Description

Technical Field

[0001] The utility model belongs to the technical field of urea production, and in particular relates to a storage device for urea production with an adsorption structure. Background Art

[0002] Automotive urea is an essential additive for the SCR solution. Heavy trucks, buses and other diesel vehicles need to meet the National IV emission standards, and they need to use a suitable SCR system for exhaust gas treatment. This system must use urea solution to treat nitrogen oxides in the exhaust gas. Therefore, automotive urea solution has become a necessary product for heavy trucks and buses to meet the National IV emission standards.

[0003] After the production of automotive urea is completed, it needs to be stored. An activated carbon layer is generally provided on the top of the exhaust pipe of the storage tank. The activated carbon is used to filter and adsorb the exhaust gas to reduce the damage to personnel and the pollution to the environment caused by the exhaust gas.

[0004] In view of the existing patent CN202222815500.3, a storage device for the production of automotive urea is disclosed. The device has a slide groove, a lifting block, a fixing rod, a push-pull rod, a plug rod, a plug hole, a fixing plate, a positioning screw and a positioning hole arranged in the exhaust pipe. When the activated carbon adsorption mesh plate has been used for a period of time, it is convenient to take out the activated carbon adsorption mesh plate from the exhaust pipe, so as to facilitate the replacement of a new activated carbon adsorption mesh plate. The technical problem that when the working state of the activated carbon layer is affected after being used for a period of time, it is not convenient to take out the activated carbon layer for replacement, resulting in poor gas filtration effect during the exhaust process is solved. However, the device adopts bolts to replace the activated carbon adsorption mesh plate. Although the method of screwing the bolts can achieve the purpose of fixing, tools are required for installation and disassembly, which is relatively troublesome. At the same time, when the screws are used for a long time, they are not only prone to rust due to the influence of the external environment, but also prone to thread slippage, which makes disassembly difficult. Further improvement is needed. Utility Model Content
