Abstract

The utility model relates to a simulated industry vertical diaphragm salt water electrolytic tank used for teaching, which is composed of an H2 collecting tube, a storage tank, a Cl 2 escape tube, an anode connection post, a salt water dropping tube, a cathode connection post, a graphite sheet, an asbestos cloth sheet, a copper sheet, an alkali overflow tube and a waste liquid discharging tube, wherein, a frame is made of colorless organic glass sheets or other similar transparent materials; the graphite sheet is used as the anode; the copper sheet is used as the cathode; the asbestos cloth sheet is used as a diaphragm to separate the graphite sheet from the copper sheet; thereby, the vertical diaphragm salt water electrolytic tank with a cathode chamber and an anode chamber is produced. The utility model has the advantages of obvious and lucid electrolytic phenomenon, no generated pollution, and safety.

Description

Vertical diaphragm salt water electrolytic cell

The utility model relates to the salt solution electrolyzer, relates in particular to the vertical barrier film salt solution electrolyzer of using as instruments used for education of simulation industry.

Electrolytic saltwater experimental installation and industrial vertical diaphragm sell difference that teaching is at present used are big, and the experimental installation visibility is little, are difficult to collect check H ₂, be difficult to absorb unnecessary Cl ₂, though some improvement projects are arranged in recent years, but still can not in the demonstration electrolytic saltwater, the structure and the production process of industrial vertical diaphragm sell be described, and mostly need many instruments to assemble temporarily, troublesome poeration, inconvenience is reused.

The objective of the invention is to, overcome the deficiencies in the prior art part, provide a kind of simple and reasonable, and can not cause environmental pollution and operator be caused the vertical barrier film salt solution electrolyzer of murder by poisoning.

Vertical barrier film salt solution electrolyzer described in the utility model, adopt the woven asbesto sheet to make barrier film, make anode, make negative electrode with copper sheet with graphite flake, with colourless poly (methyl methacrylate) plate or other easily the colourless transparent material of processing make framework, make and have cathode compartment, the anolyte compartment, add stationary tank, Cl ₂Ease pipe, collection H ₂The vertical barrier film salt solution electrolyzer of conduit, the alkali conduit that overflows.

Use vertical barrier film salt solution electrolyzer described in the utility model to carry out education experiment, visual and understandable.This vertical barrier film salt solution electrolyzer can be continuously, reuse, bath voltage requires low, the general student's power supply that adopts gets final product, electrolytic speed is fast, phenomenon is obvious, not only can check the various products of negative electrode and anodic, also unnecessary product can be stored, absorbs, avoid to the teachers and students' that participate in the experiment murder by poisoning and to the pollution of environment.

Accompanying drawing is the structural representation that meets the utility model theme.

Referring now to accompanying drawing, be described as follows in conjunction with example:

Vertical barrier film salt solution electrolyzer described in the utility model is to design according to the structure of the vertical diaphragm sell of industry and the process of industrial electrolysis salt solution.With reference to accompanying drawing 1, get one thick 4 to 7 millimeters, wide 20 to 40 millimeters, long 70 to 100 millimeters hilt shape graphite flake (7), the two sides polishes with emery cloth, boring; Cut one with the onesize copper sheet (9) of graphite flake (7), boring; Cut 1 to 3 woven asbesto sheet (8) that is slightly larger than copper sheet (9); Get some poly (methyl methacrylate) plates, stick into the uncovered groove long 30 to 50 millimeters, high 70 to 100 millimeters, that inner width is identical with graphite flake (7) with chloroform synthetic glass solution as tackiness agent, graphite flake (7), woven asbesto sheet (8) and copper sheet (9) arranged successively stand in the groove, be stained with the plexiglass cover that has salt solution dropping hole pipe (5), be formed with woven asbesto sheet (8) and do membranous cathode compartment and anolyte compartment.Be connected to cathode terminal (6) on the cathode compartment, be connected to anode terminal (4) in the anolyte compartment.Above the anolyte compartment, hole, and a sticking Cl ₂Ease pipe (3).Stick into a storagetank (2) with synthetic glass again, in order to add storage salt solution and inspection storage Cl ₂Drill with ferrule one hole on cathode compartment, a sticking synthetic glass collection H ₂Conduit (1) is in order to collect H ₂Drill with ferrule one hole under cathode compartment is stained with the alkali pipe (10) that overflows.

With reference to accompanying drawing 2 and accompanying drawing 3, draft the B scheme and the C scheme of vertical barrier film salt solution electrolyzer described in the utility model.Get thick 5 to 7 millimeters, wide 40 to 60 millimeters, long 70 to 120 millimeters some of graphite flakes (7), the two sides coated abrasive working is holed; Get wide 40 to 60 millimeters, some of long 80 to 130 millimeters copper sheets (9), boring; Get some of woven asbesto sheets (8) that are slightly larger than copper sheet (9); Stick into square tube with poly (methyl methacrylate) plate, on the poly (methyl methacrylate) plate therein H is housed ₂Escape orifice is fixed on copper sheet (9) and woven asbesto sheet (8) on the interior position of square tube together, passes through H ₂Escape orifice is drawn lead.Use greater than the poly (methyl methacrylate) plate of square tube mouth and do the end, anchor stone ink sheet (7) is drawn lead on the base plate, has bored alkaline stream and has portalled, and is stained with the alkali pipe (10) that overflows, and promptly use as discharging of waste liquid pipe (11) lower end of the alkali pipe (10) that overflows.The end, adhered on the square tube, can certainly be screwed on the square tube.Sticking into down with synthetic glass is terrace with edge, on have salt solution to drip hole pipe (5) and Cl ₂The storagetank (2) of ease pipe (3) is bonded to storagetank (2) on the square tube, in order to add storage salt solution and inspection and to store Cl ₂At H ₂A sticking collection H on the escape orifice ₂Conduit (6).

Employing synthetic glass described in the utility model is not to do such restriction as making material, and it is good to adopt other colourless transparent plasticss to make material, makes the vertical barrier film salt solution electrolyzer light transmission of producing good, so that experimental observation.
