Problems solved by technology

[0003]1. Nitrogen oxides seriously damage the atmospheric ozone layer; 2. The affinity between nitrogen oxides and human red blood cells is 1000 times higher than that of carbon monoxide, endangering human health; 3. Acid rain harms crops The growth of crops reduces crop yields, and even the crops fail, while sulfides and nitrogen oxides are the chief culprits of acid rain damage

Embodiment 1

[0026] Embodiment two

Embodiment 2

[0028] The second embodiment can be regarded as a way in which the spoilers 2 are arranged staggeredly in different directions.

[0029] Figure 5 It is a schematic diagram of the comparison of the turbulence effect of the present invention with or without the spoiler. This figure is obtained by simulating the flue gas flow and its chemical reaction status through the CFD simulation software fluent under the condition of a normal denitrification catalyst flow rate of 4m / s, where a is the The result obtained from the structure of Example 2 of this embodiment, b is the test result obtained by removing the internal spoiler structure.

Abstract

The invention discloses a ribbed catalyst structure, which comprises a plurality of passages provided with inlet and outlet end parts and arranged along the longitudinal direction, wherein the passages are used for flowing gas mixtures to pass through, the inner surfaces of the passages are coated with catalysts reacting with the flowing gas mixtures, the inner walls of the passages are provided with at least one spoiler, and the spoilers can be arranged along the same direction or the different directions. The spoilers are arranged on the inner walls of the passages for the catalyst, so the ribbed catalyst structure improves the turbulence effect of flue gas in catalyst holes and prolongs the residence time of the flue gas, thereby improving the denitrating efficiency of the fuel gas.

Description

technical field [0001] The present invention relates to a ribbed catalyst structure. Background technique [0002] my country's energy composition is dominated by coal. Among the power fuels, coal and oil with high and medium sulfur content occupy a considerable proportion. Under the situation of sustained and stable growth of the national economy, the contradiction between energy development and utilization and environmental protection is particularly serious. protrude. Growing SO 2 The discharge of nitrogen oxides and nitrogen oxides has brought huge losses to the national economy, and has seriously damaged the environment on which human beings live. The harm is mainly manifested in: [0003] 1. Nitrogen oxides seriously damage the atmospheric ozone layer; 2. The affinity between nitrogen oxides and human red blood cells is 1000 times higher than that of carbon monoxide, which endangers human health; 3. Acid rain harms the growth of crops, reduces crop production, and eve...
