[0269]
[0270] The reactor facility 1 is subdivided along the center plane 5 into an upper part 3 and a lower part 4 of the housing; the inner walls, in contact with fluid, of the housing 3, 4 form a heart-shaped rotationally symmetrical reaction chamber 15, 16 which in the fluid-carrying part is electrically conductive and which likewise has an upper part 15 and a lower part 16. The longitudinal axis 2 is equivalent to the rotary axis of the rotationally symmetrical reaction chamber 15, 16. There is also an outlet pipe 7 in the reactor facility 1.
[0271] The fluid medium is introduced into the upper part of the reaction chamber 15 via an inlet pipe 33 through an opening 34 in the housing through a delivery opening 6, which is located at a tangent to the jacket face of the reaction chamber 15, 16, and the fluid medium, dictated by the shape of the reaction chamber 15, 16, assumes an inclined flow direction toward the lower boundary 18 of the floor region 17 of the lower part of the reaction chamber 16. The fluid-carrying walls of the reaction chamber 15, 16 are designed in terms of geometry and the surface such that they produce little frictional resistance and have a low coefficient of friction.
[0272] The fluid medium is set into rotation in the upper part of the reaction chamber 15 and forms a fluid eddy, which is steered in the flow direction along the longitudinal axis 2 to the lower part of the reaction chamber 16. The latter extends from the center plane 5 to a curved floor region 17 with the lower boundary 18 of the floor region. In the lower part of the housing 4, a geometrically ascendingly shaped fluid passage 12 is located, the longitudinal axis of which coincides with the longitudinal axis 2 of the reaction chamber 15, 16. The fluid passage has an eversion 13 with a through bore, which protrudes into the point having the smallest free cross section of the inner walls of the outlet pipe 7. Through the through bore, additional fluid media can be aspirated as needed into the floor region 17 of the lower part of the reaction chamber 16. The point having the smallest free cross section of the inner walls, in contact with fluid, of the outlet pipe 7 is designed as a nozzle 14 for attaining the Venturi effect.
[0273] The outlet pipe 7 acts as the first electrode and has a fluid-tight electrical insulation 20 as well as a first electrical connection 22. The fluid passage 12 acts as the second electrode has a fluid-tight electrical insulation 21 as well as a second electrical connection 23. Both electrodes are connected to a regulating or control unit and a power unit (not shown in the drawings). A direct voltage is applied to the electrical connections 22, 23 of the first and second electrodes and has either a positive polarization (+) at the first electrode and a negative polarization () at the second electrode, or a negative polarization () at the first electrode and a positive polarization (+) at the second electrode.
[0274] The rotating fluid eddy is diverted at the fluid passage 12 while maintaining its speed and enters through the outlet pipe 7 through the inlet opening 8 of the outlet pipe 7. The inlet opening 8 is located in the lower part of the reaction chamber 16 and is spaced apart by a variable spacing a 19 from the lower boundary 18 of the curved floor region 17 of the lower part of the reaction chamber 16. The outlet pipe also has a radius r.sub.2 10 from the longitudinal axis 2 to the outer wall of the outlet pipe 7 as well as a wall thickness d 11. The fluid medium is directed through the outlet opening 9 of the outlet pipe 7 and out of the reactor facility 1.
[0275]
[0276] The fluid medium is introduced into the upper part of the reaction chamber 15 via an inlet pipe 33 through an opening in the housing 34 through a delivery opening 6, which is located at a tangent to the jacket face of the reaction chamber 15, 16, and dictated by the shape of the reaction chamber 15, 16, the fluid medium assumes an inclined flow direction to the lower boundary 18 of the floor region 17 of the lower part of the reaction chamber 16.
[0277] The outlet pipe 7 acts as the first electrode and has a fluid-tight electrical insulation 20 as well as a first electrical connection 22. The lower part of the housing 4 acts as the second electrode and has a second electrical connection 23. Both electrodes are connected to a regulating or control unit and a power unit (not shown in the drawings). An alternating voltage (AC) and/or a direct voltage (DC), each with a positive or negative polarization, is applied to the electrical connections 22, 23 of the first and second electrodes.
[0278]
[0279] However, the outlet pipe 7 does not have any smallest free section of the inner walls and thus no nozzle 14 for attaining the Venturi effect. Instead, the opposed inner walls, in contact with fluid, of the outlet pipe 7 form a constant spacing from one another, as a result of which the outlet pipe 7 in the interior acts as a hollow pipe, which adjoins the inlet opening 8 and has the same free cross section.
[0280]
[0281] Analogously to
[0282] The outlet pipe 7 acts as the first electrode and has a fluid-tight electrical insulation 20 as well as a first electrical connection 22. The fluid passage 12 acts as the second electrode and has a second electrical connection 23. Both electrodes are connected to a regulating or control unit and a power unit (not shown in the drawings). An alternating voltage (AC) and/or a direct voltage (DC) is applied to the electrical connections 22, 23 of the first and second electrodes.
[0283]
[0284] This time, however, the fluid medium is introduced via two openings in the housing 34, two inlet pipes 33 and two delivery openings 6, which are located at a tangent in the cross section to the jacket face of the reaction chamber 15, 16, into the upper part of the reaction chamber 15. The medium here assumes a flow direction inclined to the lower boundary 18 of the floor region 17 of the lower part of the reaction chamber 16 because of the shape of the reaction chamber 15, 16.
[0285] The outlet pipe 7 acts as the first electrode and has a fluid-tight electrical insulation 20 as well as a first electrical connection 22. The fluid passage 12 acts as the second electrode has a fluid-tight electrical insulation 21 as well as a second electrical connection 23. Both electrodes are connected to a regulating or control unit and a power unit (not shown in the drawings). A direct voltage is applied to the electrical connections 22, 23 of the first and second electrodes and has either a positive polarization (+) at the first electrode and a negative polarization () at the second electrode, or a negative polarization () at the first electrode and a positive polarization (+) at the second electrode.
[0286]
[0287]
[0288] The fluid medium is introduced into the upper part of the reaction chamber 15 through a delivery opening (not shown in the longitudinal section), which is located at a tangent in the cross section to the jacket face of the upper part of the reaction chamber 15. A fluid inlet region 45 adjoins the delivery opening (not shown in the longitudinal section) in the flow direction, which fluid inlet region in longitudinal section to the reactor facility 1 on the longitudinal sectional edge has a circular surface with a diameter d.sub.z 35 and an associated center point 46. The center plane 5 extends through the center point 46 of the fluid inlet region 45. The spacing b 40 between the top face 37 and the bottom face 38 is constant. The setting angle 42 refers to the angle which, viewed in longitudinal section in the installed state, is established from the center plane 5, which extends through the center point 46 of the fluid inlet region 45, to the longitudinal axis 2. The setting angle 42 when =90 refers to the angle, established in the installed state, below the center plane 5, that is, from the center plane 5 to the longitudinal axis 2 of the reaction chamber 15, 16. For that purpose, the section of the longitudinal axis 2 with the center plane 5 represents a Cartesian coordinate system. The setting angle 42=90 thus refers always to the third and fourth quadrants of the Cartesian coordinate system. At the setting angle 42=90, the spacing b 40 is equal to the diameter dz 35 of the fluid inlet region 45 and is thus equivalent to the height of the upper part of the reaction chamber 15. The spacing from the transition region 39 from the top face to the bottom face in the upper part of the reaction chamber 15 and the outer wall of the outlet pipe 7 is equivalent to the maximum spacing r.sub.max 36 of the upper part of the reaction chamber 15. The fluid-carrying walls of the reaction chamber 15, 16 are designed such that in terms of their geometry and surface, they generate a slight frictional resistance and coefficient of friction.
[0289] The fluid medium is set to rotation in the upper part of the reaction chamber 15 and forms a fluid eddy, which is steered in the flow direction along the longitudinal axis 2 into the lower part of the reaction chamber 16. The lower part of the reaction chamber 16, from the transition 39 from the bottom face, extends to a curved floor region 17 with the lower boundary 18 of the floor region. The radius r.sub.3 43 is equivalent to the spacing from the transition 41 of the bottom face of the lower part 18 of the reaction chamber to the outer wall of the outlet pipe 7. Furthermore, z 44 is equivalent to the spacing of the lower part of the reaction chamber 16, from the point where the top face 37 and the bottom face 38 of the upper part of the reaction chamber 15 no longer have a constant spacing b 40 from one another. Here, z 44 extends to the lower boundary 18 of the floor region 17 of the lower part of the reaction chamber 16.
[0290] A geometrically ascendingly shaped fluid passage 12 is located in the lower part of the housing 4, and its longitudinal axis coincides with the longitudinal axis 2 of the reaction chamber 15, 16. The fluid passage has an eversion 13 with a through bore, which protrudes into the location having the smallest free cross section of the inner walls of the outlet pipe 7. Through the through bore, additional fluid media can be aspirated as needed into the floor region 17 of the lower part of the reaction chamber 16. The location with the smallest free cross section of the inner walls, in contact with fluid, of the outlet pipe 7 is designed as a nozzle 14 for attaining the Venturi effect. The rotating fluid eddy is diverted, while maintaining its speed, at the fluid passage 12 and enters through the inlet opening 8 into the outlet pipe 7. The inlet opening 8 is located in the lower part of the reaction chamber 16 and is spaced apart at a variable spacing a 19 from the lower boundary 18 of the curved floor region 17 of the lower part of the reaction chamber 16. Furthermore, the outlet pipe has a radius r.sub.2 10 from the longitudinal axis 2 to the outer wall of the outlet pipe 7 and also has a wall thickness d 11. The fluid medium is carried out of the reactor facility 1 through the outlet opening 9 of the outlet pipe 7.
[0291] The fluid-carrying walls of the reaction chamber 15, 16 are designed such that in terms of their geometry and the surface area, they produce a low frictional resistance and coefficient of friction. Because of the lesser friction of the fluid medium in the reaction chamber 15, 16 of the invention, the requisite pressure for generating the fluid eddy and for attaining the Venturi effect in the nozzle 14, with a superimposed negative pressure of 0.99 bar, is 3.5 bar, which is approximately 42% lower compared to EP 1 294 474, which for the same reaction chamber volume requires a pressure of 6.0 bar.
[0292] The outlet pipe 7 acts as the first electrode and has a fluid-tight electrical insulation 20 as well as a first electrical connection 22. The fluid passage 12 acts as the second electrode and has a fluid-tight electrical insulation 21 as well as a second electrical connection 23. Both electrodes are connected to a regulating or control unit and to a power unit (not shown in the drawing). A direct voltage and/or alternating voltage is applied to the electrical connections 22, 23 of the first and second electrodes.
[0293]
[0294]
[0295] Exemplary Embodiment of Slaughterhouse Waste Water Treatment:
[0296] The device of the invention can be employed for instance in the rinsing and waste waters that occur in slaughterhouses or large-scale slaughtering operations. Because of the high proportion of blood, the water has a high protein content. With the device and the method of the invention, the BOD and COD values can be improved drastically and in a short time in the electrolysis of the slaughterhouse waste waters.
[0297] The slaughterhouse waste waters are treated on the one hand purely flow-dynamically, without adding air, through the through bore of the fluid passage, and also with an additional electrolysis with the addition of air through the through bore of the fluid passage.
[0298] In the purely flow-dynamics treatment, a COD value of 4300 mg/l and a BOD value of 2070 mg/l can be measured; conversely, in the additional electrolysis with the delivery of air, a COD value of 3300 mg/l and a BOD value of 1790 mg/l can be measured. Further measurements for the purely flow-dynamics treatment of the slaughterhouse waste water produce a COD value of 2800 mg/l and a BOD value of 1250 mg/l. Conversely, in the additional electrolysis with the delivery of air, a COD value of 1600 mg/l and a BOD value of 670 mg/l can be measured. It can therefore be seen unequivocally that COD and BOD values, by means of an additional electrolytic treatment of the slaughterhouse water, are markedly lower than with a purely flow-dynamics treatment.
