Description

Technical Field

[0001] This invention relates to the field of mine water quality monitoring and treatment technology, specifically to a method for online monitoring and advanced treatment of mine water quality. Background Technology

[0002] Coal production, a crucial component of my country's energy structure, increasingly poses a significant threat to miners' health due to the high concentration of dust generated during its production. During coal mining, large amounts of mine water are readily generated at the mine bottom. After pretreatment, this water is primarily used for dust suppression and coal washing. Furthermore, utilizing treated mine water for efficient spray dust suppression can effectively reduce dust concentration in the working environment, improve the working conditions, reduce occupational diseases such as pneumoconiosis, and protect miners' health. It can also alleviate the environmental conflict between production water and wastewater discharge. Research and analysis of current problems and objective needs in mine water utilization have revealed that mine water contains not only amorphous particles (primarily coal and rock particles) and ultrafine particles (primarily clay minerals), but also large amounts of suspended solids, heavy metal ions, organic matter, and microorganisms. This leads to persistent nozzle blockage during spray dust suppression, resulting in poor dust suppression effectiveness. Therefore, a combination of methods is needed for deep treatment of spray water to ensure long-term stable coal mining and reduce dust dispersion.

[0003] Current research on related technologies mainly includes:

[0004] Application No. 201810054893.6 discloses a water purification treatment device, which includes a box, a metal mesh cover, an activated carbon adsorbent, and a water inlet pipe. A water pump is installed on the water inlet pipe. The device includes a 5-micron PPF filter element, a 1-micron PPF filter element, an RO reverse osmosis membrane, a post-sintered activated carbon adsorption layer, a flocculation box, a flocculant box, a stirring motor, a reducer, a first connecting pipe, a second connecting pipe, a filter press, and a recovery box. The stirring motor is installed on the left outer wall of the flocculation box. A stirring shaft is installed on the right output end of the reducer, and a stirring paddle is installed on the stirring shaft. A diaphragm pump and a first valve are installed on the first connecting pipe, a second valve is installed on the second connecting pipe, and a water outlet pipe is installed on the water outlet pipe, with a third valve installed on the water outlet pipe.

[0005] The aforementioned patent application utilizes a 5-micron PPF filter element, a 1-micron PPF filter element, an RO reverse osmosis membrane, and a post-sintered activated carbon adsorption layer for layer-by-layer filtration and adsorption, ensuring comprehensive adsorption and improving water purification capabilities. However, a technical problem remains: calcium ions in mine water cannot be deeply treated. Furthermore, calcium ions easily form precipitates and deposits, which can clog atomizing nozzles. Simply relying on existing technologies cannot achieve deep treatment of calcium ions.

[0006] This shows that the existing technology needs further improvement. Summary of the Invention

[0007] One of the objectives of this invention is to provide an online monitoring and deep treatment system for mine water quality, which can effectively prevent the technical problem of clogging of atomizing nozzles during subsequent spray dust suppression. This invention can effectively extend the service life of the spray dust suppression system, improve the atomization dust suppression effect at coal mine operation sites, and achieve economical and precise dust suppression.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A mine water quality online monitoring and deep treatment system includes a mine water pretreatment module, a calcified material deep treatment module, a mine water quality monitoring module, a water quality over-limit alarm module, a gas delivery module, and a gas-water two-phase flushing module.

[0010] The aforementioned mine water pretreatment module is used to initially remove particles and organic suspended solids from the mine water;

[0011] The deep treatment module for calcified substances includes an ion exchange resin unit, a water softening unit, and a reverse osmosis filtration unit arranged sequentially along the direction of mine water flow. The mine water, after being pretreated by the mine water pretreatment module, enters the deep treatment module for the initial removal of calcified substances.

[0012] The aforementioned mine water quality monitoring module is used to monitor key indicators of mine water after it has been treated by the calcification material deep treatment module, and to perform real-time data statistics and transmission.

[0013] The aforementioned water quality exceeding limit alarm module is used to monitor markers that cause blockage of the atomizing nozzles;

[0014] The gas delivery module mainly includes a gas generation unit, which is used to deliver gas with a certain pressure to an atomizing nozzle connected to the mine water quality monitoring module to generate a gas-water mixture for atomization dust suppression and to reduce clogging of the atomizing nozzle caused by external dust. When the atomizing nozzle stops working, the gas generation unit delivers gas with a certain pressure to the calcification deep treatment module to perform secondary removal of calcification in the calcification deep treatment module using gas with a certain pressure.

[0015] The gas-water two-phase flushing module is used to flush the pipelines in the deep treatment module for calcified materials.

[0016] The above-mentioned online monitoring and advanced treatment system for mine water quality includes a mine water pretreatment module comprising a raw water centrifugation unit, a particle sedimentation unit, and an activated carbon unit.

[0017] The above-mentioned online monitoring and deep treatment system for mine water quality includes a mine water quality monitoring module comprising a mud particle monitoring unit, a pH monitoring unit, a turbidity monitoring unit, a calcium ion monitoring unit, and a temperature monitoring sensor unit.

[0018] The aforementioned mine water quality online monitoring and deep treatment system includes a water quality over-limit alarm module comprising an audible and visual alarm and an online alarm unit. When the water quality monitoring detects that a marker that is prone to causing nozzle blockage exceeds the standard, the audible and visual alarm will issue an audible and visual alarm and simultaneously transmit the alarm signal to the mine water quality monitoring module online.

[0019] The aforementioned mine water quality online monitoring and deep treatment system includes a gas-water two-phase flushing module comprising a clear water tank, a pipeline flushing pump group, and a wastewater flushing discharge unit. A gas generation unit delivers gas at a certain pressure to the calcification deep treatment module, where it forms a gas-water two-phase mixture with the water supplied by the pipeline flushing pump group, thus performing deep treatment on the calcification. One end of the clear water tank is connected to the calcification deep treatment module, and the other end is connected to the wastewater flushing discharge unit.

[0020] The aforementioned online monitoring and deep treatment system for mine water quality includes a water quality exceeding limit alarm module connected to a monitoring host and a power supply box.

[0021] Another objective of this invention is to provide a method for online monitoring and advanced treatment of mine water quality, which employs the aforementioned online monitoring and advanced treatment system for mine water quality, and includes the following steps:

[0022] Step 1: Mine water enters the mine water pretreatment module and passes through the raw water centrifugation unit, particle sedimentation unit and activated carbon unit in sequence to filter out the coal mud rock composite particles and organic suspended solids in the mine water.

[0023] Step 2: The pretreated mine water enters the calcification deep treatment module, and passes through the ion exchange resin unit, softened water unit, and reverse osmosis filtration unit in sequence to perform preliminary treatment of the calcification, providing clean mine water for the atomizing nozzles;

[0024] Step 3: The mine water quality monitoring module monitors the mine water treated by the calcification deep treatment module. Qualified mine water, along with pressurized gas generated by the gas generation unit, enters the atomizing nozzle to form a gas-water mixture for dust suppression, reducing clogging of the atomizing nozzle caused by external dust. When the mine water quality monitoring module detects clogging of the atomizing nozzle, the water quality over-limit alarm module will issue an audible and visual alarm and activate the gas-water two-phase flushing module, introducing clean water into the calcification deep treatment module for cleaning. Simultaneously, pressurized gas generated by the gas generation unit is sent into the calcification deep treatment module, where the gas mixes with the clean water to form a gas-water two-phase mixture for deep removal of calcification.

[0025] Step 4: The wastewater after deep removal is discharged through the sewage flushing and discharge unit.

[0026] Compared with the prior art, the present invention brings the following beneficial technical effects:

[0027] This invention proposes an online monitoring and deep treatment method for mine water quality. First, a mine water pretreatment module pretreats the composite particles and organic suspended solids in the mine water to meet the standards for domestic and non-domestic water use and daily mining use. The pretreated mine water is then sent to a calcification deep treatment module for calcification treatment to eliminate calcium ions and other calcification substances that can easily clog micron-level atomizing nozzles, thus providing clean water for the continuous operation of the atomizing nozzles.

[0028] A mine water quality monitoring module, composed of sensors for monitoring mud particles, pH, turbidity, calcium ions, and temperature, monitors key indicators of the mine water used for spraying that cause atomizing nozzle blockage and performs real-time data statistics and transmission. A water quality exceeding limit alarm module monitors the markers causing atomizing nozzle blockage and issues audible and visual alarms. At the same time, it activates a gas-water two-phase flushing module to introduce clean water into the calcification deep treatment module for cleaning. Gas generated by the gas generation unit with a certain pressure is sent into the calcification deep treatment module. The gas mixes with clean water to form a gas-water two-phase mixture, which deeply removes the calcification.

[0029] By utilizing a deep treatment module for calcified substances to remove calcium ions and other calcified substances from mine water, the technical problem of clogging atomizing nozzles during subsequent spray dust suppression is effectively prevented. This significantly extends the service life of the spray dust suppression system, improves the atomization dust suppression effect at coal mine sites, protects the physical and mental health of miners, and achieves economical and precise dust suppression.

[0031] Figure 1 This is a flowchart of the online monitoring and deep treatment method for mine water quality according to the present invention. Detailed Implementation

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0033] It is understood that the connection relationships described in this application refer to direct or indirect connections. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components. For example, A can be directly connected to C, and C can be directly connected to B, thus achieving a connection between A and B through C. It is also understood that the "A connects to B" described in this application can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components.

[0034] In the description of this application, the words "one," "two," etc., are used only to distinguish different objects and do not limit the quantity or order of execution, nor do they imply that they must be different. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0035] The technical solution of this application will be further described in detail below with reference to the accompanying drawings.

[0036] The present invention relates to an online monitoring and deep treatment system for mine water, which includes a mine water pretreatment module, a calcification deep treatment module, a mine water quality monitoring module, a water quality exceeding limit alarm module, a gas delivery module, and a gas-water two-phase flushing module. These multiple modules work together to better remove pollutants in the mine, especially solvent-deposited calcifications, thereby providing clean water for the continuous operation of the atomizing nozzles.

[0037] The mine water pretreatment module includes a raw water centrifugation unit, a particle sedimentation unit, and an activated carbon unit. The raw water centrifugation unit separates heavier impurities from the mine water under centrifugal force and precipitates them in the particle sedimentation unit. Then, the activated carbon unit adsorbs the organic matter.

[0038] Mine water is pumped from the bottom water tank into a sedimentation pretreatment tank via a high-pressure pump. In the sedimentation pretreatment tank, the mine water undergoes pretreatment sequentially through a raw water centrifuge unit, a particle sedimentation unit, and an activated carbon unit. This process removes complex particles such as coal slurry and other organic suspended solids from the mine water, bringing it up to the standard for domestic reclaimed water. The specific structures of the raw water centrifuge unit, particle sedimentation unit, and activated carbon unit can be implemented by those skilled in the art using existing technologies.

[0039] The advanced treatment module for calcified materials mainly includes an ion exchange resin unit, a water softening unit, and a reverse osmosis filtration unit. The ion exchange resin unit dynamically adsorbs high-salt substances from the mine water; the water softening unit initially removes calcium and magnesium ions, which are prone to scaling, from the mine water; and the reverse osmosis filtration unit blocks ions, organic matter, and other impurities, achieving advanced treatment of the mine water. This advanced treatment module eliminates calcium ions and other calcified substances that easily clog micron-level atomizing nozzles, providing clean water for the continuous operation of the atomizing nozzles.

[0040] The mine water quality monitoring module includes a mud particle unit, a pH monitoring unit, a turbidity monitoring unit, a calcium ion monitoring unit, and a temperature monitoring sensor unit. It is primarily used to monitor key indicators of the mine water used for spraying that can cause clogging of the atomizing nozzles, and to perform real-time data statistics and transmission. Mine water that passes the quality monitoring module's test passes through a bubble generator and a water pressure regulator before being sprayed from the atomizing nozzles. As an innovation of this invention, a gas delivery module introduces pressurized gas into the atomizing nozzles, forming a gas-water mixture for atomization and dust suppression, reducing clogging caused by external dust. Therefore, this invention uses a gas-water mixture for atomization and dust suppression at the atomizing nozzles, which differs from existing mine water atomization dust suppression technologies in that the gas-water mixture method does not cause nozzle clogging.

[0041] The gas delivery module includes a gas generation unit and a gas pressurization unit. After the gas generation unit generates gas, the gas pressurization unit pressurizes it, delivering the pressurized gas into the atomizing nozzle. Another function of the gas delivery module is to deliver pressurized gas to the calcification deep treatment module when the atomizing nozzle stops working. The gas, maintained at a certain pressure, mixes with water in the clear water tank, forming a gas-water two-phase mixture that more effectively removes calcification.

[0042] The water quality exceedance alarm module includes an audible and visual alarm and an online alarm unit. When the water quality monitoring detects that the marker that is prone to causing nozzle blockage exceeds the standard, it will issue an audible and visual alarm and simultaneously transmit the alarm signal to the mine water quality monitoring module online.

[0043] The gas-water two-phase flushing module includes a clear water tank, a pipeline flushing pump set, and a sewage flushing discharge unit. The gas generation unit delivers gas at a certain pressure to the calcification deep treatment module, where it forms a gas-water two-phase mixture with the water provided by the pipeline flushing pump set, and performs deep treatment on the calcification. One end of the clear water tank is connected to the calcification deep treatment module, and the other end is connected to the sewage flushing discharge unit.

[0044] The processing method of the present invention will be described in detail below.

[0045] A method for online monitoring and advanced treatment of mine water quality includes the following steps:

[0046] Step 1: Mine water is pumped from the bottom water tank to the sedimentation pretreatment water tank by a high-pressure water pump. It then passes through the raw water centrifugal unit, the particle sedimentation unit, and the activated carbon unit in sequence to filter out the coal mud rock composite particles and organic suspended solids in the mine water.

[0047] Step 2: After pretreatment, the mine water enters the calcification deep treatment module after passing through the spray pressurization pump and one-way valve. It then passes through the ion exchange resin unit, softening water unit, and reverse osmosis filtration unit to perform preliminary treatment of the calcification, providing clean mine water for the atomizing nozzles.

[0048] Step 3: The mine water quality monitoring module is located behind the calcification deep treatment module. A water pressure regulator and atomizing nozzle are connected to the rear of the monitoring module. The monitoring module monitors the mine water treated by the calcification deep treatment module. Qualified mine water, along with pressurized gas generated by the gas generation unit, enters the atomizing nozzle to form a gas-water mixture for dust suppression, reducing clogging caused by external dust. When the monitoring module detects clogging of the atomizing nozzle, the water quality over-limit alarm module will issue an audible and visual alarm and activate the gas-water two-phase flushing module, introducing clean water into the calcification deep treatment module for cleaning. Simultaneously, pressurized gas generated by the gas generation unit is sent into the calcification deep treatment module, where the gas mixes with the clean water to form a gas-water two-phase mixture for deep removal of calcification.

[0049] Step 4: The wastewater after deep removal is discharged through the sewage flushing and discharge unit to ensure the cleanliness of the deep treatment module for calcified substances.

[0050] Any parts not mentioned in this invention can be achieved by referring to existing technologies.

[0051] It should be noted that any equivalent or obvious modifications made by those skilled in the art under the guidance of this specification should be within the scope of protection of this invention.

[0052] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application.
