Definitions

  • the invention relates to a method for gas supply and gas recovery under Use of a gaseous medium, which in at least one stacking container is stored under pressure and from the stack container, if necessary via a Pressure converter, to a consumer (supply) and consumer, optionally via a pressure transducer, to at least one stack container or to another stack container (recovery) is passed.
  • the invention further relates to a device for gas supply and recovery using a gaseous medium comprising at least one stack container for storing the medium under pressure and one or more compounds from the at least one stack container, optionally via a pressure converter to a consumer (supply) and from the consumer, if necessary via a Pressure converter to or to another stack container (recovery).
  • Such methods and devices are used, for example, in the supply of gas a hot isostatic press and used in high-pressure gas quenching. in the The following is the prior art and the invention based on these applications closer look.
  • the gas is mostly in liquid form in a cryogenic storage tank (storage tank) at max. Stored at 18 bar.
  • a pressure booster and a high pressure evaporator the gas is pumped into the one stack container
  • the gas from the buffer tank in which the gas is stored in gaseous form at the required pressure (up to 300 bar) is introduced into the HIP system until pressure equalization of the two systems. Should however, the pressure in the HIP system should be too low, so must via the pressure transducer Gas must be pumped from the buffer tank in the required amount and pressure.
  • the gas is generated by the oven integrated in the HIP system Heated to 1000 ° C, whereby the pressure, for example, increases to 1000 bar.
  • the pressure is released from the HIP system and returning the gas to the buffer tank until pressure equalization of the two Systems. Subsequently, by the pressure converter, the gas, which is still in the HIP plant is pumped into the buffer. Due to the design of the pressure converter There is still residual gas in the HIP system, which is blown off as a loss to the outside becomes.
  • Another example provides high pressure gas quenching.
  • annealed (heated) materials preferably steel, by compressed gases Quenched in a short time in a hardness structure, then in a succession process application-specific remunerated (tempered).
  • tempered application-specific remunerated
  • the present invention is therefore based on the object, a method and a Device of the type mentioned above, which the gas supply and - improve recovery while avoiding the mentioned disadvantages. It should especially the (pressure) energy - depending on the practical task and the local conditions - as optimal as possible for the reduction of gas consumption and the necessary external energy.
  • the invention is based on the fact that so far only one stack container is replaced by two or more stacking containers whose operating pressures are cascaded are.
  • the individual stack container both in their volumes as be adapted to the specific conditions of use in the design.
  • stack container also includes buffer containers detected.
  • a general filling process takes place in that - as in the figure shown - the consumer first from the first container (container 1 has the lowest, container 5 in the figure, the highest operating pressure) up to a set first pressure level measured by a sensor filled.
  • the sensor closes the first container and opens a second container again up to one certain pressure. Then this second container is also closed and the next container opened. This sequence will be until you reach the desired Working pressure continued.
  • the handling is done in reverse order. First, will in the container with the next lower actual pressure (for example, after container 5 in container 4) and then in the reverse order described. After this Relaxing in the first container (container 1) can cause the residual gas in the consumer discarded (e.g., released into the atmosphere)). The residual gas can also over led a cleaning and filtering stage or another use, e.g. one Combustion in a heating system, be supplied.
  • the storage tank (tank) ago Before a new filling and emptying process, the storage tank (tank) ago, possibly via a pressure booster, the stack container again brought their output pressure.
  • the time required for filling gas volume is significantly below the amount of gas to be supplied in the prior art. It can vary depending on Technology and structural design up to 90% gas and up to 95% compression energy be saved.
  • the physical force for gas transport is advantageously the difference of State variables of the medium won.
  • the physical force results for gas transport either from a different pressure and / or different Operating temperature between the containers (also between consumers and stacking container).
  • means for transferring the gas present in a gas Pressure energy on the stack container without mixing this gas with the in the Stacking gas can be provided.
  • the invention can be used such that the pressure of the gas already used via means for (pre-) compressing a stacking container of a (suitable) pressure stage is used (e.g., by means of a corresponding device).
  • these Means are a container arranged in the balloon or a suitable piston translation (pneumatic translation).
  • the stack container in the invention can also cased together Be a bunch of bottles.
  • the LPG storage tank (storage tank) is optionally to a higher pressure, e.g. 36 bar, designed.
  • the HIP system is emptied using the temperature gradient between HIP plant and containers first the last cascade 5 on the filled maximum pressure of the cascade. Subsequently, the other cascades filled up to the maximum pressure or until pressure equalization.
  • the cascades can always through the HIP facility and do not need to be filled by a pressure transducer.
  • the loss amount of gas is from the liquid tank (e.g., 36 bar) by pressure equalization into the first cascade filled. In most cases it is therefore not necessary, after the initial filling of the Cascades to pump gas into the cascades by increasing the pressure.
  • the steel is quenched in a high-pressure gas system, a so-called. Cold chamber instead of the usual oil bath.
  • a high-pressure gas system a so-called. Cold chamber instead of the usual oil bath.
  • the batch (the workpiece) is transported from the annealing furnace to the cold chamber, the cold chamber closed, with gas, in this case with hydrogen (other gases such as He, N 2 , CO 2, etc., or mixtures thereof are also conceivable) to 20 bar covered.
  • gas in this case with hydrogen (other gases such as He, N 2 , CO 2, etc., or mixtures thereof are also conceivable) to 20 bar covered.
  • the system has hitherto been covered from a single stack container with a corresponding pressure difference and expanded for recycling into a second stack container.
  • the gas in the stack container is pressed by compressor for recycling in the first stack container.
  • the remaining amount in the cold chamber must be discarded.
  • the filling-side stacking container is replaced by, for example, two stacking containers, For example, the first with an operating pressure up to 20 bar, the second with replaced with an operating pressure of up to 35 bar.
  • the covering of the cold chamber is now done two-stage, first from the first stacking container, then - sensor- and computer-controlled - From the second stack container to operating pressure.
  • the temperature difference between consumer and container is missing, is the Emptying only in one step, in the first stack container, possible.
  • the previously for the relaxation used stack container deleted.
  • the gas losses and thus the Pressure losses must in this case from the storage tank (high-pressure tank) in be compensated for the second stack container.
