Abstract
The present invention relates to a kind of flue more particularly to carbon industry production aluminium anode, cathode, electrode and the pot type burner exit flues of charcoal element graphitization raw material calcining.Including pot type burner, the last layer quirk of pot type furnace bottom is communicated by interface channel with collection flue, and interface channel includes straight way and bend；Straight way is located at last layer quirk side, and bend is located at collection flue side.Advantages of the present invention effect: collection flue sectional area variation of the present invention not only can substantially reduce the pressure loss of collection flue, can play the balanced action arrived very much simultaneously for the negative pressure of whole stove quirk.
Description
Technical field
The present invention relates to a kind of flue more particularly to carbon industry production aluminium anode, cathode, electrode and charcoal flat band ink
Change the pot type burner exit flue of raw material calcining.
Background technique
In recent years, with the increase year by year of electrolytic cell list tankage and single series production capacity, the single series production capacity of prebaked anode
Also it is gradually increased, the calcining of the first procedure as prebaked anode, pot type burner the Enlargement Tendency is more obvious, on the one hand can be with
Cost of investment is reduced, labor productivity on the other hand can also be increased.One of the advantage of pot type burner technology, which is to produce, to be stablized, base
In different workshop configurations, more and more pot type burners are discharged fume using collection flue end in furnace, but the pot type burner of enlargement
Furnace body length is longer, and for example the pot type furnace length of 76 tanks reaches 46m, is discharged fume using collection flue, but in current flue structure
There are still larger problems, and on the one hand the negative pressure of constant collection flue proximally and distally is inconsistent, and distal end negative pressure is low, seriously affects
Production；On the other hand the current collection flue pressure loss is larger, causes the increase of total blower power consumption.
Summary of the invention
In order to solve the above-mentioned technical problem a kind of pot type burner exit flue proposed by the present invention, it is therefore an objective to be suitable for set
Change the mode that flue gas in quirk enters collection flue in the device of flue end smoke evacuation, reduces the pressure damage of entire collection flue
It loses, while the pressure of balanced remote proximal end, is operated conducive to the temperature adjustment of pot type burner.
A kind of pot type burner exit flue of the invention for the above-mentioned purpose, including pot type burner, the last layer quirk of pot type furnace bottom
It is communicated by interface channel with collection flue, interface channel includes straight way and bend；Straight way is located at last layer quirk side, and bend is set
In collection flue side.
Angle between bend and collection flue is 30-60 °.
Angle between bend and collection flue is 45 °.
Collection flue is closed at one end, the other end be smoke evacuation end, closed one end to discharge fume end collection flue sectional area from
Small to become larger, collection flue bottom is ladder-like.
The variation of collection flue sectional area is to be gradually increased along air current flow direction collection flue inner space volume in ladder
Shape variation.
Change in ladder shape is built using masonry, builds collection flue is arranged in position bottom surface and outside, building materials
For refractory fireclay block.
Advantages of the present invention effect: the present invention changes the mode that original last layer quirk flue gas enters collection flue, passes
The mode of entrance of system is that straight line enters, and angle is 90 °, and this mode causes flue gas movement disorder in collection flue, on section
Flue gas homogeneity is poor, and peak flow rate (PFR) is big.It is along airflow direction oblique cutting mode, greatly that last layer flue gas of the invention, which enters collection flue,
Greatly improve traditional approach there are the problem of.The variation of collection flue sectional area not only can substantially reduce the pressure damage of collection flue
It loses, the balanced action arrived can be played very much simultaneously for the negative pressure of whole stove quirk.
Detailed description of the invention
Fig. 1 is collection flue longitudinal sectional drawing.
Fig. 2 is collection flue horizontal sectional drawing.
In figure: 1, last layer quirk；2, interface channel；3, collection flue；4, straight way；5, bend.
Specific embodiment
The embodiment of the present invention combination attached drawing is described in detail below, but protection scope of the present invention is not by embodiment
It is limited.
A kind of pot type burner exit flue of the present invention as shown in the figure, including pot type burner, the last layer quirk 1 of pot type furnace bottom pass through
Interface channel 2 is communicated with collection flue 3, and interface channel 2 includes straight way 4 and bend 5；Straight way 4 is located at 1 side of last layer quirk, curved
Road 5 is located at 3 side of collection flue.
Angle between bend 5 and collection flue 3 is 30-60 °.Angle between the present embodiment bend and collection flue is
45°。
Collection flue 3 is closed at one end, and the other end is smoke evacuation end 6, collection flue 3 section of the closed one end to smoke evacuation end 6
Product becomes larger from small.
The variation of 3 sectional area of collection flue is to be gradually increased along air current flow direction collection flue inner space volume in ladder
Shape 7 changes, and 3 bottom of collection flue is ladder-like.
Ladder-like 7 variation is built using masonry, builds collection flue is arranged in position bottom surface and outside, building materials
For refractory fireclay block.
