Definitions

  • the invention relates to cleanable filament modules and a method for their preparation.
  • Sterilization or microbial reduction in liquid media is an important step in many processes. Contamination with active, ie replicable, biological material such as microorganisms or viruses often poses a threat to product safety, which must be effectively counteracted. In addition, there are applications in which the contaminants themselves represent the product and their inactivation represents a desired product modification. Such products include, for example, certain vaccines.
  • the germ reduction by inactivation with ultraviolet radiation, especially with UV-C radiation and especially at 254 nra has been known for a long time and is widely used in practice.
  • Examples include surface disinfection as well as the treatment of liquid media such as drinking and wastewater.
  • a significant technical challenge is given if, in addition to the germs to be inactivated, there are also valuable substances which can to a certain extent also be damaged by the radiation. Such requirements are typical for the sterilization in the field of food and pharmaceutical agents, such as proteins. Additional difficulties arise when the turbidity of the processed liquid in the range of UV-C radiation is high and thus the penetration depth of the inactivating radiation is low. Such applications call for technical systems which, despite the high turbidity, can achieve homogeneous irradiation, that is to say a narrow dose distribution. In the case of appliances flowing through, a certain residence time, equivalent to irradiation time, is additionally to be provided here. The system-specific residence time distribution also leads to a broad, that is to say inhomogeneous, dose distribution in the liquid.
  • the cleaning can be achieved by flowing through the entire apparatus with a cleaning fluid or by mechanical or chemical cleaning of the parts after disassembly.
  • the solutions with internals have by this in addition an increased tendency to fouling and are therefore inferior from the cleanability of the helical tube modules according to the prior art.
  • the helical tube modules in which all components are connected as positively as possible in order to enable optimum flow, disassembly and reassembly of the parts is not possible.
  • the prior art therefore, only a cleaning by flow through with a cleaning liquid is possible. This is naturally not possible during but only after processing.
  • the purely dry cleaning has a significantly lower effectiveness compared to the mechanical or chemical-mechanical cleaning, especially in the formation of deposits on the module walls.
  • chemical detergents themselves are usually detrimental to subsequent applications. This leads to a module having to be cleaned of the cleaning agent after cleaning, for example by rinsing with water.
  • the object of the present invention was therefore to develop an irradiation module for the irradiation of fluids which does not have the abovementioned disadvantages.
  • the invention therefore relates to a cleanable helix module (irradiation module) for the irradiation of fluids comprising a UV-transparent cladding tube (2 or 2a), a radiation source (3) and an externally mounted reactor housing (1 or Ia), so that a wendelför - Miger channel arises, characterized in that the components are mutually movable and a method for its preparation.
  • a helical module is generally characterized in that a helically shaped component is applied in a form-fitting manner via an inner tube (2 or 2a).
  • a radiation source (3) Within the tube (2 or 2a) is a radiation source (3) and between tube (2 or 2a) and helix (1 or Ia) forms a helical channel, which forces a fluid flowing through in a helical flow and thus in laminar Flows generated by secondary vortex cross-mixing.
  • the material of the tube, through which the irradiation of the liquid takes place, should be largely radiolucent. Suitable materials include glass or plastics. The material that forms the channel and is not irradiated should be dimensionally stable in particular. Suitable materials are, for example, metallic materials, plastics, ceramics, glass or composite materials. Should this material be at least largely transparent, complementary or alternative irradiation may also be effected by this component.
  • all wetted parts are made of materials or coatings that are food safe.
  • all media-contacting materials are manufactured from materials or coatings which are known to the person skilled in the art and inert to the medium.
  • reactor housing materials are preferably used, which are so flexible even after shaping that a pressing by mechanical, hydrostatic or pneumatic forces is possible.
  • the module according to the invention is characterized in that there is a relative movement of the individual components, in particular of the tube (2 or 2a) and the helix (1 or Ia), preferably by an inner rotor 8c connected to the sheath (2 or 2a), through and so a mechanical in-situ cleaning takes place.
  • the contacting helical surface can be provided with a seal.
  • Quartz glass tube Tubes made of radiation-transparent or partially transparent plastics can be used. Due to the inventive design of the seal, a scratching of the surface can be prevented in a relative movement. Such scratching would destroy the important optical properties.
  • the processed fluid itself can also act as a lubricant, without the irradiation is thereby prevented. Between quartz glass and
  • Seal forms in this case, a thin film, which ensures sufficient irradiation. Removed contaminants and deposits are discharged through the rotating helical seal from the module. The relative mobility through the Lubricated seal also allows the coil to be pulled off the pipe and separate cleaning of both components.
  • the helix in particular the sealing surface of the helix, is variably constructed in diameter. This allows the seal to be actively pressed against the tube. This can be done for example by a pressure gradient.
  • the seal By applying a higher pressure on the outside of the coil than on the inside, the seal is pressed onto the tube.
  • the pressure can also be applied by the fluid to be processed itself, which is passed before entering the gap between helix (1 or Ia) and tube (2 or 2a), on the outside of the helix, which is the pressure side.
  • a diaphragm can be provided before entering the gap, which increases the pressure loss.
  • Differences in the hydrodynamics in the outer and inner regions can additionally generate hydrodynamic pressure forces, which exert a force on the seal.
  • a stretchability is possible by using stretchable polymer materials of the inner tube (2 or 2a). By applying a hydraulic or mechanical force, the inner tube (2 or 2a) can be pressed against the helix (1 or Ia).
  • the inside of the reactor housing is preferably electrochemically polished to reflect incident rays as best as possible in the medium.
  • an additional irradiation chamber for the fluid is formed on the outside of the helix (1 or Ia).
  • the pressure-side feeder can also be irradiated.
  • the pressure-side feed itself can be embodied in a transparent material, with which an additional irradiation from the outside is possible. In this way, the irradiation intensity is increased.
  • the inside of the helix can be designed to be radiation-reflecting, so that potentially outward radiation is reflected back into the fluid. This may be by using reflective metallic or polymeric materials or reflective coatings of appropriate material.
  • the radiation reflection on the rear wall can increase the light yield in the fluid up to a factor of two.
  • the jacket of the reactor housing (1 or Ia) is produced by a hydroforming process in one operation. Connecting parts, bottom termination and flow control geometries are the preferably without additional materials in a device with a laser welding pressure-tight manner connected to the jacket.
  • the sealing surface of the reactor which faces the cladding tube, is preferably provided with a PTFE coating. As a result, a low friction coefficient is generated, which allows for easy manual removal of the cladding tube and for low energy consumption for the rotary / Hubbe- movement.
  • the sealing of the reactor housing relative to the cladding tube or to the atmosphere is preferably achieved at the head ends by means of food-grade seals (frequently integrated into the flanges) known to the person skilled in the art.
  • the reactor housing can be lapped by a cooling fluid.
  • the process medium and the reactor housing can be kept within a permissible temperature range during the irradiation process. Absorbed radiation components in the process medium and housing are dissipated as heat energy by the cooling fluid.
  • (Ia) and helix (2a) can be interlocked by this shaping and sealed by the application of an inwardly directed axial force which pushes the parts further into one another.
  • An outward axial force allows easy separation of components for cleaning.
  • a locking of the two parts may be provided for the assembled state, so that no continuous force application is necessary.
  • the helix module for easy disassembly and cleaning of only three items is constructed, namely the reactor housing (1 or Ia), the UV transparent cladding tube (2 or 2a), and the UV radiator unit (3). These components can be dismantled by clamping / screw connections in a short time and cleaned by simple means mechanically or wet-chemically.
  • An additional possibility of cleaning is the physical introduction of a pig or a helical insert driven through the channel. This can be done mechanically, by
  • the introduction of the necessary forces for disassembly or relative movement can be done manually as well as non-manually. Not manual options are the force with a motor, preferably an electromagnetic motor, or a hydraulic or pneumatic or non-contact electromagnetic drive.
  • the movement can take place both continuously in one direction and alternately in opposite directions.
  • Such a helical module is used for pharmaceuticals, biological products, antibodies, proteins, enzymes, vaccines, extracts, feeds, foods (for example milk and milk products, juices, syrups, drinks), drinking or wastewater, small or fine chemicals, photobioreactors. Goals include the inactivation of germs, photosynthesis or photochemical reactions.

  • the phage titer was more than 10 7 phage / mL.
  • the solution was recirculated at a flow rate of 10 L / h through a helical module with 24 mL
  • the module consisted of a quartz glass tube over which a Teflon helix hose was positively drawn. Between quartz glass tube and Teflon tube is formed in this way a helical channel through which the liquid can be passed.
  • the quartz glass tube was fitted with a 9W low-pressure mercury lamp, which irradiated the solution through the quartz glass with 35 W / m 2 at the wavelength of 254 nm.
  • the helix module was subjected to an optical control, whereby a significant deposit formation of the liquid-side quartz glass surface could be observed (compare Figure 8).
  • the attempt to clean the surface by rinsing with liquids such as water, soapy water, glass cleaner or NaOH was unsuccessful.
  • the helix module could not be dismantled non-destructively and thus the
  • the cleaned module could be reused successfully.
