Definitions

  • the invention is based on the object to promote the mixtures in chemical, especially catalytic reactions of reacting solids, liquids with the resulting vapors and gases during the reaction.
  • reaction mixtures can not be circulated, which precludes a continuous reaction. It is therefore an object of the invention to circulate such reaction mixtures during the reaction and to use the good mixing in the delivery system for the acceleration of the reaction and thus reduction of the reaction plant. In the foreground is not the achievement of good efficiencies, but the use of the energy loss to heat the pumped liquid up to reaction temperature.
  • the known pump systems are not suitable for promoting the resulting reaction mixtures of gases and vapors on the one hand and solids laden liquids on the other hand.
  • Radial gear pumps react very critically to the gases and vapors produced during the reaction.
  • the vapors forming during the reaction collect in the center of the impeller because of the low density and lead there to cavitation and to the demolition of the promotion.
  • the associated inadequate NPSH values ie the formation of inadmissible cavitation, lead to the destruction of the pump.
  • the necessary negative pressure for sucking in the reaction mixtures is possible only to a small extent in the case of the customary pumps with radial wheels and outside the range which reacting mixtures have in chemical plants.
  • Side channel pumps are self-priming. The possible negative pressure is not sufficient for the reaction mixtures. Because of the narrow gaps, the transported solids clog the channels. The life of known conveyors is low, if it comes to a promotion at all.
  • liquid ring vacuum pump One type of pump that creates large negative pressures in the inlet is the liquid ring vacuum pump. However, it is not suitable and intended for liquid and solid transport. This pump is capable of sucking gases and vapors, but not liquids and solids. It was therefore sought after a way to make this type of pump also for the promotion of liquids and solids and thus solve the inventive task.
  • the object has been achieved in that the liquid ring vacuum pump combined with the properties of a radial pump.
  • a new type of pump was created, which combines the promotion of fluids of the radial pump, the gas promotion of the liquid ring vacuum pump and also allows the promotion of solids by a special design of the channels.
  • this study revealed the working discovery. It is the combination of both systems that allows the gases and vapors produced during the reaction to be separated from the liquid and to easily convey both states of matter.
  • the separation of the gases and vapors is done on the principle of the liquid ring vacuum pump, which separates and promotes this inward by the centrifugal force of the diegelaufaufrades.
  • the delivery of solid and liquid substances on the circumference is done by a control system of the control discs, which transports these substances axially on the circumference and thus more and more solid and liquid materials are nachge felicitt.
  • control discs On both sides of the wheels control discs are arranged, which limit the pump room.
  • Impellers and control discs are arranged eccentrically. As a result, a liquid ring can form during the intake phase or during gas promotion, which lays on the impeller hub at different distances. Gas-filled spaces are formed which increase and decrease due to the eccentricity.
  • the sludge reactor pump is well suited for the co-promotion of gases and vapors.
  • the liquid / vapor mixture is sucked through a suction slot, which is located in the region of the largest distance of the liquid ring from the hub. Because of the different density, the reaction gas accumulates in the hub region and is ejected via a pressure slot, which is located in the region of the smallest distance of the liquid ring from the hub.
  • the liquid is separated from the gas phase and discharged through openings in the form of slots or holes which are located on the housing outer diameter in the region of the highest case pressure or conveyed via a guide in the next stage.
  • openings in the form of slots or holes which are located on the housing outer diameter in the region of the highest case pressure or conveyed via a guide in the next stage.
  • the liquid guide vanes are arranged in front of the outlet openings. The promotion of liquid is possible only with moderate efficiency. The resulting power loss serves to supply energy to the pumped medium.
  • a narrow axial gap between the housing and the impeller as in the liquid ring vacuum pump is not required because the liquid ring according to the invention does not have to be stabilized in a sealed chamber, but receives axial outlet openings, which are arranged in the region of the highest case pressure, if necessary with downstream guide.
  • the design of the openings enables a comminution of the solids with simultaneous shearing action on the pumped medium.
  • the liquid which flows through the pressure-side outlet openings is deflected in such a way that it is fed to the next stage or used as a bypass in single-stage machines. This results in a better mixing by a longer residence time of the medium and an additional energy input by friction for faster reaction.
  • the ability of the liquid ring vacuum pump is obtained to produce a large intake negative pressure, the gases and vapors as in the vacuum pump in the middle to promote and still the liquid-solid mixture, the mud, while reacting at high radial Temperature with through the pump to promote.
  • the size of the executed in the embodiment of the invention guide profiles and holes thus simultaneously determine the delivery range of the pump to the solid-liquid mixture. Another advantage is the possibility of cleaning the system by reversing the direction of rotation of the pump.
  • the shaft seal used are double-acting, non-directional mechanical seals which are filled with suitable fluid, e.g. Oil can be operated as a barrier medium between the pump side and the atmosphere side seal.
  • the barrier liquid is circulated by means of auxiliary pumps with slight overpressure in relation to the pump-side seal.
  • the pump bearing is arranged between the inner and outer seal so that the barrier liquid is used simultaneously for lubrication and cooling.
  • heat exchangers are connected in the circuit.
  • the higher pressure of the barrier fluid compared to the inner seal prevents the abrasive solid particles, such as metal, glass and stones in the sludge, from being kept away from the sealing gap, bearing and shaft.
  • additional mixing can be achieved in a loop mixer arranged in a bypass tube between the stages (FIG. 9).
  • Figure 1 to 5 shows the cross section through a sludge reactor pump according to the invention.
  • 1 shows the cross section in the front part of the pump, which is connected to the suction port of the pump.
  • the housing is designated.
  • the impeller 2 has a blade ring, which is seen in the direction of rotation, inclined backwards. 3, the shaft is referred to the bearing and the partition 4 to the housing 1 non-positively and positively connected.
  • the outlet opening for emptying the pump is denoted by 5.
  • the liquid ring is connected to the next stage with the mixture inlet for the next stage 6.
  • the ring formed by the centrifugal force on the outer circumference of liquid and solids passes through the intermediate wall between the two stages from outside to inside in the internal mixture inlet 6.
  • the gas, which accumulates in the first chamber inside passes with the gas outlet 7 in the next level.
  • FIG. 3 shows only the part of the intermediate disk which lies at the first stage, the liquid outlet from the first stage being shown as 8.
  • FIG. 5 also shows the gas inlet and gas outlet 6.
  • the result of such a conveyor is shown in FIG 6. It can be seen that although the mud pump has a high negative pressure on the inlet side of the pump, but generates a relatively low discharge pressure. This is very beneficial in chemical reactions with solids because the solids would clog a nozzle on the exit side. At such low output pressures but the additional switching of nozzles is not necessary, since these pressure differences can be controlled by normal, controlled valves without additional throttling with nozzles.
  • Figure 7 shows the embodiment of an inventive slurry reactor pump with 2 reaction chambers. The designations correspond to those of the sectional images.
  • Figure 8 shows the incorporation of such a mud reactor pump driven by an electric motor as a whole aggregate. With 12 while the mud reactor is designated. With 13 of the engine is referred to, which is designed as an electric motor or combustion engine or combustion turbine.

  • 15 of the reservoir for the storage volume of the bearing lubrication is called.
  • 16 the pump for the cooling and lubrication circuit of the bearing lubrication is called. Since the task of the sludge reactor pump is the mixing and heating of the sucked materials, a loop reactor is switched on in the suction and pressure line for further mixing, which further increases this effect. This is shown in FIG.
  • a slurry reactor pump is coupled to an electric motor.
  • the unit has an electrical power consumption of a maximum of 200 kW and an average of 120 kW.
