Air compressors have been widely used in all aspects of industry, but currently most compressors must use lubricating oil when working. As a result, the compressed air inevitably contains oil impurities. Generally, extensive enterprises only install a physical oil removal component. Regardless, this type of component can only target oil droplets and oil mist in gases, and the air also contains molecular oil.
There are currently three methods used to highly purify the air:
1. Cooling and filtering
The main principle of this method is to cool down. The simple principle of this method is to liquefy the oil molecules and turn them into oil mist, which is then filtered again. The cost is low. If the filter element used for filtration has a higher precision, most of the oil mist can be removed, but It is difficult to completely remove the oil, the gas can only meet the general air quality requirements, and the filter element precision is required to be high.
2. Activated carbon adsorption
Activated carbon can effectively remove impurities in the air, and the effect is excellent. The purified air can meet higher gas usage requirements, but the cost of activated carbon is high. After a long time of use, the purification effect will decrease and must be replaced. The replacement cycle is affected by the amount of oil, and It is unstable. Once the activated carbon is saturated, the consequences will be serious. It cannot continuously remove oil. To replace the activated carbon, you must also make concessions in the design.
3. Catalytic oxidation
The principle of this method can be simply understood as the oxidation reaction of oil and oxygen in the gas, “burning” the oil into carbon dioxide and water.
This method has high technical requirements, and its core is the catalyst for the reaction. Since combustion cannot actually occur, a catalyst must be used to accelerate the reaction process. The catalyst must have a large contact area with the gas, and the catalytic effect must also be powerful.
In order to enhance the catalytic effect, the reaction must be carried out under high temperature and high pressure, and heating equipment must be installed. The energy consumption requirement is greatly increased, and because the oil molecules in the gas are far less than oxygen molecules, in order to ensure the effect, the reaction time also has certain requirements, so a reaction chamber is necessary. If the equipment detection and process technology are not high, it will be difficult to achieve. requirements, the initial investment cost of the equipment is high, and the quality of the equipment varies, and there are risks. However, excellent equipment can reduce the oil content of the gas to an extremely low level and meet the oil-free requirements, and the catalyst does not participate in the reaction itself, so the service life is long, and The time is determined, and the later investment is low except for energy consumption.
In recent years, with the continuous development of industrial production, air compressors have played an increasingly important role in the production process. However, when some companies use air compressors, they find that the gas produced by the air compressor is too greasy, which not only affects production efficiency, but may also cause environmental pollution. In order to solve this problem, experts have proposed three major measures to help companies purify the air and improve production efficiency.
First of all, experts recommend that companies install air purification equipment when using air compressors. By installing a filter and oil-water separator at the outlet of the air compressor, the grease and moisture in the gas can be effectively removed, ensuring the purity of the air, reducing damage to production equipment, and improving production efficiency.
Secondly, regular maintenance of the air compressor is also the key to purifying the air. Regularly replacing the filter element and filter screen, cleaning the oil-water separator, and checking whether the pipe connections are loose can effectively reduce the grease and impurities in the gas and ensure the cleanliness of the air.
Finally, businesses can consider using high-efficiency synthetic air compressor oils. Traditional mineral oil is prone to precipitation and dirt during use, causing the gas to become greasy. Synthetic air compressor oil has excellent cleaning performance and stability, which can effectively reduce the grease content in the gas and ensure the purity of the air.
To sum up, in order to solve the problem of air compressor gas being too greasy, companies can take three major measures: installing air purification equipment, regular maintenance and using efficient synthetic air compressor oil to effectively purify the air and improve production efficiency. Contribute to environmental protection. It is hoped that all enterprises will pay attention to air purification and jointly create a clean and healthy production environment.
