Embodiment Construction

[0069] Below in conjunction with embodiment the present invention is described in further detail:

[0070] Such as figure 1 as shown,

[0071] Step S101: Collect information such as the structural size of the pipe network, such as pipe length, pipe diameter, pipe material; , valve and other detailed information; etc.

[0072] All kinds of information collected should be comprehensive. Structural parameters are fixed data, generally provided by the design unit. After receiving the data, the data needs to be verified. In particular, the elevation difference of the pipe network is the altitude of each point of the pipe network. This has a great impact on the safe operation of the pipeline network.

[0073] Step S102: Collect operational data of the pipe network, such as ambient temperature; inlet and outlet temperatures of important nodes; pressure of important parts; current, voltage and frequency; etc.;

[0074] All collected data should have a time tag. The collected d...

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...
