' 7 Claims. (01. 62-1) This invention relates to an improvement in butane systems for vaporization of hydrocarbon fuel such as butane or the like. 7
In many systems used heretofore for the storage and dispensing of liquefied hydrocarbon gases,
be combustible readily unless more primary and secondary air is added.
The object of'this invention is to improve the dispensing system to insure that all of the fuel supplied to the point of use will be completely and thoroughly vaporized. Due to a constant dewpointor boiling point there is little likelihood of condensation in the conduit.
This object is accomplished preferably by a heat exchange relation between the'conduit and a liquid that is circulated therearound in a thermo-syphon circulating system, which preferably has a section in the body of fuel in the tank to .utilize the sensible heat thereof for circulating said liquid and for vaporizing the fuel in the tank.
This preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
Fig.) is a verticalsectional view through the storage tank and circulating tank, with pipe connections in elevation;
Fig. 2 is a vertical sectional view therethrough on the line 2--2 of Fig. 1; and
Fig. 3 is a plan view of the filling housing, with portions broken away.
The numeral I represents a storage tank designed to contain liquefied gaseous fuel under sufficient pressure to maintain the same in aliquid condition. The fuel usually employed con-- tains a mixture of hydrocarbons with a high percentage of butane, or is essentially liquefied butane gas, that may be held as a body of liquid in the tank I. This tank is preferably buried in the ground in the usual way, although this q is not essential, but when buried, the temperature of the earth aids in maintaining the liquefied gas in the proper condition for use.
Extending into the tank I is a withdrawal tube. {which terminates adjacent the bottom ofqthe tank to withdraw the fuel therefrom in the liquid phase. At its upper end the liquid with# drawal tube 2 is connected with an automatic point of use.
shut-oif valve 3 and manual control valve 4, to a high pressure regulator 5. Said regulatoris of the usual character designed to reduce the pressure of the fuel passing therethrough, and to ac complish an initial vaporization thereof.
From the regulator 5 extends a pipe line 6 which passes into a tank 1, shown as supported above the storage tank I and as auxiliary there- The pipe preferably extends through the auxiliary tank I in the form of a coil 8 to increase the heat exchange relation with the interior of the tank. From the coil 8 the pipe extends to a low pressure regulator shown at 9 from which the service pipe I ll extends to the In passing through this line 2-40, the liquefied gas is initially withdrawn from the tank I, vaporized in passing through the first stage regulator 5, and normally would be still further vaporized at a lower pressure in passing through the second stage regulator 9 to the point of consumption. However, not all of the liquefied gas is initially vaporized in passing through the regulator 5, or recondenses thereafter, and to insure of a complete vaporization thereof and of a revaporization of any condensed gas, it is circulated through the coil 8 which is immersed in a low freezing liquid in the auxiliary tank I. This liquid may be of the character of pentane orke'rosene which will warm the gas flowing through the coil 8 to maintain the gaseous condition thereof or to revaporize the same if it should be condensed.
The auxiliary tank I is connected in a thermo syphon circulating system which includes a coil ll disposed in the bottom portion of the tank I will tend to chill the body of liquid substantially filling said tank around the coil 8, which will cause the thermal instability in the circulating system ll-H, whereby the circulating liquid from the tank I will flow downward from the coldest part of the tank I through the pipe I3 and coil ll, being warmed by the sensible heat of the body of liquefied fuel in the tank I, and then the warming of said liquid in the circulating system will cause it to flow up through the pipe M to the top of the auxiliary tank E. This circulation ofthe warmer liquid from the tank l around the coil 8 will cause a vaporization or revaporization of any liquefied or condensed fuel passing through or in the coil.
Pipes i and it are attached to the 'top of the tank 5 to allow for the filling of the tank with the liquid butane. A gauge device l? is provided in the tank for the purpose of determining the liquid level for the body of fuel therein. A pressure gauge 58 (Fig. 3) may be provided also, connected with the pipe t, to determine the pressure in the system.
These filling and gauging devices are preferably enclosed in a housing l9 provided with a hinged cover 20 located at or above the surface of the ground for access thereto, which housing may be filled with insulting material, if desired.
A filling pipe 2! is shown for the auxiliary tank i to insure of this tank being constantly filled to obtain the proper flow of the warming liquid through the thermo-syphon system.
