Why Choose Our Stainless Steel Compressed Air Desiccant Dryer
(1) 304 Stainless Steel Material
ประการแรก, compressed air contains a lot of moisture. Ordinary regenerative dryer systems are prone to rust. ด้วยประการฉะนี้, it will pollute the air. It can also damage downstream air-use equipment.
ประการที่สอง, many industries have requirements for dryer materials. Especially the medical and food industries. Air quality requirements are higher. ดังนั้น, the dryer material must be stainless steel. Compressor desiccant dryers can’t use carbon steel.
นอกจากนี้, other special industries are also the same. ตัวอย่างเช่น, the new energy lithium battery industry. They prohibit using zinc, copper, and nickel elements in drying machines. Because of these materials, dust will fall into the lithium battery. It may cause a polarized reaction. Heat destroys the diaphragm. ในที่สุด, it will cause the battery to explode or burn. ดังนั้น, it must choose a stainless steel regenerative desiccant air dryer.
(2) ประหยัดพลังงานสูง
Suppose there is an oil-free centrifugal air compressor. Its air capacity is 200m3/min. And the power is about 1100KW. ดำเนินการอย่างต่อเนื่อง 365 วันทำงานต่อปี. The electricity fee is CNY1.0/kWh. นอกจากนี้, the water fee is CNY0.2/ton.

เพื่อสรุป, the micro air loss blower regenerative dryer is more energy efficient.
(3) Use High Quality Parts And Materials
The structure of a regenerative desiccant air dryer is simple. It mainly controls the airflow through various valves. ประการแรก, we use high-quality pneumatic valves. It is metal-seated and heat-resistant. And it’s a German brand. ดังนั้น, the failure rate is low. Our compressor desiccant dryer is stable in performance.
ประการที่สอง, we use high-performance adsorbents. นอกจากนี้, our desiccant filling amount is sufficient. It’s 20% more than other dryers. This dryer uses activated alumina and a 4A molecular sieve.
(4) จุดน้ำค้างที่เสถียร
Our dryer dew point fluctuation is small. This is mainly due to the following reasons.
① ประการแรก, the filling capacity of our desiccant beads is very sufficient. So it can maintain a high drying effect.
② ประการที่สอง, มีโครงสร้างกระจายลม. These devices are at the bottom of our regenerative desiccant air dryer. ดังนั้น, the air and the adsorbent are in full contact. And it can fully remove the moisture.
③ Third is the most important. Our regenerative dryer adopts an EBX200-2 control system. This is a multi-core drive control mode. This is more than 30% more energy saving than single-core mode. Because it can adjust the operation efficiency of the dryer.
How does micro air loss blower purge regenerative desiccant air dryer work
This compressor desiccant dryer has an independent blower. So it can suck in the surrounding air. จากนั้นเครื่องทำความร้อนจะทำให้อากาศร้อน. หลังจากนั้น, hot air can heat the desiccant beads. This will desorb moisture. But this is different from zero air loss regenerative dryer. It uses a small amount of regeneration air for cold purging. This ratio is about 2%. ดังนั้น, they can cool down the regeneration tower. It only consumes very little compressed air. The following is the working process of the dryer:
(1) The drying process of regenerative desiccant air dryer
This process is also called adsorption. Saturated compressed air has a lot of moisture. They pass through the desiccant beads in the drying tower. The adsorbents have capillary pores on it. So they can absorb a large amount of water vapor.
(2) Desorption process of compressor desiccant dryer
Desorption involves at least six processes:
Pressure relief→hot purge→cold purge→pressure boost→standby→TSE dew point energy saving control (optional)→process change
① ประการแรก, depressurize the regeneration adsorption tower. Reduce it to atmospheric pressure. Then compressor desiccant dryer start next process.
② ประการที่สอง, start the thermal purge process. Air is drawn in by means of a blower. Then heat it with an electric heater. ในที่สุด, blow the hot air into the adsorbent. So they can remove moisture.
③ Then there is the cold blowing process. The regenerative desiccant air dryer utilizes 2% of the system air. It gradually reduces the temperature of the adsorbent.
④ The previous process ends. The regeneration discharge valve closes. ในเวลาเดียวกัน, the cold blow regeneration valve remains open. เพิ่มและเข้าถึงแรงดันใช้งาน.
⑤ The rest of the process is the same as the zero air loss regenerative dryer.
How to operate regenerative desiccant air dryer rightly
(1) Inspection before starting compressor desiccant dryer
① ประการแรก, check the appearance of regenerative dryer. Observe whether the adsorption air dryer is complete.
② ประการที่สอง, check the electrical schematic diagram. Confirm if the wiring of regeneration dryer is loose.
③ ประการที่สาม, check whether the air pipe of each valve is loose. นอกจาก, oberve whether the setting value of the pressure reducing valve is normal (the setting value should be 0.5~0.6Mpa).
④ Sometimes there are also compressed air filters. Also check that the front and post filters are installed correctly.
(2) Start-up steps of blower heat regenerative dryer
① ประการแรก, slowly close the outlet stop valve. Pressurize the two drying towers to pipe pressure.
② ประการที่สอง, check the compressor desiccant dryer for leaks. ณ ขณะนี้, keep the regeneration exhaust valve closing.
③ ประการที่สาม, กดปุ่มเริ่มต้น. Start the regenerative desiccant air dryer.
④ The regeneration exhaust valve opens automatically. One of the two drying towers begins to depressurize.
⑤ Let the regenerative dryer run for one or two working cycles. Then open the outlet valve again.
⑥ If there is too much dust in the air, please stop the desiccant dryer. And replace the desiccant beads.
(3) Observe the operation of the adsorption dryer
① The pressure of the drying tower should be the same as the pipeline pressure. The pressure gauge on the tower has a display.
② The pressure of the regeneration tower should be 0.
(4) Maintenance of blower heat regenerative desiccant air dryer
① During the first month, clean the filter element. And it should be replaced regularly in the future. อีกด้วย, clean the dryer muffler. If the regeneration tower pressure is greater than 0.035Mpa, replace the muffler.
② Every three months, close the pressure reducing valve. Then check the pneumatic valve for leakage.
③ It needs no lubrication in the regenerative desiccant air dryer.
④ Check the automatic drain valve on the filters every day.
⑤ Check whether the actions of regenerative dryer are normal.
⑥ Regularly observe the operating conditions of compressor desiccant dryer.
⑦ Check the filter pressure drop. If exceeds 0.07Mpa, replace the filter element.
⑧ Every three months, close the inlet/outlet valve. Completely depressurize the regenerative desiccant air dryer system. Open the desiccant filling port. Sampling to check desiccant. If the adsorbent is with oil and crushed, replace them.
