In the utility model, filter element is divided into inside and outside two-layer, and inner ring is to imitate filter core at the beginning of filled type formula, and outer ring is
Collapsible efficient filter core, airflow direction are, from air inlet through hollow shaft, to pass radially through just effect filter into after cylindric first effect filter core again
Core, is then passed through efficient filter core, realizes air-polluting double-filtration.
It is of the present utility model to be mainly characterized by：
1. the combined type circular filter is first, efficient filter core integral structure, meets in the case where space limits
The requirement of double-filtration is realized, allow that the volume of cleaning equipment does is less lighter.
2. 3 uniform support bars are designed between air intake end cap and outer end cap, when filter is compressed as intensity
Support to transmit pressure and protect filter core.
3. protecting wire net is designed with the outer ring of the inner ring and efficient filter core of just effect filter core, be effectively protected filter core and be not damaged
It is bad.
4., after filter failure, the nuclear waste of generation is few, post processing cost is low.
The utility model has the advantage of：
1. compound conjunction circular filter is first, efficient filter core integral structure, is compared square under identical nominal air delivery
Filter can obtain less volume.
2. combined type circular filter for just, efficient filter core integral structure, in purification process pollution part be only into
Wind airduct, air intake airduct are directly docked with the air inlet of composite circular filter, and being that purification is up to standard after filter does
Net air, the air-tightness requirement to cleaning equipment are low, also reduce the manufacturing cost of cleaning equipment.
3. the dust containing capacity of filter can be provided using filled type roughing efficiency air filter.
4. filter element adopts columnar structured, and air-flow can make radioactivity gas from jackshaft to entering, radially flowing out
The pollutants such as colloidal sol are all collected at the inside of filter, either make pollution due to vibration in running or when dismantling
When thing departs from filter core, pollutant is also all present and filter interior, will not cause secondary pollution to cleaning equipment or working site.
5. protecting wire net is designed with the outer ring of the inner ring and efficient filter core of just effect filter core, be effectively protected filter core and be not damaged
It is bad.
