Aluminium triethyl storage tank and safety device thereof

Abstract

The invention relates to an aluminium triethyl storage tank and a safety device thereof, belongs to a storage tank of dangerous goods and particularly relates to a storage tank loading dangerous good liquid such as aluminium triethyl and the like and a sealing safety device thereof. The aluminium triethyl storage tank comprises a tank body, wherein a valve mounting part is arranged on an outlet part on the tank body; the valve mounting part is provided with a first valve and a second valve; the first valve is used for controlling the discharge and is communicated with an outlet connecting pipe; the second valve is used for controlling to charge and discharge protective gas; the inner cavity of the tank body forms a liquid-phase cavity part and a gas-phase cavity part; and the safety device for the storage tank is arranged on the valve mounting part. The safety device has the advantages of effectively preventing dangerous goods such as the aluminium triethyl liquid and the like from outflowing, effectively avoiding accidental leakage of the dangerous goods such as the aluminium triethyl liquid and the like because of carelessness such as misoperation and the like and fulfilling the aim of safe storage and transportation.

Description

technical field [0001] The invention belongs to dangerous goods storage tanks, in particular to a storage tank loaded with dangerous goods liquids such as triethylaluminum and a sealing safety device thereof. Background technique [0002] Triethylaluminum is a kind of alkyl metal, which has the characteristics of spontaneous combustion in air and reaction in water. Triethylaluminum is 4.2 / 4.3 in the classification of dangerous goods, and the United Nations dangerous goods number: UN3394. The "International Maritime Dangerous Goods Code" requires that storage tanks carrying such goods are not allowed to open at the bottom. Therefore, the existing storage tanks carrying such substances are all in the form of top openings. Image 6 As shown: the gas phase valve line 11 of the gas phase valve 1 is connected to the top of the tank and is located in the gas phase space after loading liquid, which is used to fill the tank with nitrogen and discharge nitrogen from the tank; the liqui...

AI Technical Summary

Problems solved by technology

[0003] The problem existing in the known technology is: during the storage and transportation of the storage tank, because the valve is prone to leakage, the triethylaluminum liquid will inevitably penetrate beyond the valve under the pressure of nitrogen, and a small amount of leakage will form at the outlet of the valve. Aluminum oxide, so it often occurs that such substances flow into the user system with the triethylaluminum liquid, resulting in the problem of blockage of the flowmeter

[0007] None of the known technologies can well solve the safety hazards of the aforementioned triethyl aluminum storage tanks during storage and transportation. Therefore, the industry urgently needs a kind of triethyl aluminum storage tank with a sealing device to come out.
