In this embodiment, the face type of above-mentioned spoke side or reflection end is concave surface or plane, be will not be repeated here.
In order to make it easy to understand, it is following provide it is several it is of the invention based on sound wave except the application scenarios of haze device：
(1) by being arranged on except haze device in the ventilation shaft in building based on sound wave, air inlet is purified；
The height of supporting plate 3 is designed according to the height of pipeline so that device can be placed on inside ventilation shaft, and caused
Spoke side loading plate 1 is close to the top of pipeline, and reflection end loading plate 2 is close to the bottom of pipeline, between supporting plate 3 and inwall continuously
Gap.Purpose is to reduce air flow in the gap of pipeline and equipment, allows in more air slave units and flows.Spoke side is carried
Power supply is powered to PZT (piezoelectric transducer) in plate 1, and PZT (piezoelectric transducer) converts electrical energy into mechanical oscillation, and is put amplitude by ultrasonic transformer
Greatly, conduction sends sound wave to spoke side array 4.
What is faced with spoke side array 4 is reflection end array 5, and reflection end array 5 is arranged on base, spoke side array
It is resonator between 4 and reflection end array 5, spoke side array 4 launches sound wave to reflection end array 5 vertically downward, and sound wave is through anti-
Penetrate end reflection to upwardly propagate, two beam sound waves form standing wave in resonator.Due to the effect of restoring force, PM2.5 particles can change
Its original movement locus is gathered in standing wave node neighbouring position.
Due to the molecule for getting in, without high-power, the amplitude of sound wave is set to 20dB.Ventilation shaft
0.5 meter or so is highly generally, spoke side loading plate 1 and bottom 2 is removed, the length of resonator is 0.3m or so, therefore sound wave
Wavelength have to be greater than 1.2KHZ less than 0.3m, i.e. frequency.Ventilation shaft is indoor equipment, to consider noise on human
Influence.Human auditory system scope 20HZ-20KHZ, it is therefore desirable to by set of frequency in more than 20KHZ.And the higher sound wave of frequency its
Wavelength is shorter, and the standing wave quantity so produced in limited resonator is also more, so that branch collection pipe at the node needed
12 quantity is more, and excessive branch collection pipe 12 can influence ventilation effect, therefore frequency needs to be arranged on a rational model
In enclosing.By calculating, set of frequency is more reasonable into 25KHZ.
In theory, the diameter of spoke side and reflection end is smaller, and density is higher, so that the standing wave produced is more intensive, it is contemplated that
A diameter of 10mm of production technology and cost, design spoke side and transmitting terminal；End face can be plane or concave surface simultaneously；It is recessed
During face, radius of curvature is 27mm.
Therefore, should be based on sound wave except the parameter of haze device is that the length of supporting plate 3 is 40cm-50cm, spoke side array 4
With the diameter 10mm of reflection end array 5, the pipeline open height of branch collection pipe 12 is 2mm, and length is 1.5m, and total collecting pipe 13 is wide
1cm, long 40cm, the non-woven bag that end connects a diameter 10cm is the purpose that can reach demisting haze.Non-woven fabrics need to only be determined
Phase cleans, you can reuse, therefore present apparatus no material consumption.
Further, if the array is arranged at air inlet, the end of total collecting pipe 13 can be gone to air inlet
Side, particle is discharged in outside air, can be discharged again after particulate matter is again introduced into device, this ensure that into pipeline
The quality of interior air, saves the trouble of periodic cleaning non-woven fabrics dust settling pocket, can be with long-term stable operation.
(2) by being arranged on except haze device near the throat of the factories such as power plant, chemical plant, cement plant based on sound wave
Place, is purified to industrial waste gas；
According to the height of the diameter design supporting plate 3 of chimney, it is necessary to squarely will be reequiped near chimney outlet, facilitate spoke
Penetrate end loading plate 1 and be close to inner wall of stack with reflection end loading plate 2, supporting plate 3, reduce air and flowed in the gap of inwall and equipment
It is dynamic, allow flowing in more air slave units.Power supply is powered to PZT (piezoelectric transducer) in spoke side loading plate 1, and PZT (piezoelectric transducer) will
Electric energy is converted to mechanical oscillation, and by ultrasonic transformer by Amplitude amplification, conducts to spoke side array 4, send sound wave.
What is faced with spoke side array 4 is reflection end array 5, and reflection end is arranged on reflection end loading plate 2, spoke side
It is resonator between array 4 and reflection end array 5, the level of spoke side array 4 launches sound wave to reflection end array 5, and sound wave is through anti-
Penetrate end and be reflected towards spoke side propagation, two beam sound waves form standing wave in resonator.Due to the effect of restoring force, PM2.5 particle meetings
Change its original movement locus and be gathered in standing wave node neighbouring position.
Due to containing substantial amounts of particulate matter in the waste gas in factory, it is necessary to as soon as possible by particulate matter capture, it is necessary to high-power,
Again because chimney breast is higher, the life of the sound wave of high-decibel on the mankind influences little, and the amplitude of sound wave is set to 80dB.100m
High chimney, exit diameter is typically no less than 3.5m, and spoke side loading plate 1 is left in 2.47m with the distance of reflection end loading plate 2
In the right side, the chimney that 100m is arranged on due to equipment, therefore the influence of noise need not be considered, it is necessary to which what is considered is branch collection pipe 12
Influence to exhaust gas flow, therefore its quantity should not be too many, it is that 1KHZ is more reasonable to set frequency of sound wave.
