The Fresh Air from Industrial Dust Collector


Recently,pure air has become quite rare. Pollution levels at all timehigh and continues to grow. Fortunately, newtechnologies, such as a device for dust collecting systems are available tohelp stop air pollution. The air was polluted by continuous industrialprocesses. Dust collectors work with filter dirtfrom the poisoned work environment. The quality of dust collectors can protectworkers and the rest of society from the impact of environmental pollution. Useit to help various companies in accordance with health and emissions standardsthey must meet. Possession of dust collectors attracted interest in yourbusiness.
The principle of collection relies on the ability to impart a negative charge to particles in the gas stream causing them to move and adhere to the grounded or positively charged collector plates. Most precipitators are made for horizontal air flow with velocities 100 to 600 fpm.
- Fabric Collectors
Fabric arresters are high efficiency, medium cost collectros. Dust collection is obtained by building up a mat of the material on the dirty side of the media. This mat provides the actual filtering or straining bed. By means of this bed a high degree of removal is obtained even on submicron size particles.
- Intermittent-Duty Fabric Collectors
These types may use either envelope or stocking arrangement of the fabric but will generally employ shaking or vibrating as a means of reconditioning. Periodically Uusually at 4 to 6 hour intervals0 the air flow must be stopped to effect reconditioning - thus the classification 'intermittent'. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like vibrating feeder, Henan Hongxing is always doing the best in products and service.
- Multiple-Section, Continuous-Duty, Automatic Fabric Collectors
The disadvanteges of stopping the air flow to permit vibration and variations in the airflow can be overcomed by using of sectional arresters allowing continuous operation of the exhaust system as automatic dampers periodically take one section out of service for reconditioning the fabric while the remaining sections take the entire gas volume.
- Reverse-Jet Fabric Collectors
The reverse-jet type differs from the conventional arrsters in its use of high pressure air to clean the fabric. One type uses high pressure air (30' - 40' WG) froma travelling 'blow ring' to dislodge the collected cake from inside the fabric tube. Another type uses high pressure compressed air (100 PSI) to break the dust cake from the exterior of the fabric tube or envelope by the intermittent application of reverse-jet compressed air.

For abrasive or corrosive applications, special cmaterials of construction are available, such as abrasion resistant carbon steel, stainless steel, special alloys, rubber liners, etc... Many sizes and arrangements of cyclone dust collectors are available from Canadian Air Systems to meet specific capacities and space requirements.
