Description
Technical field
The present invention relates to a kind of matrix material and preparation method thereof, particularly a kind of epoxy resin based conductive composite material and preparation method thereof.
Background technology
" fossil-fuel power plant atmospheric pollutant emission standard " GB13223-2011 requires chimney breast soot emissions≤30mg/m after implementing
3, major area≤20mg/m
3after current dust removal installation, in flue gas, fine particle proportion is higher, wet desulfurization system is unstable to the efficiency of dust collection of fine particle, mechanical type mist eliminator can only remove macrobead drop, the desulphurization system of not installing GGH easily carries gypsum slurries again, produce gypsum rain problem, soot emissions all can be caused to exceed standard.
The working conditions of wet electrical dust precipitator is different from dry electric precipitation device, and dust removing effects is better than dry electric precipitation device.The object that wet electrical dust precipitator is removed also has a large amount of water smoke to drip except there being dust granules, because the physical property of droplet and dust exists difference, and its working process also difference to some extent.
From principle, first because the existence of water droplet creates impact to electrode discharge, form emitting ions, the unbound electron in metal electrode must obtain enough energy, and just can overcome ionization energy and cross surface potential barrier becomes electron emission.Electrode surface band water is allowed to be a kind of effective measure reducing surface potential barrier.Behind water covering metal surface, original " metal one air " interface is divided into " metal one water " interface and " water one air " interface, the potential barrier at latter two interface is more much lower than the potential barrier at front a kind of interface, these all change electrode discharge effect, make it at lower voltages corona discharge to occur.Secondly due to the existence of water droplet, after water droplet is combined with dust, the dust specific resistance of high specific resistance is declined, and therefore the working order of wet electrical dust precipitator can be more stable; In addition because wet electrical dust precipitator adopts current to rinse, there is no rapping apparatus, so reentrainment of dust can not be produced.
So after wet electrical dust precipitator is arranged on wet desulphurization device usually, part water droplet is carried in saturated flue gas after desulfurization, by also can catching during high-voltage electric field and being rinsed by water, can reduce like this and always in flue gas carry the water yield, reduce the probability that gypsum rain is formed.Simultaneously for collecting fine particle PM
2.5, acid mist (being of a size of 0.1 ~ 0.5 μm) etc., smoke dust discharge concentration can reach≤10mg/m
3; Solve the gypsum rain problem that wet desulfurization system exists.The PM of wet electrical dust precipitator after the U.S., Japan and Europe have been successfully applied to wet desulphurization
2.5removal.
After wet electrical dust precipitator is arranged on wet desulphurization, flue-gas temperature lower (lower than acid dew point), equipment corrosion problem is particularly outstanding, and stainless material investment is larger.Thus adopt which kind of impregnating material, become wet electrical dust precipitator and need badly and deal with problems.
