Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to an environmentally friendly treatment device and method for wastewater from a steel mill. Background Art

[0002] Steel mill wastewater refers to various water pollutants generated in the steel production process, including production cooling water, flushing water, equipment cleaning water, and wastewater containing chemicals and heavy metals. If the wastewater is discharged directly, it will have a serious impact on the environment, especially the pollution of water bodies. Therefore, environmental protection treatment equipment is needed to treat these wastewaters.

[0003] There are many kinds of existing treatment equipment, and different treatment equipment treats different components, including those for treating particulate impurities, those for treating pH, and those for treating heavy metal content. For example, announcement number CN113336307B discloses a feeding device for a reducing sewage treatment agent, which includes a mounting plate, a liquid storage tank is fixedly connected to one side wall of the mounting plate, two baffles are slidably connected in the liquid storage tank, a U-shaped plate is fixedly connected to one side wall of the two baffles away from each other, a sealing piston is provided between the two baffles, and the sealing piston includes a top cover.

[0004] The feeding device can automatically discharge a variety of raw material liquids into the sewage treatment tank according to the proportion of ingredients as the sewage level rises, and automatically mix the sewage by impact and convection when entering the sewage treatment tank, thereby eliminating the need for pre-mixing, thereby significantly improving the efficiency of sewage treatment and preventing the reduction of reducing properties caused by oxidation of reducing sewage treatment agents due to poor storage.

[0005] However, when the feeding device is neutralizing the pH of sewage, the feeding method is single-point feeding. The fed reducing material is mixed with the sewage in the pool through impact and convection. If the sewage pool is large, the diffusion rate of the reducing material in the sewage is slow, resulting in low neutralization efficiency. At the same time, the sewage far away from the reducing material discharge port has basically no fluidity, or has very slow fluidity. The sewage there needs to rely on the osmotic difference caused by the pH difference to absorb the reducing material, and the requirement for the osmotic difference is relatively large. This will result in excessive reducing material near the discharge port, resulting in excessive reduction of the sewage at the discharge port, which will cause the sewage to deteriorate in the opposite direction.

[0006] Therefore, a new type of steel mill wastewater environmental protection treatment device and method can be used to solve the shortcomings of the prior art. Summary of the invention

[0030] 2. In the process of neutralizing the pH value of sewage, the environmental protection treatment device for wastewater in the steel plant sprays reducing materials into the sewage by setting an inclined nozzle. The sprayed reducing materials are in the shape of wings and have a large spraying area. At the same time, the direction of spraying can be adjusted by the steering component to further expand the spraying area. At the same time, the spraying pressure can be adjusted according to the size of the water body, thereby adjusting the wing area, so as to achieve the best neutralization pH value adjustment.

[0031] 3. In the process of neutralizing the pH value of sewage, the environmental protection treatment device for wastewater in the steel plant sets a baffle assembly to offset the thrust and steering force generated by the nozzle when spraying, so as to avoid the influence of the spraying reducing material on the carrier part and ensure the smooth movement of the carrier part in the sewage. In addition, the vibration plate 1 and the vibration plate 2 inside the baffle assembly will vibrate under the reaction force of the sewage, and the vibration will accelerate the diffusion of the reducing material, thereby further improving the neutralization efficiency.

[0032] In summary, the present invention adopts a mobile feeding method to perform sewage pH neutralization operation, and the neutralization efficiency is higher. During the neutralization process, the intensity, area and neutralization residence time of the reducing material spraying can be adjusted according to the size of the water body to avoid the occurrence of reverse neutralization.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Example 1: Reference Figure 1-Figure 4 A steel mill wastewater environmental protection treatment device includes a carrier part, a reducing material processing part installed on the upper part of the carrier component, and a spreading part installed on the reducing material processing part.

[0056] The carrier part floats on the sewage surface by utilizing buoyancy and can move freely in the sewage to carry out the delivery of mobile reducing materials and expand the feeding area. The carrier part includes a suspension component and a driving component.

[0057] The suspension assembly includes two pontoons 1, and a plurality of legs 2 are fixedly installed at the bottom of the two pontoons 1. A bracket 4 is fixedly installed between two adjacent pontoons 1. The bracket 4 is detachable and fixedly connected to the pontoons 1 by bolts. The pontoons 1 are made of metal material and are hollow in the middle, so that the buoyancy is greater.

[0058] The driving assembly includes a propeller 3 fixedly mounted on the bottom of two floating boats 1, the bottoms of the two propellers 3 are higher than the bottoms of the corresponding legs 2, a waterproof motor 12 is fixedly mounted in the middle of the bracket 4, and a steering paddle 13 is fixedly mounted on the driving end of the motor 12.

[0059] The purpose of setting the legs 2 here is to support the floating boat 1 for placement on land. The purpose of the size design here is to ensure that the propeller 3 does not contact the ground when the device is placed on the road surface, so as to protect the propeller 3; the propeller 3 is an existing propulsion device, which is not elaborated here. The thrust generated by the propeller 3 will drive the floating boat 1 to move. Since the propulsion direction of the propeller 3 is fixed, and the floating boat 1 needs to turn in the sewage, it is necessary to drive the steering paddle 13 to rotate through the waterproof motor 2 12. When the steering paddle 13 rotates, it will increase the resistance between the steering paddle 13 and the sewage, thereby deflecting the floating boat 1 to complete the steering operation.

[0060] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 2 , Figure 5-Figure 7 The reducing material processing section is used for proportioning and mixing the reducing materials. The reducing material processing section includes a material storage component and a pumping component. The material storage component is used for storing the reducing materials, and the pumping component is used for pumping the reducing materials.

[0061] The material storage assembly includes a storage cabinet 5 fixedly mounted on a bracket 4, in which a material storage barrel 1 6 and a material storage barrel 2 7 are fixedly mounted, and heating wires are fixedly mounted inside the material storage barrel 1 6 and the material storage barrel 2 7.

[0062] The reducing material is composed of water and liquid reducing agent. Water is used to dilute the reducing agent to ensure that the concentration of the reducing agent put into the sewage is appropriate to avoid excessive concentration leading to over-reduction.

[0063] The reducing agent is stored in the storage barrel 1 6, and the water is stored in the storage barrel 2 7. The heating wire is provided to heat the reducing agent and the water appropriately so that the reducing agent can reach the best activity, thereby improving the neutralization efficiency of the reducing agent.

[0064] A motor 8 is fixedly installed on the top of the storage barrel 6, and the driving end of the motor 8 extends into the storage barrel 6. A stirring blade is fixedly installed on the driving end of the motor 8. Since the reducing agent is a mixture of multiple materials, a certain degree of precipitation will occur during storage. At this time, the stirring blade is driven by the motor 8 to rotate to stir and mix the reducing agent in the storage barrel 6, thereby reducing the probability of precipitation and ensuring the reduction performance of the reducing agent.

[0065] The pumping assembly includes two pumps 14 fixedly installed inside the storage cabinet 5. The two pumps 14 are connected to the corresponding storage barrel 1 6 and storage barrel 2 7. A discharge pipe 11 is commonly connected between the two pumps 14. The discharge pipe 11 has two feed ports, one discharge port and two pressure regulating ports. A pressure sensor 19 is fixedly installed on the two pressure regulating ports of the discharge pipe 11.

[0066] The two pumps 14 will pump the reducing agent in the corresponding storage tank 1 6 and the water in the storage tank 2 7 to the discharge pipe 11. The purpose of setting the pressure sensor 19 on the discharge pipe 11 is to adjust the pumping force of the pump 14 according to the pressure of the pressure sensor 19. Figure 7 As shown, the discharge pipe 11 is provided with a corner at the position of the pressure sensor 19, and the discharge pipe 11 is not straight, so part of the reducing material in the discharge pipe 11 will first contact the pressure sensor 19, and then return and be discharged from the discharge port, so that a reflux can be formed in the discharge pipe 11 for mixing the reducing agent and water. The pumping force of the pump 14 can be controlled by the pressure sensor 19, thereby controlling the movement speed of the reducing material in the discharge pipe 11. Selecting the optimal movement speed can effectively improve the mixing efficiency of the reducing agent and water.

[0067] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 1-Figure 2 , Figure 7-Figure 19 The spreading part is used to spray the reducing material to different positions in the sewage and spray with different pressures according to different depths. The spreading part includes a spraying component and a steering component.

[0068] The spray assembly includes a telescopic tube 21 fixedly installed at the discharge port of the discharge pipe 11, a limit sleeve 17 fixedly installed on the telescopic tube 21, a discharge hole 1 connected to the telescopic tube 21 is provided on the limit sleeve 17, a docking box 22 is slidably installed on the limit sleeve 17, a discharge hole 2 matched with the discharge hole 1 is provided on the docking box 22, a distribution box 9 is fixedly connected to the docking box 22, a plurality of nozzles 20 with different inclination angles are fixedly installed on the distribution box 9, and a plurality of superchargers matched with the corresponding nozzles 20 are fixedly installed inside the distribution box 9, and a plurality of baffle assemblies 10 are installed outside the distribution box 9;

[0069] The two sides of the limiting sleeve 17 are provided with protrusions, and the side walls of the docking box 22 are provided with grooves matching with the protrusions, so that the docking box 22 will not deviate when sliding up and down on the limiting sleeve 17, and the docking box 22 can be kept vertical.

[0070] The reducing material will enter the telescopic tube 21 from the discharge pipe 11, and then enter the limiting sleeve 17 from the discharge hole 1 through the telescopic tube 21. Before the reducing material enters the docking box 22, the docking box 22 needs to be moved to the bottom so that the discharge hole 2 is aligned with the discharge hole 1. At this time, the reducing material will enter the docking box 22 through the discharge hole 2, and then enter the distribution box 9 to fill the distribution box 9, and then the reducing material will be sprayed into the sewage through the nozzle 20 on the distribution box 9.

[0071] The function of the supercharger is to pressurize the reducing material entering the nozzle 20, so that the reducing material sprayed by the nozzle 20 has a faster speed and a longer range, so that the spraying area is larger and the spraying efficiency is higher.

[0072] A first motor 15 is fixedly installed on the top of the docking box 22, and a gear 1 is fixedly installed on the driving end of the first motor 15. A screw rod 16 is rotatably installed on both sides of the docking box 22. The spiral directions of the two screw rods 16 are the same. A gear 2 meshing with gear 1 is fixedly installed on the two screw rods 16. A hollow fixed block 23 is fixedly installed on both sides of the limit sleeve 17, and a nut rotatably connected to the corresponding screw rod 16 is fixedly installed on the two fixed blocks 23.

[0073] The driving end of the first motor 15 rotates to drive the gear 1 fixedly connected to it to rotate, and the rotation of the gear 1 drives the two gears 2 meshing with it to rotate, and the rotation of the two gears 2 drives the screw rod 16 fixedly connected to the corresponding gear 2 to rotate. Since the screw rod 16 and the docking box 22 are rotatably connected, and the nut and the limiting sleeve 17 are fixedly connected, the screw rod 16 rotates and moves on the nut under the action of the nut, thereby driving the docking box 22 and the distribution box 9 to move on the limiting sleeve 17, thereby realizing the lifting of the distribution box 9;

[0074] The purpose of using a liftable material distribution box 9 is to insert the material distribution box 9 into the sewage when in use, and to move the material distribution box 9 to the top when not in use, so as to prevent the material distribution box 9 from contacting the ground and protect the material distribution box 9.

[0075] The baffle assembly 10 includes a rotating block 29 rotatably mounted on the side of the material distribution box 9, the rotating block 29 and the material distribution box 9 are locked by bolts, a baffle plate 34 is fixedly mounted on the rotating block 29, a groove body 30 is opened inside the baffle plate 34, a vibration plate 32 is fixedly mounted on the baffle plate 34, the vibration plate 32 is located inside the groove body 30, and a water inlet hole 31 matching with the vibration plate 32 is opened on the baffle plate 34;

[0076] A plurality of vibration plates 2 33 are fixedly mounted on one side of the baffle plate 34, and two adjacent vibration plates 2 33 are connected by a chain link 37, and each chain link 37 is rotationally connected to the corresponding vibration plate 2 33. A push plate 35 is fixedly mounted on the vibration plate 1 32, and a push block 36 that cooperates with the push plate 35 is fixedly mounted on one of the vibration plates 2 33.

[0077] Since the angle of each nozzle 20 is different, when the nozzle 20 sprays the reducing material, there will be an impact force on the sewage, and this force in turn acts on the nozzle 20 to generate a reaction force, which will push the nozzle 20 to move, thereby accelerating the movement of the carrier part, and the thrust generated by the nozzle 20 located at the bottom with a larger inclination will cause the carrier part to tilt forward. After the inclination, the uppermost nozzle 20 may be exposed to the water surface, and the spraying may be insufficient due to the excessive movement speed. In order to reduce the impact of the reaction force on the spraying, the angle of the baffle plate 34 can be changed at this time, so that the baffle plate 34 is perpendicular to the thrust direction generated when the nozzle 20 sprays the reducing material. At this time, the baffle plate 34 will have a tendency to move along the thrust direction, and the baffle plate 34 is perpendicular to the thrust direction, so the contact area between the baffle plate 34 and the sewage is increased, and the resistance is increased, which can be used to offset the thrust, which can effectively avoid the above situation.

[0078] A vibration plate 32 and a water inlet 31 are arranged in the baffle plate 34. As the baffle plate 34 moves in the sewage, sewage will enter the water inlet 31, and the sewage will flow out along the vibration plate 32. The sewage entering the water inlet 31 will impact the vibration plate 32 to make the vibration plate 32 vibrate. The vibration of the vibration plate 32 will generate lateral vibration waves in the sewage water area around the vibration plate 32, thereby accelerating the lateral diffusion of the reducing material.

[0079] At the same time, the vibration of the vibration plate 1 32 will drive the push plate 35 to vibrate, and then the vibration plate 2 33 fixedly connected to the push block 36 will be driven to vibrate through the push block 36. Under the action of the chain link 37, all the vibration plates 2 33 will be driven to vibrate at the same time. The vibration of the vibration plate 2 33 will generate a vibration wave perpendicular to the baffle plate 34, so that the reducing material will diffuse faster in the direction perpendicular to the baffle plate 34 (the vibration plate 1 32 and the vibration plate 2 33 are both made of metal thin plates with a certain toughness, and they will be deformed when subjected to impact force).

[0080] The steering assembly includes a fixed ring 26 fixedly mounted on the discharge pipe 11, on which a mounting ring 27 and an arc sleeve 24 are fixedly mounted via a plurality of support rods 28, a pillar is fixedly mounted at the bottom of the limiting sleeve 17, and a sliding connection is formed between the pillar and the arc sleeve 24, a second motor 18 is fixedly mounted on the mounting ring 27, and an arc plate 25 is fixedly mounted on the driving end of the second motor 18, and the arc plate 25 is fixedly connected to the pillar.

[0081] The reducing material sprayed by the above-mentioned nozzle 20 is in the shape of a flat wing. At this time, the spraying area of ​​the reducing material is still limited. At this time, the driving end of the second motor 18 rotates to drive the arc plate 25 to rotate, and drives the limit sleeve 17 to rotate through the support. The limit sleeve 17 drives the dividing box 9, the docking box 22 and the nozzle 20 to rotate. The second motor 18 adopts a reciprocating rotation operation mode, so that the path of the nozzle 20 spraying the reducing material is in the shape of a three-dimensional wing, the spraying area is larger, and the spraying efficiency is higher.

[0082] The arc sleeve 24 here provides support for the limiting sleeve 17 , the docking box 22 , the material distribution box 9 and the nozzle 20 , so as to prevent the gravity of the limiting sleeve 17 , the docking box 22 , the material distribution box 9 and the nozzle 20 from being borne entirely by the driving end of the second motor 18 , thereby protecting the second motor 18 .

[0083] The specific operation steps of this device are as follows:

[0084] First, place the whole device in the sewage, and suspend the device on the surface of the sewage through the carrier suspension component, and then put the two reducing materials with good proportion into the storage component for storage. Before spreading the materials, the reducing materials need to be stirred to prevent precipitation;

[0085] Then, the spraying assembly is extended below the water surface, and then the reducing material is pumped from the material storage assembly to the spraying assembly through the pumping assembly, and the reducing material is sprayed into the sewage through the spraying assembly. The reducing material formed by the spraying is in the shape of a flat wing, and the spraying pressure can be automatically adjusted during the spraying process to change the length of the wing;

[0086] While spraying, the direction of the spray assembly can be adjusted through the steering assembly, so that the spray path of the reduction material in the sewage is three-dimensional wing-shaped, so that the spray path is larger, the reduction effect is better, and the speed is faster;

[0087] After the raw materials are prepared, the entire device is driven by the driving component to move on the sewage surface. The direction can be changed freely during movement, so that spraying and feeding operations can be carried out on various parts of the sewage.

[0088] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
