of petroleum oils and may be withdrawn from the refining stills in liquid form at approximately 750 F. In order conveniently to handle this material it is necessary to cool, congeal and break it up into relatively'small particles. It is among the objects of the present invention to provide an improved method of and a continuously operating apparatu for disintegrating hot liquid petroleum coke or the like and at the same time cooling and congealing it in small particles. A further object of the invention is the provision of apparatus for cooling, disintegrating and congealing liquid petroleum coke or the like and removing the congealed particles to a place of disposal which apparatus is substantially automatic in operation and very economical of cooling water.

The above and other objects of my invention will appear from the following description of my preferred procedure and of apparatus adapted to carry out the steps of my process, reference being had to the accompanying drawings, in which 1 Figure 1 is a diagrammatic side elevational view of my improved disintegrator together with means for conveying the broken up material to a separating tank orvhopper and returning the water used in the conveying conduit to the disintegrating jets.

Figure 2 is a plan view of the cooling and disintegrating unit shown in Figure 1.

Figure 3 is a vertical cross-sectional view taken substantially on line 3-3 of Figure 2.

Figure 4 is a vertical cross-sectional'view taken substantially on line 4-4 of Figure 2.

Figure 5 is a fragmentary view taken on line 5-5 of Figure 3 illustrating the arrangementof disintegrating jets.

Referring now to the drawings, the hot liquid coke, or other material which is to be disintegrated and cooled such a slag for example, is conveyed from any suitable source through the pipe I to the tank 2 01' the cooling and disintegrating unit. As is best seen in Figure 3, the pipe I discharges the hot fluid in a solid stream downwardly into the tank 2. Surrounding the outlet 3 of the pipe I is an annular chamber 4 which is connected to the water jet supply pipe 5. A plurality of nozzles 6 (see Figs. 3 and 5) are disposed around the outlet 3 of the pipe I and are adapted to direct jets of water under high pressure in inwardly converging streams into the mass of hot fluid material being discharged from the pipe I. These high pressure jets from the nozzles 6 break up the discharged liquid coke into small particles and at the same time cool it so that it is at least partially congealed.

The bottom portion of the tank 2 is preferably made in the form of a hopper as indicated at I. This is maintained full of water by means of an automatic float valve which controls the supply of make-up water which enters the tank through the pipe 8. The automatic float valve may be of any suitable form and is diagrammatically illustrated as including a float 9 secured at the lower end of an operating rod III which is connected at its upper end to a link II. The valve stem I2 is connected to the link II which has one end pivotally supported at l3. The valve which shuts 'ofi the supply of makeup water is shown at H.

In operation, when the level of the water in the tank 2 falls the float 9 will drop and the resulting downward movement of the lever II will open thevalve ll permitting water to be discharged into the tank through the pipe 8. As the level rises the float 9 lifts and, when the predetermined proper level is reached, the valve M will be closed. An emergency or safety overflow pipe I5 is provided which extends out of the tank 2 preferably somewhat above the normal water level therein and a vapor outlet pipe i6 is adapted to carry away steam and gases created by the contact of the hot liquid with the water disintegrating and cooling jets.

The jets of water from the nozzles 6 will drip the congealedv coke particles into the body of water in the hopper portion 1 of the tank 2- where the particles will be further cooled and congealed if they have not already been completely congealed by the action of the water jets. A pair of pumps l1 and I8, driven by any suitable means, not shown, are adapted to withdraw the mixture of water and particles of coke from the,

bottom of the hopper 1 through the pipes lsand 20. The pumps l7 .and I8 discharge through outlet pipes 2| and 22 into a common mixture conveying conduit 23 which, as seen in Figure 1.

lated solids from the tank. Thewater which' is separated from the solids in the tank 24 passes out through a pipe 27 into a sump 28. From this sump 28 a pump 29 forces the water through the pipe 5 into the annular chamber 4 around the pipe I and through the nozzles 6 forming jets which impinge upon and disintegrate and cool the hot fluid coke as it is discharged from the outlet 3 of the pipe I. A make-up water supply pipe 30, controlled by a valve 3|, may be provided to add water to the sump 28 when necessary. The supply of make-up water brought to the tank 2 through the pipe 8 and the float controlled valve may come from any suitable source (not shown).

From the above description of a preferred arrangement of my improved apparatus for disintegrating and handling fluid material such as hot liquid coke or the like, it will be seen that the consumption of water used in disintegrating, cooling and conveying is reduced to a minimum. The water which is forced through the nozzles 6 serves to disintegrate and at least partially cool the material being handled as it is discharged from the pipe I. This same water serves to assist in maintaining the water level in the hopper portion 1 of the tank 2 and thus maintain the proper pool or body of water into which the disintegrated material falls and by which it is completely cooled and congealed. This same water also serves as a conveying agent for carrying the congealed material to a place of disposal such as the tank 24 and is then separated from the solids and returned to the system through the nozzles 6. Of course, it will be necessary to add make-up water to the system due to unavoidable losses from the separating tank, etc. If desired the mixture of solids and water conveyed by the pipe 23 may be discharged upon a pile and the drained off water collected and returned to the system in a manner similar to that illustrated and described in my co-pending U, S. patent application, Serial No. 199,371, filed April 1, 1938. By arranging the nozzles 6 so that their streams all converge into the hot fluid being discharged from the pipe I a thorough disintegrating and cooling action is obtained and my system, in addition to being exceedingly economical of water, most effectively breaks up and solidifies the liquid coke or the like and then deposits the particles in a relatively large body of water from which the mixture of water and congealed material may readily be removed by suitable pumps.
