In technique scheme, the static nanometer layer of E level filter layer for adopting nano filter medium manufacture to form.
In technique scheme, moistureproof filter layer adopts the synthetic base material of 100% moisture proofness to make.
In technique scheme, high-precision filtration element is that modular type is installed, and dismounting is cleaned separately.
In technique scheme, silencing apparatus adopts metal silk quality muffler material to make.
Compared with prior art, the present invention has following beneficial effect:
(1) high-precision filtration element adopts the double layer construction of E level filter layer, moistureproof filter layer, single-stage is filtered and just can reach the standard of E12 in EN1822-2009, during for the mean particle dia 0.4 μ m of easy penetrating, filter efficiency >99.95%, than like product filter efficiency, improve 5 times, increase the generating output power up to 6%; Can not cause output power loss because compressor pollutes, reduce the pressure loss of upstream device, can reduce equipment attrition yet, reduce fuel consumption, improve thermal effect, and the salinity and the water that effectively contain in filtered air, be applicable to the operating mode operation in high humidity and high salt region-by-region;
(2) adopt single filter to replace original three-stage filtration can reduce occupation area of equipment.
(3) blowback shower nozzle is installed, is improved blowback efficiency, make the filter cylinder life-span extend to 18 months from 12 months, operation pressure drop reduces, and extends the Acceptable life of filter.
(4) built-in inspection platform, reduces operating risk.
(5) adopt the silencing apparatus of metal silk quality muffler material, solve high velocity air and cross muffler material and easily occur floating silk and come off, produce the problem of secondary pollution, the problem of reduction Gas Turbine Generating Units intake air filtrating equipment running noises.
The inlet air that this product is mainly used in the fields such as generating, oil field, petrochemical industry, pipeline transport, naval vessel, railway locomotive gas turbine filters, in energy-saving and emission-reduction, keep the safety in production, cut operating costs and play key effect.
