[0004]With the rapid development in the industrial and commercial society, environmental pollution is getting worse. Because human beings haven't taken effective measures to improve the environment while natural calamities has resulted in the change of ecological environment, which threatens lives of human beings.
[0005]There are many sources causing air pollution. Waste gas is produced mainly from factories in addition to transportation vehicles. To reduce effectively the amount of waste gas, the method adopted recently is to use a processor for releasing into air only the waste gas where the amount of pollutants are lower than the standard values.
[0006]Waste gas mainly contains granular or gaseous pollutants, which have to be processed in different ways. For example, when waste gas containing granular pollutants is to be processed, a dust collector is usually used in the field. The dust collector is provided with a bag filter therein for separating gas and micro granules after the waste gas is suctioned into the dust collector. The micro granules are filtered, collected and thrown away, or reused, and the gas is released via a venting apparatus.
[0007]In practice, the bag filter can be in rectangular or cylindrical shape when used in different dust collectors. Structurally, the bag filter comprises a supporting frame of rectangular or cylindrical shape and on the exterior of the supporting frame is covered with a filter. Although the described structure can be used for separating gas from micro granules effectively, there are still several disadvantages need to be improved.

[0014]Another object of the present invention is to provide a peaky filter, wherein the filter is in multifold shape and positioned on the exterior of the supporting frame for occupying less space while the total filtering area is maintained.
[0015]A further object of the present invention is to provide a peaky filter, wherein two ends of a plurality of positioning rods are connected with upper and lower positioning pieces respectively for fastening or releasing the two ends of the filter, so that the filter can be easily replaced to save operation cost.
[0016]In order to achieve the above objects, the present invention provides a peaky filter comprising a covering and a corresponding base, a supporting frame, and a filter. The covering is provided with an air vent. The supporting frame is disposed between the covering and the base and includes a plurality of transversely spaced first supports and a plurality of connectors. Each support has a supporting rod and a plurality of supporting members longitudinally spaced and connected to the supporting rod. The supporting member has a first supporting leg and a second supporting leg outwardly and radially from the supporting rod. Each connector has a first connecting part and a second connecting part for respectively connecting one end of the first supporting leg of one support and one end of the second supporting leg of another adjacent support. The filter is in multifold shape and positioned on the exterior of the supporting frame.
[0017]In practice, the connectors are in U-shape or H-shape.
[0018]In practice, the present invention further includes a plurality of transversely spaced positioning rods for connecting the longitudinally spaced connectors respectively. The two ends of each positioning rod are connected with an upper and lower positioning pieces for fixing the filter.
[0019]In practice, the upper and lower ends of the filter are disposed with at least one pressing sheet respectively, and the upper and lower positioning pieces are springs for pushing the connector to press against and fix each pressing sheet.
