Description

A kind of filtrating equipment of flue gas of annealing furnace

Technical field

Annealing device technical field is the utility model is related to, more particularly to a kind of filtrating equipment of flue gas of annealing furnace.

Background technology

Annealing is referred to metal being heated slowly to certain temperature, keeps enough time, then cooled down with Reasonable Speed.Mesh Be reduce hardness, improve machinability；Residual stress is eliminated, stable dimensions, reduces deformation and crackle tendency；Refinement is brilliant Grain, tissue is adjusted, eliminate tissue defects.Existing annealing furnace daily caused by substantial amounts of flue gas, containing poisonous in these flue gases Metal, carbon-bearing particulate matter etc., the air ambient of surrounding can be influenceed when these flue gases are displaced into air.

Utility model content

The purpose of this utility model is to provide a kind of filtrating equipment of flue gas of annealing furnace, can more efficiently filter flue gas In impurity.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of flue gas of annealing furnace Filter, including the smoke exhaust pipe positioned at annealing furnace upper end, are provided with air exhauster on the smoke exhaust pipe, the air exhauster is away from institute The side for stating smoke exhaust pipe is provided with the first horizontally extending dispatch pipe, and the first dispatch pipe is away from the air exhauster The the second dispatch pipe vertically extended is provided with one end, is provided with activated charcoal strainer in the second dispatch pipe, institute The second dispatch pipe is stated to be provided with for collecting what is fallen from the activated charcoal strainer close to one end of the first dispatch pipe The collection bucket of impurity.

By using such scheme, the filtrating equipment of flue gas of this kind of annealing furnace using air exhauster by the flue gas in annealing furnace from Draw on smoke exhaust pipe, subsequent flue gas is entered in the first dispatch pipe, can finally enter the vertically extended Two dispatch pipes, now send the activated charcoal strainer in pipe using second row, and there is activated charcoal strainer fabulous absorption to make With, you can the debris such as the toxic metals in flue gas, carbon-bearing particulate matter are adsorbed；While leaned on using the second dispatch pipe is arranged on Collection bucket on nearly first dispatch pipe one end, when the debris in activated charcoal strainer is adsorbed onto constant weight, debris can be Fallen under in the presence of gravity in collection bucket, operating personnel can be collected by collection bucket to debris, final to can be achieved Relatively efficiently filter the impurity in flue gas.

It is of the present utility model to be further arranged to：The section of the activated charcoal strainer is in the V-shaped of opening upwards.

By using such scheme, using the V-shaped section of activated charcoal strainer set in opening upwards, work as flue gas When being displaced at activated charcoal strainer, the wind of the windage of the activated charcoal strainer of V-shaped compared to the activated charcoal strainer of plane Can be smaller for resistance, so influence of the activated charcoal strainer of V-shaped to wind-force is smaller, advantageously ensure that the row of flue gas Put.

It is of the present utility model to be further arranged to：Multiple spray heads, multiple sprays are provided with the first dispatch pipe Drench bearing of trend uniform intervals distribution of the head along the first dispatch pipe.

By using such scheme, preliminary filtering is carried out to flue gas using multiple spray liquids in the first dispatch pipe, when After second dispatch pipe carries out secondary filter to flue gas, flue gas can be cleaned more, so as to be advantageously implemented more efficient filtering Impurity in flue gas.

It is of the present utility model to be further arranged to：The downside inwall of the first dispatch pipe is in towards the one of the collection bucket Roll obliquely.

By using such scheme, when spraying the water to get off on spray head and falling in the downside inwall of the first dispatch pipe, i.e., It can be wandered with inclined first dispatch inside pipe wall into collection bucket, so as to which the convenient sewage to carrying debris is cleared up, Also reduce the possibility that sewage proceeds in air exhauster simultaneously.

It is of the present utility model to be further arranged to：The collection bucket detachably connects on one end away from the second dispatch pipe End cap is connected to, the delivery pipe for being communicated with the external world is provided with the end cap.

By using such scheme, when needing to clear up in end cap the debris deposited, end cap is taken off can clear up it is miscellaneous Thing；When the sewage that spray head is fallen is flowed into collection bucket, sewage discharge can be gone out by delivery pipe.

It is of the present utility model to be further arranged to：The week side of boss of the second dispatch pipe away from described first dispatch pipe one end is set More connecting poles are equipped with, end of the connecting pole away from the second dispatch pipe is provided with shelves lid.

By using such scheme, end face of the second dispatch pipe away from the first dispatch pipe is covered using shelves lid, from And the opening for reducing other things from the second dispatch pipe is dropped into the second dispatch pipe, while the gap between more connecting poles It can be discharged again for the flue gas cleaned.

It is of the present utility model to be further arranged to：The second dispatch pipe is set close to the side of the activated charcoal strainer There is observation window.

By using such scheme, the sight for being positioned close to set on the second dispatch pipe of activated charcoal strainer side is utilized Window is examined, operating personnel can be observed to accumulate the thickness of debris in activated charcoal strainer by observation window；When debris accumulation is blocked up Again without because when gravity is fallen into collection bucket, operating personnel can tap the second dispatch pipe body, so that debris is from work Fallen into after being shaken off on property charcoal screen pack in collection bucket.

In summary, the utility model has the advantages that：The filtrating equipment of flue gas of this kind of annealing furnace utilizes first Multiple spray heads in dispatch pipe are carried out after once filtering to flue gas, utilize the V-shaped activated charcoal strainer in the second dispatch pipe Carry out secondary filter；Simultaneously using collection bucket of the second dispatch pipe on first dispatch pipe one end is arranged on, when activated carbon mistake Debris on filter screen is fallen in collection bucket down under gravity；And the spray liquid sprayed flows into along the first dispatch pipe Into collection bucket, operating personnel can be collected by collection bucket to debris, final to can be achieved relatively efficiently to filter cigarette Impurity in gas.
