Description
Technical field
The utility model contamination control field, more particularly to a kind of sound coalescence synergy demister of demisting dust removal field,
Suitable for the further dedusting demisting of wet-method desulfurized fume.
Background technology
China obtains the mode of the energy mainly by fire coal, and burning of coal discharges substantial amounts of dust, sulfur dioxide and nitrogen
The harmful substances such as oxygen compound.It is today's society problems faced that these harmful substances are removed before air is discharged into, and is environmentally friendly neck
Endeavour the direction of research in domain.
Power plant takes various flue gas purifying methods now, and the problem of various new is run into exploration.At present, many large-scale electricity
The gas cleaning flow of factory is：Flue gas is introduced into denitrification apparatus and carries out denitration, enters back into electric cleaner and realizes dedusting, then wet
Desulfurization process is carried out in method desulfurizing tower, finally, the flue gas of purification is from smoke stack emission.
Wet desulfuration tower is desulphurization plant, and the washing of desulfurization slurry also has certain dustproof function, but is also possible to simultaneously
Bring desulfurization slurry drop into flue gas, lime stone and gypsum component are contained in these droplets, adds the discharge of particulate matter on the contrary.
The efficiency of wet desulfuration tower defogging equipment influences very big, the general arrangement corrugated sheet in desulfurizing tower outlet on the dust emission of tail flue gas
Demister, but wave-shaped plate demister is higher to the droplet removal efficiency of greater particle size, and it is relatively low to the removal efficiency of fine mist,
Cause part fine mist to enter flue gas, add dust emission.Therefore, in current power-plant flue gas minimum discharge technology, often
Need to set up Wet-electric duster after desulfurizing tower, to reclaim the fine mist that demister is difficult to trap.But this makes gas cleaning
System is increasingly complex, and cost of investment is high.
To sum up, wave-shaped plate demister has the characteristic of " droplet size is bigger, efficiency is higher ", if it is possible to improves corrugated sheet
Droplet size in import flue gas, it is possible to greatly improve the arresting efficiency of corrugated sheet, reclaim most droplets, reduce dust
Discharge, so as to cancel wet electric dust-removing equipment, simplify system, investment reduction.
Chinese patent CN104923403A and CN103706219A are proposed acoustic agglomeration and electric field and spraying synergy
To remove the dust in flue gas, but both approaches are the pretreatments before dust arrester to flue gas, can not improve wet desulphurization
The arresting efficiency of droplet afterwards.Chinese patent CN104307282B discloses the dress that a kind of wet process of FGD coordinates Fine Particles
Put and method, including flue gas desulfurization wash mill, doctor solution washing system, doctor solution circulating pump, acoustic agglomeration device, droplet are caught
Acquisition means and flooding nozzle.The principle of the utility model is that the flue gas after desulfurization is washed initially enters acoustic agglomeration device,
Droplet and fine particle, which are reunited, in the presence of sound wave is grown up, and then, the dust-laden droplet after sonicated is trapped by demister.
But the device is separately provided acoustic agglomeration room, taking up space, big, cost of investment is high, and needs extra installation sonic generator, leads
Cause that complicated, service life is low, energy consumption is big.Chinese patent CN201520502643.6 discloses a kind of manifold type demister,
Including multiple deflection plate blades, multigroup pipe tube bundle and two pieces of supporting plates, pipe tube bundle is installed in baffling passage, passes through circle
The coupling of pipe tube bundle and baffle arrangement, increase the removal efficiency of droplet and fine particle.This method is by changing waveform
Plate flow field improves demister efficiency, limited using sound wave synergy, effect.
In summary, existing demister arrangements are not high to the less liquid mist arresting efficiency of particle diameter, and use sound coalescence skill
When art improves its efficiency, have the shortcomings that reunion chamber size is big, sonic source device is complicated and high energy consumption.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model provides a kind of sound coalescence synergy demister.This is removed
Day with fog does not use sound source loudspeaker to produce sound field, but utilizes aeroacoustics principle, vibrating reed is produced sound field, so as to realize
Sound coalescence, the droplet in flue gas is reunited and grow up, particle diameter increase, by efficient removal in follow-up corrugated sheet, ripple is greatly reduced
The liquid mist content of shape plate outlet.Sound coalescence unit of the present utility model in the same apparatus, saves major part with demisting unit
Space.
Technical scheme is used by the utility model solves its technical problem：A kind of sound coalescence synergy demister, by ripple
Shape plate, vibrating reed unit and support meanss composition.Gas channel, the arrival end of gas channel are formed between the plate of corrugated sheet
Vibrating reed unit is installed, the plate of corrugated sheet with support meanss by being connected to fix.
Described vibrating reed unit is made up of vibrating reed supporting plate and vibrating reed, in a vibrating reed supporting plate
There are multiple vibrating reeds, vibrating reed scatters to supporting plate both sides in an interleaved manner, and when flue gas flows through, vibrating reed vibration produces
High intensity sound wave, generation sound coalescence effect, increase droplet size.
Further, the vibrating reed unit of arrival end can be arranged on the centre of corrugated sheet airflow inlet passage or will vibrate
Reed unit is embedded in corrugated sheet.When air-flow is by vibrating reed unit, vibrating reed vibration sounding, generation sound coalescence effect.
Liquid mist parameter is different in flue gas, and the optimum vibration frequency of sound coalescence is also different, by the length for changing vibrating reed
Spend with thickness to adjust frequency of sound wave.To prevent the corrosion of acid and alkali substance in flue gas, vibrating reed unit is by spring steel or not
The materials such as rust steel are made, and have the characteristics that vibration performance is not good, easy to wear.
The specific defogging method of the utility model sound coalescence synergy demister is：Utilize shaking installed in corrugated sheet entrance
Movable contact spring unit produces sound field, and so as to generation sound coalescence effect, Caragana seed pests occur in sound field for the droplet in flue gas, average grain
Footpath increases, so as to improve arresting efficiency of the follow-up demister to drop.The concrete principle of sound coalescence is：The droplet of different-grain diameter
Inertia is different, therefore different by the degree of acoustic wave entrainment in sound field, produces relative motion between liquid mist, causes to collide, coalescence
Into larger droplet.
The beneficial effects of the utility model are：
(1) sound coalescence principle is applied in demister, sound wave makes liquid mist that coalescence, particle diameter increase, so as to significantly propose occur
The high arresting efficiency of corrugated sheet.
(2) aeroacoustics sounding is utilized, it is not necessary to additional loudspeaker, power supply, power amplification as sound source using vibrating reed
The device such as device and signal generator, it is simple in construction, the life-span is high, reliable operation, and energy consumption is low.
(3) sound coalescence is combined with corrugated sheet demisting principle, the reunion of droplet is grown up and concentrate on ripple with efficient removal
Completed in shape plate, the liquid mist concentration of corrugated sheet outlet is greatly reduced, and can thus cancel the hydrofilter after desulfurizing tower, solves
The problem of space-consuming of having determined is big, cost of investment is high, and simple system is reliable.
