Packaging envelopes for urea solution

The present invention relates to a bag for packaging urea solution, and more particularly, the upper and lower gripping holes are provided at the upper and lower ends of the bag body, respectively, to facilitate the holding of the bag body and to stably inject the urea solution having fluidity. It relates to a packaging bag for urea aqueous solution to be made conveniently.

Recently, environmental pollution has become a major social issue, and even in the case of automobiles, electric, hydrogen, solar, and hybrid vehicles are actively developed and marketed as eco-friendly vehicles that do not use fossil fuels. It is true.

However, despite the emergence of such eco-friendly cars, automobiles that use gasoline or diesel as fuels still dominate the automobile market and are expected to remain in the market for a long time.

As such, in the case of an internal combustion engine vehicle using fossil fuels such as gasoline or diesel, there is a problem that environmental pollution due to exhaust gas is serious. Especially in diesel cars such as buses and trucks, the emission of soot, nitrogen oxides (NOx) and fine dust including soot is considered a serious problem.

Therefore, in order to solve the exhaust gas problem of diesel vehicles, each country has established a related regulation and strictly regulates the emission of exhaust gas.

As a method of treating the exhaust gas of the diesel engine as described above, an oxidation catalyst method, a NOx catalyst method, a diesel particulate filter (DPF) method for removing fine dust including soot is known.

Diesel engines operate in excess air in most areas, releasing large amounts of oxygen in the exhaust. Nitrogen oxide (NOx) reduction method based on the presence of oxygen includes a method of selectively decomposing nitrogen oxide (NOx) by using a selective catalytic reduction (SCR) catalyst coated with copper or iron ions and a reducing agent ammonia. .

In this SCR system, ammonia is generated using urea solution instead of reducing agent ammonia gas to selectively decompose nitrogen oxides (NOx), and for this purpose, the urea solution is stored in a storage tank. Urea solution is automatically supplied to the dosing unit in the required amount.

Diesel engine vehicles to which the above system is applied usually consume about 5% of the urea solution relative to the consumption of diesel fuel.

As described above, a diesel engine vehicle consumes urea solution separately from diesel fuel so as to decompose soot and nitrogen oxides (NOx), and the urea solution in a urea solution storage tank in which such urea solution is stored. It is injected and used periodically.

In this case, the urea solution is injected into the urea solution storage tank by using a urea solution packaging bag containing a certain amount of urea solution, for example, 10 liters, that is, connected to one side of the urea solution packaging bag.
