Description

TECHNICAL AREA

The The invention relates to a method according to claim 1, a method according to claim 2 and an arrangement according to claim 9th

It is about procedures and an arrangement for the operation of tank storage systems in the solid-lined composite with pipe systems for liquids, in particular for Application subject to high microbiological quality requirements Equipment for product processing and product transfer in the food industry and beverage industry, of pharmacy and biotechnology, where the fluids from the pipe system a tank of at least one tank existing Tank storage system supplied or where the liquids be discharged from a tank in the pipe system.

An arrangement of the generic type, which today belongs to the most widely used prior art, is in WO 02/066593 A1 with reference to the local there 1 described and explained in detail. This piping concept described there is often insufficient to meet today's ever-increasing microbiological quality requirements. As microbiological stress measurement methods are improved and detection limits for substances of all types are reduced, the microbiological demands placed on food and beverage, pharmaceutical and biotechnology manufacturing facilities are also increasing.

• • Hinter dem Verteilpunkt eines Ventils sind Rohrleitungsteile nachgeschaltet, aus denen üblicherweise das Produkt nicht ausgeschoben werden kann.

• • Um in den in Rede stehenden klassischen Ventilmatrizes Bereiche unausgeschobenen Produktes zu vermeiden, die Produktverluste zu verringern und diese Bereiche auch bei gefülltem Tank separat reinigbar zu machen, ist ein großer Aufwand in der Peripherie der Ventilmatrizes erforderlich, der in den meisten Fällen aus Kostengründen nicht realisiert werden kann und der sich, falls er denn vorgesehen ist, in der Regel unübersichtlich und wartungsunfreundlich gestaltet.

Piping systems, as described in WO 02/066593 A1 as prior art, have as core elements so-called. Centralized valve matrices, such arrangements undoubtedly have the following disadvantages:

• • Behind the distribution point of a valve piping parts are connected downstream, from which usually the product can not be pushed out.
• • In the aforementioned "dead ends" often an undefined mixture of different products and Ausschubwasser.
• • This undelivered product will be lost at the latest during subsequent cleaning.
• • Undefined product mixtures, depending on their composition, cause a negative impact on the product because uncontrolled processes can occur. This can lead to unwanted germ growth.
• • In addition, hot cleaning processes in the valve turrets create an environment that promotes germ growth.
• • Especially in horizontal valve blocks and long tank outlet lines, the product contained therein does not participate in the processing process in the tank. There is thus no or only a very small mass transfer in these areas.
• • In order to avoid areas of unexpelled product in the classic valve matrices in question, to reduce product losses and to make these areas separately cleanable even when the tank is full, a great effort is required in the periphery of the valve matrices, which in most cases is not cost-effective can be realized and, if it is intended, usually made confusing and maintenance-friendly. In practice, this fact leads to compromise solutions with more or less pronounced limitations.
• • Air that has entered the tank outlet pipes and the valve crossbeams prevents proper cleaning of the piping system.

The disadvantages of the piping systems with centralized valve matrices described above are largely avoided by a piping system, if it according to the proposed WO 02/66593 A1 and evidenced by the DE 10 108 259 C1 protected teaching is designed. This consists of at least one tank storage system is in communication with a consisting of at least one pipe system, each one in a tank bottom of the respective tank ausmündender valve manifold is provided, which is formed as an elongated hollow body which is oriented substantially perpendicular and the connection openings for connecting owns its interior with each of the pipelines. In this case, in each connection between the pipe and the associated connection opening, a valve configured in its seat so as to be secure against mixing is arranged, which switches this connection in the immediate vicinity of the hollow body. The application of this piping system is applicable without having to operate a disproportionate effort in the periphene of the tank farm.

All previously known piping systems are designed and configured such that the nominal diameter of the pipes connecting the production sites and the fittings arranged in these is determined by the exchanged between the production plants volume flows and other delivery conditions. Accordingly, the size will be large end pipes and the functional valves in the tank storage system dimensioned, which is connected to the transfer lines interconnecting the production sites. As a rule, the tank-related valves and the tank-related piping are regularly oversized due to this dimensioning approach. This overdimensioning causes additional costs, without there being a technological equivalent in return.

INVENTION

It Object of the present invention, method of the generic type and an arrangement for implementation to create the procedures that allow the piping system in the field of connection lines and functional fittings of the Equip tanks with smaller sizes than previously required.

These Task is for a tank storage system, the liquid supplied is achieved by a method having the features of claim 1, while the Task for a tank storage system, from the liquid dissipated is achieved by a method having the features of claim 2. Advantageous embodiments of the proposed method are Subject of the dependent claims 3 to 8. An arrangement for carrying out the respective method arises from the features of claim 9.

The basic procedural idea of the invention consists in the flow division in front of the tank storage system into two separate partial flows. These make it possible to dimension the function lines and fittings in a smaller nominal diameter than hitherto usual. Assuming the condition that the respective flow velocity of the two separate partial flows of the flow velocity of the undivided volume flow should approximately correspond, then it follows at approximately equal partial flows, that the respective reduced nominal diameter for the partial flows at about 70% (corresponds to √ 2 / 2) of the nominal output diameter for the undivided flow. With a nominal nominal diameter DN100 for the undivided flow, this means that the nominal diameter of the pipeline branches receiving the approximately equal partial flows is purely mathematically about 70 mm. In this case, a nominal diameter of DN80 would be chosen, so that the flow rate of the partial flows in the associated piping branches is even slightly lower than in the piping systems of the prior art.

The Principle of flow division will affect both the hydration to the tank storage system, i. on the filling of a tank, as well on the emptying of the tank storage system, i. on the emptying a tank, applied. In case of filling the respective tank is the supplied liquid at a particular, for all tanks of the tank storage system relevant branching point in two separate partial streams divided up. These separated partial streams are separated from each other transported to the tank and before entering this at one of the tank associated association office united. All unions are an integral part of an outgoing from the branch point, in closed annular flow path first kind.

at the liquid discharge from the tank storage system, i. when emptying a tank, the to be removed from the respective tank liquid after emerging from this at a branch point assigned to the tank in two separate partial streams divided up. These separated partial streams are separated from each other to a certain, for all Tanks of the tank storage system authoritative Union office transported, united there and subsequently dissipated. All Branching points are also an integral part of a from the union point outgoing, self-contained annular flow path second kind.

A Arrangement for performing of the two independently to be realized from each other, briefly outlined above method is characterized by the fact that the pipe leading directly to the tank first type of filling one for all tanks relevant Branching point, from which the pipeline respectively branches into a first and a second pipeline branch of the first type for filling, and that the pipe leading directly to the tank second Type for emptying a for all tanks relevant Unification point, from which this pipeline each in a first and a second pipe branch second Type branched for emptying. The associated pipe branches first Type of filling and second type for emptying are each in the form of a loop together and the tank (s) is (are) over one (these) each associated association office or a branch office to the each associated ring line connected.

The proposed method and the arrangement for their implementation procedural and biological benefits, because dead ends avoided and product and liquid dispensers and cleaning operations more optimal are shaping. This contributes to losses and critical zones the cleaning avoided, this advantage in a special way then achieved if, as this is another variant of the method provides for additions or reductions liquids one with the respective tank contents in direct connection flow through the space below the respective tank and the respective liquid in this room in the immediate vicinity to its inner boundary of the piping brought up to this space of the pipe system optional, switchable and mix-proof removable is.

In the case, that leading to the respective tank Pipe branches, the part streams transport, are very different pressure loss, because these pipeline branches For example, they differ extremely in their length, one sees Process variant before that the distribution ratio between the partial streams through their respective throttling is adjustable.

A other related Process variant proposes in this regard, that the division ratio between through the partial streams their respective flow control is adjustable.

The complete emptying of the tanks 1.1 to 1.n is signaled in each case via a level message LL (low level) and in the first pipeline of the first kind for filling 2.1.1 , in front of the tank 1.1 , and in the first pipe of the second kind for emptying 3.1.1 , behind the tank 1.1 , in each case a flow meter FT is arranged.

2 to 6 (Invention):

In 2 is that in 1 already shown tank storage system 1 with his tanks 1.1 to 1.n ( 1.1 , ..., 1.i , ..., 1.n ) equipped with the inventive arrangement. In the area of the respective tank outlets, the piping corresponds to that according to 1 , wherein according to the invention the nominal diameters are reduced by at least one nominal width. The crucial inventive idea now is that filling the pipe system 2 . 2.1 on a specific, for all tanks 1.1 to 1.n of the tank storage system 1 relevant branching point [VZ-Sj], in the present case a first branching point VZ-S1, in the first pipeline of the first type for filling 2.1.1 into a first pipeline branch of the first type for filling [ 2.i.1a ] 2.1.1a and a second pipeline branch of the first type for filling [ 2.i.1b ] 2.1.1b branched. These pipe branches of the first kind [ 2.i.1a ] 2.1.1a and [ 2.i.1b ] 2.1.1b are in the form of a loop of the first pipeline of the first type for filling [ 2.i.1a - 2.i.1b ] 2.1.1a - 2.1.1b merged, with the respective tank 1.1 to 1.n via an association point [VEi.i-Sj] assigned to it in each case, in the exemplary embodiment VE1.1-S1 to VE1.n-S1, to the respectively assigned ring line 2.1.1a - 2.1.1b connected. The aforementioned merging point VE1.1-S1 to VE1.n-S1 is formed by an associated valve V1.i-Sj], in the present case the valve V1.1-S1 to V1.n-S1. The over the first pipeline of the first kind for filling 2.1.1 brought liquid filling Pk, in the present case, the liquid filling P1, at the first branch point VZ1-S1 in a first part stream [Pk.1], P1.1 the liquid Befül ment P1 and a second part flow [Pk.2], P1 .2 the liquid filling P1 split. These partial flows P1.1 and P1.2 arrive via the respectively assigned pipeline branch of the first type for filling 2.1.1a and 2.1.1b to the tank in question 1.1 to 1.n to be filled at the junction [VE1.i-Sj], for example the junction VE1.1-S1 of the tank 1.1 , combined and as a total flow the tank 1.1 to be fed. All combining points VE1.1-S1 to VE1.n-S1 [VE1.i-Sj, general] are an integral part of one of the branch point [VZ-Sj], in the present case of the first branch point VZ-S1, outgoing, in closed annular flow path Sj first type, in the present case, the first annular flow path S1.

The pipe system emptying 3 . 3.1 has in its first pipeline of two types for emptying 3.1.1 emptying the first pipe system 3.1 a union point [VE-Sj + 1] on, in the present case, a first junction V2-S2, from which the first pipeline of the second type for emptying 3.1.1 each into a first pipeline branch of the second type for emptying [ 3.i.1a ] 3.1.1a and a second pipeline branch of the second type for emptying [ 3.i.1b ] 3.1.1b branched. The associated pipe branches of the second type for emptying [ 3.i.1a ] 3.1.1a and [ 3.i.1b ] 3.1.1b are in the form of a loop of the first pipeline of the second type for emptying [ 3.i.1a - 3.i.1b ] 3.1.1a - 3.1.1b merged and each of the tanks 1.1 to 1.n is a branch point [VZ1.i-Sj + 1] assigned to it, in the present case the branch point VZ1.1-S2 to VZi.n-S2, to the assigned loop [ 3.i.1a - 3.i.1b ) 3.1.1a - 3.1.1b connected. The branch points VZ1.1-S2 to VZ1.n-S2 are respectively formed by the associated valve V1.1-S2 to V1.n-S2 (V1.i-Sj + 1, general). In turn, all the branching points VZ1.1-S2 to VZ1.n-S2 are thus an integral part of a self-contained annular flow path Sj + 1 of the second type, originating from the junction VE-Sj + 1, in this case the first junction VE-S2 present case of the annular flow path S2 of the second kind.

The one of the tanks 1.1 to 1.n Drained liquid draining Pk + 1, here the liquid draining P2, branches if tank 1.1 , is emptied, as shown by way of example, at the branch point VZ1.1-S2 in the first partial flow P2.1 (Pk + 1.1) of the liquid P2, which makes its way through the first pipe branch of the second type for emptying 3.1.1a takes, and the second partial flow P2.2 (Pk + 1.2) of the liquid P2, which via the second pipe branch of the second type for emptying 3.1.1b flows.

In the 2 which are not yet referred to in detail (A1, 2.1.4 , V7, V8, V9, V10, V11, V12, W4), are still in the following 2a to 6 explained. A thirteenth valve V13 switches a third pipeline of the first type for filling 2.1.3 opposite the eleventh valve V11. Valves V14, V15 and V16 in the first pipe system drain 3.1 correspond to the valves V11, V12 and V13 in the first pipe system filling 2.1 , A fifth water outlet W5 is via a second pipeline of the second type for emptying 3.1.2 brought to the valve V14 and a second Ausschub A2 is via a fourth pipeline of the second type for emptying 3.1.4 connected to valve V15.

The in 2 Z1 marked first flow divider area is in 2a shown modified and marked as a second flow divider region Z2. A seventh valve V7 forming the first branching point VZ-S1 is provided with a first position transmitter 5.1 provided by means of which the passage cross section of the seventh valve V7 verän can be changed. At the beginning of the second pipe branch of the first kind for filling 2.1.1b an eighth valve V8 is provided, which is a second position transmitter 5.2 to change the passage cross-section of the eighth valve V8 has. By means of the position transmitter 5.1 and 5.2 According to the invention, the distribution ratio between the partial flows filling P1.1 and P1.2 can be adjusted by their respective throttling. Similarly, the first junction VE-S2 through a ninth valve V9, which is a third position sensor 5.3 has, configured, and at the beginning of the second pipeline branch of the second type for emptying 3.1.1b is a tenth valve V10 with a fourth position sensor 5.4 provided, so that the distribution ratio between the partial flows emptying P2.1 and P2.2 in the annular flow path S2 of the second type by the respective throttling these partial flows emptying P2.1, P2.2 is adjustable.

In 2 B is shown within a third flow divider region Z3, another embodiment of the invention flow separation. In contrast to the arrangement according to 2a here is the distribution ratio between the partial flows filling P1.1 and P1.2 or emptying P2.1 and P2.2 not by position transmitter 5.1 to 5.4 but through a flow control 6.1 to 6.4 realized. This means that the sub-streams P1.1 and P1.2 or emptying P2.1 and P2.2 which can be set by the relevant actuators, the valves V7 to V10, are detected in their actual state via the flow meter FT and the difference between a desired value and the actual value for controlling the respective division ratio is used.

A filling of the tank 1.1 of the tank storage system 1 with liquid filling P1 (Pk) shows 3 , The tank 1.1 liquid P1 to be supplied is filled via the first pipe of the first type 2.1.1 of the first pipe system filling 2.1 introduced and branches at the first branch point VZ-S1, the seventh valve V7, in the separate partial flows filling P1.1 and P1.2, on the way over the first pipe branch of the first kind for filling 2.1.1a and the second pipeline branch of the first kind for filling 2.1.1b to the union point VE1.1-S1, formed by the valve V1.1-S1, arrive, be united there and together in the tank 1.1 enter. Correspondingly, in the same way, filling takes place, for example, of the tank 1.n ,

At the end of the filling of the tank 1.1 is the first pipe system filled with liquid filling P1 (product) 2.1 , consisting of the first pipe of the first kind for filling 2.1.1 , the piping branches of the first type for filling 2.1.1a and 2.1.1b and filled with the candidate area of the valve manifold tree B1 with liquid P1. A discharge of the liquid filling P1 from the above-defined first pipe system filling 2.1 shows 4 , For this purpose, the first pipe of the first kind for filling 2.1.1 via a third water outlet W3 and a second pipe of the first type to be filled 2.1.2 in each case water W is supplied via a fourth water outlet W4. The third water discharge W3 takes its way via the seventh valve V7 in the first pipe branch of the first kind for filling 2.1.1a and the fourth water discharge W4 passes through a twelfth valve V12 in the second pipe branch of the first kind for filling 2.1.1b , The liquid filling P1 is thereby from the piping branches of the first kind for filling 2.1.1a and 2.1.1b on the way through the junction VE1.1-S1, formed by the valve V1.1-S1, supplied there, and then in the tank 1.1 ejected. A device connected to the distributor tree B1 for determining a quality signal (eg density or turbidity), which, however, is not shown, signals the transition between liquid P1 and water W of the extension W3 or W4, so that the ejection process can be ended.

While in the 2 to 4 the pipe branches of the first kind for filling 2.1.1a and 2.1.1b , flowing through each of the first branch point VZ-S1, is provided according to a procedural embodiment, as this 5 represents that the first annular flow path S1 of the first kind in case of need, for example in the course of cleaning the first pipe system filling 2.1 (Pipe cleaning filling line R1) or ejection of water W from this in a first Ausschub A1 (fourth pipe of the first kind for filling 2.1.4 ) in the environment, starting and ending in the first branch point VZ-S1, is flowed through in one direction. In the present case, the cleaning agent R of the pipe cleaning filling line R1 passes through the first pipe of the first type for filling 2.1.1 to the first branching point VZ-S1, from there via the eighth valve V8 into the second pipeline branch of the first type for filling 2.1.1b , Passes the valves V1.n-S1 to V1.1-S1, to then in the first pipeline branch of the first kind for filling 2.1.1a to arrive and via the seventh valve V7 an eleventh valve V11 and there via the fourth pipe of the first kind for filling 2.1.4 be supplied to the first Ausschub A1. The annular flow path S1 of the first kind is thus dead space-free in the flow, in a continuous direction to clean.

Analogously, in the same way, the annular flow path S2 of the second kind, formed by the first pipe branch of the second type for emptying 3.1.1a and the second pipe branch of the second type for emptying 3.1.1b , each starting from the first junction VE-S2, formed by the ninth valve V9, clean in the flow (detergent R of the pipe cleaning draining R2).

Finally shows 6 the discharge of water W, if before the first pipe system filling 2.1 for the purpose of flushing in the wake of a pipe cleaning filling line R1 was filled with water W. The discharge of the water W takes place in the present case by the liquid filling P1, which via the first pipe of the first kind for filling 2.1.1 the first branch point VZ-S1, formed by the seventh valve V7, is supplied. From there the liquid filling P1 (product) passes on the way via the eighth valve V8 into the second pipeline branch of the first kind for filling 2.1.1b and drives there the water W of the fourth water discharge W4 (see 4 ) and the water W of the third Wasserausschubs W3 in the subsequent first pipe branch of the first kind for filling 2.1.1a in turn until the total auszuschiebende water W has again passed the first branch point VZ-S1 and passes through the eleventh valve V11 and the first Ausschub A1 in the area. A device for generating a quality signal QS between the seventh valve V7 and the eleventh valve V11 signals the transition between water W and liquid filling P1, so that the Ausschubvorgang can be terminated.
