Denitration flue reactor wallboard

Abstract

The invention relates to a denitration flue reactor wallboard, which comprises a wallboard body and a support frame, the support frame is positioned outside the wallboard body. The support frame is positioned outside the wallboard body, the support frame manufactured by the angle iron and H-type steel faces to the external part of the gas flue, the wallboard body is positioned in the gas flue, the support frame manufactured by the angle iron and H-type steel which faces outside can be packed by an outer insulation material, the beautiful appearance is not influenced, and the normal usage condition is not prevented, the production cost is reduced, and the working time can be saved.

Description

technical field [0001] The invention relates to a gas denitration device, in particular to a denitration flue. Background technique [0002] NOx (NO and NO2) is one of the main pollutants in the atmosphere. Selective catalytic reduction (SCR) is to reduce it with ammonia (NH3) under certain temperature conditions (280-400 °C) with the help of a catalyst. NOx process. The wall panel of the denitrification flue reactor is a structure for maintaining and carrying ceramic catalysts and equipment to prevent flue gas leakage. When making the wall panel of the denitrification flue reactor, the support frame made of angle steel, H-shaped steel and other profiles is generally installed on the inside of the wall panel body, that is, the inside of the flue, and the wall panel body is installed on the outside of the support frame. The body of each section of the wall panel is welded together by profiles, and gaps are likely to occur between the welds. In order to prevent the leakage o...

Problems solved by technology

When making the wall panel of the denitrification flue reactor, the support frame made of angle steel, H-shaped steel and other profiles is generally installed on the inside of the wall panel body, that is, the inside of the flue, and the wall panel body is installed on the outside of the support frame. The body of each section of the wall panel is welded together by profiles, and gaps are likely to occur between the welds. In order to prevent the leakage of smoke, a number of sealing strips made of thin steel plates (such as δ3) steel plates are installed inside, which is inconvenient to install and also difficult to install. Waste time, waste materials, increase unnecessary production costs
