Definitions

  • the ring canal blower has a housing with a lateral canal in front of one or both front sides of a rotor for compressing gases as well as intake and pressure connection stubs which are connected directly to each other via the canal or canals.
  • the housing has an outlet for hot gas located between the intake and pressure connection stubs as viewed in the direction of rotation of the rotor as well as an inlet for cool gas.
  • the inlet for the cool gas communicates with the hot gas outlet via the rotor compartments that pass by.
  • the outlet and inlet serve to draw off the hot gas disposed within the rotor blade compartments while replenishing these compartments with cool gas.
  • This invention relates to a ring-canal blower for the compression of a gas.
  • the invention provides a ring-canal blower which has a housing, an intake connection stub and a pressure connection stub in one face and a lateral canal connecting the intake connection stub to the pressure connection stub with an outlet in the housing between the pressure connection stub and intake connection stub for expelling hot gas as well as an inlet for cool gas.
  • the outlet is positioned so that the heated gas which is conveyed in the compartments of the rotor is expelled through the outlet while the inlet is positioned so that cool gas can be drawn into the rotor compart ments as the rotor passes by the intake.
  • the outlet for the heated gas is located at the periphery of the blower housing while the inlet for the cool gas is located in the same radial plane as the outlet so as to communicate with the outlet via the rotor compartments.
  • the heated gas can be expelled to the surrounding atmosphere while the cool gas is drawn-in from a cooler part of the surrounding atmosphere.
  • outlet and inlet are connected to a closed recirculating system in which the expelled hot gas is cooled by a suitable means prior to reentry into the blower.
  • FIG. 1 illustrates a top view of an open housing of a ring-canal blower according to the prior art with the rotor removed.
  • FIG. 2 illustrates a view taken on line 22 of FIGS. 1 and 6.
  • FIG. 3 illustrates a view taken on line 3-3 of FIGS.
  • FIG. 4 illustrates a view taken on line 44 of FIGS.
  • FIG. 5 illustrates a view taken on line 5-5 of FIGS.
  • FIG. 6 illustrates a top view of an open housing of a ring-canal blower according to the invention.
  • FIG. 7 illustrates a view taken on line 7-7 of FIG. 6 showing a hot gas outlet and a cool gas inlet according to the invention.
  • FIG. 8 illustrates a schematic view of a closed system utilizing a ring-canal blower according to the invention.
  • a single state ring-canal blower has a housing G of two-part construction which mounts a rotor (not shown) of known construction therein.
  • the housing G includes a central aperture W for passage of the shaft (not shown) of the rotor.
  • Each part of the housing G is provided with an intake connection stub S and a pressure connection stub D on the front face. As shown respectively in FIGS. 3 and 4, the intake connection stubs S and the pressure connection stubs D are disposed on opposite sides of the housing G from each other.
  • a lateral canal K is formed in each housing half and extends from the intake connection stub S to the pressure connection stub D therein so as to freely communicate the intake connection stub S with the pressure connection stub D. As shown in FIG. 6, each lateral canal K extends in the direction of rotation of the rotor (not shown) as indicated by the arrow.
  • compartments Z are located between the blades of the rotor L in facing relation to the intake and pressure connection stubs S, D. Also, as shown in FIG. 2, the compartments Z are located in facing relation to the lateral canals K.
  • the blower housing G is also provided with an outlet A which is located in the periphery of the housing at a suitable inclined angle and between the pressure onnection stub D and the intake connection stub S as viewed in the direction of rotor rotation.
  • an inlet E is provided in each half part of the housing G between the pressure connection stubs D and the intake connection stubs S and in the zone of the lateral canals K.
  • the outlet A and inlets E are positioned relative to each other so as to be in communication with each other when a rotor compartment Z passes by.
  • gas is drawn in through the intake connection stubs S (FIG. 4) and passed into the respective lateral canals K.
  • the gas is conveyed through the canals K and within the compartments Z (FIG. 2) and compressed.
  • the compressed gas in the canals K is expelled (FIG. 5).
  • the compartments Z become aligned with the inlets E and the outlets A (FIG. 7).
  • the hot gas within the aligned rotor compartments Z is expelled under centrifugal force through the inclined outlet A while cool gas from a suitable source is drawn into and fills the compartments Z through the inlets E.
  • the blower in order to avoid mixing air with a pumped gas, or in the case of series-connected stages in multi-stage blowers, the expelling of the hot compressed gas through the outlet an the inlet of cool gas can take place in a closed circuit KR.
  • the blower is constructed in a similar manner to that described in FIGS. 6 and 7 above; however, an outlet A for the hot gas is connected directly to the closed cooling circuit KR at one end while an inlet E for a cool gas is connected directly to the closed cooling circuit KR at an opposite end.
  • the closed circuit KR includes a cooler KU which is exposed to the outside environment in a suitable manner so as to effect a cooling of the hot gas flowing therethrough in a heat exchange manner.
  • a circulation pump U is provided downstream of the cooler KU to assist the basic output of the hot gas via the outlet A which occurs due to centrifugal force.
  • hot gas from the rotor compartments exits via the outlet A and is passed into the closed circuit KR. Thereafter, the hot gas flows through the cooler KU and is cooled to a suitable temperature. The cooled gas thenpasses to the pump U and is pumped back into the blower housing G via the inlet E.
  • a ring-canal blower for the compression of gas comprising a housing having at least one from face;
  • a rotor having rotor compartments open at the sides and periphery of said rotor within said housing; an intake connection stub in said face of said housing communicating with said ring canal;
  • an inlet in said housing positioned radially inwardly of said outlet between said pressure connection stub and said intake connection stub for drawing in cool gas, said inlet and said outlet being in communication with each other via each respective rotor compartment during rotation of said rotor.
  • a ring-canal blower as set forth in claim 1 further comprising a closed cooling circuit connecting said outlet to said inlet for cooling of the hot gas expelled from said outlet and returning the cooled gas to said inlet.
