Description

Technical Field

[0001] The invention relates to the technical field of pollutant treatment, and in particular to a polluted water conveying and metering treatment system for supercritical water treatment. Background Art

[0002] Supercritical water (referring to water in a special state with a temperature and pressure higher than 374.15℃ and 22.12MPa respectively) is a special state of water with excellent solubility and oxidizability. It can effectively decompose and remove various pollutants in water, including organic matter, inorganic matter, heavy metal ions, etc.; the supercritical water oxidation treatment system utilizes the unique properties of supercritical water (conditions where both the temperature and pressure are higher than its critical point) and can treat various pollutants, such as industrial wastewater, domestic sewage, sludge, sediment, organic matter, etc.

[0003] The metering accuracy and stability of the feed of the industrial-grade supercritical water oxidation treatment system are closely related to the supercritical water oxidation treatment effect; (In this application, "polluted water" is used as a general term for low-viscosity fluids such as industrial wastewater and high-viscosity fluids such as sludge) In the prior art, materials (polluted water) of different viscosities require different transportation and metering methods, and the amount that can be processed per unit time is also different; for low-viscosity fluids, a pump body is sufficient to meet the transportation and metering requirements; but for high-viscosity fluids (10000cp-15000cp and above), it is difficult to achieve smooth transportation through conventional transportation methods, so high-viscosity material conveyors are generally used for transportation; however, the high viscosity characteristics of the material will also cause the material to adhere to storage and transportation equipment such as material storage tanks and conveyors, resulting in extremely inaccurate metering, and too long adhesion time will cause the material to dry out, resulting in transportation jams, and it is difficult to achieve accurate quantitative and long-term stable transportation; the above problems directly lead to the use of supercritical water oxidation technology to treat high-viscosity materials. There are great limitations, which greatly restricts the further promotion of supercritical water oxidation technology.

[0004] In response to the above problems, a Chinese invention patent with announcement number CN110822287B discloses a metering and conveying system and a control method for supercritical water treatment of high-viscosity materials. By setting up multiple secondary buffer bins and secondary conveyors, the conveying capacity of each secondary buffer bin and the corresponding secondary conveyor is greatly reduced, but the total conveying capacity remains unchanged. Therefore, the amount of material adhering to the secondary buffer bin and the secondary conveyor can be evenly distributed to each conveyor with higher precision, which greatly reduces the amount of material adhesion on each secondary buffer bin and the corresponding secondary conveyor. Even if the material dries up during long-term operation, it is not easy to cause jamming due to the small amount of material conveyed. When the total conveying amount remains unchanged, the conveying capacity in each secondary system is reduced, so that conveying equipment with a smaller rated conveying capacity and higher precision can be used. Under the same required conveying capacity, the overall error of the system is reduced and the conveying accuracy is improved.

[0005] Although the above scheme has achieved long-term continuous transportation to a certain extent and improved the adaptability of the supercritical water oxidation treatment system to high-viscosity materials, it is still inevitably prone to problems such as material adhesion affecting transportation and accurate material metering due to its own structural limitations, and the problem of material drying causing transportation jams still exists.

[0006] Therefore, there is a need for a contaminated water conveying and metering treatment system for supercritical water treatment, which has an accurate and stable high-viscosity material conveying and metering process, is not easy for the material to dry out on the conveying equipment, and has smooth conveying.

[0077] The delivery pump body 200 is positioned outside the storage tank 100 and is a mud pump.

[0078] The main body of the lifting and pressing plate assembly is in the shape of a horizontal plate, which is slidably positioned in the material storage tank 100. The combination with the material storage tank 100 is essentially a piston structure, which assists the feeding and discharging of the material storage tank 100 when moving up or pressing down;

[0079] The lifting and lowering plate assembly includes a plate 310, a closed ring body 320 and a plate driving assembly 340;

[0080] The pressing plate 310 is a horizontally placed hard circular plate that is lifted and lowered in the storage tank 100; a passage opening 330 is provided on the pressing plate 310, and the passage opening 330 is a vertical through hole that penetrates the pressing plate 310, and an electric valve for controlling its own opening and closing is provided on the passage opening 330, and the electric valve is connected to the control unit signal;

[0081] The closed ring body 320 is a rubber ring, which is sleeved and fixed on the pressing plate 310, coaxial with the pressing plate 310, and the outer ring abuts against the inner wall of the storage tank 100;

[0082] The plate driving assembly 340 is used to drive the pressing plate 310 to move up and down, and is preferably a telescopic cylinder fixed on the storage tank 100 and arranged longitudinally.

[0083] like Figure 3 and Figure 4 As shown, the material conveying assembly is used to quantitatively convey the material in the storage tank 100, and is in the shape of a long strip arranged horizontally, and includes a carrying plate 510, a conveying tube body, a cutting assembly 560 and an extrusion conveying assembly;

[0084] The bearing plate 510 is a long hard plate with a C-shaped longitudinal section and an opening facing downward, which is arranged horizontally, with its end close to the storage tank 100, and plays the role of supporting the fixed end pipe 540, the cutting assembly 560 and the extrusion conveying assembly, and its length is 1.2 to 1.4 times the length of the material conveying pipe 530; the bearing plate 510 is fixed to the ground by a plate bracket 520, and the plate bracket 520 is a rod body, a plate body or a frame structure arranged longitudinally, and there are multiple plates, and the top is fixed to the bottom of the bearing plate 510, and plays the role of supporting the bearing plate 510;

[0085] The conveying tube body serves as a material channel, and its length direction is the same as that of the carrying plate 510. The position near its end is fixed on the carrying plate 510, and is suspended, and one end is connected to the discharge port 130.

[0086] The conveying pipe body includes a material conveying pipe 530 and end pipes 540 fixed at both ends of the material conveying pipe 530;

[0087] The end tube 540 is a hard tube body with a length less than 20 cm. The end tube 540 is fixed to the support plate 510 through a hard rod body or a hard plate body fixed to its outer side wall. One end of the end tube 540 is fixed to the discharge port 130 and communicates with the internal space of the storage tank 100.

[0088] The material conveying pipe 530 is a hose made of metal or rubber, and its two ends are respectively fixed to the end edges of the two end pipes 540; due to being fixed to the edge of the end pipe 540, the end of the material conveying pipe 530 is circular; when the material conveying pipe 530 is not squeezed by internal and external pressures, the longitudinal section at a position far from its own end is fusiform; when the storage tank 100 outputs materials under extrusion, the material conveying pipe 530 is gradually stretched and tends to be circular tubular; when being squeezed by the extrusion conveying assembly, the material conveying pipe 530 is gradually pressed and tends to be flat tubular; the length of the material conveying pipe 530 is greater than 3 meters and less than 5 meters;

[0089] The cutting assembly 560 is fixed on the bearing plate 510, located at the end of the bearing plate 510 far from the storage tank 100, and cuts the material that has been output from the conveying pipe body from the material still in the conveying pipe body by means of rotary cutting;

[0090] Further, the cutting assembly 560 includes a motor and a steel wire positioned on the side wall of the output shaft of the motor; when the motor operates, the steel wire continuously rotates and closely adheres to the end of the conveying pipe body to cut the material;

[0091] The extrusion conveying assembly is used to quantitatively discharge the material in the conveying pipe body by squeezing the conveying pipe body to make it quantitatively flattened, is positioned on the bearing plate 510, and includes a top guide rail 571, a closing clamp, and an extrusion displacement assembly;

[0092] The top guide rail 571 is a straight guide rail, fixed to the bottom of the bearing plate 510, and serves as a guide for the movement of the extrusion displacement assembly;

[0093] The closing clamp is an electric clamp, controlled by the control unit to operate, positioned on the bearing plate 510 or the top guide rail 571, and is arranged near the end of the conveying pipe body far from the storage tank 100; normally, the closing clamp clamps the material conveying pipe 530 to make it closed, and when the extrusion displacement assembly moves towards the closing clamp, the closing clamp relaxes;

[0094] The main body of the extrusion displacement assembly is a U-shaped with an opening downward, slidably positioned on the top guide rail 571, and includes a sliding carrier 573, a transverse carrier plate 574, an end plate 575, and a sliding clamping column 576;

[0095] The sliding carrier 573 is slidably positioned on the top guide rail 571,内置电机,在控制单元的控制下沿着顶导轨571移动;

[0096] The transverse carrier plate 574 is a hard plate body arranged horizontally, serving as a guide rail, with its top fixed to the bottom of the sliding carrier 573, and the length direction is perpendicular to the length direction of the top guide rail 571;

[0097] It should be noted that there is an unclear expression "内置电机,在控制单元的控制下沿着顶导轨571移动" in the original text for item . The above translation tries to make sense based on the context, but this part may need further clarification in the original text.The end plate 575 is a hard plate or block, which plays the role of carrying the sliding clamping column 576. There are two of them, which slide along the length direction of the cross-carrying plate 574 under the coordinated control of the control unit and the power assembly;

[0098] The sliding clamping column 576 is a hard column arranged longitudinally, corresponding to the end plate 575 one by one, with the top positioned at the bottom of the end plate 575 and rotating around its own axis; when the end plates 575 slide toward each other, the two sliding clamping columns 576 approach each other.

[0099] Preferably, the structure of the closing clamp is the same as that of the extrusion displacement assembly, and the cylindrical and rotatable sliding clamping column 576 is used as a clamping claw to cause less damage to the material conveying pipe 530.

[0100] Preferably, the end tube 540 is a hard tube body with a shuttle or elliptical cross section arranged vertically.

[0101] The power assembly is used to provide power for the operation of various components of the contaminated water transport and metering treatment system for supercritical water treatment in this application, and the control unit plays a role in controlling the coordinated operation of various components of the contaminated water transport and metering treatment system for supercritical water treatment. Both are prior arts and will not be elaborated here.

[0102] Preferably, the control unit is a combination of a programmable logic controller, a remote controller and control buttons.

[0103] When the polluted water delivery and metering treatment system for supercritical water treatment in this application is in operation:

[0104] If the viscosity of the material (contaminated water) to be metered and processed is low (preferably less than 10,000 cp), the material is directly quantitatively transported to the target location through the delivery pump body 200;

[0105] If the viscosity of the material (contaminated water) to be metered and processed is high (above 10000cp), the material is poured into the storage tank 100 by cooperating with the lifting and lowering plate assembly, and then quantitatively transported to the target location through the discharge port 130 through the material conveying assembly;

[0106] If the material (polluted water) to be metered and processed contains both low-viscosity and high-viscosity components (such as sewage and silt) and the two are not easy to mix into a stable slurry, the material is poured into the storage tank 100 in conjunction with the lifting and lowering plate assembly, and after sedimentation, the material component with lower viscosity is discharged to the space above the pressure plate 310 through the channel port 330, and then the material component with lower viscosity is quantitatively transported to the target position by the conveying pump body 200, and the material component with higher viscosity is quantitatively transported to the target position through the discharge port 130 through the material conveying assembly.

[0107] The following is a detailed description of the treatment process in the state where the material (polluted water) to be metered and treated contains both low-viscosity and high-viscosity components, and the treatment processes in the other two states are not described in detail:

[0108] 1. First, the material to be processed is loaded into the storage tank 100 through the feeding port 110. During the feeding process, the pressure plate 310 is controlled to move up gradually to make room for the material. After the end, it is left to stand for more than 15 minutes to allow most of the materials with high viscosity to settle;

[0109] 2. Open the channel opening 330 and control the pressing plate 310 to move downward, so that most of the materials with lower viscosity are discharged above the pressing plate 310 and then the channel opening 330 is closed;

[0110] 3. Use the delivery pump body 200 to quantitatively discharge the materials above the pressing plate 310 to the target position (the oxidation treatment of materials with different viscosities requires different treatment times and environments, and it is beneficial to improve the treatment efficiency to put the material components with different viscosities into the supercritical water oxidation treatment system at different stages); during this process, the materials with higher viscosity below the pressing plate 310 undergo further precipitation, and at this time, the materials below the pressing plate 310 and located in the upper layer can be discharged for a second time, or they can be discharged together after new materials are loaded and precipitated;

[0111] 4. When the material conveying component is not needed to convey the material (with a high viscosity), the closing clamp clamps and closes the material conveying pipe 530, and the extrusion displacement component is in a static state and does not contact the material conveying pipe 530; the material storage tank 100 fills the material conveying pipe 530 and makes it round under the action of pressure and its own gravity;

[0112] 5.
