Description

Technical Field

[0002] The high-temperature steam dewatering system is a key part in the industrial and energy fields. It is used to remove moisture from high-temperature steam to obtain drier steam. This system is usually used in steam power plants, chemical plants, refineries and other industrial processes. During the tobacco production process, the tobacco shred feeder needs to use the high-temperature steam dewatering system to spray dry steam into the tobacco shred feeder for heating.

The heat exchange pipe 33 is connected inside the outer frame 34. The heating plate 31 is connected inside the outer frame 34. A heat supply pipe 32 is connected between the heating plate 31 and the heat exchange pipe 33. A temperature signal detector 4 is connected to the left part of the superheater assembly 3. A first pressure signal detector 5 is connected to the left side of the superheater assembly 3 near the temperature signal detector 4. A first direct discharge valve pipe 11 with a heat preservation function is connected to the lower side of the left part of the superheater near the left side of the first pressure signal detector 5. An outlet valve 6 is connected to the left part of the superheater near the left side of the first pressure signal detector 5. A steam recovery assembly 7 is connected to the left side of the outlet valve 6. The steam recovery assembly 7 includes a steam recovery tank, a hot gas pipe, a recovery valve, an auxiliary pipe, a discharge pipe and a check valve pipe. The steam recovery tank is connected to the left side of the outlet valve 6. The upper left side of the steam recovery tank is connected to a hot gas pipe. A recovery valve is connected to the lower part of the steam recovery tank. A discharge pipe is connected to the lower part of the recovery valve. An auxiliary pipe is connected to the upper part of the steam recovery tank. The auxiliary pipe is connected to the left part of the hot gas pipe. A check valve pipe is connected to the lower left side of the hot gas pipe. The lower part of the check valve pipe is connected to the left part of the discharge pipe. A flow detection assembly 16 is connected to the left part of the steam recovery assembly 7. The flow detection assembly 16 includes a protective shell and an electromagnetic flow detector. The electromagnetic flow detector is connected to the left part of the steam recovery assembly 7. The protective shell is connected to the outside of the electromagnetic flow detector. It further includes a pressure compensation mechanism.

A transmitter 81 is connected to the right side of the second steam inlet pipe 10 near the second pressure signal detector 8. A second inlet valve 9 is connected to the right side of the second steam inlet pipe 10 near the transmitter 81.

[0021] As Figure 1 and Figure 2 shown in the figure, it further includes a pressure relief valve pipe 12. The pressure relief valve pipe 12 is connected to the lower side of the superheater assembly 3.

[0022] When dehydrating the cut tobacco feeder in the workshop with high-temperature steam, this device can be used. It should be noted that first, open the first direct exhaust valve pipe 11 to discharge the condensate remaining in the first direct exhaust valve pipe 11, and then close the first direct exhaust valve pipe 11 again. Then, open the first inlet valve 2 so that the first steam inlet pipe 1 inputs steam into the superheater assembly 3. Subsequently, the superheater assembly 3 heats the steam. The wet steam passes through the heat exchange pipe 33 and contacts the heat transfer surface of the high-temperature heat source, and the heat energy is transferred to the steam to increase its temperature, completing the heating process of the steam. At this time, the temperature signal detector 4 detects the hot steam output by the superheater assembly 3. When the steam temperature is lower than the standard temperature, close the outlet valve 6, and at the same time open the first direct exhaust valve pipe 11 to discharge the unqualified steam. Meanwhile, the first pressure signal detector 5 detects the hot steam discharged from the superheater assembly 3. When the steam pressure is lower than the standard pressure, also open the first direct exhaust valve pipe 11 to discharge the unqualified steam. When the hot steam discharged from the superheater assembly 3 meets the usage standard, open the outlet valve 6 so that the hot steam is discharged along the outlet valve 6 into the steam recovery assembly 7. The hot steam in the steam recovery assembly 7 is detected by the flow detection assembly 16 and then discharged into the cut tobacco feeder to heat it. The steam with a lower temperature at the lower part of the steam recovery assembly 7 is discharged to other positions. When the second pressure signal detector 8 detects that the steam flow pressure in the superheater assembly 3 is relatively low, the transmitter 81 controls the second inlet valve 9 to input steam into the superheater assembly 3 to maintain the flow stability in the superheater. When the first pressure signal detector 5 detects that the pressure is lower than the standard temperature during the heating of the steam by the superheater assembly 3, open the pressure relief valve pipe 12 to discharge the steam, and recover it through the external pipeline transmission. To sum up, the superheater assembly 3 heats the steam to dry and dehumidify the input steam, thereby reducing the occurrence of water-carrying steam in the cut tobacco feeder. And through the cooperation between the second pressure signal detector 8 and the transmitter 81, the steam pressure in the superheater assembly 3 is kept stable, thus maintaining the steam pressure stability and avoiding the occurrence of wet cut tobacco lumps.

[0023] As Figure 1 and Figure 2 shown, it also includes an auxiliary drainage mechanism. The auxiliary drainage mechanism includes a second direct exhaust valve pipe 13, a Z-shaped pipe 14, and a third direct exhaust valve pipe 15. The lower left side of the first inlet valve 2 is connected to the second direct exhaust valve pipe 13. The middle right side of the second direct exhaust valve pipe 13 is connected to the Z-shaped pipe 14. The right part of the Z-shaped pipe 14 is connected to the third direct exhaust valve pipe 15 with a heat preservation function.

[0024] It should be noted that before starting up, the second direct drain valve pipe 13 is opened to drain the condensate in the pipeline before starting up. Then, the second direct drain valve pipe 13 is closed, and then the third direct drain valve pipe 15 is opened. During the process of superheating steam by the superheater assembly 3, the Z-shaped pipe 14 drains the condensate in the pipeline. In summary, the second direct drain valve pipe 13 and the third direct drain valve pipe 15 assist in draining the first direct drain valve pipe 11, making up for the shortcoming that the condensate cannot be drained in time and improving the steam dryness.
