Background technology
Based on condensed oil sewage purification softened water, impurities in water is more for uphole steam generator feedwater, chlorion and sodium, potassium from
Sub- content is high.After boiler feedwater enters drum, due to the continuous evaporation of saturated vapor, stove water is constantly concentrated, and is held in pot water
The concentration of the material of water surface foaming is easily caused also to increase therewith, if blowdown not in time, Yi Fa after concentration increases to a certain extent
Raw priming, forms a large amount of foams on carbonated drink interface.In addition, load increase is excessive too fast in operation, make drum pressure wink
Between reduce, priming phenomenon can also occur.During generation priming, carbonated drink boundary is difficult to distinguish, and waterline is anxious in liquid level gauge
Play is fluctuated, and water level is shown incorrect in drum, easily causes Boiler Water Shortage Accidents；Superheat steam temperature is decreased obviously, and influences boiler
Efficiency；Saturated vapor carries a large amount of pot water, and influences steam quality dissolved with a variety of salts substances in pot water, and equipment is caused to damage
Evil, can occur water slug in jet chimney when serious.In order to ensure the safety of drum and water-cooling wall in operation, ensure normal raw
Production, in addition to the salt ionic concentration in feedwater and pot water is controlled by, it is necessary to take when priming occurs and effectively arrange
Apply, foam of the elimination in time caused by because of priming on carbonated drink interface.For this reason, it may be necessary to develop one kind be swift in response, simply,
Efficient and economic boiler-steam dome is to tackle the generation of priming phenomenon.
Utility model content
In order to prevent being endangered caused by equipment because of priming phenomenon in boiler-steam dome, ensure boiler efficiency and operation
Safety, the froth bed on carbonated drink interface is eliminated in time and efficiently, the utility model proposes a kind of with ultrasonic wave defoaming device
Boiler-steam dome, the utility model are not only simple in structure, it is easy to accomplish, and good defoaming effect can be reached.
The technical solution of the utility model is as follows：
A kind of boiler-steam dome with ultrasonic wave defoaming device, the drum are provided with feed pipe, vertical downcomer tube, blow-off pipe
With steam fairlead；Liquid level gauge and water separator are provided with drum；It is characterized in that：One is installed in the drum
Or multiple ultrasonic generators；The ultrasonic generator overhead is arranged on the internal face of drum, and its bottom is higher than vapour
The upper limit of bag safety levels, ultrasonic generator are connected by wire with the high frequency electric source of outside.
Preferably, the multiple ultrasonic generator overhead is in the liquid level gauge of the middle part of drum internal face and both ends
Near.
In above-mentioned technical proposal of the present utility model, the ultrasonic generator is using frequency in 20~30kHz scopes
Interior ultrasonic generator.
Boiler described in the utility model uses fluidized-bed combustion boiler, coal-powder boiler, grate furnace, gas fired-boiler or oil burning boiler.
The utility model has the technique effect of advantages below and high-lighting：1. the utility model is installed super at the top of drum
Sound wave generating device, ultrasonic generator is opened when operation exception, fluid molecule is drastically moved using sound wave, in addition sound
The effect of pressure, accelerate the rupture of foam on carbonated drink interface, the harm brought when triggering accident because of priming can be substantially reduced；
2. the utility model with adjustment burning, open blowdown and use defoaming net etc. compared with means, effect is more rapid, efficiently and can
Lean on, the softened water of more high salinity can be used under conditions of safe operation is ensured, reduces disposing polluted water in oil cost；3. can
Enough fully achieve Electronic control, can control on demand ultrasonic intensity, capacity usage ratio is high；4. the utility model is simple in construction, easy
In implementation, can be used with newly-built or old boiler matching, boiler can be fluidized-bed combustion boiler, coal-powder boiler, grate furnace, combustion
Gas boiler or oil burning boiler.
Brief description of the drawings
Fig. 1 is a kind of boiler-steam dome principle schematic diagram with ultrasonic wave defoaming device of the present utility model.
In figure：1- drums；2- liquid level gauges；3- feed pipes；4- vertical downcomer tubes；5- evaporating heating surfaces；6- blow-off pipes；7- vapour
Water separation device；8- steam fairleads；9- ultrasonic generators；10- wires.
Embodiment
Principle, concrete structure and preferred forms of the present utility model are further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural principle of the boiler-steam dome embodiment with ultrasonic wave defoaming device provided by the utility model
Schematic diagram, the device include drum 1, liquid level gauge 2, evaporating heating surface 5, water separator 7 and ultrasonic generator 9；Institute
State drum 1 and be provided with feed pipe 3, vertical downcomer tube 4, blow-off pipe 6 and steam fairlead 8；The top of ultrasonic generator 9 is consolidated
Dingan County can install one or more on drum internal face, and ultrasonic generator passes through wire and outside high-frequency electrical
Source is connected.
Ultrasonic generator is arranged on the medium position of drum and liquid level gauge preferably (the present embodiment installation nearby at both ends
3 ultrasonic wave defoaming devices), its bottom should be higher than that the upper limit of drum safety levels.Experimental study shows that the ultrasonic wave is sent out
The frequency that generating apparatus 9 is sent should in the range of 20~30kHz, for fluidized-bed combustion boiler, coal-powder boiler, grate furnace, gas fired-boiler or
The drum of oil burning boiler can be used.
Mechanism and the course of work of the present utility model are as follows：
High salinity softened water is introduced in drum after economizer preheats by feed pipe, by the allocated header of vertical downcomer tube
Into evaporating heating surface.It is changed into low mass dryness fraction steam water interface after boiler water is heated, passes back into water separator, through carbonated drink point
Steam from after draws drum from by steam fairlead, and the feedwater isolated is passed back into drum.In drum be provided with one or
Multiple liquid level gauges, effectively to monitor the liquid level of boiler-steam dome.In running, with the continuous evaporation of saturated vapor, stove water is not
It is disconnected to be concentrated, easily cause the concentration of the material of water surface foaming also to increase therewith in pot water, when the concentration for the material for causing foaming
When higher, froth bed will be produced on carbonated drink interface, priming phenomenon occurs, causes carbonated drink boundary to be difficult to distinguish, liquid level gauge
Interior waterline rapid fluctuation, steam water-level can not be correctly monitored, and largely band water, the highly effective and safe operation to equipment cause steam
Harm.Ultrasonic generator is now opened, and controls intensity of acoustic wave, sends the ultrasonic wave of 20~30kHz frequencies.Sound wave is rapid
Froth bed is acted on, accelerates the motion of froth bed fluid molecule, while produces the effect of acoustic pressure, so as to eliminate on carbonated drink interface
Foam, makes equipment normal operation, then takes adjustment burning, opens the modes such as blowdown thoroughly to eliminate priming phenomenon.Need
It is noted that ultrasonic generator quantity and frequency and intensity of acoustic wave be design parameter with boiler and its system and
The change of the operating condition of boiler and change.
