Aplication and process of oxygen compressor in mining

Oxygen-making air compressors have important applications in mining, especially in ore refining, smelting and mine ventilation. Improve the efficiency and safety of mining processes by preparing high-purity oxygen. The following are its main applications and working processes:

I. Specific applications of oxygen compressors in mining

1. Metal smelting and purification

• Oxygen top blowing steelmaking: by spraying high-purity oxygen, the temperature in the blast furnace is increased to accelerate the oxidation of impurities and metal separation.

• Copper, nickel, lead and zinc smelting: Oxygen-rich environment can reduce fuel consumption and improve smelting speed and purity.

Two. Mine ventilation and safety protection

• In underground mines, oxygen systems are used to provide oxygen support for underground workers to ensure safety in hypoxia or high temperature environments.

• In emergency rescue, portable oxygen-making equipment provides oxygen to trapped people.

3. Gold mine cyanidation gold lifting process

• In the process of cyanification of gold mine, the efficiency of cyanidation reaction is improved through an oxygen-rich environment, the dissolution rate of gold is accelerated, and the consumption of chemicals is reduced.

Four. Gasification and synthetic gas production

• During the gasification process, injecting oxygen into the reactor helps to improve the efficiency of coal conversion and produce more synthetic gas and chemical raw materials.

5. Exhaust gas treatment and environmental protection

• In the exhaust gas treatment system of smelting plants, oxygen-enriched combustion can reduce pollutant emissions and improve the efficiency of exhaust gas purification.

II. The working process of oxygen-making air compressor

1. Inhale

• The oxygen compressor inhales air from the outside and filters the dust and impurities in the air to ensure that clean gas enters the system.

Two. Compress

• Through multi-stage compression, the air is pressurized to the required pressure to improve the efficiency of oxygen separation.

3. Cooling and drying

• The high-temperature air produced during the compression process is cooled by the cooler and the moisture is removed through the drying equipment to avoid freezing or blockage.

Four. Oxygen separation

• The compressed air is sent to a separation device, such as pressure change adsorption (PSA) or low-temperature distillation system, and oxygen and nitrogen are separated by physical or chemical methods.

5. Storage and transportation

• The separated oxygen is stored in storage tanks and transported to mines, smelting workshops or other oxygen-using points by pipelines or tankers.

6. Residant gas treatment

• The isolated nitrogen or other gases can be used for other purposes, such as inert gas protection, pipeline blowing or cooling.

III. Advantages of using oxygen compressors

• Improve production efficiency: The oxygen-rich environment can accelerate the smelting and gold-up processes and reduce downtime.

• Reduce costs: reduce the use of fuels and chemicals and improve energy consumption efficiency.

• Improve the working environment: improve the air quality of the mine through oxygen-enriched ventilation and improve the safety of workers.

• Environmental protection and energy saving: reduce exhaust emissions and meet environmental protection requirements.

Oxygen-making air compressors not only improve process efficiency in mining, but also improve the health and safety of workers. It is a key equipment in modern mining.
