Bag Filter
These range of filters have been designed on the well-known energy efficient Optipulse concept which uses a much lower compressed air pressure of about 2.5 kg/cm2g as compared to the conventional pulse jet filters. The compressed air is directly expanded into the bags, which ensures deeper and stronger pulse cleaning. The filters are fitted with 5 metre and 6 metre bags and larger flow efficient, fast acting 80 NB solenoid valves, which are directly mounted on the tanks, to reduce flow losses to a minimum. This design saves floor space considerably. The Integral valve tank design and low compressed air pressure means lower energy consumption and less bag wear coupled with better cleaning efficiency. The provision of downward gas Inlet and dust pre-collector at Inlet reduces relative dust load while and in-build gas distribution system ensures even load on all bags and higher filter loads. The filters are designed for flows of 5,000 to 100,000 cu/m/hr.
Bag filter pulse cleaned
PANF
Filter type PANF is a high-pressure pulse cleaned filter for dry dust collection in cement, chemical, power, ferrous and non-ferrous industries. This offers the right blend between the quality and economy for the small and medium capacity range. The units are available with bag lengths up to 3.6 meters. The filter is designed for flows from 10,000 to 90,000 cu.m/hr.
PAGF
PAGF is a cyclone bag filter designed for collection of all kinds of dry dust, especially fibrous dust. The combination of cyclone and bag filter enables them to handle a very large dust burden; hence they are also well suited for pneumatic conveying and industrial vacuum cleaning plants. The cylindrical design also makes them suitable for explosive dusts like flour from roller flourmills and coal handling plants. The filters are pulse cleaned and designed for flows from 1,000 to 15,000 cu.m/hr.
PAEA filter shaker cleaned
PAEA
Bag filter type PAEA is a low ratio fabric filter adaptable to a large number of applications. The filter is build up of several rectangular chambers each provided with isolation dampers. Each chamber is provided with a robust shaking gear that is totally accessible from outside. The shaker design ensures very effective cleaning by the stretching and shaking of bags together with simultaneous internal motion. The cleaning programme is carried out by a simple and reliable automatic control system. The filter can be sized for flows ranging from 600 to 1,00,00 cu.m/hr.
PACA filter shaker cleaned
PACA
Cyclone bag filter PACA is a low ratio shaker cleaned unit with a cyclone body designed for dry dust collection systems, especially in industrial vacuum cleaning and pneumatic conveying plants for flow ranging from 500-1900 cu.m/hr. The shaker gear is housed in a separate enclosure and requires almost no maintenance. The filter is available in shop-assembled condition.
Scrubber
A packed bed scrubber is type of absorption tower, which is normally used for removal of pollutant gasses and vapors from air stream. However, in certain cases it can also be considered for removal of particulate matter. Some of the common gaseous pollutants treated by such towers are: Sulphuric acid mist, hydrochloric acid mist, ammonia, formaldehyde and formic acid fumes.
Packed bed scrubbers are mostly counter current scrubbers, which can collect efficiently particulates up to a size of 4-5 microns.
The process is mainly based on the principle that when gaseous stream comes in contact with scrubbing liquid (mostly water) over large surface area of contact of the packing material, the solute (pollutant) gets the scrubbing liquid.
As a result the water coming down the scrubber will gradually become richer in pollutant concentration and ultimately the concentrated liquid goes out from the bottom of the tower. Part of this concentrated liquid is then recycled again to get an optimum concentration level of outgoing liquid through drainpipe, manually. In parallel, the gaseous stream will gradually be depleted from pollutant concentration by filtering media and clean air comes out from the top of the chimney.
