Abstract
The utility model belongs to improvements of air supply systems of blast furnaces, in particular to an improved air supply system of the blast furnace. The improved air supply system of the blast furnace comprises air blowers evenly distributed and arranged in an air blowing operation area, wherein, an air supply pipe of each air blower directly supplies air to the corresponding blast furnace; an air conveying pipe for mutually communicating two parallel air supply pipes is arranged between parallel air supply pipes of every two adjacent air blowers; and a pneumatic control reversing valve is mounted on the air conveying pipe. The improved air supply system of the blast furnace has the advantages that the structure is reasonable; in the use process of the improved air supply system, in case of tripping due to fault or sudden stoppage of the air blowers during the operation of a unit, air can be automatically supplied to the blast furnace through adjacent parallel air supply pipes of the air blowers, so that the air supplied to the blast furnace is ceaseless, the damping-down time is shortened and the loss is reduced.
Description
Technical field
The utility model belongs to the improvement of blast furnace air feed system, particularly a kind of improved blast furnace air feed system.
Background technology
Thermoelectric subsidiary factory of the iron and steel enterprise first air blast working district, 9 typhoon machines are opened 5 and are equipped with 4, and original air feed pattern is air feed one to one; Corresponding to 5 blast furnace air feeds; In use, as breaking down jumping machine or when needing anxious blowing-out machine in the unit operation, the disconnected wind phenomenon of air feed blast furnace can take place; Can cause blast furnace to irritate the air port when serious, have a strong impact on blast furnace production direct motion.The analysis of causes: 380 blower fans are that electricity drags the formula gas blower, and blower fan air feed pattern is air feed one to one, need anxious blowing-out machine like unexpected outage or fan trouble, and air quantity, blast sharply descend, and the blast furnace air feed then can interrupt suddenly, causes the accident of the disconnected wind of blast furnace.
Summary of the invention
The purpose of the utility model is to provide a kind of improved blast furnace air feed system; It is rational in infrastructure, in the use, as breaking down jumping machine or when needing anxious blowing-out machine in the unit operation; Can blow to blast furnace automatically through its adjacent air feed pipe arranged side by side; Guarantee the continuous wind of blast furnace, shorten the damping down time, reduce the loss.
The purpose of the utility model is achieved in that a kind of improved blast furnace air feed system; Being included in the air blast working district is uniformly distributed with gas blower is being set; The air feed pipe of every gas blower is directly given corresponding blast furnace air feed; Between its air feed pipe arranged side by side of per two adjacent gas blowers, the wind conveying pipe that two air feed pipes arranged side by side are interconnected is being set, Pneumatic reversal valve is being installed on wind conveying pipe.
The utility model installs one group of Pneumatic reversal valve additional between the blast tube of adjacent air feed blast furnace, air feed just often is a closing condition, like jumping machine or the anxious blowing-out machine of need of breaking down in the unit operation; When causing air feed to interrupt, Pneumatic reversal valve can be opened automatically, changes a pair of two air feeds rapidly into by air feed one to one; Guarantee the continuous wind of blast furnace; Do not irritate the air port, greatly shorten the damping down time, reduce the loss.Effect: through improving, operational excellence is met when breaking down the jumping machine in the unit operation or needing anxious blowing-out machine, and disconnected wind and blast furnace filling air port phenomenon never take place.
The utility model is rational in infrastructure, in the use, as breaking down jumping machine or when needing anxious blowing-out machine in the unit operation, automatically to the blast furnace air-supply, has guaranteed the continuous wind of blast furnace through its adjacent air feed pipe arranged side by side, shortens the damping down time, has reduced loss.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below, accompanying drawing is the utility model structural representation.
Embodiment
A kind of improved blast furnace air feed system; Shown in accompanying drawing; Being included in the air blast working district is uniformly distributed with gas blower 1 is being set; The air feed pipe 2 of every gas blower is directly given corresponding blast furnace air feed, between per two adjacent gas blowers, 1 its air feed pipe 2 arranged side by side, the wind conveying pipe 3 that two air feed pipes 2 arranged side by side are interconnected is being set, and Pneumatic reversal valve 4 is installed on wind conveying pipe 3.Pneumatic reversal valve 4 is a double-piston pinion and-rack Pneumatic reversal valve.Manually stopping valve 5 is being set respectively on the wind conveying pipe 3 of Pneumatic reversal valve 4 both sides.In the process of blower unit operation, hand stop valve 5 is opened.
