1. Air Compressor
The air compressor adopts screw compressor. The unit to the box type structure, the host for the import, low noise, whole set of unit, lubrication, electricity, cooling, instrument control into an organic whole, realize the mechanical and electrical integration, intelligent controller with PLC control, touch panel provides all the parameter adjustment and monitoring of the key operation parameters, and there are Chinese and English alternative ways of liquid crystal display, automatic protection, automatic alarm, remote control, many sets of linkage and history and so on the function is all ready, realized unattended continuous operation.
2. Pre-cooling System
Adopt fully closed inlet compressor, refrigerant will never leak, efficient steam separator and inlet automatic drainer, ensure no liquid water in the outlet air. With imported refrigeration components, the equipment can run continuously for years and months with long service life. The remote signal interface of air inlet and outlet temperature and the remote start and stop signal as well as the equipment running fault signal are left on the equipment to facilitate the linkage monitoring of users. The machine is a box structure, no foundation installation, convenient construction.
3. Purifier
The purifier adopts a double-adsorption cylinder structure, one runs and the other regenerates to ensure the air in the column is
clean and the whole fractionator runs longer. To prevent the regeneration temperature from being too high, when the nitrogen temperature at the outlet of the heater is higher than 220ºC, the power supply of the heater will be cut off automatically. When the outlet temperature is lower than 180ºC, the power supply will be switched on automatically. B when the temperature of the regenerated nitrogen reaches 100ºC-110ºC, the heating power will be cut off automatically.(temperature can be set according to the situation)
4. Cooling System
The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration & the cooling is provided by highly efficient turbo expander, which cools the air to temperature almost below -165 to-170 deg C
5. Separation Tower
Oil free, moisture free and Carbon Dioxide free air enters into low pressure fin type HEAT EXCHANGER where the air is cooled below sub zero temperatures by air expansion process in the turbo expander. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification. Oxygen is available at the outlet of the ASU at a purity of 99.6%. Nitrogen is also available t the outlet as a second product at purity of 99.9% up to 3ppm simultaneously without loss of oxygen product.
6. Oxygen/Nitrogen/Argon Gas Compressor
The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 150 bar or up to higher as required. This can be done by liquid oxygen pump is same models. We can use oil & water free compressor.
7. Gas Filling Cylinder The air passes through the air filter, enters the air compressor, compresses to 0.7mpa in the compressor, and then enters the purifier after cooling, where the impurities such as water, carbon dioxide and acetylene in the air are removed. The purified air enters the heat exchanger for heat exchange with the backflow polluted nitrogen. A part of the gas is pumped into the turbine expander through the outlet of the heat exchanger, and the expansion provides a cooling source for the whole set of devices. The other gases continue to cool through the second heat exchanger and then enter the rectifying tower, where they are separated by oxygen and nitrogen. Finally, qualified liquid nitrogen is obtained from the top of the rectifying tower. After decompression by the throttle valve, the liquid air at the bottom enters the condensing evaporator at the top of the tower and the nitrogen heat exchange at the top of the rectifying tower, and then passes through the cooler, the second heat exchanger and the main heat exchanger cooling box as the regenerative purifier.
