Description

The preparation method of air dust centrifugal purifier and rotary filter net disk thereof
Technical field
The present invention relates to the air environmental pollution prevention and control field, refer to the preparation method of a kind of air dust centrifugal purifier and rotary filter net disk thereof particularly.
Background technology
In recent years, the national economy of China increases fast, has driven industry develop rapidlys such as manufacturing, food and drink, has brought unprecedented prosperity to urban economy on the one hand, but has also brought serious pollution to atmospheric environment simultaneously.The atmosphere pollution closely bound up with common people's daily life is mainly reflected in following three aspects: the first derives from the oil smoke in family kitchen and food and drink hotel, these oil smoke that contain a large amount of volatility material are drained in the air directly or indirectly, are quite lasting to the pollution that atmosphere caused; It two is to derive from the flue dust that various manufactories, processing factory and chemical plant are produced, and contains a large amount of harmful substances such as sulfide in these smoke exhaust, and is unprocessed or just directly be discharged in the atmosphere through simple process, very big to the infringement of health; It three is the ventilation air interchange systems that derive from megastore, enterprises, its operation principle is that the direct suction of outdoor fresh air is indoor, if contain nuisances such as a dust or a material in the outdoor air, then room air just can be subjected to pollution inconspicuous, and chronic pollution year in and year out is even more serious to the infringement of health.
Along with the enhancing day by day of numerous common people's environmental consciousness, also more and more higher to self and environment requirements, the control of air environmental pollution has become the task of top priority.At present, the scientific research personnel has developed the air cleaning unit of multiple versions such as electrostatic, showering, active carbon formula, mechanical type, rare earth formula in succession.
The principle of electrostatic air purifier is to utilize that formed electric field comes the ionization oil smoke between the high-field electrode.Because the temperature and humidity of oil smoke is in frequent variation, electrode also is easy to be stained with grey incrustation, causes the electric field pole instability, makes its purification efficiency not only lowly but also unstable.Also there are secondary pollutions such as electromagnetic pollution, interference video in it simultaneously.The grease of electrodes need frequently be taken cleaning apart in addition, and maintenance workload is big, and maintenance requires high, and the frequent replacing of battery lead plate also causes cost to increase.
The principle of showering air cleaning unit is the water that contains washing agent by the water pump pressurization, its atomizing back is contacted with oil smoke absorb oil smoke.This purifier structure is comparatively complicated, must keep in repair the special manufacturer when being out of order, and maintenance workload is big, and the oil smoke coagulum often is insoluble in water, except that blower fan and water pump power consumption, the consumption of water, washing agent, absorbent is also more, thereby its efficient is on the low side, cost is higher.The waste water that contains greasy dirt, washing agent simultaneously also can cause secondary pollution.
The principle of active carbon formula air cleaning unit is to utilize active carbon that smoke particle is adsorbed.Though its use cost is lower, safeguard also easily, after using, it still has in a large number by the residue of oil pollution, and its service life is also shorter, is eliminated by market.
The principle of mechanical air purifier is to utilize a pair of convex-concave pole plate net that smoke particle is carried out mechanical interception.But because viscosity height, the resistance of smoke particle are big, not only oil fume pump exhaust is not smooth, and frequency height, the workload of clean and maintenance are big, use cost is higher, and country has not allowed it to pass through to detect.
The principle of rare earth formula air cleaning unit is to utilize aluminium oxide to mix the rare earth particle smoke particle is adsorbed.Though it does not need consumed power, need periodic replacement alumina catalyzation bed and rare earth particle, safeguard that frequently use cost is too high.Windage during its operation simultaneously is bigger, and purification efficiency is not high yet.
