Energy-saving method and automatic energy-saving system for heat transfer pipe network optimization

Abstract

The invention discloses an energy-saving method and system for heat transfer pipe network optimization. The method comprises the following steps that (1), heat supply demands GJ1, GJ2...GJt of all heat supply demand points are acquired; (2), flow original values qa1, qb1...qt1 of all heat transfer pipes are acquired; (3), flow target values qa0, qb0...qt0 of all the heat transfer pipes are calculated; (4), a following data comparison table is formed through calculation, the adjusting number is 1 or m, and m is an integer and is larger than or equal to 2; and (5), the opening quantities of adjusting valves on the corresponding heat transfer pipes are adjusted, and then the heat supply demand of each heat transfer pipe is consistent with the heat supply amount of the heat transfer pipe. According to the method and system, accurate control over the adjusting valves can be achieved, therefore, supply and demand balancing of each heat transfer pipe is achieved, energy sources are saved, andthe cost is reduced.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to a method and an automatic energy saving system for optimizing energy saving of a heat transmission pipe network. Background technique [0002] The current energy station heating system usually supplies heat to multiple demand points through multiple heat transmission pipelines for one energy station. When heating is currently performed, the energy station only needs to supply heat ∑ according to the total thermal demand ∑ of multiple heat transmission pipelines, so that ∑ supply = ∑ demand, the heat supply for different heat transmission pipelines is not effective. Regulation, however, since the heat demand on each heat transfer line is not the same, therefore, if the heat supply on each heat transfer line is not effectively regulated, the heat supplied by each heat transfer line It is not equal to the heat required by the heat transfer pipeline, so it will cause a waste o...

Problems solved by technology

When currently supplying heat, the energy station only performs heat supply and Σ supply according to the total heat demand ∑ demand of multiple heat transmission pipelines, so that Σ supply = Σ demand, and the heat supply of different heat transmission pipelines is not effectively implemented. However, since the heat demand on each heat transmission pipeline is not the same, if the heat supply on each heat transmission pipeline is not effectively adjusted, for each heat transmission pipeline, the heat supplied by it It is not equal to the heat required by the heat transfer pipeline, therefore, it will cause waste of energy
