Definitions
- the invention relates to a process for recycling of a waste water according to claim 1 and a Wasseraufberei ⁇ processing apparatus according to claim 6.
- Aseptic packaging is a prerequisite in particular in the food ⁇ technology to ensure the durability ver ⁇ derricer food even without cooling.
- the wet disinfection of plastic packaging such as PET bottles with diluted peracetic acid has developed in the food industry, especially in the Getränkeindust ⁇ rie to one of the standard processes used for this purpose.
- the disinfection is carried out with aqueous Peressigklad- solution containing a mixture of typically 2000 mg per liter of peracetic acid and hydrogen peroxide in the water.
- the object of the invention is to reduce the water consumption in industrial cleaning processes, especially in the wet disinfection of food packaging, the potential of energy savings should be given.
- the solution of the problem consists in a method for reprocessing a wastewater according to claim 1 as in a water treatment device according to claim 8.
- the process according to the invention for reprocessing a wastewater from an industrial process comprising an acid comprises the following steps:
- a base (caustic) is added to the wastewater, which originates, for example, from a rinsing process during the production of the packaging, so that the wastewater containing wastewater re (usually peracetic acid and / or acetic acid) is at least partially neutralized. Then the neutrali ⁇ catalyzed wastewater is discharged into a heat exchange process.
- a heat exchange medium which is so taltet ors- that the wastewater to be treated is heated to a ⁇ Ver dunstungstemperatur which is between 60 ° C and the boiling point of the wastewater.
- the heat exchange medium can be both a liquid and a gaseous medium.
- the temperature of the heat exchange medium may be in the range in which the wastewater is to be heated, but it may also have a significantly higher temperature, especially with gaseous media.
- the amount of heat in the heat exchange process of the heat exchange medium ⁇ order is transferred to the waste water depends very much on the mass flows and also on the physical state of the heat exchange medium ⁇ .
- the method according to the invention has various advantages.
- the first advantage is that with the pre-chosen process ⁇ up to 80% of the process water used so the flushing water of the packaging, which is obtained as waste water, can be recovered again, and the process may be added again.
- the process according to the method of the invention is significantly less energy consuming than the cost of fresh water to process water.
- the described method is energetically positive.
- waste heat from industrial processes that are below 100 ° C. can also be used.
- processes with a waste heat in this temperature range, from 60 ° C to 100 ° C are not recovered, but are released into the environment. It is thus an energetically favorable and ecological method .
- fresh water is prepared for an industrial process, wherein the fresh water is subjected to a high-temperature treatment of over 100 ° C, in particular of over 140 ° C.
- a high-temperature disinfection finally eliminates any germs that may still be present in the fresh water.
- the fresh water can be conducted in advance through a condenser of the condensation device, wherein the heat of condensation at the condenser is transmitted to the Frischwas ⁇ water.
- a further heat exchanger may be provided which removes the heat from the heated fresh water again.
- This heat removed from the fresh water can in turn be used profitably to heat the waste water to an evaporation temperature or approximately evaporation temperature (evaporation temperature means a temperature promoting the evaporation between 60 ° C. and the boiling point). Furthermore, it may also be expedient to apply the heat energy withdrawn from the heated fresh water again for heating new fresh water for high temperature disinfection.
- Another component of the invention is a Wasseraufbe ⁇ reitungsvoriques for reprocessing a, an acid-containing effluent.
- This device comprises a neuter ⁇ neutralization device for neutralization of the waste water by a base, and a waste water collecting device, and is characterized in that a heat exchanger is provided for heating the waste water to an evaporation temperature which is between 60 ° C and the boiling point of the wastewater.
- the boiling point of the wastewater is usually between 95 and 110 ° C, depending on the pressure conditions and the substances dissolved in the wastewater (especially salts after neutralization).
- the device comprises an evaporation device, wherein the evaporation device is used for partial evaporation of the heated wastewater. After evaporation, condensation of the evaporated waste water into a condenser takes place.
- FIG. 1 shows a schematic process representation for the water flow of rinsing water for rinsing packagings in the food industry according to the prior art
- FIG 3 is a more detailed representation of the Spülwasserrüc winnungsstrom according to Figure 2.
- the current state of the art for the treatment and disposal of rinse water as it is used for example in the food industry will be explained.
- fresh water 20 is added to a reverse osmosis system 18, the fresh water 20 'thus treated being subjected to a further high-temperature thermal treatment to achieve absolute sterility, which takes place in a high-temperature disinfection system 24.
- the fresh water 20''rendered germ-free by these processes now becomes one industrial process added. For example, Kings ⁇ NEN this PET bottles, are rinsed, for example, for the beverage industry.
- This process which may have any number of embodiments, is referred to schematically as water utilization device 26 in FIG. 1 and in the following figures. Remaining with the example that PET bottles must be rinsed for the beverage industry, a wastewater 2, which is obtained after the rinsing process, be contaminated with peracetic acid or with acetic acid and H2O2. This is because that the peracetic acid for the disinfection of PET bottles in the beverage industry and in the Lebensmit ⁇ Telindus trie is generally used.
- the wastewater 2 which now contains the organic acid peracetic acid or acetic acid, is collected in a Abwasserauffang- device, this wastewater collecting device is shown here schematically by a funnel. It may also be just a conduit, it does not necessarily have a corresponding catch ⁇ basin be present.
- the wastewater 2 contaminated with an organic acid is pumped into a neutralization device 27, from a base tank a base or a liquor is added to the neutralization device 27 in such a way that the wastewater 2 therein is as neutral as possible. Contains value.
- the existing acetic acid or peracetic acid is thus neutralized with a suitable alkali or base.
- the so catalyzed neutrali ⁇ waste water 2 is used as the residual water 32 in the sewer directed.
- the residual water 32 'of the prior art is not recycled.
- FIG. 2 In contrast to the prior art according to FIG. 1, in FIG. 2 the wastewater 2 is collected in the waste water collecting device 8 and a wastewater treatment device 28 is added.
- the wastewater treatment device 28 is shown very simplified in Figure 2, it includes, among other ei ⁇ ne evaporation device 12 and a capacitor device 14th
- the waste water 2 is preheated by a heat exchanger 10 to an evaporation temperature, which causes evaporation of the wastewater 2.
- evaporation is hereby ver ⁇ stood that water passes from the liquid phase into the gas phase, wherein the temperature below the boiling point lies.
- This has the advantage that 2 waste heat can be used from another industrial process 46 for the heat exchange process for heating up the waste water which would otherwise be discharged due ih ⁇ rer relatively low temperature free environment to surroundings.
- the temperature may also be typically at 400 ° C (exhaust heat from a gas turbine ⁇ ). It is possible that the gaseous waste heat medium is fed directly as a heat exchange medium 4 to the heat exchanger 10 or whether a further, not shown heat exchange process is interposed. Gaseous heat exchange media have a lower heat transfer coefficient than liquid heat exchange media. To achieve the desired evaporation temperature of the waste water 2, the heat transfer coefficients must be taken into account accordingly and in accordance with the available temperature tur from the waste heat of the process 46, the required mass flows ⁇ be calculated.
- the water treatment device described by tung 28 purified water 44 is sterilized itself and also preferably has no residues of acids, but for the Ver ⁇ application in the food industry an additional high temperature disinfecting 24 may be required, and therefore the purified water 44 such disinfecting device 24 one more time is added before it is available again for the rinsing process.
- FIG. 3 the water treatment device 1 schematically described in Figure 2 is shown in more detail.
- a fresh water 20 of a reverse osmosis unit 18 is added to the thus Prepared ⁇ preparing fresh water 20 'is onsvortechnisch in a Hochtemperaturdesin Stammi- 24 to about 140 ° C to 150 ° C heated the absolute sterility of the thus treated To ensure fresh water 20 '', which is used in a water utilization device 26 as a rinse water. Following the arrow marked with the reference numeral 20 ', which emerges from the reverse osmosis system 18, the fresh water 20' before it is passed into the Hochtemperaturdesin Stammionsvortechnischmaschinerus 24, first in a condenser 15 'passed, the part of the Abwasseraufleungsvor- device 28 is.
- the fresh water 20' is preheated, as in the condensation process, which will be discussed below, condensation heat is released by the condensation, the condenser 15 'acts as a heat ⁇ exchanger and the fresh water 20' with the condenses - Warms sations Creek.
- the energy demand, which is required in the high temperature disinfection device 24, and is added in particular in the form of vapor, for example, by a Dampfge ⁇ erator is, in this case already reduced because the waste heat from the condensation process can profitably be used for the high-temperature disinfection 24.
- the high-temperature disinfection 24 also takes place only for a very short time, which is sufficient to kill all germs from the fresh water 20 '.
- the thus treated fresh water 20 '' which in turn has a relatively high temperature, is then passed through another heat exchanger 11, in which it is cooled again to a usable temperature for the rinsing process.
- the heat exchanger 11 and the heat exchanger 23 in the high temperature disinfection system 24 ste ⁇ hen thus in constant exchange so that is lost in this process very little heat energy.
- the the fresh water 20 '' extracted in the heat exchanger 11 ⁇ heat is another point of the process still in use, will be which will be made.
- heat removed from the fresh water 20 "after the high-temperature disinfection for preheating the fresh water 20 'for the high-temperature disinfection process.
- This is not shown in this form in Figure 3, but is sketched in Figure 2 by a preheater 22.
- a heat exchanger 23 of the high-temperature disinfecting device 24 is therefore in constant thermal exchange with a heat exchanger of the preheater 23. With good thermal insulation, the heat energy required for the high-temperature disinfection and the system to be continuously supplied with heat is very small.
- the fresh water 20 is now added to the water utilization device 26, so that, as has already been described several times by way of example, PET bottles are rinsed.
- the waste water 2 is collected in the waste water collecting device 8 and via a pump 38 'is pumped into the neutralization ⁇ device 27th Neutralization proceeds as described for FIG. 2.
- the neutralized wastewater 2 ' is in the down ⁇ water treatment device passed 28, which by the pump 38' is indicated. It will now be taken to the effect ⁇ We, the waste water treatment apparatus 28 closer one.

- this condenser 15 gives off heat of condensation, which is used to heat the waste water 2 '.
- this condenser 15 gives off heat of condensation, which is used to heat the waste water 2 '.
- the waste water 2 ' is sent through the aforementioned heat exchanger 11, whereby it is further heated.
- a heat medium 4 may be in thermal contact with the waste heat of another industrial process 46th
- the waste water 2 is heated by the heat exchangers 11 and 10 to a temperature which is between 60 ° C and the boiling point of the waste water 2 '.
- the boiling point of the waste water 2 ' may be changed to the boiling point of pure water, depending on Geloes ⁇ th substances (acetic acid, peracetic acid, surfactants or nitric ze). Boiling temperatures between 95 ° C and 110 ° C can usually occur.
- the evaporator surfaces 34 are characterized in particular by the fact that they have a very large surface in relation to their base area.
- the capacitor device 14 are arranged capacitors 15 and 15 'whose response was ⁇ as already described. At the capacitors 15 and 15 ', the wastewater 2''condenses again to water, the is now germ-free and cleaned. It is discharged as purified water 44 from the condenser device 14.
- the purified water 44 can be subjected to a further measure of the high-temperature disinfection 24 and conducted via the detour as fresh water 20 "through the heat exchanger 11 to the water utilization device 26. Since the purified water is already virtually sterile in itself, it may be useful in various applications, a direct line, the broken lines in FIG 3 having 44 'is provided ⁇ , to lead to the water utilization device 26, and this purified water 44 feed directly back there. In this case, an energy-consuming high-temperature disinfection could be omitted.
