Description

Technical Field

[0001] The utility model relates to the technical field of coking wastewater electrolysis, and specifically relates to a self-cleaning coking wastewater electrolysis device. Background Technique

[0002] The coking wastewater electrolysis device is a device used to treat coking wastewater. Coking wastewater refers to the wastewater containing organic substances such as benzene, phenol, ammonia and heavy metal ions generated during the coke production process. Traditional coking wastewater treatment methods include physical and chemical treatment and biological treatment, but these methods have problems such as low efficiency, high energy consumption and unstable treatment effect.

[0003] The coking wastewater electrolysis device uses electrolysis technology to decompose coking wastewater into hydrogen and oxygen, and at the same time can remove organic substances and heavy metal ions in the wastewater. The electrolysis device usually consists of an electrolytic cell, electrodes, a power supply, etc. The wastewater enters the electrolytic cell after pretreatment, and then by applying an electric current, the organic substances and heavy metal ions in the wastewater are oxidized and reduced to generate gases and precipitates. The gases can be recycled, and the precipitates can be subjected to subsequent treatment.

[0004] However, during the electrolysis process of the coking wastewater electrolysis device, the generated precipitates are easy to adhere to the inside of the coking wastewater electrolysis device. Over time, too many precipitates are easily attached to the inside of the coking wastewater electrolysis device, thus affecting the electrolysis effect of the coking wastewater electrolysis device.

[0005] Based on the above problems, the utility model patent with the application number CN201721491212.X proposes a coking wastewater processor. By directly pressurizing the electrolyte in the electrolytic pretreatment chamber and flowing it into the precipitation pretreatment chamber, the precipitates are carried out during the process of the electrolyte flowing into the precipitation pretreatment chamber, realizing the self-cleaning of the electrolytic pretreatment chamber. However, the above method cannot drive the precipitates that have adhered to the bottom of the electrolytic pretreatment chamber, and there are defects in the self-cleaning effect. Utility Model Content

[0006] The technical problem solved by the utility model is that the existing coking wastewater electrolysis device has a poor self-cleaning effect.

[0007] The technical solution of the utility model is as follows:

[0008] A self-cleaning coking wastewater electrolysis device, comprising:

[0009] A device body, the top of the device body is rotatably connected with an upper cover through a pin shaft, and a rotation module is arranged inside the upper cover;

[0010] Inside the device body, there is an electrolytic cell filled with electrolyte. The bottom of the electrolytic cell is connected to an electrolyte storage tank. Inside the electrolytic cell, there are a longitudinal anode electrode and a cathode electrode inserted into the electrolyte respectively. The tops of the anode electrode and the cathode electrode are connected to a rotation module through fixing blocks respectively, and sediment stirring disks are fixed to the bottoms of the anode electrode and the cathode electrode respectively.

[0011] Further, the rotation module includes a first motor and a second motor respectively penetrating the upper cover. The output end at the bottom of the first motor is connected to the top of the anode electrode, and the output end of the second motor is connected to the top of the cathode electrode.

[0012] Note: The rotation module can drive the sediment stirring disk to rotate through the first motor and the second motor, driving the sediment generated during the electrolysis process in the electrolytic cell to float up within a small range, so as to be taken out of the electrolytic cell by the first water pump, achieving a good self-cleaning effect of the wastewater electrolysis device.

[0013] Further, the rotation module includes a third motor penetrating the upper cover. The output end at the bottom of the third motor is connected to a rotating disk, and the bottom of the rotating disk is fixedly connected to the tops of the anode electrode and the cathode electrode respectively.

[0014] Note: The rotation module can drive the sediment stirring disk to rotate through the third motor, driving the sediment generated during the electrolysis process in the electrolytic cell to float up within a small range, so as to be taken out of the electrolytic cell by the first water pump, achieving a good self-cleaning effect of the wastewater electrolysis device.

[0015] Further, a rotating cover is provided on the electrolyte storage tank.

[0016] Note: The setting of the rotating cover realizes the replenishment and replacement of the electrolyte in the electrolyte storage tank.

[0017] Even further, a side door is provided at the corresponding position outside the device body and the electrolyte storage tank.

[0018] Note: The setting of the side door facilitates the replenishment and replacement of the electrolyte in the electrolyte storage tank.

[0019] The beneficial effects of the present utility model are as follows: The present utility model drives the sediment stirring disk to rotate through the rotation module, so that the sediment adhering to the bottom of the electrolytic cell floats up. Then, the first water pump drives the electrolyte containing sediment to flow out of the electrolytic cell. Finally, the second water pump flows the untreated electrolyte into the electrolytic cell. The coking wastewater electrolysis device achieves a better self-cleaning effect while realizing the replacement of the electrolyte. Description of the Drawings
