AI Technical Summary
The problems of coking of tar vapor and short service life of the inner cylinder have not been effectively solved in existing waste gas heat recovery heat exchangers, resulting in decreased heat transfer efficiency and increased safety hazards.
The inner cylinder is filled with a thermally conductive filler on the outside, and the filling depth of the middle thermally conductive cavity is 0.55-0.85 times the length of the inner cylinder. It combines thermally conductive and heat-storing powder and thermally conductive heat-storing body, and is equipped with a one-way valve to regulate the pressure difference between the inside and outside. A boundary layer fluid rotation turbulence device is set on the inner wall of the inner cylinder to optimize the structure, reduce tar adhesion and extend the service life of the inner cylinder.
This improved the heat transfer efficiency of the heat exchanger, extended the service life of the inner cylinder, reduced construction costs, and prevented safety accidents.
