Description

Technical Field

[0001] The utility model relates to the technical field of micro-electrolysis equipment, in particular to an iron-carbon micro-electrolysis device for epoxidation reaction wastewater. Background Art

[0002] Since epoxide generates epoxy homopolymer and copolymer under the catalysis of high temperature, strong ions or free radicals, it is an important industrial raw material. Wastewater will be generated during the epoxidation reaction, and the wastewater often contains high iron and carbon elements, so it is necessary to use electrolytic equipment to treat the wastewater. Micro-electrolysis technology is an ideal process for treating high-concentration organic wastewater. It can use micro-electrolysis materials filled in wastewater to electrolyze wastewater without electricity to achieve the purpose of degrading organic pollutants. When the micro-electrolysis device is electrolyzed, micro-electrolysis materials are filled in the electrolytic cell or electrolytic cylinder, and electrolysis is carried out by the electricity generated by the micro-electrolysis materials. The micro-electrolysis materials are directly filled and set, and the water flow cannot be fully and repeatedly released from the micro-electrolysis materials, which makes this method more wasteful of materials, cannot be fully utilized, causes waste, and the electrolysis effect is not good enough. Secondly, when the sewage enters the electrolytic cylinder, it cannot spread evenly and automatically, and the water distribution is not uniform, which in turn affects the sewage treatment effect, so it needs to be improved.

The utility model connects a circular water divider by rotating at the center of a water distribution plate, and connects a plurality of arc-shaped drain pipes on the side wall of the circular water divider. When water enters, wastewater enters the arc-shaped drain pipe through a water inlet hose, a connecting pipe, and a circular water divider in sequence, and the wastewater is sprayed out through a nozzle on one side of the arc-shaped drain pipe.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1 and Figure 2 As shown, an iron-carbon micro-electrolysis device for epoxidation wastewater proposed in one embodiment of the utility model comprises an electrolytic cylinder 1, and a cylinder cover 5 fixedly connected to the top of the electrolytic cylinder 1, a connecting pipe 10 is axially fixed at the center of the cylinder cover 5, and a water distribution plate 3 is fixed to the inner upper part of the electrolytic cylinder 1, a circular water divider 11 is rotatably connected to a rotating seat 13 arranged at the center of the water distribution plate 3, the connecting pipe 10 extends to the inner side of the circular water divider 11, and the side wall of the circular water divider 11 is axially fixed to the inner upper part of the electrolytic cylinder 1. A plurality of arc-shaped drainage pipes 12 distributed in an array are connected to the circular water divider 11. A rotating rod 9 is axially fixed at the center of the lower surface of the circular water divider 11. The lower end of the rotating rod 9 is rotatably connected to the inner bottom of the electrolysis cylinder 1, and a spiral orifice plate 2 is fixed on the rotating rod 9. Micro-electrolysis materials are fixed on the spiral orifice plate 2. When water passes through the circular water divider 11, the reverse driving force of the water in the arc-shaped drainage pipe 12 can be used to drive itself, the circular water divider 11 and the rotating rod 9 to rotate, and the sewage is continuously electrolyzed by the high-speed rotating spiral orifice plate 2.

[0022] It should be noted that by fixing the connecting pipe 10 at the center of the cylinder cover 5, the connecting pipe 10 can guide the wastewater into the inner side of the electrolytic cylinder 1, and by fixing the water distribution plate 3 on the inner upper part of the electrolytic cylinder 1, the water distribution plate 3 is used for uniform water distribution of the wastewater, and the installation of the circular water divider 11 and other components is realized. The circular water divider 11 is rotatably connected to the rotating seat 13 of the water distribution plate 3, so that the circular water divider 11 can rotate, and by connecting a plurality of arc-shaped drainage pipes 12 on the side wall of the circular water divider 11, the wastewater enters the arc-shaped drainage pipe 12 in turn through the connecting pipe 10 and the circular water divider 11, and the wastewater is discharged. Uniform discharge. The discharge process can generate a reverse thrust, so that the circular water divider 11 rotates rapidly on the rotating seat 13. A rotating rod 9 is set between the lower surface of the circular water divider 11 and the inner bottom of the electrolysis cylinder 1, and a spiral orifice plate 2 is fixed on the outer wall of the rotating rod 9. When the circular water divider 11 rotates, the rotating rod 9 rotates accordingly, thereby causing the spiral orifice plate 2 to rotate rapidly. Micro-electrolysis materials are fixed on the spiral orifice plate 2. When the spiral orifice plate 2 rotates rapidly, it can frequently and quickly contact with the wastewater, thereby increasing the contact frequency between the wastewater and the micro-electrolysis materials, and thereby increasing the wastewater treatment effect.

[0024] It should be noted that by connecting multiple equally distributed nozzles 14 on one side of the arc-shaped drain pipe 12, when water is passed, the wastewater is discharged evenly through the nozzles 14. This method is conducive to the uniform discharge of wastewater on the one hand. Secondly, the water flow pushes the arc-shaped drain pipe 12 positively, which is conducive to the arc-shaped drain pipe 12 to generate a reverse thrust, so that the arc-shaped drain pipe 12, the circular water divider 11, and the rotating rod 9 rotate quickly, increasing the rotation speed of the spiral orifice plate 2, and then increasing the wastewater treatment effect. By tilting the nozzle 14 downward, the water flow is prevented from being sprayed directly onto the inner wall of the electrolytic cylinder 1, which is conducive to the uniform discharge of wastewater.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments, the rotating rod 9 is rotatably connected to the water distribution plate 3 and the rotating seat 13 , and the upper end of the rotating rod 9 is connected to the circular water distributor 11 through a hole opened in the rotating seat 13 .

[0026] It should be noted that the rotating rod 9 rotates on the water distribution plate 3 and the rotating seat 13. When the circular water divider 11 rotates, the rotating rod 9 can be driven to rotate.

[0027] like Figure 1 As shown, in some embodiments, the water distribution plate 3 is provided with drainage holes 4 distributed in an array, so that the wastewater is evenly discharged into the lower inner side of the electrolytic tube 1, and contacts the micro-electrolysis material on the spiral hole plate 2 for electrolytic treatment.

[0028] like Figure 1 As shown, in some embodiments, a water pump 7 is installed on the cylinder cover 5, and a water inlet hose 6 is connected between the water outlet of the water pump 7 and the top of the connecting pipe 10, and a water outlet pipe 8 is connected to the bottom of the electrolytic cylinder 1.

[0029] It should be noted that, by installing a water pump 7 on the cylinder cover 5 , the water pump 7 can discharge waste water into the water inlet hose 6 , and then enter the connecting pipe 10 , the circular water distributor 11 , the arc-shaped drain pipe 12 in sequence, and then be uniformly ejected through the nozzle 14 .

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
