Embodiment Construction

[0023] See figure 1 , figure 2 , Figure 3a , Figure 3b , Figure 3c , the installation method of catalyst module in a kind of novel SCR denitrification reactor of the present invention, its specific steps are as follows:

[0024] Step 1. When installing the catalyst module of this layer, set the horizontal "main rail for hoisting" and the vertical "secondary rail for hoisting" at the bottom of the steel beam on the top surface of this layer (that is, the bottom of the steel beam supporting the catalyst module on the previous layer). The catalyst module enters the reactor through "lateral movement" of an electric or manual hoist on the "hoisting main rail". See accompanying drawing of the present invention " figure 1 "--" Schematic diagram of the elevation of the catalyst module in the SCR denitrification reactor." figure 1 " is the installation mode for installing one layer of catalyst. The installation of catalyst modules of other layers shall be carried out accordin...

Abstract

The invention discloses an assembly method for catalyst modules in a novel SCR (Selective Catalytic Reduction) denitration reactor. The method comprises the following four steps: step one, arranging a transverse hoisting main rail and a vertical hoisting secondary rail on a monorail hoist which is located on the bottom of a top steel beam of a layer when assembling the catalyst modules of the layer, and enabling the catalyst modules to enter a reactor along with transverse movement of a manual hoist or an electric hoist which is arranged on the hoisting main rail; step two, putting the catalyst modules down near the hoisting secondary rail after reaching main units through the hoisting main rail, then withdrawing from the electric hoist or manual hoist of the main rail; step three, manually assembling a secondary rail connection part, vertically moving the secondary rail connection part and a manual hoist to hoist the catalyst modules in determined positions; and step four, taking the secondary rail connection part down after a whole line of catalyst modules is assembled for each time and applying the secondary rail connection part to assembly of other lines or other layers. The assembly method for the catalyst modules in the novel SCR denitration reactor is a catalyst module assembling technique which is simple, reliable, easy to operate and convenient to assembly in site.

Description

technical field [0001] The invention relates to a method for installing a catalyst module in a novel SCR denitrification reactor in the field of environmental protection. It is an improvement on the catalyst module installation technology of the denitrification reactor with imported technology from abroad. The invention belongs to the selective catalytic reduction (SCR) flue gas denitrification technology in the field of environmental protection technology. Background technique [0002] At present, the Selective Catalytic Reduction (SCR) flue gas denitrification method is widely used in domestic and foreign projects due to its high efficiency and stable performance, and has become the mainstream technology for removing nitrogen oxides from exhaust gas. The SCR denitrification system refers to a reaction device system that reduces the nitrogen oxides in the flue gas to nitrogen and water by injecting ammonia into the flue gas under the action of a catalyst. The main equipme...
