Pipe network heat storage system based on series connection of heat supply network supply and return mother pipes and regulation and control method of pipe network heat storage system

Abstract

The pipe network heat storage system comprises a heat supply pipe network, the heat supply pipe network comprises a heat supply network initial station, a heating station, a circulating water pump, a primary network water return pipe and a primary network water supply pipe, and a heat supply network water bypass is installed between the primary network water supply pipe and the primary network water return pipe; an adjusting assembly is arranged on the heat supply network water bypass and used for adjusting the flow and pressure of heat supply network water flowing through the heat supply network water bypass, and the heat storage and heat release functions are achieved through an existing heat supply network. For a cogeneration heat supply system, the heat storage capacity of an existing huge heat supply pipe network is fully utilized to increase the peak regulation capacity of a cogeneration unit, and the huge investment cost of a newly-built energy storage device is saved.

Description

technical field [0001] The invention relates to the technical field of central heating, in particular to a pipe network heat storage system based on a heat network supply and return to the main pipe in series and a control method thereof. Background technique [0002] As an important way of efficient and clean utilization of energy in the power and heat industries, cogeneration has become an important way for the development of thermal power generation in countries around the world, and has been included in my country's key energy-saving projects and the main way of clean heating. In recent years, the rapid development of new energy power generation has brought severe power peak regulation requirements to thermal power generation. However, the operation mode of conventional cogeneration units based on heat and electricity has severely restricted the flexible adjustment of thermal power, resulting in heat supply and electricity. There is a serious conflict in power peaking. ...

AI Technical Summary

Problems solved by technology

However, when there are too many thermal stations in the heating system, this patented technology needs to add a large number of heat network water bypasses and valves and other related facilities, which also increases the construction investment cost to a certain extent. At the same time, the adjustment is complicated and difficult to achieve. Precision heating
