The of the present invention structure expressed as Fig. 1, Fig. 2, the present invention is a kind of pressure accumulation water system, comprises water tank, user side 9, the tank body of water tank is provided with water inlet 6 and delivery port 8.
In order to solve the problem that exists at the described present known technology of this manual background technology part and to overcome its defective, realize the users' that live scattered such as rural area or mountain area water supply, and accomplish economy, suitable goal of the invention that the technical scheme that the present invention takes is:
As shown in Figure 1 and Figure 2, this pressure accumulation water system provided by the present invention, water tank wherein is a pressure water storage tank 7, its tank body is withstand voltage hermetically-sealed construction; In this water supply installation, also be provided with air compressor 4, hold atmospheric pressure jar 5, the described tank body that holds atmospheric pressure jar 5 also is withstand voltage hermetically-sealed construction; Air compressor 4 provides compressed air to holding atmospheric pressure jar 5; Hold atmospheric pressure jar 5 and pass through pipeline connection with pressure water storage tank 7.
According to the water supply characteristics of rural area, mountain area unshared housing, with the top rural area that provides, hillman user water supply installation and solar powered power consumption and the water supply problem of solving.
Its operating principle is:
The electromagnetic valve of control " pressure accumulation " jar is opened, and gives water-filled pressure water storage tank 7 pressurizations, and air pressurized has just been arranged in the pressure water storage tank 7, and peasant household's water system has just had the power that supplies water, and the user opens the just water outlet automatically of water tap of user side 9; After treating that water has been used up in the pressure water storage tank 7, carry out next working cycles again, the work of water supply installation repetitive cycling;
In the rural area of using solar energy " pressure accumulation ", hillman user water supply installation, it is first key point that the present invention need solve that pressure of supply water is provided, and how the water transport that will need to use with minimum energy is delivered on the hillside of living in dispersion peasant household other is the topmost purpose that the present invention will realize.
According to the specific rule of boyle-Ma Luo in the physics:
P
1V
1＝P
2V
2
P wherein
1-pressure 1, V
1-volume 1; P
2-pressure 2, V
2-volume 2.
From Bo-Ma law as can be seen, the Compressed Gas of certain mass is the basis of pressure water supply equipment operate as normal, just can satisfy the water supply requirement of peasant household if can in a pressurized tank, pressurize, it is than separately with the water pump water supply and energy saving that pressurizes, and can more easily improve the height that supplies water, can save many power consumptions, in rural area by solar energy " pressure accumulation ", in the water supply installation test of mountain area, give 1 kilogram of pressure air pressure of the every increase of pressurized tank, the freeboard of device just can be brought up to 10 meters, this is hydromechanical basic principle, and promptly the pressure of liquid increases with the degree of depth; In the same degree of depth, the pressure of liquid on all directions equates; The pressure of different liquids is also with the relevant knowledge of density.It is as follows with the design formulas of height that it calculates liquid pressure:
P＝ρgh
ρ is a fluid density in the formula, and unit is a kilogram/rice
3G is an acceleration of gravity, g=9.8 ox/kilogram; H is the degree of depth in somewhere in the liquid, and unit is a rice; P is a liquid pressure, and unit is a handkerchief.
By formula P=ρ gh as can be known, the pressure of liquid size is only relevant with density of liquid ρ, degree of depth h and acceleration of gravity, all has nothing to do with other factors such as liquid volume, container shapes, floor space sizes.Also can be summarized by formula P=ρ gh: when fluid density ρ one timing, promptly in a kind of liquid, the pressure P of liquid is directly proportional with degree of depth h; In different liquid, when degree of depth h was identical, the pressure p of liquid was directly proportional with fluid density ρ, so with rural area, the mountain area water supply installation of solar energy " pressure accumulation ", its water supply highly increases and improves along with pressurized tank pressure.
If just do not reach above-mentioned freeboard with same power water pump, this is because piston type water pumper or centrifugal water pump all utilize atmospheric pressure to come work.When common water pumper was worked, it drew water highly about about 10 meters, and this is that the step water supply irrigation system common in the rural area is exactly this reason because 1 standard atmospheric pressure approximately can be supported 10.13 meters high water columns.Can reach designing requirement if increase pump power or adopt multistage pump to supply water, but this does not meet the requirement of mountainous rural area peasant household water supply to energy conservation yet.
From following table, can find out the contrast of the freeboard and the power consumption experimental data of water pump and air compressor machine:
Table 1: gas pressure and freeboard and power consumption experimental data statistics.
| Sequence number | Title | Power (W) | Pressuring method | Pressure values (MPa) | Power consumption (degree) | Freeboard (rice) |
| 1 | Water pump | 150 | Gas-liquid mixed | 0.1 | 0.16 | 8 |
| 2 | Air compressor machine | 125 | Compressed air | 0.1 | 0.11 | 9.8 |
| 3 | Water pump | 150 | Gas-liquid mixed | 0.2 | 0.33 | 15.8 |
| 4 | Air compressor machine | 125 | Compressed air | 0.2 | 0.16 | 18.2 |
| 5 | Water pump | 150 | Gas-liquid mixed | 0.3 | 1.2 | 22.5 |
| 6 | Air compressor machine | 125 | Compressed air | 0.3 | 0.34 | 28.2 |
Annotate:
Special excessive when load, stall appearred in motor when water pump continued pressurization, and electric current sharply increases, and must shut down this moment, otherwise motor will be burnt.And the 125W air compressor machine can also continue pressurization, and along with pressure increases the safe pressure-bearing value 1.5MPa that can reach pressurized tank, this moment, the air compressor machine power consumption did not enlarge markedly.
In this, just distinguish the gas-vapor mix water intake mode that the city water pump draws water, both compare and have saved a part of electric energy.
The connected mode of pressure accumulation water system is:
Holding atmospheric pressure jar 5 and the pipeline that pressure water storage tank 7 is connected, is to connect in the upper end of pressure water storage tank 7; Pressure water storage tank 7 is connected with user side 9 by delivery port 8, and delivery port 8 is located at the lower end of pressure water storage tank 7.
Above-mentioned connected mode makes the compressed air that holds atmospheric pressure jar 5 enter the top of the inner chamber of pressure water storage tank 7; And delivery port 8 remains under the water surface, guarantees to have water output.
In order to prevent compressed-air actuated refluence, take following mode:
Described air compressor 4 is provided with one way valve with holding the pipeline that atmospheric pressure jar 5 is connected, and its conducting direction is to holding atmospheric pressure jar 5 from air compressor 4; Described holding on atmospheric pressure jar 5 and the pipeline that pressure water storage tank 7 is connected is provided with one way valve, and its conducting direction is from holding atmospheric pressure jar 5 to pressure water storage tank 7.
In case air compressor 4 decompressions (as outage) or pressure reduce, said structure guarantees that compressed air can not flow backwards, and promptly flows to air compressor 4 from holding atmospheric pressure jar 5; Equally, in case hold atmospheric pressure jar 5 decompressions or pressure reduction, the compressed air in the pressure water storage tank 7 also can not flow backwards to holding atmospheric pressure jar 5.
Described pressure water storage tank 7 is immersed in the water source, and its water inlet 6 is lower than the horizontal plane at water source.
The water inlet of pressure water storage tank 7 is immersed in the water, utilizes the atmospheric pressure principle to intake automatically, to reach the purpose of the not power consumption of fetching water.
Entering water electromagnetic valve is controlled water inlet automatically according to the water needs, get rid of the pressure air that the water inlet of pressure water storage tank 7 internal causes produces, after treating that water is full of pressurized tank, entering water electromagnetic valve and emptying solenoid valve are closed simultaneously, this moment the pressurized tank complete closed, isolated with ambient atmosphere, its inner chamber is remained on treat artesian condition.
Consider the characteristics in mountain area, rural area, " the pressurized tank water cellar " that can make an energy pressure-bearing with cement with it be placed on the rural area water head site below, like this, the one, can be anticorrosion over a long time, exempt maintenance cost; The 2nd, draw materials easily in the rural area, easily realize, gear to actual circumstances.The stainless steel pressure jar that general liquid gas storage tank and city high rise building water system adopt or the carbon steel pressurized tank of enamel coating, with these two kinds of pressurized tanks that material is made, material cost itself is just very high, it is placed on expenses such as the rural area water head site is anticorrosion, maintenance and all can brings no small economic pressures to hill farmer, actual from mountainous rural area economy,, manage to reduce cost during in design, have to equal popularizing of this technology with mountain village, the peasant household water supply installation of solar energy " pressure accumulation ".
In order to add entry, and require energy conservation, structure and method below having taked to pressure water storage tank 7:
Also be provided with the air evacuation port on the described pressure water storage tank 7, be communicated with atmosphere; Described water inlet 6 is communicated with the water source, on water inlet 6 and air evacuation port, is equipped with the electromagnetic valve of self-retaining, and the electromagnetic valve that wherein is located at water inlet 6 places is an entering water electromagnetic valve, and the electromagnetic valve that is located at air evacuation port place is the air emptying solenoid valve.
Because the operating principle of rural area, hillman user water supply installation is different from the mode of operation of the full-automatic building water supply system in city, its energy-conservation reason is, the electric energy that rural area, farmers in mountain area water supply installation are consumed mainly is air compressor 4 and electromagnetic valve, air compressor 4 consumes certain electric energy when producing compressed air, be exactly that electromagnetic valve will consume certain electric energy in addition.What electromagnetic valve adopted is self-holding electromagnetic valve, and it only relies on spring and mechanical localization mechanism to keep the relevant position only in the moment electricity consumption of connecting and closing when being in connection and closed condition, so not power consumption, therefore also just economize on electricity.Mechanical localization mechanism is generally steel ball and reaches deciding groove.
Differ bigger with the air compressor of power and water pump comparing aspect the height that supplies water, the pressure air that the every generation of air compressor is one kilogram, intrasystem water supply height can improve 10 meters, and this is because pressure air has elastic acting force, and can transmit pressure in certain space.Although the water pump pressurization also produces the gas-vapor mix body in " full-automatic building water supply " equipment, but gas is compared with the space that water occupies, the gas compartment is smaller, the finite volume that pressed gas expands, compare with special gas pressurized tank " pressure accumulation ", rural area with solar energy " pressure accumulation ", hillman user water supply installation, the potential energy of water is carried De Genggao, and water pump water supply is not under equal conditions accomplished, must strengthen pump power, this is the higher reason of mountain village peasant household water cost exactly, and with the rural area of solar energy " pressure accumulation ", the power of mountain area water supply installation is that solar cell power generation system is distinguished the urban water supply electricity consumption again, so both contrasts are also just energy-conservation.
In order to realize the purpose of energy-saving and environmental protection, the power source of described pressure accumulation water system is a sun-generated electric power, and its structure is: establish solar panel 1 and battery 2, connected to battery 2 chargings by circuit by solar panel 1; Battery 2 is by being connected with described air compressor 4 and to its power supply.
Because the sunlight resource has dispersiveness, and be available anywhere, solar cell power generation system is particularly suitable for using as independent current source, as village and family expenses electric power system, solar cell illuminator, solar cell water pump system and the solar communications power-supply system etc. of outlying areas without electricity.Solar cell power generation system can also be formed mixed power supply system with other electricity generation systems, as light-wind hybrid power system, light-wind-biogas hybrid power system etc.Because the cost of wind generator system is low, wind energy and solar energy resources have complementarity in many areas, can significantly reduce the capacity of battery again, reduce use cost, so light-wind hybrid power system are applied in many areas.Solar cell power generation system can also link with electrical network, constitutes grid-connected system.Grid-connected system is to convert the direct current that solar cell power generation system sends to alternating current by combining inverter to be connected to the grid.Can also be as required at any time with solar cell power generation system and people or withdraw from electrical network.
In the water supply installation in the present invention, just use solar battery power with natural energy " pressure accumulation ".Solar energy is the environment-friendly and green energy, in daily life, often uses the device of solar energy power generating, and its principle is a photovoltaic effect.When sunshine (or other light) when shining on the solar cell, battery absorbs luminous energy, and it is right to produce light induced electron-hole.Under the effect of battery built in field, light induced electron and hole are separated, and the accumulation of positive and negative electric charge appears in the battery two ends, promptly produce " photovoltage ", and just " photovoltaic effect " also is " photoelectric effect ".If at the both sides of built in field extraction electrode and connect load, then load just has " photogenerated current " to flow through, thereby obtains power output.Like this, the luminous energy of the sun just directly has been transformed into the electric energy that can be put to practicality.
As shown in Figure 2, in the mountain village peasant household water supply installation of solar energy " pressure accumulation ", independent photovoltaic power generation system is the acquisition system of natural energy, generally partly is made up of solar cell array, batteries, controller 10 and inverter 3 etc.Controller 10 is realized the switching of AC and DC loads, can also realize solar energy-electric energy being incorporated into the power networks and moving back the flexible switching of net to electrical network.
The silicon solar cell design scheme:
Silicon solar cell is commercial at present 3 types, i.e. monocrystaline silicon solar cell, polysilicon solar cell and non-crystal silicon solar cell:
Monocrystaline silicon solar cell causes material cost relatively more expensive because employed single crystal silicon material has identical quality with the employed material of semi-conductor industry;
The no regularity of the crystallographic direction of polysilicon solar cell, mean that positive and negative charge is to can not all being separated by the PN junction electric field, because positive and negative charge is to possible owing to the irregular of crystal loses, so the efficient of polysilicon solar cell is generally low slightly than monocrystaline silicon solar cell on the border between crystal and the crystal; But polysilicon solar cell can be with the method production of casting, so its cost of production is lower than monocrystaline silicon solar cell;
Non-crystal silicon solar cell belongs to hull cell, and is cheap, but photoelectric transformation efficiency is lower, and declines under illumination and fall, and is used for low light level power supply at present, as wrist-watch, calculator etc. more; A solar cell can only produce about 0.45V voltage in silicon solar cell, far below the needed voltage of practical application.
In order to satisfy the needs of practical application, must connect into assembly to solar cell.Solar module comprises the solar cell of some, and these solar cells connect by lead.A common solar module approximately can produce the voltage of 16V, just in time can effectively charge for the battery that a rated voltage is 12V.When single component can not satisfy the voltage and current requirement, can form solar cell array to a plurality of assemblies, so just can obtain needed voltage and current.The characteristics sparsely populated in conjunction with hill farmer and economic capability is more weak can be considered to concentrate when building solar power station to build, can manage concentratedly like this, and power supply respectively, it is just lower to apportion other expense of each household, and the peasant easily accepts.
Solar cell power determine and the solar cell array design in, at first be that solar cell power is determined:
1) ask the average peak sunshine duration:
Will be over the years day total radiation mWh/cm of the unit of changing on the average tilt square formation month by month
2, divided by standard day solar irradiance, being average peak sunshine duration Tm, its calculating formula is Tm=It+/100
2) determine the square formation operating current:
The minimum current that square formation should be exported is:
Imin＝Q/Tmn
1n
2n
3
In the formula: Q is load total power consumption every day; n
1Be charge in batteries efficient; n
2For covering or the aging correction factor that causes common desirable 0.9～0.95 owing to dustiness in the square formation surface; n
3Be square formation assembling loss and correction factor that maximum power point is departed from, usually desirable 0.9～0.95.
3) determine the square formation operating voltage:
The output of the operating voltage of square formation should be enough big, can be to guarantee the whole year effectively to charge in batteries, so the operating voltage of square formation in any season must satisfy following equation:
U＝Uf+Ud+Ui
Uf is the battery float charge voltage; The pressure drop of Ud for causing because of blocking diode and the loss of circuit direct current; Ui is the pressure drop that temperature raises and causes.
4) determine square formation power:
N=recommended current (I) * optimum operating voltage (U)
5) accumulator capacity is determined:
The accumulator capacity optimum value is definite in the system, must take all factors into consideration the efficient of solar cell array generated energy, load capacity and inverter etc., and accumulator capacity can be calculated by following formula:
C＝DFP0/LUKa
In the formula: C is accumulator capacity kWh; D for the longest all the time according to during count h during electricity consumption; F is the correction factor (getting 1.05 usually) of battery discharging efficient; P0 is average load capacity kW; L is the maintenance rate (getting 0.8 usually) of battery; U is the depth of discharge (getting 0.5 usually) of battery; Ka is the proportion of goods damageds (getting 0.7-0.8 usually) that comprise ac circuits such as inverter.
In sum, as long as,, just can choose suitable group with reference to battery and the solar module performance parameter that manufacturer provides according to the accumulator capacity of calculating and electric current, voltage and the power of solar cell array
Part model and specification.Can determine to constitute the serial number and the number in parallel of the assembly of square formation thus.
On described battery 2 and the circuit that air compressor 4 is connected, be provided with inverter 3, provide alternating current to air compressor 4 by inverter 3.
The effect of batteries is to store the electric energy that is sent when solar cell array is subjected to illumination, batteries just can power to the load at any time under night or rainy day situation, the DC voltage of batteries in most cases is the alternating current that will direct current be transformed into 220V by inverter 3, this is because solar panel 1 and battery 2 send all is direct current, when load was AC load, inverter 3 was indispensable.So inverter 3 wants can guarantee to export an alternating current that voltage is stable, no matter be that fluctuation appears in input voltage, or load changes, it all will reach the certain voltage and the lasting accuracy of frequency, could guarantee the convenient usefulness of mountain village peasant household water system like this.Certainly, also unnecessary electric energy can be fed back to electrical network by controller 10, or withdraw from from electrical network.
The structure of the diode that counnter attack is filled:
On solar panel 1 and the circuit that battery 2 is connected, be provided with the diode that counnter attack is filled, being set to of its polarity: when solar panel 1 does not generate electricity or short trouble occurs, its circuit is oppositely ended.
In the system component of solar photocell power supply constitutes, be provided with counnter attack fill the effect of diode be avoid since solar cell array overcast and rainy and when not generating electricity night or when short trouble occurring, batteries is discharged by solar cell array.It is connected in the solar cell array circuit, plays unidirectional conducting effect.Require it can bear enough big electric current and forward drop little, reverse saturation current is wanted little commutation diode.
The mountain village water supply installation cost analysis of solar energy " pressure accumulation ":
Mountain village, peasant household's water supply installation and the water-supply systems of solar energy " pressure accumulation " are carried out the cost contrast, because the technical characterictic difference demonstrates the difference of manufacturing cost, need the place of supplying water separately with regard to mountainous rural area, orchard, hillside, rural area field irrigation etc., have very considerable social value and important economic value with the mountain village peasant household water supply installation of solar energy " pressure accumulation ".Describe below by two forms:
