Summary of the invention:

A kind of energy-saving electrolyzer that has electrolysis cycle discrepancy isolation channel; The groove internal polar plate is cascaded structure each other; It is characterized in that: 1, circular electrolyte is set respectively goes into liquid isolation channel and circular electrolyte fluid isolation channel, electrolytic solution is gone into liquid isolation channel, electrolyzer and circular electrolyte fluid isolation channel through circular electrolyte respectively and is realized circulation.2,1. pole plate isolates electrolytic solution notch effective combination the 2. through isolating to install with pole plate relatively, and the edge of pole plate places and isolates among the notch.3, go into liquid isolation channel equal liquid hole along the setting of pole plate vertical direction, fluid isolation channel fluid hole is positioned at the bottom.4, electrolyzer part bottom tilts to the liquid outlet end.

The reduction of system power has greatly reduced the use of metallic conduction bus; Do not conduct electricity crossbeam and conductive contact, practiced thrift a large amount of non-ferrous metals yet.Compare with traditional electrolyzer, the consumption of equipment non-ferrous metal reduces more than 80%, and the production of units power consumption reduces 5%-10%.Because system power is low, helps adopting energy-saving high-frequency electrolysis power supply.

Characteristics of the present invention:

1, the groove internal polar plate changes series model into by parallel connection, has improved single bath voltage, has reduced system power, and reduced the circuit metallic conductor because the voltage loss that big electric current causes, and power consumption is low, and the non-ferrous metal usage quantity is low.

2, utilize electrolytic solution as the power transmission carrier, do not have metallic conduction crossbeam conductive contact, practiced thrift metallic conductor, reduced line drop.The total system circuit is not flexible coupling in the road, has reduced the incidence of fault, has improved production efficiency.

3, be provided with circulation of elecrolyte and go into liquid isolation channel and fluid isolation channel, it is minimum that the electric leakage that circulation of elecrolyte is caused reaches.

4, do not play the current delivery effect owing to the pole plate body does not recur under going up, pole plate can be done thinlyyer.Do not had pole plate by conducting electricity crossbeam to the pressure drop the liquid level, power consumption reduces.

5, owing to take groove internal polar plate series model, electric current descends, and the pole plate distribution of current is even, helps the use of ultra-large type pole plate.

6, the electrolyzer top crown is isolated the use that notch is installed, and the installation of pole plate and replacing are very easy to.

Embodiment:

The present invention's branch circulation of elecrolyte is gone into liquid isolation channel, electrolyzer, circulation of elecrolyte fluid isolation channel three parts.Two pole plates of electrolyzer end are connected with power supply respectively.Circular electrolyte gets into from the inlet of going into the liquid isolation channel, gets into electrolyzer through inlet opening and equal liquid hole, again through fluid hole, flows out from the circular electrolyte riser.

Be provided with pole plate in electrolyzer two sides, top and bottom and isolate installation notch (Fig. 6), pole plate places pole plate to isolate and installs among the notch.

When this device is used for the electrolytic etching of metal refining; Directly will slightly refine positive plate and place pole plate to isolate among the installation notch, the thing of finishing metal of generation is covered on the anode metal on opposite, when electrolysis finishes; Take out and remove remaining anode crude metal, obtain the pure metal body of electrorefining.During the electrolysis powder body material; Place pole plate isolate to install among the notch insoluble anode plate; Electrolysis gained powder body material is covered on the positive plate, owing to do not have the conduction bracing of parallelly connected electrolytic pole board to stop on the cell body, and after powder body material very easily scrapes off; Outside the drain tank of bottom, thereby realize continuously uninterrupted production.During water electrolytic gas, then adopt compound polar plate, very easily gas collector is set, collect and generate gas from cell body top.

It is to adopt plate body material that the cell body of this device is made a kind of, like making such as plastic plate, glass epoxies; Another kind is to adopt the concrete polymer to make, and pole plate isolation this moment is installed notch and after building, installed.Electrolyzer must not adopt the steel plastic synthetic material to make.

Because adopt the pole plate series system, Faradaic current is less, but voltage is higher, consider safety factors, general electrolysis voltage design is about 100v, and electric current should be selected the high-frequency electrolysis power supply for use, to improve power-efficient basically below 1000A as far as possible.Next electrolysis monomer of generalized case just can constitute an electrolysis system.

Because single groove electrolysis voltage is high, the staff to prevent to get an electric shock.During electric tank working, avoid the staff directly to contact conductiving metal part and electrolytic solution.Adopt insulating bodies to scrape and get powder body material and groove face pollutent; When electrorefining finishes, can carry out other operations after having a power failure.The electrolytic solution storing unit will adopt non-conductive material making such as plastics.
