Direction inclination.
Organic solvent steam fog demister provided by the utility model, by labyrinth type except liquid layer and silk screen demisting layer are mutually tied
Conjunction mode, multi-level removes mist, improves the organic solvent rate of recovery.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model；
Fig. 2 is the movable silk screen demisting layer partial enlargement structural representation of the utility model；
Fig. 3 is the labyrinth type of the utility model except liquid layer partial enlargement structural representation.
Specific embodiment
The specific technical solution of the utility model is described with reference to the drawings.
As shown in Figure 1, organic solvent steam fog demister, including tower-like shell 1,1 bottom sides of shell are equipped with air inlet
1, top is equipped with gas outlet 5, and bottom is equipped with liquid outlet 6；1 interior bottom portion of shell is equipped with labyrinth type and removes liquid layer 3, labyrinth type
Except liquid layer 3 is located at air inlet 1, labyrinth type is except cavity is equipped with above liquid layer 3, the labyrinth type is except the cavity above liquid layer 3
Interior to be equipped with equal wind inclined plate 8, equal 8 lower end of wind inclined plate is tilted to air inlet direction.Equal wind inclined plate 8 can will be close to air inlet
1 biggish air-flow is obliquely upward far from the direction water conservancy diversion of air inlet 1, so that the air-flow for entering top is uniform.It is equipped with above cavity
Silk screen demisting layer, the silk screen demisting layer include two layers, the respectively activity of fixed the silk screen demisting layer 4 and lower layer on upper layer
Formula silk screen demisting layer 7, there are gap, the work between the fixed silk screen demisting layer 4 and movable silk screen demisting layer 7
The outer periphery of dynamic formula silk screen demisting layer 7 vibrates up and down formula along 1 inner wall of shell and moves；Fixed silk screen demisting layer 4 and gas outlet 5
Between there are gas converge cavity.
As shown in Fig. 2, 1 inner wall of shell is located in the up and down range of movable silk screen demisting layer 7 equipped with multiple
Vertical sliding slot 71, movable 7 outer periphery of silk screen demisting layer are connected with multiple sliding blocks 72, the sliding block 72 and sliding slot
71 form sliding pair, and 71 bottom of sliding slot is equipped with spring planet 74, and spring planet 74 and sliding block are connected between 72 bottom
Spring 73.The vibration of movable silk screen demisting layer 7 can use the impact vibration that gas flowing generates, can also be by vibration electricity
The liquid that luxuriant growth on movable silk screen demisting layer 7 gathers quickly is shaken by mode of vibration and is fallen by machine driving.
Due to movable silk screen demisting layer 7 vibrate up and down can not vertical up-or-down movement, the thus sliding block 72 and outer
There are gaps between 1 inner wall of shell, and exhaust gas passes through from gap in order to prevent, and sliding block 72 is provided on the outside opposite with shell 1
Corrosion-resistant sponge 75, the sponge 75 fill up the gap.
As shown in figure 3, the labyrinth type is except the frid 31 that liquid layer 3 includes that multiple cross sections are flute profile, the slot of frid 31
Mouthful facing away to air inlet 1, multiple about 31 frids are arranged successively one layer of composition and remove liquid plate, between adjacent frid 31 there are
Gap, multilayer are vertically arranged successively except liquid plate, and the adjacent gap removed on liquid plate mutually staggers, and there are skies for adjacent removing between liquid plate
Gap, except gap forms tortuous labyrinth type gas channel between gap and frid 31 between liquid plate.
Emission is summarized first, allows gas to lead into the spray column equipped with adjacent chlorine benzyl dichloride solution, by spray column
The coarse particles in exhaust gas afterwards are all filtered, and part organic solvent has been dissolved in adjacent chlorine benzyl dichloride.It is purified by scrubbing tower
Gas afterwards passes through the organic solvent steam fog demister again, recycles the partial organic substances in tail gas.When with mist gas with
When certain speed rising passes sequentially through labyrinth type except liquid layer 3, silk screen demisting layer, labyrinth type is used as coarse defogging device, silk screen except liquid layer 3
Demisting layer is as smart demister, and due to the effect of inertia that mist rises, mist is with labyrinth type except the frid 31 and silk screen of liquid layer 3 remove
The silk screen of mist layer collides and is attached on frid 31 and silk screen surface.The diffusion of mist, mist on frid 31 and silk screen surface
The gravitational settling of foam makes mist form biggish drop and collects along frid 31 and silk screen, until the drop of aggregation arrives greatly it certainly
Body generate gravity be more than gas climbing power and surface tension of liquid resultant force when, drop is just separated from frid 31 and silk screen
It falls.After gas passes through organic solvent steam fog demister, substantially free of mist.The mist in gas is separated, to improve operation
Condition optimizes technic index, reduces equipment corrosion, extends service life of equipment, increases treating capacity and the valuable material of recycling,
Environment is protected, atmosphere pollution etc. is reduced.Organic solvent steam fog demister reaches 98%- to partial size >=3 ~ 5um mist, arresting efficiency
99.8%, and gas passes through the pressure drop very little of organic solvent steam fog demister, only 250-500Pa is conducive to improve equipment
Production efficiency.As there is organic matter existing for solid-state form in exhaust gas, part solid-state organic solvent is easier to condense in organic
On solvent steam fog demister, generally use two sets organic solvent steam fog demisters, guarantee it is wherein a set of in use, it is another set of then
In purification, purification style selects hot nitrogen recoil, so that all organic solvents is liquefied, and collect into oil water separator.By
Organic solvent steam fog keeps organic exhaust gas dustless anhydrous all by detention after spray column and organic solvent steam fog demister；Into
High-specific surface area cellular activated carbon Adsorption Concentration device.
