Metallurgical Industry

The mining industry includes exploration, planning, extraction of raw minerals through open pit or underground mining techniques, processing and beneficiation. Mineral processing: The process of crushing, grinding, smelting, or refining minerals into final products for distribution.
The mining industry affects fresh water through water pollution through large amounts of water used in ore processing, mine wastewater discharges, and leaks from tailings and waste rock impoundments. Mining by its very nature consumes, diverts and severely pollutes water resources.
TETRADOM quantum products can reuse water resources many times and reduce the discharge of industrial wastewater.

CASE 1.

Coal Mining Company

(China. Shanxi)

Pain Points:

The water hardness of the production water in the gas drainage station is relatively high, and the pipelines and equipment are easily scaled, which affects the safe operation of the vacuum pump, pressure pump and ancillary facilities of the gas drainage station. Severe scaling and clogging of heat exchanger tubes often occur, making cleaning very difficult.
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. can be removed gradually. The cycle of cleaning equipment is long and the labor intensity of workers is high.

Installation:

The usage locations are:

Total install 7 quantum rings and 32 immersed quantum bars.

1) Quantum Rings:

4 vacuum pumps and 3 pressure pumps. Install 1 quantum ring at each of the 7 pump inlets.

2) Quantum Bars:

16 quantum bars are suspended in the circulating water pool, 8 quantum bars are installed in the water tank, and 8 quantum bars are installed in the cooling tower.

Effect of Use:

After nearly one year of operation, the cooling circulation system and water injection circulation system of the dilute oil station have achieved good results. The circulating water system can work normally under high hardness water conditions. By comparing the scaling conditions before and after installing the quantum ring in the cooler of the dilute oil station and the operation of the water-injection motor, it can be seen that the quantum ring’s descaling and anti-scaling effect is extremely obvious and its performance is excellent. It not only reduces energy consumption, reduces drainage and protects the environment, but also reduces the workload of manual cleaning and greatly extends the service life of the equipment.

Before

After

Summarize

TETRADOM quantum ring increases the concentration ratio of circulating water, allowing the equipment to operate normally in high hardness environments. The direct effect of descaling is to increase heat exchange efficiency and save energy. Reduce emissions, save water resources, and protect the environment.

CASE 2.

Coal Mining Company

(China. Shanxi)

Pain Points:

The replenishing water of the circulating water system is softened water. Since the gas generated during the production process contains a large amount of coal and dust, the dust in the pipelines is serious and hard, causing pipeline blockage, reduced efficiency of the circulating water pump, and reduced heat exchange efficiency.
The pumping station needs to be cleaned once a month and the pumps are inspected. The equipment must be returned to the factory for maintenance and descaling once a year. The color of the water sample is black and gray, and the water in the system is lost, causing carbonates, sulfates, and silicon in the circulating water. The acid salt plasma concentration is very high and is in a supersaturated state.

Effect of Use:

After the TETERADOM quantum equipment was installed, laboratory analysis was carried out through the changing characteristics of turbidity, total hardness, calcium ions, iron ions and other data. Combined with the changes in concentration multiples, it was shown that the scale and rust attached to the pipe wall gradually peeled off the pipe after the equipment was installed. wall and dissolve into the circulating water. The clogging build-up is eliminated and the system can operate normally.
The heat exchange efficiency of the gas drainage pump has been greatly improved, energy consumption has been reduced, and work efficiency has been rapidly improved. There is no need for manual maintenance anymore, which reduces production shutdown losses caused by cleaning and damage to equipment caused by frequent disassembly, and extends the life of the system.

Summarize

TETRADOM quantum products are very effective in removing scale that has been deposited for many years. The increase in Fe ions and Ca ions is caused by scale dissolving in water. The hardness of the water is higher than before, but the system does not form new scale and can operate normally, indicating that TETRADOM quantum products do have the effect of changing the concentration ratio of circulating water.
