Description

Electrolyzer

Technical field

The present invention relates to a kind of electrolyzer.Especially, the present invention relates to a kind of be used for to salt solution swimming pool, watering place etc. similarly retention basin carry out the chlorating electrolyzer.

Background technology

The pond chlorination is necessary for the growth of unwanted bacterium in the anti-sealing.Electrolytic chlorination has become a kind of popular approach that realizes sterilized water.The salt that is arranged in the water in the pond is added in the electrolytic chlorination utilization to, and said pond combines with the electrolyzer that is used to produce chlorine.Said chlorine is discharged in the water, thereby kills any unwanted bacterium and mikrobe.Said process cost efficient is high, the low maintenance and damage to the environment not.

When adopting electrolyzer chlorination tank water, the article of reproducing of this process are hydrogen.Under the normal circumstances, hydrogen is sent in the pond along with the water that flows through electrolyzer and is dissipated in the atmosphere.But if pond pump shuts down, electrolyzer possibly remain in operation, and produces hydrogen.Hydrogen can continue to gather, rather than also discharges into the atmosphere subsequently along with water flows into the pond.Under extreme case,, said hydrogen can set off an explosion if being lighted.

USP (the patent No.: 4861451) described a kind of electrolyzer that is configured to reduce hydrogen explosion possibility in the electrolyzer.Dispose said electrolyzer, so that the import of electrolyzer and outlet are positioned at the electrode below, said electrode is positioned at the electrolyzer body.If hydrogen is in the electrolyzer accumulated, then hydrogen is limited in the electrolyzer, makes water level below said electrode.This makes electrolysis stop, and therefore stops to produce hydrogen.

Electrolyzer shown in the patent 4861451, very effective aspect the amounts of hydrogen of limit electrolysis pond generation.But, because the design of electrolyzer, so there are some inherent defects.When electrolyzer was in level attitude, flowing of water must be through the direction conversion of four 90 degree, so that the restriction to hydrogen in the electrolyzer is provided.This significantly reduces the hydraulic efficiency of pond chlorination system through increasing extra pressure, and it is equivalent to add six meters long pipelines to system in theory.When electrolyzer was in vertical position, the top of chlorination system needed the loop setting in the pond, so that the restriction to hydrogen to be provided once more.This has increased a large amount of extra pipe fittings again.This extra pipe fitting and the change of water (flow) direction need bigger pump usually, so that extract water through chlorination system effectively, make chlorination system expensive more.In addition, along with the change of duct orientation, the common more complicated of drawing water.

Embodiment

Fig. 1 shows the electrolyzer 10 that is used for the chlorination tank water to Fig. 4.Electrolyzer 10 comprises shell 20 and electrode box 30.

Shell 20 is made up of

base

40,50 and two side covers 60 of lid.Lid 50 is through a series of cap bolts 51 and 40 dismountable connections of base, and cap bolt 51 extends around the periphery of lid 50.Bolt hole 41 is positioned at base 40, is used for cap bolt 51 positioned will cover 50 being connected to base 40.Sealing 70 between lid 50 and base 40, with guarantee to cover 50 and base 40 between the junction waterproof.

Side cover 60 be installed in cover 50 and base 40 between the top of junction, to cover cap bolt 51.Side cover 60 has a series of male part 61, and male part 61 is installed in the recessed web member (receiver) 42 that is associated that is positioned on the base 40, so that side cover 60 is fixed to base 40.Front side cap 60 also comprises: conductor casing lid 62 is positioned at the conductor box 52 that covers on 50 to cover.

Import 80 is positioned at an end of base 40, and outlet 90 is positioned at the other end of base 40.Import 80 all has the pipeline connection 100 that is associated so that shell 20 is connected to the pipeline (not shown) that is associated with outlet 90.Import 80 and outlet 90 alignment each other.But, should be realized that according to the design of pond chlorination system, this situation is not necessary.

Fig. 5 illustrates in greater detail electrode box 30 to Fig. 9, and electrode box 30 comprises detachable central module 110, inner support 120, outer support 130 and a series of electrode 140.Detachable central module 110 is made of plastics and through setting treatment, so that be installed in the shell 20, extend to base 40 and cover in 50.The side 111 of detachable central module 110 is through setting treatment, so that near lid 50 and base 40.

Outer support 130 is used to install said a series of electrode 140 with inner support 120.Inner support 120 utilizes the interconnecting piece 121 on inner support 120 internal surfaces 122, with detachable 110 dismountable connections of central module.The outside surface 123 of inner support 120 has a series of inner support recesses 125 that are used for installing electrodes 140.

Outer support 130 also has a series of outer support recesses 131 that are positioned on outer support 130 internal surfaces 132.The top 133 and the bottom 134 of outer support 130 has a plurality of seams 135 that pass outer support 130 tops 133 and bottom 134.This allows water to pass support 130 and process electrode 140.Outer support 130 utilizes interference fit (interference fit) to be connected with inner support 120.The top 133 of outer support 130 is through setting treatment, so that outer support 130 is installed near the internal surface 132 of lid 50.

Each electrode 140 all is tabular and has arc outside 141 and inner edge 142 in said a series of electrode.Electrode 140 is through setting treatment, so that electrode 140 can easily be installed in the crooked shell 20.Should be realized that, the size of electrode 140 and shape be can be provided with and electrode 140 can process by multiple conspicuous for a person skilled in the art material.

Electrode 140 utilizes two conductors 150 (that is, negative electrode or anode) to be electrically connected, and said conductor 150 passes via conductor box 52 and covers 50, and passes the hole that is associated in the electrode 140.Conductor 150 all is carved with screw thread at each end, so that conductor bolt 141 can be placed on arbitrary end of conductor 150, said a series of electrodes 140 are fixed to tightly inner support 120 and outer support 130.Should be realized that electrode 140 is known in the field with being connected to of conductor 150.It should further be appreciated that the electric current of use can change.Such as, can adopt single-stage electric current or twin-stage electric current.

When detachable central module 110 is positioned at shell 20, form spirality channel 160.Spirality channel 160 begins to extend from import 80, passes base 40, passes and covers 50, turns back in the base 40, and extends from exporting 90.Should be realized that according to the particular requirement of the pipeline that is associated of electrolyzer 10 and pond filtering system, the shape and size of spirality channel 160 can change.

In use, water is through import 80 flow channels 160.Water flows through the direction of passage 160 by 43 indications of the arrow on the base 40.Then, water passes base 40, gets into and covers 50, flows around detachable central module 110 arc limits 112.Because the shape of the side 111 of detachable central module 110 and shell 20 couplings are not so water can pass between the side 111 of shell 20 and detachable central module 110.

Then, water passes the seam 135 in the top 133 of outer support 130.Because the top 133 of outer support 130 is near the internal surface of lid 50, water must pass the seam 135 at the top 133 of outer support 130.This has reduced water can the mobile area.Therefore, because water passes seam 135 in the top 133 of outer support 130, through electrode 140, and flow out, so the speed of water increases through the seams in the bottom 134 of outer support 130 135.The increase of this water speed can reduce the gathering of calcium on the electrode 140 potentially.Then, water passes base 40 and flows out from exporting 90.

In use, on level and vertical position, electrolyzer 10 all can use.If pump breaks down, then any excess hydrogen of gathering all can be limited in covering in 50.Any further gathering all can make water level finally drop to electrode below 140, stops to produce dangerous hydrogen.

Spirality channel 160 allows import 80 and outlet 90 alignment.Because water need not pass the turning of any 90 degree, therefore increased hydraulic efficiency.On the contrary, water moves to outlet 90 via spirality channel 160 from import 80, and (patent No.: the electrolyzer 10 that 4861451) illustrates is compared, and spirality channel 160 has increased hydraulic efficiency like USP with traditional.

It should further be appreciated that, under the situation that does not deviate from spirit of the present invention and scope, can carry out various other changes and modification said embodiment.
