I. Market Pain Point Analysis

1. Low Biogas Treatment Efficiency
   • Traditional pre-treatment equipment lacks precise temperature control, affecting the efficiency of subsequent processes such as desulfurization.
   • Large fluctuations in biogas temperature lead to unstable subsequent processes and poor purification effects.
2. Severe Energy Waste
   • A large amount of waste heat generated during biogas production is not effectively utilized.
   • Traditional cooling methods have high energy consumption, resulting in persistently high operating costs.
3. Poor Equipment Adaptability
   • Biogas compositions vary significantly across different gas sources, making conventional equipment difficult to universalize.
   • Performance is unstable when processing capacity changes, affecting continuous production.

II. System Process Flow
