Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a methanol storage tank and a methanol drying device thereof. Background Art

[0002] Methanol fuel is increasingly widely used in fields such as automobiles, generators, and gas stoves. Methanol is highly soluble in water. Excessive water in methanol fuel will cause a decrease in calorific value, and adding methanol with too high water content will have a serious impact on generator internal combustion engines and automobile engines. There is a breather valve provided on the existing methanol storage tank. When the pressure in the storage tank increases, the storage tank discharges gas through the breather valve. When the pressure in the storage tank decreases, air enters the storage tank through the breather valve. The air contains a large amount of moisture, and the entry of air into the storage tank will cause a serious decline in the purity of methanol.

[0003] Therefore, it is necessary to improve the existing methanol storage tank technically to avoid the problem of methanol being polluted by moisture in the air during the storage and use of methanol. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related technologies to some extent. For this reason, an object of the utility model is to provide a methanol storage tank and a methanol drying device thereof, which can filter moisture in the air in the methanol storage tank.

[0005] The technical solution adopted by the utility model is as follows:

[0006] In a first aspect, the utility model provides a methanol drying device for a methanol storage tank. The methanol storage tank includes a flame arrester breather valve and a double-layer explosion-proof storage tank containing methanol. The methanol drying device includes: a tank body disposed between the flame arrester breather valve and the double-layer explosion-proof storage tank, and the tank body is respectively communicated with the breather valve and the double-layer explosion-proof storage tank; wherein, molecular sieves are contained inside the tank body.

[0007] Wherein, a mesh bag is arranged inside the container of the tank body, and the molecular sieves are contained in the mesh bag.

[0008] Wherein, a quick-opening manhole is arranged on the tank body to quickly open the tank body to replace the molecular sieves.

[0011] Wherein, both the first pipeline and the second pipeline are made of steel pipes.

[0012] Among them, the first pipeline is vertically arranged, and the flame arrester breather valve is vertically arranged on the tank body.

[0013] In a second aspect, the present utility model provides a methanol storage tank, which includes: a flame arrester breather valve; a double-layer explosion-proof storage tank, in which methanol is contained inside the tank body of the double-layer explosion-proof storage tank; and the methanol drying device as described above.

[0014] The beneficial effects of the present utility model are:

[0015] By providing a methanol drying device on the existing methanol storage tank, the methanol drying device is respectively communicated with the flame arrester breather valve and the double-layer explosion-proof storage tank of the methanol storage tank. The main body of the methanol drying device is a small tank, and molecular sieves are arranged in the small tank.

The molecular sieve is put into the tank body 3 in a mesh bag for convenient overall removal. The molecular sieve will not flow out when the quick-opening manhole 36 is opened or closed.

[0023] Preferably, the tank body 31 is formed by welding steel plates.
