Working principle:
Industrial oxygen production equipment. Industrial oxygen generator is a set of air separation equipment that can extract oxygen and nitrogen from the air simultaneously . It is a new type of process flow with a turbine expander. The purified incoming air exchanges heat with the reflux gas in the main heat exchanger and it is gradually cooled into saturated air with a small amount of liquefaction , then entering into the lower column for distillation. Distillation is the process of obtaining pure oxygen and nitrogen through multiple partial evaporation and condensation in the distillation column by utilizing oxygen and nitrogen of different boiling points. The function of the lower fractionation column is to produce liquid air and liquid nitrogen. The function of the main condenser evaporator is to evaporate liquid oxygen and condense gas nitrogen at different pressures under low pressure, while the function of the upper fractionation column is to obtain product oxygen and nitrogen.
Features of the system:
* The process is newly developed and designed.Our company can use this technology maturely.
* The device can operate simply and maintain conveniently. It has short start-up time and low energy consumption.
* The oxygen has high purity and very stable, which meets and exceed the technical indexes GB8982-1998 of the journal of medical oxygen.
* The complete plant adopts air- cooled method and it do not need to use water, which is adaptable and save the cost.
* Good safety - the external compression process adopts oxygen to be compressed in the form of gas at room temperature, while the internal compression process uses liquid oxygen to be compressed in the form of liquid at low temperature. The internal compression process has higher safety performance and the main cooling system extracts a large amount of liquid oxygen to ensure that hydrocarbons do not accumulate.The high evaporation pressure of liquid oxygen reduces the possibility of hydrocarbon accumulation.Reduce fire hazards.
* High reliability- the liquid oxygen pump has high performance and simple maintenance.
