Abstract

The invention discloses a vacuum drainage system capable with quick-opening passive vacuum sewage discharge valves and a drainage method. The vacuum drainage system comprises a plurality of sewage collection tanks, a vacuum smashing tank and a vacuum pump; the sewage collection tanks are parallelly connected to one end of a first vacuum pipe through connection pipes, the vacuum smashing tank is connected to the other end of the first vacuum pipe, and the vacuum smashing tank is connected with the vacuum pump through a second vacuum pipe; the vacuum pump is connected with a sewage discharge pipe, the quick-opening passive vacuum sewage discharge valves are arranged in all the sewage collection tanks, and the vacuum sewage discharge valves comprise control tanks, floating tanks and ball conveying tanks which are arranged in the sewage collection tanks; balls are arranged in the ball conveying tanks, the ball conveying tanks can move up and down with the floating tanks along the control tanks, and ball inlets and ball outlets are formed in the control tanks respectively; open-close reset mechanisms with pull rods and driving rods are further arranged in the sewage collection tanks, the pull rods are connected with the constant-closed vacuum sewage discharge valves, and one end of each driving rod extends into the corresponding control tank and is located between the corresponding ball inlet and the corresponding ball outlet.

Description

technical field [0001] The invention relates to a vacuum drainage system and a drainage method, in particular to a vacuum drainage system and a drainage method with a fast opening passive vacuum sewage valve. Background technique [0002] The problem of waterlogging after heavy rains in cities is still criticized by people because there is no proper solution. An important cause of urban waterlogging is the slow speed of traditional gravity drainage. The drainage system commonly used in China at present is the centrifugal pump type drainage system. In the case of drainage mainly relying on gravity, the drainage speed is unsatisfactory. If the area of ​​accumulated water under an urban overpass reaches 500 square meters and the depth of accumulated water reaches 8 meters, it will take at least 85 minutes to drain the water with the current commonly used drainage system, which is 50 minutes different from foreign advanced equipment. Those 50 minutes can be precious if drainag...
