Definitions
- the invention relates to a method for providing high pressure gas for a Consumer, where the gas liquefies at low pressure in a storage tank is removed, with liquefied gas from the storage container into a storage container introduced and outside the storage container in an evaporator is evaporated, and a gas supply system for providing high pressure gas for a consumer comprising a storage container for storing liquefied gas, one connected to the storage tank via a line Storage container and an evaporator to evaporate the liquefied gas the storage container.
- Gas under high pressure is required for numerous industrial processes. For example is used for laser cutting along the laser beam under high pressure supplied inert gas such as nitrogen to blow out the melt when cutting of a metal.
- inert gas such as nitrogen
- plastic melt is made into a hollow mold introduced, which then with a gas under high pressure on the inner wall the molded part is pressed where it cools.
- Gases with pressures between 30 and 500 bar required in the gaseous or in the supercritical status area.
- the gas is either supplied with gas from cylinder bundles or pressurized gas containers in which the gas is under high pressure, or
- the liquefied gas is conveyed under high pressure to the place of consumption, where it is used of an evaporator is evaporated.
- Part of the liquefied gas withdrawn from a storage tank by a separate Evaporator and then introduced into the head space of the storage container, to increase the pressure there until the desired pressure is reached, with which the gas is to be conveyed to the place of consumption.
- a disadvantage of this method is that the storage container with a capacity of, for example 6000 liters and more must be repeatedly filled with liquefied gas, whereby this refueling takes place against a high pressure in the storage tank, which is considerable Costs.
- the high pressure gas at the point of use if possible with a pressure specified by the consumer can be put.
- there should be a deployment for a consumer network can be ensured, but also a fluctuating in demand or even intermittent gas consumption (occasional use of a consumer system) to be possible.
- This object is achieved for the method according to the invention in that the gas obtained by the evaporation of the liquefied gas at least partially is used to drive a piston of a working cylinder and with the help of the working cylinder a piston of a pump cylinder is driven, which liquefies Pumps gas from the previous day container to the evaporator, and that over the pumping and Evaporation of a gas at a pressure higher than that required by the consumer High pressure is obtained.
- the pump cylinder is advantageously operated with a suction and pump cycle, where liquefied gas is sucked out of the storage container in the suction cycle and in Pump cycle is pumped to the evaporator.
- the working cylinder can take two work cycles are operated, with a corresponding cyclical switching of the supply the gas from the evaporation to drive the piston of the working cylinder.
- excellent results were obtained with a ratio achieved by 1: 3.
- the object is thereby for the gas supply system according to the invention solved that a pump cylinder with pistons for pumping liquefied gas the previous day container is provided which one with a vaporized via a piston Gas-fed working cylinder is driven.
- the working cylinder and the pump cylinder are advantageously in one unit arranged, the pistons of the two cylinders, for example, via a piston rod are interconnected.
- a control device for the exact setting of the pressure to the required working pressure brings additional benefits for the consumer and makes the system flexible.
- a switch block that is one of the piston movement of the working cylinder dependent regulation includes.
- Shut-off devices can be attached at various points: In the line from the evaporator to the working cylinder or, if necessary, to the means for clockwise Switching the gas supply for the working cylinder, in the line from the headspace of the storage container to the head space of the storage container or in the line for liquefied gas from the storage tank to the previous day tank.
- the latter line should be chosen as short as possible.
- the previous day container can be equipped with a level control.
- the invention can also be used in the supercritical state for all suitable gases or gas mixtures.
- the invention can also be used for gases such as CO 2 , however evaporation by means of a heating medium and not with air is then recommended.
- the storage container or liquid tank T which is filled with liquid nitrogen, for example, is connected via a line to the valve V1 for liquid N 2 and a line with valve V5 for gaseous N 2 from the head space of the storage container T to a pressure booster system DEA .
- the DEA pressure booster system has a connection for liquid N 2 and a connection for gaseous N 2 .
- the pressure booster DEA leads a line for liquid N 2 to the evaporator VD. From this evaporator VD, the evaporated and therefore gaseous N 2 is passed under an evaporator pressure into the pressure booster system DEA via the connection returned. Via connection the gas reaches the consumer or a consumer network at the desired high pressure.
- FIG. 2 shows the pressure booster DEA with individual details. Their function is described below.
- liquid connection liquid nitrogen runs into a receiver or cooling container B.
- gaseous nitrogen is passed via the gas pendulum connection or ball valve 8 via connection V into the head space of the storage tank T (geodetic inlet).
- This geodetic inflow is interrupted by a level controller 1 when a predetermined maximum fill level in container B is reached.
- the pump cylinder 2 sucks in liquid nitrogen via the suction valve 10.
- the liquid nitrogen is connected via the pressure valve 11 directed to the high pressure evaporator VD.
- the gaseous high-pressure nitrogen passes through the connection back to the DEA pressure booster system.
- the high-pressure nitrogen is used as the drive gas the cylinder 3 of the unit A needed. After the work cycle, the nitrogen fed into the consumer network via the working pressure regulator 21 (IV).
- the DEA pressure booster system requires a pressure difference between to function High pressure gas from the evaporator VD and that required by the consumer Working pressure. In the system shown, this ratio is, for example 1.65. This means that the pressure in the evaporator VD is 1.65 times higher than the pressure in the consumer network. With an assumed maximum working pressure for to the consumer of 100 bar, this means an evaporator pressure of 165 bar. Of the The evaporator must therefore correspond to the specification of the maximum required working pressure be designed for the consumer.
- the switch block 13 switches the high pressure nitrogen between the top of the piston and piston underside and relaxes the opposite cylinder chamber of the working cylinder 3. This creates the up-and-down movement that the piston drives in the pump cylinder 2. The movement is transmitted via the one shown Piston rod, which is sealed to the wall of unit A, so that the working cylinder space is separated from the pump cylinder space. After the switch block 13 the nitrogen reaches the working pressure regulator via a non-return valve 21. This pressure regulator 21 has the task of keeping the high pressure constant for the consumer to keep.
- the pressure in front of the regulator increases 21 on. This automatically slows down the DEA pressure booster system.
- the Pressure booster system DEA thus adapts itself to changing load conditions on.
- the start-up controller 20 monitors the evaporator pressure of the pressure booster system DEA. If it drops too low - for example 5 bar below the setpoint - it will automatically the start controller 20 is open. The starting controller 20 relaxes the line the switching block 13. In this way, the pressure booster system DEA a few quick cycles of unit A quickly build up the evaporator pressure again and the starting controller 20 closes again. The Pressure booster system DEA also against high pressure in the consumer network be started.
- the supply line from the connection to the evaporator VD as well as the return line from the evaporator VD to the connection have no shut-off device.
- the DEA pressure booster system is commissioned as follows: A possibly existing (not shown) gas supply valve of the Storage tank is opened. A possibly existing (not shown) Pressure regulator must be set to a pressure - for example 6.5 bar - that he can build up to a maximum.
- the DEA pressure booster system has one Pressure reduction regulator 15, which is at a certain value - for example 8.5 bar - is set so that it regulates at this 8.5 bar.
- the pressure for the operating gas - for example 6 bar - set.
- the gas supply to the consumer should be closed.
- Valve 26 must be closed.
- the pressure setpoint is to be set on the adjusting piston regulator 17.
- the Cooling tank B After slowly opening valve V1 in the liquid supply line, the Cooling tank B is filled and the DEA pressure booster system is automatically brought up to operating temperature cooled down. This process takes about 15 minutes. Now the pressure booster system DEA ready to start.
- the system After opening the valve 26, the system begins to work.
- the starting controller 20 is opened and blows nitrogen out through a silencer. this happens until the set operating pressure is reached.
- the DEA pressure booster system automatically adjusts its working speed the gas consumption by the consumer. Should the form of the pressure booster system If the DEA sinks too low, the starting controller 20 is opened automatically.
- the pressure booster DEA is switched off by closing the N 2 liquid valve V1 on the storage tank T. Then the valve 25 of the pressure booster DEA is closed. The gas supply valve V5 remains open.
- the shut-off valve V1 for liquid nitrogen at the storage tank T can be opened.
- a limit switch 4 for the working cylinder 3 is also shown, the Limit switch 4 in connection with a valve 5, the level controller 1, the operating gas controller 16 and a valve 6 connected to the switch block 13.
- a seal monitoring in the exemplary embodiment 7 is attached.
- the template or cooling container B is also with a safety valve 9 and one with a vent valve 12 line to a liquid pressure limiter 18 equipped, the liquid pressure limiter 18 in connection with the line to Liquid connection II to the evaporator is available. Finally, there is a gas pressure limiter 19 provided in the line from the gas connection III by the evaporator. Via an adjustment cylinder 14, the liquid pressure limiter 18, the gas pressure limiter 19, the start-up regulator 20 and the working pressure regulator 21 can be set. In Figure 2 is in Area of the starting controller 20, a pre-pressure indicator 22 and a back pressure indicator 23, as well as a working pressure display 24 for the working pressure regulator 21.
- the DEA pressure booster system does not require any use of air evaporators External energy to increase pressure.
- the total required drive power is the Environment by evaporation of the liquefied gas against air.
- the essential The idea of the invention lies in the evaporation of liquefied gas volume increase occurring to drive the unit.
