Definitions

  • the invention relates to a device for the splitting of hydrocarbon chains used in a thermo-catalytic conversion process in which from biomass and other hydrocarbonaceous materials gaseous or liquid fuels can be obtained.
  • carbonaceous materials By entering into a hot oil cycle, carbonaceous materials can be heated, freed of their water content and then, with the addition of a catalyst, decomposed in a housing by the action of a rotating impeller and split the hydrocarbon chains contained by mechanical action and the effect of the input catalyst.
  • hydrocarbon chains can be broken down and fuel extracted over a limited period of time, whether by an externally electric or flame heated reactor, or by a reactor in which heat is internally generated by mechanical movement of vanes or impellers Energy is registered.
  • Vacuum pumps and other devices constructed according to the basic principle of the liquid ring vacuum pump are suitable for showing in a test setup over a certain period of time that it is possible to carry out this conversion process in this way.
  • a big difference is that process-related moves in this new application of a well-known pumping principle instead of gas or air at room temperature, liquids, solids and abrasive catalysts at temperatures up to 350 ° C.
  • the process fluid mainly consists of oil
  • the entrained solid particles settling in the bearings lead to lubrication faults, but above all lead to the aluminum silicates carried along in the process fluid and necessary for the process.
  • lime used as an acidity regulator by high abrasiveness even with smaller quantities after a short time to severe damage to the shaft bearings.
  • the shaft bearings are now in operation, neither high temperatures, nor abrasive catalysts or acidity regulators, nor contamination exposed to the raw material input, run in a clean environment with proper lubrication and now, together with the high increase in shaft stability by the spaced apart with a double shaft bearing, despite the extension of the non-supported bearing area, a long service life.
  • stuffing box packing seals which must always be adjusted to a certain degree of leakage for proper operation, should not be the first choice for applications in the range above 300 ° C.
  • the packing materials are resistant to temperatures well above 500 ° C, but also heavier oils begin to evaporate from 280 ° C, with the effect that at lower temperatures otherwise tolerable leakage, does not drip outside and can be easily collected, but the Partly evaporated outlet and thereby forms toxic fumes that escape into the environment and even for people who work on such a system are intolerable.
  • the service temperature is not limited by the thermal loading capacity of the sealing slip rings (e.g., silicon carbide above 1000 ° C), but by the secondary seals necessary to compensate for axial shaft expansion.
  • the housing of the device described in the invention also has ever in the shaft passage on holes on which are connected to the outside of the housing lines through which oil in these oil chambers on or deployed, and from the outside oil quality and oil level in the oil chambers can be controlled.
  • the gap between the shaft and the throttle tube of this oil chamber is minimal and there is the same pressure on both sides of the throttle ring, no or only an extremely low fluid flow takes place, even only small particles of solid particles can pass the throttle tube.
  • the oil in these oil chambers can occasionally be checked for possible interference during operation, and replaced if necessary.
  • the required oil can be taken from the quota of purified oil, which, due to the process, is always fed into the process cycle anyway, which means that no additional expenses are incurred.
  • the device described in this invention unlike the conventional design of the two-chamber liquid ring vacuum pumps not on each side of an input and an output, but only one input on one side and an output on the opposite side.
  • the housing shape for the mounted on both sides version ( FIG. 1 ), on both sides in each case two, with a distance from one another positioned shaft bearing, in order to ensure sufficient stability under the strong load of the impeller and the shaft by viscous liquids and solids.
  • a larger diameter shaft is used compared to the double sided bearing version with the same impeller diameter, and the housing is designed so that the shaft bearings are positioned at a distance at least equal to but better than a multiple of the shaft diameter.
  • both inventions described versions of the device both the version with both sides of the impeller mounted shaft ( FIG. 1 ) as well as the version with unilaterally mounted shaft ( FIG. 2 ), can now by the integrated oil chambers with throttle tube protect the seal chamber, be equipped with, designed for industrial applications, virtually leak-free mechanical seals, and have the housing shape with arranged outside the process fluid range shaft bearings over the previously extreme service life by contamination of the shaft bearings ,
  • FIG. 1 shows an embodiment of the device with passing through the housing (2) shaft and on both sides of the housing two each outside the process fluid area arranged shaft bearing (1) and also on both sides of each oil chamber (7) with a throttle tube surrounding the shaft (8) for sealing off the sealing area from the process fluid area.
  • FIG. 2 shows an embodiment of the device with cantilevered shaft having on one side of the housing two, outside the process fluid area arranged shaft bearing (1), and in the sealing region of the oil chamber (7) with a surrounding the shaft throttle tube (8) for sealing the sealing area opposite the process fluid area.
