of the angle of incident ray and primary optical axis does not become; So this moment, incidence angle was just big than original incidence angle; Thereby angle of reflection is also big, so reverberation just can depart to primary optical axis, thereby can form convergent beam.Otherwise,, the focal length of convex reflecting mirror and dish formula condenser is strengthened when convex reflecting mirror moves to dish formula condenser zenith directions; The light of certain angle incident this moment just can impinge upon the place at convex reflecting mirror edge; The normal of this incidence point and the angle of primary optical axis are bigger than the angle of the normal of former parallel light beam incidence point and primary optical axis, and incident angle of light is constant, thereby incidence angle has diminished; Angle of reflection is also just little, and the reverberation of this moment just can depart from and formerly be parallel to primary optical axis and outwards scattering.The principle of other optical mirror slip zoom similarly.

To be located at the support of apex region or focal area be different to pivot in addition.Because when being located at apex region; The sun is male and fomale(M&F) speculum two secondary reflections through dish formula condenser and light path adjuster, does not change so impinge upon the radiation direction of pivot at last, and is still consistent with sun direction of light; Down shine from the top; Therefore the pivot support can be designed as vertical tubular support, and can on the base of its lower end, rotate, so as dish formula condenser on the orientation to the tracking of the sun.Diameter place, horizontal cross-section, tubular support upper end, there are two spindle nose fulcrums in the barrel outside, and dish formula condenser summit stent support makes dish formula condenser on its fulcrum, do elevating movement, to follow the tracks of the elevation angle of the sun on it.Because pivot is located at the vertical vertical pivot of orientation tracking and the intersection point of the horizontal cross shaft that elevation angle is followed the tracks of; It is center, horizontal cross-section, tubular support upper end; It is fixed above that the photothermy point is established; In order not interfere support, therefore support is designed to tubular because of carrying out the rotation that the orientation tracking needs.

When pivot is located at the focal area; Sunlight is through the condenser primary event of dish formula with through a transmission of the optical mirror slip on the light path adjuster, and radiation direction changes, when the sun during in the sky; Dish formula condenser below light is reflexed on the photothermy point of pivot; At this moment support should be tiltedly upright at meridian plane, and its angle is as the criterion with its dish formula condenser that forwards the pivot below relatively to not interfere when sun transit time.

The present invention is because with dish formula condenser reception sunlight, thereby do not have the cosine effect; Be provided with the light path adjuster, and focus is fixed on pivot, and adjustable lay the grain spot size, so efficient is high, purposes is wide.At the different photo-thermal receiver of pivot photothermy point place configuration, just have different purposes: dynamical in photothermy point placement, can accept the solar panel of high-strength sunshine, just can generate electricity, efficient can reach more than 30 percent; If place pot and stove, be solar cooker at photothermy point; Placing boiler, is solar furnace, focuses on ratio because device of the present invention can be adjusted, and therefore, solar furnace also can temperature adjustment.

But temperature adjustment solar furnace: on the photothermy point of dish formula condenser pivot, put a spherical thermoreceptor, heat-conducting medium is arranged in the thermoreceptor; Lead to heat-storing device or directly towards using hot device, heat-conducting medium is driven by heat pump, on spherical thermoreceptor by pipeline; Temperature sensing device is arranged, and when temperature was undesirable in the thermoreceptor, temperature controller started the micro motor on the light path adjuster; The distance of adjustment optical mirror slip and dish formula condenser focus focuses on ratio with adjustment, makes the facula area increase on the thermoreceptor or dwindles; And control adjustment heat pump flow velocity simultaneously or successively, to adjust the time that heat-conducting medium stops in spherical thermoreceptor.After being set as required, the temperature of the heat-conducting medium in the spherical thermoreceptor just can obtain a relatively stationary temperature and overcome the strong and weak variation of sunshine to Influence of Temperature.

Because the heat-conducting medium in the spherical thermoreceptor is flowable, therefore the volume of spherical thermoreceptor is just programmable smaller.So also reduced thermal loss.In order further to reduce thermal loss; Fixing or movable heat-barrier coating is housed on spherical thermoreceptor;, move the place that can shine at hot spot and load onto movable thermal insulation layer all with fixing thermal insulation layer protection in sunless place, its movable part moves on the sphere of spherical thermoreceptor with hot spot; Promptly except that the hot spot porch, remainder is all protected by thermal insulation layer.

Because the constant temperature solar furnace adds heat-storing device; Just for no matter people provide a day and night, (general heat-storing device can keep the temperature couple of days to fine cloudy even cloudy raining; So so long as not cloudy weather for several days running weather) thermal source that can utilize, this thermal source can be used for heating up water, cook, warm oneself, freezing or the like.If but numerous temperature adjustment solar furnace individualities are lined up heat-storing device of the common use of matrix, or use one jointly directly with thermic devices and a heat-storing device, just can obtain a large amount of heats, to supply the large-scale hot equipment of using.Enterprise can be used to oven dry, desalinizes seawater etc., particularly is used for building the solar thermal energy power station, will replace solar power tower.Because of the thermal efficiency of solar power tower only about 60%; And the efficient of gas-turbine is at 20%-30%; Gross efficiency can only reach tens percent in theory, and the used dish formula of the present invention condenser thermal efficiency is more than 85%, thereby generating efficiency can reach twenties percent.Construction cost also can descend in addition: because of generally beam condensing unit is for obtaining higher temperature, it is very big that single condenser area is all made, and big reaches up to a hundred square metres; Little also has tens square metres, and for resisting wind-force, rigid structure becomes progression to increase with the small-sized condenser rigid body of material than several square metres with material; And the present invention recently increases temperature with adjustment focusing; Thereby single condenser area is only at several square metres, and unit are significantly reduces with material like this, thereby the cost reduction; Use this device also need not build high tower simultaneously, therefore also reduced cost; In addition, raise the efficiency the also corresponding reduction of cost.
