Description

Forced circulation type hydrogen oxygen generator

The utility model relates to oxyhydrogen generator, more specifically to the brine electrolysis oxyhydrogen generator, is specially adapted to gas welding, cutting mill comprises: with the electrolysis tank of rectifier power source, cathode-anode plate and containment member and transport pipe.

The brine electrolysis oxyhydrogen generator of this routine, because electrolytic solution--be in basic relative immobilized state between water and pole plate, so the big calorimetric that produces when electrolysis is difficult for distributing, the hydrogen-oxygen micro-bubble that electrolysis simultaneously produces is trapped between the pole plate, just float after becoming air pocket, thereby cause the big efficient of resistance very low.In order to address this problem, generally all be the volume of electrolyzer do very big, between every groove and leave very big space and lower the temperature so that form natural ventilation; In addition, again because pole plate is big and quantity is few, so can only adopt the power supply of low-voltage and high-current, this makes all corresponding increase with cost of volume of rectifying device again, therefore the above-mentioned synergetic effect of factor makes that prior oxyhydrogen producer volume is very huge, the cost costliness, current density is but very low, and then makes manufacturing, application, transportation and maintenance very inconvenient.

The purpose of this utility model is to propose a kind of improved forced cyclic type brine electrolysis oxyhydrogen generator for this reason, it can overcome the defective that exists in the prior art, that is: obviously improve electrolytic reaction, shorten the residence time of hydrogen-oxygen bubble greatly, thereby improve the current density and the efficient of electrolyzer.Moreover, by reasonable arrangement the volume of electrolyzer and power supply and entire equipment is reduced, cost reduces, and makes transportation and maintenance also than being easier to simultaneously.In addition, electric current is adjustable, starts and uses very convenient.

For achieving the above object, the utility model spy takes following measure: a common columnar electrolysis tank is set, at least one group of (but general array) electrode group that primary circle is capable settled in the inside, every group comprises a positive plate and a negative plate, positive pole in the two-plate of outermost end, a negative pole, be series system, in the upper semi-circle of each pole plate and lower half circle zone, a through hole is set at least, to constitute a upper channel and a lower channel, be that the upper channel position of counter electrode plate is provided with a pipeline and passes to a separator and irritate on an end top of electrolyzer, bottom from this separator connects the import that a pipeline is connected to a fluid pressurized pump again, is on the position of counter electrode plate lower channel from the other end bottom that pipeline of supercharging pump outlet connection passes to electrolyzer again.

Preferred version of the utility model is, connects a scatterer by pipe connecting piece between electrolyzer and gas-liquid separator, and for example common coil-type radiator is so that steam is condensed into water.

Another preferred version of the utility model is an electric fan to be set facing to scatterer air blast cooling.

Another preferred version of the utility model be rectifier cell that rectification is used such as heavy-duty diode and scatterer be placed in fan electromotor around, promptly be in the air inlet duct of fan, like this, can cool off rectifier cell again by cooling radiator, reasonably utilize the space again.

Another preferred version of the utility model is that the upper and lower through hole on the battery lead plate is one and is circular hole.

Another preferred version of the utility model is that the upper and lower through hole in the battery lead plate is the hole of a long strip shape, on one side it is a straight line, the other side is a circular arc line, and shape is as half willow leaf, and the circular arc limit is positioned at the radial position away from the pole plate center simultaneously.

Another preferred version of the present utility model is that two end pole plates at least one end pole plate in addition that will connect positive-negative power passes to an end of switch connection pole plate, and when switch connection, then resistance reduces, thereby Faradaic current increases.

Another preferred version of the present utility model is that two end pole plates several pole plates in addition that will connect positive-negative power connect or cross connection successively by switch, then two pole plate short circuits when a switch connection, then three pole plate short circuits during two switch connections, and the like, thereby realize different Faradaic current control.

By a specific embodiment in the accompanying drawing, describe the utility model in detail below.

Fig. 1 is the utility model forced cyclic type brine electrolysis oxyhydrogen generator structural representation;

Fig. 2 is a utility model electrolyzer synoptic diagram;

Fig. 3 is the schematic cross-section of Fig. 2 A-A line;

Fig. 4 is brine electrolysis and a knallgas pump circulation flow schematic diagram in the electrolyzer;

Fig. 5 is the utility model Faradaic current control synoptic diagram.

Referring to accompanying drawing, Fig. 1 is the utility model structural representation, and these parts can be contained in the housing, when using as the gas mixture source of the gas as it, also can be used as big parts and is contained on other device.On oxyhydrogen welding machine or gas cutting machine, this seldom states for the known technology event.Obviously, numbering 1 expression electrolyzer is overall among Fig. 1, it can be by steel ring 1-1, asbestos rubber pad 1～2 and pole plate 1-3 constitute, separate with sealing-ring between steel ring and pole plate, then with bolt with some steel rings, pole plate and sealing-ring series connection tension but this moment bolt structured material guarantee to insulate between pole plate, to guarantee that electric current between pole plate is only by passing through in the electrolytic solution.2 expression topping-up pumps, 3 is gas-liquid separator, and 4 is fan electromotor, and 5 are radiating pipe (being generally serpentine tube), and 6 is fan, and 7 is pipeline, and 8 is pipeline, and 9 is pipeline, 10 is pipeline.

From Fig. 2 and Fig. 3 as can be seen, on each pole plate, be equipped with two hole 11-2,11-1, this electrolyzer correspondingly is a round shape, 11-1 hole on each pole plate all places the Lower Half of pole plate, and constitute an electrolytic solution current downflow pipeline, 11-2 hole on each pole plate places the first half of pole plate and forms flow passage on the gas mixture, so on the lower channel position that the Lower Half that the outlet of the topping-up pump 2 of pump circulation should be connected to electrolyzer one end promptly forms corresponding to pole plate top and the bottom through hole 11-1, and the inlet duct of topping-up pump 2 should be connected to the bottom (being that horizontal plane is with upper/lower positions) of gas-liquid separator 3, and the outlet pipe of knallgas should be connected in the channel position that upward flows that the first half of the electrolyzer the other end promptly constitutes corresponding to through hole 11-2 on the pole plate.

When Fig. 4 represents pump circulation brine electrolysis liquid, the synoptic diagram on water liquid mobile (bottom) and the mobile top of knallgas, A is for injecting brine electrolysis, B is that mixture flows out, from experiment and observation proof, mobility status obviously improves electrolytic efficiency shown in arrow in scheming.

The utility model principle of work is: the electrolytic solution in the airtight electrolyzer (water), behind pole plate feeding direct current, water just decomposites oxyhydrogen on respective electrode plate, because the light just rising of proportion accumulates in top.In addition, effect by pump 2, bottom water hydraulic in the gas-liquid separator is gone in the electrolyzer 1, and upper part of the electrolytic cell knallgas and some steam also have portion water to be admitted to scatterer 5, pass through the ventilation radiating and cooling of fan 6 again, then, gas mixture that these are cooled and water of condensation are admitted to gas-liquid separator 3, like this, top is gas mixture, and the bottom is a brine electrolysis liquid, because the effect of pump 2, the brine electrolysis liquid of bottom can continue to enter electrolyzer again and be able to recycle, has regulated the temperature of electrolyzer electrolyte inside simultaneously.

Fig. 5 represents to control the synoptic diagram of Faradaic current, if pole plate 1-3-1,1-3-2,1-3-3 are connected in turn by switch, the intensity of may command Faradaic current, principle is, as with pole plate 1-3-1 and 1-3-2 switch connection, then two-plate short circuit, electric current increases so resistance reduces then, both can also can intersect successively for method of attachment, can be selected by the user.In like manner, with above-mentioned three pole plate short circuit makings, then resistance is littler, and electric current is bigger.Adopt this method, just can realize the control of electric current at an easy rate, thus very favourable to the starting of machine, especially in the winter time.

Concrete proof by above-mentioned example as can be seen, the utility model advantage is remarkable, volume and weight reduces greatly, electrolytic efficiency has but greatly improved, can directly adopt industry or civilian power supply 380V, 220V in addition,, consider from integral body although increased objects such as pump, scatterer, the utility model has realized that volume is little, in light weight, cost is low, easy to manufacture, transportation and easy to use, efficient height, advantages such as electric current is adjustable, thus make the oxyhydrogen generator technology reach a new level.
