Description
endowed with a rec.tilineal alternating motion which is directed along the longitudinal axis thereof and which is · controlled, for example, "by means of a crank and connecting-rod mechanism or the like.
In point of fact, the industrial development of the method which has just been summarized has led to the discovery that, if the rectilineal alternating motion as initially, contemplated is replaced by a curvilineal alternating motion of each movable electrode, it is thereby made possible, not only to achieve the optimum operating conditions which are a distinctive feature of the Patent Application hereinabove referred-to, but also to improve the practical application of this method to a marked extent.
The utilization of the above-mentioned curvilineal alternating motion has in fact proved to be particularly advantageous, especially for the following reasons % a) in the casein which alternating current is employed, the alternate utilization of the two current polarities is more readily permitted by a curvilineal alternating motion than by a rectilineal alternating motion; b) curvilineal alternating motion offers a particularly easy solution to the problem of fluid-tightness of the' reaction tank at the level of the mechanism which controls the travel of the movable electrodes.
The present invention therefore has for its object an .improvement which is made in the method described in the above-mentioned Patent Application and which essential- · ly consists in imparting to the movable electrodes a cur which are contemplated in the Patent Application hereinabove referred-to.
In the practical application of the aforesaid improvement, the. curvilineal alternating motion of the system which carries the movable electrodes can be -produced especially by means of a_ pendulum arrangement or by means of an eccentric mechanism.
Forms of execution of each of these' two types of 'drive systems have been illustrated in the accompanying drawings by w.ay of example only and not in any limiting sense. In these drawings s - Fig.. 1 is a diagrammatic cross-section of an apparatus in which the curvilineal alternating motion of the movable electrodes is produced by means of a pendulum; - Fig. 2 is a similar view of an apparatus in which the curvilineal alternating motion of the electrodes is produced by means of an eccentric mechanism.
In the form of embodiment of Fig.1 , the apparatus comprises a reaction tank 1 which is filled with the liquid hydrocarbon to be processed. There are shown at 2 and 2' two stationary electrodes which are disposed in symmetrical relation and penetrate at an oblique angle into the · tank 1 through suitable fluid-tight · packings fitted in the opposite lateral walls of said tank;- the positions of said electrodes can be adjusted longitudinally, for example by means of a rack and pinion mechanism 21-22. Between the stationary electrodes 2, 2' is disposed a moving system consisting of two movable electrodes 3, 3' and suspended from the lower extremity of a pendulum 23, the traverses the wall, of the tank 1 through a packing gland 4. An externally mounted eccentric mechanism 25 which is coupled to the upper extremity of the pendulum 23 by means of a connecting-rod 26 produces and maintains the oscillations of the pendulum with a well-defined and constant amplitude which brings the movable electrodes 3, 3' periodically and alternately, into contact with the corresponding stationary electrode 2 or 2'-.' The operation of the apparatus as thus constituted can easily be regulated so that the essential conditions laid down in the aforesaid Patent Application Ser. N° 17· 135 are complied with. When the apparatus is supplied with alternating current, the frequency of oscillations of the pendulum is synchronised with the frequency of the current employed. When the apparatus is supplied with direct current, the oscillation frequency is established as a function of the desired arcing time. In both cases, the amplitude >of the oscillations is so regulated as to obtain the maximum length of arc which is compatible with the terminal voltage and to produce at' the moment of contact of the electrodes a force of impact which is sufficient to effect the cleaning of said electrodes.
As has been stated earlier, the pendular motion as thus carried into effect has an advantage over the rectilineal motion described in the above-mentioned Patent Application in that it permits of substantial simplification of the apparatus when utilizing the two polarities of alternating current, this utilization being obtained in accordance with the form- of embodiment which is illus cal electrodes designed to cooperate with stationary electrodes which are also symmetrical. In order to obtain the same result, the rectilineal displacement of the movable electrodes as effected by means of a conventional crank and connecting-rod mechanism would call for the use of a crankshaft fitted with two oppositely-acting connecting-rods.
Furthermore, the pendular motion referred-to ensures a simplification of the packing glands at the 'point at which the mechanism for controlling the movement of the movable electrodes traverses the tank 1. In fact, in the case of a rectilineal movement, the travel of the electrode-carrier rod is equal to the travel of said electrodes and the packing gland must ensure leak-tightness during said travel. On the contrary, in the case of pendular motion, the packing glands 4 are subjected only to a rotary motion, the amplitude of which can be reduced to a minimum by lengthening to a sufficient extent the arm of the pendulum which carries the movable electrodes.
In the form Of embodiment which is illustrated in fig. 2, the same reference numerals designate the same elements as in fig. 1 and the stationary electrodes 2 and 2*, the position of which can be adjusted as in the previous example by means of a mechanism such as the rack-and-pinion mechanism 21-22, are located symmetrically and coaxially on each side of the reaction tank 1 and traverse the opposite lateral walls thereof. There this case of a horizontal rod 27 which carries at its extremities the 'movable electrodes 3 and 3'. The said moving system is ' controlled in dependence on two eccentrics 28, 28' by means of spindles 29, 29*. One of the two eccentrics is driven in dotation from a motor (not-shown in the drawings) which is located outside the tank 1 and which drives the shaft of said eccentric whilst the other eccentric is mounted to rotate freely and designed to maintain the moving system 27 in a position which is always parallel with the common axis of the stationary electrodes 2 and 2*.
In this form of embodiment also, the operation of the apparatus can easily be regulated so that the essential conditions indicated in the above-pentioned Patent Application should be satisfied. When the apparatus is supplied with alternating current, the speed of rotation of the driving eccentric is synchronized with the current frequency^ if the apparatus is supplied with direct current, the speed of rotation is established as a function of the desired arcing time. In both cases, the length of the arc is predetermined by the distance O.ff-center of the spindles 29 and 29'. The advantageous feature which is additionally provided by this second form of e bodi^ ent consists in the' fact that, since the arc describes-a semi-circle, the length of the arc increases to a greater extent than the distance, off-center. Finally, the intensity of impact which is necessa'ry for- the purpose of cleaning the electrodes and which takes place at the moment when each movable electrode comes into contact with the corresponding stationary electrode can easily he regulated by means of the mechanisms 21-22 which serve to position the stationary electrodes*.
The advantages of the · eccentric .device which has been described in the foregoing. are ' the- same as those '' of the pendulum system described earlier, namely™ sim- fication of the apparatus when utilizing the two polarities of alternating current and simplification of the solution to the problem of fluid-tightne'ss" at the level of the mechanism 'which controls the movement of the movable electrodes. ·
