Definitions

  • Equipment for cutting a pitch rope into pitch granules or likes comprising some pitch rope flow stream guiding means
  • the present invention relates to a cutting equipment for cutting a pitch intended to be immerged.
  • the invention relates to an equipment for cutting a pitch rope into pitch granules or likes when the equipment is immerged into a cooling fluid basin.
  • the equipment according to the invention is adapted for producing shape controlled granules of solid pitch.
  • the pitch is a carboneous product obtained as after processing of various heavy hydrocarbons recovered form coal tar processing, reformer decantation oils, crude oil distillation, biomass pyrolytic oil residues and other sources.
  • the pitch is conditioned under different forms according to the end-user specifications and needs.
  • a common form is as solid granules or pellets.
  • the cutting means is composed of items taken from: a cutter, a counter-cutter, a cutting-means enclosure.
  • the cutter can be mobile or static; it can bear various shapes and number of cutting blades.
  • the counter-cutter may be optional and can be mobile or static.
  • a cutting-means enclosure is used to protect the operator; it can be optional according to the design of the granulation equipment. According to the cases, the enclosure can also fulfill the roles of feed hopper or granulated product outlet duct, even if it is not its primary role.
  • the granulation of pitch, or pitch related products such as carbon black or solid carboneous fuels, can be obtained with various types of granulators.
  • a first type consists in a vertical pitch extruder that forms pitch rope :»s (US3.334.167). Extrusion is operated underwater. The pitch ropes flow into a pool filled with water until it reaches the bottom of the cooling pool. At the bottom of the cooling pool it is broken into pitch rods of variable lengths by a screw conveyor.
  • a second type of granulator is designed from a perforated plate (US4.107.382).
  • the pitch flows by gravity through the perforations and forms droplets that fall into a water drum resulting in the formation of pitch pricks.
  • a third type of granulator is composed of a conveying belt on which the pitch is spread as an irregular layer (US3.836.354).
  • a series of fixed cutters allows forming strings that are then re-cut into irregular brick like pitch solid with guillotines.
  • a fourth type of granulator is based on a continuous extrusion of pitch between two embossed rotary molds resulting into the formation of pitch tablets (US5.236.468).
  • Pitch tablets can also be formed with a rotoforming machine (US7.344.368): the liquid pitch is fed hi a rotary drum fitted with perforations leading to the deposition of small amounts of pitch on a conveying belt. These small amounts have to be cooled down to form the desired solid pitch tablets.
  • a last granulator is composed of a rotary cutter with a rotary counter-cutter (US4.482.517). Both cutter and counter-cutter are cylinders and are located underwater. The immersion depth is variable. The cutter bears longitudinal cutting blades. The cutter and counter-cutter turn in opposite direction. The speed of the counter cutter can be slightly different of the speed of the cutter. The cutter may have an internal circulation of water which main purpose is to cool down the cutter. Some holes on the body of the cutting cylinder can be used to evacuate this cooling water at specified locations. The resulting solid pitch forms elongated cylindrical granules with crushed ends.
  • the granulation system includes, in general, a fast cooling of the liquid pitch through a quench.
  • Some of the previous systems were designed to include such a quench.
  • the quenched and the solid pitches form some glass like material that may break during cutting and form some fine glass like powders. It is in general advised to collect these fines and avoid their dissemination.
  • the previous systems were designed to fulfill some of the requirements of quench and limited or no dispersion of fines thanks to recovery of pitch solids in a basin filled with a cooling fluid such as water.
  • the requirement of a controlled shape factor for the solid pitch granules tends to favor the use of granulation systems that allow reaching such a specification.
  • the rotoformer, the embossed rotary molds and the rotary cutter and counter-cutters are therefore preferred equipments for such an aim.
  • the rotoformer leads to the production of small calibrated pitch tablets that present some drawbacks such as an important friability.
  • the rotary molds can be plugged by thick and sticky pitch; additionally they do not allow a satisfying quench of the processed pitch by themselves.
  • An equipment of choice is therefore the combination of immerged cutter and counter- cutter.
  • the entrained pitch forms a shell around the cutter and counter-cutter.
  • the cylinders are not blocked but become unreachable by the pitch fed in the granulator and the equipment must be stopped for maintenance and cleaning.
  • the invention provides an item of equipment for extrusion of pitch in the shape of a rope, which goes into water and is cut into segments of the desired and adjustable length by a suitable set of cutter and counter-cutter.
