(6) Meanwhile, high-temperature and high-humidity waste gas generated in the medicine preparation process of the medicine steaming machine passes through the medicine steaming exhaust pipeline and is cooled and liquefied by the waste gas recovery water tank and then is discharged to the outside;
(7) When the second temperature sensor senses that the temperature of the exhaust pipe of the condensate water recoverer is too high, the system controls the cooling cylinder to be communicated with the soft water tank, soft water in the soft water tank flows through the cooling inlet and the cooling outlet and then reenters the soft water tank, and the exhaust pipe of the condensate water recoverer is cooled;
(8) When the first temperature sensor senses that the water temperature in the waste gas recovery water tank is too high, the system conducts a pipeline between the waste gas recovery water tank and the hot water tank, hot water in the waste gas recovery water tank is discharged into the hot water tank for cooling, and the hot water tank discharges water into the condensate water recoverer and then into the water supplementing tank for continuous use;
(9) And opening a pipeline between the soft water tank and the waste gas recovery water tank, re-injecting soft water into the waste gas recovery water tank, and cooling and liquefying high-temperature high-humidity waste gas generated by the medicine steaming machine.
5. The method for using the pharmaceutical factory water circulation system according to claim 4, wherein: the water replenishing tank, the waste gas recovery water tank, the soft water tank and the hot water tank are internally provided with water level detection devices for monitoring the internal water level.
6. The method for using the pharmaceutical factory water circulation system according to claim 4, wherein: the boiler comprises a first boiler and a second boiler, the first boiler and the second boiler are connected in series through a pipeline, and the first boiler and the second boiler are communicated with the second water supplementing tank through a pipeline; the waste gas recovery pond includes first recovery pond and second recovery pond, first recovery pond with the second recovery pond sets up side by side, evaporate medicine exhaust duct in proper order cross-under in first recovery pond with the second recovery pond, and in the lateral wall in second recovery pond wears out and communicates with external environment.
