工藝流程簡介Brief introduction of process flow

環(huán)境空氣經壓縮凈化，除去油、水、塵后，進入由兩個裝填有碳分子篩的吸附塔組成的變壓吸附裝置。壓縮空氣由下至上流經吸附塔，其間氧分子在碳分子篩表面吸附，氮氣由吸附塔上端流出，進入氮氣緩沖罐，經過一段時間后，吸附塔中碳分子篩被吸附的氧飽和，需進行再生。再生是通過停止吸附步驟，降低吸附塔壓力來實現(xiàn)的。兩個吸附塔交替進行吸附和再生，從而確保氮氣的連續(xù)輸出。

The ambient air is compressed and purified, and after removing oil, water and dust, it enters a pressure swing adsorption device composed of two adsorption towers filled with carbon molecular sieve. The compressed air flows through the adsorption tower from bottom to top, during which oxygen molecules are adsorbed on the surface of the carbon molecular sieve, and nitrogen flows out from the upper end of the adsorption tower into the nitrogen buffer tank. After a period of time, the carbon molecular sieve in the adsorption tower is saturated with adsorbed oxygen and needs to be regenerated. Regeneration is achieved by stopping the adsorption step and reducing the adsorption column pressure. The two towers alternate adsorption and regeneration to ensure a continuous output of nitrogen.

三、技術特點

   1、原料空氣取自自然，只需提供壓縮空氣和電源即可制氮氣。設備能耗低，運行成本費用少。內置空氣凈化、干燥系統(tǒng)，確保壓縮空氣品質，提高分離效果。

   2、氮氣純度調整方便，氮氣純度只受氮氣排氣量的影響，制氮純度在95%－99.9%之間任意調節(jié)。

   3、設備自動化程度高，產氣快，無人值守。啟動、關機只需按一下按鈕，開機10-15分鐘內即可產生氮氣。

   4、設備工藝流程簡單，設備結構外形緊湊，占地面積小，設備裝置適應性強。

   5、暴風雪法裝填分子篩，避免高壓氣流沖擊導致分子篩粉化現(xiàn)象，確保分子篩長時間使用。

   6、分析儀在線檢測，高精度，免維護

Three, technical characteristics

1. Raw air is taken from nature, and nitrogen can be produced only by providing compressed air and power supply. The equipment has low energy consumption and less operating costs. Built-in air purification and drying system, to ensure the quality of compressed air, improve the separation effect.

2, the purity of nitrogen is easy to adjust, nitrogen purity is only affected by nitrogen exhaust volume, nitrogen purity can be adjusted between 95% and 99.99%.

3, high degree of automation, fast gas production, unattended. Start, shut down just press the button, boot within 10-15 minutes can produce nitrogen.

4, the equipment process is simple, the equipment structure is compact, the area is small, the equipment is strong adaptability.

5, snowstorm method loading molecular sieve, avoid high pressure air impact caused by molecular sieve powder phenomenon, to ensure the long-term use of molecular sieve.

6, analyzer online detection, high precision, maintenance free
