Description

A kind of spray of sintering charge level plus imflammable gas security protection system and its method
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.
Detailed description of the invention
Below to width attached drawing every in description of the invention expression content and figure in label be briefly described:
