The graphite cathode electrolytic bath can solve the problems of corrosion and frequent maintenance of the cathode of the electrolytic bath, completely eliminate the lead pollution existing in the production process, prolong the maintenance cycle of the electrolytic bath, strengthen the production capacity of the device and reduce the labor intensity of workers.
Description
Technical field
The utility model relates to a kind of graphite cathode electrolyzer, particularly a kind of graphite cathode electrolyzer that is used for ammonium sulfate electrolysis production ammonium persulphate.
Background technology
The production ammonium persulphate method of domestic mature technology is generally to adopt the electrolyzer of lead electrode to produce persulphate at present.The negative electrode of electrolyzer is arranged basket electrode for the no end that the metal stereotype constitutes, and row's anode is installed in each row's basket is formed an electrolysis cells, and the industriallization that an electrolyzer is used for ammonium persulphate is formed in common every 4-6 and the unit that is equipped with cooling water coil.Owing to plumbous self characteristics, can constantly be corroded is dissolved in ammonium sulfate electrolytic solution to lead electrode under acidic conditions in process of production.Owing to this reason, there is following problem in current lead electrode electrolyzer:
One, under the acidic conditions, lead electrode constantly dissolves, and lead salt gets in the electrolytic solution, causes the plumbous Lead contamination that gets in the product thereby cause product.
Two, the lead electrode use because of corrosion needs to take out maintenance, caused the service worker work of production unit negative how very high after 6-8 month usually.
Three, the pollutent that produces in service worker and lead electrode and the lead electrode maintenance process contacts, and Plant personnel is had suck the plumbous risk of higher concentration.
Four, the lead that is dissolved in the production process in the electrolytic solution constantly is deposited in the plumbous mud of formation in the electrolyzer, and this is the great heavy metal contaminants of a kind of environmental hazard, and every platform trough is annual to produce up to a hundred kilograms.Need this environmental exposure material is disposed, it is very high to dispose difficulty and risk.
Five, because of the metal reactivity of lead higher (coming the front of hydrogen), and in electrolytic process, there is hydrogen to separate out, so has hydrogen-evolution overpotential to exist on each lead electrode from lead electrode.Though this voltage several volts at not high only zero point, Faradaic current reach thousands of amperes, make product consuming electric power per ton thus and reach 1700-1900 kilowatt-hour product per ton.
The utility model content
The utility model technical problem to be solved provides a kind of; It can solve the corrosion of electric tank cathode and frequent maintenance problem, and can eliminate throughput, the reduction working strength of workers of the Lead contamination that exists in the production process, the maintenance cycle that prolongs electrolyzer, strengthening device fully.
For solveing the technical problem; The utility model provides a kind of graphite cathode electrolyzer that is used for ammonium sulfate electrolysis production ammonium persulphate, it is characterized in that, it comprises negative electrode graphite row, graphite electrode columns, anode cover plate, negative electrode copper bar, anode jack; Negative electrode graphite row, graphite electrode columns are formed the graphite cathode framework; The negative electrode copper bar links to each other with the head of graphite electrode columns, and the anode cover plate is fixed in the top of graphite cathode framework, has one group of anode jack on the anode cover plate accordingly.
The positive progressive effect of the utility model is: the utility model can solve the corrosion of electric tank cathode and frequent maintenance problem, and can eliminate throughput, the reduction working strength of workers of the Lead contamination that exists in the production process, the maintenance cycle that prolongs electrolyzer, strengthening device fully.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1; The graphite cathode electrolyzer that the utility model is used for ammonium sulfate electrolysis production ammonium persulphate comprises negative electrode graphite row 1, graphite electrode columns 2, anode cover plate 3, negative electrode copper bar 4, anode jack 5; Negative electrode graphite row 1, graphite electrode columns 2 are formed the graphite cathode framework; Negative electrode copper bar 4 links to each other with the head of graphite electrode columns 2, and anode cover plate 3 is fixed in the top of graphite cathode framework, has one group of anode jack 5 on the anode cover plate 3 accordingly.The anode cover plate is used for fixing anode and forms fluid-tight, and the anode jack is used to insert anodal closure, forms the electrolysis loop.
When normal the use, immersion filled in the pot shell of certain density sulfuric acid/ammonium sulfate mixed liquor after the anode cover plate was fixed on the graphite cathode framework; Then with the negative electrode copper bar be negative pole, the anode that is inserted in the anode jack is positive pole, add suitable voltage and control certain electric current and carry out electrolysis.Electric current is pooled to the negative electrode copper bar through the electrolytic solution in anode, the pot shell, negative electrode graphite row and graphite electrode columns successively during electrolysis, forms the loop of Faradaic current.Following electrochemical reaction takes place on anode and cathode simultaneously:
Hydrogen ion obtains electronics on negative electrode graphite row and graphite post, and formation hydrogen, reaction formula are as shown in the formula (1):
2H
++ 2e==H
2Formula (1)
The hydrogen that forms is collected in interior back emptying of fluid-tight or recovery that anode upper cover plate and electrolytic solution are formed.
On anode, sulfate ion loses electronics, forms the persulfate ion, and reaction formula is as shown in the formula (2):
2SO
4 2--2e==S
2O
8 2-Formula (2)
The persulfate ion that forms is dissolved in the electrolytic solution.With the electrolytic solution evaporative crystallization, just obtain product ammonium persulphate crystal.
The distinctive feature of the utility model has been to use the lead electrode that the graphite material of no liberation of hydrogen electromotive force has substituted has the liberation of hydrogen electromotive force; And the geometrical dimension and the shape of Graphite Electrodes have been taken all factors into consideration; Make the current path between negative and positive shorten as far as possible and reduce electrolysis voltage and fall, reached good energy-saving effect thus.Simultaneously thoroughly eliminated the Lead contamination in the production process replacing in the plumbous improvement with graphite, from and reached good environment protecting.In addition, because the corrosion of the anti-vitriolic of graphite, be immersed in that prolong significantly than lead electrode the work-ing life of cathode material in the electrolytic solution, this makes maintenance cycle, maintenance cost and the working strength of workers of electrolyzer that the benefit that descends significantly arranged.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
