APPARATUS FOR COOLING WASTE WATER.
SPECIFICATION forming part of Letters Patent No. 586,281, dated July 13, 1897. Application filed February 19, 1897. Serial No. 624,194. (No model.)V
T rZZZ 70750777, 7'Ir2 may concern.-
Be it known that I, JOHN E. BECKMAN, a
citizen of the United States, residing at Buf-.
falo, in the county of Erie and State of New .5 York, have invented newand usefullmprovements in Apparatus for Cooling `Waste lVater, of which the following is a specification. This invention has the object to provide means for cooling the waste water of steam lo plants before it is discharged into the sewer or drain, so that the waste water enters the sewer or drain cool, and at the same time to save the water which is employed for cooling the waste water. As now commonly pracx ticed the hot waste water is mixed with cold water before it is discharged into the sewer, wherebyT the waste water is cooled and the harmful results of discharging hot water into the sewer are avoided, but the cold water 2o which is used for cooling is wasted in this method, and as large quantities of cold water are required for this purpose the cost of the wasted cold water is considerable. According to my invention the cold water which is used for cooling thehot waste water and which ab,- sorbs the heat from the waste water is used for feeding the boiler, so that the heat which has been extracted from the waste water is returned to the steam plant. 3o The accompanying drawing represents a sectional elevation of an apparatus whereby my invention can be practiced.
A represents the receiving or expansion tank, which collects the hot waste water from the various pipes a, which receive the hot water from the blow-oit cocks of the steamboiler, the drips of the steam-engine and steam-pumps, and other apparatus in the steam plant, which may be that of an oftice- 4o building, store, or factory. This tank may also receive the exhaust-steam through a pipe Z).
O represents a surface condenser which surmounts the expansion-tank and receives the steam or vapor therefrom through pipes c. These pipes open into the space surrounding the cooling-pipes CZ of the condenser, and the upper portion of this space communicates with a vent-pipe CZ', which opens into the atmosphere, preferably through the roof of the building in which the plant is situated. The
pipes CZ communicate at their-lower ends with the lower waterchamberD of the condenser, and at their upper ends with the upper water-chamber D. p
E represents the hot-water-discharge pipe through which the hot water escapes from the expansion-tank and which connects with the upper end of a cooling-coil F. The latter is arranged in a closed cooling-tank G, and 6o its tail-pipefextends through the lower portion of this tank and leads to a sewer or drain H. A trap h and a fresh-air inlet Z are arranged in the tail-pipe between the coil and the drain. The tank G is provided with a blow-off pipe Z opening into the tail-pipef. An air-inlet valve j is preferably arranged in the hot-water pipe E, leading to the coil F, to admit air to the coil in case a partial vacuum should be formed in the same. The 7o hot-water pipe E is preferably provided with a branch pipe e, through which the water can be discharged from the receiving-tank A into the drain without passing through the cool'- ing-coil, for instance in cleaning the receiving-tank.
K represents the cold-water pipe which leads to the lower portion of the cooling-tank G and through which the water which is used for cooling the hot water is supplied to the 8o tank. The upper portion of this tank is connected with the lower water-chamber D of the condenser by a pipe Z, and the upper water-chamber D' has at its upper end an escapepipe m, through which the hot water escapes therefrom.
The hot water parts with its steam or vapor in the expansion-tank, and the steam or vapor escapes upwardly through the condenser O and is condensed in the same, the con- 9o densed water iiowing back into the expansion-tank through the pipes c. The hot waste water flows from the expansion-tank through the cooling-coil F, and is cooled in the same by the surrounding cold water and discharged 'cool through the tail-pipe into the drain.
The incoming cold water becomes heated in the water-cooling tank G and flows upwardly through the latter and through the pipe Z into the lower portion of the condenser O. The roo water becomes still further heated in the latter in -condensing the vapor or steam and escapes more or less heated from the upper end of this tank through the pipe m. This heated water may now be supplied to the steamboiler after passing it through a feed-water heater of any suitable construction or by pumping it directly into the boiler, or it may be otherwise utilized, as may be preferred. By this means the heat which is contained in the hot waste water and exhaust-steam is extracted before the water is discharged into the sewer and the water is delivered cool,while the water whichreceives such heat is utilized, thereby avoiding the wasting of the water which has been used for coolin g the hot waste water.
I claim as my inventionl. The combination with a receiving-tank which collects the hot waste water and which is provided with an outlet-pipe for the escape of such water, of a surface cooler which is arranged below said outletpipe and which has its upper end connected therewith to receive the hot waste water from said tank, and which is provided with a cold-water supply by which the cooling-water is admitted to the cooler near the lower or discharge end thereof and with an escape for the heated cooling-water at the opposite end, substantially as set forth.
2. The combination with a receiving-tank which collects the hot waste water and which is provided with an outlet-pipe for the escape of such water and above said pipe with an ascending Vapor -escape pipe, of a surface condenser which is arranged above said tank and connected at its lower end with said vapor-escape pipe, and a surface cooler which is arranged below the water-outlet of said ranged below the water-outlet of said tank and which has its upper end connected therewith to receivef the hot water therefrom, a
supply-pipe for admitting the cooling-water to the lower end of said cooler, and a connecting-pipe whereby the partially-heated cooling-water is conducted from the upper end of said cooler to said surface condenser, substantially as set forth.
fitness my hand this 15th day of February, 1897.
JOHN E. BECKMAN.
