Method and device for improving suction lift of vacuum drainage system
The invention discloses a method and device for improving the suction lift of a vacuum drainage system. A sewage pump (2) is used for controlling the amount of sewage in a sewage tank (1); a vacuum pump (3) is used for controlling the air pressure in the sewage tank (1); the sewage tank (1) is connected with a lifter (7) through a vacuum sewage pipe (6), a vacuum sewage suction pipe (73) and an interface valve (71), and a sewage suction port of the vacuum sewage suction pipe (73) enters the lifter (7); sewage is discharged into the lifter (7) through a sanitary ware (8), then the interface valve (71) is opened, the sewage tank (1) communicates with the lifter (7), air is sucked into the vacuum sewage suction pipe (73) below the interface valve (71) and above a sewage suction port of the vacuum sewage suction pipe (73), and the sewage in the lifter (7) is discharged into the sewage tank (1). According to the technical scheme, the suction lift of the vacuum drainage system can be improved, so that the application scene of the vacuum drainage system is wider.
本发明公开了一种提高真空排水系统吸程的方法及装置，使用排污泵(2)控制污水罐(1)内的污水量；使用真空泵(3)控制污水罐(1)内的气压；使用真空污水管(6)、真空污水吸入管(73)和界面阀(71)将污水罐(1)和提升器(7)连接，真空污水吸入管(73)的吸污口进入提升器(7)内；将卫生器具(8)将污水排入提升器(7)内，然后打开界面阀(71)，使污水罐(1)和提升器(7)连通，界面阀(71)下方与真空污水吸入管(73)的吸污口上方的真空污水吸入管(73)内吸入空气，将提升器(7)内的污水排入污水罐(1)，本技术方案可以提高真空排水系统的吸程，使真空排水系统的运用场景更广。
