Efficient and energy-saving negative pressure drainage collecting system

Abstract

The invention relates to the technical field of drainage systems, in particular to an efficient and energy-saving negative pressure drainage collection system which comprises a water diversion part, a drainage pipeline connected with the water delivery end of the water diversion part and an air suction pipeline connected with the air suction end of the water diversion part. The air suction pipeline is externally connected with an air suction pump, and the horizontal position of the air suction pump is higher than the water inlet position of the drainage pipeline. The drainage pipeline is externally connected with a spiral shunting pipeline, and the spiral shunting pipeline is of a spiral structure and is divided into a plurality of branch pipes; the output end of the spiral flow dividing pipeline is connected with a discharge branch pipe, the spiral flow dividing pipeline is vertically connected with the discharge branch pipe, an anti-reverse turnover piece is arranged at the joint of the spiral flow dividing pipeline and the discharge branch pipe, and the discharge branch pipe is externally connected into the confluence cavity; a spiral flow gathering assembly is arranged in the flow gathering cavity, the output end of the flow gathering cavity is externally connected with a discharging main pipe, and the spiral flow gathering assembly is used for guiding water flow into the discharging main pipe. The operation burden of the drainage collection system can be effectively reduced, the risk of damage to operation equipment is reduced, and the energy-saving and efficient drainage effect is achieved.

Description

technical field [0001] The invention relates to the technical field of drainage systems, in particular to an efficient and energy-saving negative pressure drainage collection system. Background technique [0002] The negative pressure drainage system is a system that uniformly collects the sewage distributed in the negative pressure intelligent collector at the end of the tree-shaped negative pressure collection pipe network into the negative pressure power center at the end of the system through negative pressure. The negative pressure intelligent collector in the prior art includes a water collection terminal, a sewage suction pipe, an interface valve, a pilot valve and a liquid level switch. During operation, the interface valve is opened to drain water for suction. [0003] However, there are certain defects in the existing technology. With the increase of the number of negative pressure collectors, the number of failures also increases significantly. Therefore, the fail...

Problems solved by technology

[0003] However, there are certain defects in the existing technology. With the increase of the number of negative pressure collectors, the number of failures also increases significantly. Therefore, the failure of negative pressure collectors greatly affects the stability of the entire negative pressure drainage system. The work performance is continuous pressure relief of the system, pressure relief of the pump station, continuous alarm, and a decrease in overall efficiency
