Description
Technical Field
The utility model relates to a converter steelmaking technical field especially relates to a converter blocks excessive device of smoke and dust with stokehold big intergate.
Background
During the production, iron adding, scrap steel adding and fettling periods and the like before a converter of a 2# line, a 7#8#9# converter of a certain steel-making main plant, smoke dust often overflows, particularly at the end of scheduled maintenance of the converter, due to the influence of the state of fan equipment, the smoke dust overflowing between the converter in front of the converter and a gate in front of the converter is serious, so that environmental pollution is caused, and the physical and mental health of workers is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a device that blocks excessive smoke and dust between converter and the stokehold gate solves between converter steelmaking gate and the converter that the smoke and dust is excessive, environmental protection and worker physical and mental health make steelmaking environmental protection more, environmental protection.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a device for blocking smoke dust from overflowing between a converter and a front gate comprises the converter, the front gate and a boiler, wherein the boiler is arranged above the converter, and the front gate is arranged on the side surfaces of the converter and the boiler; the spray pipe is arranged above the converter and on the inner side of a front gate of the converter, a plurality of nozzles are arranged on the spray pipe, the spray pipe is connected with a steam source through the guide pipe, and the control valve is installed on the guide pipe.
The nozzles are inclined downwardly by 15-20 deg..
Compared with the prior art, the beneficial effects of the utility model are that:
a device for blocking smoke dust overflow between a converter and a front gate of a converter solves the problem of smoke dust overflow between the front gate of the converter and the converter, protects the environment and physical and mental health of workers, makes steel making more environment-friendly and protects the environment.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-steam source, 2-guide pipe, 3-control valve, 4-spray pipe, 5-nozzle, 6-steam curtain, 7-furnace front gate, 8-converter, 9-boiler and 10-smoke dust.
Detailed Description
The following further describes the embodiments of the present invention:
referring to fig. 1, the device for blocking smoke dust overflow between a converter and a front gate comprises a converter 8, a front gate 7 and a boiler 9, wherein the boiler 9 is arranged above the converter 8, and the front gate 7 is arranged on the side surfaces of the converter 8 and the boiler 9; still include spray pipe 4, control valve 6, stand pipe 2, nozzle 5, spray pipe 4 sets up in the top of converter 8, the inboard of stokehold gate 7 be equipped with a plurality of nozzle 5 on spray pipe 4, spray pipe 4 passes through stand pipe 3 and connects steam source 1, control valve 3 is installed on stand pipe 2.
The nozzle 5 is inclined downwards R15-20 °.
The specific scheme is as follows:
a pipeline with the diameter of 57mm and the length of 5-7m is added above the space between a converter front gate 7 and a converter 8 to be used as a spray pipe 4, holes are formed in the spray pipe 4 at the distance of 25-30mm, then 197 nozzles with flat openings 1Cr18Ni9Ti are installed, and the angle R is inclined downwards to be 15-20 degrees. The converter steam with the self-production pressure of 1.5Mpa on the site of the converter is introduced into the spray pipe 4 through the guide pipe 2. A501G DN50 electric quick-cutting valve is added on the guide pipe 2 as a control valve 3.
The control valve 3 is opened during the production, iron adding, scrap steel adding and the like of the converter, a steam curtain 6 is formed in front of the converter 8 to prevent smoke dust from overflowing, and the smoke dust and steam of the smoke dust fall down simultaneously and are caught by a primary and secondary dust removing fan of the converter. Improve the capture of the smoke dust in front of the furnace and reduce the environmental pollution.
When the control valve 3 is used for production, steam enters the steam spraying pipe 4 arranged above the converter 8 from the guide pipe 2, and then the steam is sprayed between the converter 8 and the front gate 7 through the nozzle 5 to form a steam curtain, so that smoke dust overflows from the space between the front gate 7 and the converter 8 when the converter blows oxygen, adds iron and adds scrap steel, a steam isolation barrier is formed, the overflow control of the smoke dust in the front of the converter during steelmaking is realized, and the steelmaking is more environment-friendly.
