Description

Portable machine for electrolysis of water for producing hydrogen and oxygen

A kind of light water electrolysis hydrogen producing gas, oxygen machine relate to the molectron of electrolyzer, are specially adapted to hydrogen supply gas, oxygen supply gas or comprehensively use the occasion of hydrogen, oxygen.

Present water electrolysis hydrogen producing gas, oxygen machine are made up of rectifier power source, electrolyzer, filter gas tank and some connecting tubes, rectifier power source links to each other with electrolyzer, with the electrolytic solution in the electrolyzer (aqueous solution of NaOH or KOH) electrolysis, obtain hydrogen, oxygen, and it is separated processing.Such as patent 90226045.6 the top of the insulation tank frame between each little tank room pole plate of formation electrolyzer have two ducts, the bottom has a duct.Two ducts, top link with hydrogen, oxygen effuser respectively, effuser links to each other with the filter gas tank, obviously two effusers and each the little tank room on the insulation tank frame links, it is very inconvenient to make, connect, cost is higher, the more important thing is that so many outside connections reduce the safety coefficient of this device greatly; The duct that open the bottom links by a passage and filter gas tank, and this passage will link with each little tank room equally, has above-mentioned shortcoming equally.And be the arc baffle plate of one and be contained in the barrier film that is bumped into the insulation tank frame on the steel loop with the insulation tank frame, originally be the effect of separating hydrogen, oxygen, but is gas-pervious owing to make membranous nylon when drying, so be easy to cause hydrogen, oxygen mix, form explosion hazard gases, the security of equipment is reduced, and its manufacturing and very trouble is installed also.

The purpose of this utility model provide a kind of safe and reliable, make novel water electrolysis hydrogen producing gas, oxygen machine simple, with low cost.

The utility model is by rectifier power source, electrolyzer, filter gas tank and plurality of conduits constitute, rectifier power source provides direct current to electrolyzer, electrolyzer is made up of some little tank rooms, little tank room comprises pole plate, gasket, the insulation tank frame, there is hydrogen the electrolyzer outside, oxygen outlet, hydrogen, oxygen outlet links with the filter gas tank, filter gas tank bottom is provided with outlet and links with electrolyzer fluid infusion mouth, the filter gas tank also is provided with hydrogen, oxygen outlet, insulation tank frame middle part is provided with a dividing plate, this dividing plate is separated into chamber, the left and right sides with little tank room, and the space that electrolytic solution can be passed through is left with the insulation tank frame in the dividing plate below; Upper part of the electrolytic cell has two independently passages, communicates with little tank room one side room separately, leads to the electrolyzer outside, forms hydrogen, oxygen outlet; The pole plate below has the hole that electrolytic solution is passed through.

In electrolyzer inside, hydrogen that little tank room two side rooms produce separately and oxygen arrive hydrogen, oxygen outlet along upper part of the electrolytic cell passage separately like this; The space of the hole of pole plate below and dividing plate below and insulation tank frame then guarantees the flowable of electrolytic solution in the electrolyzer bottom, and the electrolytic solution in the realization filter gas tank is to the supply of electrolyzer.

From the above, the utility model has been avoided the UNICOM of effuser and each little tank room, formed the autonomous channel of hydrogen, oxygen in electrolyzer inside, and the making of this passage only needs decide hole hyte dress or holes for the last time to finish, though it is convenient, save many joints, reduced cost, reduced the possibility of gas leakage, the fluid infusion system of bottom also is in like manner, and is same safe and simple and with low cost.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 1 is the utility model fundamental diagram.

Accompanying drawing 2 is main pseudosections of the utility model electrolyzer.

Accompanying drawing 3 is front view and side cutaway views of the utility model insulation tank frame.

Accompanying drawing 4 is the utility model pole plate front views.

Accompanying drawing 5 is the utility model gasket front views.

As shown in Figure 1, the utility model to electrolyzer 2 output DCs, makes electrolytic solution (NaOH or the KOH aqueous solution) electrolysis in the electrolyzer 2 by bridge type silicon controlled rectification or 1 rectification of half-wave silicon controlled rectifier, produces hydrogen and oxygen.Hydrogen that is produced and oxygen enter first step filter gas tank 4 by the air outlet of electrolyzer 2 through purifier 3, this filter gas tank has for 4 times flatly and links with electrolyzer fluid infusion mouth, to replenish and to regulate the electrolytic solution in the electrolyzer 2, gas behind first step filter gas is again through second stage filter gas 5, thereby exports after reaching higher purity.

Shown in accompanying drawing 2,3, electrolyzer 2 is made of left plate washer 9, right plate washer 13, some battery lead plates 11, insulation tank frame 10, rubber gasket 12, more than device is combined as a whole by holding bolt 14, and left plate washer 9 is provided with hydrogen, oxygen outlet 7,8, fluid infusion mouth 6, electrode connection seat 27.Each little tank room is by battery lead plate 11 like this, insulation tank frame 10, rubber gasket 12 constitutes, there is a dividing plate 15 at insulation tank frame 10 middle parts in the little tank room, dividing plate 15 is divided into a left side with little tank room, right two side rooms 16,18, electrolyzer 2 tops have two mutual obstructed holes 17,19, two side rooms 16,18 tops respectively have a groove 20,21, separately respectively with hole 17,19 communicate, electrolyzer 2 internal polar plates 11 both sides have just formed two not connected passages like this, avoided the hydrogen and the oxygen mix that are produced, and make delicate structure, be easy to carry, and processing, make also very easy.

Shown in accompanying drawing 4,5, hole the 22,23,24, the 25th, electrolyzer 2 perforates 17,19 are left on pole plate 11 and gasket 12, institute's perforate 26 of pole plate 11 bottoms and dividing plate 15 leave the space with insulation tank frame 10 bottoms, and little tank room is communicated, thereby guarantee the normal supply of electrolytic solution.
