[0027] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0028] Example

[0029] like Figure 1-6As shown, this utility model provides an exhaust gas processor, which includes an outer shell 1 for filling a catalyst 3, a gas flow chamber 2 inside the outer shell 1, the gas flow chamber 2 being connected to a heater 5 through a connecting tee 4 outside the outer shell 1, and the third port of the connecting tee 4 being an exhaust gas inlet 6.

[0030] When using the aforementioned waste gas processor, the heater needs to be started in advance for preheating. When the heater temperature reaches 200℃, the waste gas enters through the waste gas inlet on the side connected to the tee, comes into contact with the heating rod of the heater, and raises the temperature of the waste gas to reach the optimal reaction temperature, and then enters the gas flow chamber. The gas flow chamber is made of sintered stainless steel powder, with a filtration accuracy of up to 5μm. The waste gas entering the gas flow chamber undergoes preliminary filtration and is dispersed into the outer shell filled with catalyst.

[0031] The catalyst is primarily composed of platinum and palladium, with nano-sized platinum and palladium particles sprayed onto granular molecular sieves to increase the contact area and reaction efficiency. The space between the gas flow chamber and the outer shell is completely filled with the catalyst. Waste gas entering the chamber is adsorbed by the catalyst and undergoes an oxidation reaction, converting hydrocarbons in the waste gas into water and carbon dioxide, which are then released into the atmosphere through the outer shell, achieving zero-pollution emissions.

[0032] Because the catalyst is not consumed in the reaction and possesses high stability and a long service life, the exhaust gas processor does not require frequent filter replacements. Both the gas flow chamber and the outer shell utilize a powder sintering design, increasing safety during use. Exhaust gas can only enter and exit the chamber through tiny pores in the sintered shell, dispersing it into multiple fine airflows. This ensures a more uniform distribution of the exhaust gas within the reaction chamber, leading to a more complete reaction.

[0033] The heater is equipped with a built-in temperature control module, which can precisely control the temperature to ensure that the internal reaction temperature of the exhaust gas processor remains stable at around 200℃, which is the optimal activity condition for the catalyst. The temperature control module also has a high-temperature alarm function; when the internal temperature exceeds 250℃, it will issue a high-temperature alarm signal to alert on-site maintenance personnel to the abnormal operating condition. Simultaneously, it will cut off the heater's power supply, stopping heating and ensuring operational safety.
