FEED-WATER HEATER AND PURI'FIER.
SPECIFICATION forming part of Letters Patent No. 726,243, dated April. I28, 1903.
Application filed June 3, 1901. Serial No. 62,945. (No modeL) To all whom/ it may concern:
Beit known that I, JOSEPH BEHA, a subject of the Emperor of Germany, and-a resident of Thann, Alsace, Germany, have invented certain newand useful Improvements in Feed- Water Heaters and Purifiers, of which the following is a specification.
In the rapid development of motor road-vehicles which has taken place in recent years only carbureted-hydrogen motors have to any extent participated, while the old steam-motor has been discarded for reasons which will be hereinafter explained. With the small dimensions to which the steam-generator for this particular purpose was necessarily restricted it wasimpossible to prevent the generator-pipes and the other parts becoming obstructed in a short time by the separation of sludge and scale. Nevertheless it would be of considerable importance if steam-motors could be adopted instead of the benzin and petrol motors hitherto generally employed,as, on the one hand, its construction is exceedingly simple, so that repairs which may be necessary on the road can be effected without difliculty by riders who have not been instructed in such matters, and, on the other hand, water is to be found everywhere, while it is often difficult to obtain benzin or petroleum. If it were possible to use water taken from any source and to purify the same during the journey, the steam-motor for motor road-vehicles would unquestionably take up and maintain the preeminent position that is due to it.
Now the object of the present invention is to overcome this difficulty, and this I effect by the complete and instantaneous purifica tion of the feed-water during the journey by simultaneously heating, decanting, or drawing off and filtering the same by means of an apparatus which occupies but little space.
The invention is illustrated in the accompanying drawings as applied, by way of example, to a serpollet-motor.
Figure 1 is a vertical section of the steamgenerator arranged on a carriage-frame, the purifying apparatus being situated above the capillary generator-pipes and within the generator-casing. Fig. 2 is a vertical section of the purifying apparatus, taken on the line E F of Fig. 4. Fig. 3 is a front view of the same. Fig. 4 is a horizontal section taken on the line A B of Fig. 2. Fig. 5 is a vertical section taken on the line C D of Fig. 4.
According to my invention, the purifying apparatus consists, substantially, as will be seen from Figs. 2, 4:, and 5, of a cylindrical ring 1, open at top and bottom, the casing of which is formed by spiral passages 2. This ring, as shown in Fig. 1, is interposed in the feed-water pipe 3 inside the casing 5 and immediately above the generator 4. The spiral passages 2 are of greater sectional area than the feed and discharge pipe 3, so as to retard inside the apparatus the velocity of the feed-water entering the uppermost spiral passage. The feed-pipe 3 is connected with the water-supply by a pipe 6, in which are interposed a safety-valve 7 and a return-valve 8. To the end of the lowest spiral passage of the ring is attached a sludge-collecting pipe 22, the outlet of which is through a pipe 11. At the back of this sludge-collecting pipe is fixed the discharge-pipe 8, which forms, where it is attached to the cylindrical ring, an enlarged chamber 18 for receiving the filter 19. This filter, as will be seen from Fig. 2, consists of a conical -or taper chamber 19, retained in position by means of its flange 21 between the corresponding flanges of the discharge-pipe 3 and chamber 18, the front and back openings of which chamber are provided with grids and a cone 20,fixed at its base, and the object of which is to break up the caked mud driven back in the course of the purification, as will be hereinafter explained.
Prior to starting the motor the valve 7 of the pipe 6 is opened. The water enters through the valve 8 into the pipe 3 and passes through the spiral passages 2 in the cylinder 1 into the capillary pipes 4 of the generator. After the burner 23 has been ignite the water in the generator-pipes is at once vaporized and superheated, so that the motor may be run without delay, the feed-pump at. the same time also coming into operation; The combustiongases flow upward, then pass around and through the purifying-cylinder l and the fiues 9 down into the chimney 10. By reason of the excessively high tempera ture to which the purifying-water is exposed when entering the purifying apparatus its heat is rapidly increased to over 150 centigrade, so that the matters eliminated from the water at this temperature are deposited while the water is flowing slowly through the spiral passages of the purifier and are collected in the sludge-chamber 22. The water then passes through the filter 19, arranged in the enlarged space 18, and there parts With any impurities which may have been carried over with it before entering the generator through the supply-pipe 3.
Owing to the continuous deposit of impurilies in the spiral passages of the purifier, a thorough and instantaneouspurification must be provided for in the sludge-chamber and in the filter. To this end the feed-pipe 3 is furnished below the filter with a T-piece 15, which forms the connection with the motor through the pipe 12. In this pipe is a valve 14, while in the lower end of the pipe 3, just before it enters the generator, a valve 16 and a return-valve 17 are provided. Behind the mud-chamber 22in the sludge-discharge pipe 11 a valve 13 is inserted.
If the valve 16 be closed and the valves 14 and 13 be opened, the pressure of steam from the motor through the pipe 12 forces the filtering medium compressed in the front conical part of the filter onto the cone 20, which is situated in the base, and breaks up and purifies said medium. The expelled sludge enters the sludge-chamber 22 and passes out through the pipe 11 with the impurities already deposited therein. The whole purifying operation requires but a few seconds.
My improved water-purifier may be employed without material alteration with any kind of steanrgeuerator.
Having now particularlydescribed and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In a steam-generator, the combination with the combustion-chamber, of a cylindrical ring arranged in said combustion-chamber and adapted to be heated at its inner and outer surfaces, said ring being interposed in the feed-pipe and havinga helical channel of larger area than that of the feed-pipe, said channel communicating with the steam-generator, a filter interposed in said com m unication, a sludge outlet-pipe from said helical channel and means for supplying feed-water thereto, substantially as described.
2. In combination, the steam-generator with means for supplying heat thereto, the cylindrical ring having a helical sludge-depositing chamber also adapted to be heated by said heating means, means for feeding water to said helical chamber, a sludge-outlet pipe having a suitable stop-cock, a pipe connection from said helical chamber to the steam-generator, a filter in said pipe connection, and means for cleansing said filter, substantially as described.
3. In combination, the steam-generator with means for supplying heat thereto, the sludge-depositing chamber with means for feeding the water thereto, a sludge-outlet from said chamber, a pipe connection between the sludge depositing chambers and the steam-generator, a filter in said communication, a steam-pipe from the steam-generating tubes for passing steam through said filter to cleanse the same, and valves in said pipes, substantially as described.
4. In combination, the steam-generator, a sludge-depositing chamber arranged to receive the feed-water, a pipeleading from said chamber to the steam-generator, a conical filtering-chamber interposed in said pipe connections andcontaining filtering material, a cone embedded in said filtering materialand connections for admitting steam in each of said filtering-chambers to cleanse the filtering material, substantially as described.
5. A feed-water cleaner for steam-generators comprising acylindrical ring interposed in the feed-water pipe, and adapted to be heated by the hotgases, said ring containing a helical channel of larger cross-section than the feed-water pipe, a sludge-collectingcham ber branching off from said helical channel near the end thereof, and a filter located in the feed-water pipe or conduit above the sludgecollecting chamber, substantially as described.
In Witness whereof I have hereunto set my hand in presence of two Witnesses.
