1.Application and Features
XZNZDJ nitrogen generator is widely used in the food industry, packaging, storage and preservation, wine packaging and preservation, as well as pharmaceutical, electronics, coal mining, petroleum and other industries. The device has the characteristics of low operating cost, simple structure, small footprint, safety and reliability, easy operation, and high recovery rate.
2.Working principle
This equipment adopts the principle of PSA pressure swing adsorption, utilizing the ability of carbon molecular sieves to separate nitrogen from air under pressure changes. Using air as raw material, compressed air is purified through processes such as oil removal, drying, and filtration before being sent to the adsorption component composed of two towers. The compressed air undergoes overpressure adsorption in the tower to produce nitrogen gas, while the other tower undergoes desorption and regeneration. The two towers alternate and continuously obtain cheap nitrogen gas with a purity of 98-99.9%.
3、 Equipment composition
This device consists of two main parts: air source purification and purification. Air source purification consists of the following units:; Freeze drying unit, oil removal unit, adsorption unit, air buffer tank unit. Air purification consists of a pressure swing adsorption unit and a nitrogen buffer unit. This device is mainly used to separate inexpensive nitrogen from the air for use.
4、 Process description
The stable compressed air source provided by the oil-free compressor is removed from most of the water and some of the oil mist in the compressed air by a cold dryer, and then removed from trace amounts of oil and water by an oil remover. It is then deeply dehydrated by an oil-free regeneration dryer and filtered to obtain dry and clean compressed air, which is stored in an air buffer tank. Then, the dried air is passed through a pressure swing absorber, and the oxygen and carbon dioxide in the air are adsorbed by carbon molecular sieves. After purification by the absorber, nitrogen gas is obtained, which is filtered to obtain relatively clean nitrogen gas and enters the nitrogen buffer tank for use. The oxygen controller can detect the oxygen content in nitrogen online. Thus obtaining the purity of nitrogen gas. The nitrogen in the nitrogen buffer tank is output through a pressure reducing valve and flow meter for user use.
This device has a simple process flow, easy operation, compact structure, and small footprint; Atmospheric regeneration, significant energy saving, low nitrogen production cost, system interlocking, safety and reliability. This device is an ideal small-scale nitrogen air separation equipment, widely used in nitrogen filling packaging and storage of beer, beverages, food, fruits, petrochemicals, metallurgy, heat treatment, pharmaceuticals, electronics and other industries.
