Catalytic heating tubeIt is a tubular electric heating device that uses a catalyst to achieve efficient heat conversion. Its core function is to reduce the activation energy of the reaction through the catalyst, and promote chemical conversion or exhaust gas purification at lower temperatures.
Application scenarios:
Exhaust gas purification:
Mainly used for automobile exhaust treatment (such as three-way catalytic converters), decomposing harmful gases.
Industrial reactor:
Provide a stable heat source for exothermic reactions in chemical processes such as ammonia synthesis and alcohol dehydrogenation.
Customized equipment:
Suitable for scenarios that require precise temperature control, such as microfluidic chips and biosensors.
Resistance heating element: electrical energy → thermal energy conversion, spiral winding to improve thermal efficiency; Nickel chromium alloy, iron chromium aluminum.
Metal tube shell: pressure bearing and thermal conductive carrier, requiring corrosion/high temperature resistance; 316L stainless steel and titanium tube.
Catalyst carrier: provides a reactive surface, honeycomb structure increases contact area; Platinum/palladium coated ceramics.
Connection mechanism: combination of threaded rod and connecting sleeve to achieve modular assembly.
Structural characteristics:
Electronic control integrated system: supports external power supply to regulate temperature, optimizes energy consumption and catalytic efficiency through dynamic heating strategy.
Multi layer composite design:
Metal shell: usually made of stainless steel, titanium or zirconium alloy pipes (diameter Ø 11mm-50mm), which balance high temperature resistance and corrosion resistance.
Heating unit: Built in spiral resistance wire, filled with high thermal conductivity insulation material (such as crystalline magnesium oxide powder) to ensure efficient conduction of electric heat to the pipe wall.
Mechanical components: including threaded connecting rods, connecting sleeves, and nuts, facilitating modular installation and maintenance.
