Description
Technical field
The invention belongs to the green building field of energy-saving technology, more specifically, relate to water potential energy recovery and water body reuse integrated system in a kind of highrise building.
Background technology
Turbine generator is to use a kind of very widely TRT at present; It is used through drawing kinetic energy to fluid and converting thereof into electric energy; The turbine generator that for example utilizes waterpower to generate electricity can draw kinetic energy, the morning and evening tides that the waves beat upon the seashore rise move back in kinetic energy and the current of the seawater potential energy that produces that flows from eminence toward lower generate electricity; For example utilize the turbine generator of firepower or solar electrical energy generation to make fluid produce kinetic energy and then generating because of the temperature difference flows again through heating.
Highrise building is because its space availability ratio is high; The population density is big; Often have the characteristics that water supply volume is big, displacement is big, and these sewage of discharging has very high potential energy mostly, in the present great majority building; People directly are discharged into public sewer 7 with these sewage through pipeline, and the potential energy in the middle of this makes is slatterned in vain.
In the prior art, turbine generator can be through drawing kinetic energy and converting thereof into electric energy utilization to fluid; In above-mentioned highrise building; If be installed on building sewage conduct bottom to turbine generator; Turbine then also can transfer the kinetic energy that sewage is produced to electric energy when eminence falls, the electric energy that utilizes this method to produce can be tried to achieve by following formula.
P＝ηrhg； (1)
Wherein η is a conversion efficiency, and r is flow (kg/s), and h is water source height (m), and g is acceleration of gravity (9.8m/s
2), P is for producing the power (W) of electric energy.
According to the guide (National Bureau of Standards) of NBS, the size of a drainage pipe should be tried to achieve according to following formula.
q＝27.8r
5/3d
8/3； (2)
Wherein: q is pipe capacity (gpm); Account for when to be current in the pipe mobile ratio of pipeline area of r is usually between 1/4～1/3; D is pipe diameter (inch).
Domestic block with one 70 floor height is an example; Suppose that every layer of mansion has 20 families, each household has 5 people, and the water supply volume of everyone every day is 168 liters; If put together all sewage; The sewage of this mansion discharging every day is 1176000 liters, and with reference to formula (2), this mansion needs one 4 inches pipeline to come sewage effluent.
Calculate the electric energy that these sewage can produce below, in order to obtain The above results, the kinetic energy when calculating sewage arrival turbine generator earlier; Referring to Fig. 1, be illustrated as sewage and be attached to the flow regime sketch map that flows downward on pipeline 10 walls, wherein to account for pipeline 10 area maximum values be 1/4 to 1/3 to sewage 20; The center of pipeline 10 is an air 30, and behind sewage 20 flow ipes 10, sewage 20 can quicken downwards because of gravity; But sewage 20 flowing velocities are fast more, and tube wall is also just big more to the frictional force that sewage 20 applies, after the numerical value of frictional force is equal to gravity; Sewage 20 just can stop to quicken and flowing downward with fixed speed; This speed is called as terminal velocity (Terminal Velocity), and sewage 20 by static to accelerating to the distance that reaches terminal velocity, be called as ultimate distance (Terminal Length); According to the drainage flow state of NBS's deduction and the formula of flowing velocity thereof, the design formulas of above-mentioned terminal velocity and ultimate distance is following:
L
T＝0.052V
T 2； (4)
V wherein
TBe terminal velocity (fps), L
TBe ultimate distance (ft) that q is discharge (gpm), d is pipe diameter (inch).
With 70 layers of mansion in the last example with have the identical population density and per capita 30 layers of mansion of water supply volume compare; The sewage volume of two mansions generation every day is respectively 1176000 liters and 504000 liters; Suppose that current are the steady motion of a fluid (Steady Flow); According to formula (3) and (4), the effluent stream of two mansions is when separately gutter, and its terminal velocity is respectively 5.46m/s and 3.88m/s.
Because after the sewage current arrive terminal velocity; Sewage can be converted into friction loss to the dirty gravitional force that discharges; So the kinetic energy when it arrives the building bottom is very limited; According to formula (1), if in the building bottom turbine generator is installed and supposes that conversion usefulness is 80%, then the power of turbine generator is merely 162W and 35W.
And consider do not have friction loss, the release of central potential energy can be converted into kinetic energy in the ideal case, and central kinetic energy also can be converted into electric power through turbine.
Average output power because of turbine generator: P=ρ ghQ; (5)
Wherein: ρ is the density of water, and g is an acceleration of gravity, and Q is a flow, and h is about half height of building.
In the ideal case; Turbine generator is respectively 18kW and 2.85kW at the average output power of 70 layers of mansion and 30 layers of mansion; Be to be about 0.9% and 1.2% with the energy that can draw, visible, sewage is very huge along the flow downward friction loss that caused of tube wall; The energy of practicing thrift is compared with investment, does not calculate very much.
On the other hand, the contradiction between the water demand that current water resource generally lacks and people increase increases the weight of day by day, People more and more how the general used water reclaim and be used; This process is commonly referred to middle water reuse; The water Treatment for Reuse has three big common technologies haply in this now, is respectively coagulation and filtration, biological treatment and deposition and the film technology of grading; Wherein the above two shortcomings are that floor space is big and handle length consuming time; And the latter possesses occupation of land less and advantage such as process is quick and easy, can be arranged at the mansion bottom, is particularly useful for the metropolis of an inch of land is an inch of gold.
The membrane separation process of reality generally is by compressor hyperbaric environment to be provided; And push sewage to filter membrane and realize, select the milipore filter (about 2-50 nanometer) can be in daily life at a distance from walking suspended particles, bacterium and virus with water reuse requirement in reaching, more specifically; The membrane separation process of present stage can be divided into micro-filtration membrane (about 50-5000 nanometer), milipore filter (about 2-50 nanometer), nanofiltration membrane (less than 2 nanometers) and reverse osmosis filter membrane; Pollutant that each filter membrane can intercept and desired pressure and inequality, for example micro-filtration membrane can be at a distance from walking bacterium and suspended material, but can not be at a distance from walking virus; And milipore filter can not only be at a distance from walking bacterium and suspended material; Can also be at a distance from walking virus, nanofiltration membrane and reverse osmosis filter membrane then decapacitation separate outside the above all contaminants, also can isolate multivalent ion and monovalention separately.Generally speaking; Compared with becoming originally from the required pressure of various worry films; The implementation cost of micro-filtration membrane and milipore filter is lower, and the water yield of its recovery is also more, shows the different filter membranes of a pair of employing and carries out the need of film when separating and compare with pressure, energy loss and cost.
| Filter membrane | Pressure (bar) | Power consumption (W/m 3) | Cost (Yuan/m 3) |
| Micro-filtration membrane/milipore filter | ?0.5-2 | 0.1-0.2 | 0.5-0.9 |
| Nanofiltration membrane | ?5-10 | 0.3-0.5 | 1.4-2.3 |
| The reverse osmosis filter membrane | ?10-20 | 0.5-1.0 | 2.3-4.7 |
