Description
Technical field
The invention belongs to flue gas ash removal technical fields, are related to a kind of wet electrical dust precipitator insulated case hot wind isolating device.
Background technique
National Development and Reform Committee in 2014, Chinese Ministry of Environmental Protection, National Energy Board " coal electricity energy-saving and emission-reduction upgrading and transformation action plan
(2014-2020) " (No. 2093 texts) and " implementing in full coal-burning power plant's minimum discharge and reducing energy consumption programme of work " (ring hair
[2015] No. 164) documentation requirements, power industry carrying out coal-burning power plant's minimum discharge transformation.Coal-burning power plant's atmosphere pollution
Minimum discharge technology is from experiment and demonstration to the time that only experienced 1 year is promoted and applied, with the expansion of minimum discharge implement scale
Greatly, multiple technologies route plan has application.Wet dust removal technology is as flue dust minimum discharge main technological route complete
The multiple power plant's successful applications of state are implemented, and the technology is to flue dust, fine particle PM2.5, sulfuric acid mist, the multiple pollutants such as heavy metal Hg
Control effect is significant.Wet electrical dust precipitator is not grown in coal-burning power plant's large-scale application time in recent years as a new technology, is closed
Key technology problem still needs to further perfect by continuing to optimize in application process.
Wet electrical dust precipitator work flue gas condition is different from dry electric precipitation device.Wet electrical dust precipitator is arranged in wet desulphurization
After device, negative direct current high voltage is conveyed to electric field space by high-voltage rectifying transformer, is ionized by space gases, powder in wet flue gas
After dirt particle and droplets particles are charged under the action of electric field force, it collects in pole surface of gathering dust, is removed by periodic cleaning.Wet type
Cathode of electric dust collector system insulation is directly contacted with wet flue gas, and it is steady that the drying regime of porcelain insulator will directly affect equipment operation
Qualitative and performance indexes, therefore the design of insulated case hermetically drying is one of wet electrical dust precipitator key technology.Wet flue gas is such as
It condenses into will lead to be formed in insulator surface in insulated case, in addition the absorption of the dunghills such as dust is on the insulator, insulator
Decreasing insulating, when operation, cause edge flashing to discharge.Frequent flashover not only will affect high voltage power supply stable operation and
Dust removing effects but will cause the damage of unrepairable to insulator.Keeping method dry in insulated case at present is in insulated case
Hot air sweeping device is set on cabinet, i.e., is passed through hot wind carry out table to case inner insulator by opening aperture in insulated case tank surface
Face purging, the quantity and position angle of purging are difficult to realize uniformly purge to spool insulator, and hot wind consumption is big, and dry heat
Wind has dehydration after contacting with the saturation dust-laden wet flue gas entered in insulated case, will stick in insulator surface, is unable to reach
The dry requirement and cleaning that wet flue gas is effectively isolated require, after long-play, the decline of insulator dielectric performance, and wet-esp
Device high voltage supply is unstable, and dust removing effects is caused to decline.Therefore how to effectively improve insulated case drying property is wet-esp
One of key technology of device.
Summary of the invention
It is an object of the invention to overcome the above-mentioned prior art, provide a kind of for wet electrical dust precipitator insulation
