As an advanced environmental protection equipment, the low-temperature catalytic principle of Cold Catalyst Filter mainly relies on the special properties and structural design of the catalyst to achieve efficient conversion of harmful substances in exhaust gas at relatively low temperatures.

First of all, the core of this product lies in the low-temperature catalyst it selects. These catalysts are usually composed of a mixture of one or more metal oxides (such as manganese-based, vanadium-based, etc.), which show extremely high catalytic activity at low temperatures. Unlike traditional high-temperature catalysts, low-temperature catalysts can effectively promote the reduction or oxidation reactions of harmful substances such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) within a lower temperature range (such as below 150°C), thereby converting them into harmless or low-toxic substances.

Secondly, the structural design of Cold Catalyst Filter also fully considers the optimization of gas flow and catalytic reaction. The porous materials used as carriers inside the filter have high specific surface area and excellent mass transfer performance, which can ensure full contact between exhaust gas and catalyst. At the same time, the uniform distribution of the catalyst on the carrier also further improves the efficiency and stability of the catalytic reaction.

During the catalytic reaction, harmful substances in the exhaust gas are first adsorbed onto the catalyst surface, and then chemical reactions occur under the action of the catalyst. Taking the conversion of nitrogen oxides as an example, when nitrogen oxides meet a reducing agent (such as ammonia) on the catalyst surface, a selective catalytic reduction (SCR) reaction occurs to generate nitrogen and water. This process not only reduces the emission concentration of nitrogen oxides, but also realizes the resource utilization of harmful substances.

In summary, the low-temperature catalytic principle of Cold Catalyst Filter mainly depends on its selected low-temperature catalyst and optimized structural design. Through the low-temperature activity and efficient mass transfer performance of the catalyst, the product can achieve efficient conversion of harmful substances in the exhaust gas at a lower temperature, providing strong support for the company's environmental protection and emission reduction. At the same time, with the increasingly stringent environmental protection regulations and the continuous advancement of technology, Cold Catalyst Filter is expected to be widely used and promoted in more fields.
