Abstract
The utility model relates to a frameless container type water electrolytic bath using electrolytic water to generate hydrogen and oxygen. A pole plate group with assembled gas-liquid passages and diaphragms are orderly overlapped and arranged in a cylinder with a flange to compose a small electrolytic chamber and an integral gas-liquid passage, and both ends are closed by flange covers to compose a pressure container type electrolytic bath. The water electrolytic bath has small size, low manufacturing cost, low power consumption and no leakage for medium-pressure running.
Description
The utility model is the electrolyzer that a kind of brine electrolysis is produced hydrogen and oxygen.
Present known water electrolyzer structure is framework and the pole plate group (main pole plate two sides riveted joint porous anode plate and porous cathode plate constitute) that some rivetings have asbestos diaphragm, and the intermediate cryptographic seal washer repeats stack; Or the cotton barrier film of horsestone and seal washer repeat stack between the framework that is welded with the pole plate group, and two ends clamp by tightening screw with end plate and constitute.Its middle frame is manufacture difficulty and the highest parts of cost.
Because above-mentioned structure causes the water electrolyzer leakage point many, can not under higher operating pressure, work, the medium pressure gas that production needs need add compression technology and obtain, and manufacturing cost is high.
The purpose of this utility model provides a kind of water electrolyzer, it can under pressure, work do not leak yet, in light weight, cost is low.
The purpose of this utility model is achieved in that the porous yin, yang pole plate of circular main pole plate both sides constitutes the pole plate group with the tubular rivet riveted joint, unit, circular assembled gas-liquid road is housed on the main pole plate, nested elastic ring on its outer rim, the pole plate group be equipped with the unitary asbestos diaphragm in circular assembled gas-liquid road successively eclipsed place in flanged (FLGD) cylinder body, form some electrolytic chamber and whole gas-liquid road, two ends add the adjustment ring and gasket is clamped with bolt by the cathode and anode end cap, constitute frameless pressurized vessel formula water electrolyzer.
Leak owing to adopt such scheme can guarantee that water electrolyzer works not have under middle pressure operating pressure, but press hydrogen and oxygen in the direct production and descend 20～25% with the relatively weight saving 50% of existing like product, manufacturing cost.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is embodiment external form and sectional view.
Fig. 2 is an embodiment longitudinal section structural map.
Among Fig. 2: unit, A19. spring collar 20. gas-liquid road unit B, 21. gas-liquid road, unit, 1 threaded stud, 2. nut 3. insulating mats, 4. blind flange 5. insulation coverings, 6. flange 7. cylinders, 8. seal washer 9. asbestos diaphragms, 10. porous anode plate 11. tubular rivets, 12. porous cathode plate 13. main pole plates, 14. gasket 15. nuts, 16. studs 17. flanges, 18. gas-liquid road C22. elastic ring 23. is adjusted ring 24. gas-liquid road cells D 25. bolts 26. round nuts.
In Fig. 2: flange (6) and cylinder (7) are formed stack shell.Blind flange (4) connects porous anode plate (10) respectively by round nut (26) and bolt (25) and porous cathode plate (12) constitutes anode end cap and negative electrode end cap.Main group plate (13) constitutes the pole plate group with porous anode plate (10) and porous cathode plate (12) with tubular rivet (11) riveted joint.The nested elastic ring of main pole plate (13) outer rim (22).Spring collar (19) is fixed on three gas-liquid road unit C (21) in two air flues and fluid passage circular hole of main pole plate (13).Spring collar (19) is fixed on three gas-liquid road unit B (20) in two air flues and fluid passage circular hole of asbestos diaphragm (9).Asbestos diaphragm and pole plate group are overlapping successively to be contained in the stack shell, unit, gas-liquid road inserts mutually, constitute whole hydrogen, oxygen road and fluid passage, cathode terminal aerating fluid passage unit A (18) adjusts ring (23), positive terminal aerating fluid passage cells D (24) and adjustment ring (23), add a cover negative electrode end cap and anode end cap respectively, by seal washer (8) sealing, threaded stud (1) nut (2) insulating mat (3) insulation covering (5) is fastenedly connected the composition water electrolyzer with stack shell and cathode and anode end cap between flange (6) and blind flange (4).
All there is a fluid passage circular hole that communicates with each electrolytic chamber all unit, gas-liquid road of forming whole fluid passage, are used for to each electrolytic chamber's conveying electrolyte.All unit, gas-liquid road of forming whole hydrogen, oxygen air flue then have only the unit, gas-liquid road on the hydrogen road that the branch airway circular hole is arranged at the catholyte cell, and the anode electrolysis cell has only the unit, gas-liquid road on the oxygen road that the branch airway circular hole is arranged.
Claims (2)
1. a water electrolyzer has the framework and the pole plate group of asbestos diaphragm by riveting, and the intermediate cryptographic packing repeats stack; Perhaps cotton barrier film of horsestone and gasket repeat stack between the framework that is welded with the pole plate group, two ends constitute by the tightening screw clamping with end plate, it is characterized in that: porous the moon of circular main pole plate both sides, positive plate constitutes the pole plate group with the tubular rivet riveted joint, unit, circular assembled gas-liquid road is housed on the main pole plate, nested elastic ring on the main pole plate outer rim, the pole plate group be equipped with the unitary asbestos diaphragm in circular assembled gas-liquid road successively eclipsed place in flanged (FLGD) cylinder body, form some electrolytic chamber and whole gas, fluid passage, two ends add adjusts ring and gasket by the moon, the positive terminal cover bolt clamps, and constitutes frameless pressurized vessel formula water electrolyzer.
