Fig. 2 is the sectional view of Fig. 1 along the A-A direction;
Fig. 3 is the utility model high-energy radiation cover unfolded structural representation.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Shown in Fig. 1 to 3; Said oil refining furnace with energy-saving and emission-reduction function comprises oil refining furnace cylindrical shell 6, and the inwall of said oil refining furnace is provided with furnace wall, and the top of said oil refining furnace barrel is a convection chamber 2; The below of said convection chamber 2 is a radiation chamber 1; The inside of said radiation chamber 1 and convection chamber 2 forms the hollow burner hearth, and said radiation chamber 1 comprises a furnace wall and a circle radiating furnace tube 7 that is provided with around said furnace wall, and said convection chamber 2 comprises a furnace wall and a circle convection tubes that is provided with around said furnace wall; The fuel inlet place, center of said cylindrical shell 6 lower ends is equipped with burner 3; In the said radiation chamber 1 high-energy radiation cover 4 is installed, said high-energy radiation cover 4 is fixed on the oil refining furnace cylindrical shell 6, has a plurality of equally distributed water conservancy diversion holes 5 on the said high-energy radiation cover 4.Oil fuel sprays into from the radiation chamber bottom through burner, and the interior flow media of radiating furnace tube is absorbing radiation chamber heat continuously; Said radiating furnace tube is positioned at said burner hearth, is provided with along the radiation chamber furnace wall, and is serpentine tube or spiral pipe; Said convection tubes is serpentine tube or spiral pipe.Said radiation chamber top is convection chamber, and the convection chamber structure is made up of furnace wall and convection tubes, and after the radiation chamber high-temperature flue gas got into convection chamber, the high-temperature flue gas waste heat was absorbed by convection heating surface again.
The xsect of said high-energy radiation cover can be selected multiple shape, circular or padmasana.Said high-energy radiation cover is coaxial with burner.Said pod apertures hole dia is 20~40mm, and distance is 150~200mm between the adjacent water conservancy diversion hole.Said water conservancy diversion hole and be 10 °~45 ° perpendicular to the angle between the direction of high-energy radiation cover sidewall.
