Application Publication Number: CN107151936 A Inventor: Zhang Zhen Zhen Tian Wei Tian Jin Tang Yuanyu Li Yi Applicant: Zhong Lian Northwest Engineering Design and Research Institute Co., Ltd. paper mill suction tank vacuum device, the traditional design is “open water ring vacuum pump ”Or “ filter + open water ring vacuum pump ”non-condensable gas and water extraction to ensure the degree of vacuum to ensure product quality. Water ring vacuum pump working fluid is water, the design temperature is 15 ℃, if the working fluid temperature is higher than the design value, the vacuum pump will change the nature of work. In use, the device has low efficiency and high energy consumption (speed of 1150 m / min, equipped with a 185 kW water ring vacuum pump); water ring really
