Abstract
The invention provides a method for preventing smoke of a converter from polluting the environment. The method comprises the following steps: arranging at least four spray nozzles on the periphery of a fire hole and dividing the spray nozzles into two groups, wherein one group of the spray nozzles are positioned at the 1/4 radius in the front of the converter while the other group of the spray nozzles are positioned at the rest 3/4 radius; arranging a blowing process abnormal smoke purifying button for controlling all the spray nozzles on a master control chamber; arranging an iron charging furnace gas purifying button which controls the 1/4 spray nozzles in the front of the converter on an iron charging room in the front of the converter; arranging a steel tapping smoke purifying button which controls the rest 3/4 spray nozzles on a steel tapping operation table; starting the iron charging furnace gas purifying button during iron charging; starting the blowing process abnormal smoke purifying button when splashing is about to be caused or has been caused in a smelting process; and starting the steel tapping smoke purifying button or the blowing process abnormal smoke purifying button during tapping of duplex front half steel of the converter. By the method, converter smoke can be effectively suppressed and purified, pollution of harmful smoke to the air and the environment of the inside and the outside of a factory is reduced greatly, the production and working environment and the air quality are improved, and health of staff and nearby residents is guaranteed.
Description
Technical field
The invention belongs to make steel environmental protection technical field, more particularly to one kind prevents converter iron making from spilling iron, blowing splash or first half
The method of dust polluting environment in steel tapping process.
Background technology
Converter has partial molten iron scratching fire door in iron making, unavoidably, so as to produce volume of smoke gas.Meanwhile, converter is blown
It is various physics, a chemical reaction process for acutely carrying out during refining, in converter, if do not carried out to these reactions
Particularly effective control, then occur excessive slag or even splash, spray quick-fried phenomenon, and converter in addition is that a continuous big production is held
Device, the splash of converting process is quick-fried with spray can not possibly substantially to be avoided completely.And splash once occurs and sprays quick-fried, due to gas
Discharge rate is far longer than the dust collection capacity of petticoat pipe, and outside also produces volume of smoke so that shrouded in flue dust completely in factory building.
During the preceding half steel tapping steel that other converter duplex is smelted, because the melted steel container high and used of carbon content when tapping is also
Hot-metal bottle, due to the effect of residual oxygen in steel, will necessarily produce the red cigarette based on substantial amounts of FeO particles.
The flue dust that converter is produced in above process is mainly and is made up of various small iron filings and ferric oxide particles etc., and these are harmful to
Material is inhaled into vivo, and the body harm to people is very serious, works in such a case for a long time, suffers from the probability of silicosis disease
Very big, the fume amount for being produced during iron making sometimes is excessive, is exactly outer in factory building it can be seen that the black smoke for billowing, this is to big model around
The air for enclosing region is also a kind of very serious pollution, or even the formation that can promote near zone haze weather.
The content of the invention
The present invention provides a kind of method for preventing converter dust from polluting environment, and its purpose is intended to suppress and purify converter dust, reduces
Pollution of the noxious fume to factory's inner air and outer air, improves production work environment and air quality.
Therefore, the technical solution that the present invention is taken is：
A kind of method for preventing converter dust from polluting environment, its specific method is：
(1) surrounding sets at least 4 hydraulic spray nozzles, hydraulic spray nozzle horizontal direction distance converter movable hood on converter mouth
Outer distance >=0.5m, the lower edge top 0.8~1.2 when hydraulic spray nozzle extreme lower position is away from converter movable hood arrival limes superiors position
At rice；
(2) hydraulic spray nozzle is divided into two groups, and 1/4 radius is one group before Converter, and remaining 3/4 radius is one group；
(3) switch of hydraulic spray nozzle uses remote control, master control room to set the converting process exception flue dust of the whole hydraulic spray nozzles of control
Purification button, stokehold iron making room sets the iron making flue gas cleaning button of the control hydraulic spray nozzle of stokehold 1/4, and tapping steel platform sets control
The tapping clarifying smoke button of remaining 3/4 hydraulic spray nozzle；
(4) hydraulic spray nozzle flow can be covered around fire door by the annulus area that the atomized water for spraying is reached at fire door and is defined, 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, closed after the completion of iron making
Close iron making flue gas cleaning button；
(6) when to occur splash in smelting process or have begun to splash, converting process exception clarifying smoke is started at once and is pressed
Button, suppresses the disperse everywhere of flue dust；Terminate when splash or after because of splash blunderbuss, close converting process exception clarifying smoke button；
(7) while the preceding half steel tapping steel smelted in converter duplex starts, tapping clarifying smoke button or converting process are opened
Abnormal clarifying smoke button, tapping terminates to close tapping clarifying smoke button or converting process exception clarifying smoke button.
Beneficial effects of the present invention are：
The present invention can effectively suppress and purify converter dust, greatly reduce pollution of the noxious fume to the inside and outside air of factory and environment,
Improve production work environment and air quality, it is ensured that the living environment of the healthy and neighbouring resident of worker, be advantageously implemented weight
The green production of industrial enterprise.
Because the water that the water smoke that hydraulic spray nozzle of the present invention sprays is produced is smaller, there is no any influence to high temperature liquid iron or molten steel,
Therefore any potential safety hazard is not resulted in for converter smelting.
Specific embodiment
By taking 260 tons of top and bottom combined blown converters as an example, hydraulic spray nozzle using conticaster hydraulic spray nozzle.
1st, surrounding is uniformly arranged 8 hydraulic spray nozzles on converter mouth.Outside hydraulic spray nozzle horizontal direction distance converter movable hood
Footpath is more than or equal to 1m, and short transverse reaches the lower along 1 meter above position of limes superiors away from converter movable hood.
2nd, hydraulic spray nozzle is divided into two groups, and the radius of stokehold 1/4 is one group, and remaining 3/4 radius is one group.
3rd, the switch of hydraulic spray nozzle is remote control, at master control room one, at stokehold iron making houselet one, at tapping steel platform one.
4th, hydraulic spray nozzle flow can be covered around fire door by the annulus area that the atomized water for spraying is reached at fire door and is defined, atomized water
Away from fire door outer 2.3m.
5th, when stokehold iron making, start iron making flue gas cleaning button, flue gas cleaning button is closed after the completion of iron making.
6th, when smelting process finds splash occur or have begun to splash, converting process exception clarifying smoke button is started at once,
Terminate when splash or after because of splash blunderbuss, close converting process exception clarifying smoke button.
7th, while the preceding half steel tapping steel smelted in converter duplex starts, tapping clarifying smoke button is opened, tapping terminates to close
Close tapping clarifying smoke button.Certainly, while the preceding half steel tapping steel smelted in converter duplex starts, blowing can also be opened
Process exception clarifying smoke button, enabling whole nozzles can also reach same effect.
