Abstract

The invention discloses a heating station system utilizing a residual pressure head of a primary side water supply system and a regulation and control method. The heating station system comprises a heat exchanger, a primary water supply system, a secondary water supply system, an analysis decision module and a control module, the primary water supply system comprises a primary water supply pipe, a turbine and an electric regulating valve, and the turbine and the electric regulating valve are arranged on the primary water supply pipe; and an outlet of the turbine is connected with an inlet of the electric control valve through the primary water supply pipe, an outlet of the electric control valve is connected with a primary water supply connector of the heat exchanger through the primary water supply pipe, and a first pressure signal collecting terminal is arranged at the inlet of the electric control valve. According to the heating station system utilizing the residual pressure head of the primary side water supply system and the regulation and control method, circulating power is provided for the secondary side water supply system by utilizing the residual pressure head of the primary side water supply system, throttling loss energy of a primary pipe network is recycled, and power consumption of a circulating power device of a secondary pipe network is reduced, so that good economic benefits and social benefits can be realized.

Description

technical field [0001] The invention relates to a thermal station system and a control method utilizing the residual pressure head of a primary side water supply system, and belongs to the technical field of energy saving of central heating systems. Background technique [0002] Central heating systems are generally used in cities and towns in northern my country to provide heating for residents in winter. At present, in the typical design mode, the selection of the circulating water pump at the heat source end (that is, the circulating water pump of the primary network) depends on the resistance requirements and heat demand of the most unfavorable loop at the farthest end. As a result, the heat station close to the heat source often has an excessively high resource pressure head. The current system solution is usually to install a regulating valve or throttle valve in the primary water supply pipeline of the thermal station to control the pipeline resistance and water flow...
