The following example is to reduce the temperature and pressure of high-temperature high-pressure steam with pressure of 1.5MPa and temperature of 220 ℃ from municipal steam pipe network to steam with pressure of 0.5MPa and temperature of 152 ℃ (which can be set according to the requirements of end users and equipment in summer and winter), and the pressure and temperature regulation process of the present invention is adopted:
pressure regulation:
the preset expected pressure in the control device 8 is 0.5MPa, when high-temperature high-pressure steam passes through the second pressure sensor 9, the second pressure sensor 9 detects that the pressure of the high-temperature high-pressure steam is 1.5MPa, the second pressure sensor 9 sends the pressure of the high-temperature high-pressure steam to the control device 8, the control device 8 compares the pressure of the high-temperature high-pressure steam with the preset expected pressure to control the first electric pressure reducing valve 2 to reduce the pressure, the pressure reduction amplitude is realized by controlling the first electric gate valve 11 through the control device 8, the control device 8 controls the second electric gate valve 12 to be normally open and not to act in a normal operation state, the first pressure sensor 5 detects the actual pressure of the temperature and pressure reducing steam and sends the actual pressure of the temperature and pressure reducing steam to the control device 8, if the actual pressure of the temperature and pressure reducing steam is higher than the preset expected pressure, the control device 8 controls the first electric pressure reducing valve 2 and the first electric gate valve 11 to further reduce the pressure, and if the actual pressure of the temperature and pressure reducing steam is lower than the preset expected pressure, and the pressure reducing degree of the first electric gate valve 2 and the first electric gate valve 11. When the first electric pressure reducing valve 2 is in fault and needs to be overhauled, the control device 8 controls the first electric gate valve 11 and the second electric gate valve 12 to be closed to cut off steam, and therefore overhauling safety is guaranteed.
Temperature regulation:
the preset expected temperature in the control device 8 is 152 ℃, when high-temperature high-pressure steam passes through the second temperature sensor 10, the second temperature sensor 10 detects that the temperature of the high-temperature high-pressure steam is 220 ℃, the second temperature sensor 10 sends the temperature of the high-temperature high-pressure steam to the control device 8, the control device 8 compares the temperature of the high-temperature high-pressure steam with the preset expected temperature to control the first desuperheating water conveying device 13 and the second desuperheating water conveying device 14 to start, controls the first electric water feeding valve 7 to open, sprays desuperheating water through the first atomizing nozzle 16 to cool, detects the actual temperature of the desuperheating and depressurizing steam through the first temperature sensor 6 and sends the actual temperature of the desuperheating and depressurizing steam to the control device 8, and if the actual temperature of the desuperheating and depressurizing steam is higher than the preset expected temperature, the control device 8 controls the first electric water feeding valve 7 to adjust the valve opening degree of the first electric water feeding valve 7 to be larger, so that the desuperheating amplitude is controlled. The second electronic feed valve 15 normal close of connecting second atomizing nozzle 17 under the normal operating condition does not move, and it is lower to require when the terminal service temperature in summer, and preset expectation temperature is lower promptly, and when first electronic feed valve 7 desuperheating can't satisfy the requirement, control second electronic feed valve 15 by controlling means 8 and open, spray the cooling water cooling through second atomizing nozzle 17, spray the cooling water together through second atomizing nozzle 17 promptly and second atomizing nozzle 16 and 17 and reduce steam temperature and satisfy end user's practical demand.
