DIP-PIPE FOR GAS APPARATUS.
SPECIFICATION forming part of Letters Patent-No. 731,673, dated J une 23, 1903.
' Application filed August 22, 1902. Serial No; 120,728. (No model.)
i do hereby declare the following to be a full,
clear, and exact description of the invention,
such as will enable others skilled in the art to fwhichit appertains to make and use the same.
This invention relates to apparatus for controlling the separation and discharge of liquids of difierentgravities and for maintaining the desired depth of seal on the dippipes in hydraulic mains of gaswvorks, or in other situations where liquids of different specific gravities are to be removed from a container and a fiz'ced level of liquor main- WVhen such device is applied to the hydraulic main of a gas-works, the object is to provide for the separate displacement or removal of'tar from the lower level of the hydraulic main through ,a separate overflow; also, to provide a suitable overflow for excess of ammoniacal liquor or water that may be delivered into or condensed in said hydraulic main, said overflow being so constructed as to form a skimmer that in'working practice will remove from the surface of said liquor or water any soot, lanipblack, or other substance that may float thereon, such prompt removal or separation resulting in preventing the same from mixing with and contaminating the tar that may be contained in or passing through the hydraulic main at the moment. The matter constituting my invention will be defined in the claims.
I will now describe the details of construction and arrangement of my improved apparatus by reference to the accompanying drawings, in which- Figure 1 represents a sectional front elevation of an end portion of the hydraulic main, a tar-receiving tank, separating devices, and connections. Fig. 2 represents an elevation, partly insection 011 the line 2 2, Fig. 1, of the tar-receiving tank. Fig. 3 represents a sectional modification of the tar-tank, showing a diaphragm construction'that may be employed in lieu of the pipe connection shown in Fig. 1 and a modified construction of overfiow device that may be employed for the removal of tar from said tank. Fig. 4 represents a top plan view of the apparatus, partlyin horizontal section. Fig. 5 represents a top plan view, on enlarged scale, of the soot-skimmer and Water-overflow device. Fig. 6 represents afront view of said soot-skimmer and wateroverflow device. Fig. 7 represents a transverse section of the soot-skimmer and overflow device.
Above the retort bench or furnace A is set the hydraulic main B in the usual manner and has projecting down into it the dip-pipes E, which'in practice connect with the retorts. (Not here shown.) The hydraulic main is provided with the gas-outlet O.
A supply-pipe K, leading from the main 0, projects down and through the top of the hydraulic main B nearlyto the bottom thereof and is provided at its lower end with a discharge-nozzle 7.6 for admitting warm ammoniacal liquor or water, preferably at a temperature of about 17 0 Fahrenheit, for the purpose of washing the main free from tar. The main 0 is supplied with ammoniacal liquor or water under pressure from a tank or pump from some convenient source, but preferably from a settling-tank or separator. The warm ammon iacal liquor or water is circulated through the main for Washing out therefrom either freshly deposited or accumulated tar and then is conducted to the settling-tank,where it is freed from soot, dust, floatingtar, or other suspended matter and is again pumped or otherwise forced through the main 0 and pipe K into the hydraulic main B.
I11 carrying out my invention I provide two distinct overflow devicesone for water or liquor of lighter specific gravity overflowing at a higher level and the other for the re moval of tar or other liquid of heavier-specific gravity fixed at a lower levelthe height of one overfi my device above the other being suflicient to cause the complete or nearly'oom plete separation of the two liquids to} be removed, according to the requirements of the peculiar specific gravity of each liquid. I will now particularly describe the construction and arrangement of these overflow devices.
'ferent conditions and requirements.
In connection with the hydraulic main I provide a tar receiving and separating tank D, resting. upon a bracket or other suitable support T and connecting to the hydraulic main by a short pipe connection G in such a manner as to permit the free flow of tar from the bottom of the main into the interior of said tank, as shown in Fig. 1. A gate-valve F, havin a stem f and hand-wheel) is fitted in the pipe connection G for shutting off the flow of liquor from the hydraulic main to the tank D when it is desired to clean or repair either the main or any portion of the tank D and its pipe connections.
The skimmer and overflow device H for liquids of lighter gravity is preferably placedacross the main B and has a bottom opening Y 00, with which connects the overflow dischargepipe R, extending down to a separating-tank. (Not here shown.) The skimmer II is in the nature of a cup having a straight side with an upWardly-projecting lip 7L, placed adjacent to the end of the main, and a curved or semicylindrical side h, placed toward the dippipes E. As will be noted by reference to Figs. 6 and 7, the curved side h is at alower level than the lip 7L, so as to permit the overflow of water or light liquid carrying floating soot or lampblack or lighter particles of tar. The skimming device H is supported a short distance above the bottom of the main B for permitting the passage of tar below the same and thence through the pipe connection G into the tank D.
The overflow-pipe R, which connects with the bottom of skimmer H, passes through a stuffing-box? and is supported by the bracket Q. The pipe R at the level of the fork q is screw-threaded and has applied thereto an adj usting-nut 0", arranged in the fork q of the bracket Q, for vertically adjusting the skimmer H to the proper height in the main B to provide a sufficient depth of liquid in the main to properly seal the lower ends of the dip-pipes E. By this vertical adjustment of the skimmer H the depth of seal on the lower ends of the dip-pipes can be varied to suit dif- By means of the transverse arrangement of the skimmer H across the entire width of the main B and the upwardly-projecting lip h of said skimmer the excess of Water and contained particles of soot and other suspended matter are arrested and conducted by pipe R to a separating-tank. (Not here shown.)
The tar-receiving tank D is supported on a bracket T and is provided at the top with an opening having a tight-fitting lid d and on its side, near the bottom, with other openings having lids cl (7,. A tar-outlet pipe I is so placed in tank D that its upper open end i shall be above the liquid-level in the hydraulic main and that its lower end 7; shall extend down into the tar near the bottom of the tank,
as shown in Fig. 2, and it is provided with a lateral outlet branch 1', passing through the side of the tank where it connects with the tar-overflow chamber L. This overfl ow-chamber L is closed at top and bottom and has a lateral clean-out opening closed by a lid 41. The tar-escape pipe L passes up through the bottom of chamber L and has a screw-threaded upper end Z for receiving the screw-threaded section Z for controlling the height of the overflow. This section Z is provided at the top with a bail or curved bar g, to which is connected the rod J, passing through a stuffing-box in the top of the chamber and having a pointer j and at the top a hand-wheel A graduated gage Z is secured to the top of the chamber adjacent to the rod J and its pointer j for indicating the height of the adjustable overflow-'sectionl. Itwillbe understood that by turning the screw-threaded section Z it may be adjusted up or down on the screw-threaded portion 1 of pipe L, and thus regulate the height of the tar in the overflowchamber L. It will be noted that the level of the tar-overflow is below the level of the ammoniacal liquor in the hydraulic main B and the tank D. The tar-escape pipe L will in practice connect with the usual tar-pot. (Not here shown.) The hydraulic main B, tar-tank D, and overflow-chamber L are connected by equalizing-pipes 8, having valves, as shown in Fig. 4, for the purpose of maintaining and equalizing the gas pressure throughout the apparatus, so that the liquidlevels may be properly balanced and maintained. The tar-discharge pipe L is provided with a branch steam-inlet pipe N, having a valve 17., and with valves 0 and 0, placed respectively above and below said steam-pipe, as shown in Fig. 2. By means of this pipe N steam may be admitted to pipe L for soften ing and cleaning out tar or other accumul-ations therein. By closing the lower valve 0 steam may be passed upward for cleaning the upper portion of pipe L, and by closing valve 0 and opening valve 0 steam will be admitted to the lower portion of the pipe L. The pipe L having been properly cleaned the steamvalve 01 is closed and both valves 0 and 0 are opened for continuing the operation of the apparatus. The liquid-discharge pipe R may be provided with similar valves and a steamsupply pipe for cleaning it. A steam-coil P, having inlet and outlet pipes provided with valves 1) p, is placed in the tar-tank D near its lower end for keeping the tar warm and fluid, so that it will readily flow off through pipe I and the overflow-chamber L. The tank D is also provided at the bottom with a drainpipe S for drawing off at suitable intervals a portion or all of the accumulated tar, as occasion may demand.
In the modified construction of the tar-tank shown in Fig. 3 a vertical diaphragm M is substituted for the outlet-pipe I shown in Fig. 2, and the overflow-chamber L is secured to one side of the tank, connecting with the tar- IIO outlet compartment thereof; but I prefer the construction shown in Fig. 2.
To the lower end of the water-supply pipe K in the hydraulic main is applied a jet-nozpractically free from tar.
zle k, composed of a cap which is slotted to form a suitable jet-orifice for the discharge of water or ammonia liquor near the bottom of the hydraulic main and preferably in the direction of the overflow and the outlet pipes leading from the main. Anumber of these pipes K with jet-nozzles are placed at different points along the length of the hydraulic main, so as to keep the main ,well washed and v The discharge of jets of warm or heated ammoniacal liquor or water from the nozzles 76 not only wash out the tar, causing it to flow into the tar-tank D,
,but also serves to prevent soot, lampblack,
and other suspended matter from settling and mixing with the tar. The soot and lampblack will thus becaused to float near the surface and overflow into the skimmer H, from which it passes off with the excess of ammoniacal liquor and water through the discharge-pipe R into a separating-tank. (Not here shown.) In the settling-tank or separator the suspended matteris given time and space to settle or deposit, and the water, practically freed from suspended matter, is return ed to the hydraulic main by means of a pump, either directly or through an elevated reservoir placed at a suitable height to discharge the water through the nozzle is under sufiicient pressure to give a good washing and scouring effect in the main By pumping the ammoniacal liquor over into the hydraulic main any volatile hy drocarbon oils contained in such liquor will be vaporizedand thusadd to the illuminating power of the gas.
i In starting the use of the apparatus constructed as above describedthe valve 0 in thedischarge-pipe L is closed and the tank Dis filled with water or other'suitable liquor up to the level of the overflow of the skimmer H in thehydraulic main. The valve 0 is kept closed until the tank D has become'filled to and discharged through the skimming device H and its outlet-pipe'R. When sufficient tar has accumulated in the tank D, the valve 0 in pipe L will be opened, thus permitting the liquids contained in the tank to adjust themselves to their natural levels according to l theirpeculiar specific gravities.
This apparatus has provensimple and effective and has given satisfactory and valuable results in practical operation.
