Definitions

  • the invention relates to a method and a device for the purification of gases and liquids and / or for the recovery of particles or dissolved substances contained therein or for carrying out other process engineering processes.
  • a gaseous or liquid medium normally goes through a number of process stages in which various chemical and / or physical reactions take place or take place until a desired state of the medium is reached. This applies to production processes as well as to processes for wastewater or exhaust air treatment or their treatment (e.g. drinking water) and for the circulation of various substances.
  • ion exchange systems which are built up from numerous containers and connected to one another by means of pipelines are known. These ion exchange containers have the disadvantage, among other things, that the individual containers cannot be used up to their full capacity because the ion exchange resin used to secure them against Ion breakthrough must remain partially uncharged.
  • DE-PS 2 602 232 a device for recovering metals in rinsing water from electroplating systems with at least two series-connected transportable ion exchanger containers and an upstream filter is known, in which the flow from bottom to top, covered at the top and bottom with a sieve and Provided at the edges with circumferential seals, also ion exchanger containers filled with ion exchange resin are arranged vertically one above the other.
  • a disadvantage of the procedural process stages e.g. mixing, separating, precipitating, separating, etc.
  • the devices used for this purpose is that the process stages required for this can be carried out in separate, fixed systems which are specifically designed for this purpose. This means that this involves a relatively high outlay on equipment technology, the space and operation required.
  • the advantage of the invention is that due to the modular structure of the individual filled and different from each other and the same substances a device unit or reaction column combined container, an extremely compact design is achieved for the process control and the system can be easily adapted to changing flow rates or tasks.
  • a service system in which the regeneration or reactivation of the individual modules takes place centrally, as is known, for example, for ion exchange technology in electroplating, there are applications for the individual modules forming a system which have hitherto been used for some of the known ones Process stages were at least partially closed.
  • the process stages are e.g. filtering, ion exchange, electrochemical processes, mixing, catalytic processes, separation, enrichment, regeneration, precipitation, separation.
  • the preferred active substances or assemblies are ion exchange resins, adsorber resins, activated carbon, diatomaceous earth, aluminum oxide, burnt lime, granulated peat, and molecular sieves, mechanical filters, membranes, electrolytic cells, catalysts, etc. for use.
  • the individual modules are arranged one above the other in the subject matter of the invention similar to the known devices, they differ essentially from the fact that a method is used here in which the containers are filled with different active substances or assemblies and / or where the flow is not only in a single flow in one direction from bottom to top or vice versa and from one module in the other, i.e. from the bottom to the cover, but also within the individual modules of several flows in or from different directions.
  • individual modules are provided with side connections and / or a central passage (e.g. pipe) to act on adjacent modules.
  • a partial flow flows through one or two first reaction modules in order to then flow together with the other partial flow as a mixture through further reaction modules connected downstream.
  • a module can be designed as a high-pressure component and the modules connected downstream of it as low-pressure components.
  • the R can e disordersmodule be embodied in different lengths from each other, and construction methods.
  • the overall length or height of the individual containers or modules is an integer multiple or part of their standard height or length, in order to ensure an exchange or a possibility for their free combination with one another.
  • the flows are conveyed either via a free gradient or externally arranged pumps.
  • the lower one is designed, for example, as an electrolysis module or cell 1 ', on which the ones with, for example, an ion exchange resin Yes (see module 2 in section) coated containers or modules 2, 3, 4 are arranged one above the other.
  • the electrolysis module 1 "formed with the outer wall 8 and a fixedly connected thereto and provided with a central bore 9 bottom 10th from the top of the electrolysis module 1 'or K is athodenwanne 1" as the cathode pan 1 of one, also having a central bore 11 provided and against the cathode pan 1 "electrically insulated e is lid 12 covered.
  • bottom 10 and cover 12 and the bores 9 and 11 connects a 'arranged centrally in the electrolysis module 1 through the flow tube 13.
  • anode rods 14, 15 which in protrude the cathode tub 1 ".
  • the containers or modules 1, 2, 3, 4 are provided at their ends with filter elements 16 known per se (for example sieves, membranes, diaphragms and the like).
  • the individual containers or modules 1 ', 2', 3 ', 4' are provided with seals 22 on their connecting surfaces (cover bottom) in order to avoid leakage losses of the media to be treated.
  • the arrangement of the individual containers or modules 1 ', 2', 3 ', 4' can of course be combined. This means that the partial flows can flow through different combinations.
  • module 1 as an electrolytic cell 1 '
  • modules 2, 3, 4 as an ion exchanger Yes or module 1' as a mechanical filter
  • reaction modules 1 ', 2', 3 ', 4' have different lengths l, 1 1 , 1 2 , 1 3 and designs for use as reaction columns 7.
  • the lengths l, 11, 1 2 , 1 3 are selected so that, for example, the modules 2 ', 3', 4 'arranged downstream of the module 1' are each half or shorter than the preceding module; So module 2 ', for example, equal to 0.5.
  • Module 1 ', module 3' equal to 0.5.
  • two partial streams X and Y can be mixed with one another (X + Y) in the base trough 5.
  • module 1 ' is an electrolysis cell
  • module 2' is an anion exchanger
  • module 3 ' is a cation exchanger
  • module 4' is another type of filter.
  • the module 1 ' can also be designed in a high-pressure version as a membrane stage and the modules 2', 3 ', 4' in a low-pressure version. In FIG. 2b mixing does not take place since only one media stream is subject to the process control.
  • An in The partial flow 23 flowing into the floor pan 5 is pressed, for example by pumping power 20 ', into the module 1' designed as a candle filter, and further into the line 24 through the modules 2 'and 3', for example filled with activated carbon.
  • FIG. 3 shows a device for treating two separate media or material flows X and Y.
  • the flowing into the floor pan 5 and from this by pumping power 20 ' flows into the through the e.g. Modules 1 'and 2' designed as electrolysis cells 1 'and flow tube 13 leading into the downstream and e.g. Partial stream X pressed as ion exchanger modules 3 'and 4' into line 24.
  • Partial stream Y initially flows into module 2 ', from there via a free slope (see directional arrow) or an external pump (not shown in detail in the figure) shown) in the module 1 'and from there in the line 23.
  • X used developer
  • Y used fixing bath
  • X fresh water flow
  • Y waste water
