Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] The present invention is a new type of energy recovery and utilization device for pressure water pipelines, such as figure 1 shown. The device mainly includes a main production pipeline 6 and a bypass production pipeline 5 arranged in parallel with the main production pipeline 6. The main production pipeline is provided with a flow regulating valve 1, and both sides of the flow regulating valve 1 are provided with main pipeline valves. 4. The bypass production pipeline 5 is equipped with a hydraulic synchronous generator 2, and both sides of the hydraulic synchronous generator 2 are equipped with a bypass valve 3, and the flow regulating valve 1 is equipped with pressure gauges, flow meters and corresponding PLCs before and after the valve. Control System. Pressurized water enters the production process through the main production pipeline 6 th...

Abstract

The invention discloses an energy recycling device of a pressure water supply pipeline. The energy recycling device of the pressure water supply pipeline mainly comprises a flow regulating valve arranged on a main production pipeline, and is characterized in that a bypass pipeline is connected in parallel beside the main production pipeline and the bypass pipeline is provided with a hydraulic synchronous generator. The invention has the advantages that the rest energy of the produced excess water pressure can be recycled for assisting low power or illuminating systems in production facilities through simple and compact equipment installation, thereby being favor of saving the production cost and improving the energy-saving efficiency.

Description

technical field [0001] The invention relates to energy utilization and recovery design in municipal and water conservancy and hydropower pressure pipeline systems, and can be used in other related projects, in particular to an energy recovery and utilization device for pressure water transmission pipelines and a recovery and utilization method thereof. Background technique [0002] In my country's current municipal and water conservancy and hydropower pressure pipe systems, in order to meet the pressure requirements of the most unfavorable point, there is often a part of residual pressure (beyond the design required water pressure) before the pressure water system is used. Because this part of energy is often ignored or the stability of water supply flow is ensured through energy dissipation measures, on the one hand, it is necessary to increase energy dissipation equipment, and on the other hand, it causes a lot of energy waste. [0003] In many municipal and water conserva...
