Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
The present invention horizontal single hop modularity flue gas desulfurization and denitrification adsorbent equipment, including horizontal tank body, on described tank body
Lower two ends are provided with blow vent；It is provided with adsorbent in described tank body.The present invention horizontal single hop modularity flue gas desulfurization and denitrification
After absorption/regenerating unit can require by using the series connection of this modular unit and parallel connection according to different fume treatment, carry out
Desulfurization and the regeneration of adsorbent, whole process active coke adsorbent is fixed in a device, it is not necessary to mobile, it is to avoid activated coke
A large amount of losses, are substantially reduced operating cost.
The operation principle of the present invention is as follows:
SO2Adsorption process: activated coke desulfurization is the dry FGD process technology of a kind of resource.This technology is described
Horizontal single hop modularity flue gas desulfurization and denitrification absorption/regenerating unit utilizes there is unique absorption and the activated coke pair of catalytic performance
SO in flue gas2Carry out selective absorption, the SO of ADSORPTION STATE2In flue gas, oxygen and steam are oxidized under conditions of existing
H2SO4And be stored in activated coke hole, complete flue gas desulfurization.
2SO2+O2+2H2O=2H2SO4
Denitrification process: the flue gas after one section of horizontal adsorbent equipment enters the horizontal adsorbent equipment of two-stage nitration, is spraying into dilution
Under the conditions of ammonia, the NOx in flue gas occurs SCR reduction reaction to generate nitrogen and water under the catalytic action of activated coke, it is achieved denitration.
4NO+4NH3+O2=4N2+6H2O
2NO2+4NH3+O2=3N2+6H2O
Desorption process: the activated coke absorption SO in described horizontal single hop modularity desulfurization absorption/regenerating unit2After, adding
In the case of heat, its H adsorbed2SO4React with C (activated coke) and be reduced to SO2, activated coke is activated again thus extensive simultaneously
Its absorption property multiple, recycles.
2H2SO4+ C=2SO2+CO2+2H2O
Whole sweetening process, the activated coke one in this use novel horizontal single hop modularity desulfurization absorption/regenerating unit
No longer move after secondary filling, thus avoid breakage.
On tank body, the position of corresponding adsorbent is provided with manhole, for maintenance and the dress of active coke adsorbent of device
Unload.
Improve further as the present invention, between described adsorbent and tank body lower end, be provided with filter course.Described
Filter course is arranged on above adsorbent, can filter a small amount of broken burnt microgranule, it is ensured that discharge exhaust gas dust content is up to standard.Filter course can
To be made up of screen support grid and filter screen.
Improving further as the present invention, in described tank body, bottom is provided with adsorbent supportive grid, described
Adsorbent is arranged on adsorbent grid.Above-mentioned adsorbent is active coke adsorbent, and active coke adsorbent has under low temperature to be inhaled
SO in attached flue gas2Ability and under finite concentration ammonia atmosphere the ability of catalytic elimination NOx, there is regeneration capacity simultaneously.
Improve further as the present invention, air inlet Distribution Layer is set between described adsorbent and tank body lower end.Institute
The air inlet Distribution Layer stated is arranged in the lower section of described horizontal tank body, and described air inlet Distribution Layer at least includes: by between organize axially more
Distributive lattice screen composition every distribution.Air inlet distribution grid is formed by organizing the flase floor being distributed at a certain distance more, described air inlet
Distribution grid is arranged on top and the air inlet distribution grid bracing frame of described low head, to the turbulent cigarette entered at low head
Gas carries out preliminary rectification and distribution.Air inlet distribution grid bracing frame is welded to connect with described tank body inner frame, and described air inlet distributes
Grid is formed by organizing module more, is positioned on air inlet distribution grid bracing frame, it is not necessary to welding, easy for installation, fast.
It is also preferred that the left what described air inlet Distribution Layer included arranging from the bottom to top: air inlet distribution grid bracing frame, air inlet distribution
Grid, redistributor bracing frame and redistributor.Above-mentioned redistributor is made up of multiple regularly arranged tubular structures, described again
Allotter is arranged on top and the redistributor bracing frame of described air inlet distribution grid, carries out two to entering adsorber flue gas
Secondary rectification, it is ensured that flue gas is uniformly through described tank interior activity focus layer.Described redistributor bracing frame and described tank body internal skeleton
Frame is welded to connect, described in enter redistributor and formed by organizing module more, be positioned on redistributor bracing frame, it is not necessary to welding,
Easy for installation, fast.
For the ease of installing, improve further as the present invention, tank body is provided with described undersetting and upper bracket, institute
Stating undersetting and the fixing connection of external frame, described upper bracket is connected by elastic device and external frame.
The work process of the present invention is as follows:
Step 1, horizontal single hop modularity flue gas desulfurization and denitrification absorption/regenerating unit is made to be in adsorbed state
Flue gas is made to enter the tank body of horizontal single hop modularity flue gas desulfurization and denitrification absorption/regenerating unit by lower blow vent
In, owing to presetting active coke adsorbent in tank body, so utilize and there is unique absorption activated coke with catalytic performance to cigarette
SO in gas2Carry out selective absorption, the SO of ADSORPTION STATE2In flue gas, oxygen and steam are oxidized under conditions of existing
H2SO4And be stored in activated coke hole；Activated coke adsorption layer is equivalent to high-efficient granule layer filter simultaneously, at inertial collision
With under interception effect effect, a small amount of dust granules in the flue gas after udst separation is captured at the internal different parts of bed, complete
Become flue gas desulfurization and udst separation.Flue gas after purification is discharged by upper vent.
Step 2, horizontal single hop modularity flue gas desulfurization and denitrification absorption/regenerating unit is made to be in reproduced state
After making heating, regeneration gas upper vent above tank body enters, and adsorbs SO2After activated coke, at heating regeneration gas
Under heating state, its H adsorbed2SO4React with C (activated coke) and be reduced to SO2, simultaneously activated coke be activated again thus
Recover its absorption property, recycle.And the flue gas after desorbing is exported by the lower blow vent below tank body, can be used for antacid
Deng.So, regenerative process completes.
Step 3, make said process persistently be alternately accomplished can to realize flue gas is carried out desulfurization.
The layout of the horizontal single hop modularity flue gas desulfurization and denitrification absorption/regenerating unit of the present invention is more flexible, Ke Yiyong
In absorption SO2, another vertical single hop modularity desulfurization adsorbent equipment of arranged in series can be used for removing NOx.During production, two
Device one absorbing unit of composition, is simultaneously used for the absorption of harmful substance；These two devices also can form another desorbing simultaneously
Unit, for adsorb saturated after activated coke regeneration.Absorbing unit and desorption unit mutually switch, and jointly complete harmful substance
Removing and the regeneration cycle of activated coke.
Below in conjunction with embodiment, the present invention is further illustrated.
