Embodiment 1
[0054] See figure 2 , a storage tank 110 is provided, and an inlet 112 is opened on the side wall of the storage tank 110 near the bottom. The cross-section of the inlet 112 is circular. See image 3 , the diameter h1 of the circular inlet 112 is 25cm. The distance h2 between the inlet 112 and the bottom of the storage tank 110 is 25 cm.
[0055] The dilute lye (the mass fraction of sodium hydroxide in this embodiment is an aqueous solution of 2% to 5%) 120 is squeezed into the storage tank 110 until the liquid level of the dilute lye 120 is higher than the top of the inlet 112, such as image 3 As shown, the liquid level h3 of the dilute lye 120 is 60cm. Obviously, the liquid level of the dilute lye 120 is higher than the top of the inlet 112 .
[0056] Pass into dichloroethane 130 from import 112, obtain the storage device 100 of dichloroethane, as Figure 4 shown.

The invention relates to a dichloroethane storage method and device. The dichloroethane storage method uses a liquid sealing layer to seal dichloroethane, the liquid sealing layer is a hydroxide solution of an alkali metal, and the mass fraction of the hydroxide of the alkali metal in the hydroxide solution of the alkali metal is 2%-5%. In the dichloroethane storage method, the hydroxide solution of the alkali metal at the mass fraction of 2%-5% and dichloroethane are not mutually soluble, in addition, the density of the hydroxide solution of the alkali metal is lower than that of dichloroethane, the density of the hydroxide solution of the alkali metal and the density of the dichloroethane greatly differ from each other, therefore, the hydroxide solution of the alkali metal at the mass fraction of 2%-5%, as the liquid sealing layer of dichloroethane, plays an excellent role in sealing and isolating, so that the evaporation of dichloroethane is directly effectively avoided, and the hazards of dichloroethane on the environment and the body health of a staff are greatly reduced.
Description
technical field [0001] The invention relates to the technical field of storage of petroleum liquid chemicals, in particular to a storage method and a storage device for dichloroethane. Background technique [0002] Dichloroethane is a kind of halogenated hydrocarbon. Dichloroethane is a colorless liquid with a chloroform-like odor at room temperature. It is toxic and potentially carcinogenic. It is often used as a solvent and an intermediate for the manufacture of trichloroethane. And wax, fat, rubber and other solvents and grain pesticides. [0003] The traditional storage method of dichloroethane is to directly store dichloroethane in a storage tank, and store it in a sealed, cool and dry place away from light. However, this traditional storage method of dichloroethane is difficult to control the volatilization of dichloroethane, which is likely to cause certain harm to the environment and the health of the staff, which is not conducive to application.
