Definitions

• the present invention relates to a gas filling station with intermediate storage for charging high-pressure storage bottles.
• the rate of charging from the intermediate store e.g. from the compressor store
• the compressor is a decisive functional and economic factor, which is limited by the heating caused by the process heat:
• diving air bottles to 200 bar
• the bottle to be filled is often immersed in water so that the filling speed increases.
• the present invention has for its object to provide a device that prevents heating when charging high-pressure bottles with gas.
• a rinsing pump assigned to the bottle to be charged and under bottle pressure circulates the bottle volume via a return line and limits the temperature fluctuation of the charging process either by means of a heat exchanger or by mixing with the contents of the intermediate store; for this purpose the bottle has two connections which are arranged in such a way that the best possible volume exchange takes place during circulation.
• FIG. 1 shows a charging system with mixing
• FIG. 2 a charging system with a heat exchanger can be seen
• Fig. 3 is a flushable bottle in section with a typical application in the form of a barrier actuation.
• the gas filling station with mixing consists of an intermediate store 1, which is kept at a predetermined operating pressure by a high-pressure compressor 2, which is not specifically defined here, a throttle orifice 3, which determines the speed of charging, and a feed-side quick-coupling half 4 on the feed line 5.
• the flush line 6 opens into the intermediate store 1, which is connected to the flush-side quick coupling half 8 via the flush pump 7.
• the flushing pump 7 is accommodated together with its drive in a pressure container 10 which is under bottle pressure.
• a differential pressure switch 9 as a control of the flushing pump 7 bridges the throttle diaphragm 3, a temperature sensor 14 on the flushing line 6 is used to automate the charging process.
• the bottle side of the charging system consists of the flushable bottle 11 (shown here as the energy storage of a forklift) with 2 connections, each of which is connected to the feed side 12 and flush side 13 quick coupling halves.
• the high-pressure intermediate store 1 is connected to the bottle 11 to be charged via the quick coupling system 4/8/12/13, gas flows through the orifice 3 into the bottle 11 as long as there is a pressure drop between the two containers. While this pressure drop exists, it will keep the differential pressure switch 9 on the throttle orifice 3 open. Only when the pressure equalization process has ended, ie when the content of the bottle 11 is heated and the content of the intermediate store 1 is cooler, does the differential pressure switch 9 switch on the flushing pump 7, which ensures the heat exchange between the bottle 11 and the intermediate store 1 by mixing.
• the temperature sensor 14 switches off the flushing pump 7 as soon as the gas flowing through the flushing line 6 has approximately reached the ambient temperature.
• the winding pump 7 therefore only has to overcome the pressure drops in the lines and couplings, since the throttle point 3 is expediently designed as a differential pressure-controlled current controller, which is therefore fully open when the pressure is equalized, thus also accelerating the pressure equalization process, which corresponds to the warming phase of the bottle 11, which is said to be so be as short as possible so that as little heat as possible penetrates the bottle wall
• the charge with circulation through the heat exchanger prevents the build-up of heat in the bottle 11 'at all times and thus protects heat-sensitive designs, the system is indispensable for charging directly from the compressor and if the pressure cannot be fully equalized (partial charge of the winding pump 7 can occur due to the permanent Pressure difference must not be switched on)
• the heat exchanger 15 ' can be arranged outside the system (e.g. in the case of direct compressor charging), e.g. in the ground are used
• FIG. 3 shows a section through a commercially available gas bottle 18, which is converted into a spoolable storage device by a second connection with a tubular extension 19 can be connected to the charging system by the quick couplings 12713 "; as a simple application for air as gas, an actuation for the barrier 23 is shown here, which is moved via the pressure reducing valve 20 and the control valve 21 by means of a single-acting cylinder 22. There is one in the cylinder 22 Double chamber 24 (hatched) filled with oil, whereby the movement can be braked via the throttle valve 25, and the requirements for the silencer 26 remain modest.
