How it works
The four-tower containerized nitrogen generator is a mobile nitrogen generator that integrates an air compressor, purification system, and nitrogen production system. This unit utilizes pressure swing adsorption (PSA) technology to separate oxygen and nitrogen in the air based on their differential adsorption using carbon molecular sieves, producing high-purity nitrogen. The four-tower containerized units in the Shenger nitrogen generator series feature a compact, modular design, making them ideal for industrial sites with strict space requirements and the need for rapid deployment of nitrogen sources.
四塔一體集裝箱制氮機是一種將空壓機、淨化系統和制氮系統集成於一體的移動式氮氣發生設備。此類設備採用**變壓吸附（PSA）**技術，通過碳分子篩對空氣中氧氣和氮氣的吸附差異進行分離，從而產生高純度氮氣。盛爾制氮機系列的四塔集裝箱機組，結構緊湊小巧、模塊化設計，適合對空間要求嚴格、需要快速部署氮氣氣源的工業現場。（圖：四塔一體集裝箱制氮機外觀示意圖）
The membrane separation nitrogen maker and the PSA pressure pressure adsorption nitrogen maker have much the same flow, the air is compressed, purified, the nitrogen is separated, and finally in the nitrogen buffer tank. The difference lies in the different ways of separating and removing nitrogen, membrane separation mainly uses central control fiber membranes for nitrogen and oxygen separation. Nitrogen purity is not as high compared to PSA nitrogen generators, generally below 99.9%. Membrane separation nitrogen generators also have their own advantages:
- 操作簡單，運行可靠，自動化程度高，冇運動部件，無需循環切換，滿足長期連續運行要求；
開/停車方便迅速，開機10分鐘左右即可生產合格氮氣：運行能耗低，氮氣純度連續可調；
氣體分離過程冇噪音，冇污染，唔產生有害廢物，產氮潔淨度高；
可通過增加膜組件來擴大系統嘅產氮能力，滿足客戶對唔同氮氣產量嘅需要；
具有膜組進氣品質檢測同保護裝置，確保合格氣體進入膜組件，提高咗膜嘅使用壽命；
整機結構緊湊，安裝方便，佔地面積小適用範圍廣，能抗許多化學污染。
System structure and working principle
- A four-tower containerized nitrogen generator typically consists of a container housing, an air compressor unit, a freeze dryer, an air filter, a gas storage tank, and an adsorption tower assembly. The containerized design facilitates transportation and installation; simply connect the power supply and compressed air lines to the system. Its core component is a PSA unit equipped with four adsorption towers (two dual-tower adsorption systems): one adsorption tower produces nitrogen from the separated gas stream, while the other simultaneously regenerates the adsorption bed, achieving continuous nitrogen production.
- During operation, pre-treated, dry, clean compressed air enters the adsorption tower. Oxygen molecules, due to their rapid diffusion rate, are adsorbed by the carbon molecular sieve, while nitrogen flows out of the tower and is sent to the crude nitrogen tank. After a period of adsorption, the saturated adsorption tower switches to desorption and regeneration mode, restoring the molecular sieve's adsorption capacity through decompression or backflushing. This alternating cycle ensures continuous and stable nitrogen output. This four-tower configuration further improves nitrogen production capacity per unit time and system redundancy, maintaining efficient and long-term operation.
Main technical parameters
The four-tower integrated container nitrogen generator has the following typical technical parameters (specific data may vary depending on the actual model):
產氮量：依據空壓機功率及吸附塔容量不同，可提供數十至數千標準立方米/小時的氮氣產量，滿足中小型工業用氣需求。
Nitrogen purity rangePurity: Generally adjustable between 95% and 99.999%, target purity can be set based on downstream process requirements. Common industrial purities such as 99% and 99.5% can be stably achieved to meet diverse process requirements.
出口壓力：氮氣工作壓力可調，通常在0.1~1.0MPa範圍內自由配置，以符合不同壓力等級需求的用氣設備。
露點溫度：集裝箱內配置冷凍式乾燥機，氮氣露點可達**-40℃至-60℃**，提供乾燥潔淨的氮氣品質，確保對用氣環境無水分影響。
電力消耗：制氮機組整體功率隨產氮量與純度需求變化。通常每產1標準立方米氮氣需消耗約0.3~0.6度電（kW·h），高效的能量利用設計可讓整機實現穩定低耗運行。
設備尺寸與材質：集裝箱採用符合食品衛生級標準的防護塗層或不銹鋼材質，耐腐蝕性強。標準尺寸根據產能不同而定，常見尺寸有20英尺和40英尺集裝箱大小，便於海陸空運輸與現場佈署。
Energy consumption and operating efficiency
- 在能源效率方面，盛爾四塔集裝箱制氮機採用先進的節能技術：配備變頻空壓機可根據氮氣需求自動調節輸出氣量，避免空壓機長時間滿負荷運行造成的能耗浪費；同時採用PLC自動控制系統，可實現定時啟停及負荷控制，進一步降低非必要運行時的電能消耗。此外，再生流程中部分高壓氮氣回吹吸附塔用於解吸，可有效回收部分能量。實際使用中，單位氮氣電耗通常保持在0.4度/kW·h以下，顯著優於傳統老舊裝置。高效率的能耗設計意味著運行成本更低、投資回收期更短，符合能源節約和降低碳排放的現代工業要求。
Applicable environment and reliability
- 集裝箱式制氮機的外殼結構堅固，對各種惡劣環境具有出色的適應性。其密閉機箱採用防塵防腐設計，可有效隔離外界灰塵、濕氣和腐蝕性氣體。經驗證證明，此類設備在高溫、低溫、高海拔、潮濕等條件下均能保持穩定運行，無須特別的空調或環控設施。配備強制通風冷卻系統和隔振底座，能防止機組因溫度升高或振動引發的性能波動，確保長時間持續運作。
- In addition, the PLC control system incorporates multiple safety features, including overload protection, high-pressure alarms, and self-diagnosis fault shutdowns. These features automatically halt the nitrogen production process and issue warnings if an anomaly occurs, mitigating operational risks. Routine maintenance is also convenient: the container's modular components are neatly arranged, and key components such as the air filter, freeze dryer, and molecular sieve bed are easily replaced and maintained, ensuring equipment reliability and longevity. These features ensure the containerized nitrogen generator can reliably supply gas under a variety of field conditions.
