The heating means of above-mentioned steam hot oil heater comprise the steps:
1) opens first oil inlet pipe valve 71 and flowline valve 81, and unlatching is arranged on the oil circulating pump 72 on the oil inlet pipe 7, under the effect of oil circulating pump 72, conduction oil in the conduction oil oil-feed header 73 enters inlet space 111, then enter steam chest 12 and the first heating clamber 132 by the heat-conducting oil pipes 2 that is connected with inlet space 111, conduction oil through the first heating clamber 132 passes through 113 → steam chest, 12 → the second heating clambers, 133 → steam chest, 12 → the second transfer grease chambeies, steam chest 12 → the first transfer grease chambeies, 114 → steam chest, 12 → the 3rd heating clamber 134 → steam chests 12 successively, arrive out at last grease chamber 112, enter the fuel-displaced header 82 of conduction oil by flowline 8; Simultaneously, open electric auxiliary hot heater 131, conduction oil is heated, because when the steam hot oil heater has just been started working, steam does not enter steam chest 12, heat-conducting oil pipes 2 temperature in the steam chest 12 are lower, can carry out preheating by 131 pairs of conduction oils of the auxiliary hot heater of electricity first, and regulate the power output of electric auxiliary hot heater 131 until the electric auxiliary hot heater 131 of stopping using according to the lifting of conduction oil oil outlet temperature.
2) after the conduction oil normal circulation, open first steam pipe bypass valve 94, crack steam outlet tube valve 101 again, make a small amount of steam enter steam chest 12 from steam outlet pipe 10, heat-conducting oil pipes 2 is carried out lentamente reverse heating, excessive to prevent admission, make that heat-conducting oil pipes 2 cold and hot non-homogeneous expansions are even, thermal stress is excessive, thereby cause heat-conducting oil pipes 2 weld bonds to split or swollen mouth unclamps the generation leakage of oil.
3) then, open drain pipe valve 122, the condensate water in the steam chest 12 is discharged steam chest 12 by drain pipe 121.
4) check vaporium Pressure gauge 123, when Pressure gauge 123 rising, continue slowly to open steam outlet tube valve 101, make steam enter steam chest 12 from steam outlet pipe 10 and discharge from drain pipe 121 again.
5) oil thermometer 83 on the inspection flowline 8, when oil thermometer 83 slowly rises reposefully, open gradually large steam outlet tube valve 101, check drain pipe 121 steam discharge situations, when hydrophobic amount reduces gradually, emit white vapour then become, until emit white vapour to become gradually when arranging superheated steam, open steam steam inlet pipe valve 91, close drain pipe valve 122.After opening steam inlet pipe valve 91 fully, open again steam inlet pipe valve 101 fully, steam off pipe bypass valve 94 again, all steam were flowed through in steam chest 12 and were used to downstream user after 3 pairs of conduction oils of each gripper shoe fully heat again this moment.
In addition, between the oil inlet pipe 7 of heater and flowline 8, be provided with bypass valve 75, in order to when operating condition changes, in time to adjust to satisfy need of production.
The diameter of heat-conducting oil pipes 2 is decided according to the actual requirements, and except above-mentioned 20mm, 30mm, can also select diameter is other big or small heat-conducting oil pipes 2 such as 25mm, 35mm or 40mm.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
