Reasons and solutions for compressed air purification

Deep purification of compressed air is an indispensable part of industrial production, mainly because compressed air will inevitably carry solid particles, moisture, oil and other pollutants during the generation and transmission process. If these pollutants are used directly without treatment, they will have a serious impact on production equipment, product quality and production safety.

A. Reasons for deep purification of compressed air

1. Reduce equipment loss and prevent equipment failure

Impurities such as solid particles, moisture and oil will cause continuous wear on mechanical parts, shorten the service life of equipment and increase maintenance costs. For example, oil will clog cylinders and pipes, causing system pressure to drop and pneumatic components to fail; moisture may cause corrosion and oxidation, reducing the working efficiency of equipment.

Purified compressed air can reduce the failure rate of equipment and improve the stability and reliability of production lines.

2. Avoid product contamination and improve product quality

In industries such as precision manufacturing, food processing and painting, unpurified compressed air may directly contaminate products and affect product quality and safety. For example, in food processing and pharmaceutical manufacturing, impurities in compressed air may cause product contamination or deterioration, damaging corporate image and market reputation. High-quality, pollution-free compressed air helps produce high-quality products and enhance the market competitiveness of enterprises.

3. Ensure a healthy working environment and prevent occupational diseases

The microbial communities carried in compressed air, including but not limited to bacteria, viruses and fungi, are very likely to induce respiratory infections, such as colds and pneumonia, once they are inhaled by the human body without sufficient filtration, which seriously endangers respiratory diseases. Long-term work in such an environment is more likely to cause occupational diseases, which has a profound impact on the long-term health of workers.

2. Efficient solutions

Hongrijia YUKA has been deeply involved in the field of compressed air purification for more than 20 years. With its professional technical strength and rich industry experience, it provides customers with personalized and efficient compressed air solutions.

1. Multi-stage filtration system: Hongrijia YUKA high-precision pipeline filter can effectively remove dust particles, water mist and oil mist with a diameter ranging from 5μm to 0.01μm,

The filtration efficiency is 99.999%, and the air quality after filtration meets ISO8573 Class1.1.1

According to different user needs, seven levels of filtration accuracy are provided to ensure that each level of filtration can be accurately matched to achieve the best purification effect.

PF grade is used as primary filtration, which can remove particles with a diameter greater than 5μm

AO grade can remove dust particles, water mist and oil mist greater than 1μm. The residual content of oil mist does not exceed 0.6mg/m³ (21℃)

AA grade is high-efficiency oil removal filtration, which can remove dust particles, water mist and oil mist greater than 0.01μm. The residual content of oil mist does not exceed 0.1mg/m³ (21℃)

AX grade is ultra-high-efficiency filtration, which can remove dust particles, water mist and oil mist greater than 0.01μm. The residual oil mist content does not exceed 0.01mg/m³ (21℃)

ACS grade removes oil vapor and odor, and the maximum residual oil vapor does not exceed 0.003mg/m³ (21℃), 0.003ppm (w)

AR grade is installed at the rear end of the adsorption dryer to remove dust particles larger than 1μm

2. Water vapor and water mist can be removed by high-efficiency water removal devices: cold dryers and adsorption dryers

The cold dryers produced by Hongrijia YUKA have achieved significant improvements in heat exchange efficiency and significant reductions in energy consumption with their innovatively designed three-in-one heat exchangers. It can more effectively discharge the liquid water generated by the condensation process, ensuring the stable operation of the system and the purity of the air quality.

Hongrijia YUKA cold dryers use a series of environmentally friendly refrigerants, including R134a, R407c and R410a, which have won wide recognition in the market for their good environmental friendliness and high efficiency. By adopting these advanced refrigerants, the cold dryer not only meets the gas demand of the vast majority of users (more than 85%), but also actively responds to the global call for energy conservation and emission reduction, and contributes to the construction of a green and sustainable production environment.

Hongrijia YUKA's adsorption dryer can deeply remove moisture from compressed air, with a pressure dew point below -20℃ and a drying and filtering moisture efficiency of more than 99.9%. It is suitable for occasions with extremely high requirements for dryness.

The adsorption dryer can deeply remove moisture from compressed air, easily meeting or even exceeding the user's strict requirements for lower dew points. This means that in industries such as electronic manufacturing, food processing, and pharmaceutical production that have extremely high standards for air dryness, the adsorption dryer can become an indispensable partner to ensure the purity and stability of the production environment, thereby improving product quality and ensuring production safety.

Its uniqueness lies in completely abandoning the design of traditional heaters, achieving true zero power consumption and zero carbon emissions, and setting a new benchmark for global environmental protection.

The products produced by Hongrijia YUKA not only ensure that users get the ultimate clean air, but also silently contribute to the sustainable development of the earth.

3. Removal of liquid water: high-efficiency cyclone gas-water separator

Hongrijia YUKA high-efficiency cyclone gas-water separator performs well in removing liquid water from compressed air, and can remove more than 99% of liquid water. This high efficiency ensures that the compressed air entering the subsequent equipment has a very low water content, which has a positive impact on equipment such as dryers and post-treatment filters in many aspects, and significantly improves the performance of these equipment.

4. Condensate discharge: zero air loss float drainer

When dealing with condensate generated during air drying, an efficient and reliable method is needed to ensure that these mixtures containing water, air oil, dirt and rust will not damage the system or cause other problems. As a solution for automatically filtering out condensate, the YUKA float drainer shows its unique advantages.

Due to the constant changes in atmospheric conditions, production loads and air compressor conditions, traditional solenoid valves or manual drain valves are sometimes difficult to adapt to these changes, and sometimes they cause huge energy waste and large amounts of filter leakage due to improper adjustment. The float-type drain can better adapt to these changes and ensure that condensate can be effectively discharged under various working conditions.

Conclusion: During the cooperation process, we are well aware that the specific needs of each customer are unique, so we always put in-depth understanding and accurate grasp of the actual needs of customers first. In view of key factors such as the customer's production environment, equipment type, compressed air consumption, and dryness requirements, we have taken a series of professional analysis and evaluation measures to tailor an air purification solution that best suits the needs of customers.
