Title:
IMPROVED ELECTRO-PYROLYTIC FURNACE
Document Type and Number:
WIPO Patent Application WO/2022/012612
Kind Code:
A1
Abstract:
An electro-pyrolytic furnace comprises a housing (1), a heating pipe (2), a protective layer (108), and an electric heating wire (109). The heating pipe (2) has an "n" shape. The heating pipe (2) increases in diameter at a position where a gas pyrolysis chamber (A) is located, and an inner wall thereof is provided with uniformly distributed recessed points (201) to cause a flow to be in a turbulent state. The heating pipe (2) decreases in diameter, with the same wall thickness, in a region (B) where a rear gas discharge end portion of the gas pyrolysis chamber (A) is located. An increase in the volume of the gas pyrolysis chamber (A) extends a duration in which a gas flowing at a uniform velocity remains in a pyrolytic furnace, and ensures a high-speed reaction performed by a pyrolytic apparatus, thereby achieving thorough pyrolysis. The "n"-shaped heating pipe (2) fully utilizes transfer of heat to ensure that a gas is pre-heated before entering the gas pyrolysis chamber (A), thereby ensuring pyrolysis performance. The recessed points (201) arranged on the inner wall of the heating pipe (2) cause a stable gas flow to be in a turbulent state, thereby extending a gas pyrolysis duration, and ensuring thorough pyrolysis of the gas.
