Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization wastewater electrolysis equipment, in particular to a tubular electrolytic cell and an electrolytic cell system for desulfurization wastewater. Background Art

[0002] With the rapid development of industry, environmental pollution is becoming increasingly serious. Treatment of desulfurization wastewater has become a key and challenging issue in the environmental protection field. Desulfurization wastewater primarily originates from the wet flue gas desulfurization process in thermal power plants, particularly in the limestone-gypsum wet desulfurization process. This process involves the reaction of limestone with sulfur dioxide in the flue gas to form gypsum. During this process, chlorides, fluorides, and other impurities in the flue gas dissolve in the wash water, forming desulfurization wastewater that requires treatment. Tubular electrolytic cells are used to electrolyze desulfurization wastewater generated by thermal power plants.

[0003] When the existing tubular electrolytic cell for desulfurization wastewater electrolyzes the desulfurization wastewater, the desulfurization wastewater is only allowed to enter the tubular electrolytic cell with electrode rods for electrolysis reaction. The contact time and contact area between the desulfurization wastewater and the electrode rods cannot be extended, thereby reducing the electrolysis reaction rate of the tubular electrolytic cell for the desulfurization wastewater. The electrolysis reaction products adsorbed on the surface of the electrode rods cannot be scraped off, which further affects the contact between the desulfurization wastewater and the electrode rods, thereby reducing the electrolysis reaction rate of the tubular electrolytic cell for the desulfurization wastewater.

[0004] In view of the above problems, it can be found that it is difficult to avoid the above problems at the same time when using the existing tubular electrolyzers for desulfurization wastewater on the market.

The stabilizing sleeve 2112 can be used to limit the extension and contraction direction of the first compression spring 2113, thereby improving the extension and contraction stability of the first compression spring 2113.

[0024] The specific implementation of this embodiment is as follows: when it is necessary to use the tubular electrolytic cell to perform electrolytic reaction treatment on desulfurized wastewater, the tubular electrolytic cell is first placed on the horizontal ground manually, and the lower base plate 11 can be stably installed to the required position by manually using fixing structures such as bolts, and the upper top plate 13 can be stably supported on the lower base plate 11 by using multiple support columns 12 fixed on the lower base plate 11, and the spiral electrolytic tube 2101 can be fixed under the upper top plate 13 and on the lower base plate 11 by connecting the rod 2102 and the lower mounting column 2103, so that the spiral electrolytic tube 2101 can be stably used to perform electrolytic reaction treatment on desulfurized wastewater, and then the wastewater inlet pipe 15 is manually connected to the outside to transport desulfurized wastewater. The water pipeline is connected, and the flow control valve 14 is manually controlled to control the flow rate of the desulfurized wastewater transported into the spiral electrolysis tube 2101. Since the spiral electrolysis tube 2101 is in a conical spiral shape, the desulfurized wastewater transported into the spiral electrolysis tube 2101 by the wastewater inlet pipe 15 can flow in sequence in the spiral electrolysis tube 2101. Since there are multiple electrolysis boxes 2104 connected to the outside of the spiral electrolysis tube 2101, the first electrolysis rod 2108 can be fixedly extended to the inside of the spiral electrolysis tube 2101 by using multiple extension rods 2105 and mounting blocks 2107. Since multiple first spiral chutes 2110 are provided outside the first electrolysis rod 2108, the first electrolysis rod 2108 can be increased in the spiral electrolysis tube 2101. The desulfurized wastewater is in contact with the first electrolysis rod 2108, and a rotating slip ring 2114 is provided on the outer surface of the first electrolysis rod 2108, and a plurality of water flow impact plates 2116 are fixed outside the rotating slip ring 2114. As the desulfurized wastewater flows in the spiral electrolysis tube 2101, the water flow impact plates 2116 are driven to rotate the rotating slip ring 2114, and the first ball 2115 rotating in the rotating slip ring 2114 slides along the first spiral groove 2110 opened outside the first electrolysis rod 2108, so that the rotating slip ring 2114 can slide upward and rotate with the water flow impact plates 2116, so that the rotating slip ring 2114 sliding along the outside of the first electrolysis rod 2108 can be used to scrape the reactants generated outside the first electrolysis rod 2108, thereby The high-concentration desulfurized wastewater is brought into contact with the first electrolysis rod 2108 for electrolysis reaction until the first compression spring 2113 can be twisted and compressed to the maximum, and the water flow impact plate 2116 is not in contact with the desulfurized wastewater. At this time, the flow rate of the desulfurized wastewater in the spiral electrolysis tube 2101 is the fastest, and the water pressure of the desulfurized wastewater is the lowest. The elastic force in the first compression spring 2113 is released, and under the action of the water flow impact plate 2116, the rotating slip ring 2114 rotates in the opposite direction and moves downward along the first electrolysis rod 2108 until the rotating slip ring 2114 can contact the baffle 2109 at the bottom end of the first electrolysis rod 2108. At this time, the flow rate of the desulfurized wastewater in the spiral electrolysis tube 2101 is the slowest, and the water pressure of the desulfurized wastewater is the highest.Repeating the above steps will cause the rotating slip ring 2114 to rotate and slide with the water flow impact plate 2116 outside the first electrolysis rod 2108, thereby increasing the contact time and contact area between the first electrolysis rod 2108 and the desulfurized wastewater, thereby increasing the electrolysis reaction rate of the desulfurized wastewater.

[0025] Example 2: Please refer to Figure 2 、 Figure 3 and Figures 8-10 The present invention provides a technical solution: a tubular electrolytic cell for desulfurization wastewater. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The flow electrolysis mechanism 2 also includes a blocking buffer electrolysis unit 22. The blocking buffer electrolysis unit 22 is arranged on the back of the spiral electrolysis unit 21. The spiral electrolysis unit 21 is used in conjunction with the blocking buffer electrolysis unit 22. The blocking buffer electrolysis unit 22 is used to block and buffer the desulfurization wastewater with a faster flow rate to increase the contact area of ​​the electrolysis reaction.

[0026] As a further limitation of the flow electrolysis mechanism 2 of the present invention, the blocking buffer electrolysis unit 22 includes an electrolysis buffer box 2201, the output end of the spiral electrolysis tube 2101 is fixedly connected to the left side of the electrolysis buffer box 2201, the bottom surface of the electrolysis buffer box 2201 is fixedly connected to the upper surface of the lower bottom plate 11, the right side of the electrolysis buffer box 2201 is fixedly connected to the wastewater discharge pipe 2202, an upper cover 2203 is provided above the electrolysis buffer box 2201, and the bottom surface of the upper cover 2203 is fixedly connected to the waste solid collection box 2206, and the waste solid collection box 2206 is snap-connected to the electrolysis buffer box 2201. Inside, the upper surface of the waste solid collection box 2206 is fixedly connected to an exhaust pipe 2204, the output end of the exhaust pipe 2204 passes through the upper cover 2203 and extends to the top of the upper cover 2203, the right side of the waste solid collection box 2206 is provided with filter holes 2205 arranged in a circumferential manner at equal distances, each filter hole 2205 is connected to the wastewater discharge pipe 2202, the inner wall of the waste solid collection box 2206 is fixedly connected to two limit boxes 2207, the interior of the waste solid collection box 2206 is slidably connected to two blocking buffer plates 2208, and the two blocking buffer plates 2208 are close to each other on one side. The left side of each blocking buffer plate 2208 is in contact with the inner wall of the electrolysis buffer box 2201. The right side of each blocking buffer plate 2208 is fixedly connected with a guide slide 2209. The two guide slides 2209 are respectively slidably connected to the inside of the two limit boxes 2207. The left side of each limit box 2207 is fixedly connected with two second compression springs 2210. The left ends of the two second compression springs 2210 are respectively fixedly connected to the right sides of the two blocking buffer plates 2208. The inner walls of the two second compression springs 2210 are respectively in contact with the outer surfaces of the two guide slides 2209. By setting up a blocking buffer electrolysis unit 22, the desulfurization wastewater transported by the spiral electrolysis tube 2101 can be utilized, and the flow rate of the desulfurization wastewater is sometimes large and sometimes small, which will impact the blocking buffer plate 2208 sliding in the waste solid collection box 2206. The second compression spring 2210 fixed between the blocking buffer plate 2208 and the limit box 2207 can be used to buffer the flowing desulfurization wastewater, so that the desulfurization wastewater can be further brought into contact with the electrolysis rod in the electrolysis buffer box 2201 to generate an electrolysis reaction, thereby further improving the electrolysis reaction rate of the tubular electrolytic cell for the desulfurization wastewater.

[0027] The specific implementation of this embodiment is as follows: after the multiple first electrolysis rods 2108 carry out electrolysis reaction with the desulfurized wastewater in the spiral electrolysis tube 2101, the desulfurized wastewater after the reaction will be transported to the electrolysis buffer box 2201, and by manually covering the upper cover 2203 on the electrolysis buffer box 2201, the waste solid collection box 2206 fixed on the bottom surface of the upper cover 2203 can be stuck into the interior of the electrolysis buffer box 2201, and since the output end of the spiral electrolysis tube 2101 is connected to the waste solid collection box 2206, and the filter hole 2205 opened on one side of the waste solid collection box 2206 can be used to filter the desulfurized wastewater in the waste solid collection box 2206. Water is filtered, and the filtered desulfurized wastewater is transported outward through the wastewater discharge pipe 2202, and the solid matter generated by the electrolysis reaction filtered out of the desulfurized wastewater is filtered into the waste solid collection box 2206 for collection. Then, due to the arrangement of multiple rotating slip rings 2114 in the spiral electrolysis tube 2101, the water flow impact plate 2116 rotates and moves along the first electrolysis rod 2108, which can cause the desulfurized wastewater in the spiral electrolysis tube 2101 to form a situation where the water pressure is large and the water pressure is small. By fixing two limit boxes 2207 in the waste solid collection box 2206, two slidable blocking buffer plates 2208 can be arranged in the waste solid collection box 2206, and the use of The blocking buffer plate 2208 is used to block the connection between the spiral electrolysis tube 2101 and the electrolysis buffer box 2201. Since the desulfurization wastewater transported into the electrolysis buffer box 2201 will push the two blocking buffer plates 2208, a second compression spring 2210 is fixed between the blocking buffer plate 2208 and the limit box 2207, which can make the guide slide 2209 fixed on one side of the blocking buffer plate 2208 slide along the limit box 2207 to compress the second compression spring 2210, so that the blocking buffer plate 2208 can be kept away from the connection between the spiral electrolysis tube 2101 and the electrolysis buffer box 2201, and the transported desulfurization wastewater can be pushed. The buffer is transported into the waste solid collection box 2206 through the gap between the blocking buffer plate 2208 and the waste solid collection box 2206, which can reduce the flow rate of the desulfurization wastewater, thereby increasing the flow time of the desulfurization wastewater in the electrolysis buffer box 2201, increasing the contact time between the desulfurization wastewater and the electrolysis rod, and improving the electrolysis reaction rate of the desulfurization wastewater.
