Working principle: steam enters the communicating vertical pipe 14 through the steam inlet pipe 12, and continuously gives a certain pressure to the action blocking ball 20 in the conical cavity 18 on the communicating vertical pipe 14, so that the action blocking ball 20 presses the telescopic middle rod 21 to move towards the telescopic sleeve 22, and the pressure spring 23 is compressed, so that the entering steam is decelerated and enters.
Gas is introduced into the gas inlet pipe 46 through the gas manifold 47, and the gas enters the intermediate heat-insulating chamber 45 through the gas inlet pipe 46. The rear steam enters the steam circulation intermediate pipe 35 of the steam circulation unit 34 through the conveying cavity 19, the steam in the steam circulation intermediate pipe 35 is split at the position connected with the first steam circulation branch pipe 36, and part of the steam enters the first steam circulation branch pipe 36; the steam in the steam circulation intermediate pipe 35 continues to flow to the position connected with the second steam circulation branch pipe 38 and is split again, and part of the steam enters the second steam circulation branch pipe 38; the steam in the steam circulation intermediate pipe 35 continues to flow to the position connected with the third steam circulation branch pipe 40 and is split again, and part of the steam enters the third steam circulation branch pipe 40; the steam in the steam circulation intermediate pipe 35 continues to flow to the position connected with the fourth steam circulation branch pipe 42 and is split again, and part of the steam enters the fourth steam circulation branch pipe 42; the steam in the rear steam flow intermediate pipe 35, the first steam flow branch pipe 36, the second steam flow branch pipe 38, the third steam flow branch pipe 40 and the fourth steam flow branch pipe 42 enters the collecting main pipe 43, flows into the condensation water cavity 11 through the return pipe 44, and is discharged through the condensation water drain pipe 13. The process preheats the internal structure, ensuring the internal temperature.
Finally, the heat transfer oil passes through the heat transfer oil inlet pipe 29, and flows along the heat transfer oil flow channel 33 formed between the upper fixed baffle 26 and the lower fixed baffle 27 until reaching the other end of the heat transfer oil flow channel 33, and then flows out through the heat transfer oil outlet pipe 30. The heat conduction oil exchanges heat with the steam circulation unit 34 inside to achieve the heated effect, because the steam in the steam circulation intermediate pipe 35 is continuously split, the steam in the steam circulation intermediate pipe 35 circulates to different stages, so that the unreduced steam is added into each section of space inside the heater shell 1 to heat the heat conduction oil (the unreduced steam refers to the steam which is not directly subjected to heat exchange and cooling, but the intermediate flow process still has heat loss, and compared with the steam which is directly subjected to heat exchange and cooling, the steam is still in a higher temperature state). The steam exchanges heat and then cools to form condensate, and the condensate flows into the condensate cavity 11 through the return pipe 44 and is discharged through the condensate drain pipe 13.
