Description

A kind of wet-esp two-level absorption tower
Technical field
This utility model relates to dedusting technology field, is specifically related to a kind of wet-esp two-level absorption tower.
Background technology
Nowadays the more of dedusting technology is exactly bag-type dust and electric precipitation, and electric precipitation can be divided into again dry type, half dry type With wet type these three.Wet electrical dust precipitator is identical with dry electric precipitation device operation principle, is all to bear to electric field space conveying direct current High pressure, is ionized by space gases, in flue gas after dust granules and droplet charging particle under the effect of electric field force, moves to receive Dirt pole plate (colelctor electrode), thus it is collected in dust collector pole surface.Dry electric precipitation device utilizes vibration dust-cleaning mode to collect Dust shakes off in ash bucket, and wet electrical dust precipitator is then by collecting the droplet granule in flue gas, is formed on dust collector pole surface Overflow and dust is flushed in ash bucket (water ash bucket).Wet electrical dust precipitator is different from dry electric precipitation device maximum, is cigarette The difference of gas working medium, dry electric precipitation device flue gas is dry flue gas, and flue-gas temperature is higher, is substantially free of droplet in flue gas.And wet type Electric cleaner is wet saturated flue gas, and flue-gas temperature is relatively low, containing substantial amounts of droplet in flue gas.Wet electrical dust precipitator is generally arranged at After wet desulphurization device, saturated flue gas is carried after desulfurization a large amount of water droplet, captured when by high voltage electric field, it is possible to reduce stone The probability that cream rain is formed.Having preferable effect simultaneously for collecting fine particle PM2.5, acid mist etc., smoke dust discharge concentration can To reach≤10 milligrams/cubic metre.
Summary of the invention
This utility model purpose is to provide one to remove than existing wet dust removal absorption tower dust removing effects more preferable wet type electricity Dirt two-level absorption tower.
This utility model for achieving the above object, adopts the following technical scheme that
A kind of wet-esp two-level absorption tower, including tower body, described tower body top has smoke inlet, and its feature exists In: be disposed with from top to bottom in described tower body deflector, one-level shower, Wet type electric dust-removing device, two grades of showers and For intercepting bulky grain flue dust and adsorbing the conduction purification grid of grit droplet;Sewage mouth it is provided with bottom tower body.
It is further characterized by described conduction and purifies grid is electro-conductive glass steel grating plate, has the square of regular distribution Shape and square space.
Preferred: described Wet type electric dust-removing device includes high-tension porcelain insulator, electric discharge coil holder, many discharge lines, dust legs and weighs Hammer;Described high-tension porcelain insulator is arranged on electric discharge coil holder two ends, is used for connecting high-tension electricity;Described many discharge lines one end are evenly distributed on On electric discharge coil holder, the other end hangs with weight;It is provided with dust leg in every discharge lines.
Described one-level shower and the NaOH solution that spray liquid is 5% of two grades of showers.
The advantage of this utility model wet-esp two-level absorption tower:
1, use novel corrosion-resistant composite as dust leg, modular construction, honeycomb arrangement, can effectively utilize sky Between, Flow Field Distribution uniform.Corrosion-resistant, electric discharge strength is stable, makes equipment voltage, electric current be in higher parameter, thus ensures relatively Good dust removing effects.
2, novel corrosion resistant composite is used to make electric precipitation (mist) device structure flexible arrangement, it is possible to adapt to current complexity Transformation place, can individually be arranged in desulfurizing tower and export at clean gas flue, it is possible to be arranged in desulfurizing tower tower top, or be individually arranged in The vacant lot that power plant's site condition allows.
Need not spray into continuously alkaline water when 3, running, rely on electric field region to collect flue fog drip, formed in dust leg Overflow, reaches the purpose of gravity flow deashing.
4, wet electrical dust precipitator is one of current state-of-the-art PM2.5 control technology, can reach following performance indications:
Power consumption little (300,000 ten million unit power consumption≤300 kilowatt), resistance low (≤350 handkerchief)
Subparticle removal efficiency is high.PM2.5 concentration of emission≤1.5mg/M3, granular material discharged concentration≤10mg/M3.
Aerosol and sulfur trioxide removal efficiency 60%.
Heavy metal Hg removal efficiency about 40%.
Droplet clearance 85%.
5, newly-increased conduction purification grid makes gas carry out final dusting.Increase this purification grid, it can be ensured that high concentration Flue gas is by exiting flue gas≤5mg/M after this equipment3
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As shown in Figure 1: from top to bottom, flue gas passes through deflector 2 to the smoke inlet 10 at flue gas tower body 1 top, makes gas equal Even distribution.Being sprayed by one-level shower 3, spray uses the NaOH solution of 5% again, enters back into dedusting region by wet type electricity Dust arrester carries out dedusting.Described Wet type electric dust-removing device includes high-tension porcelain insulator 4, electric discharge coil holder 5, many discharge lines 6, dust legs 11 and weight 7;Described high-tension porcelain insulator 4 is arranged on electric discharge coil holder 3 two ends, is used for connecting high-tension electricity;Described many discharge lines 6 one end Being evenly distributed on electric discharge coil holder 3, the other end hangs with weight 7;It is provided with dust leg 11 in every discharge lines 6.At high-tension electricity Under effect, in dust leg 11, create corona current and electric field intensity.Under the effect of electric field force, the grit in gas completes Charged, mobile, sedimentation, flushing process, in gas, charged grit moves to dust leg 11, and gas is detained in dust leg 11, transports Row obtains dedusting, gas outlet of finally going directly, be absorbed in the grit of dust leg 11 wall by the flushing of spray liquid after, pass through wet type The sewage mouth 9 of dedusting absorption tower is discharged.Through the flue gas of Wet type electric dust-removing device after two grades of showers 3 spray, the most past Under by conduction purify grid 8, carry out final dusting.It is electro-conductive glass steel grating plate that conduction purifies grid 8, uses molded Technique make with the many rectangle of regular distribution, the polyester sheets in square space, there is the mechanical characteristics of the two-way same sex.Should Conduction purifies grid 8 and can intercept bulky grain flue dust and adsorb certain grit droplet, and the grit of absorption can pass through spray liquid Rinse to dirty.Sewage sewage mouth bottom absorption tower is discharged.
This utility model is through final dusting, it can be ensured that high-concentration fume is by exiting flue gas≤5mg/ after this equipment M3
