Description
Technical field
It is higher or containing small for being atomized viscosity more particularly to one kind the present invention relates to a kind of liquid dispensing apparatus
The supersonic atomizer of the suspension of solid particle is particularly suitable in Coal,steam plant with FGD denitrating system, belongs to
Ultrasonic atomization field.
Background technique
Sulfur dioxide is a kind of gaseous pollutant that quantity is larger in current atmosphere pollution, coverage is wide.With people
The rapid development of class society, the demand to the energy are growing on and on.This is doomed problem of environmental pollution will increasingly acutely, and power plant consumes
A large amount of coal generates a large amount of sulfur dioxide, therefore power plant desulfurization is the important means for protecting environment.Power plant mostly uses greatly at present
Wet desulfurizing process.The slurries produced in the technique are sprayed through atomizer and smoke contacts, to achieve the purpose that desulfurization.Spray
Mouth is one of the critical component in desulfurizer.Atomization is that liquid or liquid-solid suspended substance are dispersed into the operation of fine droplets grain, it
Huge alternate contact area can be provided, be a kind of important unit operation.Nozzle atomization performance quality to desulfuration efficiency,
Cost of investment and operation maintenance cost have important influence.Wet desulphurization atomizer is generally pressure nozzle at present, can divide
For solid-cone, hollow cone and fan-shaped cone, nozzle arrangements are relatively simple, and atomizing effect is bad.In order to further improve atomization
Effect also needs to consider emphatically the Optimal Structure Designing to nozzle and the development and application of novel atomized device, is improving desulfuration efficiency
While, cost of investment, Operation and Maintenance cost are reduced, desulphurization cost and energy consumption are reduced.
Ultrasonic fog is turned to the novel liquid atomization technique of one kind and is widely used in medical, civilian, industrial, scientific research etc.
Every field.Ultrasonic atomization is that the higher-order of oscillation issued using ultrasonic transducer is torn the liquid in transducer face
At small particle.Ultrasonic atomized water droplet diameter is small, partial size < 50 μm.It is big with gas-contact area, convenient for atomized steam with
Flue gas comes into full contact with mixing, effectively progress depickling.In addition to this, ultrasonic atomizatio evaporation rate is high, can make dust-laden region water vapour
It is rapidly reached saturation, is not only able to satisfy condition required for improving respirable dust wettability, moreover it is possible to pass through cloud physics, air
A variety of mechanism such as dynamics, stefen flow conveying realize the trapping of " respirable dust ".
And existing supersonic atomizer is suitable only for the single phase soln such as atomized water, alcohol.And in unloaded (aneroid
Body) when, inefficient higher-order of oscillation energy converter can be warming up to 200 DEG C or more moment, cause energy converter to burn, so this kind
Supersonic atomizer must be completely immersed in liquid and work, so that the atomising device be made to usually require a tank and can only
It is atomized from bottom to up, only liquid mist could be blown into other directions, this defect by applying certain directing gas flow
This kind of atomising device is allowed to be very limited in many practical applications.
And the calorific value of generally taller and bigger energy converter when 40KHz, work of vibration frequency of existing ultrasonic atomization spray head
It is higher, wherein most of energy converters work as running hours, energy converter are easily caused to cross cause thermal damage again without good heat sinking function,
Needing to frequently replace energy converter can just work on, and dally over one's work the time, directly affect working efficiency.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of ultrasonic fog for suspension
Makeup is set, and is particularly suitable in Coal,steam plant with FGD denitrating system, overcomes existing atomising device easily to block, spraying granule
Greatly, calorific value is big, it is necessary to which the harsh operating conditions being completely immersed in liquid, the device can not be needed frequently more with continuous work
Energy converter is changed, and the suspension in addition to solution can be atomized.
The object of the present invention is achieved by the following technical solutions.This ultrasonic fog for suspension is disguised
It sets, it includes transducer housing, energy converter, atomization tool heads, liquid spraying ring, air inlet, venthole, inlet opening and fluid hole, institute
It states transducer housing to be coated on outside energy converter, energy converter connects ultrasonic wave electricity by the wire interface on transducer housing top
Source；The atomization tool heads are connected with energy converter, and energy converter is snapped connection with liquid spraying ring；It is provided with out in transducer housing bottom
Stomata, the gap between transducer housing and energy converter are filled with heat-conducting glue；The air inlet is placed in transducer housing top, pressure
Contracting air is entered inside transducer housing by air inlet, compressed air in the intracavitary quick flowing of transducer housing, and from go out
Port discharge, takes away heat caused by transducer vibrations in cavity with this；The side of liquid spraying ring is arranged in the inlet opening, uses
In the pumping liquid into liquid spraying ring；The liquid spraying ring is fixed by the baffle of two pieces of middle with hole, and is sealed and connected under shield
It connects to prevent liquid leakage, liquid spraying ring has the liquid storage groove of a ring circumference to communicate with inlet opening, pumps for storing into liquid spraying ring
Liquid to be atomized, macropore form spurting under conditions of holding differential pressure and liquid level difference into the atomized liquid that aperture goes out.
The venthole is to guarantee that energy converter ventilation is cold along two long and narrow band-like gaps that energy converter outer symmetrical is distributed
But it avoids generating interference to the ultrasonic atomization in atomization tool heads because of air-flow end difference while, influences atomizing effect.
The fluid hole is arranged on the circular conical surface of liquid spraying ring bottom end, and the diameter for the distribution of 8 ring even circumferentials is 1mm's
Small micropore, the liquid that fluid hole sprays reaches exactly on the chamfering section of atomization tool heads, when liquid injection arrives fast vibration
When being atomized on the chamfering section of tool heads, one layer of wavy fluid film just will form on the chamfering section of atomization tool heads, with
The increase of atomization tool heads Oscillation Amplitude, the amplitude of liquid film surface wave also increases.
The axial direction of the center of the fluid hole and the line of atomization tool heads bottom center and atomization tool heads is at 30 °.
The invention has the benefit that the present invention is by adopting the above-described technical solution, improve supersonic atomizer
Atomization ability and nebulization efficiency；The suspension and solution atomization that may be implemented, and supersonic atomizer of the present invention
It is not limited by body fluid storage and liquid level, it can also be spraying to any direction in the case where no water conservancy diversion wind；Overcome existing machinery
The problems such as spray head easily blocks, spraying granule is big, the spray head can not need frequently to replace energy converter with continuous work, send out in firepower
Means of flue gas desulfurization of power plant denitrating system field has broad application prospects.
