KDON- Type liquid oxygen generating machine is one of most cost-effective liquid ASU. This kind of liquid machine produces high purity liquid oxygen and liquid nitrogen. The application of advanced technical process brings a high productivity of machine.
The detail technical parameter are as following:
| Performance Specification | |||||
| Mode | Working condition | Product | Flow rate | Purity | Cooling method |
| KDON- | I | Liquid oxygen | ~Nm3/h (Customized) | O2 ≥99.6% | Air cooling |
| II | Liquid nitrogen | ~Nm3/h (Customized) | N2 ≥99.999% | ||
| III | Liquid oxygen + liquid nitrogen | ~Nm3/h (Customized) | |||
| Start-up time | 6~8h | ||||
| Plant shutdown for scheduled maintenance | ≥ 24 months | ||||
| Air compressor The inlet air will be compressed into the pressure as per process required. It is sprayed-oil screw compressor, box-body construction, it have low noise, whole machine gather gas, lubricate, water, electric, cooling and instrument to one, realize machine and electric become one body. |
Pre-cooling unit The outlet temperature of compressed air is around 40ºC which is too high for the down-stream molecular sieves high efficiency operation, in order to increase the performance of the molecular sieves, a pre-cooling unit is required. |
Purifier Remaining contaminants in the process air such as moisture, carbon dioxide, acetylene (and etc.) shall be removed before enters into the main heat exchanger, a molecular sieves system is adopted. |
| Turbine expander Turbine expander also referred to as a turbo-expander, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work. It's the one of core part of the whole plant. |
Fractionating column It adopt fin type heat exchange, made in aluminum, heighten heat exchange affection, depress the operating pressure, reduce the power consumption furthest, saving cost. |
Liquid pump Liquid oxygen pump is a kind of cryogenic liquid pump, by which the pressure of oxygen can be increased to achieve the purpose of transporting oxygen. |
All goods are packed as required as transportation standard.
1) Each unit machine is skid-mounted construction, connected by fixed-size short pipe. the whole set of plant with all pipes and valve together are delivered to the User's site, the Users needn't to buy any additional spare part by themselves, we ensure the plant's perfect and integrate.
2) The User only need prepare well the workshop, keep the ground level is ok.
3) Adopting liquid oxygen pump inner-compress technology, we can produce high-quality medical oxygen with purity range in 99.6-99.9%. The high quality oxygen products comply with the medical oxygen standard, widely used in medical and industrial area.
4) Complete set of plant is installed without foundation, it has following advantages: stable running, easy operation,
convenient maintenance, without easy-damaged spare parts within two years.
5) To ensure all valves' quality, we adopt the best-quality valve in Air separation Industry produced as the cold-valve in the Rectification column. We adopt stainless steel valve as the Purifier valve, and also install thermostability mat in the stainless steel valve to ensure that the valve is of little wear, no cooling leak, no gas leak, long life in the long-term running.
6) Advanced technology adopted in each unit can reduce power consumption greatly, and save electricity fee at the same time.
7) Complete set of plant could be transported by car easily to suburban and faraway district. That can satisfy customer's oxygen requirements in time in different areas.
8) It only takes about 15-20 days for the installation and commissioning.
9) The pipes used in the Purifier, including the connecting pipes between Purifier to Rectification column are in the conditions of cold-heat changing alternately. The temperature changes range from 5ºC~200ºC. When temperature is low, condensing-water corrode pipe, while the temperature is high, the pipe oxidized seriously. To ensure the life of connecting pipe, and safety of plant, we have made heat insulation treatment on all the pipes.
10) To ensure the safe running of the plant, we equip four-stage pipe oil-filter to ensure that no oil can enter purifier and rectification column. The pressure-difference meter in the four-stage pipe can also show the oil quantity to inform us to change the filter core, ensure the safety of follow-up plant. All filters are equipped with pressure-difference meter, we can judge the degreasing effect and the best time to change filter core, in this way we can prevent oil entering system after the filter core lose efficacy.
