Description

Technical Field

[0001] The invention relates to the technical field of electrocatalysis, and in particular to an electrocatalytic hydrogenation reduction device for reducing dyes. Background Art

[0002] Higher requirements are put forward for textile enterprises to adapt to the development of ecological environment and implement corporate social responsibility. Vat dyes are mostly used for dyeing blended fabrics with the same color because of their complete color spectrum, bright colors, excellent light fastness, chlorine fastness and excellent stability. However, due to the structural characteristics of vat dyes themselves, they are insoluble in water, so they cannot be directly used to dye cotton cloth. During use, they must be reduced to the leuco form of the corresponding dye before they can be dyed under alkaline conditions. In most industrial processes, dyes are often chemically reduced with sodium dithionite (suicide powder). In the process of using sodium dithionite reduction, a large amount of sodium dithionite, sulfite, sulfate and toxic sulfide will be produced, which seriously pollutes the environment. Therefore, people have studied catalytic hydrogenation, biological reduction, and new reducing agents to replace sodium dithionite reduction. At present, these three methods cannot meet the needs of industrial production due to harsh reaction conditions, high cost and low reduction efficiency.

[0031] Working principle of the present invention: when the device is used, it is necessary to connect the power supply, and the positive and negative poles of the power supply are connected to the fixed screw 8. The fixed screw 8 can ensure the fixing effect of the cathode tank block 1, the anode tank block 2 and the electrolytic assembly, and two of them can be selected as positive and negative electrodes. The fixed screw 8 uses the power line to connect the positive and negative poles of the power supply respectively. When in use, ensure that the anode electrode material is only in close contact with the anode screw and does not contact with the other screws.

Driven by the front and rear piston blocks 36, the pull plate 38 can drive the piston block 36 on the pull rod 40 to move in the same direction. In this way, under the movement of the middle piston block 36, the vacuum effect of the middle circular cavity 31 can be guaranteed, and then the middle circular cavity 31 will extract the liquid in the anode solution adding shell 14 through the suction port 35 and the suction cavity 32 and the anode solution input pipe 16. When the front and rear piston blocks 36 move to the pressure relief port 9 position, the gas will flow out. In this way, the front and rear two piston blocks 36 are The pressure in the circular cavity 31 will decrease, and under the elastic force of the spring 41, the front and rear piston blocks 36 are pushed to move in the opposite direction of the original moving direction, thereby ensuring that the middle piston block 36 pushes the liquid in the middle circular cavity 31 into the anode tank block 2 through the outlet pipe 33, thereby ensuring the replenishment of the substance in the anode tank block 2 and the concentration of the substance. The check valve 34 in the suction cavity 32 can ensure that the liquid flows into the circular cavity 31 through the anode solution input pipe 16, and will not allow the liquid in the circular cavity 31 to flow back to the anode solution input pipe 16, while the check valve 34 in the outlet pipe 33 can only ensure that the liquid in the circular cavity 31 flows into the anode tank block 2 and is blocked in the reverse direction. In this way, under the elastic force of the spring 41 and the gas delivery conditions of the anode gas output pipe 13, the left and right reciprocating motion of the central piston block 36 is guaranteed, which ensures the replenishment of the liquid in the anode tank block 2 and improves the reaction effect. The oxidation product output pipe 15 in the anode tank block 2 of the device is transported to the anode solution adding shell 14 under the transportation of the first power pump 17, so as to ensure the recycling effect of the solution in the anode solution adding shell 14. The liquid in the cathode tank block 1 is transported by the cathode liquid water pump 24 to the cathode solution adding shell 22. When the yin and yang tank block structure is used, the electric heating tube 27 can increase the internal temperature, thereby increasing the reaction rate of electrolysis and ensuring the full reaction. Each group of three settings of the starting switch 26, when one starting switch 26 is started, the two electric heating tubes 27 in the heating component will be started, and then another starting switch 26 will be started. When the start switch 26 is turned on, four electric heating tubes 27 in the heating component will be started. When three start switches 26 are turned on at the same time, the electric heating tubes 27 in each group of heating components will all be started. When one start switch 26 is started, the temperature in the special-shaped heating chamber 25 is 300-400 degrees Celsius. When two start switches 26 are started, the temperature in the special-shaped heating chamber 25 is 600-750 degrees Celsius. When all three start switches 26 are started, the temperature in the special-shaped heating chamber 25 is 800-1100 degrees Celsius. The device can set a temperature sensor on the surface of the yin and yang groove block structure, which can better ensure the use effect of the device.
