Purpose and area of application
The electrofilter is used for cleaning of air or other neutral gas from any industrial dust with concentration up to 40 g/m3 and it can be installed both indoors and outdoors. This electrofilter can be used for air cleaning at enterprises of ferroconcrete items, wood-processing industry etc. (for cleaning of air from fine-dyspersated dust: up to 1 µm and lower).
Advantages
in comparison with the most widespread hose suction filter (SMC -166) the proposed electro-filter has:
- high degree of cleaning - 98,5 % against 95 % (dust-priming was reduced in over 3 times);
- low working costs (electrofilter is not become clogged with dust as in it there is no filtering material, and regeneration is made automatically by shock-hammer shaker);
- low power inputs per unit of treated gas (0,2 kWt*h on 1000 m3 of gas against 0,4 kWt*h);
- possibilities of cleaning of practically any powder-gas flows independent on moisture and specific electrical resistance of hard phase.

Construction The electrofilter consists of three units: chambers for precipitation of dust, high-voltage power supply and shaker unit. The chamber for precipitation of dust represents a package from six rectangular airway section 0,2*1,2 m and length of active zone - 2,2 m. Inside each of six sections is located the corona-forming electrode, to which the high voltage is brought. Regeneration of the filter is carried out automatically by shock-hammer shaker.
Implementation
- pre-production model of the electrofilter intended for trapping of cement dust was made and maintained on "Novopolotskghelezobeton" plant;
- laboratory electrofilter with productivity of 1000 m3/h was made for demonstration and educational purposes.
Proposals
- drawings of details and units;
- technical help at manufacturing and starting-up and adjustment works;
- manufacturing the electrofilter within one year from the moment of financing;
- follow-on at operation;
- joint production and realizations of electrofilters.
