Description

TECHNICAL FIELD

[0001] The utility model relates to a solid ammonia storage tank for automobile exhaust treatment. BACKGROUND

[0002] The selective catalytic reduction reaction (SCR) is a treatment process for NOx in automobile exhaust, that is, under the action of a catalyst, ammonia or urea is sprayed as a reducing agent to reduce NOx in the exhaust to N2 and H2O to achieve the purpose of reducing air pollution. Most of the automobile exhaust treatment on the market uses urea solution. In the process of automobile exhaust treatment, the urea solution is sprayed into the exhaust pipe and mixed with high-temperature exhaust gas. The urea is first decomposed into ammonia and carbon dioxide, and then the ammonia reacts with nitrogen oxides to generate harmless nitrogen and water. Among them, the ammonia obtained by the decomposition of urea is mainly liquid ammonia, and the ammonia content is low and needs to be decomposed. Therefore, the whole selective catalytic reduction reaction has the problems of slow reaction and energy consumption and emission increase.

[0003] Research has found that ammonia storage material can be used as a medium for storing ammonia gas. Ammonia gas can be adsorbed in ammonia storage material powder. When the temperature rises, ammonia gas is released, so it can directly react with nitrogen oxides in automobile exhaust to generate harmless nitrogen and water. However, there is no plastic solid ammonia storage tank structure suitable for passenger cars on the market. The temperature resistance of plastic materials is one of the important reasons.

[0004] Therefore, it is necessary to provide a solid ammonia storage tank that can safely and effectively provide ammonia gas for automobile exhaust treatment, improve the efficiency of the selective catalytic reduction reaction, and achieve the benefits of energy saving and emission reduction.
