Definitions

  • the present invention is designed for air compressors driven by a periodically induced water hammer.
  • a water hammer is frequently used in hydraulic rams, water lifting equipments applied to supply water when a water supply exceeds water demand and when the lifting equipment may be installed below the source of water.
  • the efficiency of a hydraulic ram is only from 0.2 to 0.4, its major advantage is an ability to use free water energy.
  • SU 1652674 describes a water hammer driven air compressor having a water feeder with an integrated impact valve and a reservoir divided by a resilient diaphragm into an air and a water compartment.
  • the air compartment has a reverse air intake valve and is hosed via a reversal valve to a pressurized air supply pipe.
  • the water compartment is connected with a water supply pipe.
  • the aforementioned air compressor converts kinetic energy of a water flow into pressurized air energy and allows a more efficient use of potential and kinetic water energy since its operation is based on the use of additional kinetic energy of water obtained in a place of a water level alteration.
  • a deficiency of the compressor is insufficient use of water kinetic energy as only a portion of the constant water flow in the water supply pipe is used to generate energy of pressurized air. The remaining part of the water flow is simply flushed down.
  • RU 2239102 which discloses the closest prior art, describes a water hammer driven air compressor used in hydraulic ram.
  • the compressor has two water supply pipes with integrated impact valves connected by a swinging lever and two air reservoirs with water intake valves.
  • One air reservoir is connected via a water outlet valve and a pressurized pipe to a water transfusion compartment.
  • the other air reservoir has a water outlet valve connected via a swinging lever and an air supply pipe to the water transfusion compartment.
  • Pressurized air in the first air reservoir drives water into the water transfusion compartment while air in the other reservoir drives water from the water transfusion compartment to a pressurized water reservoir.
  • This compressor is designed only to lift water and cannot be used as an independent source of pressurized air which can be applied for various purposes. Besides, it is difficult to adjust its optimal operational mode as it is impossible to control an air pressure level and its duration. Water supply is used inefficiently - it is simply let out into surrounding environment.
  • the objective of the invention is to expand the range of application of the water hammer driven air compressor and maximize utilization of kinetic water energy by converting it into pressurized air energy with minimal waste of water.
  • a water hammer driven air compressor having two water intake pipes with impact valves connected to a water reservoir and two air reservoirs each having water intake and outlet valves one of which is connected to an air supply pipe, the air reservoirs have air intake valves, the water outlet valves of its reservoirs and are controlled by the air pressure in the air reservoirs and the second air reservoir is connected to an air supply pipe which may be coupled with an air receiver.
  • the water outlet valves in the air reservoirs are connected via a unit of levers, a pneumatic cylinder and a pneumatic throttle with an air pressure valve.
  • the air reservoirs are connected via water outlet valves to an outlet pipe which can be connected to a hydraulic ram feeding the used water back to the water reservoir.
  • the hydraulic ram has a water supply pipe with an impact valve, an air reservoir with a water intake valve and a water outlet valve connected via a unit of levers, a pneumatic cylinder and a pneumatic throttle with an air pressure valve and a pressure pipe connected to the water reservoir.
  • the described water hammer driven compressor with or without hydraulic ram may comprise only the first level of a compressor unit.
  • One of the water supply pipes of the first and each following level of the compressor unit is connected to the following level of the compressor unit.
  • the water hammer driven air compressor comprises water supply pipes 1 and 2 with a swinging impact valve 3 connected to a supply pipe 4 coupled with a water reservoir 5 and air reservoirs 6 and 7 with water intake 8 and outlet 9 valves and air intake valves 10.
  • the air reservoirs 6 and 7 are connected via air pressure valves 11 and an air supply pipe 12 to an air receiver 13.
  • the water outlet valves 9 are connected via a unit of levers 14, a pneumatic cylinder 15 and a pneumatic throttle 16 to an air pressure valve 17.
  • the impact valve 3 is connected via a pneumatic cylinder 18 to an air pressure valve 19.
  • a drain 20 is installed below the water outlet pipes 9.
  • the air reservoirs 6 and 7 are arranged to each other at the distance "L" which is fixed depending on the speed of the water flow in the water supply pipes 1 and 2.
  • the water hammer driven compressor may be assembled with a hydraulic ram connected to the drain 20.
  • the hydraulic ram has a water supply pipe 21 with a swinging impact valve 22 connected to the drain 20, an air reservoir 23 with a water intake valve 24 and a water outlet valve 25 connected via a unit of levers 26, a pneumatic cylinder 27 and a pneumatic throttle 28 with an air pressure valve 30 and a pressure pipe connected to the water reservoir 5.
  • the described water hammer driven compressor may be used as the first level of a compressor unit.
  • the pipe 31 makes a supply pipe for the following level (absent in the drawing) of the compressor unit.
  • Water hammer driven air compressor operates as follows.
  • the compressed air passes via the pressure valve 17, the pneumatic throttle 16 with a controlled delay into the pneumatic cylinder 15 which via the unit of levers 15 opens the water outlet valve 9 and the water from the reservoir 6 passes to the drain 20.
  • the air passes via the intake valve 10 into the air reservoir 6 and sets it for a subsequent cycle.
  • the water from the feeding pipe 4 flows trough the supply pipe 2 towards the air reservoir 7 until the flow rate achieves the value at which the impact valve 3 immediately turns and closes the pipe 2 inducing a water hammer in it.
  • the water opens the water intake valve 8 of the air reservoir 7 and fills a part of the reservoir 7.
  • the air compressed by water in the air reservoir 7 is driven via the pressure valve 11 and through the air supply pipe 12 to the air receiver 13.
  • the compressed air from the air reservoir 7 passes with a controlled delay via the pressure valve 17, the throttle 16 to the pneumatic cylinder 15 which via the unit of levers 15 opens the water outlet valve 9 and the water from the air reservoir 7 flows into the drain 20.
  • the drain 20 is coupled with a hydraulic ram, on an immediate turn of the impact valve 22 opened by the spring of the pneumatic cylinder 18 of the air reservoir 23, water from the drain 20 functioning now as a feeding pipe flows via the supply pipe 21 towards the air reservoir 23.
  • the pressure of the water flow in the feeding pipe 21 opens the intake valve 24 and the water fills a part of the air reservoir 23 and advances air pressure in it which via the pressure valve 29, the pneumatic throttle 28, the pneumatic cylinder 27 and the unit of levers 26 immediately turns the impact valve 22 and closes water flow into the feeding pipe 21 inducing at the same time a water hammer in it.
  • the compressed air passes via the pressure valve 29, the pneumatic throttle 28 into the pneumatic cylinder 27 which via the unit of levers 26 opens the water outlet valve 26 and the water from the reservoir 23 passes to the drain 20 and flows back to the water reservoir 5.
