Shri Krishna Vacuum System


The technology on which this collector works, is the advanced technology of electrostatic precipitation with periodic de-dusting facilities. The size of the units that can be made ranges from 300cfm to maximum 6000cfm. The dust collectors have some technical features which include: a unique double pass, cross-configuration design to achieve optimum dust collection efficiency-even submicron size particulate dust. The dust trapping is carried out by electrostatic force. Therefore, there is negligible pressure drop across the unit by which there is a power saving of 25% to 30% as compared to the same size bag or cartridge type dust collectors. The dust collecting elements are metallic, cleanable and reusable for a long period of time.

Shri Krishna Pulverisers manufactures Pneumatic system dust collectors have following which include:-

  • dust-laden air is drawn into the dust collector through an inlet due to suction created by an suction impeller and passes through filter cartridge elements;
  • abrasive-resistant inlet promotes the dropping out of highly particulate matter and generates uniform air flow, thus increasing filter life;
  • On the outer surface of the cartridges dust gets deposited and clean air flows through the centre of the cartridge into the clean air plenum.
  • There may be two option (1) dust can be separated by the electromagnetic dust collector (2) dust can be dissolved in a water source.

Shri Krishna Pneumatic systems offers dust collection systems. Air along with dust particles under suction or pressure enters the lower portion. The air travels through the filter bag, which retains the dust particles on surface of the bag, and the clean air passes out through bags and plenum to the outlet of bag filter. Dust collected on the outside of the filter of the bag filter.

To control the pressure differential across the bag filter, a sequential bag causes an increase in the pressure differential between dirty and clean air. Side timer actuates a series of normally closed pulse valves at preset intervals causing them to open.

A momentary rush of high-pressure air [4-5 bar g] flows from the compressed air header to the blow pipe and is expelled from the blow pipe through nozzles at high velocity [primary air flow]. Air from each nozzle induces a secondary airflow. The combined effect of the primary and induced secondary air causes an instantaneous pressure rise on the clean side of the filter bags, causing a reverse flow air through filter bags, thus dislodging the dust particles held on the outer surface of the bags.
