Definitions
- the invention relates to a purification process for contaminated with accompanying water and the associated cleaning equipment.
- the aforementioned methods are usually designed so that the liquid to be purified is heated by energy supply above its boiling point, after boiling a forced cooling takes place and thus a high throughput in the plants is achieved. Ultimately, however, the high throughput is purchased at a high level of investment and energy.
- Another disadvantage is that the temperature within the insulating housing is not controllable. Control options for the temperature level in the insulating housing exist at most on the order of magnitude of the temperature increase and on the amount of polluted water pumped through the system. A direct influence on the temperature of the air inside the housing is not given.
- the boiling, evaporation or condensation assemblies are placed in a mandatory housing or encapsulation. Energy exchange and phase change of the contaminated water can be achieved by way of free convection in a mostly existing air flow without additional drive energy. Corresponding suggestions are contained in DE 24 59 935 A1, DE 30 10 208 A1 and DE 199 29 212 A1.
- a cleaning system for contaminated water should be designed as a compact system with a humidifier operating in the cross-flow principle.
- the humidifier is a rotating convection drum.
- the system is to be supplied with solar heated contaminated water and supplied via a photovoltaic system and associated accumulators with electrical energy.
- a stationary cleaning system can be operated with a cleaning method in which the heating of the loaded water and the process air takes place via solar energy.
- evaporators there are a number of proposals for their implementation.
- DE 30 10 208 A1 proposes providing a fleece for the evaporator which can be heated by a heat exchanger associated with the fleece.
- the liquid to be evaporated should be able to flow down over woven or nonwoven webs. In the absence of suitable ancillary equipment, this can only be a disordered, waterfall-like flow. In addition, it is indispensable to set up the system with exactly the right balance every time you use it.
- the supplied contaminated water has a temperature of up to 30 ° C when the cleaning systems are operated in areas of intense sunlight. If the supplied contaminated water expediently used for cooling the condensation region, this results in a limitation of the condensation performance.
- the known large-scale seawater desalination plants are stationary. The amount of purified water is thus only available at the location of such facilities and it must be brought to users with additional resources. As far as the design of compact systems with solar heating is proposed, these can not achieve the necessary benefits, which is why such systems must be sized accordingly and / or must be installed multiple times. According to Hendrik Müller-Holst, a compact system with an evaporator area of 76 m2 should be able to provide a cleaning capacity of 0.37 lm "2 h " 1 .
- Contaminated water - is a mixture of substances with a liquid phase and a vapor pressure below the prevailing ambient pressure, from which the water content can be obtained by evaporation and condensation already at temperatures below the boiling point. It is in particular a mixture of water and accompanying substances of different types.
- Reservoir - is any container containing contaminated water.
- Condensation area - is a device which contains technical means which have a lower temperature compared to the temperature of a gaseous medium and therefore cause a condensation process on the outside of the area or the associated technical means.
- Collecting device - is a device which receives condensate accumulating on the outside of the means forming the condensation region and leads it away from the condensation region via a line.
- Condensate tank - is any container in which condensate carried away from the condensing area is collected and kept ready for further use.
- Heating device - is a device that makes it possible to heat the liquid medium coming from the condensation zone and thus increase the vapor pressure of the medium.
- Water Distributor - is a device designed to distribute the heated contaminated water in the form of droplets to a humidifier.
- Humidifier - is a device in which liquid medium supplied from the heating device is superficially distributed and evaporates to a greater extent due to the increased vapor pressure of the liquid medium.
- a polluted water purifying method uses a plant consisting of at least one loaded water pumping device, a condensing section, a condensate tank, a heater and an evaporation section. Furthermore, the system includes a ventilation duct, which connects the evaporation area and the condensation area with each other and allows a moving air flow through a fan.
- the listed components are designed so that they can co-operate with a view to operation with a lower temperature difference than usual.
- Necessary energy supply as for example in the heating device, preferably takes place via renewable forms of energy or via energy surpluses of processes not belonging to the process.
- a closed housing is executed.
- the condensation area within this enclosure are at least the condensation area, the evaporation area with a water distributor, a fan, a partition wall between the condensation and evaporation area and collecting facilities for condensate and dripping contaminated water.
- the closed housing may be provided with a thermal insulation.
- the heating device within the closed housing.
- the initially listed and interconnected facilities are only flowed through by the polluted water.
- the said devices are flowed through or through the air flow. Only in the condensation region is a second, the purified, medium. All interacting media work under atmospheric pressure conditions, which is why special technical expenses can be omitted.
- the components described above can be designed so that they are adapted as a whole system the usual load dimensions for road or rail transport and thus are transportable as a whole system. Even smaller embodiments are also conceivable.
- the individual areas of the cleaning system described above are operated according to the cleaning method according to the invention so that the peak temperature of the contaminated water does not exceed 85 ° C if possible. This makes it possible to heat the polluted water in a solar heater solar.
- the cold contaminated water is first conveyed by means of a pumping device in the condensation region.
- the condensation zone is a heat exchanger which removes heat from a heated air flow and is cooled down by the liquid flow to the lower temperature of the supplied contaminated water, so that the entrained in the air to be cooled purified liquid particles can be condensed and collected at the surface of the condensation region.
- the condensate can be fed to a condensate tank, where it is available for other uses.
- the charged water is fed to a heating device, in which it is heated up to a temperature of about 85 ° C.
- the heated contaminated water is passed via a line to the evaporation device, where it is distributed dropwise over the surface of the evaporation device and falls down due to its own weight. Effective evaporation takes place in the evaporation zone, with the amount of evaporation dependent on the temperature of the contaminated water, the temperature of the surrounding air and the temperature of the evaporation zone, as well as on the velocity of the airflow.
- the falling drops of water hit an obstacle, which slows down the previously free fall.
- the obstacle is a grid-like structure whose dimensions are such that no falling drop has a free passage. Furthermore, that the impacting drops adhere to the lattice-like structure and thereby hang on the parts of the structure due to their adhesion and surface tension. At the same time, the holding force for the water droplet is greater than the weight of the same. If a certain droplet size is exceeded, the equilibrium is disturbed and the water droplet falls off the structural element.
- the motion of the drop of water is by design measures within the grid-like structure to an area smaller than 10 cms' 1 set, with a speed of 7, 5 cms "has proved advantageous.
- 1 in the evaporation zone is usually worked with an excess of water, so that the lower At the end of the evaporation zone, excess amounts of water can be drained off, collected and returned to the reservoir.
- the air flow is used according to the cleaning method according to the invention on the one hand to transport the evaporated liquid from the evaporation area to the condensation area.
- This refinement of the cleaning method makes it possible to use the respectively optimum means both in the evaporation region and in the condensation region and to adapt them to the process in such a way that they operate with maximum effectiveness.
- the temperature difference required for the process can also be influenced by the rate of flow of the air, that is to say by the amount of air per unit of time.
- the amount and temperature of the air stream can be regulated. Equally important is that the air flow is kept in circulation. In any case, this is not a disadvantage when the cleaning method is used to purify water, and only the amount of condensate per unit time is decisive for the effectiveness of the cleaning process. Since heating with other energy available, there are no disadvantages in terms of energy use.
- the cleaning system combines the components already mentioned in the description of the cleaning process, the supply, the pumping device, the condensation zone, the heating device and the evaporation device.
- the evaporation device / the humidifier and the condensation zone are components of the cleaning system, which are also arranged in a ventilation duct.
- a line connects the supply of contaminated water with the pumping device, which in turn conveys the polluted water via a line to the arranged in the ventilation duct condensation region.
- the heater and the water distributor also towards the heater and the water distributor.
- the condensation zone is essentially an air-water heat exchanger having a surface which condenses water contained at its relatively low temperature from the passing air stream.
- the condensation region or the heat exchanger is designed so that moisture condensing on its surface following moisture can easily drain off and detected by means of a collecting tray, flow via a line connection in a condensate tank and kept there for further use.
- the contaminated water has a temperature which largely corresponds to the temperature present in the reservoir.
- the airflow sweeping the condensation region has been heated in the evaporation device. When flowing through the condensation region of the heated air flow due to the temperature difference must necessarily release moisture. The resulting heat of condensation warms the contaminated water.
- the heater belonging to the system serves to heat the contaminated water after flowing through the condensation region to a higher temperature. It is sufficient if the excess temperature of the contaminated water to a value of at least 50 ° C, better to 85 ° C, but not above the boiling temperature of the water is heated.
- the evaporation device / humidifier is arranged coaxially in the ventilation duct. It is supplied from the heater with heated contaminated water.
- the evaporation device is a body with a large surface and an increased flow resistance, thus the highest possible turbulence the intake air and thus an intensive contact between air and water arise.
- the preferred form of evaporation device is a grid-like structure designed so that there is no free passage for falling water droplets. It is charged from above with freely falling water droplets, which initially impinge on the lattice-like structure, then hang in the structure drop or lentil-shaped until the resulting droplets dissolves due to its Eigengeweichtes and further falls down.
- the grid-like structure is designed so that a resulting flow rate of less than 10 cm / s is realized. Lower flow rates increase the residence time and thus at the same time the degree of evaporation relative to a single drop of water.
- Other embodiments for the evaporation device may operate on the principle of the wet cooling tower of the polluted water and forced ventilation.
- Further preferred embodiments can work with superficial distribution of the contaminated water on textile fabrics, wherein these in turn can preferably be folded to achieve a large surface, as a coarse mesh, as spacer fabric, as a net or as hanging threads or cords.
- the distribution of the heated loaded medium takes place at the outlet side of the evaporation device.
- the evaporation device is a body which, with continuous operation of the cleaning system, quickly assumes the temperature of the inflowing, contaminated water and thus ensures a high degree of evaporation.
- the plant described above can be modified depending on specific conditions of use. If the cleaning system according to the invention is used on a coast or in a standing or flowing water body, the water can form the reservoir. The cleaning system can then stand, for example, directly in the water or be supplied via a supply line.
- the pumping device may be designed for manual operation.
- the ventilation duct can be designed so that a buoyancy is created by the heating of the air in the evaporation device and thus the air flow starts automatically.
- the first section of the ventilation duct can preferably be arranged vertically.
- the heater can work with solar heating, so no external heat quantities and auxiliary energy are necessary for the heating of the contaminated water.
- the cleaning system can be made compact, so it is mobile and can be transported by vehicles.
- the ventilation duct With appropriate design of the ventilation duct this can take over the function of the condensate collection tray in the condensation region. If the cleaning system is connected to a mains network, the condensate tank can be omitted. With the cleaning system associated control device operation with high efficiency, that is condensation power, ensured. Depending on the respective requirements, important measured values are recorded within the cleaning system and processed by the control device.
- control device can work out the necessary control variables by comparison between actual values and setpoints, by querying permissible ranges of values and comparison with these or else using predetermined algorithms, and transmit them to the system components to be controlled.
- control device It is also possible in the control device to deposit a program that takes over the fully automatic control of the cleaning system.
- a manipulated variable for the heating power of the heater is generated, which can be minimized in terms of energy saving at the same time.
- the control device can take into account all these influencing variables in a suitable way.
- the cleaning system may optionally be used on heated process water. This is possible, for example, if in industrial plants, due to the processes to be carried out there, charged water with temperatures in the sub-boiling range is available. In this case, can be dispensed with the heater. The condensation zone is then not connected to the circuit of the loaded and to be cleaned water, but a pure cold water rinse cycle.
- the cleaning system 1 consists essentially of the main components listed below.
- a reservoir 2 from which contaminated water 3 can be supplied, a housing 4 which has a condensation area 5, a humidifier 6, a water distributor 7, a dividing wall 8, a flow channel 9 leading through humidifier 6 and condensation area 5, a receptacle 10 for Purified water 1 and a collecting container 28 for dripping residual water 22 are combined in one unit.
- a line 12, which supplies the contaminated water 3 to the condensation area 5, and a heating device 13 are furthermore necessary, the heating device 13 being connected via a line 14 to the condensation area 5 and via a line 15 to the water distributor 7.
- An essential component of the cleaning system 1 is furthermore in the flow channel 9, a fan 16, which circulates the air flow 17 at an optimum speed for the cleaning process.
- the cleaning method according to the invention consists in that the cleaning system 1 is fed via the line 12 loaded water 3 in the condensation region 5.
- the temperature of the loaded water 3 may have values above 30 ° C., as is the case, for example, in dry hot regions of the earth.
- an air flow 17 is circulated, which is heated by the heater 13 and the supplied via the line 15 to the water distributor 7 heated contaminated water 3 to an operating temperature near the boiling temperature of the loaded water 3. With the help of the fan 16, this air flow is kept in motion.
- the cleaning system 1 thus operates in the best case with a temperature difference between contaminated water 3 and the air flow 17 of up to 80 ° C, in less favorable cases with a temperature difference down to 5 ° C.
- the cleaning system. 1 Therefore, optimized for operation with a temperature difference of about 40 ° C, with larger temperature differences further increase performance.
- the contaminated water 3 flows via the line 12 into the lower region 18 of the condensation region 5. In this region of the condensation region 5, the lowest temperature is thus even present in the condensation region 5 and within the housing 4. As it flows through the lines of the condensation region 5, the supplied contaminated water 3 heats up, since it receives heat quantities from the air flow 17. At the upper end 19 of the condensation region 5, the contaminated water 3 thus already has an elevated temperature. Via the line 14, the loaded water 3 of the heater 13 is supplied and heated in this with originating from external energy sources heat tight up to a temperature near the boiling point.
- the heating device 13 is preferably supplied with heat quantities from process heat, which generally arise as waste heat during industrial processes.
- Such heat sources may be, for example, waste heat from elevated temperature industrial processes, heat loss from the operation of combustion and electric motors, compressors, cogeneration units, waste heat from electrical converters, electrical storage devices or geothermal. It is also possible to use the solar heating, if other energy sources are not permanently available and restrictions on the availability of the cleaning system 1 can be accepted.
- the heated in the heater 13 to a high temperature contaminated water 3 is supplied via the line 15 to the water manifold 7. Via openings 20, the water distributor 7 discharges the heated loaded water 3 in the form of drops, the drops 21 dropping downwards due to their weight and bouncing in the humidifier 6 on obstacles 26, by which they are first held.
- the obstacles 26 are designed so that they provide the drops 21 only a very small contact surface. That is, the contact area for the drops 21 is dimensioned so that the holding force is slightly above the weight of the drops 21. The forming drops thus hang on the underside of the obstacles 26, thereby have a relatively large surface and can evaporate over them.
- the circulating in the housing 4 air flow 17 takes in the humidifier 6, the evaporating amounts of water by flowing from below into the humidifier 6, flows through it, and exits at the upper end of the same, the air flow 17 at the outlet from the humidifier 6 a Moisture content near 100% and ideally at the same time has a temperature near the boiling point of the water.
- the air flow 17 therefore, during continuous operation of the cleaning system 1, an equilibrium of the shape arises that the temperature in the air flow 17 sets itself to a high value and the air humidity to a value close to 100%.
- the actually resulting values are first determined by the size of the heat losses occurring in the cleaning system 1.
- the housing 4 is provided with an insulation 27.
- the condensation area 5 is the area with the lowest temperature during operation of the cleaning system 1, since this constantly charged water 3 is supplied with a low input temperature. Due to the temperature differences in the region of the lines and the collecting tray 24 of the condensation zone 5 designed as a heat exchanger, condensing water droplets form on its surface. These move downwards until they are in the lower region 18 of the condensation region 5 due to their size and Draining self-mass, collected in a drip tray 24, discharged via a line 25 and 11 are supplied to the collecting container 10 as purified water.
- the cleaning method is therefore based on the fact that in the interior of the housing 4, an equilibrium state is formed, which is disturbed by the supplied with a low temperature charged water 3 and due to this disturbance of equilibrium in the condensation region 5, a falling air movement sets. This in turn leads in the humidifier 6 to an upward air flow.
- a further source of interference for the developing equilibrium is the water distributor 7, through which a supply of amounts of heat takes place via the discharged drops 21.
- the process which always strives for an equilibrium, is additionally disturbed by the fact that a forced circulation of the airflow 17 is forced by means of the fan 16.
- the operating parameters of the cleaning system 1 are detected with the aid of a control device 29 and control signals for the operation of the fan 16 are determined from the measured values obtained.
- the amount of purified water 11 produced per unit time can be detected and, according to previously empirically determined results, a control variable for the fan 16 can be generated by comparing between the various operating parameters and the amount of purified water 11 per unit of time.
- the invention thus takes into account that the result of the method according to the invention must be a maximization of the amount of purified water 11 to be obtained.
- the control device 29 can be designed such that it maintains an operating point which has been found to be optimal or an operating regime which has been found to be optimal. It can work in such a way that further external influences on the cleaning system 1 are included in the control. This may be the temperature of the loaded water 3, the available amounts of heat for the heater 13 or the heat losses of the exiting from the circuit residual water 22 which are fed via a discharge line 23 again to the reservoir 2.
- Known stationary cleaning systems with solar heating achieve cleaning performance of about 0.14 lm “3 h “ 1 , improved systems cleaning performance of about 0.4 lm “3 h “ 1
- the system of the invention achieved by their optimized components and the optimized operating parameters, a cleaning performance of up to 42 lm “3 h “ 1 , based on a system volume of 1 m 3 and a flow temperature of the loaded water 3 in the water distributor 7 of 80 ° C.
- An experimental version of the cleaning system 1 according to the invention has a volume of 0.75 m 3 and a weight of only 75 kg. It delivers 750 1 of purified water in 24 hours.
- Preferred uses are the operation in conjunction with the electric power generation serving internal combustion engines, the waste heat is used. Likewise, the use of heat sources that generate waste heat when carrying out technical processes, which would otherwise be lost as waste heat.
- the small footprint of the cleaning system 1 according to the invention also allows uses that were previously not possible with known systems. For example, the installation in the engine room of a ship with simultaneous use of the waste heat of the ship's engine, in buildings in the use of waste heat from air conditioning, cooking appliances, drying and washing facilities or industrial heat sources or their waste heat.
- the compact cleaning system 1 can be used for a self-sufficient water supply when a sufficiently large reservoir 2 is assigned and at least via the reservoir 2 is a way to lower the temperature of the loaded water 3 therein again.
- the cleaning systems 1 according to the invention can also be designed in a significantly larger version with at least the same parameters if the required heat quantities are available at the installation site.
- Such a combination of cleaning systems with large-scale processes in petroleum processing, in power generation, in the production of cold and similar processes is possible.
- the cleaning system 1 according to the invention is designed such that it is suitable for carrying out the cleaning method according to the invention. It consists accordingly of the above-mentioned main components humidifier 6, condensation zone 5, a heater 13 and the water distributor 7. Furthermore, the cleaning system 1 a collecting container 10 for the resulting purified water 11 belong.
- the flow channel 9 is a closed channel. That is, the present in the flow channel 9 air flow 17 is in a circuit.
- the flow channel 9 is predominantly vertically aligned in a first section and receives the humidifier 6. That is, he encloses this.
- the humidifier 6 can be designed in various ways. In any case, it acts in such a way that the polluted water 3 comes into contact with the air flow 17, so that an evaporation process begins with the polluted water 3.
- the humidifier 6 may be a single component, which has formed a particularly large surface.
- the humidifier 6 may be a folded, rolled-up or shrunk textile fabric. It can also be a similar structure of felt, a fiber structure or nonwoven fabric. Further possibilities are the use of knitted fabrics, especially knitted fabrics, latticed or reticulated fabrics.
- the humidifier 6 may be a three-dimensional lattice-like structure made of plastic, metal or vitreous materials or of a metallic structure. It may be a heap of metal chips in a preferred embodiment.
- Other possibilities are the use of fleece, felt, cellulose glass or plastic fibers, so-called packing of ceramic, plastics or metals or in a floor arrangement in which repeatedly stacked collecting trays regularly overflow and thus allow a constant dripping of the contaminated water 3.
- the preferred embodiment of the humidifier 6 is a lattice structure with grid elements having such a small diameter that impinging water immediately forms drops to be suspended.
- the holding force of the grid elements is only slightly above the weight of the forming drops. With increasing droplet size these dissolve, fall and collide with other grid elements, so that the process is repeated.
- the velocity of the water droplets, which is reached when passing through the lattice structure, lies at a maximum of 0.1 ms -1, with an optimally designed lattice structure even lower.
- a simple embodiment of the humidifier 6 envisages completely dispense with additional internals and instead provide a water distributor 7, which rains the contaminated water 3, wherein the resulting drops 21, as in the embodiments described above, fall down due to their weight ,
- the contaminated water 3 is heated in a heating device 13 to a high temperature, but which remains below the boiling point of the loaded water 3. It is not relevant to the invention, in which way the amount of heat necessary for heating the charged water 3 generated and how they are introduced into the contaminated water 3.
- the air flow 17 is charged with moisture.
- the air flow 17 is heated, so that in the flow channel 9 an upward air flow is formed.
- a second section of the flow channel 9 is again oriented vertically.
- the condensation region 5 is arranged, which is preferably designed as a heat exchanger. It is irrelevant to the essence of the invention, which embodiment of a heat exchanger is selected.
- an insulating partition 8 is arranged between the humidifier 6 and the condensation region 5.
- the condensation region 5 is flushed through the line 12 with cold contaminated water 3, so that the condensation region 5 at its lower portion 18 has a surface temperature which corresponds approximately to the temperature of the loaded water supplied 3.
- condensation region 5 can be improved in various ways.
- a fin heat exchanger can be used, the fins are aligned vertically.
- a fin spacing can be selected, which precludes bridging by water droplets between two adjacent lamellae.
- lamellae with a surface coating which increases the flow rate of adherent water is particularly preferred.
- This can be a plastic coating.
- the cleaning system 1 described above can be configured further in various ways.
- a preferred embodiment of the cleaning system 1 provides for this a separate reservoir 2, in which the contaminated water 3 is filled.
- the reservoir 2 may be disposed below the humidifier 6 and so dripping charged water 3 can be recovered.
- the reservoir 2 or an additional container can be arranged in the earth region in order to keep the temperature of the loaded water 3 low.
- the heater 13 may be configured to heat the charged water 3 with solar energy. It may also be heated with amounts of heat from the combustion of fossil fuels or with electrical energy or with energy lost from non-cleaning plant processes.
- the heating device 13 can be designed as a solar collector or assigned to it.
- a particularly preferred embodiment of the cleaning system 1 envisages using a high-performance solar collector as the heating device 13 and downstream of this a plurality of humidifiers 6, which in turn operates with a plurality of condensation regions 5 and thus makes it possible to cascade several similar cleaning systems.
- an embodiment of the cleaning system 1 can provide that a humidifier 6 is followed by a plurality of condensation zones 5.
- the humidifier 6 can be designed in various ways.
- the humidifier 6 can be carried out without evaporator body by raining over a line 15 downstream water distributor 7, the contaminated water 3.
- the air flow 17 is in countercurrent to the droplet flow, which falls due to the weight of the individual droplets down.
- a preferred embodiment of the cleaning installation 1 furthermore arises when, in conjunction with an oversized heating device 13, which may be designed as a solar collector, an additional store for heated, loaded water 3 is assigned. An oversupply of heated polluted water 3 can then be cached and is, for example, after Sunset for the continuation of the operation of the cleaning system 1 again available.
- a further preferred embodiment of the cleaning system 1 can dispense with the arrangement of a heating device 13.
- the cleaning system 1 is supplied directly with process water from plants not belonging to the invention or processes as contaminated water 3. This makes it possible to harness otherwise lost amounts of energy in addition to the production of purified water.
- the cleaning system 1 can be designed with exclusively solar heating so that it requires no external energy except for the operation of a pumping device 30 and the fan 16 and optionally to be supplied measuring and evaluation.
- this can be designed to be mobile, as a vehicle body or in compact design for small consumers.
- the invention has the advantage that it makes it possible, with the involvement of waste heat of technical processes or natural, renewable energy sources run under normal pressure cleaning process for contaminated water and a suitable for carrying out cleaning system, compared with previously known cleaning systems and their methods at of the same size provides a much larger amount of purified water 11.
