Its simple structure, the modern design through the original vortex device of electrostatic precipitator principle cooperation, realizes the defogging dust removal operation of the flue gas of liquid drop, the homocharge principle of repelling each other reduces the flue gas and adsorbs the problem on the impeller, convenient and practical simultaneously.
Description
Technical field:
This utility model relates to craft dust removal technical field, is specifically related to a kind of coal-burning power plant Wet chimney except mist dust arrester.
Background technology:
At present, the flue gas desulfurization device more than 90% of domestic large coal-fired power plant unit uses limestone-gypsum wet desulfuration technique, containing SO in the wet flue gas after desulfurization2、SO3, the highly acid material such as HCl.After desulfurization, flue-gas temperature is in below acid dew point, and chimney now is " Wet chimney ".Flue gas in Wet chimney is easily generated has corrosive sulphuric acid, sulfurous acid and hydrochloric acid solution.For not having the desulphurization system of flue gas heat-exchange unit, flue-gas temperature is lower, and fume gas condensation acid solution is carried over chimney with the form of little droplet with fume emission, flies away in surrounding, and neighbouring residents ' health and property safety are constituted serious threat.
For the problems referred to above, in the patent of Application No. 201520840097.7, make solution, use two groups of vortex devices carry out drop flue gas except mist dedusting operation, but owing to the flue gas of drop comprises substantial amounts of smoke particle, through mutual collision, rubbing self creates a certain amount of electric charge, it is readily adsorbed on the inwall of chimney and the impeller of vortex device, causes, except mist efficiency of dust collection reduces, seriously causing equipment to be paralysed.
Utility model content:
The purpose of this utility model is the defect for prior art and deficiency, there is provided a kind of coal-burning power plant Wet chimney except mist dust arrester, its simple in construction, novel in design, by electrostatic precipitation principle coordinate original vortex device, it is achieved the flue gas of drop except mist dedusting operation, the principle that homocharge repels each other simultaneously, reduce flue gas absorption problem on impeller, convenient and practical.
In order to solve the problem existing for background technology, a kind of coal-burning power plant of the present utility model Wet chimney is except mist dust arrester, and it comprises chimney, lower bracing frame, the first eddy current rotary apparatus, upper support frame, the second eddy current rotary apparatus, connecting rod；The bosom of described chimney is fixed with the first eddy current rotary apparatus by lower bracing frame, and the inner upper end of chimney is fixed with the second eddy current rotary apparatus by upper support frame, is connected by connecting rod between the first eddy current rotary apparatus and the second eddy current rotary apparatus；It is characterized in that: it also comprises high voltage induction electrode network, electrostatic attraction electrode sheet, water jets under high pressure shower nozzle；Described high voltage induction electrode network is arranged on the inside bottom of chimney, and one end ground connection of high voltage induction electrode network；It is provided with electrostatic attraction electrode sheet on the first described eddy current rotary apparatus and the revolving vane of the second eddy current rotary apparatus；Described water jets under high pressure shower nozzle is arranged on the lower end of the second eddy current rotary apparatus, and is fixed on inner wall of stack.
The electrode of described high voltage induction electrode network is identical with the electrode on electrostatic attraction electrode sheet.
The jet blower of described water jets under high pressure shower nozzle is just to water smoke accumulation point in the middle of the second eddy current rotary apparatus.
Compared with prior art, the beneficial effects of the utility model are: its simple in construction, novel in design, original vortex device is coordinated by electrostatic precipitation principle, realize drop flue gas except mist dedusting operation, the principle that homocharge repels each other simultaneously, reduces flue gas absorption problem on impeller, convenient and practical.
