Technical Field

[0001] The invention relates to the field of sewage treatment equipment, and in particular to a high-efficiency treatment device for waste acid sewage in a copper smelting project. Background Art

[0002] The waste acid stock solution in the copper smelting project is mainly produced in the sulfuric acid fume purification section. It has high acidity and high content of harmful substances such as heavy metals. It has the characteristics of strong corrosiveness and complex water quality. The traditional treatment method not only has high operating costs and low comprehensive recovery rate, but also has unsatisfactory treatment effect. The existing waste acid sewage treatment system adopts sulfide arsenic precipitation process, which can precipitate arsenic in the waste acid solution and remove a large amount of arsenic pollution, but the removal effect of other heavy metal elements is poor, and the treatment efficiency of the waste acid sewage treatment device in the prior art is low, resulting in a small treatment volume per unit time, which cannot meet production needs. At the same time, the waste acid sewage treatment system in the prior art cannot perform deep treatment on the waste acid solution, resulting in poor treatment quality of the waste acid solution.

In the process of heating and disinfection, some harmful gases will be released by the heated water.

[0018] The heated and disinfected water is discharged through the drain outlet. The drain outlet, the valve body inside the partition plate and the heating rack are all opened at intervals to achieve segmented operation, which is beneficial to practical use.

[0030] like Figure 1-Figure 9The waste acid sewage high-efficiency treatment device in a copper smelting project shown in the figure comprises a sewage treatment barrel 1, the sewage treatment barrel 1 comprises a barrel body 101, the barrel body 101 is rotatably connected to an inner cylinder 123 in the middle and upper part, the inner cylinder 123 is provided with uniformly distributed through holes 131 in the middle and upper part of the outer periphery, the through holes 131 are fixedly connected to a limiting ring 124 at the upper part of the outer periphery, the limiting ring 2 133 is fixedly connected to the lower part of the outer periphery of the through holes 131, the limiting ring 124 and the limiting ring 2 133 are both provided with limiting openings on one side, and the inner cylinder 123 is rotatably connected to the middle and lower part of the outer periphery. An outer cylinder 128 is provided, and a limiting block 129 is fixedly connected to the upper part of one side of the outer circumference of the outer cylinder 128, and a limiting block 132 is fixedly connected to the lower part of one side of the outer circumference of the outer cylinder 128. The limiting block 129 and the limiting block 132 are both arranged on the inner side of the limiting opening. A through hole 127 is evenly distributed on the upper part of the outer circumference of the outer cylinder 128. A sewage pipe 112 is fixedly connected to the middle part of the bottom end of the inner cylinder 123. A downflow port 134 is installed in the upper part of the sewage pipe 112. A valve body is arranged inside the downflow port 134. The bottom of the sewage pipe 112 passes through the middle part of the bottom end of the barrel body 101.

[0031] Furthermore, in the specific implementation, during the treatment of the waste acid sewage, people can start the servo motor 103, and the servo motor 103 can drive the rotating shaft 125 to rotate clockwise. When the rotating shaft 125 rotates, it will drive the inner cylinder 123 to rotate synchronously through the connecting frame 126. The inner edge of the limiting opening can be used to resist the limiting block 129 and the limiting block 2 132 through the limiting ring 124 and the limiting ring 2 133, so that the inner cylinder 123 can drive the outer cylinder 128 to rotate synchronously. At this time, the outer cylinder The through hole 127 on 128 and the through hole 2 131 on the inner cylinder 123 are in a misaligned state, so that the inner cylinder 123 is in a closed state at this time. During this process, the guide plate 130 and the top ring 135 on the inner side of the inner cylinder 123 will rotate synchronously with the inner cylinder 123 driven by the friction force of the annular groove 136 and the guide ring 137. The sewage and the reagent inside the inner cylinder 123 can be fully stirred through the guide plate 130, so that the waste acid sewage can fully react with the treatment reagent under high-speed rotation, thereby accelerating the reaction and precipitation rate.

[0032] Among them, an end cover 102 is installed on the top of the barrel body 101, a servo motor 103 is installed in the middle of the top of the end cover 102, a rotating shaft 125 is fixedly connected to the bottom driving end of the servo motor 103, the rotating shaft 125 passes through the middle of the end cover 102 and is rotatably connected to the end cover 102, the upper and lower parts of the outer circumference of the rotating shaft 125 are fixedly connected to connecting frames 126, the connecting frames 126 are respectively installed in the upper and lower parts of the inner tube 123, and a plurality of top columns 139 are fixedly connected to the top of the lower connecting frame 126, a water inlet pipe 104 is installed on one side of the top of the end cover 102, and a medicine inlet pipe 105 is installed on the other side of the top of the end cover 102, and a plurality of inspection ports 108 are opened in the middle of the outer circumference of the barrel body 101, and sealing doors 110 are installed at the ends of the inspection ports 108;

[0033] Furthermore, in a specific implementation, people can introduce waste acid sewage from the copper smelting project into the inner cylinder 123 in the barrel body 101 through the water inlet pipe 104, and can introduce the reagents required for treatment into the inner cylinder 123 through the drug inlet pipe 105, such as alkaline solution, sulfide solution, calcium salt solution, etc. The waste acid sewage is neutralized by the alkaline solution {such as lime milk}, so that most of the copper metal ions in the sewage will form precipitation, and the sulfide solution {such as sodium sulfide solution} can react with arsenic compounds in the sewage to produce arsenic sulfide, and the calcium salt solution {such as calcium chloride solution, calcium hydroxide solution, etc.} can react with fluoride in the sewage to produce calcium fluoride precipitation.

[0034] Among them, reciprocating thread segments 143 are provided on the upper and lower sides of the middle of the outer circumference of the rotating shaft 125, and the outer circumference of the rotating shaft 125 is threadedly connected to the fixing sleeve 122 through the reciprocating thread segment 143, and the outer circumference of the fixing sleeve 122 is fixedly connected to the soft rubber disc 142, and the middle of the side close to the soft rubber disc 142 is fixedly connected to the soft cavity 144, and the outer side of the middle of the soft rubber disc 142 is provided with evenly distributed perforations 141, and the middle of the soft rubber disc 142 and the soft cavity 144 are provided with evenly distributed empty holes 145, and the soft rubber disc 142 is symmetrically arranged, and the outer circumference of the end away from the soft rubber disc 142 is fixedly connected to a plurality of stirring rods 146;

[0035] Furthermore, in a specific implementation, during the reaction process, when the rotating shaft 125 rotates, the soft rubber disc 142 and the fixed sleeve 122 will be driven by the rotating shaft 125 to rotate, but under the action of gravity and sewage resistance, the soft rubber disc 142 and the fixed sleeve 122 will form a speed difference with the rotating shaft 125, so that the fixed sleeve 122 will form a relative motion with the rotating shaft 125. The reciprocating threaded section 143 on the rotating shaft 125 will guide the fixed sleeve 122 when the fixed sleeve 122 rotates relatively around the outer periphery of the rotating shaft 125, so that the fixed sleeve 122 can drive the soft rubber disc 142 to move up and down around the outer periphery of the rotating shaft 125, thereby realizing the separation of sewage and medicine inside the inner cylinder 123. To fully spread the water, the upper and lower soft rubber discs 142 will continuously perform an "opening and closing" movement. When the soft rubber discs 142 are "closed", the sewage between the soft rubber discs 142 will be discharged through the perforations 141 and the empty holes 145 respectively under the pressure of the soft rubber discs 142 to form a "jet". The "jet" can impact the inner wall of the inner tube 123 to prevent the compounds and precipitates at the reaction site from adhering to the inner wall of the inner tube 123 for a long time to form solid scale. When the soft rubber discs 142 are "separated", part of the sewage will pass through the perforations 141 and the empty holes 145 to form a "turbation". The "turbation" can further stir and disperse the sewage and the treatment agent to accelerate the reaction process, which is beneficial to actual use.

[0036] Among them, a top ring 135 is arranged at the upper inner part of the inner cylinder 123, a guide ring 137 is fixedly connected to the upper inner part of the inner cylinder 123, the guide ring 137 is rotatably connected to the inner side of the annular groove 136, the annular groove 136 is arranged at the middle part of the outer circumference of the top ring 135, the bottom of the top ring 135 is fixedly connected to the evenly distributed guide plates 130, the bottom ends of the guide plates 130 are fixedly connected to the contact pieces 140, the guide plates 130 and the contact pieces 140 are both inclinedly arranged, an anti-reverse cone 138 is installed at the middle and lower part of the inner cylinder 123, and the bottom of the contact pieces 140 is in contact with the top of the anti-reverse cone 138;

[0037] Furthermore, in a specific implementation, when the preset reaction time is reached, the servo motor 103 stops rotating, and when the inner cylinder 123 and the rotating shaft 125 stop rotating synchronously, the top ring 135 and the guide plate 130 rotate relative to the guide ring 137 under the action of inertia, and when the top ring 135 and the guide plate 130 continue to rotate, the guide plate 130 cleans the inner wall of the inner cylinder 123 when rotating, and scrapes off the reacted sediment attached to the inner wall of the inner cylinder 123, so that the sediment is The contact piece 140 at the bottom of the guide plate 130 can fall to the bottom of the inner cylinder 123, and the contact piece 140 at the bottom of the guide plate 130 will continuously contact the top column 139 on the bottom connecting frame 126. The contact piece 140 will be moved through the collision contact between the top column 139 and the contact piece 140. The vibration generated when the contact piece 140 is moved will be transmitted to the guide plate 130. Through the continuous vibration of the guide plate 130, the sediment attached to the guide plate 130 can be shaken off as much as possible to reduce the residue, which is beneficial to the discharge of sediment and impurities.

[0038] Among them, a rotating frame 117 is rotatably connected to the middle and lower part of the barrel body 101, and the rotating frame 117 is driven to rotate by a stepper motor. The stepper motor is installed on one side of the sewage treatment barrel 1, and a partition frame 118 is installed on the top of the rotating frame 117. The partition frame 118 is rotatably connected to the upper part of the barrel body 101. The outer periphery of the partition frame 118 is separated by a partition with a plurality of permeation chambers 120. The bottom of the permeation chamber 120 is provided with a plurality of connecting holes 115, and the connecting holes 115 are provided with valve bodies. The bottom of the permeation chamber 120 is provided with a reverse osmosis membrane 116, and the reverse osmosis membrane 116 is installed on the outer side of the middle part of the rotating frame 117. The rotating frame 117 is rotatably connected to the lower part of the outer periphery of the inner cylinder 123, and a central cavity is formed between the partition frame 118 and the outer cylinder 128.

[0039] Furthermore, in a specific implementation, after the servo motor 103 stops rotating, it is left to stand for a period of time to facilitate the sediment to sink to the bottom of the inner cylinder 123. Then the servo motor 103 works again and reverses. At this time, under the action of gravity and inertia, the outer cylinder 128 will be misaligned with the inner cylinder 123, and the limiting openings of the limiting ring 124 and the limiting ring 2 133 can limit the limiting blocks 129 and 132, so that the limiting blocks 129 and 132 are against the inner edge of the other side of the limiting openings. At this time, the outer cylinder 128 on the outer cylinder 128 and the through hole 2 131 on the inner cylinder 123 are in an overlapping state. At this time, the treated sewage inside the inner cylinder 123 will be discharged through the through hole 2 131 and the through hole 1 127, and enter the middle cavity between the outer side of the outer cylinder 128 and the partition frame 118, and the servo motor 103 The reversal drives the inner cylinder 123 and the outer cylinder 128 to rotate rapidly counterclockwise, so that the internal sewage can be quickly centrifuged and thrown out. Then the servo motor 103 rotates clockwise again, and the outer cylinder 128 is driven to deflect by gravity and inertia, so that the inner cylinder 123 and the outer cylinder 128 are closed again, which is convenient for the next sewage treatment. When the sewage is introduced into the middle cavity, the valve body inside the downflow port 134 is opened, and the compounds and sediments at the reaction site are discharged from the sewage treatment barrel 1 through the sewage pipe 112 for subsequent treatment. In the process of leading out of the inner cylinder 123, the sewage will enter the osmosis chamber 120 through the connecting hole 115 at the lower part of the middle cavity. The reverse osmosis membrane 116 at the bottom of the osmosis chamber 120 can realize the osmosis filtration of the sewage, intercept the remaining fine impurities in the sewage, and introduce the water into the upper part of the partition plate 114.

A ring warehouse 107 is arranged on the upper part of the outer periphery of the barrel body 101, and a ring pipe 113 is arranged inside the ring warehouse 107. A uniformly distributed air inlet pipe 106 is arranged on the top of the ring pipe 113, and the end of the air inlet pipe 106 away from the ring pipe 113 penetrates the side wall of the barrel body 101. The air inlet pipe 106 The ends away from the annular tube 113 are connected to the inside of the permeation chamber 120, a heating rack 119 is installed at the bottom of the barrel body 101, a heating chamber is formed between the heating rack 119 and the partition plate 114, exhaust pipes 109 are arranged on both sides of the upper part of the heating chamber, the ends of the exhaust pipes 109 away from the heating chamber are fixedly connected to the bottom of the annular tube 113, a one-way valve is arranged inside the air inlet pipe 106 and the exhaust pipe 109, a plurality of drain ports 111 are opened at the bottom of the barrel body 101, and valve bodies are arranged inside the drain ports 111;

[0041] Furthermore, in a specific implementation, water can be introduced into the bottom of the sewage treatment barrel 1 through the discharge port 121 on the partition plate 114, and the treated water can be heated and disinfected through the operation of the heating rack 119 to achieve sufficient treatment of the water. In the process of heating and disinfection, some harmful gases will be released by the heated water, and these gases will be discharged into the infiltration chamber 120 together with the water vapor through the exhaust pipe 109 and the ring pipe 113, and these harmful gases will be guided back to the infiltration link for further treatment. At the same time, the addition of these gases can supplement the pressure inside the infiltration chamber 120 that is reduced due to the infiltration of some water, thereby avoiding a decrease in the infiltration filtration speed, which is beneficial to actual use. The heated and disinfected water is discharged through the drain port 111, and the drain port 111 and the valve body inside the partition plate 114 and the heating rack 119 are all opened at intervals to achieve segmented operation.

In the process of treating the waste acid sewage, people The servo motor 103 can be started, and the servo motor 103 can drive the rotating shaft 125 to rotate clockwise. When the rotating shaft 125 rotates, the inner cylinder 123 can be driven to rotate synchronously through the connecting frame 126. The inner edge of the limiting opening can be used to resist the limiting block 129 and the limiting block 2 132 through the limiting ring 124 and the limiting ring 2 133, so that the inner cylinder 123 can drive the outer cylinder 128 to rotate synchronously. At this time, the through hole 127 on the outer cylinder 128 and the through hole 2 131 on the inner cylinder 123 are in a misaligned state, so that the inner cylinder 123 is in a closed state at this time. In this process, the guide plate 130 and the top ring 135 on the inner side of the inner cylinder 123 are driven by the friction force of the annular groove 136 and the guide ring 137 to rotate with the inner cylinder 123. The guide plate 130 can fully stir the sewage and the reagent inside the inner cylinder 123 through the guide plate 130, so that the waste acid sewage can fully react with the treatment reagent under high-speed rotation, and the reaction and precipitation rate are accelerated. When the preset reaction time is up, the servo motor 103 will stop rotating. When the inner cylinder 123 and the rotating shaft 125 stop rotating synchronously, the top ring 135 and the guide plate 130 will rotate relative to the guide ring 137 under the action of inertia. When the top ring 135 and the guide plate 130 continue to rotate, the guide plate 130 will clean the inner wall of the inner cylinder 123 when it rotates, and scrape off the reacted precipitate attached to the inner wall of the inner cylinder 123, so that the precipitate can fall to the bottom of the inner cylinder 123, and the contact piece 1 at the bottom of the guide plate 130 40 will continuously contact with the top column 139 on the bottom connecting frame 126, and the contact piece 140 will be moved through the collision contact between the top column 139 and the contact piece 140. The vibration generated when the contact piece 140 is moved will be transmitted to the guide plate 130. Through the continuous vibration of the guide plate 130, the sediment attached to the guide plate 130 can be shaken off as much as possible to reduce the residue, which is beneficial to the discharge of sediment and impurities. During the reaction process, when the rotating shaft 125 rotates, the soft rubber disk 142 and the fixed sleeve 122 will be driven by the rotating shaft 125 to rotate, but under the action of gravity and sewage resistance, the soft rubber disk 142 and the fixed sleeve 122 will form a speed difference with the rotating shaft 125, so that the fixed sleeve 122 will form a relative motion with the rotating shaft 125.The reciprocating threaded section 143 on the rotating shaft 125 will guide the fixed sleeve 122 when the fixed sleeve 122 rotates relatively on the outer periphery of the rotating shaft 125, so that the fixed sleeve 122 can drive the soft rubber disk 142 to move up and down on the outer periphery of the rotating shaft 125, so as to fully spread the sewage and medicine inside the inner cylinder 123. The upper and lower soft rubber disks 142 will continuously perform "opening and closing" movements. When the soft rubber disks 142 are "closed", the sewage between the soft rubber disks 142 will be discharged through the perforations 141 and the empty holes 145 respectively under the pressure of the soft rubber disks 142 to form a "jet". The inner wall of the inner cylinder 123 can be impacted by the "jet", so as to prevent the compounds and precipitates at the reaction site from adhering to the inner wall of the inner cylinder 123 for a long time to form solid scale. When the soft rubber disk 1 42 "separated", part of the sewage will pass through the perforations 141 and the empty holes 145 to form a "disturbance", which can further stir and disperse the sewage and the treatment agent, accelerate the reaction process, and is beneficial to practical use. After the servo motor 103 stops rotating, it is left to stand for a period of time to facilitate the sediment to sink to the bottom of the inner cylinder 123. Then the servo motor 103 works again and reverses. At this time, under the action of gravity and inertia, the outer cylinder 128 will be misaligned with the inner cylinder 123. The limiting opening of the limiting ring 124 and the limiting ring 2 133 can limit the limiting block 129 and the limiting block 2 132, so that the limiting block 129 and the limiting block 2 132 are against the inner edge of the other side of the limiting opening. At this time, the outer cylinder 128 on the outer cylinder 128 is dislocated. 28 and the second through hole 131 on the inner cylinder 123 are in a coincident state. At this time, the treated sewage in the inner cylinder 123 will be discharged through the second through hole 131 and the first through hole 127, and enter the middle cavity between the outer side of the outer cylinder 128 and the partition frame 118. Through the reverse rotation of the servo motor 103, the inner cylinder 123 and the outer cylinder 128 are driven to rotate counterclockwise rapidly, so that the internal sewage can be quickly centrifuged and thrown out. After that, the servo motor 103 rotates clockwise again, and the outer cylinder 128 is driven to deflect by gravity and inertia, so that the inner cylinder 123 and the outer cylinder 128 are closed again, which is convenient for the next sewage treatment. When the sewage is introduced into the middle cavity, the valve body inside the downflow port 134 is opened, and the compounds and sediments at the reaction site are discharged from the sewage treatment through the sewage discharge pipe 112 The sewage is discharged from the inner cylinder 123 and then enters the osmosis chamber 120 through the connecting hole 115 at the bottom of the middle cavity. The reverse osmosis membrane 116 at the bottom of the osmosis chamber 120 can filter the sewage and intercept the remaining fine impurities in the sewage. The water is introduced into the upper part of the partition plate 114 and the discharge port 121 on the partition plate 114 can introduce the water into the bottom of the sewage treatment barrel 1. The treated water can be heated and disinfected by the heating rack 119 to achieve full treatment of the water. In the process of heating and disinfection, some harmful gases will be released by the heated water, and these gases will be discharged into the osmosis chamber 120 together with the water vapor through the exhaust pipe 109 and the ring pipe 113.This part of harmful gas is led back to the infiltration link for further treatment. At the same time, the addition of this part of gas can supplement the pressure inside the infiltration chamber 120 that is reduced due to the infiltration of part of the water, avoiding the decrease in the infiltration filtration speed, which is beneficial to practical use. The water that has been heated and disinfected is discharged through the drain port 111. The drain port 111 and the valve body and heating rack 119 inside the partition plate 114 are all opened at intervals to achieve segmented work, which is beneficial to practical use. There are eight infiltration chambers 120, four of which are divided into working areas and rest areas. The working areas and rest areas are alternately distributed. After the sewage treatment barrel 1 has worked for a period of time, people can control the rotating frame 117 and the partition frame 118 to rotate, and rotate the rotating frame 117 and the partition frame 118 by one partition. At the same time, by changing the working state of the valve body inside the connecting hole 115, the switching between the working area and the rest area is realized, so that people can replace the reverse osmosis membrane 116 in the original working area through the inspection port 108 without affecting the work of the sewage treatment barrel 1, and at the same time, the impurities filtered off the reverse osmosis membrane 116 can be processed, which is beneficial to the actual treatment of waste acid sewage.
