[0035] It should be noted that the first temperature and pressure monitoring device 210 is arranged at the inlet of the temperature and pressure double increasing device 200, the first temperature and pressure monitoring device 210 is used for detecting the temperature and pressure of the steam entering the temperature and pressure double increasing device 200, the second temperature and pressure monitoring device 220 is arranged at the outlet of the temperature and pressure double increasing device 200, the second temperature and pressure monitoring device 220 is used for detecting the temperature and pressure of the steam entering the temperature and pressure double increasing device 200, in an embodiment, the first temperature and pressure monitoring device 210, the second temperature and pressure monitoring device 220 and the temperature and pressure double increasing device 200 are all signal connected with the controller, the controller can adjust the operation of the temperature and pressure double increasing device 200 according to the information fed back by the first temperature and pressure monitoring device 210 and the second temperature and pressure monitoring device 220, for example, when the temperature and pressure double increasing device 200 is operated in the first mode, if the temperature and pressure information fed back by the second temperature and pressure monitoring device 220 is lower than the expected temperature and pressure range, the controller controls the temperature and pressure double increasing device 200 to operate in the second mode, that is, to control the temperature and pressure double increasing device 200 to accelerate operation, when the temperature and pressure information fed back by the second temperature and pressure monitoring device 220 is in the expected temperature and pressure range, the controller controls the temperature and pressure double increasing device 200 to keep operating in the first mode, when the temperature and pressure information fed back by the second temperature and pressure monitoring device 220 is higher than the expected temperature and pressure range, the controller controls the temperature and pressure double increasing device 200 to operate in the third mode, that is, to control the temperature and pressure double increasing device 200 to decelerate operation, to enter the energy saving mode, the expected temperature and pressure range can be set to 90%~110% of the standard value.

[0036] The steam conveying pipeline 100 is provided with the temperature and pressure double increasing device 200, steam in the steam conveying pipeline 100 is transported in a range-increasing mode, the diameter and conveying distance of the steam conveying pipeline 100 can be broken through, the diameter of the steam conveying pipeline 100 can be reduced to the maximum extent when the diameter of the steam conveying pipeline 100 is selected, the investment of the steam conveying pipeline 100 is reduced, the pipe loss of the steam conveying pipeline 100 at low load is reduced, and the energy saving effect is more significant at the low load working condition of the steam conveying pipeline 100; the arc-shaped heat preservation interlayer 130 is additionally arranged between the inner heat preservation layer 120 and the outer heat preservation layer 140 of the steam conveying pipeline 100, and the heat preservation interlayer 130 is located at the top of the inner heat preservation layer 120, which can effectively reduce the heat loss of the upper part of the steam conveying pipeline 100, and through the support of the heat preservation interlayer 130 to the outer heat preservation layer 140, the heat preservation performance and service life of the outer heat preservation layer can be improved. The steam range-increasing mode conveying system with the temperature and pressure double increasing device provided in the embodiment can be used for steam conveying at an ultra-long distance (for example, 60 km to 80 km), and can meet the use requirements of end users.

[0037] It should be noted that the heat preservation structure in the conventional steam conveying pipeline 100 is found to have a heat loss at the top of the steam conveying pipeline 100 that is obviously higher than that at the side and bottom of the steam conveying pipeline 100 during use, and as the use time increases, the heat preservation structure at the top of the inner pipe 110 is compressed due to gravity, which causes the thickness of the heat preservation structure at the top of the inner pipe 110 to be reduced, thereby affecting the heat preservation effect of the pipeline. In the embodiment, the arc-shaped heat preservation interlayer 130 is located at the top of the inner heat preservation layer 120, which can effectively reduce the heat loss of the upper part of the steam conveying pipeline 100, and the heat preservation interlayer 130 can form a gap between the inner heat preservation layer 120 and the outer heat preservation layer 140 at the top of the inner pipe 110, thereby reducing the heat loss. Even if the inner heat preservation layer 120 and the outer heat preservation layer 140 at the top of the inner pipe 110 are compressed due to gravity, the heat preservation interlayer 130 can form an annular or arc-shaped gap (air has a low heat conductivity) between the inner heat preservation layer 120 and the outer heat preservation layer 140, so as to ensure the heat preservation effect of the inner pipe 110.

The second reflective layer 170 is a reflective aluminum foil with a thickness of 7um-15um, and the arrangement of the second reflective layer 170 can effectively reduce the heat transfer between the adjacent outer thermal insulation layers 140, thereby improving the thermal insulation effect of the outer thermal insulation layer 140.

[0040] The steam conveying pipeline 100 further comprises a third reflective layer 180, which is wrapped on the outer side of the thermal insulation interlayer 130 and the outer side of the inner thermal insulation layer 120 of the outermost layer.

[0042] In a possible implementation, the cross section of the thermal insulation interlayer 130 perpendicular to the axis of the steam conveying pipeline 100 forms an angle between the two ends in the circumferential direction of the steam conveying pipeline 100 and the line connecting the center of the steam conveying pipeline 100, which is greater than or equal to 90° and less than or equal to 180°, that is, the thermal insulation interlayer 130 can adopt an arc structure corresponding to one fourth of a whole circle to one half of a whole circle, so that the side of the thermal insulation interlayer 130 facing the inner pipe 110 can be fitted with the outer periphery of the inner thermal insulation layer 120 of the outermost layer, facilitating the fixation of the thermal insulation interlayer 130, and preferably the cross section of the thermal insulation interlayer 130 perpendicular to the axis of the steam conveying pipeline 100 forms an angle between the two ends in the circumferential direction of the steam conveying pipeline 100 and the line connecting the center of the steam conveying pipeline 100, which is 120°, that is, the thermal insulation interlayer 130 can adopt an arc structure corresponding to one third of a whole circle.

[0043] The material of the inner thermal insulation layer 120 is specifically one of silicate material, glass wool material, and nano aerogel thermal insulation material, that is, the inner thermal insulation layer 120 can be selected as a silicate product, or a glass wool product, or a nano aerogel product, when the inner thermal insulation layer 120 is the silicate product or the glass wool product, the inner thermal insulation layer 120 can adopt a 40mm-50mm thick thermal insulation needle blanket, when the inner thermal insulation layer 120 is the nano aerogel product, the inner thermal insulation layer 120 can adopt a 10mm thick nano aerogel thermal insulation blanket, in addition, the inner thermal insulation layer 120 can also adopt a 25mm thick long-acting high-temperature thermal insulation inner blanket.
