Regional heat supply system integrating pipe network grading and intelligent control, and transformation method

Abstract

The invention discloses a regional heat supply system integrating pipe network grading and intelligent control, and a transformation method. An energy station is used as a quasi-primary network, transformation is carried out based on a heat inlet, and the heat inlet originally used as a primary network is transformed into a quasi-secondary network; a heat branch and a heat tail end are transformedinto a quasi-tertiary network and a quasi-quaternary network correspondingly so as to realize flow control and load regulation irrelevant to the pressure in a control unit ring; a water pump and a pressure gauge are mounted on a water return pipeline of the quasi-primary network; and dynamic differential pressure balance valves and pressure gauges are mounted on water return pipelines of the quasi-secondary network and the quasi-tertiary network, a dynamic differential pressure balance valve and a water distributing and collecting device are mounted on a water return pipeline of the quasi-quaternary network, and communication modules connected with a monitoring platform are mounted in the quasi-primary network, the quasi-secondary network, the quasi-tertiary network and the quasi-quaternary network correspondingly.

Description

technical field [0001] The invention relates to the technical field of central heating, in particular to an energy-saving method for thermal system transformation of the existing district heating system "source network end" integrated management and control, specifically to the dynamic hydraulic balance of the district heating system, the hierarchical transformation of the pipe network and the intelligent The coupling of control technology provides a hardware foundation for realizing the time-division, division and temperature-division fine control of the heating system, maximizing energy saving and meeting the various heat demands of users. Background technique [0002] Centralized heating is a common form of heating in northern my country. Because the actual operating conditions of the heating pipe network are affected by many aspects such as manufacturing and construction, working conditions, and the environment, it is difficult for the traditional pipe network to eliminat...
