Abstract
The utility model relates to a leakage energy cabinet for a gas bottle and in particular relates to a small leakage emergency cabinet for a gas bottle, which is used in case of emergency when the gas bottle containing hazardous gases such as highly toxic gases, inflammable gases or highly corrosive gases are leaked. The small leakage emergency cabinet comprises a cabinet body, wherein a cabinet door is arranged on the cabinet body; when the gas bottle has leakage, the gas bottle is transferred to the emergency cabinet, and the cabinet door and the cabinet body are fastened together by a bolt; if the leaked gas is inflammable gas or explosive gas or the leaked gas is on fire, a fire sprinkler is opened to cool the bottle body and drain water timely for the emergency cabinet; when the gas in the gas bottle is leaked completely, the gas bottle is taken out by opening the cabinet door. The small leakage emergency cabinet is simple in structure, low in manufacturing cost, convenient to operate, easy to clear and good in gas tightness; moreover, complete environment-friendly treatment can be carried out on the leaked gas without secondary pollution.
Description
Technical field
The utility model relates to a kind of gas cylinder and reveals emergent cabinet, and the small gas cylinder that relates in particular to a kind of gas cylinder emergency under leakage situation for hazardous gases such as hypertoxic, inflammable or severe corrosives leaks emergent cabinet.
Background technique
At present, in the solar cell industry of semiconductor, microelectronic industry and rapid growth in recent years, the less special gas of processing procedure specific consumption mostly fills in the steel cylinder of 40-50L.Because a lot of special gases have even hypertoxicity of corrosivity, flammability, toxicity.This just to steel cylinder use and storing process in sealability require that very high (for example: borine, its MPC value in workshop air is 5 * 10
﹣ 8)
.for gas cylinder, the situation that may occur to leak mainly contains: 1, in cylinder valve, leakage conductance causes and can't thoroughly close; 2, the cylinder valve barrier film, because stress fatigue generation slight crack occurs long-term the use, causes valve rod gas leakage; 3, the valve footpath fractures because of collision; 4, cylinder valve and bottle diameter connecting thread place poor sealing cause gas leakage; 5, bottle break (occurrence probability minimum).Some hazard of gas is high, and very little leakage rate just may cause serious loss.As: suck 2.5 * 10
﹣ 4the arsine gas of concentration can make the people poisoning lethal immediately.The full bottle of gas filling pressure is generally between 70～120kgf/cm2, once gas cylinder leaks, because pressure of the inside of a bottle is very high, by the method for shutoff leakage point, processing is impracticable substantially.At present both at home and abroad for this situation emergent, mainly contain two kinds of methods: 1, gas cylinder is transferred to a spaciousness, unmanned place, let alone to leak.This method security is poor, and suitable place is not easy to look for, and is eliminated gradually.2, use
eRCV(External Reactor Vessel Cooling), domestic being commonly called as " iron coffin ".
eRCVbe a kind of removable, column Pressure Container that antiknock quality are strong, only in European and American areas, several companies produce at present.Will during Emergency use
eRCVone end is opened, and will leak the gas cylinder plug to the inside, more locked cap seal.The ERCV the other end has valve and pressure gauge, when container inner pressure is higher, outlet is caused to the open flame source place, opens valve the residual gas of leakage is burnt.
eRCVgood impact resistance, even if gas cylinder section's blast within it can not broken yet, Security is also very high.But there is following shortcoming in it: 1. in container, having part leakage residual gas can not thoroughly discharge; While 2. discharging, the gas by product that produces (may toxic or corrosivity) that may burn not to the utmost and burn can cause secondary pollution (or harm); 3. because turbidity test in container are too poor, particle is more, can affect like this tightness generation secondary leakage phenomenon of ERCV membrane valve; 4. expensive: one
eRCVprice general charged does not wait 6～90,000.
The model utility content
The deficiency that the purpose of this utility model, at the gas cylinder that overcomes hazardous gases such as having hypertoxic, inflammable or severe corrosive now, emergence technology occurs to leak, and provide a kind of small gas cylinder to reveal emergent cabinet, this device is a kind of certain antiknock ability that has, and supporting the cabinet of taking out pressure pipeline and fire-fighting spraying function arranged, low, the easy cleaning of fabricating cost, tightness are good, and can carry out thorough environmental protection treatment to the gas leaked out, can not cause secondary pollution.
The technological scheme that the utility model adopts:
A kind of small gas cylinder is revealed emergent cabinet, comprises cabinet, is arranged on the cabinet door on cabinet, and it is characterized in that: cabinet is the cuboid cabinet be welded with argon arc welding, on a side of cabinet, the cabinet door is installed.
The high scope of the length and width of described cabinet is respectively 400-600mm, 300-400mm, 1500-1800mm, and being welded its material therefor is stainless-steel sheet.
Be welded with the many stiffeners that are parallel to each other or intersect on cabinet outer surface and cabinet door.
On the cabinet at cabinet door place, Stamping Steel Ribbon is installed.
Position corresponding on cabinet door and cabinet respectively has fastening screw.
Gas-cylinder retaining assembly is installed in cabinet and is with valvular column fire-fighting spray device; At the top of cabinet, the negative-pressure pipeline with valve is installed, the sampling arm with valve is installed below the valve of negative-pressure pipeline; In the bottom of cabinet, the waste pipe with valve is installed.
The valve of described column fire-fighting spray device is in the outside of cabinet.
The beneficial effects of the utility model: simple in structure, fabricating cost is low, easy to operate, easy cleaning, tightness are good, and can carry out thorough environmental protection treatment to the gas leaked out, can not cause secondary pollution.

Embodiment
As shown in Figure 1, 2, 3, a kind of small gas cylinder is revealed emergent cabinet, comprises cabinet 1, is arranged on the cabinet door 2 on cabinet 1, and cabinet 1 is the cuboid cabinet be welded with argon arc welding.
High 400-600mm, 300-400mm, the 1500-1800mm of being respectively of the length and width of described cabinet 1, being welded its material therefor is stainless-steel sheet.
Be welded with the many stiffeners that are parallel to each other or intersect 7 on cabinet 1 outer surface and cabinet door 2.
On the cabinet 1 at cabinet door 2 places, Stamping Steel Ribbon 9 is installed.
On cabinet door 2 and cabinet 1, corresponding position respectively has fastening screw 8.
Gas-cylinder retaining assembly 3 is installed in cabinet 1 and is with valvular column fire-fighting spray device 4; Negative-pressure pipeline 5 with valve is installed at the top of cabinet 1, the sampling arm 6 with valve is installed below the valve of negative-pressure pipeline 5; Waste pipe 10 with valve is installed in the bottom of cabinet 1.
The valve of described column fire-fighting spray device 4 is in the outside of cabinet 1.
After gas cylinder leaks, the emergency worker transfers to gas cylinder in cabinet 1 and gas cylinder is fixed on gas-cylinder retaining assembly 3, if leakage rate is very little, can suitably open cylinder valve, export a release of accelerating gas in bottle by gas cylinder, close that cabinet door 2 is rear to tighten together cabinet door 2 and cabinet 1 with bolt.If the gas leaked is that inflammable and explosive character or gas catch fire, open fire-fighting spray device 4, bottle is lowered the temperature; After opening fire-fighting spray device 4, need the interior timing drainage of cabinet 1, the harmful gas in cabinet 1 flows to factory's business waste gas treatment equipments such as burning machine, soda acid spray and disposes through negative-pressure pipeline 5.In order to check in gas cylinder, whether gas leaks fully, and the valve open by the sampling arm 6 on negative-pressure pipeline 5, carry out sample detecting to gas in cabinet, by the analysis to gas concentration, judges in gas cylinder, whether gas leaks complete.
