When discussing industrial manufacturing or other applications requiring compressed air, air quality is an often overlooked but crucial element. We often focus on ensuring our compressed air systems provide enough pressure to drive equipment. But we rarely consider the humidity and purity of the air. This is where compressed air dryers become essential.
This article explores why compressed air dryers are indispensable equipment in many situations. We’ll look at when you might need a compressed air dryer. Whether you are an industrial manufacturer or use compressed air daily, this article will help you better understand why you should consider investing in a quality compressed air dryer. Let’s explore how this seemingly small but important device can have a profound impact on a variety of applications.
Where Does The Water in Compressed Air Come From?
الرطوبة في الهواء المضغوط تأتي في المقام الأول من الغلاف الجوي. وهذا متأصل في الهواء الطبيعي. بغض النظر عن الموسم, the atmosphere has a certain relative humidity. فضلاً عن ذلك, بعد الضغط أو التبريد, the water vapor in the air will become liquid. وهذا يؤثر على جودة الهواء المضغوط.
In industrial air compressor applications, many users are very sensitive to moisture. Since we can’t eliminate the water before the air compressor, it must remove moisture in the compressed air treatment system.
قبل دخول ضاغط الهواء, الرطوبة الموجودة في الهواء هي في الأساس بخار الماء. وهي غير مشبعة. كما هو موضح في الورقة 1, الرطوبة النسبية للهواء هي 69%, ودرجة الحرارة 20 درجة مئوية. بعد الضغط (7 حاجِز), the water vapor in the compressed air becomes saturated because of the cooling of the rear cooler of the air compressor. And 42% of liquid water will be precipitated. A gas-water separator and storage tank can remove this liquid water. The remaining 58% of water is in the compressed air as water vapor.
If there is no air compressor dryer, the direct use of compressed air will be bad for production. لذلك, refrigerated and desiccant air dryers have become the preferred air treatment equipment.
There are three general requirements for the water content of compressed air.
① The air compressor discharges compressed air. If there is a cooler + air receiver, then it can lower the temperature by 3 ل 10 درجه مئوية. This can meet customers with low-quality air, such as drilling rigs, مدافع الهواء, إلخ.
② But most industrial enterprises generally have such requirement :10درجه مئوية>نقطة الندى الضغط>0درجه مئوية. This requires using an air compressor refrigerated dryer to remove the water vapor.
③ If the need for dew point ≤ 0 درجه مئوية, choosing a desiccant air compressor air dryer is necessary. The common dew point requirements for adsorption compressed air dryers are -20℃, 40درجه مئوية, and 70℃.
What Are The Specific Problems That Arise?
يقوم ضاغط الهواء بتفريغ الهواء المضغوط, ولكنها ليست نظيفة. There are many contaminants, مثل الرطوبة, جزيئات الغبار, زيت, إلخ. They will enter the production process if they are not purified and dry. علاوة على ذلك, العديد من ضواغط الهواء اللولبية هي من النوع الزيتي. This leads to many problems.
Production Capacity Decline
If there is no air dryer compressed air, moisture, and oil will clog and rust pneumatic equipment and tools. وهذا يسبب بطء التشغيل. بجانب, انسداد الخطوط والأجزاء سيؤدي إلى انخفاض الضغط. وسوف تفقد الأدوات كفاءتها. In a long time, سوف تتعطل المعدات. في الحالات الشديدة, هذا يمكن أن يؤدي إلى توقف الإنتاج.
Increase Product Defect Rate
يؤدي المحتوى المائي العالي في الهواء المضغوط إلى زيادة معدل فشل المنتج. على سبيل المثال, spray painting and electronic product processing. في ماكينات القطع بالليزر أو البلازما, سوف تلوث الرطوبة العدسات الموجودة على رؤوس القطع لدينا. لذا, it will directly affect the cutting efficiency.
فضلاً عن ذلك, various influence exists in the food industry. غالبًا ما يلعب الهواء المضغوط دورًا في تغليف المواد الغذائية ونقلها. أيضًا, غالبًا ما يتلامس الهواء المضغوط مع المنتج.
إذا لم يكن هناك مجفف هواء ضاغط الهواء, then much moisture or oil can damage our food. وخاصة في صناعة المواد الغذائية الجافة, هناك متطلبات أكثر صرامة لرطوبة الهواء. تتضمن معايير ISO فئات مختلفة لجودة الهواء المضغوط في صناعة الأغذية. Different levels have different contents of solids, ماء, والنفط.
Air Aerodynamic Loss
الماء الموجود في الهواء المضغوط سوف يؤدي إلى تآكل الأنابيب. وهذا يؤدي إلى انسداد الأنابيب. علاوة على ذلك, mixing water, زيت, and dust can exacerbate blockages. بجانب, في المناطق الباردة, يمكن أن يؤدي تجميد الرطوبة إلى تجميد الأنابيب. ثم ينخفض الضغط ويصبح فرق الضغط كبيرًا. مؤخراً, it will affect the safety of production. فضلاً عن ذلك, it will lead to air leakage from the pipeline in serious cases.
لذلك فهو يحتاج إلى مجفف الهواء المضغوط المبرد ومجفف ضاغط الهواء المجفف لإزالة الماء.
Increase Production And Maintenance Costs
سوف تؤدي الرطوبة والزيت إلى إتلاف مكوناتنا الهوائية بشكل مباشر. بجانب, they will also corrode our equipment. ثم يتعين علينا استبدال قطع الغيار بأخرى جديدة. وهذا يزيد من تكلفة الصيانة وتكلفة وقت الإنتاج.
To improve compressed air quality, you must install precision filters to remove oil and water. ثم, install an air compressor air dryer to remove the water deeply. وبذلك تصل نقطة الندى إلى متطلبات التطبيق.
What Can Compressed Air Dryers Bring You
A compressor air dryer is a device used to process compressed air. It improves compressed air quality by removing moisture and other impurities from the air. Below are some of the main functions the air compressor dryer can perform.
Dehumidification
Compressed air often contains significant amounts of moisture, harming many applications. Compressed air dryers remove moisture from the air through technologies such as cooling, adsorption, or membrane separation. This prevents moisture from corroding, icing, or other problems with equipment and processes.
Purify
The air may contain particulate matter, grease, bacteria, وغيرها من الشوائب. These impurities can cause problems in some sensitive applications. Air dryer compressed air can filter these impurities and provide cleaner and purer compressed air.
Improve System Efficiency
Dehumidification and purification of compressed air can improve the efficiency of compressors and pneumatic equipment. Dry air transports energy more efficiently, reduces corrosion on pipes and equipment, and reduces maintenance costs.
Extend Equipment Life
Compressed air dryers can extend the life of compressors, الصمامات, and other critical components by reducing damage to equipment from moisture and impurities, downtime, and repair costs.
Ensure Product Quality
In some manufacturing processes, compressed air is used to carry raw materials or participate directly in the manufacture of products. If the air contains moisture or contaminants, this may adversely affect product quality. Air dryer compressed air ensures that products are free from contamination and meet quality standards.
When Do You Need A Compressed Air Dryer
There are many situations where you might need an air compressor dryer. It depends on your application and environment. Below are some common situations.
Pneumatic Equipment
If you work with pneumatic tools, control systems, or machinery, dry compressed air is essential to their proper operation. Moisture can cause stuck valves, leaky cylinders, or tool failure.
Precision Manufacturing
In precision manufacturing, مثل الالكترونيات, semiconductor, or optical manufacturing, tiny water droplets or particles in the air can cause damage to products. The air compressor dryer ensures the required air quality during production.
Food And Pharmaceutical Industry
In food and pharmaceutical production, hygiene standards are very strict. Moisture and contaminants can pose a threat to product safety and quality. Dry compressed air helps avoid these problems.
Cooling And Freezing Applications
In cooling and freezing systems, dehumidified compressed air helps prevent freezing and frost and maintains stable system operation.
Painting And Coating
If you use compressed air in automotive painting, woodworking, or other coating applications, moisture, and oils can adversely affect the quality of the coating. A compressed air dryer ensures uniform coating and good quality.
Gas Production
Certain gas production processes require extremely high-purity gases, and dehumidification and purification of compressed air are key steps in producing high-purity gases.
Avoid Pipeline Corrosion
Moisture and contaminants can trigger corrosion in pipes and vessels. This may cause leakage or damage to the equipment. Compressor air dryers protect equipment and infrastructure from such hazards.
Energy Saving
Dehumidified compressed air requires less energy to transport. Drying air, therefore, reduces energy costs and increases system efficiency.
