Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of the utility model absorbing cabin.
Fig. 3 is the schematic diagram arranged in parallel of the utility model shell.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Shown in referring to Fig.1, a kind of box-like flue gas pollutant cooperation-removal device of horizontal group, including shell 2, shell 2 is not
Multiple absorbing cabins 3 are each passed through with region, the top of absorbing cabin 3 is connect with feeding bin 1, and the bottom of absorbing cabin 3 is connected with discharge
Storehouse 5, discharge bin 5 connect removal device 6, and the lower section of removal device 6 is provided with conveyer 7；The intermediate position of shell 2 is provided with spray ammonia mouth
B and denitration mixer 8.The shell 2 is arranged in the support 4 of steelframe or concrete.
Referring to shown in Fig. 2, the absorbing cabin 3 is cube structure, and the horizontally arranged of absorbing cabin 3 has 2-5 a wide
Degree is the separate cavities 9 of 10-20mm.It is spaced apart to interlock along the vertical direction in absorbent channel in the absorbing cabin 3
Weld multi-group hole arc support plate 10.
Referring to shown in Fig. 3, shell 2 is arranged in parallel with multiple, and the air inlet of each shell 2 vertically connects inlet manifold 11,
The gas outlet of each shell 2 vertically connects outlet general pipeline 12.
The working principle of the utility model is for using activated coke:
When work, flue gas enters from the import A of shell 2, posteriorly moves under the action of blower in tail portion.First pass around
One absorbing cabin 3.Pollutant effects are removed to reduce dust to rear portion, this storehouse is to carry out powder filtering filtration storehouse using particulate matter.
Filtering absorption of agent can be used the absorbent of other absorbing cabin discharges, convenient for reducing the consumption of new absorbent.Flue gas after dedusting into
Enter second absorbing cabin 3, loads dedicated demercuration absorbent herein for demercuration.Flue gas is after demercuration, into desulfurization zone, by number
A desulfurization absorbing cabin, scrubbing CO_2 enter the area Pen An later.Ammonia is sprayed into via blowing mouth B, passes through thread mixing later
Device 8 mixes ammonia and flue gas uniformly.Through entering denitration region after mixed uniformly flue gas, by several absorbing cabins 3, removing
Outlet C after nitrogen oxides through shell 2 is expelled to rear portion discharge.
Absorbent in absorbing cabin 3 is provided by feeding bin 1, via each 3 channel of absorbing cabin, periodically or by outlet is polluted
Object exit concentration testing result determines efflux time.The absorbent of adsorption saturation via discharge bin 5, removal device 6 and conveyer 7,
Regeneration or unified disposition are sent to after centralized collection.Demercuration dangerous waste absorbent centrally disposes after being collected separately.In operational process, such as
It detects that any 3 temperature of absorbing cabin is excessively high, can determine whether to take being passed through inert gas or the quickly suction of discharge this part after burning
The methods of agent is received to be handled.
When amount of sulfur contenting in smoke is higher, to eliminate influence of the sulfur dioxide to demercuration, can after dedusting next stage absorbing cabin
Desulphurizing activated coke is loaded, a part of sulfur dioxide is first deviate from, later, flue gas enters back into demercuration absorbing cabin and carries out demercuration, and demercuration is inhaled
Receiving agent can be used such as modified load bromine or carries sulphur activated coke, for carrying out the oxidation and absorption of Elemental Mercury.After adsorption saturation, our department
Point dangerous waste activated coke can be handled individually.
The flue gas or leading portion generate to burning natural gas has desulfurizer, big at present such as the sintering machine of steel industry
Have been provided with ammonia desulfuration equipment more.It has not needed to carry out desulfurization again for such, can remove present apparatus leading portion dust-removal and desulfurizing section, directly
Connect arrangement denitration dark zone and denitration region.To activated coke denitrating system, being blown mouth B is spray ammonia mouth.To calcium-base absorbing agent, penetrating
It can be the oxidants such as ozone, hydrogen peroxide, carry out removal of nitrogen oxide by being mixed into denitration region later.
When processing exhaust gas volumn is larger, flue gas is divided equally through inlet manifold 11 in its arrival end and enters each shell 2, in its outlet
Discharge is summarized by outlet general pipeline 12 at end., will also be by screening removal fine powder to activated coke to the absorbent of each blowdown discharge, it
Regeneration is uniformly sent to afterwards.To calcium-base absorbing agent, sends to and centrally dispose after unified collection.
