Online catalyst regeneration system

Abstract

The invention relates to an online catalyst regeneration system. The online catalyst regeneration system comprises: catalyst unit equipment, which is connected with a bag-type dust collector through a first air inlet valve pipeline, wherein an air outlet of the catalyst unit equipment is connected with a next procedure through a first air outlet valve pipeline; and a regeneration system, wherein one end of the regeneration system is connected with a gas inlet of the catalyst unit equipment through a second gas inlet valve pipeline, the other end of the regeneration system is connected with a gas outlet of the catalyst unit equipment through a second gas outlet valve pipeline, and the regeneration system comprises heating equipment, a first main pipeline connected with the heating equipment and the second gas inlet valve pipeline and provided with a circulating fan, and a second main pipeline connected with the heating equipment and the second gas outlet valve pipeline and communicating with a nitrogen input device. The catalyst unit equipment comprises a plurality of unit modules which are independently arranged, and the plurality of unit modules can realize independent on-off. The online catalyst regeneration system can effectively guarantee online regeneration of a catalyst, and operation of a main machine is not affected.

Description

technical field [0001] The invention belongs to the technical field of desulfurization and denitrification catalyst regeneration, and in particular relates to an online regeneration catalyst system. Background technique [0002] In recent years, due to the rapid development of industry, serious air pollution and acid rain have formed in some areas of the country. This is because in the production process, various industries emit a large amount of harmful smoke and harmful gases, such as sulfur dioxide and various nitrogen-containing compounds. Therefore, we need to use desulfurization and denitrification equipment to remove these pollutants as much as possible. In such an environment, the production and application of desulfurization and denitrification equipment is of great significance. Most of the flue gas denitrification process in my country chooses the SCR method, which has no by-products, does not cause secondary pollution, and has high denitrification efficiency. ...
