According to the requirement of the whole energy system on the temperature of the condensed water, the upper limit of the temperature of the condensed water in the recovery tank 1 is controlled to be 100 degrees, and as the high-temperature condensed water discharged by the steam trap 15 is mixed with the water stored in the recovery tank 1, when the temperature reaches 80 degrees, the pneumatic film valve 10 of the water inlet pipe 7 is opened, the low-temperature soft water enters the soft water coil pipe 3 after passing through the adjustable pneumatic film valve 10 and the first flowmeter 11, and the soft water is mixed with the condensed water in the recovery tank 1 through the drain hole 4 on the soft water coil pipe 3, so that the aim of reducing the temperature is achieved.

The smaller the difference between the actual temperature measured by the temperature sensor 5 and the set temperature 100 degrees, the larger the opening of the valve positioner 12, which proves that the water temperature is higher. If the water temperature exceeds 100 DEG, the opening of the valve positioner 12 is 100%, and simultaneously the electromagnetic valve 9 of the sewage pipeline 8 at the bottom of the recovery tank 1 is opened to drain condensed water into the sewage pipeline 8; when the water temperature is lower than 100 ℃, the electromagnetic valve 9 is closed, the valve positioner 12 of the pneumatic film valve 10 is in an open state and still carries out temperature adjustment until the water temperature in the recovery tank 1 reaches the set temperature, so that the overhigh temperature of condensed water in the recovery tank 1 is effectively prevented, and the problems of fermentation, mildew and peculiar smell generation in the recovery tank 1 caused by long-time retention of high-temperature condensed water are effectively solved.

This part of the condensed water is stored in the recovery tank 1 after natural cooling for the next day of use in reducing the temperature of the high-temperature condensed water.
(2) In the production process, the water level sensor 6 and the temperature sensor 5 participate in control, firstly, the condensed water is reduced to be below 100 degrees, and secondly, the condensed water is intermittently discharged into a closed recovery system from the discharge pipeline 22.
If the temperature sensor 5 monitors that the water temperature in the recovery tank 1 exceeds 80 degrees, the high-temperature water pump 17 accelerates the water drainage under the control of the frequency converter 20; under the control of the valve positioner 12, the pneumatic film valve 10 increases the valve opening, the soft water is injected in an acceleration way, and the water temperature in the recovery tank 1 is reduced rapidly until the water temperature is below 80 degrees.
Meanwhile, the condensate water discharge amount can be monitored through the first flowmeter 11 and the second flowmeter 18, after the signals acquired by the first flowmeter 11 and the second flowmeter 18 are input into the PLC module 24, the control program performs subtraction on the flow signals of the first flowmeter 11 and the second flowmeter 18, and the difference value is converted into the condensate water discharge amount of the steam using equipment. By monitoring the discharge amount of the condensed water, whether the steam equipment works normally or not is judged, and when the fluctuation rate of the discharge amount of the condensed water exceeds 5%, the system gives a warning prompt.
The working procedure of this embodiment is: in the production process, condensed water enters the recovery tank 1 through the steam trap 15, is mixed with low-temperature water in the recovery tank 1, the mixed temperature is detected by the temperature sensor 5 and then is input into the PLC module 24, and a control program executes whether to open the pneumatic membrane valve 10 to supplement soft water according to a set program; meanwhile, the water level detected by the water level sensor 6 and the pressure signal detected by the inlet of the steam trap 15 are simultaneously transmitted into the PLC module 24, and after the control program operation, whether the high-temperature water pump 17 is started or not is executed, and the back pressure of each steam trap 15 is detected to meet the requirement.
Moisture generated in the condensed water discharging process is discharged into the atmosphere from the moisture discharging pipeline 2 after being dedusted by peculiar smell.
After the production is finished, the steam in the pipeline and the steam using equipment is changed into condensed water, and then enters the recovery tank 1 through the steam trap 15, and whether the recovery tank 1 is allowed to store more condensed water at the moment is judged according to the water level of the recovery tank 1, and the condensed water is used as low-temperature soft water for cooling the next day.
