Description
SPECIFICATION
Filling bottles
This invention relates to an apparatus and a method for filling compressed gas bottles with a quantity of compressed gas determined on the basis of mass.
The filling of compressed gas bottles is a common practice. A bottle, or a cylinder as they are often referred to, cannot legally contain more
CO2 than 68% by weight of its water capacity. For example, if a bottle will hold 100 units of weight of water when filled, it should not have more than 68 units of weight of CO2. If a bottle is overfilled, excessive pressure may develop and burst a rupture disc, depending on amount of overfill and temperature. The only known and used safety device for compressed gas bottles are rupture discs. Only one rupture disc of the proper type, material and manufacturer should be used on any one bottle. One of the problems previously seen is that people install two or more rupture discs, the wrong disc, or back-up the rupture disc with a coin or slug and the rupture disc becomes inoperative.In many instances like this, a bottle has exploded with loss of property, limb, and even life. The bottles travel in commerce and for the most part it is impossible to easily ascertain if a rupture disc has been rendered inoperative by other parties. Cylinder filling is critical; incorrect filling may cause hazards, and safety cannot be overemphasised.
CO2 is measured by weight. CO2 can be filled by gravity or from extremely high pressure dry ice converters. Most CO2 filling is one with pumps.
CO2 filling pumps are made by Liquid Carbonic
Division of General Dynamics and by Walter Kidde
Company. Use of a suitable CO2 filling pump offers the most convenient and most efficient method of filling bottles and blow down and/or cooling purges of bottles is not necessary to obtain a full fill.
Regardless of the known filling methods selected and regardless of the apparatus employed, a scale, such as a recommended beam scale meeting regulatory accuracy requirements, must be used to determine when a bottle is properly filled. This is done by voiding the bottle and determining its empty or tare weight. To the tare weight is added its CO2 capacity in pounds, and then the bottle is filled to such gross weight.
There are many problems including significant variance in bottle weight and lack of an automatic shut-off. No one has devised a weighing device which is sufficiently accurate to be trusted during filling; the bottle must again be weighted after filling. Mistakes are commonplace and over and under fill a frequent occurrence: mistakes and oversights can produce explosive results.
CO2 is very difficult compressed gas to fill and to measure. At -56.60C, CO2 exists as a solid and a vapour; at 21 0C, CO2 exists as a solid, liquid or vapour; between -56"C and +31 OC, CO2 exists as a vapour and a liquid; above 31 C, all CO2 exists as a vapour. Compressed gas bottles are usually filled with compressed CO2 in its liquid form. Liquid CO2 is highly compressible at temperatures approaching normal ambient temperatures and the quantity of CO2 cannot be accurately determined on a volumetric basis. For example, at 31 0C and 73,000 g/cm2, the specific gravity of CO2 is about 0.59, whereas at 98,000 g/cm2 the specific gravity is about 0.77.As a further example, at 250C and 70,000 g/cm2 the specific gravity of 0.74 and at 98,000 g/cm2 the specific gravity is 0.84. At OOC and 98,000 g/cm2 the specific gravity is 0.96.
There is a trend toward smaller bottles, specifically about 2 Kg and 1 Kg bottles. It becomes extremely difficult to fill these bottles based upon weight because the bottles vary significantly in their metal content and the total weight is quite small and these small bottles are almost impossible to weigh during filling because the hose connections are an influence of erratic quantity. There is no apparatus or method enabling a retainer to fill these small bottles efficiently and safely.
By the present invention there is provided apparatus for filling compressed gas bottles with a predetermined mass of highly compressed gas, comprising: a an inlet for being fluidly connected to a
source of compressed gas; b a pump for compressed gas, said pump being
fluidly connected to said inlet; c a mass flow meter fluidly connected to an
outlet of said pump, said flow meter having
means for producing a signal for a unit of
mass of highly compressed gas which has
passed through said flow meter; d a normally closed fill valve fluidly connected
to an outlet of said flow meter; e a bottle connector downstream of said fill
valve for fluidly connecting an outlet of said
fill valve to a compressed gas bottle to be
filled, for filling the bottle from the bottle
connector; f means for opening said fill valve; and g means operatively connected to said mass
flow meter and the fill valve for quantifying
the accumulative additive count of signals
from the mass flow meter and for closing the
fill valve upon reaching a predetermined
accumulative additive count of signals, said
predetermined count being indicative of a
predetermined cumulative quantity of units of
mass which cumulatively total a
predetermined and quantified mass of
compressed gas filled into the bottle.
There may be provided means for powering said pump, said means normally energising said pump. The signal producing means may be normally energised. The mass flow meter may be devoid of internal obstructions. There may be provided means for gramming the quantifying means.
There may be provided means downstream of the fill valve for venting compressed gas between the fill valve and the bottle. The venting means may comprise a valve fluidly connected to the fill valve outlet and the bottle connector. The venting means may be normally open and may be operatively connected so as to be closed when the fill valve is opened. The venting means and the fill valve may be connected in parallel for simultaneous operation.
There may be provided a flow restrictor in the venting means, the flow restrictor being a reduced diameter tube upstream of the venting means, for reducing the volume to be vented.
The present invention further provides a method of filling compressed gas bottles with a predetermined mass of compressed gas, comprising the steps of: a propelling compressed gas into a bottle; b measuring the mass flow of the compressed
gas prior to acceptance of the compressed
gas within the bottle; c generating a signal proportionate to the
amount of mass per unit of time flowing
into the bottle; d accumulating the signals; and e terminating the flow of compressed gas into
the bottle upon accumulation of a
predetermined number of signals, said
predetermined number of signals being
directly correlatable to a predetermined
quantity of mass of the compressed gas.
The step of propelling may include the step of automatic pumping in response to fluidly connecting an empty bottle to a compressed gas pump. The measuring may be done between the pump and the bottle. The measuring may include the step of continually exciting the means for generating the signal. The filling of the bottle may be carried out through the automatically closing outlet valve on the bottle and opening the outlet valve with the flow of compressed gas. The termination of flow into the bottle may be by closing a valve adjacent to and in direct fluid communication with the bottle, including the further step of venting to atmosphere the compressed gas between the valve and the bottle prior to disconnecting the bottle from direct fluid communication with the valve.
The flow of compressed gas may be restricted during venting.
Closure of the fill valve and venting valve may be simultaneous.
The compressed gas may be carbon dioxide.
The compressed gas may be highly compressed and in a substantially liquid state. The compressed gas may have a specific gravity of at least 0.5. The compressed gas may be liquefied.
By way of example embodiments of the present invention will now be described with reference to the accompanying drawings, of which
Figure 1 is a schematic diagram of the apparatus of the preferred embodiment of this invention; and
Figure 2 is a detail view of structure for connecting the apparatus according to Figure 1 to a compressed gas bottie.
The apparatus of the present invention is generally indicated by the numeral 10 in Figure 1.
The apparatus 10 has a compressed gas fluid line 1 5 having a fluid inlet 11 for being connected to a bulk source 12 of compressed gas. The source 12 may be a large cylinder or a bulk tank; the expected compresed gas is highly compressed carbon dioxide substantially in a liquid state at a pressure of 100,000 g/cm2 more or less.
Downstream of the fluid inlet 11 is a check valve 1 3 for preventing loss of compressed gas when the fluid inlet 11 is disconnected and a change is made in the source 12. Further downstream of the fluid inlet 11 is a relief valve 14 which will open when pressure in the compressed gas line 1 5 exceeds 100,000 g/cm2. A high pressure pump 16 is fluidly connected to draw compressed gas from the source 12 and to propel the compressed gas through a mass flow meter, generally indicated by the numeral 17, to a bottle connector 18. The pump 1 6 is of a known type and may be either electrical or pneumatic powered. A pneumatic power line 1 9 supplies compressed propellant to the pump 1 6.
Downstream of the pump 1 6 is a second relief valve 20 which will open if pressure downstream of the pump 1 6 exceeds 100,000 g/cm2.
Downstream of the mass flow meter 17 is a normally closed solenoid powered valve 21 hereinafter referred to as the fill valve 21.
Between the fill valve 21 and the bottle connector 1 8 is a solenoid powered normally open vent valve 22 fluidly connected to the line 1 5 by a very small diameter refrigerant capillary tube 23. The bottle connector 1 8 has a seal 24 and is adapted to sealingly receive the neck of a compressed gas bottle 26. Within the bottle neck 25 is a one-way valve 27, commonly referred to as a Schrader valve of the same type as used in tubes and tyres.
The volume of the line 1 5 downstream of the fill valve 21 is intentionally minimised by the usage of the capillary tube 23 which effectively minimises the loss of gas during venting by opening of the vent valve 22 prior to disconnection of a bottle 26 from the bottle connector 1 8.
The mass flow meter 1 7 is connected to a signal counting controller 28 which is operatively connected to the fill valve 21 and vent valve 22; the valves 21,22 are connected in parallel to the controller 28. The mass flow meter 1 7 has a Ushaped torque tube 30 which is a part of the fluid line 1 5 and which is wide open and devoid of obstructions to fluid flow. The tube 30 is continually vibrated by an electromagnet 31.
When there is movement of a mass through the tube 30, the moving mass exerts a torque upon the tube 30 and sensors 32 detect and measure the torsional twist of the tube 30. The sensors 32 may be either magnetic or electro-optical and are connected to the controller 24. Whenever the tube 30 twists, the sensors 32 detect the twist and send a signal to the counter 24 that is directly proportional to the mass that is flowing through the tube 30 during the period of time of measurement. The tube 30 is excited at a suitable frequency anywhere between 0-1 5,000 Hz. The increment of time for a measurement of a unit of mass, and the quantity of a unit of mass can both be very small.The preferred mass flow meter is made by Micro Motion, Boulder, Colorado, is referred to as a Model C and is represented as being the subject of US Patents 4,109,523; 4,109,524 and 4,187,721. .
The controller 24 is a multi-decade electronic predetermining counter, An upper window has a multi-digit LED read-out window 35 and the controller 24 can be adjusted or programmed by thumbwheel switches 36 to enter a predetermined accumulated additive count required by the controller 24 for an output signal by the controller 24. A reset switch 37 is provided to return the controller 24 to zero after a fill cycle and a start switch 38 will initiate a fill cycle. The preferred controller 24 is a Model 7907 by
Veeder-Root, Digital Systems Division, of
Hartford, Connecticut. The controller 24 is continually energised as is the mass flow meter exciter magnet 31. If the pump 16 is electrical, the pump 1 6 is also continually energised.
In the method of the present invention and in operation of the apparatus 10, the inlet 11 is connected to a supply of compressed gas; the specific intended gas is carbon dioxide. The pump 1 6 begins to propel compressed gas through the line 15 and fills the line 15 to the fill valve 21. The compressed gas is highly compressed and is substantially in a liquid state in the source 12 and throughout the line 1 5. The check valve 13 prevents backflow or emptying of the line 1 5 during changing of supplies 12, and minimises the loss of compressed gas. If pressure within the line 1 5 goes above 100,000 g/cm2, either or both of relief valves 14, 20 will open and relieve down to 100,000 g/cm2.When the line 1 5 is filled, the pump 1 6 stops due to back pressure and/or hydrostatic lock even though the propellant line
19 is kept pressurised and the pump 1 6 is continually energised and ready to go.
A gas bottle 26 is prepared for filling by first being placed upside down in a cage. The valve 27 is opened and the bottle 26 is completely voided.
The bottle is then weighed on a pro-calibrated scale to be certain there is no water, remaining gas or foreign material in the bottle. The gas bottle 26 is then placed in the apparatus 10 and the bottle neck 25 is held in the bottle connector 1 8 and against the seal 1 8. The reset 37 is used to reset the controller 28 and the LED window 35 to zero or an appropriate base. The switches 36
have been previously adjusted to pre-program the controller 28 for terminating fill upon receipt of a predetermined quantity of signals from the mass flow control 1 7.
The operator of the apparatus 10 actuates the start button 38 and the controller 28 effects simultaneous opening of the fill valve 21 and closing of the vent valve 22. Highly compressed gas, specifically highly compressed carbon dioxide gas which is substantially in a liquid state, is propelled by the pressure of the source 12 and the pump 16 through the fill valve 21 and through the bottle valve 27 and into the bottle 26.
Any and all flow of the highly compressed gas through the mass flow meter 1 7 effects a torque upon the U-shaped tube 30 and the mass flow meter measures this flow on the basis of mass.
The tube is continually vibrated at 0-1 5,000 Hz, but the vibration is linear in the absence of flow.
During flow, the tube 30 twists and the sensors 32 detect the twist which is proportional only and directly to the mass flow through the tube 30, the twist ignores the constraints of pressure, temperature, density, compressibility of liquid carbon dioxide, velocity and liquid or vapour state.
The tube twists directly proportional to the mass flow. The sensors send a signal during each twist of the tube 30 that is proportionate to and which indicates how many units of mass flowed through the tube 30 during the time period of the twist.
The controller 28, which is also a counter, accumulates the signals and when a predetermined additive count matches the preset number count previously entered with the thumbwheel switches 36, the controller 28 fires an output that will terminate flow by simultaneously closing the fill valve 21 and opening the vent valve 22. The pump 1 6 remains energized and ceases to operate because of hydrostatic back pressure. The second relief valve 20 protects that part of the line downstream of the pump 16. The exciter 31 remains energised and the tube 30 keeps vibrating. The LED window 35 will indicate how many units of highly compressed gas have passed through the mass flow meter 1 7. The accuracy of the measurement is + > % based upon mass. When flow is terminated, the bottle valve 27 will automatically close.
Opening of the vent valve 22 vents to atmosphere the compressed gas between the fill valve 21 and the bottle 26 prior to the bottle 26 being disconnected from the bottle connector 18.
This venting prevents compressed gas from blowing out on an operator of the apparatus 10 when the bottle 26 is disconnected. During the venting, the flow of compressed gas is restricted by small tube 23. The small tube 23, which is preferably a capillary tube, also reduces the volume of the line 1 5 in between the fill valve 21
and the bottle 26. The restricting of the vented flow also eliminates the loud noise of sudden release of the compressed gas.
The improved apparatus and method of this
invention enable accurate and safe filling of
relatively small compressed gas bottles with
liquid carbon dioxide. A specific small bottle has a
capacity of about 1 Kg and is an aluminium bottle
by Luxfer. This invention will enable retainers,
such as large grocery stores, to refill carbon dioxide bottles for domestic soft drink, wine and beer systems.
