in the application, when in use, the radiation calandria 9 is slowly placed downwards along the inner walls of the sleeve 35 and the limiting ring 20, the mounting pipe 26 at the bottom of the radiation calandria 9 is communicated with the inside of the connecting pipe 10 through the inner wall of the communicating pipe 25, the sealing ring 30 at the bottom of the radiation calandria 9 enters the sealing groove 29 at the top of the supporting frame 28, the supporting frame 28 supports the sealing ring 30 and further supports the radiation calandria 9, the limiting column 23 on the radiation calandria 9 enters the hanging frame 21 at the top of the hanging frame 21 to further support the radiation calandria 9, then the feed pipe 7 is butted with the radiation calandria 9, the feed pipe 7 and the radiation calandria 9 are connected and sealed through the fixing ring 33, then the second asbestos rope 34 is filled between the sleeve 35 and the second asbestos rope 34, so that the combustion medium can be conveyed in the radiation calandria 9 through the feed pipe 7, the oil-gas combined burner 4 is used for igniting so that the combustion medium in the radiation calandria 9 is combusted, the heavy oil in the radiation chamber steel structure 1 is heated through heat exchange of the radiation calandria 9, so that the use is convenient, the radiation calandria 9 is convenient to take out and clean subsequently, and the reduction of the heat exchange effect of the radiation calandria 9 caused by scaling of the inner wall of the radiation calandria 9 is avoided;
in the application, oil vapor generated after heavy oil is heated and vaporized enters the conveying pipe 38 through the vertical pipe 37, because the conveying pipe 38 adopts an S-shaped design, the oil vapor is adhered to the inner wall of the convection pipe 39 at a turning position and is converted into liquid state to fall down for further heating and vaporization, and the rest part of crude oil to be processed is discharged through the convection pipe 39 for further processing;
in the application, after the convection tube 39 and the conveying tube 38 are used for a long time, the inner walls of the convection tube 39 and the conveying tube 38 can have a scaling phenomenon, and the inner walls of the convection tube 39 and the conveying tube 38 need to be cleaned, so that the phenomenon that oil and steam are heated unevenly is avoided, at the moment, the rocking handle 13 is rotated, the driving shaft 15 is rotated to drive the driving bevel gear in the redirection box 14 to rotate, the driving bevel gear drives the driven shaft 16 to rotate through the driven bevel gear so as to drive the wire winding disc 17 to rotate, so that the wire winding disc 17 winds the pulling rope 18, meanwhile, the rotating shaft 41 is rotated through the pulling force of the pulling rope 18, so that the pressing plate 40 rotates, the pressure of the pressing plate 40 on the connecting column 44 fails, the connecting column 44 drives the connecting plate 45 to move under the elastic action of the spring 46, so as to drive the convection tube 39 to move, so that the limiting pin 42 is separated from the limiting groove 43, at the convection tube 39 and the conveying tube 38 can be moved out through the explosion-proof door, and the insides of the convection tube 38 can be cleaned;
in practical use, the convection tube 39 can be provided with a slide block, and the inner wall of the convection chamber 2 is provided with a slide rail, and the slide rail is L-shaped as a whole, so that the convection tube 39 can be conveniently arranged;
in this application, finally carry out recovery processing to tail gas, all do not belong to the scope of protection of this application.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
