Description
Technical field
The utility model relates to a kind of ultrasonic vacuum deaerating plant of boiler feed water, belongs to the energy resource apparatus and technology field.
Background technology
Dissolved oxygen in the feedwater normally causes heat power equipment corrosive major cause, and it can cause the oxygen corrosion between run duration and lay-off period of boiler and relevant device such as scatterer.For preventing and alleviate the oxygen corrosion of therrmodynamic system run duration, must carry out deoxygenation to oiler feed.Regulation feedwater dissolved oxygen content≤0.1mg/L during national Specification boiler nominal steam pressure 1.6Mpa, dissolved oxygen content≤the 0.1mg/L of regulation feedwater when dissolved oxygen content≤0.05mg/L in regulation feedwater when vapor pressure is 1.6～2.5Mpa, hot water boiler rated output 〉=4.2Mw.Generally can adopt multiple mode deoxygenation, as: thermal de-aeration method, chemical deoxidizing, Deadsorbing and oxygen removing method, electrochemical deoxidization method and vacuum degassing process etc.Vacuum degassing process commonly used takes vapo(u)r blasting and jet of water method to obtain vacuum, but the equipment volume of these methods is big, and deaerating effect is poor when being used for normal temperature.Adopt the portion water of the sealed can of the water filling extraction jar outer jar interior vacuum that obtains, surplus water or the new water boiling point lowering under vacuum condition that injects in jar, water reaches boiling point at normal temperatures, oxygen is overflowed from water, thereby reach the order ground of deoxygenation, but the volume of deoxidation jar is little usually, and the water deoxygenation of finishing whole waterworks needs the long time.
Summary of the invention
The purpose of this utility model is the ultrasonic vacuum deaerating plant that proposes a kind of boiler feed water, changes the structure of prior art, the oxygen level of water in the speed of quickening deoxidation and the reduction system.
The ultrasonic vacuum deaerating plant of the boiler feed water that the utility model proposes comprises sealed can, water inlet valve, water outlet water pump, sewage draining exit valve, vacuum breaker and vacuum instrumentation, and ultrasonic transducer and ultrasonic power.Water inlet valve places sealed can top, and sealed can is connected with inlet channel.The water outlet water pump places the sealed can bottom, and sealed can is connected with the water outlet pipeline; Described sewage draining exit valve places the sealed can bottom.Vacuum breaker and vacuum instrumentation place sealed can top respectively.Ultrasonic transducer is fixed on the bottom of sealed can, and ultrasonic power links to each other with ultrasonic transducer.
The ultrasonic vacuum deaerating plant of the boiler feed water that the utility model proposes, utilize approaching zero the characteristics of water Gas Solubility when boiling state, propose a kind ofly to extract water outward out with water pump and form a vacuum in making jar, water filling utilizes water level to rise and makes the entrap bubble volume compression in jar again, the pressure of gas increases, the vacuum breaker that has the gas-water separation function of tank top is opened exhaust outside jar automatically when gas is compressed to its pressure greater than normal atmosphere in the pipe, in jar, this vacuum breaker cuts out again automatically during outer air pressure balance, water pump do not stop to the jar extracardiac pumping, simultaneously periodically in jar water filling form above-mentioned compression-exhaust process.In compression-exhaust process, in sealed can, launch ultrasonic wave by ultrasonic transducer, make the water in the sealed can be subjected to the ultrasonic continuous vibration, because the gas molecule that the compound action of negative pressure and certain temperature is dissolved in the water is overflowed rapidly from water, be gathered into a large amount of bubbles, at ultrasonic vibration and buoyancy float downward, accelerate degasification process. reach the purpose of boiler feed water deoxidation.When system works in steady state following time, the ultrasonic vacuum deaerating plant of this process can make the oxygen meltage of boiler feed water remain on below the 0.1mg/L, has guaranteed that effectively the boiler feed water oxygen level is up to state standards.

Among Fig. 1, the 1st, sealed can, the 2nd, water outlet water pump, 3 ultrasonic transducers, the 4th, ultrasonic power, the 5th, outlet conduit, the 6th, sewage draining exit valve, the 7th, water inlet pipe, the 8th, inlet channel and valve, the 9th, vacuum instrumentation, the 10th, vacuum breaker.
Embodiment
The ultrasonic vacuum deaerating plant of the boiler feed water that the utility model proposes, its structure comprise sealed can 1, water inlet valve 8, water outlet water pump 2, sewage draining exit valve 6, vacuum breaker 10 and vacuum instrumentation 9 as shown in Figure 1, ultrasonic power 4 and ultrasonic transducer 3.Water inlet valve 8 places the top of sealed can 1, and sealed can 1 is connected with inlet channel 7.Water outlet water pump 2 places the bottom of sealed can 1, and sealed can 1 is connected with water outlet pipeline 5.Sewage draining exit valve 6 places the bottom of sealed can 1.Vacuum breaker 10 and vacuum instrumentation 6 place the top of sealed can 1 respectively.Ultrasonic transducer 3 is fixed on the bottom of sealed can 1 and links by cable and ultrasonic power 4.
Below in conjunction with accompanying drawing, introduce the principle of work and the process of the ultrasonic vacuum deaerating plant that the utility model proposes in detail: sealed can 1 is the tank body of the born pressure of steel, tank body links to each other with suction culvert 7 by water inlet valve 8, offer system by water outlet water pump 2 water with deoxidation, vacuum instrumentation 9 arrives the top of tank body 1 in order to a monitoring jar interior vacuum tightness by pipe connection, vacuum breaker 10 1 ends of band gas-water separation function are connected to sealed can 1 top, and the other end leads to atmosphere.The bottom of sealed can 1 is provided with sewage draining exit valve 6, and valve 6 can discharge the impurity that is deposited in sealed can 1 bottom when opening.Each advances, and outlet and valve and tank body all have good sealing to guarantee the acquisition and the maintenance of vacuum tightness.Ultrasonic power 4 gives the ultrasonic transducer that is fixed on sealed can 1 bottom 3 power supplies by cable.
Boiler feed water enters the sealed can 1 of this device by water inlet valve 8.Because the work of water outlet water pump 2 makes and forms vacuum in the sealed can.Because the boiling point of water is relevant with pressure, the water in the sealed can is in boiling state at normal temperatures, makes that dissolved gases parses from water in the water.When water temperature one regularly, sealed can internal pressure low more (being that vacuum tightness is high more), then residual gas content is just few more in the water.The gas of separating out from water flows out sealed can by the vacuum breaker 10 of band gas-water separation function, and the deaerated water that takes off peroxide flows out through pipeline 5 to boiler water supply by water outlet water pump 2.By the vacuum breaker outflow sealed can of the gas that removes in the water, to airborne release by band gas-water separation function.Vacuum instrumentation monitoring state.In compression-exhaust process, in sealed can, launch ultrasonic wave by ultrasonic transducer, make the water in the sealed can be subjected to the ultrasonic continuous vibration, because the gas molecule that the compound action of negative pressure and certain temperature is dissolved in the water is overflowed rapidly from water, be gathered into a large amount of bubbles, at ultrasonic vibration and buoyancy float downward, accelerate degasification process.The unlatching and the closure of each valve cooperatively interact, periodic water filling, and ultrasonic deaeration in condenser function is finished in exhaust.
Ultrasonic transducer and power supply used in the ultrasonic vacuum deaerating plant of the present utility model adopt conventional products.
