Abstract
The utility model discloses a kind of wire mesh demisters that foam removal effect is good, including cylindrical lateral wall, vapour-liquid filter screen is equipped in the side wall, the bottom of the vapour-liquid filter screen is equipped with lower pallet, Under The Grille is equipped between lower pallet and vapour-liquid filter screen, the top of the vapour-liquid filter screen is equipped with overhead gage, and upper grid is equipped between overhead gage and vapour-liquid filter screen, and the side wall positioned at vapour-liquid filter screen lower edge is equipped with obliquely at least provided with a through-hole.The side wall that through-hole is set to vapour-liquid filter screen lower edge can make the drop after condensation flow out from the through-hole of side wall under the blowing of steam, and the through-hole being arranged obliquely effectively can carry out acceleration downslide using the gravity of drop itself.
Description
Technical field
The utility model relates to sulfuric acid vapor generator fields, and in particular to a kind of wire mesh demister that foam removal effect is good.
Background technique
Wire mesh demister is a kind of gas-liquid separation device, and gas passes through the silk pad of demister, can remove the mist of deentrainment.When
When gas with mist rises through silk screen with certain speed, due to the effect of inertia that mist rises, mist and wire mesh filaments
It collides and is attached in filament surfaces.The diffusion of mist in filament surfaces, mist gravitational settling, form mist larger
Drop the interface points of two silks is flow to along filament.The capillary of the wettability of filament, the surface tension of liquid and filament
Effect, so that drop is increasing, until the drop of aggregation arrives greatly climbing power and liquid of the gravity more than gas of its own generation
When the resultant force of body surface tension, drop is just separated from filament and is fallen.Wire mesh demister used at present only has lower pallet
Steam inlet is plane at one, causes steam and vapour-liquid filter screen contact area is smaller, the drop falling direction of condensation for
Under, be also difficult to fall in the case where being jacked up upwards by steam, while drop jacked up by steam after toward two side slips, cause drop
The case where more being piled up in side-walls, demister be easy to cause to block.
Summary of the invention
The utility model overcomes existing defect to provide a kind of wire mesh demister that foam removal effect is good, and foam removal effect is good.
The utility model is realized using following scheme:
A kind of wire mesh demister that foam removal effect is good, including cylindrical lateral wall, the side wall is interior to be equipped with vapour-liquid filter screen, institute
The bottom for stating vapour-liquid filter screen is equipped with lower pallet, and Under The Grille, the vapour-liquid filter screen are equipped between lower pallet and vapour-liquid filter screen
Top be equipped with overhead gage, between overhead gage and vapour-liquid filter screen be equipped with upper grid, positioned at the side wall of vapour-liquid filter screen lower edge
Equipped with obliquely at least provided with a through-hole.After the side wall that through-hole is set to vapour-liquid filter screen lower edge can make condensation
Drop is flowed out from the through-hole of side wall under the blowing of steam, the through-hole being arranged obliquely, can effectively utilize drop itself
Gravity carry out acceleration downslide.
The further improvement project of the utility model is, the lower pallet and Under The Grille by middle part towards edge gradually under
Drop filters net side protrusion towards vapour-liquid.Lower pallet and Under The Grille, which are gradually declined by middle part towards edge towards vapour-liquid, filters net side
The bottom concave surface convexed to form increases the contact area of steam Yu vapour-liquid filter screen, so that steam filtration efficiency gets a promotion,
It is easier to the drop of condensation from the through-hole outflow on side wall.
The further improvement project of the utility model is that vapour-liquid filter screen lower surface is bonded company with Under The Grille upper surface
It connects.To guarantee that the steam with mist can large area be effective is contacted with vapour-liquid filter screen.
The further improvement project of the utility model is that the through-hole is along side wall circumference uniform distribution.Guarantee in wire mesh demister
Drop can uniformly and effectively fall.
Compared to the prior art the utility model has the advantage that
Original lower pallet and Under The Grille are gradually declined section towards edge towards strainer side by middle part by the utility model
Protrusion improves filter efficiency so that the contact area of steam and vapour-liquid filter screen is increased, and it is convenient that through-hole is arranged on side wall
Drop is fallen, and avoiding the fixation position of lower pallet and side wall is not in ponding.
Detailed description of the invention
Fig. 1 is prior-art illustration.
Fig. 2 is the utility model cross section structure schematic diagram.
Specific embodiment
A kind of good wire mesh demister of foam removal effect as shown in Figure 1, 2, including cylindrical lateral wall 1 are set in the side wall
There is vapour-liquid filter screen 2, the bottom of the vapour-liquid filter screen 2 is equipped with lower pallet 3, is equipped with down between lower pallet 3 and vapour-liquid filter screen 2
The top of grid 4, the vapour-liquid filter screen 2 is equipped with overhead gage 5, and upper grid 6, institute are equipped between overhead gage 5 and vapour-liquid filter screen 2
It states lower pallet 3 and Under The Grille 4 is gradually declined towards edge by middle part, is raised towards 2 side of vapour-liquid filter screen.The bottom concave surface of formation
So that the gas that the same time is able to enter wire mesh demister increases, so that drop can be with rapid condensation.The vapour-liquid filter screen 2
Lower surface is fitted and connected with 4 upper surface of Under The Grille.It ensure that gas can be carried out effectively with vapour-liquid filter screen 2 to contact.It is described
Side wall 1 positioned at 2 lower edge of vapour-liquid filter screen is equipped with obliquely at least provided with a through-hole 7.Inclined hole can be quickly by vapour
The drop formed in liquid filter screen 2 is effectively arranged after 2 lower surface of vapour-liquid filter screen along arc is trickled to sidewall edge
Out.The through-hole 7 is along 1 circumference uniform distribution of side wall.The problem of ensure that drop can uniformly be discharged, not will cause hydrops.
