Description

[0001] EFFICIENCY ENHANCEMENT EQUIPMENT FOR SOLAR PHOTOVOLTAIC POWER FACILITIES [0002]

The present invention relates to a facility for improving efficiency of a photovoltaic power generation system, and more particularly, to generate an abnormal flow by cooling water and air, and to spray a collision jet of a fluid to improve cooling and cleaning effects while reducing the amount of cooling water used. It relates to an efficiency improving system of a solar power plant.

Generally, the method of using solar energy is divided into a method using solar heat and a method using sunlight. The method of using solar heat is a method of heating and generating electricity by using water heated by the sun, and a method of using sunlight is a method of generating electricity by using sunlight, It is called solar power generation.

Among the above-mentioned methods, photovoltaic power generation is a photovoltaic effect in which a photovoltaic panel having n-type doping on a silicon crystal and pn-junction is irradiated with sunlight to generate an electromotive force due to the photovoltaic energy, To generate electricity.

For this purpose, a solar cell for collecting sunlight, a photovoltaic module as an aggregate of solar cells, and a solar array for uniformly arranging solar cells are required.

For example, when light is incident on the solar module from the outside, electrons in the conduction band of the p-type semiconductor are excited to the valence band by the incident light energy. One electron-hole pair (EHP) is formed inside the p-type semiconductor, and electrons in the electron-hole pair generated are transferred to the n-type semiconductor by an electric field existing between the pn junctions. It passes over and supplies current to the outside.

Unlike existing energy sources such as fossil raw materials, sunlight is a clean energy source that does not have the danger of global warming, such as greenhouse gas emissions, noise, environmental destruction, etc., and there is no fear of depletion. Unlike other types of wind and seawater, solar power generation facilities are free from installation and maintenance costs.

However, in the case of the most widely used silicon solar cell, when the temperature of the photovoltaic module is increased, a power reduction of 0.5% per 1 ° C occurs. According to these characteristics, the output of photovoltaic power is highest in spring and autumn, not the longest summer. Such a temperature rise is a major cause of deteriorating the power generation efficiency of the photovoltaic power generation.

In addition, such a solar module has disadvantages that dust can be easily accumulated on the solar panel due to weather phenomenon such as yellow dust and bad weather. When dirt accumulates on the solar module, the solar module's light absorption rate is significantly lowered, and therefore the power generation efficiency may also be lowered.

In addition, when rain or snow falls on the solar panel in winter, the power generation efficiency may decrease.

In order to prevent deterioration of power generation efficiency due to such dirt, snow, and rain, an efficiency improvement facility (maintenance facility) of a solar power generation facility is used.

In order to improve the efficiency of solar power generation facilities, the cooling module which cools the temperature of the solar module and the cleaning and snow removal of the dirt, snow, rain etc. accumulated on the solar panel, It functions to maintain the solar power generation facilities.

If the cooling effect on the solar module of the efficiency improvement facility of the solar power generation facility is not smooth or the cleaning action of the solar panel is not desired, there is a problem in that the output of the solar module is reduced.

In addition, the efficiency improvement equipment of the photovoltaic power generation equipment is to use a huge amount of water (cooling water, washing water, snow removal water, etc., but functionally referred to as cooling water) for cooling and cleaning the solar module. . Depending on the location, groundwater, tap water, and river water are used as cooling water. In many areas, it is difficult to supply sufficient cooling water, and the electricity used for supplying and spraying the cooling water also reduces the efficiency of the photovoltaic plant as a whole. .

Therefore, there is a need for a proposal for improving the efficiency of a photovoltaic power generation facility that enables efficient cooling and cleaning while reducing the use of cooling water.

In addition, the efficiency improvement equipment of the photovoltaic power generation equipment should ensure the reliability of each component in performing cooling and cleaning with cooling water.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the terminology used herein is for the purpose of description and should not be interpreted as limiting the scope of the present invention.

The embodiments described in the present specification and the configurations shown in the drawings are preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention and thus various equivalents and modifications Can be.

1 is a schematic view for explaining a configuration of an efficiency improvement facility of a solar power generation facility according to the present invention.

Efficiency improvement equipment of the photovoltaic power generation equipment according to the present invention of FIG. 1 includes a storage tank 1, a coolant injection means 6, a coolant supply pipe 5, a pump 25, a valve 20, and a control unit 3. Include.

Cooling water injection means (6) is installed to correspond to each of the solar modules (7) is a means for injecting the coolant to spray the coolant to the solar module (7). If cooling water is poured into the solar module 7 or sprayed weakly, it is difficult to obtain sufficient cooling and cleaning effects. In this embodiment, impingement jets of cooling water are injected into the solar module 7.

The impingement jet has excellent heat and mass transfer effects from the coolant to the impingement surface, thereby improving the cooling and cleaning effect and reducing the generation of scale.

However, in order to generate a collision jet, the speed of the coolant is 30 m / s or more and the pressure is 1.6 kg / cm ² or more, based on the inlet of the coolant spray means 6 for injecting the coolant into the solar module 7. desirable. Here, the inlet of the coolant spray means 6 refers to the end of the coolant spray means 6 into which coolant is injected to the outside.

The cooling water supply pipe 5 serves to deliver the cooling water supplied from the storage tank 1 to the injection means 6 through the pump 25. The cooling water supply pipe 5 is preferably buried in the ground to maintain the temperature of the cooling water.

The pump 25 pumps the cooling water stored in the storage tank 1 to supply the cooling water to the cooling water injection means 6 through the cooling water supply pipe 5, and the valve 20 opens and closes the cooling water supply pipe 5 to spray the cooling water. The means 6 controls the cooling water injection.

The control unit 3 controls the driving unit 9 including the pump 25 and the valve 20 and drives or stops the pump 25 and opens and closes the valve 20.

The manner in which the control unit 3 controls the pump 25 and the valve 20 is not particularly limited, but is preferably designed to maximize the use efficiency of the cooling water. A control method capable of improving the use efficiency of the cooling water will be described as an example.

As a first example, this is a time-based control scheme. Specifically, the control unit 3 determines whether the drive start time, and if the drive start time drive the pump 25, and opens and closes the valve 20 for a set time sequentially. The start time of the driving and the opening time of the valve 20 may be set in consideration of the region of the solar power generation facility and the characteristics of the facility.

Another example is the temperature control method. Specifically, it is determined whether the measured temperature difference between the temperature of the module 7 and the cooling water is equal to or greater than the set temperature difference between the temperature of the module 7 and the cooling water, and the measured temperature difference between the temperature of the module 7 and the cooling water is determined. If the temperature difference between the temperature of the module 7 and the cooling water is greater than or equal to the set value, the pump 25 is driven and the valve 20 is sequentially opened and closed until it is less than that. The temperature difference setting value of the temperature of the module 7 and the cooling water may be set in consideration of the region where the solar power generation facility is installed and the characteristics of the facility.

Whatever control method is selected, it is preferable to measure the pressure in the cooling water supply pipe 5 and to terminate the start of the efficiency improving equipment when the pressure is out of the predetermined pressure range.

If the measured pressure exceeds the maximum value of the set pressure range, a problem such as freezing of the coolant occurs in the coolant supply pipe 5, and if the measured pressure does not reach the minimum value of the set pressure range, the coolant supply pipe Since a problem such as water leakage occurs in (5), start-up is stopped to prevent the failure of the equipment and to efficiently use the cooling water.

In addition, in consideration of the amount of cooling water stored in the storage tank 1 and the supply speed of the cooling water supplied to the storage tank 1, it is preferable to control the injection amount of the cooling water so that the cooling water is properly distributed during the driving time. In this case, the injection amount of the cooling water may be controlled to be sprayed at the same speed every hour, or may be controlled to be sprayed at different time intervals.

Cooling water injecting means 6 according to the present invention is a rotating body and the rotating body to reciprocate left and right by the flow of the cooling water supplied from the cooling water supply means including the storage tank 1, the valve 20 and the pump 25 It includes an injector for generating an abnormal flow by the air flowing into the cooling water supplied through the cooling water and the flow of the cooling water to discharge the fluid having a pulse of the cooling water and the air to the impingement jet.

The injector according to the present invention is composed of an ideal flow generating nozzle for generating two phase flow by introducing air into the cooling water injected by the orifice. The impingement flow, that is, the impingement jet using a mixture of air and water has a much better heat transfer and momentum transfer effect than the impingement jet using only the coolant, thereby improving cooling and cleaning efficiency and reducing the amount of cooling water used.

In addition, the rotor can reciprocately rotate the coolant jetting means 6 through a mechanical mechanism using a flow of coolant without additional power to cool and clean the front surface of the solar module 7 evenly, and greatly increase the operating cost. Can be saved.

The first and second flow holes having different flow paths such that the coolant flowed into the rotating body 100 through the inlet 121 and the flow direction components in opposite directions are formed in the separating plate 200. 210,220 are formed through. That is, the first and second flow holes 210 and 220 are formed such that a direction component, for example, an X-direction component and a -X-direction component, in which the flow directions of the coolant passing therethrough are opposite to each other, is generated. It will be described later.

The rotation aberration 300 is formed in a shape in which a plurality of rotary blades 310 are spaced at equal intervals along the circumferential direction, and the central axis C is inserted into the coupling groove 415 formed in the fixed support shaft 131. And rotatably coupled to each other and disposed adjacent to one side of the separating diaphragm 200 to rotate by the flow force of the coolant passing through the first and second flow holes 210 and 220 of the separating diaphragm 200. It is configured to. The flow direction of the coolant passing through the first and second flow holes 210 and 220 has components opposite to each other as described above, wherein the first and second flow holes 210 and 220 are rotated open / close unit 400 to be described later. The rotation aberration 300 is reciprocally rotated in both directions by the flow force of the coolant having the components in the opposite direction passed through the first flow hole 210 or the second flow hole 220 so as to be alternately opened and closed by.

The rotation opening / closing unit 400 is rotatably mounted inside the rotating body 100 so as to reciprocately rotate in conjunction with the reciprocating rotation of the rotation aberration 300, and alternates the first and second flow holes 210 and 220 according to the rotation. It is configured to open and close with. The rotation opening and closing unit 400 is interlocked with the rotary aberration 300 by a separate link unit 500, the link unit 500 is a variety of ways through a variety of power transmission mechanical elements, such as a plurality of link plates, chains, belts 3 and 4, it may be configured using a plurality of gears.

The injector 60 to be described later is configured to communicate with the internal space of the rotor 100 through the outlet 111 to inject the coolant discharged from the rotor 100. In addition, the injection body 60 is coupled to the rotation opening and closing unit 400 inside the rotating body 100 rotates integrally with the rotation opening and closing unit 400 and injects coolant. Therefore, since the injector 60 rotates and injects coolant, the coolant is evenly sprayed on the entire area of the solar module 7.

According to this structure, the rotating body 100 is supplied with cooling water, and the rotary aberration 300 reciprocally rotates by the flow force of the cooling water alternately passing through the first and second flow holes 210 and 220 so that the upper injection body 60 is rotated.

Next, the mechanism for rotating the injector 60 in both directions according to an embodiment of the present invention will be described in more detail.

As described above, the separating diaphragm 200 is fixed to the inside of the rotating body 100 in a flat shape as described above, and the separating diaphragm 200 has first and second flow holes 210 and 220 formed therein. At least one first and second flow holes 210 and 220 are each formed to have a straight flow path formed to be inclined with respect to the thickness direction of the separating plate 200.

In this case, the inclination directions of the first and second flow holes 210 and 220 may be symmetrically formed with respect to the thickness direction of the separation plate 200. For example, the first flow hole 210 is formed to be inclined to form a coolant flow force for rotating the rotation aberration 300 in a counterclockwise direction with reference to FIG. 6, and the second flow hole 220 is a rotation aberration ( It may be inclined to form a coolant flow force for rotating the clockwise 300.

At this time, the first and second flow holes (210, 220) are each other along the circumferential direction to the separation diaphragm 200 as shown in Figures 6 to 8 for reinforcement of the coolant flow force for rotating the rotary aberration (300) Each of the first and second flow holes 210 and 220 may be formed in alternating positions along the circumferential direction. Dogs and so on will be variously modifiable.

On the other hand, the rotation opening and closing unit 400 is reciprocating in both directions in conjunction with the reciprocating rotation of the rotary aberration 300 and alternately open and close the first and second flow holes (210, 220). Accordingly, the first and second flow holes 210 and 220 are alternately opened and closed by the reciprocating rotation of the rotary opening and closing unit 400, and the coolant flows through the first and second flow holes 210 and 220 alternately. The power has components opposite to each other, so that the rotation aberration 300 reciprocates, and the reciprocation of the rotation aberration 300 again generates a circulation mechanism for reciprocating the rotation opening and closing unit 400. By this circulation mechanism, the reciprocating rotation of the rotary aberration 300 and the rotary opening / closing unit 400 is continuously repeated as long as cooling water is supplied into the rotating body 100.

More specifically, as shown in FIG. 5, when the rotary aberration 300 reciprocates, the circular rotary plate 411 and the connecting sleeve 412 which are directly coupled to the link unit 500 are reciprocated. The injection unit 60 coupled to the connecting sleeve 412 is reciprocally rotated.

In addition, when the connecting sleeve 412 reciprocally rotates, the catching bar 413 extending to the outer side of the connecting sleeve 412 is also reciprocally rotated, in which case the catching bar 413 actuates the engaging plate of the opening / closing clutch unit 430. Since the engaging plate 432 is engaged with the operation locking plate 432 is to reciprocate rotation with the locking bar (413).

When the operation stopping plate 432 reciprocally rotates, the operation plate 431 integrally coupled thereto rotates reciprocally, and the first and second flow holes 210 and 220 alternately according to the reciprocating rotation of the operation plate 431. It is opened and closed. Selective opening and closing of the first and second flow holes 210 and 220 induces reciprocation of the rotation aberration 300 again as described above, and as a result, the rotation opening and closing unit 400 continuously reciprocates.

When the locking bar 413 rotates in the opposite direction while the operation plate 431 closes the second flow hole 220, in this case, the operation locking plate 432 is connected to the locking bar 413. Since the engagement plate 432 and the operation plate 431 do not rotate, the second flow hole 220 is kept closed because it is not engaged.

Therefore, in this case, as shown in FIG. 8, the operating plate 431 is rotated to close the first flow hole 210 by a separate elastic spring 433 for elastically biasing the operating plate 431.

When the female thread is configured in the connecting sleeve 412, the end of the fastening tube 614 may be configured by processing with a male screw.

In addition, the inner diameter of the discharge pipe 616 forming the outlet of the transfer unit is preferably configured to be larger than the inner diameter of the communication pipe 618, so that a step is formed at the boundary between the discharge pipe 616 and the communication pipe 618.

In addition, an outer wall 620 and an inner wall 622 which are separated and extended downward from the bottom surface 613 are formed on the case 612 of the nozzle cap 600, and the outer wall 620 has an outer edge of the case 612. The inner wall 622 forms a reinforcing structure between the outer wall 620 and the fastening tube 114 under the case 612 to form a coupling space 610.

In addition, the upper surface of the discharge pipe 616 forming the outlet of the nozzle cap 600 is formed with a screw portion 626 having a threaded hole 624 penetrating the side wall, the screw hole 624 is screwed to the screw 608 . In this case, the screw 608 supports a fixed state of the air chamber 604 located in the discharge pipe 616.

On the other hand, the orifice 602 is inserted into the conveying hole of the nozzle cap 600, that is, in the communication tube 618 and sprays the coolant flowing through the fastening tube 614 forming the conveying port toward the discharge pipe 616 forming the outlet of the conveying port. Has the function to

For this purpose, the orifice 602 has an annular rim 634 having a diameter larger than the outer diameter of the orifice tube 632 at one end of the orifice tube 632 and the orifice tube 632 in which the hollow is formed and communicates with the orifice tube 632. While having an orifice sphere 636 having a small diameter has a configuration including a discharge portion 638.

The orifice 602 is inserted into the communication tube 618 is fixed so that the annular rim 634 is caught on the step formed between the communication tube 618 and the discharge pipe 616.

Here, the difference in diameter between the hollow of the orifice tube 632 and the orifice sphere 636 is large. Therefore, the cooling water pressurized into the orifice tube 632 is passed through the orifice sphere 636 by the 'Bernoulli' theorem, and the speed increases and the internal pressure decreases.

That is, the orifice 602 directs the coolant to its connected air chamber 604 at high speed and low pressure. Accordingly, the pressure inside the air chamber 604 is lowered.

The orifice 602 may vary in flow rate depending on the size of the orifice sphere 636.

On the other hand, the configuration of the air chamber 604 coupled to the orifice 602 will be described.

The air chamber 604 is partially inserted into the discharge pipe 616, which is the outlet of the transfer port of the nozzle cap 600, and the inserted end thereof is coupled with the orifice 602 and spaced between the inner wall of the discharge pipe 616 of the nozzle cap 600. Has Accordingly, the air chamber 604 is guided along the clearance formed between the coolant injected from the orifice 602 and the discharge pipe 616 of the nozzle cap 600 and its side 644 and the ideal flow of air introduced into the interior of the air chamber 604. It has the function to occur.

The configuration of the air chamber 604 having the above function will be described in more detail.

The air chamber 604 includes a coupling portion 640 coupled to the outlet portion 638 of the orifice 602, a connection portion 642 inserted into an inlet of the injection tip 606, and a coupling portion 640 and the connection portion 642. The side wall 644 having a lower height than the coupling portion 640 and the connecting portion 642 to maintain the clearance between the inner wall of the discharge pipe 616 of the nozzle cap 600 to ensure the inflow of air therebetween, and the clearance And at least one annular rib 648 having an open area 646 formed on the outer surface of the side wall 644 to ensure air inflow. And, the air chamber 604 is a plurality of through holes 650 to ensure that air is introduced into the side wall 644 between the coupling portion 640 and the annular rib 648 closest to the coupling portion 640. Is formed and a part of the side wall 644 is inserted into the discharge pipe 116 of the nozzle cap 100.

As described above, since the air chamber 604 is configured, the clearance between the discharge pipe 616 and the side wall 644 is reduced by the coolant injected at a high speed and low pressure from the orifice 602 and the low pressure therein. An abnormal flow of air introduced through the open region 646 and the through hole 650 of the annular rib 648 occurs.

That is, a fluid mixed with air and coolant by the abnormal flow generated in the air chamber 604 is provided to the injection tip 606, where the fluid has a pulse by the abnormal flow and the frequency of the pulse is the through hole 650. It can be adjusted by the variable number of the air inflow is adjustable by varying the size of the through-hole 650. The pulse of the fluid due to the abnormal flow is increased by reducing the number of through holes 650 and is lowered by increasing the number of through holes. In addition, the amount of inflow of air increases when the size of the through hole 650 increases, and decreases when the size of the through hole 650 is reduced.

Meanwhile, as described above, the fluid in which the coolant and the air are mixed by the abnormal flow generated in the air chamber 604 proceeds to the injection tip 606 and may be injected into the collision jet through the injection tip 606.

Here, the injection tip 606 may be detachably coupled to the end exposed to the outside of the discharge pipe 616 of the nozzle cap 600 of the air chamber 604, the injection tip 606 and the discharge pipe 616 It is coupled to maintain the separation interval and the combination of the injection tip 606 as described above ensures that the air can be introduced into the spaced space between the air chamber 604 and the discharge pipe 616.

The injection tip 606 has a shape in which the injection inlet 652 and the injection outlet 654 communicate with each other and narrow toward the injection outlet 654 at a predetermined inclination angle. The angle of inclination narrowing toward the injection outlet 654 may determine the angle of injection of the fluid. The connecting portion 642 of the air chamber 604, which is coupled with the injection inlet 652 of the injection tip 606, may be formed of a plurality of protrusions sufficient to obtain a supporting force for engagement with the inner wall of the injection inlet 652. Can be.

The injection angle corresponds to the extent to which the impingement jet is injected at the injection outlet 654 of the injection tip 606. The abnormal flow generating nozzle according to the present invention may change the injection angle of the fluid jet by changing the injection tip 606 that is detachably configured to vary the injection angle of the collision jet according to the object to be cooled and cleaned.

Accordingly, the fluid with pulses propagating from the air chamber 604 enters the injection tip 606 through the injection inlet 652 and is injected through the injection outlet 654 with a collision jet having a particular injection angle.

9 to 13, the injector 60 according to the present invention may be implemented. Referring to FIG. 14, an abnormal flow of coolant and air in the injector 60 and impingement jetting of the fluid will be described. do.

Cooling water pressurized and supplied from the connecting sleeve 412 of the rotation opening / closing unit 400 flows in as shown by arrow A1 through the fastening pipe 614 of the nozzle cap 600, and the coolant is connected to the fastening pipe 614. After moving to 618, it flows into the orifice tube 632 of the orifice 602 as shown by arrow A2, and then passes through the orifice port 636 as shown in Table A3 and is discharged into the air chamber 604 at high speed and low pressure. .

As described above, as the coolant is discharged into the air chamber 604 through the orifice 602, a low pressure is formed in the air chamber 604. Accordingly, air flows along the side wall of the air chamber 604 as shown by arrow A4 and air flows inside as shown by arrow A5 through the through hole 650 formed in the side wall 644 of the air chamber 604.

As a result, an abnormal flow of the coolant and the air is generated in the air chamber 604. As a result, the fluid having a pulse is injected through the injection tip 606 as the arrow A6 into the impinging jet as the coolant and the air are mixed.

As described above, in the present invention, since an abnormal flow occurs in the nozzle, a component to which a fluid caused by the abnormal flow is affected can be minimized. That is, it does not affect the parts (aberration, etc.) for supplying the cooling water by pressurizing, that is, the parts of the rotating body 100 formed before the fastening pipe 114 of the nozzle cap 100, so that the life of the parts can be guaranteed. As a result, the reliability of the installation can be secured.

In a general case, the impingement jet may be injected as shown in FIG. 15, but the impingement jet according to the abnormal flow of the present invention has a spraying shape by pulse as shown in FIG. 16.

As illustrated in FIG. 16, the collision jet injected by the embodiment according to the present invention increases the heat transfer coefficient as the pulsation frequency increases during the collision injection. Therefore, the cooling and cleaning effect can be increased.

In addition, according to the present invention, since the air is abnormally flowed together and mixed in the fluid, the amount of cooling water used may be reduced by that amount.
