Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of higher-pressure deaerator noise-reduction energy-saving device, including oxygen discharging tube 1 and
Dilatation storehouse 2, the closed at one end of oxygen discharging tube 1, the other end are open, and the open end of oxygen discharging tube 1 is to the row with higher-pressure deaerator 3
Oxygen door 31 is connected, the closed end sealing insertion dilatation storehouse 2 of oxygen discharging tube 1, in the oxygen discharging tube pipeline section 11 being located inside dilatation storehouse 2
It is provided with several through-holes 4 on side wall, the top in dilatation storehouse 2 is provided with exhaust outlet, is communicated with exhaust pipe 5 in exhaust ports；?
In the present embodiment, the bottom in dilatation storehouse 2 is provided with drain port, drain port is connected to by the hydrophobic reuse pipe 7 with drain valve 6 and is dredged
Water tank 8 can preferably recycle the demineralized water being entrained with when deoxygenation door 31 is vented in this way；In the present embodiment, dilatation storehouse 2
Bottom plate be obliquely installed to drain port to lower in four sides, can preferably recycle the condensation demineralized water in dilatation storehouse 2 in this way；At this
In embodiment, dilatation storehouse 2 is inserted into the closed end of exhaust pipe 1 from bottom to top, and the closed end of exhaust pipe 1 is away between 2 top of dilatation storehouse
Distance H be dilatation storehouse height M 1/4, can preferably discharge in this way from the through-hole 4 of exhaust pipe 1 be discharged gas pressure,
Make gas pressure release more evenly, and then reduces exhaust noise；In the present embodiment, disappear what the exit of exhaust pipe 5 was connected to
