Definitions

  • the invention relates to a method for the simultaneous cleaning of a plurality of pipelines or piping systems, each with different line cross-sections, wherein the cleaning is carried out with a liquid cleaning medium, which is removed by means of a feed pump a collection and fed to the systems to be cleaned and a device for performing such a method.
  • the first CIP systems supplied the cleaning media (temperature and concentration) in a fixed sequence and duration, which was determined by a program stored in the CIP system.
  • the cleaning medium was pumped through the system to be cleaned during the cleaning process, but then passed into the sewage system. This process is referred to as "lost" cleaning because the cleaning medium is not reused.
  • the so-called CIP circulation cleaning was developed with a "stacking" of cleaning solutions, whereby the cleaning media (usually caustic and / or acid solutions) return to the CIP via lines and are reused there, as the cleaning power is sufficient.
  • the invention is therefore based on the object, the above-mentioned and previously described method and a corresponding device for cleaning of lines in such a way and further, that the amount of cleaning medium required and the cleaning time can be minimized without affecting the aseptic conditions.
  • the object is achieved according to a first alternative in that the cleaning medium flow is supplied to the first system to be cleaned and is divided after leaving the first system to be cleaned into two partial streams, of which a partial flow for cleaning the second or further system is used and the other partial flow is returned to the sump.
  • the object is achieved in that a cleaning medium stream is first supplied to the second or further system to be cleaned and then divided into partial streams, one of which in turn is mixed with the second partial flow and the other is returned to the sump.
  • the cleaning medium stream is first divided into two partial streams, of which the first is returned to the collecting container and the second cleaning medium initially in streams one of which is supplied to the second or further system to be cleaned and the other to the collecting container.
  • the alternative modes of operation described are particularly useful since they can be achieved alternately without constructive extension or circuit complexity.
  • the second or further system to be cleaned is associated with a delivery pump, whose direction of rotation for selecting the two alternative methods described must merely be reversed.
  • a corresponding device is characterized in that a second or further system to be cleaned is associated with a feed pump whose speed and direction of rotation for determining or regulating the cleaning process can be changed, that the line for the first partial flow is designed as Druchhalteaji and in that a throttle valve is arranged in the return line of the partial flows.
  • the rotational speed of this pump and thus the volume flow of the cleaning medium can be varied in both directions in order to achieve an optimum cleaning effect.
  • the second or further system to be cleaned associated pump can be used both for conveying the cleaning medium and for conveying the product. This is particularly advantageous because - vice versa - especially at the retrofitting of a device according to the invention an existing pump can be used for the cleaning process with.
  • control of the flow rate of cleaning medium via the speed control of the two pumps in CIP system and the system to be cleaned.
  • the cleaning medium stream is first divided into two partial streams before entering the first system to be cleaned, of which the first is returned to the collecting container and the second is supplied to the first system to be cleaned.
  • the cleaning medium stream is first divided into two partial streams before entering the first system to be cleaned, of which the first is returned to the collecting container and the second is supplied to the first system to be cleaned.
  • By reducing the first partial flow it is possible to influence the temperature, concentration or amount of the cleaning medium for the main flow to be carried out for the purification of the systems.
  • the inventive method is in this case particularly economical with respect to the cleaning medium, since the branched first partial flow can (re) be used in a lack of cleaning medium in the systems to be cleaned for refilling the cleaning system.
  • the clearing (Lauge- / acid concentration) of the cleaning medium is adjustable.
  • the CIP system can be equipped with several collection tanks for different cleaning media. This is sufficiently known from the prior art and should therefore apply correspondingly to the method according to the invention or the corresponding device, without it being necessary to refer to it in detail.
  • the device according to the invention can also be used, in particular, when the line cross sections of the systems to be cleaned are of different sizes. Due to the line circuit according to the invention a simultaneous cleaning of two or more systems with different skillssmengen or nominal sizes is independent of the delivery rate of the feed pump of the CIP system possible.
  • the device according to the invention preferably has sensors for measuring the volume flows and / or for measuring the temperature or conductivity.
  • 'conductivity' is meant the acid / alkali concentration of the cleaning medium.
  • Fig. 1 shows how a cleaning medium is conveyed by the CIP system with at least one sump 1 and a feed pump 2 via the flow line 3 in the direction of subsystem A. Via a bypass 4, a partial flow TS1 is returned to the return line to the CIP system. This current is used in case of medium deficiency in the subsystems for refilling.
  • Partial flow TS3 is returned via line 8, which serves as a bypass here, to line 6 between subsystem A and subsystem B (internal circuit).
  • Partial flow TS4 flows back via a throttle 12 to the CIP system. This amount, which leaves the subsystems A, B and B ', decides on the amount of feed of fresh cleaning medium in the subsystems A, B and B' from the CIP system.
  • the remaining partial flow TS2 passes via a line 5 in the subsystem A to be cleaned and from there as partial flow TS2 'via a line 6 on in the subsystem B. Dashed indicates that there are in addition to the subsystem B also to be cleaned subsystems B' can.
  • feed pump 7 provides the necessary flow of the cleaning medium, supported by the feed pump 2 of the CIP system.
  • the substream TS2 'before entering the subsystem B is combined with the further substream TS3 already passed through this system, which is led back into the line 6 via a line 8.
  • a previously separated amount of the cleaning medium is supplied as a partial stream TS4 again to the collection container 1 via the lines 9 and 10.
  • a pressure holding unit 11 and in line 12 a throttle valve are provided in the line 4.
  • the two subsystems A and B can have different sizes. Due to the fact that the part of the system A already left partial flow TS2 'may enter the subsystem B or B', the reverse case is excluded, it is reliably avoided that in the lines with a larger nominal size of the subsystems B or B. 'lumpy material located in the subsystem A can promote and lead there to blockages.
  • the partial flow TS2 leaves the subsystem A to be cleaned as partial flow TS2 'and is conducted via the line 8 and then again divided into the partial flows TS3 * and TS4 *.
  • the partial flow TS3 * is used to clean the subsystems B (or before already used B ') and the partial flow TS4 * fed back to the sump 1.
  • the substream TS3 * is mixed back into the substream TS2' via the line 6.
  • Fig. 3 and 4 are identical in content to the Fig. 1 and 2 However, for better understanding, for example, the flow rates with the unit volume / time (m 3 / h) are also shown.
  • the cleaning medium leaves in the example shown (both alternatives), the feed pump 2 of the CIP system with 7 m 3 / h and is further promoted after the first division in 2 m 3 / h as partial flow TS1 and 5 m 3 / h as partial flow TS2.
  • a further partial flow TS3 (20 m 3 / h) of the cleaning medium which has already passed through the subsystems B and possibly B', initiated, so that a total flow of 25 m 3 / h, which is introduced into the subsystems B and possibly B '.
  • the feed pump 7 ensures for a constant delivery of the illustrated example 25 m 3 / h.
  • the delivery flow below the feed pump 7 is divided into the substreams TS3 (20 m 3 / h) and TS4 (5 m 3 / h), wherein the substream TS4 (5 m 3 / h) together with the substream TS1 (FIG. 2 m 3 / h) with an amount of cleaning medium of 7 m 3 / h to the CIP system dissipated.
