Mining Industry
The mining industry encompasses a range of activities, including exploration, planning, and the extraction of raw minerals through open pit or underground mining techniques. It also includes processing and beneficiation. Mineral processing refers to the process of crushing, grinding, smelting, or refining minerals into final products for distribution.
The mining industry has an impact on fresh water resources through water pollution. This is due to the large amounts of water used in ore processing, mine wastewater discharges, and leaks from tailings and waste rock impoundments. It is inherent to the mining process that water resources are consumed, diverted and severely polluted.
TETRADOM quantum products facilitate the reuse of water resources on multiple occasions and contribute to a reduction in the discharge of industrial wastewater.
CASE 1.
The Coal Mining Company
(Shanxi,China)
The main issues that require attention are as follows:
The water hardness of the production water in the gas drainage station is relatively high, which results in scaling of the pipelines and equipment. This negatively affects the safe operation of the vacuum pump, pressure pump and ancillary facilities of the gas drainage station. The heat exchanger tubes frequently become severely scaled and clogged, making cleaning a challenging process.
The blocked tube holes must be drilled through with a drill bit, soaked in chemicals, and then rinsed repeatedly using mechanical methods combined with high-pressure water guns. This process allows the blockage to be removed gradually. The cleaning process is lengthy and requires significant manual effort.
Installation:
The following locations are available for use:
The total installation comprises seven quantum rings and 32 immersed quantum bars.
1.Quantum Rings:
Four vacuum pumps and three pressure pumps are required. Please install one quantum ring at each of the seven pump inlets.
2. Quantum Bars:
A total of 16 quantum bars are suspended in the circulating water pool, with a further 8 installed in the water tank and a further 8 in the cooling tower.
Effect of Use：
Following approximately one year of operation, the cooling circulation system and water injection circulation system of the dilute oil station have demonstrated favourable outcomes. The circulating water system is capable of functioning normally in the presence of high levels of hardness in the water. A comparison of the scaling conditions before and after the installation of the quantum ring in the cooler of the dilute oil station, along with an evaluation of the performance of the water-injection motor, demonstrates that the quantum ring has a pronounced effect on scaling and anti-scaling. Its performance is highly commendable, as it not only reduces energy consumption and drainage but also safeguards the environment and lightens the workload of manual cleaning, thereby extending the service life of the equipment.
Before
After
Summarize
TETRADOM quantum ring has the effect of increasing the concentration ratio of circulating water, thereby enabling the equipment to operate in a normal manner in environments characterised by high water hardness. The direct consequence of descaling is an enhancement in the efficiency of heat exchange, which consequently results in the conservation of energy. The reduction of emissions, the conservation of water resources and the protection of the environment are all benefits that can be achieved through this process.
CASE 2.
The Coal Mining Company
(Shanxi，China)
The following issues have been identified as requiring attention:
The water used in the circulating system is softened. The gas produced during the manufacturing process contains a significant amount of coal and dust, which has resulted in serious and hard pipeline deposits. These deposits have led to pipeline blockages, reduced efficiency of the circulating water pump, and reduced heat exchange efficiency.
The pumping station requires cleaning on a monthly basis, with the pumps undergoing inspection. The equipment must be returned to the factory for maintenance and descaling once a year. The water sample displays a black and grey colouration, with water loss within the system resulting in the presence of carbonates, sulfates, and silicon within the circulating water. The acid salt plasma concentration is notably elevated and in a supersaturated state.
Effect of Use：
Following the installation of the TETERADOM quantum equipment, laboratory analysis was conducted to monitor changes in turbidity, total hardness, calcium ions, iron ions and other data. The changes in concentration multiples demonstrated that the scale and rust that had formed on the pipe wall began to peel off the pipe after the equipment was installed. This process involved the wall dissolving into the circulating water. The build-up that was causing the clogging has been eliminated, and the system is now operating normally.
The efficiency of the gas drainage pump has been significantly enhanced, leading to a notable reduction in energy consumption and an accelerated improvement in operational efficiency. The need for manual maintenance is eliminated, reducing production shutdown losses caused by cleaning and damage to equipment caused by frequent disassembly, and extending the life of the system.
Summarize
TETRADOM quantum products are highly effective at removing scale that has been deposited over an extended period of time. The increase in Fe and Ca ions is a result of scale dissolution in water. The water hardness has increased, yet the system has not formed new scale and is operating normally. This indicates that TETRADOM quantum products have the effect of changing the concentration ratio of circulating water.
