From ability qualified discharge.And the mist particle diameter of mist or dust granules diameter very little, such as mechanicalness generation is 1.0~150
Between μm, and the mist particle diameter that coherency is produced is between 0.10~30 μm.
Typically demister is used in order to remove in the liquid phase of the mist in gas and entrainment, industrial production.Demister is one
Plant the essential device of widely used gas-liquid separation in industrial production and environmental protection industry.According to the purposes of demister or
Structure can be divided into numerous species, such as louver separator, gravitational settling type separator and whirlwind board separator, but these points
It is not high from device separative efficiency, and it is not readily separated the mist compared with small particle.Although mesh mist eliminator can separate general mist,
Phosphoric acid tail gas is handled but and not applied to, this is primarily due to that the solids such as ardealite can be produced when handling phosphoric acid tail gas,
It is easily caused silk screen blocking.Therefore, study and produce separative efficiency height, resistance drop is small, allowable superficial gas velocity is big, choke preventing function is strong
New and effective demister turn into industrial production in it is in the urgent need to address the problem of.
Utility model content
Based on above-mentioned technical problem, the utility model provides a kind of tower top demister handled for phosphoric acid tail gas.
The technical solution that the utility model is used is：
A kind of tower top demister handled for phosphoric acid tail gas, is made up of, baffling demisting baffling demister and cyclone
Device is arranged on the top of cyclone；The baffling demister includes the corrugated sheet of multiple parallel layings, in the bending place of corrugated sheet
It is provided with fin；The cyclone includes multiple swirl vanes, and one end of the swirl vane is fixed on centre frame, the other end

It is preferred that, the swirl vane is in vertical, during the width of swirl vane is extremely connected by one end of connection outer shroud
One end of heart frame becomes narrow gradually.
Advantageous effects of the present utility model are：
The utility model demister is by the way of baffling demister and cyclone combination, and to baffling demister and rotation
Structure of device etc. is flowed specifically to be designed, for the mist and dust separation efficiency high carried secretly after phosphoric acid tail gas spray process,
Resistance is small, while having allowable superficial gas velocity big, is difficult obstruction, erection space is small, and economical operation is safe and reliable, easy to operate
The advantages of.
Brief description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation that the utility model is arranged on inside absorption tower；
Fig. 2 is the principle schematic diagram of baffling demister in the utility model；
Fig. 3 is the principle schematic diagram of cyclone in the utility model.
Embodiment
With reference to accompanying drawing, a kind of tower top demister handled for phosphoric acid tail gas, by 2 groups of baffling demister 1 and cyclone
Be arranged on the top on absorption tower 3 into, baffling demister 1 and cyclone 2, and positioned at absorption tower 3 inside the superiors shower nozzle 4 it is upper
Side.Baffling demister 1 is located at the top of cyclone 2, and the distance between baffling demister 1 and cyclone 2 are 300-500 millimeters.
The baffling demister 1 includes the corrugated sheet 101 of multiple parallel layings, and the bending place of corrugated sheet 101 is provided with fin 102,
Folding line direction of the fin 102 along corrugated sheet 101 is laid, and the section of fin 102 is curved.The multiple corrugated sheet 101
Top and bottom laterally wear two connecting rods 103.The cyclone 2 includes multiple swirl vanes 201, the eddy flow leaf
One end of piece 201 is fixed on centre frame 202, and the other end is fixed on outer shroud 203.The swirl vane 201 is in vertical,
The width of swirl vane 201 is become narrow gradually by one end of connection outer shroud 203 to the one end for connecting centre frame 202, i.e. swirl vane
201 top bottom both sides are in slope design.
According to specific demisting dedusting needs, the baffling demister 1 can mounted on top arrangement it is multiple.
It is equipped with rinsing water system on above-mentioned baffling demister 1 and cyclone 2, further can effectively prevents baffling demister
1 and cyclone 2 on fouling and clogging.
The utility model demister is by the way of baffling demister 1 and cyclone 2 are combined, and to baffling demister 1
Specifically designed, imitated for the mist and dust separation carried secretly after phosphoric acid tail gas spray process with the structure of cyclone 2 etc.
Rate is high, and resistance is small, while having allowable superficial gas velocity big, is difficult obstruction, erection space is small, and economical operation is safe and reliable, operation
The advantages of facilitating.
The course of work of the present utility model is briefly described below：
Phosphoric acid tail gas with the spray liquid that shower nozzle 4 sprays after contacting, and the partial contamination material in phosphoric acid tail gas is by spray liquid
Washing is removed.Phosphoric acid tail gas entrainment and dust after being washed through spray liquid continue up operation, successively by the He of cyclone 2
Baffling demister 1.In cyclone 2, the larger mist of particle diameter is first separated and removed by swirl vane 201, while by gas lift
It is interval beneficial to the flow velocity of inertial separation, then run to baffling demister 1.When the gas containing mist with certain speed flows through folding
When flowing demister, because the inertial impaction of gas is acted on, mist collides with corrugated sheet 101 and is attached to waveform plate surface
On.The diffusion of mist, the gravitational settling of mist make mist form larger drop and be travelled forward with air-flow in waveform plate surface
To corrugated sheet turning, due to turning to centrifugal force and its being opened with the surface of the rubbing action, suction-operated and liquid of corrugated sheet 101
Power causes drop increasing, until the drop gathered arrives greatly climbing power and liquid table of the gravity more than gas of its own generation
When making a concerted effort of face tension force, drop just is separated from waveform plate surface.Simultaneously as the setting of fin 102, most smaller
Drop be also blocked aggregation, then separate.The structures that are folded to of corrugated sheet 101 add the chance that mist is captured more,
The mist not being removed is acted at next turning and is captured by identical, such repeated action, so as to greatly improve
Demisting efficiency.After gas is by baffling demister, mist is substantially thoroughly removed.
The relevant technology contents do not addressed in aforesaid way are taken or used for reference prior art and can be achieved.
It should be noted that under the teaching of this specification, any equivalent substitute side made by those skilled in the art
Formula, or obvious variant, all should be within protection domain of the present utility model.
