China is a country using coal as main energy sources, and coal-fired thermal power generation is the important channel that coal in China is utilized
One of, it is well known that contain SO in the flue gas that coal-burning boiler is discharged2, the pollutant such as NOx and heavy metal (Hg and Ag),
The primary pollution source of air and soil pollution is increasingly becoming, with social progress and economic development, thermal power plant is to atmospheric environment
Influence has been received by the common concern of people, thus the influence for being effectively reduced pollutant emission to improve to environment be China or even
The severe challenge that the sustainable development of world energy sources field is faced.
At present, the Treatment process of flue gas or industrial tail gas is more, wherein comparative maturity and representative desulfurization technology
There are limestone-gypsum method, ammonia process, Dual alkali etc..The selective catalytic reduction method of purification techniques (SCR), non-selective catalytic are also
Former method (SNCR) and low nitrogen burning method etc..The technology of demercuration mainly has chemical precipitation method and chemical oxidization method.
Prior art generally realizes that each unit is independent of each other to desulphurization and denitration, demercuration using independent functional unit,
Function is independently realized, which results in construction cost is high, floor space is big, removal efficiency is low, manipulate the defects such as expense height.
Utility model content
The utility model for existing flue gases purification exist not enough there is provided a kind of purification efficiency is high, effect is good
Smoke eliminator with aeration dome.
Band of the present utility model is aerated the smoke eliminator of dome, using following technical scheme：
The device, including housing；Smoke inlet is provided with the top of housing, bottom is provided with exhanst gas outlet, housing
Aeration dome, rectifier and packing layer are disposed between smoke inlet and exhanst gas outlet from top to bottom；Hull outside is set
Have and be connected with circulating pump on the circulation pipe of connection housing bottom, circulation pipe；It is provided with and is connected with circulation pipe above aeration dome
Top drain pipe, be provided with the bottom drain pipe being connected with circulation pipe, bottom drain pipe below packing layer and spray be distributed with
Head.
The smoke inlet and exhanst gas outlet are in vertical state.
The top drain pipe goes out mouth down, consistent with flue gas approach axis.
The first spray eliminator is provided between the rectifier and packing layer, for being cleaned to packing layer, it is ensured that
Catalytic reaction efficiency.
Demister is provided with the exhanst gas outlet, the both sides of demister set the second spray eliminator.Utilize the second spray
Clarifier is drenched to demister periodic cleaning, it is ensured that except fog effect.
The rectifier is cellular structure.
Housing bottom is loaded with absorbing liquid, and absorbing liquid is delivered to circulation pipe by circulating pump, and by top drain pipe with
Portion's drain pipe sprays.Top drain pipe sprays absorbing liquid in the top of aeration dome, produces aeration effect, strengthens gas-liquid folder
Band so that clean-up effect is more excellent.Absorbing liquid is atomized by the nozzle on the drain pipe of bottom, strengthens the contact with flue gas.Absorbing liquid
Enter rectifier by the gap being aerated between dome and inner walls, it is rectified after under drop down onto cigarette in packing layer, absorbing liquid
The filled layer absorption of dirt, then drops down onto housing bottom, recycles.Flue gas after purification is discharged by exhanst gas outlet.
The utility model is entered with aeration dome, flue gas by top, bottom discharge, is had the following advantages that：
1. aeration dome makes circulating absorption solution occur strong atomization, so that gas-liquid contact is more abundant, removing is improved
Purification efficiency.
2. enclosure interior is constantly washed away because circulating absorption solution, therefore non flouling behaviour or blocking.
