Description
Technical field
The utility model relates to a kind of vertical gas-liquid fog separators for steam turbine, belong to gas-liquid demister field.
Background technique
One phase of Qinshan Phase II NPP 30Mw power generator turbine workshop is passing through the exhaust of condenser air ejector and oxygen-eliminating device exhaust process
In need to be through gas-liquid fog separator demisting, water removal, gas-liquid fog separator generally use silk screen demisting to separate, existing silk screen demisting
Separation service life is short, and gas-liquid fog separator defogging effect is general, directly affects detection effect and equipment operational safety.
Utility model content
The purpose of this utility model is to be to solve the problems, such as of the existing technology, provides a kind of long service life, demisting
The good vertical gas-liquid fog separator of effect.
The technical solution adopted in the utility model is as follows: a kind of vertical gas-liquid fog separator for steam turbine, including
Shell, mesh mist eliminator, air inlet, gas outlet and leakage fluid dram, the top of the shell are equipped with gas outlet, the downside peace of shell
Equipped with air inlet, the bottom end of shell is equipped with leakage fluid dram, and shell is equipped with twice mesh mist eliminator, and the mesh mist eliminator is mounted on
The top of air inlet, mesh mist eliminator include DP silk screen, grizzly bar, retaining ring, the support plate of tray type structure, the DP silk screen upper and lower two
Side is fixed by grizzly bar, and the retaining ring is fixed on the outside of upside grizzly bar, and the support plate is fixed on the outside of downside grizzly bar.
Furtherly, the air inlet operating pressure is 0.1MPa.
Furtherly, the mesh mist eliminator web material is 304 stainless steels.
Furtherly, the mesh mist eliminator net block thickness h is 150mm.
Furtherly, the nominal diameter of the mesh mist eliminator is 100mm.
The utility model compared with prior art possessed by advantage:
The utility model uses twice DP mesh mist eliminator, improves defogging effect；Silk screen separator uses 304 stainless steels
Material improves service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of mesh mist eliminator described in the utility model.
Fig. 3 is the structural schematic diagram of DP silk screen described in the utility model.
Appended drawing reference: shell 1, mesh mist eliminator 2, air inlet 3, leakage fluid dram 4, gas outlet 5, DP silk screen 6, grizzly bar 7, retaining ring
8, support plate 9, net block thickness h.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.
As shown in Figure 1, a kind of vertical gas-liquid fog separator for steam turbine, characterized in that including shell 1, silk screen
Demister 2, air inlet 3, leakage fluid dram 4 and gas outlet 5, the bottom end of the shell 1 are equipped with leakage fluid dram 4, the downside installation of shell 1
There is air inlet 3, the top of shell 1 is equipped with gas outlet 5, and shell 1 is equipped with twice mesh mist eliminator 2, and the mesh mist eliminator 2 is pacified
Mounted in the top of air inlet 3, the present embodiment carries out demisting to mixed vapour, not to the strict demand of the pressure loss, for as far as possible
Liquid particles in mixed vapour are filtered out completely, so mesh mist eliminator 2 selects the DP silk screen 6 of tray type structure, such as Fig. 2 institute
Show, about 6 two sides of DP silk screen are fixed by grizzly bar 7, and the retaining ring 8 is fixed on the outside of upside grizzly bar 7, the support plate 9
It is fixed on the outside of downside grizzly bar 7.As shown in figure 3, DP silk screen 6 is heavy duty detergent silk screen, flat filament or circle silk, DP type is can be used in twine
The porosity of silk screen is 0.9765, and defogging effect is good.
3 operating pressure of air inlet described in the present embodiment is set as 0.1MPa, works and improves for meeting gas-liquid demister and removes
Mist efficiency.
2 web material of mesh mist eliminator described in the present embodiment is 304 stainless steels, it has at low cost, high temperature resistant (tolerable
The high temperature of 1000-1200), the good advantage of rust resistance, while also having to aqueous slkali and most of organic acid and inorganic acid good
Good corrosion resistance, is particularly suitable for using under wet saturated steam environment.
As shown in Fig. 2, 2 net block thickness h of mesh mist eliminator is divided into 100mm and 150mm, because the present embodiment demisting require compared with
Height, so selecting net block thickness h for 150mm.
The nominal diameter of mesh mist eliminator 2 described in the present embodiment is 100mm, and nominal diameter is by existing formulaAnalysis gained is calculated, which is existing mature technology, and this will not be detailed here.
The working principle of gas-liquid fog separator: the gas with liquid particles is after the entrance of air inlet 3 with certain speed
Mesh mist eliminator 2 is risen through, due to the effect of inertia that mist rises, mist collides with 6 twine of DP silk screen and is attached to
On twine surface.The diffusion of mist on twine surface, mist gravitational settling, so that mist is formed biggish drop and along twine
It flow at the interface point of DP silk screen 6.The capillarity of the wettability of twine, the surface tension of liquid and twine, so that liquid
Drip it is increasing, when the drop of aggregation arrive greatly its own generation gravity be more than gas climbing power and surface tension of liquid conjunction
When power, drop will be detached from twine and fall to container bottom and flow out from leakage fluid dram 4, and gas passes through basic after mesh mist eliminator 2
Without mist, the gas after demisting is discharged from gas outlet 5.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
