Abstract
The utility model provides a pipeline for improving the conveying concentration of pulverized coal, which consists of a main conveying pipe, an auxiliary conveying pipe and an air baffle plate; an auxiliary conveying pipe is arranged at the upper part in the main conveying pipe for conveying the pulverized coal, holes are formed in the auxiliary conveying pipe at intervals, and a gas baffle is arranged at the holes. The utility model discloses can improve buggy transport concentration, avoid the pipeline to block up, realize long distance transport to promote blast furnace buggy conveying capacity, reduce the conveying gas consumption, reduce the pipeline wearing and tearing.
Description
Technical Field
The utility model belongs to ironmaking pipe-line equipment field especially relates to a pipeline of concentration is carried to improvement buggy.
Background
The coal-increasing and coke-reducing ratio is required by increasing the proportion of coal powder injected into the blast furnace and reducing the coke ratio. In order to increase the conveying capacity of the coal powder, reduce the gas consumption and reduce the abrasion of the powder to equipment, the dense phase conveying gas pipeline is provided. Original defeated buggy pipeline is at long distance transport in-process, takes place to block up easily, need increase air supplement unit on the way, increases the gas consumption, and needs atmospheric pressure high, and pipeline wearing and tearing are fast.
Disclosure of Invention
The utility model aims at providing a can promote blast furnace buggy delivery volume, reduce the conveying gas consumption, reduce the pipeline of the improvement buggy transport concentration of pipeline wearing and tearing.
Therefore, the utility model discloses the technical solution who takes does:
a pipeline for improving the conveying concentration of pulverized coal comprises a main conveying pipe, an auxiliary conveying pipe and a choke plate; an auxiliary conveying pipe is arranged at the upper part in the main conveying pipe for conveying the pulverized coal, holes are formed in the auxiliary conveying pipe at intervals, and a gas baffle is arranged at the holes.
The utility model has the advantages that:
the utility model discloses can improve buggy transport concentration, avoid the pipeline to block up, realize long distance transport to promote blast furnace buggy conveying capacity, reduce the conveying gas consumption, reduce the pipeline wearing and tearing, prolong pipeline life.
Drawings

In the figure: main duct 1, sub-duct 2, choke plate 3.
Detailed Description
As shown in fig. 1, the pipeline for increasing the conveying concentration of pulverized coal of the present invention is composed of a main conveying pipe 1, an auxiliary conveying pipe 2 and a choke plate 3. An auxiliary conveying pipe 2 is arranged at the upper part in the main conveying pipe 1 for conveying the pulverized coal, holes are formed in the auxiliary conveying pipe 2 at intervals, and a gas baffle plate 3 is welded at the positions of the holes.
The main conveying pipe 1 and the auxiliary conveying pipe 2 do not distinguish gas and coal powder when the coal powder is conveyed, the gas baffle plate 3 is arranged at the opening of the auxiliary conveying pipe 2, when powder is conveyed in a pipeline, after a certain distance, the coal powder is deposited at the lower part of the main conveying pipe 1, at the moment, the gas is mainly in the auxiliary conveying pipe 2 at the upper part, when the gas passes through the opening, the gas baffle plate 3 generates airflow disturbance under the action of the gas baffle plate, the coal powder deposited at the lower part of the main conveying pipe 1 is taken up, and the conveying is continued. Therefore, the coal powder conveying concentration is improved, long-distance conveying can be realized, the pipeline is not blocked, and the coal powder concentrated phase reduces gas consumption and pipeline abrasion.
