Problems solved by technology

[0003] Aiming at the lack of research and development of existing gas cabinets to prevent casualties and environmental pollution caused by gas leakage in gas cabinets, as well as the technical problems of emergency treatment after gas leakage, the present invention provides a double-hood semi-underground wet type that automatically handles leakage. A gas cabinet and a method for automatically treating leakage. The double-hood semi-underground wet gas cabinet that automatically handles leakage can not only automatically handle leaking gas in an emergency, but also prevent slightly water-soluble gas from being released to the external environment through the water in the water-sealed tank.

Embodiment 1

[0030] Embodiment 1: as figure 1 As shown, a double-hood semi-underground wet-type gas cabinet that automatically handles leakage includes a leak-proof cover 1, a bell jar 2, a breathing tube 3, a leakage gas treatment main pipe 4, an air inlet pipe 5, a water inlet / outlet pipe 6, an outlet pipe Gas pipe 7, liquid level gauge 8, flammable or toxic and harmful gas leakage detection and alarm device 9, water seal tank 10, floor tank 11, man access hole 14, interlock control connection line 15, induced draft fan 16, nitrogen pipe 18, industrial control machine,

[0031] A groove matching the water seal groove 10 is opened downward on the ground, and the water seal groove 10 is arranged in the groove, and the bell jar 2 is set upside down in the water seal groove 10, and the outer edge of the bottom surface of the bell jar 2 is in contact with the water seal groove. The inner wall of 10 fits together, the leak-proof cover 1 is reversed and arranged on the outside of the bell jar ...

Embodiment 2

[0040] Embodiment 2: The method for the automatic processing leakage of the double-hood semi-underground type wet gas holder adopts the double-hood semi-underground type wet type gas holder which automatically handles leakage, and the specific steps are as follows:

[0041] (1) When the flammable or toxic and harmful gases are slightly soluble in water, when the double-hood semi-underground wet gas cabinet is working, the flammable or toxic and harmful gases are stored in the bell jar, and the industrial computer controls the automatic breathing control on the breathing tube at the top of the leak-proof cover The valve is opened to maintain the air pressure balance between the leak-proof cover and the bell; the flammable or toxic and harmful gas leakage detection and alarm device installed in the leak-proof cavity formed by the leak-proof cover and the bell detects the concentration of flammable or toxic and harmful gases. Concentration C of flammable or toxic and harmful gases...

Embodiment 3

[0044] Embodiment 3: Use the double-hood semi-underground wet-type gas cabinet that automatically handles leakage in Embodiment 1 to store vinyl chloride. Vinyl chloride is flammable and toxic. The specific gravity of vinyl chloride is larger than that of air and slightly soluble in water; flammable or toxic and harmful gases The leak detection and alarm device is installed at the bottom of the leak-proof cavity formed by the leak-proof cover and the bell jar and the lower part of the trough;

[0045] In the normal production process, vinyl chloride gas enters the bell-type gas cabinet through the inlet pipe through the water-sealed tank, and then exits the gas cabinet through the outlet pipe. The breathing tube maintains the air pressure balance between the double covers and the external environment; there are 12 sets of stable blocks at the bottom of the bell, which can keep the bell stable during the up and down movement of the bell, and 12 sets are set corresponding to the ...

Abstract

The invention relates to a double-cover semi-underground wet-type gas cabinet capable of automatically treating leakage and a method for automatically treating leakage, and belongs to the technical field of safety of chemical production equipment. The double-cover semi-underground wet-type gas cabinet capable of automatically treating leakage comprises a leakage-proof cover, a bell cover, a breathing pipe, a leakage gas treating main pipe, an air inlet pipe, a water inlet / outlet pipe, an air outlet pipe, a liquid level meter, a combustible or toxic and harmful gas leakage detection alarm, a water seal groove, a trough, a manhole, an interlocking control connecting wire, an induced draft fan, a nitrogen pipe and an industrial personal computer. According to the double-cover semi-undergroundwet-type gas cabinet capable of automatically treating leakage and the method for automatically treating leakage, combustible or toxic harmful gases can be safely and reliably stored in the chemicalproduction process and can be prevented from entering the environment to cause safe production accidents and environmental pollution problems due to leakage, and early warning and emergency treatmentafter gas leakage can be made in time.

Description

technical field [0001] The invention relates to a double-hood semi-underground wet gas cabinet for automatic leakage treatment and a method for automatic treatment of leakage, belonging to the technical field of chemical production equipment safety. Background technique [0002] In recent years, my country has made some new technological progress in the research of gas cabinet equipment technology. A wet-type gas holder with automatic pressure regulation in the prior art can automatically adjust the pressure of the bell jar and the water body, reduce damage to the gas holder, and prolong the service life of the gas holder. A wet-type acetylene gas holder is characterized in that the internal water volume of the gas holder is small, the gas storage space is large, and the water circulation is updated rapidly. The utility model relates to an inner rod type stainless steel gas holder, the purpose of which is to reduce the cost of the gas holder and increase the service life. ...
