Description

Technical Field

[0001] The utility model relates to the technical field of tail gas recovery, in particular to a urea tail gas recovery and utilization device. Background Art

[0002] Exhaust gas mostly refers to automobile exhaust gas, that is, the waste gas discharged from the exhaust pipe of the car. Automobile exhaust gas is another major factor of air pollution. Automobile exhaust gas contains carbon monoxide, nitrogen oxides and some other solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body. While exhaust gas directly endangers human health, it also has a profound impact on the environment in which humans live. The sulfur dioxide in the exhaust gas has a strong irritating smell. When it reaches a certain concentration, it is easy to cause acid rain, causing soil and water acidification, and affecting the growth of crops and forests.

[0003] However, it still has some disadvantages. For example, due to the solid particles and harmful gases emitted from automobile exhaust, the traditional exhaust gas recovery device is relatively simple to handle, so these substances will still be discharged in large quantities, thereby polluting the surrounding environment and affecting people's health. In addition, the exhaust gas recovery effect is general and does not meet the exhaust gas emission standards, which is not conducive to people's long-term use.

[0004] In order to solve the above problems, the present application proposes a urea tail gas recovery and utilization device. Utility Model Content
