Good fuel gas gas cabinet.
Background technique
In existing laboratory fuel gas gas cabinet, laboratory fuel gas gas cabinet is only simple to fix fuel gas
The effect of bottle and alarm.Laboratory often uses fuel gas, so combustion gas bottle cabinet is in the application in laboratory
It is very common.Many fuel gas are colorless and odorless, laboratory will not 24 hours Attended modes, the leakage of fuel gas is non-
Often with there is concealment.Inflammable organic solvent is often used in laboratory, and high-temperature heating is often used in laboratory,
Even directly use open fire.Laboratory in operation, such as in order to guarantee the accurate of weighing result when being weighed with precision balance
Property, it is necessary to make to keep certain air-tightness in laboratory.These all make laboratory fire-fighting work become cumbersome and arduous, experiment
The fire-fighting prevention work of room just seems more important.The gas cabinet danger source great as laboratory, it is necessary to guarantee it
Higher safety, in addition laboratory fuel gas property density etc. is had nothing in common with each other, traditional laboratory gas cabinet is difficult to have a full house
Laboratory safety requirements of one's work.Therefore, it is necessary to use safer laboratory fuel gas gas cabinet.
Summary of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, provide a kind of safer novel reality
Room fuel gas gas cabinet is tested, which re-mounts multiple combustible gas detectings according to fuel gas and comparing for air
Device convenient for the leak case of the fuel gas of detection different densities, and combines exhaust system, alarm system and fire protection control room
It realizes intelligence and artificial monitoring, it is avoided leakage explosion accident occur.
Technical solution provided by the utility model: the novel laboratory fuel gas gas cabinet of described one kind, including cabinet body
And cabinet door, it is characterised in that: the top plate of the cabinet body uses lightweight single layer top plate, is equipped with exhaust system, air-supply system on the cabinet
System, controller and alarm are equipped with multiple combustible gas probes, the multiple combustible gas probe dispersion in cabinet body
The position of cabinet body internal upper part, middle part and lower part different height is set；The signal output end of the multiple combustible gas probe
Connect respectively with the signal input part of controller, the signal output end of controller respectively with exhaust system, supply air system and alarm
The signal input part of device connects.
The present invention preferably technical solution: the mounting height of the multiple combustible gas probe in cabinet body according to placing
The opposite specific gravity of different fuel gas and air determines.
The present invention preferably technical solution: be additionally provided on the cabinet for at fire protection control room or 24 hours Attended modes
Fire alarm control unit detection circuit interface.
The present invention preferably technical solution: the rear side of cabinet body is arranged in the controller and alarm.
The present invention preferably technical solution: the air inlet of the exhaust system and the row for opening up the cabinet body wherein lower section of side
Air port connection, the air outlet of supply air system are connected to the air inlet being provided with above the cabinet body other side；In exhaust system and air-supply
In opposite barotropic state in cabinet body under the action of system.
The utility model is pacified in gas cylinder upper part in cabinet, middle part, lower part according to the reselection procedure that compares of fuel gas and air
The different detector of holding position, fuel gas smaller than atmospheric density in this way can be detected by the detector on top at first, close
Degree and the comparable fuel gas of air may be mounted to that the detector on middle part or top detects, and gas density is bigger than air
Fuel gas can be detected by the detector of lower part.Detection be ensure that without dead angle while ensure that there is leakage in fuel gas
When, it is detected at the first time.
To reduce gas cabinet explosion energy, gas cabinet cabinet top uses lightweight top plate, while opening pressure relief opening in cabinet body side, most
The reduction explosion bring of limits is destroyed.Access supply air system and exhaust system, usually make to be in gas cabinet in gas cabinet
Opposite barotropic state prevents fuel gas because of leakage aggregation.Combustible gas probe and air supplying and exhausting system linkage, arrive combustible gas
When body lower explosion limit 25%, accelerating air supplying and exhausting system makes Gas scavenging number in cabinet reach at least 12 beats/min.Fuel gas is visited
Examining system is not only being equipped with sound-light alarm on gas cabinet, while accessing at fire protection control room or 24 hours Attended modes, gas cylinder
There are abnormal conditions in cabinet, occurs being different from miscellaneous cause alarm audible and visible alarm, system records laboratory position where gas cabinet, gas
Body leak time, concentration etc., convenient for investigation in time.
The utility model accesses combustible gas probe and air supplying and exhausting system linkage, when combustable gas concentration reaches its explosion
When lower limit 25%, combustible gas probe and air supplying and exhausting system linkage make Gas scavenging number in cabinet reach at least 12 beats/min,
Leakage fuel gas is discharged quickly.It generally will not 24 hours Attended modes in view of laboratory.Fuel gas in gas cabinet is visited
Device is surveyed when receiving alarm signal, signal is passed to alarm controller for combustible gas base, will be reported by alarm controller for combustible gas base
In the detection circuit of the fire alarm control unit of the alert incoming building of signal.And sound-light alarm is not only equipped on gas cabinet,
It accesses at fire protection control room or 24 hours Attended modes, when also thering is gas cabinet abnormal conditions occur, occurs being different from miscellaneous cause
Alarm audible and visible alarm, system record laboratory position where gas cabinet, gas leak time, concentration etc., convenient for checking in time.
This practical the fastest leakage for detecting fuel gas of energy, and discharge fuel gas at the first time, release peace
Full hidden danger.Even if laboratory nobody when can guarantee laboratory because combustible gas leakage and caused by safety accident.
