The utility model comprises a sealing tank, a water inlet valve, a water outlet pump, a sewage outlet valve, a check valve and a vacuum instrument, wherein the water inlet valve is arranged at the upper part of the sealing tank, so that the sealing tank is connected with a water inlet pipe. The water outlet pump is arranged at the lower part of the sealing tank, so that the sealing tank is connected with a water outlet pipe. The sewage outlet valve is arranged at the lower part of the sealing tank. The check valve and the vacuum instrument are respectively arranged at the upper part of the sealing tank. When a system works in a stable state, the vacuum oxygen remover can keep the oxygen meltage of the boiler water below 0.1 mg/ L to effectively ensure that the oxygen content of the boiler water obtains the national standard.
Description
Technical field
The utility model relates to a kind of 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 the main cause of heat power equipment corrosion, and it can cause the oxygen corrosion between run duration and lay-off period of boiler and relevant device such as radiator.For preventing and alleviate the oxygen corrosion of therrmodynamic system run duration, must carry out deoxygenation to boiler feedwater.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 steam pressure is 1.6～2.5Mpa, hot-water boiler rated power 〉=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 steam to spray and water gunite acquisition vacuum, but the equipment volume of these methods is big, and deaerating effect is poor when being used for normal temperature.Adopt the part water of the hermetically sealed can of the water filling extraction jar outer jar interior vacuum that obtains, surplus water or the new water that injects boiling point under vacuum condition reduce in jar, water reaches boiling point at normal temperatures, oxygen is overflowed from water, thereby reach the order ground of deoxygenation, but existing device has adopted magnetic valve and gas-water separation valve, exhaust control more complicated when the control exhaust.
Summary of the invention
The purpose of this utility model is the vacuum deaerating plant that proposes a kind of boiler feed water, changes the structure of prior art, to reduce the quantity of part of appliance, increases operational reliability, and device systems is simplified.
The vacuum deaerating plant of the boiler feed water that the utility model proposes comprises hermetically sealed can, water inlet valve, delivery port water pump, sewage draining exit valve, check-valves and vacuum instrumentation.Water inlet valve places hermetically sealed can top, and hermetically sealed can is connected with inlet channel.The delivery port water pump places the hermetically sealed can bottom, and hermetically sealed can is connected with the delivery port pipeline.The sewage draining exit valve places the hermetically sealed can bottom.Check-valves and vacuum instrumentation place hermetically sealed can top respectively.
The vacuum deaerating plant of the boiler feed water that the utility model proposes, utilize approaching zero the characteristics of water Gas Solubility when fluidized state, extract water outward out with water pump and make jar interior vacuum that forms, water filling in jar again, utilize water level to rise and make the residual gas volume compression, the pressure of gas increases, the check-valves 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 atmospheric pressure in the pipe, in jar, this check-valves 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.Reach the purpose of boiler feed water deoxidation.When system works in stable state following time, this vacuum deaerating plant 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 content is up to state standards.
Description of drawings
Fig. 1 is the vacuum deaerating plant structural representation of the boiler feed water of the utility model design.
Among Fig. 1, the 1st, hermetically sealed can, the 2nd, delivery port water pump, the 3rd, sewage draining exit valve, the 4th, water inlet valve, the 5th, vacuum instrumentation, the 6th, check-valves, the 7th, outlet conduit, the 8th, inlet channel.
The specific embodiment
The vacuum deaerating plant of the boiler feed water that the utility model proposes, its structure comprise hermetically sealed can 1, water inlet valve 4, delivery port water pump 2, sewage draining exit valve 3, check-valves 6 and vacuum instrumentation 5 as shown in Figure 1.Water inlet valve 4 places the top of hermetically sealed can 1, and hermetically sealed can 1 is connected with inlet channel 8.Delivery port water pump 2 places the bottom of hermetically sealed can 1, and hermetically sealed can 1 is connected with delivery port pipeline 7.Sewage draining exit valve 3 places the bottom of hermetically sealed can 1.Check-valves 6 and vacuum instrumentation 5 place the top of hermetically sealed can 1 respectively.
Below in conjunction with accompanying drawing, introduce the operation principle and the process of the vacuum deaerating plant that the utility model proposes in detail: hermetically sealed can 1 is the tank body of the born pressure of steel, tank body links to each other with inlet pipeline 8 by water inlet valve 4, offer system by delivery port water pump 2 water with deoxidation, vacuum instrumentation 5 is connected to the top of tank body 1 in order to monitoring jar interior vacuum by pipeline, check-valves 6 one ends of band gas-water separation function are connected to hermetically sealed can 1 top, and the other end leads to atmosphere.The bottom of hermetically sealed can 1 is provided with sewage draining exit valve 3, and valve 3 can discharge the impurity that is deposited in hermetically 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.
Boiler feed water enters the hermetically sealed can 1 of this device by water inlet valve 4.Because the work of delivery port water pump 2 makes and forms vacuum in the hermetically sealed can.Because the boiling point of water is relevant with pressure, the water in the hermetically sealed can is in fluidized state at normal temperatures, makes that dissolved gases parses from water in the water.When water temperature one regularly, hermetically sealed can internal pressure low more (being that vacuum is high more), then residual gas content is just few more in the water.The gas of separating out from water flows out hermetically sealed can by the check-valves 6 of band gas-water separation function, and the deaerated water that takes off peroxide flows out to boiler water supply by delivery port water pump 2.By the check-valves outflow hermetically sealed can of the gas that removes in the water, to airborne release by band gas-water separation function.Vacuum instrumentation monitoring state.The unlatching and the closure of each valve cooperatively interact, periodic water filling, and the deoxygenation function of vacuum water is finished in exhaust.
