Description

Technical Field

[0001] The invention relates to the technical field of catalytic devices, in particular to a catalytic device of a non-precious metal catalyst. Background Art

[0002] Selective catalytic reduction (SCR) is a technology to reduce nitrogen oxide (NOx) emissions. The core of this technology is to use ammonia (NH3), urea or other nitrogen-containing compounds as reducing agents under the action of catalysts to react with NOx to generate harmless nitrogen (N2) and water (H2O). It is widely used in the fields of power, chemical, steel, petrochemical, glass, diesel exhaust treatment, etc.

[0003] Catalysts can be divided into precious metal catalysts and non-precious metal catalysts according to the preciousness of the metals in their components. Although precious metal catalysts have better catalytic effects, their utilization rate is low due to their high cost. The utilization rate of non-precious metal catalysts is much higher than that of precious metal catalysts.

[0004] The optimal reaction temperature of non-precious metal catalysts is between 250°C and 450°C. Exceeding or falling below this temperature range will affect the catalytic effect of the catalyst. The flue gas flows from top to bottom in the flue. The temperature of the flue gas above may exceed the optimal reaction temperature, and the flue gas below may be lower than the reaction temperature. The traditional catalytic device lacks a cooling and preheating device for the flue gas, so that the catalyst located above and the catalyst below cannot obtain a good catalytic effect. In addition, the flue gas contains a large amount of dust and other particulate matter. These substances adhere to the catalyst surface and may affect the reaction of the catalyst with ammonia mist and nitrogen oxides in the flue gas, and may cause blockage of the honeycomb holes of the catalyst bed. When the flue gas flows from top to bottom, the utilization rate of the upper surface of the catalyst is higher, while the utilization rate of the lower surface of the catalyst is lower. Therefore, based on the above problems, the present invention provides a catalytic device of a non-precious metal catalyst. Summary of the invention

The preheated water enters the heat dissipation copper tube 404, and the transmission component b302 drives the gear 406 to rotate. The rotation of the gear 406 drives the blades of the fan 405 to rotate, thereby dissipating the heat of the heat dissipation copper tube 404.
