The pump orifice of water jet air ejector is connect, the contraction section of the water jet air ejector protrudes into cooling water tank, and the water jet air ejector top connects
Connect the outlet of water-jet pump.
Further, if being equipped with dry gas iron reduction layer in the reduction apparatus.
Further, the cooling water tank is equipped with water inlet.
It further, is vacuum structure in the degasifier.
Further, pass through the pump orifice of flanged joint water jet air ejector at the top of the degasifier.
Further, the oxygen separator, gas reduction device and degasifier are all made of pipeline connection.
The utility model has the following beneficial effects:
The utility model and other Deaerator Structures are there are different, by oxygen separator and gas reduction apparatus by oxygen
Realization deoxygenation is separated, the water after deoxygenation is sent into boiler by degasifier vacuum structure, and degasifier connects water jet air ejector, leads to
It crosses jetting to vacuumize, the water oxygen content being transported in boiler is low, and then guarantees the work of high efficiency boiler rate.
The utility model structure is simple, and compared with other oxygen-eliminating devices, oxygen removal efficiency is high, each equipment can be decomposed and be dismantled
And installation, it is easy maintenance.
Detailed description of the invention
Fig. 1 is the utility model structure chart.
1, oxygen-eliminating device water inlet, 2, heater, 3, oxygen separator, 4, gas reduction device, 5, degasifier, 6, jetting pumping
Gas device, 7, oxygen-eliminating device water outlet, 8, cooling water tank, 9, water-jet pump, 10, gas iron reduction layer.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, degassing formula oxygen-eliminating device, which is characterized in that oxygen-eliminating device includes oxygen separator 3, and oxygen separator 3 is set
There is oxygen-eliminating device water inlet 1,1 end of oxygen-eliminating device water inlet is equipped with heater 2, the outlet of the oxygen separator 3 connection gas reduction dress
4 import is set, the import of the outlet of the gas reduction device 4 connection degasifier 5,5 bottom of degasifier goes out equipped with oxygen-eliminating device
The mouth of a river 7,6 pump orifice of water jet air ejector is connected at the top of the degasifier 5, and the contraction section of the water jet air ejector 6 protrudes into cooling water
Case 8, the outlet of 6 top of the water jet air ejector connection water-jet pump 9.
If being equipped with dry gas iron reduction layer 10 in the reduction apparatus 4.
The cooling water tank 8 is equipped with water inlet.
It is vacuum structure in the degasifier 5.
Pass through the pump orifice of flanged joint water jet air ejector 6 at the top of the degasifier 5.
The oxygen separator 3, gas reduction device 4 and degasifier 5 are all made of pipeline connection.
Embodiment:
Concrete operating principle squeezes into unboiled water by oxygen-eliminating device water inlet 1, under the heating running of heater 2, by oxygen
It is separated from unboiled water, unboiled water is further being isolated into oxygen in oxygen separator 3, the water after then separating enters
Gas reduction device 4, gas reduction device 4 is interior to be equipped with gas iron reduction layer 10, and oxygen and iron filings are restored, and three oxygen are generated
Change two iron.Enter in degasifier 5 there are also a small amount of gas and liquid, degasifier 5 is high vacuum state, the working principle of degasifier
It is using Henry's law and Dalton's law, according to Henry's law it is found that in closed container, any gas is existed simultaneously in water
On face, then the solubility of gas and the partial pressure of their own are directly proportional, and the partial pressure of the solubility of gas only with itself
It is related.Under a certain pressure, as water temperature increases, the partial pressure of water vapour increases, and the partial pressure of air and oxygen is increasingly
It is small.At 100 DEG C, the partial pressure of oxygen is reduced to zero, and the dissolved oxygen in water is also reduced to zero.When pressure is less than atmosphere on the water surface
When pressure, the solubility of oxygen also can reach zero in lower water temperature.In this way, space oxygen molecule is by water jet air ejector on the water surface
Extraction is discharged in cooling water tank, or is transformed into other gases, so that water oxygen just constantly overflows when the partial pressure of oxygen is zero
Out, water jet air ejector 6 carries out pumping by water-jet pump 9 and is discharged to cooling water tank, so that cooling water jet stream in water jet air ejector 6,
Realization vacuumizes, and under vacuum conditions, so that gas and liquid are kept completely separate, and then liquid is discharged simultaneously from oxygen-eliminating device water outlet 7
It is transported in boiler.
