Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a device for treating high-chlorine wastewater from non-ferrous metal smelting. Background Art

[0002] In the process of metal smelting, a large amount of water is needed for cooling or participating in other metal smelting links. After participating in metal smelting, these waters will become sewage containing a large amount of harmful substances. The wastewater from non-ferrous metal smelting contains a large amount of chlorine. If these wastewaters are directly discharged, it will cause great pollution to the environment. Therefore, the treatment of high-chlorine wastewater from non-ferrous metal smelting is very important for our industry and ecological environment. At present, there are many ways to treat high-chlorine wastewater on the market, and some treatment methods are relatively simple, which will lead to the treatment effect not reaching the ideal state.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN220149303U, patent name: a mechanism for dechlorinating industrial water) is: it includes a water inlet pipe, a power unit, a filter unit and a water outlet pipe, the power unit includes a pump and a connecting pipe, the water inlet end of the pump is connected to the water inlet pipe, and the water outlet end of the pump is connected to one end of the connecting pipe; the other end of the connecting pipe is connected to the filter unit; the filter unit includes a filter tank, a partition, a baffle and filter material, the filter tank is a capsule-type hollow tank, there are two partitions, both of which are provided with a plurality of fixing holes, the two partitions are arranged in parallel in the filter tank, and the filter tank is divided into three cavities, the three cavities are the first cavity, the second cavity and the third cavity from top to bottom; the side of the third cavity is connected to the other end of the connecting pipe; the side of the first cavity is connected to the water outlet pipe; there are two baffles, the baffles are fixedly connected to the side wall of the second cavity, and there is a continuously curved baffle channel between the baffle and the side wall of the second cavity; the filter material is located in the baffle channel, so that the mechanism is suitable for dechlorinating industrial water.

[0004] It can be seen from the above implementation scheme that the dechlorination mechanism only uses filtering to remove chlorine. After a period of filtration, the adsorption capacity of the chlorine material decreases, which will affect the filtration effect and make the treated wastewater substandard. Summary of the invention

[0005] The present invention overcomes the shortcomings of the prior art and is provided with an electrolysis component and a flocculation reaction tank.

DETAILED DESCRIPTION

[0051] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] like Figures 1 to 16As shown, a non-ferrous metal smelting high-chlorine wastewater treatment device is used for electrolyzing non-ferrous metal smelting high-chlorine wastewater, and then performing a flocculation reaction, and then dialysis purifying water through a high-strength membrane tube 8, including an electrolysis component 1, and the electrolysis component 1 includes an electrolytic cell 101. One end of the bottom of the electrolytic cell 101 is higher than the other end, so that the solids precipitated in the wastewater after electrolysis will flow from the high end to the low end along the inclined surface of the bottom of the electrolytic cell 101, and finally be sucked away at the bottom of the electrolytic cell 101. A positive electrode electrolysis rod 106 and a negative electrode electrolysis rod 107 are provided in the electrolytic cell 101. An electrolysis circulation component 105 is also provided in the electrolytic cell 101. The electrolysis circulation motor 1051 is connected to a spiral agitator 1052, and the spiral agitator 1052 rotates to drive the wastewater in the electrolytic cell 101 to flow, so that the wastewater in the electrolytic cell 101 can be fully electrolyzed.

[0053] A circulating heating component 102 is arranged on the side of the electrolytic cell 101, and the circulating heating component 102 is connected to a pumping pipe 103 and a return pipe 104. The other end of the pumping pipe 103 is connected to the higher end of the bottom of the electrolytic cell 101, and one end of the return pipe 104 is connected to the top of the electrolytic cell 101. A heating mechanism and a pumping pump are arranged inside the circulating heating component 102. The pumping pump draws wastewater from the higher end of the bottom of the electrolytic cell 101 to avoid drawing waste residue from the electrolysis. The wastewater is heated by the circulating heating component 102 and finally returned to the electrolytic cell 101 through the return pipe 104. The circulating heating component 102 allows the water in the electrolytic cell 101 to flow, and can also heat the wastewater according to the temperature requirements during electrolysis, so that the wastewater is electrolyzed at the most suitable temperature, thereby accelerating the speed of wastewater electrolysis.

[0054] The electrolytic component 1 is connected to the flocculation reaction tank 2, which includes a dosing tank 201, a stirring reaction tank 203, a large-particle reactant forming tank 204 and a waste sedimentation tank 207; the large-particle reactant forming tank 204 is provided with an overflow plate 6 at the top and a water raising component 7 at the bottom; a plurality of high-strength membrane tubes 8 are provided above the waste sedimentation tank 207, and a flushing water pipe 9 is interspersed between every two high-strength membrane tubes 8; the high-chlorine wastewater is first electrolyzed in the electrolytic component 1, and then transported to the flocculation reaction tank 2, the wastewater first passes through the dosing tank 201, at which time flocculants are added to the wastewater, and then transported to the stirring reaction tank 203, so that the wastewater and the flocculants react fully, and then are transported to the large-particle reactant forming tank 204, The water raising component 7 causes the wastewater to form a vortex that rotates upward on the periphery and sinks in the center. Large particles of solids are formed in the reacted wastewater, which overflows through the overflow plate 6, and the large particles of solids therein are precipitated downward from the central vortex; the wastewater then comes to the top of the waste sedimentation tank 207, where water molecules penetrate into the inside of the high-strength membrane tube 8 through the outside of the high-strength membrane tube 8 and are output to the next process, while other crystals, microorganisms, and suspended matter are blocked on the outside of the high-strength membrane tube 8. The outside of the high-strength membrane tube 8 is flushed by the water flushed out by the flushing water pipe 9, and the crystals, microorganisms, and suspended matter attached to the outside thereof are washed off and fall into the waste sedimentation tank 207. Therefore, the wastewater is gradually degraded to finally obtain fully purified water.

[0055] A reactant input component 3 is arranged above the dosing tank 201, and the reactant input component 3 includes a sewage inlet 301 and a flocculant inlet 302; sewage enters from the sewage inlet 301, and flocculant enters from the flocculant inlet 302, and the two are preliminarily mixed inside the dosing tank 201. A mixing component 4 is arranged inside the dosing tank 201, and the mixing component 4 includes a mixing motor 401, and the mixing motor 401 is connected to a mixing roller 402. A plurality of arc-shaped blades 4021 are arranged in a ring around the mixing roller 402. The mixing roller 402 rotates, driving the sewage and the flocculant to flow from the upper inlet to the lower outlet of the dosing tank 201, and at the same time, the sewage and the flocculant are mixed.

[0056] A first circulation waterway 202 is arranged between the dosing tank 201 and the stirring reaction tank 203, and the first circulation waterway 202 includes a first bottom water inlet channel 2021 and a first top water inlet channel 2022. Wastewater flows from the bottom of the dosing tank 201 to the first bottom water inlet channel 2021, then flows from the top of the first bottom water inlet channel 2021 to the first top water inlet channel 2022, and then flows from the bottom of the first top water inlet channel 2022 to the stirring reaction tank 203; the sewage is transported from the dosing tank 201 to the stirring reaction tank 203 through the first circulation waterway 202, so that the sewage can flow at a certain flow rate, so that the sewage must be stirred by the mixing component 4 before it can be transported to the stirring reaction tank 203, and the transportation distance also reserves a certain reaction time for the sewage and the flocculant.

[0057] The stirring reaction tank 203 is provided with a circulating stirring power component 5, which includes a stirring motor 501, which is connected to a stirring roller body 502, and the stirring roller body 502 includes a hollow circulating flow tube 5021, and the hollow circulating flow tube 5021 is provided with an inner spiral blade 5022 inside and an outer spiral blade 5023 outside. The inner spiral blade 5022 rotates in the opposite direction to the outer spiral blade 5023, as shown in FIG. Fig.10 As shown, when the inner spiral blade 5022 and the outer spiral blade 5023 rotate, the sewage is driven to flow from the inside of the hollow circulation pipe 5021 to the outside thereof, and the sewage is brought from the outside of the hollow circulation pipe 5021 to the inside thereof, so that the sewage forms a certain circulation loop in the stirring reaction tank 203, and the sewage input from the dosing tank 201 participates in the flow of the circulation loop. A second circulation waterway 2031 is provided between the stirring reaction tank 203 and the large particle reactant forming tank 204; and as the sewage increases, the sewage on the side away from the dosing tank 201 flows from the second circulation waterway 2031 to the large particle reactant forming tank 204, thereby ensuring a sufficient mixing reaction of the sewage and the flocculant, so that the sludge in the sewage is aggregated into sludge masses under the action of the flocculant, which facilitates the large particle reactant forming tank 204 to precipitate the sludge masses in the sewage. At this time, the color of the sewage becomes lighter, and large pieces of sludge masses float in the sewage.

[0058] A large particle reactant sedimentation tank 2041 is provided at the lower end of the large particle reactant forming tank 204. The large particle reactant sedimentation tank 2041 is in the shape of an inverted truncated cone, and the bottom of the large particle reactant sedimentation tank 2041 leads to a sludge collection tank. A water raising component 7 is arranged inside the large particle reactant sedimentation tank 2041, and the water raising component 7 includes a water raising rotor 701. The water raising rotor 701 is in the shape of an inverted frustum. The shape of the water raising rotor 701 matches the large particle reactant sedimentation tank 2041. A sludge return hole 7011 is arranged in the middle of the water raising rotor 701, and the water raising rotor 701 is provided with a water raising rotating blade 7012 in a ring shape in the circumferential direction; the inverted frustum structure of the water raising rotor 701 makes the upper end of the water raising rotor 701 stir the water body with great force, which is conducive to the rising of the water body, while its lower end is narrowed to reduce the stirring of the water body, which will not affect the sedimentation of sludge in the sludge collection tank at the lower end; the water raising rotor 701 is connected to the self-rotating gear 702 at the bottom, and the self-rotating gear 702 is meshed and connected with the transmission gear 703, and the transmission gear 703 is externally connected to a driving motor. The water lifting rotor 701 rotates, and the water lifting rotating blades 7012 drive the water around the sludge return hole 7011 to rotate. The water rotates to form a rotating upward water flow, and the water flow is mixed with clumps of sludge. A guide bend pipe is arranged inside the overflow plate 6. The guide bend pipe is composed of a first inner inclined tube 601 and a second inner inclined tube 602 that are connected. The angle between the first inner inclined tube 601 and the second inner inclined tube 602 is less than ninety degrees, so that the water flow can smoothly pass through the first inner inclined tube 601 and the second inner inclined tube 602. After the sludge mass passes through the second inner inclined tube 602, it will be blocked by the inside of the first inner inclined tube 601 because it goes upward, and there is a water flow formed by the water lifting rotor 701 below that flows to the sludge return hole 7011 in the middle of the water lifting rotor 701. In addition, the weight of the sludge itself is greater than the weight of water molecules, so the sludge will fall. The first inner inclined tube 601 leads to the upper surface of the overflow plate 6, and the second inner inclined tube 602 leads to the lower surface of the overflow plate 6. Water and sludge enter from the bottom of the second inner inclined tube 602. When the sludge flows to the junction of the first inner inclined tube 601 and the second inner inclined tube 602, the top of the sludge hits the inside of the first inner inclined tube 601 and cannot rise. The fallen sludge flows to the sludge collection tank through the sludge return hole 7011 along with the water flow stirred by the water lifting rotor 701, thereby separating the sludge and water precipitated from the sewage. The water overflows from the top of the overflow plate 6 through the guide bend pipe. At this time, the water visible to the naked eye has become clear, but the water still contains many small particles of crystals, microorganisms, and suspended matter.

[0059] A third circulation waterway 205 is provided between the large particle reactant forming pool 204 and the high-strength membrane tube 8. The third circulation waterway 205 includes a second top water inlet channel 2051, a second bottom water inlet channel 2052 and a third top water inlet channel 2053. After the wastewater overflows from the overflow plate 6, it flows in from the top of the second top water inlet channel 2051, then flows from the bottom of the second top water inlet channel 2051 to the second bottom water inlet channel 2052, then flows from the top of the second bottom water inlet channel 2052 to the third top water inlet channel 2053, and finally flows from the bottom of the third top water inlet channel 2053 to the transverse waterway 206. The water flows in an overflow manner, so that a small part of the agglomerated sludge brought out when passing through the overflow plate 6 will settle down in the slow flow of the water body, making the water flowing to the next link cleaner.

[0060] A bottom infiltration mechanism 208 is arranged above the transverse waterway 206. The bottom infiltration mechanism 208 comprises two symmetrical collecting inclined plates 2083. Infiltration channels 2082 are arranged on both sides of the collecting inclined plates 2083. A waste sedimentation tank 2081 is arranged between the two collecting inclined plates 2083. Figure 8 and Fig. 9 It can be seen that the waste sedimentation tank 2081 has only one end in the middle and does not extend to both sides. Therefore, the transverse waterways 206 on both sides of the waste sedimentation tank 2081 are connected to the infiltration channel 2082, and the water flows from the transverse waterway 206 through the infiltration channel 2082 to the top of the bottom infiltration mechanism 208; as the water body increases, the water body spreads to the periphery of the high-strength membrane tube 8 until the bottom of the high-strength membrane tube 8 is immersed in the water body. As the water body is still increasing, the pressure generated by the water body causes the water molecules to penetrate through the side wall of the high-strength membrane tube 8 and penetrate into the middle of the high-strength membrane tube 8, and finally output from the upper end of the high-strength membrane tube 8, while the crystals and micro-particles in the water body are Organisms and suspended matter are isolated to the outside of the high-strength membrane tube 8. When a part of the water body has passed through and the water purification stops, the flushing water pipe 9 will be opened. A number of high-pressure flushing nozzles are arranged on the flushing water pipe 9. The flushing water pipe 9 is staggered with the high-strength membrane tube 8 on the cross section perpendicular to the high-strength membrane tube 8. In this embodiment, there are two groups of flushing water pipes 9, and the two groups of flushing water pipes 9 are perpendicular to each other, so that the outer periphery of the high-strength membrane tube 8 can be flushed clean. The waste sedimentation tank 2081 in the middle is connected to the waste sedimentation tank 207; the waste flushed from the outside of the high-strength membrane tube 8 flows into the waste sedimentation tank 207 through the waste sedimentation tank 2081.

[0061] When purifying the water body, the sewage outlet of the waste sedimentation tank 207 is closed, so that the water can overflow the tank, so that the water can only precipitate through the high-strength membrane tube 8. When the outside of the high-strength membrane tube 8 is flushed, the sewage outlet of the waste sedimentation tank 207 is opened, and the sewage flushed from the outside of the high-strength membrane tube 8 is discharged from the sewage outlet of the waste sedimentation tank 207.

[0062] The flushing water pipe 9 prevents the high-strength membrane tube 8 from being blocked, so that the high-strength membrane tube can maintain a good water purification effect.

[0063] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
