Description

Technical Field

[0001] The utility model relates to the technical field of urea barrel packaging, in particular to a diesel exhaust treatment liquid storage tank. Background Art

[0002] Diesel exhaust treatment fluid is a highly refined chemical product. Metal ions such as aluminum, calcium, iron, copper and other organic substances must not be added during storage and transportation, otherwise the treatment effect of vehicle exhaust will be greatly reduced. At present, the container used to store diesel exhaust treatment fluid adopts stainless steel tanks, and retail can only use 10L / barrel and 20L / barrel stainless steel barrels in the form of barrels. However, these stainless steel tanks or barrels are welded by stainless steel plates. The welds of the tanks or barrels will produce intergranular corrosion and liquid leakage during long-term use; therefore, stainless steel tanks or barrels have the defect of short life and will also pose a major accident hazard. In addition, if this solution is stored above 25°C, the shelf life will be greatly shortened, and the thermal insulation performance of stainless steel materials is extremely poor, which is not suitable for the storage of diesel exhaust treatment fluid.
