Below in conjunction with accompanying drawing embodiments of the invention are done detailed description.
With reference to figure 1, be the structural representation of closet system according to an embodiment of the invention.In this embodiment, closet system comprises two lavatories: lavatory 10 and lavatory 10 ', both have same or analogous structure, therefore are described in conjunction with lavatory 10 at this.Be understandable that closet system can comprise a plurality of lavatories, using for more people simultaneously, and can increase the dirt treating capacity.
Closet system comprises lavatory 10, vacuum tank 20, heater 30 and vacuum extractor 40, be provided with dirt collection bin 13 in the vacuum tank 20, lavatory 10 is connected with dirt collection bin 13, and vacuum tank 20 is connected with vacuum extractor 40, and heater 30 is connected with vacuum tank 20.During use, dirt enters into the dirt collection bin 13 that is arranged in vacuum tank 20 by lavatory 10, and is heated by 30 pairs of dirts wherein of heater.Because have vacuum in the vacuum tank 20, so the boiling point of sewage is lower in the dirt, by heater 30, moisture wherein can be by rapid evaporation.
Above-mentioned lavatory 10 can comprise vacuum bed closet 11, and vacuum water closet 11 is connected with above-mentioned dirt collection bin 13.On vacuum tank 20, can also be provided with removable cover 21, in order to the sealing that keeps vacuum tank 20 when the trapped dirt not.The folding of removable cover 21 can be controlled in several ways, such as by hotness control, pressure control etc.Preferably, on dirt collection bin 13, can also be provided with handle 131, thereunder can also be provided with slideway 132, move to make things convenient for it.
Heater 30 can comprise solar panel 31, solar water heater 32, water back 33, water pump 34 and motor 35.Solar panel 31 is arranged on the top of closet system, and its solar energy that is connected with solar water heater 32 absorbing offers solar water heater 32.Be connected with water back 33 on the solar water heater 32, water is heated the back and heats by 33 pairs of vacuum tanks 20 of water back.The circulation of hot water relies on the water pump 34 that is arranged on the water back 33 to realize that water pump 34 is connected with motor 35 thinks that it provides power.Be understandable that above-mentioned heater 30 has only been described an embodiment, it can be realized by a plurality of modes.For example can realize by below vacuum tank 20, heater being set simply.
Vacuum extractor 40 comprises vacuum pump 41 and flap valve 42.Vacuum pump 41 can be connected with above-mentioned motor 35 thinks that it provides power.Vacuum pump 41 is connected so that it is vacuumized with vacuum tank 20 by vacuum pipe.Flap valve 42 is arranged on the vacuum pipe, with the vacuum in the further assurance vacuum tank 20.
Closet system may further include water tank 50 and ventilation fan 60.Water tank 50 and vacuum bed closet 11 are in order to wash it.Ventilation fan 60 is installed on the lavatory takes a breath.
With reference to figure 2, be the structural representation of the vacuum pump of closet system according to an embodiment of the invention.Vacuum pump (water jet pump) 41 comprises nozzle 411, suction chamber 412, mixing chamber 413 and diffusion chamber 414, and they connect successively.Its operating principle roughly can illustrate by four processes:
1) course of injection---the working flow with certain pressure (getting final product about 0.4MPa) is when convergent nozzle, and speed is by V PBe raised to V P1, pressure is by P PDrop to P S, promptly outside jet hole, form vacuum.According to fluid mechanics principle, the flow velocity of nozzle exit is expressed from the next:
V P 1 = Φ 1 · 2 g · ΔP P / ρg m / s - - - 1
In the formula 1:
Figure BSA00000486528500042
---the efflux coefficient of nozzle is taken as 0.975-0.950 usually;
Δ P P=P P-P SBe called the work pressure drop, Pa;
The density of ρ---working fluid;
G---acceleration of gravity, g=9.81m/s 2
Working fluid can be determined by following formula by the instantaneous delivery of nozzle:
Q P=V P11/4 towering d 1 2m 3/ s 2
In the formula 2: d 1---the diameter of jet expansion
By formula 1 and formula 2 as seen, the muzzle velocity of nozzle, rate of discharge are subjected to Δ P PInfluence very big, after the jet pump structure size was decided, the flow through speed and the flow of nozzle of working fluid just depended on Δ P PSize.Δ P PBig more then V P1And Q PJust big more; Otherwise it is then more little.
2) the injection process---working fluid forms vacuum at suction chamber, and the fluid that is sucked is introduced into suction chamber under the effect of pressure reduction, enters mixing chamber with the working fluid fusion, and the flow that liquid enters mixing chamber section 2-2 is: Q=Q P+ Q Sm 3/ s 3
In the formula: Q P---the flow of working fluid, m 3/ s;
The flow of Qs---driving fluid, m 3/ s.
The flow of driving fluid is called flow-rate ratio or is called volume mass ratio of induced-to-inducing air U with the ratio of the flow of working fluid 0:
U 0＝Qs/Q P 4
The uniformity coefficient of two kinds of fluid mixing is very big to the performance impact of water jet pump in the injection process.Distance L c between jet area and the mixing-chamber inlet cross section is called larynx mouth distance, and it is more important structural parameters of water jet pump.When the Lc value is excessive, the flow of driving fluid is increased, energy loss increases, even it can not be pressurized to enough discharge pressures, and the refluence phenomenon will occur in the periphery of mixing chamber.The Lc value is too small, and the flow of driving fluid is reduced, and energy loss is increased.The definite theoretical calculating and mensuration repeatedly of experiment of normally depending on of Lc value, the sectional area (f of its value and mixing chamber inlet 2) and the long-pending (f in jet area 1) ratio (being that larynx mouth area is than m) relevant, that is: m=f 2/ f 1, choosing of Lc value sees Table 1.
The optimum larynx mouth of table 1 is shown apart from the Lc value
Larynx mouth area compares m Optimum larynx mouth is apart from Lc
1.5-3.0 (0.5-1.5)d 1
4.0-6.0 (1.0-2.5)d 1
7.0-25.0 (1.0-7.0)d 1
Annotate: d in the table 1 1---the diameter of jet expansion
3) mixed process---mixed process is that 23 sections in Fig. 2 carry out.This section is called mixing chamber.The length L of mixing chamber KSize, energy exchange between convection cell, speed tangible influence evenly arranged.L KBe worth too smallly, the momentum-exchange between fluid is not thorough with making, and exit velocity is inhomogeneous, and then increases the flow losses of diffusion chamber, causes pump performance to reduce; L KBe worth excessively, then friction loss increases.L KThe size of value directly has influence on the homogenising degree of two kinds of fluid velocities and energy loss size therebetween, so, L KGenerally get (6-7) d 3, d 3Be the mixing chamber outlet diameter.
4) diffusion process---diffusion process is that the 3-4 section in Fig. 2 is carried out.This section is the conical pipe of a section or several sections expansions, and working fluid and draw and thank to fluid through after the mixing of mixing chamber just enters this diffuser, and the purpose of diffusion process just makes the kinetic energy of fluid be converted to the pressure energy.Can successfully discharge the pump housing through the fluid behind the diffusion, the energy loss of this process is less.
Porta Potti treatment technology of the present invention utilization be the environment thermal source.The major parameter of thermal source has temperature and heat.What of required heat the Porta Potti oven dry handle, and depends primarily on the total amount of sewage; To the requirement of heat source temperature, then depend on the vacuum in the device.Vacuum is high more, and the boiling point of sewage is just low more, and is just big more with the temperature difference of thermal source, just can make full use of the heat in the environment thermal source more.Enough vacuum is the most basic prerequisite of Porta Potti, also is the prerequisite of vacuum collecting sewage.If the enough height of vacuum are boiling point when being lower than environment temperature, thermal source (as overcast and rainy, when the solar water actuator temperature is low) is not provided this moment, promptly sewage can evaporate oven dry voluntarily under condition of high vacuum degree at normal temperatures.When moreover Porta Potti is handled and do not require and reach boiling, as long as evaporation just can.
According to the advantage of closet system of the present invention mainly contain following some:
1) avoids using chemical agent in the dirt processing procedure.Above-mentioned processing procedure is the evaporation process of a physics, and what need only is vacuum and temperature, does not need to add any chemical agent.This can be avoided secondary pollution.Dirt after the processing can be directly used in fertilizer of crops.
2) running cost is low, and energy consumption is few.The whole of above-mentioned closet system use are environment heat, and consume heat energy also seldom.Be fit to the requirement of " low energy consumption, high environmental protection ".
3) dirt reaches the highest standard of zero-emission, and operation and operational management are very easy.
4) equipment is simple, and cost of investment is few.It needs vacuum plant and heater, and keeping by water jet pump of vacuum finished, and cost is very low; The later maintenance workload of heater also seldom.
5) the water-fast power impact property of this system is very good.
6) less demanding to lavatory flushing liquid.Handle product and can be used as organic fertilizer, lavatory flushing liquid directly uses fresh water to get final product.Owing to adopt vacuum collecting,, and can be recycled so the flushing water consumption seldom.Be to reduce secondary pollution, can be less with or without detergent for toilet.
7) collection and treating capacity are big, satisfy instructions for use easily.Above-mentioned closet system uses vacuum collecting, vacuum drying to handle, and the sewage volume dwindles greatly.If again to its compression, collecting amount will double again.
8) dirt is to pass on after totally-enclosed processing and the drying again.In the whole operation process, can not produce contact beastly.
The present invention is illustrated by the foregoing description, but should be understood that, the foregoing description just is used for for example and illustrative purposes, but not is intended to the present invention is limited in the described scope of embodiments.It will be appreciated by persons skilled in the art that in addition the present invention is not limited to the foregoing description, can also make more kinds of variants and modifications according to instruction of the present invention, these variants and modifications all drop in the present invention's scope required for protection.Protection scope of the present invention is defined by the appended claims and equivalent scope thereof.
