Long-distance heat supply pipe network operation heat storage adjusting method

Abstract

The invention discloses a long-distance heat supply pipe network operation heat storage adjusting method, which relates to the technical field of urban long-distance heat supply, and comprises the following steps: collecting structure size information and operation data of a pipe network, and cleaning the data; establishing a theoretical model of energy conservation, establishing a heat storage model, establishing an artificial intelligence model of energy conservation, verifying the obtained water supply temperature of the first station, establishing a resistance characteristic model, judging whether the current total resistance of the pipeline meets the requirement or not, establishing a numerical model of pressure characteristics, and judging whether the numerical model of the current pressure characteristics meets the requirement or not. And the water supply temperature for heat storage is output. The operation method is simple, the workload of operators is relieved, the heat transfer efficiency is high, the heat supply comfort of users is guaranteed, it is guaranteed that the long-distance heat supply pipe network prevents water hammers, and conveying energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of urban long-distance heat supply, in particular to a heat storage adjustment method for long-distance heat supply pipe network operation. Background technique [0002] The so-called long-distance heating pipeline refers to the hot water pipeline network with a length of more than 20km from the heat source to the main heating load area. The heating system usually includes a relay pump station, a relay energy station or a pressure isolation heat exchange station, long-distance heat supply pipelines and accessories, etc. According to Article 4.2.2 of the industry standard of the People's Republic of China "Code for Design of Urban Heating System" (CJJ34-2010): When the technical and economic comparison of the optimal supply and return water temperature is not available, the hot water pipe network supply, The return water temperature can be determined according to the following principles: 1) When thermal pow...

Problems solved by technology

[0017]At present, for the long-distance heating pipeline network, due to the relatively short time of appearance, rich operation experience has not yet been accumulated, and a new operation adjustment method needs to be proposed
