Description
Technical field
The utility model relates to electric precipitator fields, and in particular, to a kind of manhole door mechanism for electric precipitator.
Background technique
Electric precipitator is the essential crucial large scale equipment such as thermal power plant, steel mill, chemical plant, cement plant, can be had
Effect removes the dust in industrial smoke, and the fume amount being discharged into atmosphere is greatly lowered, and is to reduce pollution, improves environment, mention
The important environmental protection equipment of high air quality.The working principle of electric precipitator is the strong electrical field generated using high voltage direct current, makes work
Gas molecule in industry flue gas is ionized into a large amount of electronics and ion, mobile to the two poles of the earth under the action of electric field force, in moving process
In the dust particles encountered in air-flow keep its charged, Charged is separated with air-flow to opposite polarity pole under electric field force effect
Plate or polar curve movement, Charged are adsorbed on pole plate or polar curve when reaching pole plate or polar curve by electrostatic force, pass through rapping apparatus
Dust is set to fall into ash bucket, to make gas cleaning.Electric precipitator ontology main component includes: smoke box system, corona electrode systems, receives
Dirt electrode systems, trough plate system, ash-slag disposal system, shell (including manhole door), shell heat preservation and ladder landing platform etc..
The main function of electric precipitator manhole door is that maintenance personal is facilitated to carry out installation and debugging and dimension to electric precipitator ontology

As the number that electric precipitator manhole door opens and closes increases, personnel are frequently passed in and out from manhole door in addition, will lead to people
Insulating layer around the hole original single seal failure of door and manhole door is damaged, these problems be easy to it is ignored, if it find that
Not in time or maintenance and repair not in time, easily occur leaking out and dew condensation phenomenon, and then efficiency of dust collection decline and equipment quilt occur
The problem of corrosion, can lead to manhole door and its surrounding shell is corroded rotten wear when situation is serious.Problem above is in actual operation
It frequently encounters, the method for usually solving problems is system shutdown, from electric field inside repair welding leak source.But this method is deposited
It is exactly that electric field inner space is narrow in a very big problem, it is flat in electric field insider row that operation, especially leak source are carried out in inconvenience
At this moment platform is in the following, need from ash bucket scaffolding ability weld job；Sometimes maintenance personal thinks the scaffolding inside ash bucket
It is too bothersome, nethermost leak source not repair welding is then simply put down, so that maintenance work is not in place, is not thorough, or even loses meaning；
Certainly, at this moment maintenance personal can also need first to remove outer heat insulation layer, find leak source from electric precipitator hull outside repair welding leak source
After carry out repair welding, also to restore outer heat insulation layer later, it is more troublesome.If leak source is under electric precipitator hull outside people's row platform
Face also needs scaffolding repair welding, even more troublesome.
