Definitions

  • This application describes a novel system for simultaneous automatic cleaning of several parallel pipelines by means of a propellant, preferably the operating medium, e.g. go through a condensation heat exchanger and a heat exchanger, without hindering the operation of other pipes in the system.
  • a propellant preferably the operating medium, e.g. go through a condensation heat exchanger and a heat exchanger, without hindering the operation of other pipes in the system.
  • a piggable multi-pipe system is particularly important for heat-transferring systems in which wall adhesions are to be expected, since in this way larger heat transfer rates can be achieved with a still acceptable number of lines and line lengths.
  • the present application provides a device that allows multiple pipes to be cleaned simultaneously without affecting the operation of non-cleaning mode pipelines.
  • the system is based on reconnecting several lines at the beginning and end of the system through the device into a manifold, e.g. also in conventional heat exchangers is the case.
  • the entire piping system is equipped with several devices. For example, four lines are each merged at their end into one device. For a sixteen pipe line system, eight devices are needed.
  • the abovementioned pressure drop in the single line is prevented by blocking the outflow to the collecting line through the pig so that the fluid pressure does not fall off for the pigs remaining in the pipe system.
  • the pig assumes the function of a valve according to the invention after its cleaning passage at the end of the individual pipeline.
  • the device for simultaneous pigging of individual lines is applicable to piping systems whose beginning and end are not spatially close. At both ends of the piping system there is a distributor or a sorter device, which distributes the fluid flow over several tubes or brings the fluid flow back together onto a tube.
  • the device is equipped with the corresponding inlets and outlets, their shut-off devices.
  • the pig storage station functions in the device at the same time as a shut-off device during the cleaning mode.
  • the piping system may consist of several units constructed in this way.
  • the pipes are directed towards and in genraum the fluid stream purified. At least one additional pump (pig pump) is used as the drive for the pigs, since the cleaning process must be disconnected from the normal conveying operation.
  • the cleaning of the pipeline in both directions is made possible by connecting the pig pump to both ends of the pipeline system.
  • a propellant for the pigs the medium conveyed through the pipeline is preferably used, other propellants are also possible.
  • the adhesions released from the pipe wall by the pigging process can be collected separately.
  • the device consists of a manifold or collecting pipe and the necessary inflows and outflows, which in turn are all lockable.
  • the first outlet is required for the inlet or outlet in normal operation.
  • the second outlet drains the propellant and the debris from the cleaning process and the third outlet is the port for the propellant of the cleaning mode pig.
  • a positioning unit which also takes over the pig detection via a switching contact exists.
  • the pigging operation in the direction of flow of the pumped liquid is initiated by a shut-off of the inlet and the collection process for the normal production operation at the other end of the pipe system.
  • the valves of the pipeline to the pig pump and to drain off the dirt at the end of the pipeline system are opened.
  • the line for the discharge of the driving medium for the pigging in the reverse direction remains closed.
  • the pig pump starts and builds up pressure behind the pigs so that they are driven through the pipeline. The dirt released by the pig can then be separated and removed.
  • a pigging operation against the fluid flow direction is initiated by shutting off the inlet for the normal conveying operation and in this case the collecting pipe at the opposite end of the pipeline system.
  • the valves for supplying the propellant and their derivative at the opposite end of the piping system At the end of the cleaning process, when all pigs have reached their destination, these valves close again and the valves for the distribution and collection of the pumped liquid are opened again and normal operation can be resumed.
  • the end of a cleaning process is determined by monitoring the arrival of the pigs in the individual lines, so that it can be controlled by the cleaning rhythm of the entire system.
  • the device in the first exemplary embodiment in Figure 1 for the simultaneous automatic cleaning of pipes according to the invention consists of a manifold or manifold (1) for the normal production operation and a collection chamber (2) for the pigging operation of the pigging pipes (3).
  • the manifold or manifold (1) is provided in this embodiment with a piston (8) as a deporting device.
  • a device for braking the pigs (7) At the end of the pipes (2) to be lumbered there is a device for braking the pigs (7).
  • This pig brakes (7) can be designed to detect the pig also as a registration unit.
  • Figure 1 shows in a schematic embodiment, the slide positions of the device for parallel simultaneous cleaning of pipelines in ISf ormal memori.
  • the fluid to be demanded flows through the tubes (3) into the bore (11) as an extension of the tubes (3) of the device and is distributed or rejoined in the device into a collecting tube (1).
  • Figure 2 shows the slide position during the pigging process at the starting point of the pigs.
  • the slide of the line (4), which leads the fluid to the pig is opened and the piston (8) closes the openings (10) of the bore (11) to the manifold (1).
  • the pig pump starts pumping the fluid for the pigging operation
  • the pigs (9) are driven by the build-up pressure behind the pigs (9) through the bore (11) and the pipes (3).
  • FIG 3 shows the individual segments of another variant.
  • This valve variant works on the same principle as in Figure 1 and 2.
  • the two variants differ only in the organization and control of the inflow and outflow
  • This variant consists of three holes (9a-c).
  • provided plates (12a-c) 5 take over the various tasks in the valve.
  • the bores (9a) represent the end of the pipes to be piggyback (2)
  • the holes (9b) are the cylinders for the pistons (11) take over the tasks of the valves (3, 4, 5) of the first exemplary embodiment
  • the holes (9c) are the collecting pipes for the inlets and outlets of the fluid used and the propellant for the pigging operation as the manifold (1) in the first exemplary embodiment.
  • the plates are superimposed as shown in Figure 4 so that the holes (9a-c) are hydraulically connected to each other via the holes (10a-c), so that a connecting line between the plates is formed.
  • the holes (9a) terminate the fluid-carrying lines (2) of the piping system to be lulled.
  • the fluid as well as the propellant for the pig then flows through the holes (10 a), which are considerably smaller but designed in multiple numbers than the medium-carrying lines, so that the pig can not leave the pipeline, through the holes (10 b) and (10c) to its destination or it flows in reverse from its reservoir via this path into the piping system, depending on whether the device is at the end or at the beginning of the piping system.
  • hn pig mode are at the starting point of the pig through the piston 11 in the lines 9.1b and 9.2b, the compounds 10.1b and 10.2b sealed, so by a second pump in addition to the pump for normal operation, via the connection 10.3 a the pigs of the lines 9a can be driven.
  • the pig comes to a standstill via the connecting line 9.2b and seals off an outflow, so that the pigs running in parallel, which have not yet reached their destination, are driven to their destination by a reduced cross-section in the pipeline system (2) to be pigged.

Abstract

Dispositif qui permet le nettoyage de systèmes à plusieurs conduites tels qu'ils sont utilisés par ex. dans des échangeurs de chaleur, à l'aide d'écouvillons. Ce dispositif permet en outre le nettoyage de plusieurs conduites simultanément. L'avantage de la présente invention est que les conduites peuvent être groupées à travers ledit dispositif, ce qui permet un nettoyage partiel de quelques conduites du système sans interruption du processus d'écoulement du fluide. Ledit dispositif est basé sur le fait qu'il sépare à l'aide d'un mécanisme de réglage le flux de milieu d'entraînement pour l'écouvillon du flux de fluide et sur le fait que les écouvillons utilisés empêchent, sur le site cible, l'écoulement du milieu d'entraînement, ce qui augmente la pression sur les conduites restantes à nettoyer en parallèle, si bien que les autres écouvillons atteignent également leur but.
