Product Description
QVO Vacuum pressure swing adsorption (VPSA) oxygen generator

This kind of oxygen genrator is equipped with blower, vacuum pump, switching valve, the adsorber and oxygen tank.
Air through pressurization then filling into roots blower filled with oxygen molecular sieve adsorber,moisture, carbon dioxide, nitrogen adsorption to produce oxygen.
When adsorption to a certain extent,vacuum pump could make great use of air, vacuum adsorption of moisture, carbon dioxide, nitrogen, and small amounts of other gases were pulled out side by side to the atmosphere, adsorbent regeneration.
The above process steps through PLC and switching valve system to realize automatic control.

Application field and compared with the method of cryogenic
The effect of open hearth oxygen is combustion.Its purpose is to strengthen smelting process, shortening time of smelting and improving open hearth furnace steel production.Practice has proved that open hearth oxygen can make double amount of steel-production, fuel consumption can reduce 33%-50%.
Electric furnace with oxygen can ferment burden of melting and oxidation of impurities which means that the electric furnace oxygen could improve production capacity and improve the quality of special. Smelting electric furnace oxygen consumption of per ton steel differs from the steel grade, for example, oxygen consumption for smelting carbon structural steel per ton is 20-25m3, but oxygen consumption of high alloy steel is 25-30m3. The required oxygen concentration for 90%-94% oxygen enrichment.
Oxygen-enriched air blast furnace can significantly reduce coking, increase production. according to the statistics, increasing 1% oxygen concentration, and its iron production can improve 4%-6%, coking reduce 5%-6%.
In the process of smelting non-ferrous metal, sulfur can be fully burnt, smelting temperature, improve the smelting speed. Take copper for example, copper smelting with enriched air can be energy-saving 50%, under the same burnup, the production of copper can be doubled.

Project/CategoryCryogenic air separation oxygen generatorQVO Vacuum pressure swing adsorption (Vpsa) oxygen generator
Separation principleMake the air liquefacted, according to different oxygen and nitrogen boiling point to achieve separationPressure adsorption and vacuum desorption, separating the oxygen and nitrogen of different adsorption capacity
Process characteristicsProcess complex which need compression, cooling, pretreatment, expansion, liquefaction, shunt, etc., the operating temperature is below -180ºC
The technological process is simple, the operation temperature is normal temperature
Device characteristicsMore moving parts, more complicated structure, more equipment control element
Few movement part, simple equipment, less control element
Operating characteristicsComplex operation, cannot use immediately Easy operation.Operation control and monitor all realized by PLC;Starting and stopping time is short, less than 5 minutes;No need for regular overhaul and maintenance;Operator could work after a short time training
Using rangeNeed a variety of oxygen, nitrogen and argon gas; Oxygen purity is more than 95%Extracting a single gas, purity between 90%-95%
Maintenance characteristicsBecause of the high precision and requirement, centrifugal air compressor, condensing steam engine and expander must equipped with trained maintenance personnelBlower, vacuum pump, all belong to normal maintenance can be performed by ordinary maintenance personnel
Installation characteristicsComplex unit installed, covers big area, long cycle, high cost
Small unit shape, cover small area, conventional installation, short installation period, low cost
Automatic program safety Easily broken and affect the normal operation of equipmentAfter startup can run fully automatic;All safety factors, without the possibility of an explosion
Purity adjustmentPurity adjustment is not convenient, cost is high
Simple purity adjustment and low cost to generate oxygen
Oxygen generating costenergy consumption:>1.25kwh/m3Energy consumption:<0.35kwh/m3
Total investmentHigh costsLow cost
