Description
Technical field
The present invention relates to a kind of inside critical components of flue gas purifying equipment of field of environment protection, and in particular to a kind of electrostatic precipitation
The coating pole plate of device.
Background technology
With the deterioration increasingly of China's atmosphere quality, Environmental Protection in China situation it is increasingly serious, country increasingly pay attention to
The improvement of pollution and the improvement of environment, prevention and control of air pollution will be one of its main battle ground, and industrial flue gas cleaning is even more that its is heavy
Head play.
In recent years, electrostatic precipitator is applied more and more in industrial fumes purification, and efficiency of dust collection is also higher and higher.It is quiet
The operation principle of electric precipitator is so that flue gas is ionized using high voltage electric field, the dust in air-flow under electric field action it is charged with
Air-flow detaches.Cathode is made of the plain conductor of different section shape, is discharge electrode.Anode by different geometries metal
Plate is made, and is collecting electrode.Shadow of the performance of electrostatic precipitator by three factors such as dust characteristic, equipment construction and flue gas flow rates
It rings.
Electrostatic precipitator is divided into dry electrostatic cleaner and wet scrubber, and basic principle is all to lean on high-voltage corona discharge
Make dust charged, it is charged after dust dust collecting pole plate is reached under the action of electric field force, then pass through deashing device collecting plate
On dust.
Under normal circumstances, the pole plate material of dry electrostatic cleaner is usually ordinary carbon steel.After running a period of time, gather dust
Pole plate is often corroded by flue gas, and the surface of pole plate usually will appear corrosion pit, and meeting sprawling slowly expands in blocks, feelings
Condition is serious, or even will appear the phenomenon that pole plate is perforated.The pole plate material of wet cottrell is usually stainless steel, in humidity
In running environment, stainless steel polar plate also will receive the corrosion of flue gas.Once pole plate is corroded, both it has been unfavorable for the deashing of pole plate,
Also it is unfavorable for the charged of dust, greatly reduces electrostatic precipitator efficiency of dust collection.
In view of the above-mentioned problems, the technical program proposes a kind of coating pole plate of electrostatic precipitator.
Invention content
The present invention is easy to be caused deashing difficulty, the deduster of pole plate by flue gas corrosion for electrostatic precipitator dust collecting pole plate
A kind of the problems such as fluctuation of service, low efficiency of dust collection, it is proposed that coating pole plate of electrostatic precipitator.It is using in dust collecting pole plate
One layer of non-sticking lining of uniformly spraying, usually corrosion-resistant polymeric coating layer, covering cated pole plate can effectively prevent
Only corrosion and fouling, ensure the stable operation of electric field.
To achieve the goals above, present invention employs following technical solutions：
A kind of coating pole plate of electrostatic precipitator, it is made of pole plate and coating, it is characterised in that the two of dust collecting pole plate
Face equably sprays one layer of corrosion-resistant macromolecule non-sticking lining, which has acid/alkali-corrosion-resistant, good antiscale property, heat safe
Characteristic.
The coating pole plate has a characteristic of acid-alkali-corrosive-resisting, which has antiacid alkali resistant, anti-various has
The characteristic of solvent, polar board surface can effectively prevent pole plate to be corroded after covering this high molecular material, the thickness of polymeric coating layer
It is determined according to design requirement.
The coating pole plate have prevent from being collected dust fouling, easy-to-clean ash characteristic, which, which has, rubs
The extremely low feature of coefficient is wiped, it, can easily will be on pole plate by deashing device after the dust in flue gas is collected into polar board surface
Dust cleans up.
The coating pole plate is not only suitable for wet cottrell, while being also applied for dry electrostatic cleaner, pole plate
The high molecular material of surface covering has heat safe characteristic, and pole plate is made to can be suitably used for the higher dry type static dust of running temperature
Device.
The coating pole plate material is ordinary carbon steel, and thickness is determined according to design requirement.
Coating pole plate advantage of the electrostatic precipitator is：One, the characteristic of acid-alkali-corrosive-resisting.The macromolecule applies
The characteristic that layer has antiacid alkali resistant, resists various organic solvents, polar board surface can effectively prevent pole plate after covering this high molecular material
It is corroded.Two, dust fouling, easy-to-clean ash are prevented.The high molecular material has the characteristics that extremely low friction coefficient, the dust in flue gas
After being collected into polar board surface, the dust on pole plate can be cleaned up easily by deashing device.Three, applied widely.Pole plate
The high molecular material of surface covering has heat safe characteristic, so that the pole plate is not only suitable for wet cottrell, while also fitting
For dry electrostatic cleaner.Four, cost-effective.The coating pole plate is by the surface uniform fold corrosion resistant in ordinary carbon steel
Come what is realized, material cost, cost of manufacture are all relatively low for erosion, high temperature-resistant polymer material.Pole plate be not necessarily to continuous deashing, operation at
This is low.
The present invention will be further described with reference to the accompanying drawings of the specification.
Description of the drawings
Fig. 1 is the coating pole plate schematic diagram of electrostatic precipitator.
In figure：1, pole plate；2, coating.
Specific implementation mode
As shown in Figure 1, the coating pole plate of electrostatic precipitator is made of pole plate 1 and polymeric coating layer 2.Pole plate 1 passes through rolling
Or other modes shape, the thickness of pole plate is chosen according to operating condition design.Pole plate 1 after processing should remove surface rusty stain,
Greasy dirt, impurity etc. influence the factor that polymeric coating layer 2 adheres to.
One floor height molecular coatings 2 are uniformly covered by spraying or other modes on smooth, bright and clean 1 surface of pole plate.
The polymeric coating layer 2 has many characteristics, such as acid-alkali-corrosive-resisting, high temperature resistant, resists various organic solvents, friction coefficient low, which applies
2 optional polytetrafluoroethylene (PTFE) of layer, coating layer thickness are chosen according to operating condition design.
2 friction coefficient of polymeric coating layer of coating polar board surface is low, and pole plate not will produce scale formation, makes the coating pole plate
A variety of different purge modes are adapted to, and are not necessarily to continuous deashing, you can realize the stable operation of deduster.
