【 摘 要 】

Owing to the special request of environment and closeness, for example the underground structure, communication engineering and the forth, there are a lot of air pollutions (sulphur dioxide, nitrogen oxide and carbon monoxide, etc.)In the close and half close space. The air pollutions harm the health of the internal persons seriously. This topic studies all kinds of air purification modes, design the combined purification craftwork (photocatalytic oxidation, plasma and adsorption techniques) for underground engineering air pollution, develops a suite of combinational air purifying device, and finally conducts the performance test. The conclusions are obtained as follows: (1) the combinational air purification device has excellent treatment effect on the formaldehyde and CO gas. When the gas mixture goes through the photocatalytic oxidation module and the plasma module simultaneously, and then the adsorption module finally, the degradation rate of formaldehyde is up to 91.8%; in addition to separate activated carbon treatment, other treatment modes of the device are capable of purifying the CO gas, the purifying rate is between 77%∼87%.(2)The combination air purifying device provide the hardware support for evaluation of the effectiveness of high efficient purification materials and combination of air purification process during engineering application.
