Description
Technical field
The utility model is related to a kind of catalytic unit, and flue gas is circulated denitration in particular to one kind simultaneously can be automatic
The catalytic unit of dedusting.
Background technology
The coal fuel that power plant, boiler are used can produce the various oxides of nitrogen after combustion, be exhausted directly to meeting in air
Serious pollution environment, it is therefore desirable to which denitration process is carried out to combustion tail gas.Current denitration generally uses SCR
Method（SCR）, this method needs to use denitrating catalyst.Utility model patent 201420281803.4 discloses a kind of Flapper type and taken off
It is the half high of square passageway mid-height that height is interval with the moulding body of denox catalyst, each the week side of boss wall of square passageway four
Plate washer.This moulding body of catalyst with it is big by catalyzed gas contact surface area, time of contact is long, and denitration reaction is more thorough.This
Outside, the moulding body of the isostructural catalyst of grid, needle bar, baffle plate is also set up in square passageway, purpose is all increase catalysis
The time of contact and contact area of agent and flue gas, lift catalytic effect.The moulding body of these catalyst is made up of denitrating catalyst, multiple
Miscellaneous structure to expend catalyst amount larger, and flue gas in advance by making pace slack-off after various stops,
Reaction time is partially long, and catalytic efficiency is relatively low, the dust in flue gas is more trapped in catalyst, easily causes resistance
Plug.
Utility model content
The purpose of this utility model is to provide one kind from the reciprocating denitration catalyst device of dedusting, and the catalytic unit uses catalysis
Agent consumption is few, high catalytic efficiency, and is conducive to removing the dust being detained in flue gas.
To achieve the above object, the utility model takes following technical scheme：
One kind is from below the reciprocating denitration catalyst device of dedusting, including catalyst container, upper outlet body and lower cover, catalyst container with
Cover body is connected, and is connected above catalyst container with upper outlet body, it is characterised in that by catalysis grid in three-dimensional side in the catalyst container
Connect up extension to form, equipped with catalysis ball in catalysis grid, catalysis ball warp is crossed transverse axis and is connected on the crossbeam of catalysis grid both sides,
Air inlet is left in catalyst container transverse direction side, and exhaust outlet is left in relative side, and the air inlet and exhaust outlet are with being catalyzed grid
Relatively, air inlet is connected by the road with exhaust outlet outside catalyst container, and blower fan, the catalysis grid and catalysis ball are equipped with pipeline
It is made by denitrating catalyst.
It is preferred that, the catalysis ball is hollow catalysis ball.
It is preferred that, air-vent is left on the catalysis ball, dust-collecting box is left on the lower cover.
When in use, flue gas enters catalyst container from lower cover and is in contact with catalysis grid and catalysis ball above-mentioned catalytic unit
And denitration reaction is occurred by catalysis, flue gas successively rises, while blower fan can be formed flue gas reciprocal flowing in catalysis grid
Circulation, this is conducive to flue gas to be in contact from different catalysis grids and catalysis ball, makes reaction more fully and completely, while flue gas is followed
Circulation is dynamic can also to drive catalysis ball rotation, be more beneficial for removing the dust sticked on catalysis ball, dust is fallen and is concentrated
In the dust-collecting box of lower cover.This catalytic unit is less using catalyst amount, and catalytic efficiency is higher.

Embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
As shown in Figure 1, Figure 2 and Figure 3, this from the reciprocating denitration catalyst device of dedusting include catalyst container 1, upper outlet body 3 and under
Cover body 2, catalyst container 1 is cube shape, and upper outlet body 3 is connected with the top surrounding sealing of catalyst container 1, under lower cover 2 and catalyst container 1
Fang Sizhou sealings are connected, and dust-collecting box 4 is left on lower cover 2, and the dust fallen on ball is catalyzed for access.In catalyst container 1
Interior to connect extension on three-dimensional by catalysis grid 5 and form, equipped with catalysis ball 6 in catalysis grid, catalysis ball 6 connects by transverse axis
It is connected on the crossbeam of catalysis grid both sides, it is on hollow catalysis ball, catalysis ball that ball is catalyzed in a preferred scheme of the present embodiment
Leave air-vent 7.Catalysis grid and catalysis ball are made by denitrating catalyst.
Air inlet 8 is left in the horizontal side of catalyst container 1, and exhaust outlet 9 is left in relative side, and air inlet and exhaust outlet are with urging
Change grid relative, air inlet 8 10 is connected by the road with exhaust outlet 9 outside catalyst container, blower fan 11 is equipped with pipeline, blower fan 11 can
So that flue gas reciprocal flowing in catalysis grid forms circulation, this is conducive to flue gas to connect from different catalysis grids and catalysis ball
Touch, make reaction more fully and completely, while flue gas recirculation flowing can also drive catalysis ball rotation, be more beneficial for removal and stick to
The dust on ball is catalyzed, dust is fallen and is concentrated in the dust-collecting box of lower cover.
The present embodiment is the explanation that the utility model is conceived and realized, is not limited, in this reality
With under new design, the technical scheme without essence conversion is still in protection domain.
