Abstract
The invention provides a method for preventing converter smoke dust from polluting environment, which comprises the steps of respectively combining the radius of 1/4 of the front of a converter and the radius of the rest 3/4 of the converter into a group, arranging at least 4 water mist nozzles at the periphery of a converter mouth, arranging an abnormal smoke dust purification button for controlling the blowing process of all the water mist nozzles in a main control room, arranging a hot metal charging furnace gas purification button for controlling the 1/4 water mist nozzles in the front of the converter in a hot metal charging room, and arranging a steel tapping smoke dust purification button for controlling the rest 3/4 water mist nozzles in a steel tapping operation console. Starting a gas purification button of the iron charging furnace during iron charging; starting an abnormal smoke purification button in the blowing process when splashing is about to occur or already occurs in the smelting process; when the first half steel of the duplex converter is tapped, a tapping smoke purification button or an abnormal smoke purification button in the blowing process is opened. The invention can effectively inhibit and purify the converter smoke dust, greatly reduce the pollution of harmful smoke dust to the air inside and outside the plant and the environment, improve the production working environment and the air quality, and ensure the health of workers and nearby residents.
Description
Technical field
The invention belongs to make steel environmental protection technical field more particularly to one kind to prevent converter iron making from spilling iron, blowing splash
Or in preceding half steel tapping process dust polluting environment method.
Background technology
Converter unavoidably has partial molten iron scraping collision fire door in iron making, to generate volume of smoke gas.Meanwhile turning
It is various physics, a chemical reaction process acutely carried out in stove converting process, in converter, if do not reacted these
Particularly effective control is carried out, then will appear excessive clinker or even splash, the quick-fried phenomenon of spray, converter in addition is one continuous big raw
Container is produced, the splash of converting process quick-fried with spray is substantially to avoid completely.And once occur splash and spray it is quick-fried, due to
Gas discharge amount is far longer than the dust collection capacity of petticoat pipe, and outside also generates volume of smoke so that is shrouded completely in workshop
In flue dust.When the preceding half steel tapping steel that in addition converter duplex is smelted, carbon content when due to tapping is high, and Sheng steel used
Container is also hot-metal bottle, due to the effect of residual oxygen in steel, necessarily will produce the red cigarette based on a large amount of FeO particles.
The flue dust that converter generates in above process is mainly made of various small iron filings and FeO particles etc., these
Harmful substance is inhaled into vivo, very serious to the body harm of people, is worked in such a case for a long time, is suffered from silicosis disease
Probability is very big, and the fume amount generated when iron making sometimes is excessive, is exactly outside workshop it can be seen that billowing black smoke, this is to surrounding
The air of extensive area is also a kind of very serious pollution, or even can promote the formation of near zone haze weather.
Invention content
The present invention provides a kind of method preventing converter dust pollution environment, and purpose is intended to inhibit and purify converter cigarette
Dirt reduces pollution of the noxious fume to factory's inner air and outer air, improves production work environment and air quality.
For this purpose, the technical solution that the present invention is taken is:
A method of prevent converter dust from polluting environment, specific method is:
(1) at least four hydraulic spray nozzle, hydraulic spray nozzle horizontal direction distance converter movable is arranged in surrounding on converter mouth
Petticoat pipe outer distance >=0.5m, hydraulic spray nozzle extreme lower position are above lower edge when reaching limes superiors position away from converter movable hood
At 0.8~1.2 meter;
(2) hydraulic spray nozzle is divided into two groups, and 1/4 radius is one group before Converter, remaining 3/4 radius is one group;
(3) switch of hydraulic spray nozzle uses remote control, the converting process of the whole hydraulic spray nozzles of master control room setting control different
Normal clarifying smoke button, the iron making flue gas cleaning button of stokehold iron making room setting control 1/4 hydraulic spray nozzle of stokehold, tapping steel platform
The tapping clarifying smoke button for controlling remaining 3/4 hydraulic spray nozzle is set;
(4) hydraulic spray nozzle flow is reached the annulus area at fire door and can be covered around fire door with the atomized water sprayed is
Standard, and away from fire door outer >=2m;
(5) when stokehold iron making, start iron making flue gas cleaning button, carry out the atomizing of iron making flue dust, iron making is completed
Iron making flue gas cleaning button is closed afterwards;
(6) when to occur splash in smelting process or have begun splash, start converting process exception flue dust at once
Button is purified, the disperse everywhere of flue dust is inhibited;When splash terminates or after because of splash blunderbuss, it is net to close converting process exception flue dust
Change button;
(7) it while the preceding half steel tapping steel smelted in converter duplex starts, opens tapping clarifying smoke button or blows
Process exception clarifying smoke button is refined, tapping terminates to close tapping clarifying smoke button or converting process exception clarifying smoke is pressed
Button.
Beneficial effects of the present invention are:
The present invention can effectively inhibit and purify converter dust, greatly reduce noxious fume to the inside and outside air of factory and environment
Pollution improves production work environment and air quality, ensures the living environment of the health and neighbouring resident of worker, be conducive to
Realize the green production of heavy industry enterprise.
It is not any to high temperature liquid iron or molten steel since the water that the water mist that hydraulic spray nozzle of the present invention sprays generates is smaller
It influences, therefore any security risk will not be caused for converter smelting.
Specific implementation mode
By taking 260 tons of top and bottom combined blown converters as an example, hydraulic spray nozzle using conticaster hydraulic spray nozzle.
1, surrounding is uniformly arranged 8 hydraulic spray nozzles on converter mouth.Hydraulic spray nozzle horizontal direction distance converter movable
Petticoat pipe outer diameter is more than or equal to 1m, and short transverse reaches the lower 1 meter above position of limes superiors away from converter movable hood.
2, hydraulic spray nozzle is divided into two groups, and 1/4 radius of stokehold is one group, remaining 3/4 radius is one group.
3, the switch of hydraulic spray nozzle is remote control, at master control room one, at stokehold iron making houselet one, and tapping steel platform one
Place.
4, hydraulic spray nozzle flow, which is subject to the annulus area that the atomized water that sprays reaches at fire door, to cover around fire door,
Atomized water is away from fire door outer 2.3m.
5, when stokehold iron making, start iron making flue gas cleaning button, flue gas cleaning button is closed after the completion of iron making.
6, when smelting process discovery splash will occurs or have begun splash, it is net to start converting process exception flue dust at once
Change button, when splash terminates or after because of splash blunderbuss, closes converting process exception clarifying smoke button.
7, while the preceding half steel tapping steel smelted in converter duplex starts, tapping clarifying smoke button, tapping are opened
Terminate to close tapping clarifying smoke button.Certainly, it while the preceding half steel tapping steel smelted in converter duplex starts, can also open
Converting process exception clarifying smoke button is opened, same effect can also be reached by enabling whole nozzles.
