China is a country with 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,
Independently realize function, which results in construction cost it is high, floor space is big, removal efficiency is low, manipulate the defects such as expense is high.
The content of the invention
The deficiency that the present invention exists for existing flue gases purification, there is provided a kind of purification efficiency is high, effect is good has
It is aerated the smoke eliminator of effect.
Smoke eliminator with aeration effect of the invention, 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
There is the circulation pipe of connection housing bottom, circulating pump is connected with circulation pipe；It is provided with above aeration dome and is connected with circulation pipe
Top drain pipe, the bottom drain pipe being connected with circulation pipe is provided with below packing layer, spray is distributed with the drain pipe of bottom
Head.
The smoke inlet is with exhanst gas outlet 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.Using 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.Be atomized for absorbing liquid 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 packing layer, the cigarette in 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 present invention is entered with aeration dome, flue gas by top, bottom discharge, is had the following advantages that：
1. aeration dome makes circulating absorption solution that strong atomization to occur, so that gas-liquid contact is more abundant, improves removing
Purification efficiency.
2. enclosure interior constantly washing away because of circulating absorption solution, therefore non flouling behaviour or blocking.

Specific embodiment
As shown in figure 1, the present invention has the smoke eliminator of aeration effect, including housing 13.The top of housing 13 sets
Smoke inlet 1 is equipped with, bottom side is provided with exhanst gas outlet 11, and smoke inlet 1 is with exhanst gas outlet 11 in vertical state.Housing 13
Aeration dome 3, rectifier 4 and packing layer 5 are disposed between inherent smoke inlet 1 and exhanst gas outlet 11 from top to bottom.Shell
The bottom of body 13 is connected by circulating pump 7 with circulation pipe 14.The top of aeration dome 3 is provided with top drain pipe 2 in housing 13,
The lower section of packing layer 5 is provided with bottom drain pipe 6, top drain pipe 2 and bottom drain pipe 6 are connected with circulation pipe 14.On
Portion's drain pipe 2 goes out mouth down, with flue gas approach axis consistent.The bottom of housing 13 is loaded with absorbing liquid 8, and absorbing liquid 8 is by following
Ring pump 7 is delivered to circulation pipe 14, and is sprayed by top drain pipe 2 and bottom drain pipe 6, forms the removing of two-stage flue dust.Top goes out
The outlet of liquid pipe 2 is arranged on the top of aeration dome 3, and absorbing liquid 8 is sprayed along flue gas approach axis, forms first order flue dust and takes off
Remove；Because the gap between the aeration dome 3 and the inwall of housing 13 of arc is gradually reduced, aeration effect is then produced, strengthened
Entrained liquid so that clean-up effect is more excellent.Bottom drain pipe 6 forms the removing of second level flue dust, connects multiple on bottom drain pipe 6
Nozzle, absorbing liquid 8 is atomized, and strengthens the contact with flue gas, and the bottom of housing 13 is fallen directly into after absorbing liquid 8 and smoke reaction
Portion.Absorbing liquid 8 enters rectifier 4 after by aeration effect by the gap being aerated between dome 3 and the inwall of housing 13,
Dropped down onto on packing layer 5 under after rectified, the filled layer 5 of the flue dust in absorbing liquid 8 is adsorbed, and then drops down onto housing bottom, circulation
Use.
Rectifier 4 can be divided into the two-layer at interval, every layer of 200 millimeters of clear height, 50 millimeters of midfeather.Every layer of rectifier 4
Section uses honeycomb fashion, and upper strata is the regular hexagon of 400 millimeters of the length of side, and lower floor is regular hexagon that the length of side is 300 millimeters.In order to
It is easy to dismount, overhauls, every layer of rectifier 4 is divided into some 1200 millimeters * 1200 millimeters of module, the side wall of housing 1 is provided with 1500
