tleaville, 0kia., assignmto Phillips Petroleum Company, a corporation Deiawa Application June 9, 1945, Serial No. 598,610 12 Clflml. (CL 62-l) This invention relates to Vaporizers. In a more pecific aspect it relates to Vaporizers for liquefied inflammable gases. In another more systems for the storage.
mixtures thereof.
One object of my invention is to provide a simplified system for vaporizing such gases.
Another object is to vaporize such gases when speciiic' atmospheric heat is insufllcient by applying heat I in a safe manner.
Other objects are to reduce fire hazards and keep vapor lines free from liquid.
Another object is tovaporize and put pressure on such liquefied gases without heating thej'entire liquid content or the storage tank.
Other objects are to provide safe, cheap and economical systems for storing and vaporizing liquid petroleum gas.
.Numerous other objects be apparent to those skilled in the art upon readgas storage and vaporizing system embodying; my invention. V Figure 2 is aview similar to Figure 1 o! a midifled system embodying my invention. I
InFigure 1 a storage tank 3 is provided for liquefied gas 4 and vapors 5 of said gas- Vap rs 5 are led through line B and pressure regulating valve. 1 to line 8. Valve-1 keeps-the pressure in line 8 below a predetermined pressure. Lin
providedjadjacent tank 3 if desired.
A vaporizing tank In is provided having a vapor outlet ll connected to vapor line 3.
33 being conducted through pipe 33 to act against spring 3|.
Bulb 34 is similar to bulb 32 but is exposed to the atmosphere. Bulb 35 is similar to bulb 32 but is exposed to conditions in tank 3.
Pressure from tank 3 is transmitted through line H without involving invention.
A shut-oil valve 31 may be provided in line l2 preferably adjacent tank 3.
In Figure 2 a storage tank 33 is provided with force regulated by bolt 45.
Oitentimes the vapor pressure in tank insui'ilcient and this vapor pressure is increased by vaporizing tank 46 having a vapor exit line 41'.
The vaporizing tank 46 is supplied with liquid through liquid supply line 41 containing regulatfa'f-which is a substantial duplicate of 2,4se,seo
Valve 53 contains a diaphragm 55 and a spring 56 urging valve 51 open. It will be observed that valve N is similarly arranged. A pressure line 58 is provided running from tank as to valve 53. said line 58 may run between tank 38 and valve 53 without being connected to line l1 or may in the alternative run from valve 53 to a point on line 1 between latter arrangement thermal pressure iiuid supply bulb in heat exchange relation with tank transmits pressure through line 80 to valve upon being heated.
To prevent explosions, concentric gauze cylinders GI and 82 may be provided as flame will not travel through these gauze cylinders, the gauze being made out of metal.
shut-oil. valves 83 and 84 may lines I! and 41, respectively.
8 and 54 be provided in Operation The operation of Figure 1 depends on which switches 24, 25, 2B and 21 are closed and which are open.
when the vapor pressure in I is too low, the pressure in the lower portion of valve l3 becomes insumcient to resist the atmospheric pressure and the pressure of the spring inside of valve i3 and liquid flows through pipe I! into vaporizing tank l0. Assuming switches 2t, 25, 26 and 21 to all be open, electric current in line it will flow through switch it, because tank in is cold, and will flow through switch ii if the atmosphere is below a certain temperature. The electricity will necessarily flow through switch it because the pressure in tank 3 transmitted through lines l2 and 36 is insufllcient as set forth above in relation to valve l3. Electricity will then flow through switch iii if bulb 35 is below a predetermined temperature. The electricity will then flow through heating coil H and heat vaporizing tank iii, the electricity then returning through line to the source of electric power (not shown).
Now it bulb 32 is heated above a predetermined temperature, switch IE will open breaking the circuit and stopping the heating in coil ll.
If the atmospheric temperature rises above a predetermined temperature bulb 3| will open switch 11, preventing the heating of coil N.
If the pressure in tank 3 rises above a predetermined pressure, switch is will open stopping the heating of coil ll.
It the temperature in tank 3 rises above a predetermined temperature, bulb 35 will open switch l9, stopping the heating of coil l4.
By means of switches 24, 25, 26 and 21, each one o! switches i8, l1, l8 and I8, respectively, may be eliminated from the system by being shorted or by-passed. This provides a flexible system which will take into account the desired and selected factors and no other factors, but which may be changed to take in other factors by manipulating the proper switches in an obvious manner.
The operation of Figure 2 is similar to that of Figure 1 except that gas burner 48 is employed as a source or heat.
Upon failure or pressure in tank 38, valve 4! opens in a manner similar to valve II and liquid is vaporized in tank 48 because valve 53 has opened as spring 56 is stronger than the pressure in II. Should tank it become overheated, bulb II will operate valve ll to cut of! the gas running to burner 48 and thus prevent further heating or tank ll.
