Abstract
The present invention relates to a plant having a storage tank for warm water for storing warm water, in particular warm water at a temperature of at least 60 DEG C; and a degassing appliance which is connected to the warm water storage tank and is designed to degas the warm water from the warm water storage tank in order to obtain degassed water.
Description
Technical field
What the present invention relates to degassed water provides scheme, and degassed water, in food and drink industry, especially uses when beer production.
Background technology
In food and drink industry, in many processing steps, all need water.In order to tackle the danger of corrosion pipeline and equipment, usually using degassed water, that is, there is no the water of the gas of the carbonic acid gas that the picture of dissolving is such as free or oxygen.Especially oxygen not only causes disadvantageous effect to facility and piping system, and affect food and drink can keeping quality and/or quality.
Especially, in beer production, in water, the least possible oxygen content is had to be worth expecting.But Raw material processing and wort and process for beer production are input in the product that will manufacture in a large number by causing oxygen.In order to this input is kept few as much as possible, must process especially the product water used and process water.The water that product water can be understood to be a part for final product (here namely beer) or the water come in contact with elementary/intermediates or the finished product, such as wash water.Process water is to produce and/or fill the necessary but water be not fed directly in the finished product of beverage.Process water such as can be understood to the isolated water of pump, water spray or the water for cleaning (such as, clean-in-place) facility and/or machine.Similarly, in food and drink industry, term service water is used.The water such as used in energy storage canister belongs to service water, and it uses for heat consumer to heat object in the system closed.Sometimes, term service use water is equivalently for term process water.With product water unlike, the water being called as service water or process water refers to the water do not come in contact with elementary/intermediates or the finished product.
In beer production, such as, all use degassed water in (in advance) saccharification with when washing wort, when pouring into tank and filtering system, when pipeline is discharged and when producing beer and closing to an end and dilute beer.Particularly for the degassed water for diluting (mixing), except the purity on chemical technology, less oxygen content is also significant.
The facility for cold degassed, the degassed and vacuum outgas of heat is known to by prior art.Cold degassed time for degassed water, need degas module and water cooler.When heat is degassed, additionally use for heating the heat exchanger with energy recovery.With cold degassed time differently, when heat is degassed, to degassed water carry out heating be mainly used to reduce bacterium.For this reason, the elementary energy of extra consumption calorifics is needed.When heat is degassed, remaining oxygen content can reach 0.01mg O
2/ l to 0.02mg O
2/ l, and cold degassed time, remaining oxygen content can reach 0.02mg O
2/ l to 0.03mg O
2/ l.The feature of two kinds of methods is all the relatively high consumption to rare gas element.Water to be de-gassed is cooler, just has more oxygen chemical combination or is dissolved in water to be de-gassed.Being dissolved in the oxygen in cold water, although after heating water in the scope that heat is degassed, being just purged in de-gassing vessel when using relatively a large amount of rare gas elementes.In addition, even if the degassed facility of known heat is provided with the device for energy recovery, but such as form still must be provided to be the elementary energy of steam.
Vacuum outgas without the need to carrying heat energy, but but has the similar high demand to rare gas element.But the remaining oxygen content in degassed water typically only drops to and is about 1.0mg O
2/ l.In addition, pasteurize is not carried out to degassed water, and there is the additional demand to the electric energy for generation of vacuum.
By in the known method of prior art, very high elementary energy is needed to drop into all the time.At this, utilize heat energy (such as steam) or realize this elementary energy input by dropping into electric energy (such as running refrigerating facility or the energy for generation of vacuum).Additionally, because rare gas element drops into (such as carbonic acid gas), thus the overwhelming majority incidentally creates considerable discharge.
In addition, the problem when heat is degassed is, in order to realize the energy efficiency high as far as possible of facility, must use water cool as far as possible.First this just makes to carry out input to the UTILIZATION OF VESIDUAL HEAT IN level of inside becomes possibility.At this, it is favourable for dropping into water cool as far as possible in view of energy recovery on the one hand, and the shortcoming existed on the other hand is that more oxygen or other aerification are combined in cold water.Cold water temperature depends on on-the-spot fresh water temperature.Therefore, these depend on geographical conditions equally for making the facility of water degasification, and this will show other shortcoming, and therefore make facility so efficient and flexible.If alternatively utilized temperature/heat water to make the degassed facility operation of traditional heat, so the consumption that the such as form for cooling degassed water is the energy of electric energy is just increased.
In principle, known for making the facility of water degasification be regarded as the system closed be made up of pipeline and heat exchanger, wherein, degassing tower shows as driving away less desirable gas, as unique possibility of such as oxygen.Based on the condition on these facility technologies, after UTILIZATION OF VESIDUAL HEAT IN, directly cold water is flowed to degassing tower and become degassed water.
Summary of the invention
Consider described prior art, task of the present invention is, provides a kind of for carrying out equipment degassed efficiently that is energy-conservation and/or low emission to the water such as using in food and drink industry.
Above-mentioned task solves by providing a kind of following facility, this facility has for storing warm water, especially having the storage tank of warm water of temperature and the de-gassing vessel of at least 60 DEG C, and this de-gassing vessel is connected with the storage tank for warm water and is configured to carry out degassed to the warm water from the storage tank for warm water.This facility can be for the production of and/or the facility of filling food or beverage.Storer for warm water can be configured to the warm water storer known by prior art of the identical or different temperature levels in brewery, beverage or food enterprise and/or hierarchy memory and/or multiple storage tank.Warm water has at least 60 DEG C, especially 75 DEG C to 85 DEG C, the especially temperature of 78 DEG C to 82 DEG C.Term warm water is included in the term hot water used in technical field.

Accompanying drawing explanation
Below with reference to the accompanying drawings the embodiment of facility according to the present invention is described.Described embodiment is only counted as illustrative and nonrestrictive in all fields, and contains the different combination of the feature enumerated in the present invention.In addition it is to be noted, in the accompanying drawings and do not describe due to the reason of general view in the description and show in addition a lot of for the adjustment link needed for foregoing invention, valve, pump or other e Foerderanlage or for measuring, the device of regulation and control technology.
Fig. 1 explanatorily illustrates the facility with the storage tank for warm water, the storage tank for cold water and the de-gassing vessel according to example of the present invention;
Fig. 2 explanatorily illustrates the facility with the storage tank for warm water, the storage tank for cold water, frozen water storer and the de-gassing vessel according to another example of the present invention.
Embodiment
Figure 1 illustrates the exemplary structural scheme (also see Fig. 2) for facility according to the present invention.The temperature exemplarily occurred is learnt by Fig. 1 and Fig. 2.Storage tank 1 for warm water stores (about 75 to the 85 DEG C) water arranged for degassed temperature.For in the storage tank 1 of warm water, pasteurize is carried out to warm water.By oxygen (O during resting in the storage tank 1 for warm water
2) drive away out from the warm water stored.Warm water to be de-gassed via pipeline 2 by unshowned pump delivery to de-gassing vessel 3.Therefore unlike the prior art, warm water is set for degassed, to obtain degassed water.When the barometric point of 1bar, in the water temperature of such as 15 DEG C, chemical combination has 10mg O
2/ l, and in the water temperature of such as 80 DEG C only chemical combination have 3.1mg O
2/ l.Therefore, warm water is set in order to degassed, to obtain degassed water, with to arrange compared with cold water this just can realize obviously simply, degassed efficiently.
The position of the pipe interface on various storer is only schematically illustrated in the accompanying drawing illustrated.Therefore can advantageously, warm water to be de-gassed is drawn out of in the region on the lower of the storage tank 1 for warm water, and (and via pipeline 2) flows to de-gassing vessel 3.Water (via pipeline 11) can be realized in the top region of the storage tank 1 for warm water to be deposited in the storage tank 1 for warm water.Top region can be arranged in the top half or top 1/3rd of relevant storage tank, and region on the lower can be arranged in relevant storage tank half on the lower or on the lower 1/3rd.At this advantageously, perhaps some cold water are to be deposited in the storage tank 1 for warm water lower than the temperature water level land existed in for the storage tank 1 of warm water, and therefore colder water occur based on thermal lift in for the storage tank 1 of warm water and mix with warmer water.Therefore, cold water is heated, and therefore can also more efficiently carry out degassed.In addition, water affects energetically to play this effect for the longer residence time in the storage tank 1 of warm water.Therefore, the water with the least possible oxygen content can be provided for de-gassing vessel 3.
When conventional heat is degassed, to de-gassing vessel conveying cold water, and there (when with atmospheric isolation) directly by cool water heating to degassing temperature.At this, being again cooled by water that is cold, that flow to de-gassing vessel through degassed water of temperature, and therefore, in the prior art advantageously, uses water cold to be as far as possible used for degassed, the UTILIZATION OF VESIDUAL HEAT IN of inside can be realized.But because the cold water provided has the temperature by place restriction usually, the accurate temperature therefore flowing to the water to be de-gassed of de-gassing vessel can not accurately control.On the contrary, the present invention is not by the dependent impact in place of (wanting degassed) cold water.
In addition, the facility of Fig. 1 is equally also that facility being described as the integral part of the facility for the production of beer of following Fig. 2.Should be understood that the present invention is not limited thereto, and relate to for the production of and any facility of filling food and beverage, in these facilities, use degassed water.
In brewery, such as brewage between the middle brewing water tank that exist warmer than the storage tank 1 for warm water is provided, and store the warm water of at least 60 DEG C, use as the water in wort cooler and/or pan smog condenser and heat in the mode of UTILIZATION OF VESIDUAL HEAT IN at this before this warm water.Alternatively, by other renewable energy source (such as central-heating station, solar generator facility), the warm water of the storage tank 1 for warm water is heated at least in part.Storage tank 1 for warm water also can be set to storage and have more than 85 DEG C, the accumulator of the water of the temperature of such as about 95 DEG C.
In the degassing tower of de-gassing vessel 3, as known by prior art, introduce (such as spraying or atomization) want degassed water.De-gassing vessel 3 can comprise the loading thing forming the large structure of surface change, such as, structurized Stainless Steel Helices as same known by prior art and/or Raschig ring (Rasching-Ring).De-gassing vessel 3 can have in degasser or all sides well heater (not shown) on side, and within this week, side well heater can be used for the thermal medium of answering steam or liquid state.Liquid thermal medium can from independent energy storage canister and/or the storage tank 1 for warm water.In order to improve the efficiency of degasification process, via rare gas element delivery section 4, rare gas element can be flowed to de-gassing vessel 3, rare gas element extrudes oxygen.Rare gas element can from top and/or side ground and/or flow to de-gassing vessel 3 from below.Carbonic acid gas or nitrogen such as can be used as rare gas element.Because the glassware for drinking water compared with prior art flowing to de-gassing vessel 3 has obviously higher temperature, therefore (if generally speaking) need less rare gas element.
In de-gassing vessel 3, carry out degassed water flow to the first heat exchanger 6 via pipeline 5, such as chip or tubular heater exchhanger, in order to cooling.Such as by the temperature of the degassed water cooling of the temperature of about 73 DEG C to 83 DEG C in the first heat exchanger 6 to about 7 DEG C to 22 DEG C.Cold water can be used as heat-eliminating medium in the first heat exchanger 6, this cold water temporarily stores in for the storage tank 14 of cold water and is transported to the first heat exchanger 6 via pipeline 10.Cold brewing water tank between such as can being set to brewage in brewery for the storage tank 14 of cold water.By the storage tank 1 for warm water take away can corresponding to the volume of water in order to cool degassed water taken away by the storage tank 14 for cold water in order to degassed volume of water, and finally by the storage tank 1 flowed to by pipeline 11 for warm water, thus have balanced water resources in for the storage tank 1 of warm water.
Perhaps can have far below the temperature desired when being supplied in the storage tank 1 for warm water at the water flowed to for the storage tank 1 of warm water passed after the first heat exchanger 6 as heat-eliminating medium.In order to the temperature making water be warmed to expectation, the second heat exchanger 12a can be provided with by streamwise before the storage tank 1 for warm water.The water of so heating further more effectively can carry out degassed now at the temperature that this is higher.Alternatively or additionally, be ahead of de-gassing vessel 3 ground and be provided with the 3rd heat exchanger 12b after the storage tank 1 for warm water, water to be de-gassed can raise or be adjusted to the temperature of expectation by the 3rd heat exchanger, therefore to make degassedly to become easy.Such as form can be used to be steam or high-pressure water heating (HDHW) elementary can as the thermal medium for optional heat exchanger 12a and 12b.Such as, second and the 3rd heat exchanger run with the energy of the recovery that such as can be provided by accumulator (EST).It is also feasible for being carried out combining by the energy of elementary energy and UTILIZATION OF VESIDUAL HEAT IN.
Second heat exchanger 12a and the 3rd heat exchanger 12b is optional, wherein, usually preferably, does not cancel the second heat exchanger 12a.Can realize by the second heat exchanger 12a, the water stored in for the storage tank 1 of warm water is not less than the temperature threshold limited in advance.In addition, the amount of the rare gas element that the Sopwith staff cun that can reduce de-gassing vessel 3 by arranging the 3rd heat exchanger 12b maybe will expend.
The degassed water through cooling such as can use in brewery or in food and drink enterprise as product water.Temperature between product water to be used and degassed water is had any different and usually will quality product be produced to adverse influence or be less desirable for the reason operating (Production Flow Chart).
For multiple different reason also it is to be expected that prepared relatively cold degassed water.Often need the relatively low temperature of about 0 DEG C to 5 DEG C for use as product water through cooling and degassed water.Therefore, in example shown in Figure 1, will be cooled to the temperature expected by the 4th heat exchanger 7 by the degassed water that the cold water supplied by the storage tank 14 being used for cold water cools by the first heat exchanger 6, such as, be 2 DEG C to 5 DEG C.The heat-eliminating medium of the 4th heat exchanger 7 is supplied by unshowned refrigeration facility.Refrigeration facility utilizes circulation loop 8 to run, and ethylene glycol guides via this circulation loop as cold carrier.Also other cold carrier/refrigeration agent/heat-eliminating mediums can be used to replace cold carrier ethylene glycol.
As to provide by refrigeration facility work the 4th heat exchanger 7 alternatively, as shown in Figure 2, the first heat exchanger 6 can use frozen water from frozen water storer 15 as heat-eliminating medium.As to the cold water of the storage tank 14 for cold water alternatively, frozen water can be used or can use in the first heat exchanger 6 as heat-eliminating medium together with cold water.Frozen water storer 15 also can be set up the storer 14 replaced for cold water shown in figure 2.Shown in figure 2 in embodiment, frozen water storer 15 may be used for supplying unshowned wort cooler.
Under any circumstance, degassed and optionally through cooling water other make use before can be stored in for degassed water storage tank 9.Degassed water possible makes use comprise use as cold melanism water, this is because show, cold wheat juice of washing is favourable on energy.But as it is such as stored in the storage tank 14 for cold water, cold water has too much oxygen.On the contrary, the degassed water through cooling can advantageously use as melanism water.In addition, the degassed water through cooling can also be used in order to dilute beer.
Show the memory buffer 9 for storing degassed water in fig. 1 and 2, but also such as can be provided with multiple memory buffer before and after the first heat exchanger 6 or before and after the 4th heat exchanger 7, in these memory buffer, temporarily can store differing temps degassed for different application targets and optionally through the water of cooling.
Degasification process in de-gassing vessel 3 can be supported by producing negative pressure.The boiling point of water to be de-gassed can be reduced by negative pressure, thus, can realize better degassed in de-gassing vessel 3.In order to produce negative pressure in de-gassing vessel 3, can use water jet pump 13, this water jet pump can be connected to the pipeline of arbitrary water guide in principle, such as, be the pipeline for cold water.In the example illustrated in fig. 1 and 2, water jet pump 13 is such as connected to be supplied on the pipeline 10 with heat-eliminating medium to the first heat exchanger 6.Because this cold water is transported in the storage tank 1 for warm water after heating further in optional second heat exchanger 12a if desired, so rest on for the time durations in the storer 1 of warm water at warm water, the oxygen be contained in cold water has carried out degassed again, and therefore, the water had with as do not introduced oxygen content identical oxygen by water jet pump 13 is flowed to de-gassing vessel 3.
In addition can advantageously, water jet pump 13 is such as connected in the pipeline (not shown) of the storage tank 14 flowed to for cold water.When filling the operation in order to de-gassing vessel 3 to the storage tank 14 for cold water simultaneously, water jet pump 13 can be used.In addition, can carrying out filling simultaneously and can provide other the tanks various of suitable vacuum, be also applicable as such as tubular type water pot.
