Low-resistance and energy-saving flue gas denitration catalyst module

Abstract

The invention discloses a low-resistance and energy-saving flue gas denitration catalyst module, and relates to the technical field of flue gas denitration. The module comprises a module base, a module frame is arranged on the module base, the module frame comprises a bottom sealing plate, a top cover plate, a catalyst framework, an end wallboard and a side wallboard, the bottom sealing plate is located above the module base, the end wallboard and the side wallboard are vertically arranged surrounding the bottom sealing plate respectively, the top cover plate covers the tops of the end wallboard and the side wallboard, the catalyst framework is evenly distributed in the module frame in a W shape, and a catalyst is arranged in the catalyst framework. The catalyst layer in the whole module is W-shaped, so compared with a catalyst module adopting common catalyst layers which are arranged in parallel, the catalyst module of the invention has the advantages of high filling amount, strong denitration ability, and realization of space saving, small size, low resistance and low energy consumption under the same filling amount.

Description

technical field [0001] The invention relates to the technical field of flue gas denitrification, in particular to a low-resistance and energy-saving flue gas denitrification catalyst module. Background technique [0002] The flue gas produced by burning coal, fuel oil, and gas contains harmful gases such as sulfur dioxide and nitrogen oxides. These harmful gases are discharged into the atmosphere, which can easily cause acid rain, damage the ecological environment, and affect human health. Therefore, my country's relevant environmental protection regulations Strict control standards have been put forward for the allowable emission concentration of nitrogen oxides in flue gas. [0003] There are many methods of coal combustion pollution control, usually divided into three categories, namely denitrification before combustion, denitrification during combustion and denitrification after combustion (flue gas denitrification), among which denitrification after combustion of flue ga...

AI Technical Summary

Problems solved by technology

The following problems exist: the module designed according to the full load of the sintering machine has a large pressure loss in the actual operation process, which affects the normal operation of the denitrification and desulfurization system, affects the denitrification and desulfurization efficiency, and consumes a lot of energy.

Due to the large resistance of the module, it cannot meet the operation needs, which has caused great obstacles to the promotion and application of the clover catalyst.
