Description
Technical field
The present invention relates to agglomeration for iron mine technical fields, and in particular to one kind adds during iron ore sintering to charge level spray can
The security protection system of combustion property gas.
Background technique
On the surface of sinter bed, spray plus combustible gaseous fuel, yield rate and the rotary drum that sinter not only can be improved are strong
Degree reduces sintering solid burnup, can also reduce the discharge amount of carbon dioxide and sulfur dioxide, nitrogen oxides.However, to sintering
Contain a large amount of methane, hydrogen, carbon monoxide and hydrocarbon in the imflammable gas (such as: natural gas, coke-stove gas) that charge level spray adds
Class compound etc. is inflammable, explosive and toxic gas.Though methane and hydrogen have toxicity unlike carbon monoxide, in air
Middle content can make one to suffocate after reaching a certain level or even causing death.As fuel, methane and hydrogen can also be because exploding
And cause injures and deaths.Although the diverging lighter than air and easy of both gases, when they assemble in the enclosed environments such as house
In the case where when reaching certain ratio, the huge explosion of power will be triggered.
Therefore, in order to ensure imflammable gas occur escape, leakage, explosion, kindling etc. abnormal conditions when the person with set
Standby safety, it is necessary to a kind of spray of sintering charge level plus imflammable gas security protection system are designed, to realize in the sintering machine bed of material
Spray to surface safety aerating fluid fuel.
Summary of the invention
The technical problem to be solved by the present invention is to realize that a kind of sintering charge level spray adds imflammable gas security protection system,
System has comprehensively ensured the peace of the person and equipment when the abnormal conditions such as escape, leakage, explosion, kindling occur for imflammable gas
Entirely.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of spray of sintering charge level plus imflammable gas peace
Full protection system, burning branch pipe one end are connected to imflammable gas general pipeline, and other end jet port is towards sinter bed spray flammability
Gas forms fuel gas region, is successively arranged anti-poisoning alarm, flame detector and anti-escape upwards from the sinter bed
Escape alarm, and multiple anti-poisoning alarms constitute anti-poisoning alarm group around fuel gas edges of regions setting, more
A flame detecting alarm constitutes fire resistant detection alarm group around fuel gas edges of regions setting, multiple described
Anti- escape alarm constitutes anti-escape alarm group around fuel gas edges of regions setting.
The burning branch pipe is equipped with quick action emergency valve, each anti-poisoning alarm, flame detector and anti-escape
Alarm connects the input terminal of control system by signal wire, and the control system output end is promptly cut by signal wire connection
Disconnected valve.
When imflammable gas is natural gas, the anti-escape alarm and anti-poisoning alarm are methane alarm,
When imflammable gas is coke-stove gas, the anti-escape alarm is hydrogen alarm;When imflammable gas is blast furnace coal
When gas, the anti-escape alarm is carbon monoxide alarm.
When imflammable gas is natural gas, the anti-poisoning alarm is methane alarm;When imflammable gas is coke
When producer gas or blast furnace gas, the anti-poisoning alarm is carbon monoxide alarm.
Each anti-poisoning alarm is fixedly mounted at sinter bed 0.5~2m height
The detecting head of each flame detector is towards the jet port of burning branch pipe.
Means of defence based on the sintering charge level spray plus imflammable gas security protection system, each anti-poisoning alarm
The signal that will acquire in real time with anti-escape alarm is delivered to control system, when some anti-poisoning alarm or anti-escape alarm
When triggering alarm, while alarm signal is delivered to control system, then control system cuts off quick action emergency valve.
Flame detector obtains the signal whether jet port has flame in real time, judge imflammable gas whether occur kindling or
Detonation, when imflammable gas kindling or detonation situation occur for judgement, signal is delivered to control system by flame detector, then is controlled
System shutdown quick action emergency valve processed.
Phenomena such as present invention is by imflammable gas spray plus overlying regions escape, two sides leakage, internal explosion kindling
Omnibearing stereo monitoring, it is therefore prevented that imflammable gas situations such as a large amount of escapes, leakage and heavy explosion occurs and occurs, effectively
Personnel's poisoning, asphyxia, injures and deaths and the destruction to equipment, workshop are avoided, to solve on sintering charge level spray plus flammable
The security protection problem of property gas.
