Embodiment
With reference to accompanying drawing, a kind of tower top demister handled for sulfuric acid tail gas, by demisting silk screen 1, baffling demister 2,
Hollow ball packing layer 3 and cyclone 4 are constituted.Demisting silk screen 1, baffling demister 2, hollow ball packing layer 3 and cyclone 4 are from up to
Under be laid in the top of tower body 5 successively, undermost cyclone 4 is located at the top of the inside the superiors shower nozzle 6 of tower body 5.
The thickness of above-mentioned demisting silk screen 1 is 100-120mm, and the thickness of hollow ball packing layer 3 is 150-200mm, demisting silk
The distance between net 1 and baffling demister 2 are 300-500mm, and the distance between baffling demister 2 and hollow ball packing layer 3 are
The distance between 200-300mm, hollow ball packing layer 3 and cyclone 4 are 200-300mm.Following specific setting can such as be carried out：Remove
The thickness of mist silk screen 1 is 120mm, and the thickness of hollow ball packing layer 3 is 200mm, between demisting silk screen 1 and baffling demister 2
Distance is 300mm, and the distance between baffling demister 2 and hollow ball packing layer 3 are 300mm, hollow ball packing layer 3 and cyclone
The distance between 4 be 300mm.
Above-mentioned baffling demister 2 includes the corrugated sheet 201 of multiple parallel layings, is provided with the bending place of corrugated sheet 201
Fin 202, folding line direction of the fin 202 along corrugated sheet 201 is laid, and the section of fin 202 is curved.The multiple ripple
The top and bottom of shape plate 201 laterally wear two connecting rods 203.The cyclone 4 includes multiple swirl vanes 401, institute
The one end for stating swirl vane 401 is fixed on centre frame 402, and the other end is fixed on outer shroud 403.The swirl vane 401 is in
Vertical, the width of swirl vane 401 is become narrow gradually by one end of connection outer shroud 403 to the one end for connecting centre frame 402, i.e.,
The top bottom both sides of swirl vane 401 are in slope design.
It is equipped with rinsing water system on above-mentioned baffling demister 2 and cyclone 4, further can effectively prevents baffling demister
2 and cyclone 4 on fouling and clogging.
The utility model demister uses 4 groups of demisting silk screen 1, baffling demister 2, hollow ball packing layer 3 and cyclone
The mode of conjunction, and to the distance between demisting silk screen 1 and the thickness of hollow ball packing layer 3, each demisting layer, and baffling demister
2 and the structure etc. of cyclone 4 specifically designed, imitated for the mist and dust separation carried secretly after sulfuric acid tail gas spray process
Rate is high, and resistance is small, and big with allowable superficial gas velocity, is difficult obstruction, and erection space is small, and economical operation is safe and reliable, operation side
Just the advantages of.
The course of work of the present utility model is briefly described below：
Sulfuric acid tail gas with the spray liquid that shower nozzle 6 sprays after contacting, and the partial contamination material in sulfuric acid tail gas is by spray liquid
Washing is removed.Sulfuric acid tail gas entrainment and dust after being washed through spray liquid continue up operation, sequentially pass through cyclone 4,
Hollow ball packing layer 3, baffling demister 2 and demisting silk screen 1.In cyclone 4, swirl vane 401 is first by the larger mist of particle diameter
Foam, which is separated, to be removed, and then operation carries out further mist removal into hollow ball packing layer 3.After being handled through hollow ball packing layer 3,
The larger mist of some particle diameters is substantially achieved thorough removal, and the gas then containing the smaller mist of particle diameter and dust is with certain speed
Baffling demister is flowed through, because the inertial impaction of gas is acted on, mist collides with corrugated sheet 201 and is attached to corrugated sheet table
On face.The diffusion of mist, the gravitational settling of mist make mist form larger drop and be transported forward with air-flow in waveform plate surface
Move to corrugated sheet turning, the surface due to steering centrifugal force and its with the rubbing action, suction-operated and liquid of corrugated sheet 201
Tension force causes drop increasing, until the drop gathered arrives greatly climbing power and liquid of the gravity more than gas of its own generation
When making a concerted effort of surface tension, drop just is separated from waveform plate surface.Simultaneously as the setting of fin 202, it is most compared with
Small drop is also blocked aggregation, then separates.The structures that are folded to of corrugated sheet 201 add the machine that mist is captured more
Meeting, the tiny mist not being removed is acted at next turning and is captured by identical.Through baffling demister 2 repeatedly
Effect, some tiny mists and dust can also be removed substantially, and remainder flows through demisting silk screen 1 with gas again, through demisting
After the processing of silk screen 1, tiny mist and dust are thoroughly removed.The utility model is arranged using said structure, is substantially increased
Demisting efficiency.
Above-mentioned tower top demister can also be used for the processing of hydrochloric acid tail gas.
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.
