Problems solved by technology

[0002] In the central heating system, most of them adopt the branch heating pipe network system, and centrally set the circulation pump to overcome the resistance of the pipeline and make the heat medium circulate. The use of this mode will inevitably cause the near-end user to use too much pressure head. To solve the excessive pressure head of the system, most of them eliminate the excess pressure head by throttling. Some manufacturers also adopt distributed frequency conversion technology to achieve the purpose of energy saving. However, the design of distributed frequency conversion technology is too complicated, and the adaptability to load changes is relatively small. Poor, and in the existing heating system, due to the complex structure, the transmission and distribution balance of the entire system cannot be guaranteed, resulting in energy waste and failing to achieve a good heating effect

Abstract

The invention provides a novel heat supply system. The novel heat supply system comprises a heat supply pipe network composed of a heat supply primary pipe network and a heat supply secondary pipe network. A water turbine is arranged on a water supply pipeline of the heat supply primary pipe network and is connected with the a supplement circulating water pump on a water supply pipeline of the heat supply secondary pipe network through a coupler transmission device. A main circulating water pump is further arranged on the water supply pipeline of the heat supply secondary pipe network. An electric adjusting valve is arranged between the main circulating water pump and the supplement circulating water pump. The coupler transmission device, the supplement circulating water pump, the electricadjusting valve and the main circulating water pump are electrically connected with a speed adjusting controller. A user heat exchange station is arranged among the water supply pipelines and water return pipelines of the heat supply primary pipe network and the heat supply secondary pipe network. According to the novel heat supply system, an available pressure head of the primary pipe network inthe heat supply pipe network system is effectively eliminated, an effective coupling system is formed by the primary pipe network and the secondary pipe network of the heat supply pipe network, a control center is additionally mounted, and therefore heat is distributed according to needs, and electric consumption of the circulating pump of the secondary pipe network is reduced.

Description

technical field [0001] The invention belongs to the technical field of thermal energy and power, and in particular relates to a new type of heating system capable of eliminating redundant pipe network pressure heads and regulating the heating network. Background technique [0002] In the central heating system, most of them adopt the branch heating pipe network system, and centrally set the circulation pump to overcome the resistance of the pipeline and make the heat medium circulate. Using this mode will inevitably cause the near-end user to use too much pressure head.

Some manufacturers also adopt distributed frequency conversion technology to achieve the purpose of energy saving. However, the design of distributed frequency conversion technology is too complicated, and the adaptability to load changes is relatively small. Poor, and in the existing heating sys...
