Description
Technical Field
The invention relates to a bag-type dust collector, in particular to a bag-type dust collector for a converter.
Background
The bag-type dust collector is a dry dust filter. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified.
The converter purifies the flue gas by using a bag-type dust collector and then discharges the flue gas. Then, because the initial speed of the smoke is high and the smoke is concentrated in the middle, the impact on the middle cloth bag is large, so that the middle cloth bag is heavy in load and the edge cloth bags are light in load. Thus, the dust removal efficiency is reduced, the cloth bag is easy to damage, and the service life is shortened.
Disclosure of Invention
In view of the above, the invention provides an ultra-low emission converter bag-type dust collector, which can improve the dust collection efficiency and effect by dispersing the flue gas to balance the load of each bag.
In order to solve the technical problems, the technical scheme of the invention is to adopt an ultra-low discharge converter bag-type dust collector, which comprises a box body and an ash hopper arranged below the box body; a plurality of cloth bags are arranged in the box body, and an ash discharge valve is arranged at the bottom of the ash bucket; the air inlet is arranged on the ash bucket, and the air outlet is arranged at the top of the box body; a plurality of guide plates are arranged in the ash bucket below the cloth bag; the plurality of guide plates are vertically arranged and are parallel to each other and are arranged along the direction vertical to the extending direction of the air inlet; and the guide plates are sequentially arranged from near to far from the air inlet from high to low.
As an improvement, a flow distribution plate parallel to the flow guide plate is arranged above the flow guide plate positioned at the far end of the air inlet in the ash hopper. The ascending flue gas is guided in a shunting way through the shunting plate, and the flue gas is prevented from rotating to the near end of the air inlet after colliding with the side wall of the ash bucket.
As a further improvement, a transverse spoiler is arranged on one surface of the splitter plate facing the air inlet. So that the flue gas forms turbulent flow when rotating and is uniformly dispersed.
As another further improvement, the cross section of the spoiler is an isosceles right triangle.
As an improvement, the lower part of the deflector has a bend facing the air inlet. And plays a guiding role in flue gas.
As an improvement, the guide plate is connected with the ash bucket by means of a mounting plate.
As an improvement, the mounting plates are arranged in parallel. So that the installation is increased and stabilized.
As an improvement, the guide plate is made of a steel plate, so that the guide plate is more wear-resistant and the service life is prolonged.
The invention has the advantages that: the bag-type dust collector with the structure decelerates the smoke and uniformly distributes air through the guide plate and the flow distribution plate, the workload of each bag is balanced, the dust collection effect and the dust collection efficiency are greatly improved, and the economic benefit is increased for a factory by prolonging the service life of the bags.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
The labels in the figure are: 1 box body, 2 ash buckets, 3 cloth bags, 4 air inlets, 5 air outlets, 6 guide plates, 7 splitter plates, 8 spoilers, 9 mounting plates and 10 ash discharge valves.
Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the following embodiments.
As shown in FIG. 1, the invention comprises a box body 1 and an ash hopper 2 arranged below the box body 1; a plurality of cloth bags 3 are arranged in the box body 1, and an ash discharge valve 10 is arranged at the bottom of the ash bucket 2; the air inlet 4 is arranged on the ash bucket 2, and the air outlet 5 is arranged at the top of the box body 1; a plurality of guide plates 6 are arranged in the ash bucket 2 below the cloth bag 3; the guide plates 6 are vertically arranged and parallel to each other and are arranged along the extending direction vertical to the air inlet 5; and a plurality of guide plates 6 are arranged from near to far from the air inlet 5 in sequence from high to low. The lower part of the deflector 6 is provided with a bend facing the air inlet 5. The guide plate 6 is made of a steel plate, so that the guide plate is more wear-resistant and the service life is prolonged. The guide plate 6 is connected with the ash bucket 2 by means of a mounting plate 9. The mounting plates 9 are two parallel.
A flow distribution plate 7 parallel to the flow guide plate 6 is arranged above the flow guide plate 6 at the far end of the air inlet 4 in the ash bucket 2. And a transverse spoiler 8 is arranged on one surface of the splitter plate 7, which faces the air inlet 4. The cross section of the spoiler 8 is an isosceles right triangle.
When the converter is in work, converter flue gas enters the ash bucket 2 from the air inlet 4 and is decelerated and dispersed under the action of the guide plate 6. The flue gas of the far end of the air inlet 4 is divided by the dividing plate 7, one part of the flue gas directly rises, and the other part of the flue gas is blocked by the dividing plate 7 to rotate, so that the flue gas can be distributed to the far end of the air inlet 4, and the work load of each cloth bag 3 is balanced.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
