The invention relates to a system for preparing oxygen-rich air through a negative pressure technology. The system comprises an air filter, a ventilator and a membrane device, the air filter, the ventilator and the membrane device are sequentially connected, the system also comprises a vacuum pump, and the vacuum pump is connected with the low pressure side of the membrane device. A method for preparing the oxygen-rich air through the negative pressure technology comprises the following steps: 1, air goes through the air filter; 2, air is conveyed into the membrane device; 3, air moves from a high pressure side to the low pressure side under the driving of a differential pressure; 4, oxygen preferentially passes through the membrane device due to different penetration rates of nitrogen and oxygen passing through the membrane device, nitrogen is separated from the high pressure side, and oxygen-rich air is formed at the low pressure side; and 5, the low pressure oxygen-rich air is compressed through the vacuum pump to convert compression energy into heat energy in order to finally form normal-pressure moderate-temperature oxygen-rich air, and the oxygen-rich air is injected into a kiln through an oxygen-rich nozzle. The system and the method have the advantages of reduction of energy consumption in the oxygen-rich air preparation process, simple pretreatment, convenient and safe operation, and reduction of maintenance needing devices.
Description
