Abstract
The utility model provides a kind of molten iron pretreatment desulfurizing flue dust nitrogen seal device, the nitrogen seal device is circular ring shape, smoke chamber body is caught up in the connection of smoke seal cavity lower end, lower rifle hole is had among annulus, a circle hanging ring is equipped with along outside on smoke seal cavity, it smoke seal chamber outer wall and catches up with and is connected to gas source access tube on cigarette chamber outer wall respectively, flat spray-hole is provided on smoke seal cavity inner wall, catches up with and is provided with oblique spray-hole on the skew wall of smoke chamber body lower end.The utility model can fundamentally solve the problems, such as that desulfurization and dedusting effect is poor, and it is excessive to can effectively avoid flue dust, greatly improvement operating environment, it is ensured that environmental protection index is up to standard.
Description
Technical field
The utility model belongs to smelting field of dust removal equipment more particularly to a kind of encapsulation of molten iron pretreatment desulfurizing flue dust nitrogen
It sets.
Background technique
The process of hot metal desulfuration blowing system desulfurization mainly using calcium powder, magnesium powder carry out desulfurization, due to calcium powder, magnesium powder with
After molten iron reacts, volume of smoke is generated, flue dust is dusted by cleaning shaft, at the petticoat pipe hole that spray gun is passed through,
Also a large amount of excessive flue dust are generated, since environmental requirement is increasingly stringenter, this part of flue dust also forms red cigarette in factory building roof,
The health of operating personnel is not only influenced, while also greatly polluted environment.
Summary of the invention
The utility model, which is intended to provide one kind, can solve the problems, such as that desulfurization and dedusting effect is poor, effectively avoid flue dust excessive, protect
Demonstrate,prove the molten iron pretreatment desulfurizing flue dust nitrogen seal device of environment protection standard.
For this purpose, the utility model takes following technical solution:
A kind of molten iron pretreatment desulfurizing flue dust nitrogen seal device, the nitrogen seal device are circular ring shape, have lower rifle among annulus
Hole, nitrogen seal device include smoke seal cavity, catch up with smoke chamber body and hanging ring, and smoke seal cavity lower end, which connects, catches up with smoke chamber body, on smoke seal cavity
A circle hanging ring is equipped with along outside, smoke seal chamber outer wall and is caught up with and is connected to gas source access tube on cigarette chamber outer wall respectively, smoke seal cavity
It is provided with flat spray-hole on inner wall, catches up with and is provided with oblique spray-hole on the skew wall of smoke chamber body lower end.
Angle between the oblique injection centerline hole and horizontal plane is 40 °~50 °.
The utility model has the following beneficial effects:
The utility model uses the dual nitrogen seal structure of saparated sulfer ash, can fundamentally solve the difficulty of desulfurization and dedusting effect difference
Topic, it is excessive to can effectively avoid flue dust, greatly improvement operating environment, it is ensured that environmental protection index is up to standard.
Detailed description of the invention
Fig. 1 is nitrogen seal device diagrammatic cross-section；
Fig. 2 is nitrogen seal device top view.
In figure: hanging ring 1, flat spray-hole 3, upper gas source access tube 4, lower gas source access tube 5, catches up with smoke chamber body at smoke seal cavity 2
6, oblique spray-hole 7, lower rifle hole 8.
Specific embodiment
By attached drawing as it can be seen that the utility model molten iron pretreatment desulfurizing flue dust nitrogen seal device is integrally overlooked as a circular ring shape, circle
Lower rifle hole 8 is formed among ring；Mainly by hanging ring 1, smoke seal cavity 2 and smoke chamber body 6 is caught up with to form, the lower end connection of smoke seal cavity 2
Smoke chamber body 6 is caught up with, a circle hanging ring 1 is equipped with along outside on smoke seal cavity 2, is connected to gas source access on 2 outer wall of smoke seal cavity
Pipe 4 is provided with flat spray-hole 3 on inner wall；It catches up with and is connected to lower gas source access tube 5 on the outer wall of smoke chamber body 6, be provided with oblique spray on the skew wall of lower end
Perforation 7, the angle between the center line and horizontal plane of oblique spray-hole 7 are 45 °.
Due to catching up with smoke chamber body 6 to spray nitrogen and horizontal plane shape angle at 45 °, the nitrogen ejected is poly- around spray gun center
At a pressure spot, when flue dust floats to petticoat pipe, flue dust is driven out of petticoat pipe.When the flue dust for catching up with smoke chamber body 6 to escape out reaches envelope
When smoke chamber body 2, this part of flue dust is effectively enclosed in nitrogen seal ring hereinafter, to protect by the nitrogen seal ring of flat 3 horizontal-jet of spray-hole
The effect of dedusting is demonstrate,proved.
