Cool hydrogen-propelled cyclone quench box

A cool hydrogen-propelled cyclone quench box, comprising:

• a upper support plate;
• a round lower support plate;
• a cylindrical mixing chamber arranged at a center of the round lower support plate;
• four to six curved upper-level cyclone blades amounted in the cylindrical mixing chamber and having bottoms that are perpendicularly arranged on an upper layer vane support plate;
• four to six curved lower-level cyclone blades that are curved in a reverse direction to a curved direction of the curved upper-level cyclone blades, being amounted at an exit of the cylindrical mixing chamber, and having bottoms that are perpendicularly arranged on a lower layer vane support plate;
• three cylindrical swirl tubes arranged at outside of the cylindrical mixing chamber with an interval of 120° from each other, and tangentially connected to a body of cylindrical mixing chamber along a horizontal direction;
• three rectangular gas-liquid downcomers perpendicularly arranged outside of the cylindrical swirl tubes, having bottoms that are tangentially connected to an outer wall of the cylindrical swirl tube along a perpendicular direction, and having upper portions that are connected to a fluid inlet of the upper support plate;
• a cool hydrogen branch pipe arranged outside of the cylindrical swirl tubes and tangentially connected to the cylindrical swirl tube along a horizontal direction, and having an upper end that is connected to a cool hydrogen pipe outside of the upper support plate through a flange on the upper support plate.
