Description

Technical Field

[0001] This invention relates to the field of mine water treatment technology, specifically a modular high-salinity mine water pretreatment and deep concentration system. Background Technology

[0002] Mine water is wastewater generated during the mining of coal, metal, and non-metal mines due to various factors such as groundwater inflow, production water use, and rainfall runoff. Based on its water quality characteristics, mine water can be classified into types such as mine water containing suspended solids, high-salinity mine water, acidic mine water, and mine water containing heavy metals.

[0003] If high-salinity mine water is discharged directly without effective treatment, it will not only cause salinization of surface water and soil, damaging the ecological environment, but may also threaten the safety of downstream drinking water. Therefore, achieving the resource utilization and compliant discharge of high-salinity mine water has become an urgent need for the sustainable development of mining enterprises.

[0004] Currently, the main technologies for treating high-salinity mine water include physical sedimentation, chemical coagulation, membrane separation (such as ultrafiltration, nanofiltration, and reverse osmosis), and evaporation crystallization. However, existing technologies generally suffer from the following problems: Poor pretreatment effect and serious membrane fouling: The high content of suspended solids, colloids and organic matter in high-salt mine water is difficult to remove effectively by traditional pretreatment processes, resulting in frequent clogging of subsequent membrane systems, short cleaning cycles and high operating costs.

[0005] Low system integration and large footprint: Existing treatment systems are mostly distributed, with redundant equipment, low automation, and difficulty in adapting to the characteristics of large fluctuations in mine water volume and complex water quality.

[0006] Low concentration efficiency and high energy consumption: In the deep concentration stage, traditional reverse osmosis systems are prone to membrane fouling and scaling in high-salt environments, resulting in a decrease in water production rate, a significant increase in energy consumption, and poor economic efficiency.

[0007] Lack of modular design and maintenance difficulties: Most existing systems are customized and lack standardized and modular design, resulting in long installation cycles, inconvenient transportation, and complex maintenance, making it difficult to deploy flexibly in mining areas.

The receiving and draining frame has two scraper strips that are in contact with the outer surface of the filter cylinder. Mine water is injected into the pretreatment chamber through the injection pipe. The surging force of the mine water controls the rotation of the filter cylinder, which, together with the two scraper strips, forms a self-cleaning mechanism for the filter cylinder.

[0013] Preferably, a number of actuating blades are fixedly connected to the outer surface of the top of the filter cylinder, and an annular collection pipe is installed on the top of the sealing plate. A number of drainage pipes are fixedly connected to the bottom of the annular collection pipe.

[0018] Modular design with strong adaptability: The system adopts a modular design, and each functional module can operate independently or be used in combination. This makes it easy to flexibly adjust the process route according to changes in mine water quality and quantity, adapt to the complex and ever-changing water quality conditions in different mining areas, and facilitates transportation, installation and maintenance.

[0019] Self-cleaning function, stable and reliable operation: The filter cartridge rotates by the power of water flow, which, together with the scraper strips and pulse jet unit, forms an efficient self-cleaning mechanism, effectively preventing filter membrane clogging, extending the service life of the membrane module, reducing the frequency of manual cleaning and maintenance costs, and ensuring long-term stable operation of the system.

[0020] Significant benefits in resource recycling and environmental protection: Through the deep concentration treatment of high-salt mine water, not only can water resources be effectively recycled and reused, reducing the impact of mine water discharge on the environment, but the concentrated salts can also be further utilized as resources, achieving a win-win situation for both environmental and economic benefits.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: See attached document Figures 1 to 10 A modular high-salinity mine water pretreatment and deep concentration system, comprising: Pretreatment module 100 is used for preliminary sand removal and sedimentation treatment of mine water; The intelligent integrated processing module 200 is connected to the output end of the preprocessing module 100; The intelligent integrated processing module 200 includes a filtration unit 300 and a deep concentration unit 400 connected to the output end of the filtration unit 300. The filter unit 300 is used to efficiently filter mine water using a special inorganic membrane to remove suspended solids, organic matter and some ions from the mine water; The deep concentration unit 400 uses reverse osmosis membrane technology to deeply concentrate the filtered mine water, reducing the conductivity and salinity of the effluent. The control module adopts a PLC automatic control system to realize remote monitoring and automatic operation of the entire system. The control module has local and remote dual control modes, supports unattended operation, and has fault alarm, automatic cleaning, data recording and uploading functions. To save land, this invention is constructed underground, which can save the land needed to build mine water treatment plants on the surface.

[0025] The pretreatment module 100 includes a cyclone sand separator and a pre-sedimentation tank; The hydrocyclone sand separator is used to remove sand particles with a diameter ≥0.1mm, and the separated sand particles are directly discharged into the sludge concentrate tank. The pre-sedimentation tank is used to stabilize water quality and quantity. After pre-settling in the underground water tank, the mine water directly enters the intelligent integrated mine water treatment device for efficient separation. The filtered clean water is directly reused (its water quality can be directly used as reverse osmosis water supply), while the sludge enters the sludge treatment system. This project uses an intelligent integrated mine water treatment device and auxiliary equipment, utilizing the filtration characteristics of special inorganic membranes to completely remove suspended solids and most organic matter. The equipment is miniaturized, integrated, and modular, featuring a small total footprint, low operation and maintenance costs, low chemical dosage, and a high degree of intelligence. High filtration precision and separation efficiency: It can retain solid particles larger than nanometers and micrometers.

[0026] High water flux and long service life: Adopting surface pulse disturbance filtration technology to prevent clogging of the filter element surface, stable operation, online cleaning capability, suitable for continuous filtration and concentration filtration.

[0027] Wide range of applications: It can be used for media filtration under various harsh working conditions such as high temperature, high pressure, acid and alkali and organic solvents.

[0028] By employing a combined process of equalization tank + flocculation sedimentation + high-density sedimentation, suspended solids, colloids, and some hardness are removed. By employing a dual-membrane process of "ultrafiltration + reverse osmosis", preliminary desalination and concentration are achieved.

[0029] See attached document Figures 2 to 10 The intelligent integrated processing module 200 also includes a housing 201. The interior of the housing 201 is divided into a pretreatment chamber and a filtration chamber by a partition plate 202. A drainage channel for draining the mine water inside the pretreatment chamber to the filtration chamber is provided above the partition plate 202. An injection pipe 203 for injecting mine water into the pretreatment chamber is fixedly connected to the housing 201. The partition plate 202 is fixed inside the housing 201 to divide the internal space of the housing 201 into two parts, with the left side being the pretreatment chamber and the right side being the filtration chamber, for different purification treatments of mine water. The pretreatment chamber is equipped with a treatment unit 500 for preliminary treatment of mine water that has undergone initial sand removal and sedimentation. The processing unit 500 is used to treat suspended solids and other organic impurities in the mine water pretreated by the pretreatment module 100, which not only reduces the workload of the filtration unit 300, but also further improves its mine water treatment effect. The filtration unit 300 includes a membrane separation component and a pulse gradient perturbation component disposed inside the filtration chamber; The membrane separation module is used to filter the pretreated mine water to remove suspended solids and other organic matter. The pulse gradient disturbance module agitates the inorganic membrane of the membrane separation module to form a self-cleaning mechanism. It should be noted that the membrane separation unit uses a special inorganic membrane with strong acid and alkali resistance and can operate under large cross-flow conditions. The pulse gradient disturbance unit consists of a pneumatic diaphragm pump and pipelines.

[0030] The deep concentration unit 400 includes a reverse osmosis membrane module for concentrating high-salinity mine water, and the input end of the reverse osmosis membrane module is connected to the outlet end of the membrane separation module. It should be noted here that the reverse osmosis membrane module uses the existing technology for concentrating high-salinity water. It concentrates the filtered high-salinity mine water through the principle of reverse osmosis, thereby improving the subsequent water resource recycling effect.

[0031] See attached document Figure 3 and Figure 4 A sealing plate 204 is fixedly connected inside the pretreatment chamber, and a material receiving and sewage discharge rack 205 is fixedly connected to the bottom of the pretreatment chamber. It should be noted here that the receiving and draining rack 205 consists of a receiving hopper and a drain pipe, and is used to periodically remove the debris that has settled at the bottom; The processing unit 500 includes a filter cartridge 501 rotatably connected inside the sealing plate 204, and the top of the filter cartridge 501 is open. By setting the filter cartridge 501 in the processing unit 500, the mine water entering the pretreatment chamber can be filtered to remove large particulate suspended solids, organic matter and some ions from the mine water after preliminary sand removal and sedimentation treatment, thereby reducing the workload of the filter unit 300. The receiving and discharging rack 205 has two scraper strips 502 that are in contact with the outer surface of the filter cylinder 501. Mine water is injected into the pretreatment chamber through the injection pipe 203. The surging force of the mine water controls the rotation of the filter cylinder 501, which, together with the two scraper strips 502, forms the self-cleaning of the filter cylinder 501. The scraper strip 502 is designed to clean the filter surface of the filter cartridge 501 when the filter cartridge 501 rotates, thus preventing the accumulation of adhering substances on the outer surface of the filter cartridge 501 and reducing its filtration performance. It has a self-cleaning function and does not require shutdown, thus improving the orderliness of water treatment.

[0032] See attached document Figure 4 and Figure 8 The outer surface of the top of the filter cartridge 501 is fixedly connected with several actuating blades 503. The top of the sealing plate 204 is equipped with an annular collection pipe 504, and the bottom of the annular collection pipe 504 is fixedly connected to several drainage pipes. The bottom ends of the drainage pipes extend to the bottom of the sealing plate 204 and are fixedly connected to a water spray hood 505. The spray outlets of the water spray hoods 505 are all tilted and aligned with the actuating blades 503. When the mine water injected into the injection pipe 203 is pressurized and discharged into the annular collection pipe 504, the water inside the annular collection pipe 504 can be sprayed out at an angle through several water spray nozzles 505. Since the nozzles of several water spray nozzles 505 are all tilted and aligned with several actuating blades 503, the surging force of the sprayed water can actuate several actuating blades 503, thus causing the filter cartridge 501 to rotate, forming the self-cleaning operation of the filter cartridge 501. A diversion pipe 506 is fixedly connected between the injection pipe 203 and the annular collection pipe 504, and a valve control component is provided between the diversion pipe 506 and the injection pipe 203.

[0033] By fixing a branch pipe 506 between the injection pipe 203 and the annular collection pipe 504, the water source inside the injection pipe 203 can enter the annular collection pipe 504 through the branch pipe 506. It should be noted here that the valve control components may include two electric switching valves and a pressure gauge. The pressure gauge detects the water pressure inside the injection pipe 203. The two electric switching valves are installed at the bottom of the injection pipe 203 and the end of the diversion pipe 506. Thus, by opening one of the electric switching valves, the injection direction of the injection pipe 203 can be changed, thereby selectively driving the rotation of the filter cartridge 501.

[0034] Example 2: The difference from Example 1 is that; See attached document Figure 5 The valve control components include an annular plate 507 and a permeable plate 508 fixed inside the diversion pipe 506. A sealing plate 509 for sealing the opening of the annular plate 507 is fixedly connected to one side of the permeable plate 508 by a spring. When the outer surface of the filter cartridge 501 is covered with debris, which seriously affects its filtration effect, the water pressure under its sealing plate 204 will gradually increase, thus simultaneously increasing the pressure of its injection pipe 203. The increased pressure inside the injection pipe 203 will squeeze the sealing plate 509, causing it to contract. This will control the water source inside the injection pipe 203 to directly enter the annular collection pipe 504 through the diversion pipe 506, and finally spray it out through several water spray nozzles 505, forming the self-rotation control of the filter cartridge 501. Finally, it can work with the scraper strip 502 to perform self-cleaning.

[0035] Example 3: The difference from Example 1 is that; See attached document Figure 4 and Figure 6 The filter cartridge 501 is equipped with a pulse impact unit 600; the pulse impact unit 600 is used to pulse impact the filter surface of the filter cartridge 501 from the inside to the outside, and to work with the scraper strip 502 to separate the filter residue that is knocked off by the pulse impact in a timely manner. The rotation of the filter cartridge 501 can be used in conjunction with the scraper strip 502 to clean the filter surface on its outer surface. It can also be used in conjunction with the pulse jet unit 600 to perform pulse flushing on the area cleaned by the scraper strip 502, thereby further improving the filtration intensity of the scraper strip 502 on the filter cartridge 501.

[0036] The pulse unit 600 includes an air pump 601 disposed above the housing 201 and a pulse pipeline disposed inside the filter cartridge 501; by injecting pulse gas into the pulse pipeline through the air pump 601, the filter cartridge 501 can be pulsed and disturbed. The air pump 601 is connected to an external power source and control switch to inject gas into the pulse line. By injecting gas, the pulse line can be controlled to perform pulse flushing on the filter surface of the filter cartridge 501, thereby improving the self-cleaning effect of the filter cartridge 501. The pulse pipeline includes an inflation pipe 602 fixed to the top of the housing 201 and connected to the air outlet of the air pump 601. The bottom end of the inflation pipe 602 extends into the interior of the filter cartridge 501. A compression storage chamber is provided at the bottom of the inflation pipe 602. A circular control housing 603 is fixedly connected to the bottom of the inflation pipe 602. Pulse nozzles 604 are fixedly connected to both sides of the top of the circular control housing 603. The two pulse nozzles 604 correspond to the two scraper strips 502 respectively. When gas is continuously injected into the air pipe 602 by the air pump 601, the gas inside the air pipe 602 will be ejected through the two pulse nozzles 604, thus forming a pulse flushing operation. Two pulse nozzles 604 are respectively matched with two scraper strips 502, so that after the pulse nozzles 604 pulse-impact the filter surface of the filter cylinder 501, the scraper strips 502 can wash the filter surface after the impact, forming a rapid separation of filter cake and preventing it from adhering again. The circular control housing 603 has a hollow control disk 605 inside, and the top outer edge of the hollow control disk 605 is used to block the injection ends of the two pulse nozzles 604. Two air injection holes 606 are opened on the top outer edge of the hollow control disk 605. The inner bottom of the filter cylinder 501 is fixedly connected to a fixed shaft 607, and the fixed shaft 607 extends into the interior of the circular control housing 603 and is fixedly connected to the hollow control disk 605. The filter cartridge 501 is fixedly connected to the fixed shaft 607, and the fixed shaft 607 is fixedly connected to the hollow control disk 605, so that when the filter cartridge 501 rotates, the fixed shaft 607 can drive the hollow control disk 605 to rotate, thereby forming a pulse switching operation. By sealing the injection ends of the two pulse nozzles 604 with the top outer edge of the hollow control disk 605, the gas inside the air filling pipe 602 cannot be discharged, thus performing air pressure storage work inside the compression storage chamber. When the hollow control disk 605 rotates to the point where the two air injection holes 606 coincide with the injection ends of the two pulse nozzles 604, the compressed gas inside the compression storage chamber can be rapidly released, thereby forming pulse impact work.

[0037] When the filter cartridge 501 rotates at a higher speed, it indicates a higher water pressure, and thus a higher pulse frequency. Conversely, when the filter cartridge 501 rotates at a lower speed, it indicates a lower water pressure, and thus a lower pulse frequency. The pulse frequency is matched with the rotation speed of the filter cartridge 501, making it suitable for self-cleaning under different water pressure and flow conditions.

[0038] Finally, it should be noted that the above are merely 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
