Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
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
Sound cylinder 9 is provided with several noise reduction gas vents 10 on the side wall of hush pipe 9, in this way can be to after the buffering decompression of dilatation storehouse
Gas carries out secondary noise reduction, further reduced exhaust noise；
When installation, the closed end of oxygen discharging tube 1 need to be only connected to each other with the exhaust valve 31 of higher-pressure deaerator 3 and be connected to；In high pressure
In 3 course of work of oxygen-eliminating device, the gas being discharged from oxygen discharging door 31 can be introduced into oxygen discharging tube 1, then through each through-hole 4 on oxygen discharging tube 1
Dilatation storehouse 2 is sprayed into, the gas in oxygen discharging tube 1 is behind the penetrating of through-hole 4 dilatation storehouse 2, on the one hand, the discharge pressure of gas is through dilatation storehouse
Reduction can be released after 2 bufferings and the speed of gas can also reduce, and then reduces discharge noise indirectly, reach a noise reduction
Purpose, on the other hand, from through-hole 4 spray into dilatation storehouse 2 gas can be in contact with the side wall in dilatation storehouse 2, gas with dilatation
When the side wall in storehouse 2 is in contact, the desalination water vapour carried secretly in gas can be condensed into condensation demineralized water and be stored in dilatation storehouse 2,
When the condensation demineralized water in dilatation storehouse 2 reaches a certain amount of, drain valve 6 is opened, the condensation demineralized water in dilatation storehouse 2 can be through at this time
Drain port, drain valve 6 and hydrophobic reuse pipe 7 flow to store in drain tank 8 and recycle；
Enter hush pipe through exhaust pipe 5 again through the gas that dilatation storehouse 2 buffers decompression and has been recovered the desalination water vapour being entrained with
9, then be discharged from each noise reduction gas vent 10 of hush pipe 9, gas can be by two when being discharged by hush pipe 9 and each noise reduction gas vent 10
Secondary noise reduction, gas exhaust noise final after a noise reduction and secondary noise reduction only have 50 decibels.
The invention has the advantages that exhaust noise can be effectively reduced in (1), exhaust noise can be reduced to 50 points from 80 decibels
Shellfish alleviates noise pollution；(2) 2 tons of desalinations can be recycled in the demineralized water that oxygen discharging door gives off when can recycle load fluctuation every time
Water greatly reduces the loss of demineralized water.
