Definitions

  • the invention relates to an apparatus and a method for feeding processing plants, in particular incinerators, in which a flowable processing material, which in addition to liquid fractions also solid fractions, is introduced pressurized in the processing plant via a feed line.
  • the invention is therefore based on the object to provide a method and an apparatus of the type described, which is characterized by long service life in a pressurized charge of incinerators with processed material having solid and liquid components.
  • the invention solves the stated problem with regard to the method in that the material to be processed is mixed before it is pressurized.
  • the processing material is mixed before being pressurized, it can surprisingly be ensured, in contrast to the prior art, that the risk of blockage of the delivery line remains low.
  • solid portions tend not or only slightly tend to segregate during production, which has proved to be crucial for the occurrence of blockages.
  • a blockage of the delivery line at long feed operation are not feared, which inventively long service life, especially when running as incinerator processing plants allows.
  • the material to be processed is finally pressurized by a delivery line designed as a lance, which lance is particularly susceptible to clogging. According to the invention, the risk of blockages can also be reduced here.
  • the delivery line is at least partially emptied when the feed of the processing plant is interrupted, it can be avoided that the solid portions of the processed material in the delivery line segregate in such a way that clogging of the delivery line occurs when the charge continues.
  • the object of the invention is achieved in terms of the device in that the preferably in the form of a lance expiring conveyor line is assigned to the pump upstream mixing device, in particular a drum mixer, for mixing the processing material.
  • the conveying line assigned to a mixing device upstream of the pump for mixing the processing material so a clog-free pressure promotion of the processed material can be ensured in a simple manner, since the risk of segregation of the solid components can be kept low.
  • This is particularly advantageous when the delivery line runs out in the form of a lance. Simple construction conditions arise when the mixer is designed as a drum mixer.
  • the delivery line has a screw, it is possible in accordance with the invention not only to convey the material to be processed pressure-free, but it can also be ensured that the material to be processed can be tapped virtually unchanged in its mixing despite conveying. Namely, it is omitted when using a spiral screw a gap-related deposition of liquid fractions and thus a change in the distribution.
  • the delivery line between the pump and the mixer Forms the delivery line between the pump and the mixer from a loop, it can be emptied easily from the processing material in an interruption of the feed the delivery line.
  • the ring line can be connected to a pump arranged in the region of the processing plant in order to ensure pressurized introduction of the material to be processed into the processing plant.
  • the delivery line running between the pump and the processing plant has a connection for additional admixing of liquid and / or gaseous processing substances, then this part of the delivery line can be emptied independently of the pump delivery rate.
  • Fig. 1 a simplified view of the apparatus for feeding a processing plant
  • FIG. 2 shows an enlarged sectional view of the delivery line according to FIG. 1 and
  • FIG. 3 shows an enlarged partial view of the device according to FIG. 1.
  • the device shown in FIG. 1, for example, for charging a processing plant designed as a combustion furnace 1 has a delivery line 2, with which a flowable processing material 3 is deposited. taken and introduced into the combustion furnace 1.
  • the conveying line 2 takes the processed material 3 a mixer designed as a drum mixer 4, which ensures that the conveying line 2 is always a processing material 3 is available, in which the liquid portions 5 and solid portions 6 are mixed, especially in the liquid portions 5, the solid portions 6 are approximately evenly distributed, which can be taken in particular of FIG. 2.
  • Such flowable processing material 3 may represent, for example, oil or oil sludge mixed with plastics, metals and / or silicates.
  • the delivery line 2 formed in this part as a spiral conveyor screw 7 can be seen for pressure-free delivery of the material 3 to be processed.
  • the screw 7 instead of the screw 7 to promote the processing material 3 to use a pumped delivery line 3, which has not been shown for clarity.
  • a spiral screw conveyor has the advantage over other conveyor types that a separation of the processing material 3 during conveying is reduced since the screw elements 8 of the spiral conveyor fly 7 abut almost positively on the outer jacket 9 and thus the liquid portions 5 can not separate from the delivered volume fraction.
  • a pump 10 arranged in the region of the incinerator 1
  • the pump brings the processing material 3 pressurized in the combustion furnace 1 via the delivery line 2 designed as a lance 11 in this part.
  • a screw pump can serve as the pump 10.
  • the material to be processed 3 is conveyed back into the drum mixer 4 with the aid of the delivery line 2, which is designed as a loop between the drum mixer 4 and the pump 10, and the delivery line 2 is emptied, at least in this area.
  • the conveying line 2 protrudes through the filling opening 12 into the drum mixer 4, wherein the spiral screw conveyors 7 of the drum mixer 4 protrude through the filling opening 12 of the drum mixer 4 Delivery line 2 are each driven by a motor 13.
  • the lance 11 or the delivery line 2 running between the pump and the processing plant has a connection 14 with a closing valve 15 for the additional admixing of liquid and / or gaseous processing substances, which can be better seen in FIG. This can be carried out in the case of blockages of the tapered lance 11 a cleaning this.
