Definitions

  • the invention relates to a device for increasing the gas pressure of cryogenic, liquefied gases from tank systems.
  • a new field of application for the gas pressure increase of industrial gases is the treatment of sewage sludge from sewage treatment plants.
  • various methods for sludge disintegration are used.
  • the cell walls of the microorganisms contained in the sewage sludge are destroyed, whereby a thickening of the sewage sludge is substantially facilitated.
  • a gas under high pressure eg 10 to 200 bar above atmospheric pressure.
  • the gases used are technical gases such as oxygen, nitrogen or carbon dioxide. These are available in standard fueling systems whose operating pressure is not always sufficient for this process. Therefore, additional pressure booster systems must be provided.
  • conventional pressure booster systems are problematic because the required discontinuous operation, a cold running of the pump is difficult.
  • pressure booster systems are associated with high acquisition costs.
  • the booster systems equipped with pumps or compressors also have sensitive units that require high maintenance and operating costs.
  • the present invention has for its object to provide a gas pressure booster system for supplying gases from tanks for cryogenic liquefied gases available, which largely manages without mechanical compressors or pumps.
  • the tank system is connected via a valve having a feed line with a dosing, which in turn is connected via a valve having a connecting line with an evaporator in connection, wherein the evaporator on the one hand via a valve having a return line from the a bleed line having a valve (5) branches off, is connected to the supply line to the metering container and on the other hand leads away a removal line having a valve from the evaporator.
  • the proposed gas pressure booster thus has neither pumps nor compressors and comes with conventional containers and evaporators.
  • the gas taken from a standard liquefied gas tank can be increased to the desired pressure.
  • the removal line of the evaporator is preferably in communication with at least one gas storage.
  • the gas storage can be designed as a gas container or as a cylinder bundle.
  • the volume ratio of dosing and gas storage can be adjusted.
  • the volume of the dosing and the volume of the gas storage in the ratio 1:10 to 1: 200.
  • the dosing can have a volume of 4 to 10 liters
  • the gas storage consists of several gas storage containers, in particular a gas cylinder bundle with 5 to 12 gas cylinders.
  • the metering container is preferably vacuum-insulated.
  • an air-heated evaporator is used as the evaporator, in which the evaporation takes place by ambient air.
  • the performance of the pressure booster can be increased even more.
  • the invention is suitable for all processes in which gases from standard liquefied gas tank facilities are required at higher pressures than the operating pressures of the tank installations.
  • a particularly interesting application is the disintegration of sewage sludge by the application of gases under high pressures.
  • the figure shows a pressure booster for increasing the gas pressure of oxygen from a liquid oxygen tank system.
  • This pressure booster system is intended for the gas supply of a reactor for the disintegration of sewage sludge.
  • the reactor for the disintegration of sewage sludge is not shown in the figure.
  • a previously relaxed metering 7 is filled via line 6 by pressure with liquid oxygen.
  • the metering container 7 is connected via a line 8 with a consisting of a cold part 9 and a warm part 10 evaporator.
  • a return line 11 leads back to the dosing 7.
  • a vent line 12 is connected to a muffler.
  • the warm part 10 of the evaporator is connected via a line 13 with an existing gas cylinder bundle 14 gas storage in combination.
  • a provided with a pressure reducer 16 gas discharge line 15 finally leads to the reactor, not shown, for the disintegration of sewage sludge.
  • the operation of the gas pressure booster plant is carried out as follows:
  • valves 1 and 5 are closed.
  • the gas is removed via valve 3.
  • the valve 3 When the valve 3 is open, the gas pressure in the oxygen cylinder bundle 14 drops.
  • the valves 2 and 4 are closed.
  • the valve 5 is opened and closed again after about 10 seconds.
  • the valve 1 is opened and the dosing 7 filled with liquid oxygen from the connected tank system, which is operated for example at a tank pressure of about 18 bar.
  • the valve 1 After filling the dosing tank 7, which is achieved, for example, after 30 seconds, the valve 1 is closed again.
  • the valve 4 is opened and the pressure in the dosing tank 7 increases until pressure equalization.
  • Valve 2 is opened so that the liquid oxygen flows into the cold part 9 of the evaporator. In this case, a pressure equalization takes place via valve 4.
  • evaporation of the liquid oxygen increases Pressure in the evaporator 9, 10 or in the oxygen cylinder bundle 14 according to the volume ratio.
  • the predetermined minimum pressure of eg 48 bar the steps described above are repeated.
  • the gas may e.g. used to drive pneumatic valves instead of compressed air.
  • the gas can also be used for other processes with lower gas pressure.
  • oxygen can be used for the additional fumigation of activated sludge plants in sewage treatment plants. A partial relaxation in the tank to build up pressure is possible.
