Description
Technical field
The utility model is related to technical field of electrostatic dust collection, are removed for top rapping electrostatic more specifically to one kind
The cathode construction of dirt device.In addition, the utility model further relates to a kind of electrostatic precipitator including above-mentioned cathode construction.
Background technology
Electrostatic precipitator is the corollary equipment of thermal power plant indispensability, its function is will be in flue gas discharged from coal-fired boiler
Particle dust is removed, and is to improve environmental pollution, improve air matter to which the fume amount being discharged into atmosphere be greatly lowered
The important environmental protection equipment of amount.
Electrostatic precipitator is mainly by shell, dedusting electric field (abbreviation electric field), anode rapping, cathode rapping, high voltage direct current
The part such as source, ash bucket forms, and Anodic is alternately arranged with cathode, constitutes the core of electrostatic precipitator --- dedusting electricity
.The size of processing exhaust gas volumn, an electrostatic precipitator generally comprise several electric fields run independently of each other as needed, these
Electric field is evenly arranged at matrix in electrostatic precipitator.The anode of each electric field is arranged in juxtaposition by array and is hung directly from electrostatic
Anode plate composition on shell of dust remover, and pass through the ground connection of shell realization anode.
When electric field is run, corona ionization occurs for the tip of cathode line, and generation is a large amount of negatively charged near tip
Particle and a small amount of positively charged particle.Under the action of electric field force, charged particle is to anode and cathode displacement, and mobile
Keep its charged with the dust collision in flue gas in the process, Charged particle is oriented to anode and cathode respectively under the action of electric field force
Mobile and in cathode line and anode plate " absorption ".When " adsorption layer " runs up to certain thickness, pass through the rapping of cathode, anode
Effect, dust particles layer lean on gravity and fall into ash bucket, and the dust particles in ash bucket are delivered to grey library by ash-transmission system and store.

When, enterprise can be caused to seriously affect.On the other hand, be evenly arranged in electrostatic precipitator in matrix due to electric field, when along
When two adjacent electric fields of flow of flue gas direction arrangement can not work normally, the amount of gathering dust of subsequent electric field can greatly increase simultaneously
Defeated grey ability maximum more than design, the grey position in ash bucket will constantly increase, when grey position reaches the minimum altitude of electric field and by cathode
When anode is snapped into together, the electric field as short circuit and can not run.Once the electric field on flue gas access is all stopped transport, hair
Motor group is by forced outage.
Currently, in addition to selection helix is as the electric field of cathode line, it there is no effective measures that can normally be transported in other electric fields
In the short trouble of electrostatic precipitator external treatment failure electric field under capable situation.
