Description
Technical field
The present invention relates to technical field of environment protection equipment, and in particular to a kind of efficient desulfurizing tower.
Background technique
Desulfurizing tower is the equipment for carrying out desulfurization process to industrial waste gas, is the important equipment in chemical industry equipment, desulfurizing tower is
A kind of desulfuration efficiency is high, the desulphurization plant of the lower simultaneous energy dedusting of the pressure loss.
Desulfurizing tower passes through the improvement of many years, has evolved into spraying type, Venturi type, eddy flow template, eddy flow column type, floating ball
Various types of desulfurizing towers, the equipment and technologies such as type, sieve plate type, Pneumatic emulsifying type reach its maturity.
The desulfurizing tower of spraying type is one of the most widely used desulfurizing tower type, using akaline liquid as carrier, by cigarette
The harmful substances such as dirt, sulfur dioxide, hydrocarbon in gas separating treatment from flue gas absorbs sedimentation, finally reaches purification
The purpose of flue gas.Spraying type desulfurizing tower has structure simple, and the reliable advantage of technical maturity is widely used in large power plant, in
Small-sized low-sulfur smoke gas treatment；For high-sulfur smoke gas treatment, coloured industry is based on Pneumatic emulsifying desulfurizing tower, Multi-layer sprinkling tower etc..
Wherein, desulfurizing tower generates a large amount of droplets at runtime, goes back dust-laden particle in a large amount of water mists, influences in tower just
Often operation.Demisting dust-extraction unit in the prior art mostly uses Open architecture, in use, the setting spray of demisting dust-extraction unit top
Water drenching, shower water, which flows downward, influences defogging effect.
Gas flows up in desulfurizing tower, eventually arrives at the discharge of tower top position.For meet the requirement of environmental protection, needing will be in gas
Solid particle or other magazines removal after, purification discharge.
In the prior art, baffle plate is mostly used to carry out gas purification, demisting, baffle plate purifying rate is low, and structure is complicated,
Installation maintenance is inconvenient.
In addition, the liquid in desulfurizing tower after spray can gather together, collection device is flow to by circulating line, was sprayed
Contain particles and other solid impurities such as a large amount of calcium carbonate, magnesium sulfate, calcium sulfate, recycle slurry liquid stream in loop slurry afterwards
In dynamic process, above-mentioned particle and solid impurity can cause to scratch to pipeline inside, pipeline life be reduced, in addition, loop slurry
In also contain a certain amount of sour gas, can be to pipeline by certain corrosiveness.Prior art majority using pipe lining modeling,
The mode of lining rubber protects pipeline, but effect is not significant, and pipeline life is lower, increases using and safeguarding for desulfurizing tower
Cost.
There are some sour gas inside desulfurizing tower, have the function of corrosion to the facility in spray column, reduce desulfurizing tower
The service life of interior facility.Wherein, spray liquid pipeline is the equipment that setting is more in desulfurizing tower, and pipeline outer wall is easy by acid
The corrosion of property substance.Liquid in spray liquid pipeline is circulating liquid, wherein there may be some solid impurity particles, liquid flow
When dynamic, inner wall of the pipe can be caused to scratch, to influence the service life of pipeline.
The tower body of desulfurizing tower mostly uses glass flake, and the glass flake time has grown the phenomenon that being easy to happen cracking, falling off, right
The use of desulfurizing tower generates adverse effect.In addition, there may be some solid impurity particles inside desulfurizing tower, when liquid flows,
Desulfurizing tower tower body inner wall can be caused to scratch, to influence its service life.

Corrosiveness of the sour gas external, in desulfurizing tower to pipeline；Structure sheaf is the main support structure of spray liquid pipeline；Second
Erosion resistant coating can prevent the acidic materials inside spray liquid pipeline to the corrosiveness of spray liquid pipeline；Wearing layer can prevent solid miscellaneous
Scratch of the matter particle to spray liquid pipeline.
First erosion resistant coating and the second erosion resistant coating are FRP material, and wearing layer is silicon carbide material, and structure sheaf is stainless
Steel material.
The spray liquid pipeline is supported by bracket, and spray liquid pipeline connects spray head, and spray head setting is in bracket lower part, spray
The liquid that leaching head sprays avoids bracket, slows down the corrosion to bracket.
Priming coat, intermediate course, wearing layer are successively arranged on the inside of the tower wall of the tower body, intermediate course uses compound glass
Fiber woven roving covers suitable glass flake plasticine on priming coat.
The wearing layer uses silicon carbide or corundum, and the intermediate course will be appropriate using 4-5 layers of glass fibre woven roving
Glass flake plasticine cover on priming coat, the glass flake plasticine of the intermediate course includes vinylite, glass squama
Piece.
It advantages of the present invention and has the beneficial effect that
The configuration of the present invention is simple, water mist removal rate are high.When operation test, water mist is formed using the water of 19.72KG, is sent into wind
Speed is 14 meter per seconds, and after the processing of the utility model demisting deduster, the utility model collects the water of 14.474KG, that is, is gone
The water of 14.474KG in desulfurizing tower is removed, removal rate reaches 73.4%；Under above-mentioned condition, when feeding wind speed is set as 8 meter per second,
Water mist removal rate is greater than 80%.It can be seen that the working efficiency of desulfurizing tower can be improved in the utility model, and in the work of demisting
In, play the role of dedusting.
