Abstract
The utility model relates to a three-dimensional electrolyzer with back flushing devices, belonging to the technical field of sewage disposal. The electrolyzer comprises an electrolytic tank and a sewage pool, wherein electrolytic bars are installed in the electrolytic tank. The electrolyzer is characterized in that a compressed air connector is arranged on the side wall on the lower part of the electrolytic tank; the bottom of the electrolytic tank is communicated with the sewage pool via a pipeline; a sewage delivery pump is installed on the pipeline between the electrolytic tank and the sewage pool; a rotor flow meter is installed on a pipeline between the sewage delivery pump and the electrolytic tank; a delivery pipeline is arranged on the side wall on the upper part of the electrolytic tank; the output end of the delivery pipeline is communicated with an acidolysis tank; a back flushing mother liquor tank is connected at the top end of the electrolytic tank via a pipeline; and a back flushing centrifugal pump is installed on a pipeline between the back flushing mother liquor tank and the electrolytic tank. The electrolyzer has the beneficial effects that the electrolyzer has a simple structure and is convenient to operate; and the electrolytic tank is arranged between the sewage pool and the acidolysis tank, thus effectively ensuring that the COD (chemical oxygen demand) concentration of the production sewage is lower than 100mg/L.
Description
Technical field
The utility model relates to a kind of three-dimensional electrolysis device that has back flushing, belongs to technical field of sewage.Background technology
Usually when process for producing sewage, be directly sewage to be entered the acidolysis groove to handle, the sewage that adopts this method to handle is not easy up to standard, and the COD of sewage concentration of general discharging is higher than 100mg/L, rings the discharging of production waste from face.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of three-dimensional electrolysis device that has back flushing is provided, and it is simple in structure, has guaranteed that the COD concentration of production waste is lower than 100mg/L.
The three-dimensional electrolysis device that has back flushing described in the utility model, comprise electrolytic cell and sewage lagoon, the electrolysis rod is installed in the electrolytic cell, it is characterized in that: the electrolytic cell lower sides is provided with the pressurized air interface, electrolytic cell bottom is connected with sewage lagoon by pipeline and communicates, pipeline between electrolytic cell and sewage lagoon is equipped with the sewage transport pump, on the pipeline between sewage transport pump and the electrolytic cell spinner-type flowmeter is installed, the sidewall on electrolytic cell top is provided with line of pipes, the output terminal of line of pipes is connected with the acidolysis groove and communicates, the electrolytic cell top is connected with the back flushing mother liquor tank by pipeline, and the pipeline between back flushing mother liquor tank and electrolytic cell is equipped with the back flushing impeller pump.
The pressurized air interface is set, when feeding pressurized air, can promotes that the electrolysis rod in the electrolytic cell carries out electrolysis treatment to sewage.
During use, start the sewage transport pump, sewage transport to electrolytic cell, is fed pressurized air by the pressurized air interface simultaneously, by the electrolysis rod sewage is carried out electrolysis treatment then, flow to the acidolysis groove from line of pipes at last, carry out acidolysis and handle.When finding that the electrolysis rod has passivation phenomenon, close sewage transport pump and relevant pipeline, start the back flushing impeller pump, the mother liquor in the back flushing mother liquor tank is squeezed in the electrolytic cell, thereby the electrolysis rod is carried out back flushing, reach and recover the active purpose of electrolysis rod.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure, and is easy to operate, owing to be provided with electrolytic cell between sewage lagoon and acidolysis groove, is lower than 100mg/L so guaranteed the COD concentration of production waste effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, electrolytic cell 2, electrolysis rod 3, pressurized air interface 4, spinner-type flowmeter 5, sewage transport pump 6, sewage lagoon 7, acidolysis groove 8, back flushing mother liquor tank 9, back flushing impeller pump.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the three-dimensional electrolysis device that has back flushing, comprise electrolytic cell 1 and sewage lagoon 6, electrolysis rod 2 is installed in the electrolytic cell 1, electrolytic cell 1 lower sides is provided with pressurized air interface 3, electrolytic cell 1 bottom is connected with sewage lagoon 6 by pipeline and communicates, pipeline between electrolytic cell 1 and sewage lagoon 6 is equipped with sewage transport pump 5, on the pipeline between sewage transport pump 5 and the electrolytic cell 1 spinner-type flowmeter 4 is installed, the sidewall on electrolytic cell 1 top is provided with line of pipes, the output terminal of line of pipes is connected with acidolysis groove 7 and communicates, electrolytic cell 1 top is connected with back flushing mother liquor tank 8 by pipeline, and the pipeline between back flushing mother liquor tank 8 and electrolytic cell 1 is equipped with back flushing impeller pump 9.
During use, deposit for the mother liquor that washes 2 passivation of electrolysis rod at back flushing mother liquor tank 8, start sewage transport pump 5, with sewage transport to electrolytic cell 1, feed pressurized air by pressurized air interface 3 simultaneously, carry out electrolysis treatment by 2 pairs of sewage of electrolysis rod then, flow to acidolysis groove 7 from line of pipes at last, carry out acidolysis and handle.By present embodiment, guaranteed that the COD concentration of production waste is lower than 100mg/L.When finding that electrolysis rod 2 has passivation phenomenon, close sewage transport pump 5 and relevant pipeline, start back flushing impeller pump 9, the mother liquor of 8 li of back flushing mother liquor tanks is squeezed in the electrolytic cell 1, thereby electrolysis rod 2 is carried out back flushing, reach the purpose of recovering electrolysis rod 2 activity.
